Right electro-hydraulic hammer undertook multinomial innovation is designed, innovation goes have " the characteristic that install forge " electro-hydraulic hammer product, the introduction is as follows: ⑴ .

Designed " X " form slideway structure: Domestic evaporate, of empty forging hammer comb form slideway exists weak point of the arm of force, pass the fixed position, defect that compensates a function without temperature. Die to do not make peen expands to make slideway clearance is reduced and cause check because of warming up, be forced to increase the cold conditions space of slideway. Lever of the hammer when blow endures add turn moment, easy rupture, the slideway when be being used at much model antrum to forging wears away serious. To overcome this weakness, we are right electro-hydraulic hammer lead plane undertook innovating designing, use " X " form slideway structure. Because X slideway has longer the arm of force, the heat of peen expands direction and slideway extent direction agree basically, when heat expands, affect to slideway clearance not quite, slideway clearance can be moved very smally (0.

2mm controls) , make so forging the process slants mediumly knock power, be assumed entirely by peen slideway, make hammer lever life rises greatly. ⑵ .

Prolong sealed life, avoid change of oil gas each other: A.

The antrum on crock of job of fluid air hammer is high-pressured nitrogen, next antrum are high-pressured oil, because this is inchoate electro-hydraulic hammer is very incidental B.

Use wear-resisting, high temperature resistant oriented annulus and the Ky group that have stronger compensation capacity. C.

According to sealing oil is mixed those who seal gas medium is different, choose the Ky group with Shao different hardness. D.

Strengthen the fixed position of head. ⑶ .

Solve be not lever of normal life hammer to rupture problem: A.

Improve hammer lever and peen connection way, according to tribology principle, the design gave 3 (casting die, awl is covered, hammer lever) go up strict construction, make hammer lever by original " Shuang Zhui structure " instead " Chan Zhui structure " , avoided the generation that stress centers greatly, achieved thereby already connection disassembles again reliably convenient. Twice of hammer lever life rises. B.

Hammer lever surface undertook boiling pressing handling, raised case hardening layer, improve the service life of hammer lever thereby. ⑷ .

Solved the flexibility problem of a powerful person; Inchoate electro-hydraulic difference reachs hammer operation flexibility to fall slow the start is bad it is a problem that the user headaches all the time, once had circulated in the past " free forge is electro-hydraulic hammer is not free " , be aimed at this one problem, we take the following step: A.

Improve the design of 2 class a powerful person, increase the acreage of reduce expenditure aperture, rise to fall slow thereby the discharge in the process and velocity of flow. B.

Shorten advocate a powerful person and the distance of 2 class a powerful person, come true " 0 distances " join, shortened thereby the response rate of 2 class a powerful person, removed the effect of cubage effect. ⑸ .

Theory of thick hammer lever is used at head to transform; Electro-hydraulic hammer is flexible theory of fine hammer lever is very famous, it is creation of German Lasco company, electro-hydraulic hammer is flexible fine hammer lever is academic, changed former evaporate thoroughly, of empty forging hammer " slideway, peen, hammer lever " rigid condition of the system, make forging the process slants mediumly knock power, be assumed for the most part by peen slideway, this to free forging hammer, because its forging craft characteristic, slant knock power not quite, at this moment flexible just in time of fine hammer staff produces its distinct advantage. But the modular forging hammer that forgings to much model antrum is carried out " exchange a head " transform, "Flexible fine hammer lever is academic " it is inapplicable apparently. Slant as a result of what much model antrum forgings knock power very big, plus eventually when forge cold attack a phenomenon serious, so, bring about slideway inchoate damage is serious, appear even " card hammer " phenomenon. Accordingly, we are undertaking " exchange a head " when transforming, forging to much model antrum and slant the die forging weight that carries muscularity, still evaporate of continue to use, of empty forging hammer " lever of tigidity thick hammer is academic " , obtain satisfactory result. ⑹ .

Innovation designs structure of interior of the bridge that connect a crock; Inchoate electro-hydraulic hammer head from advocate operation a powerful person arrives valve base of 2 class a powerful person is do not have by seam a canal to be linked together, two end solder. This canal suffers in working process hand in change load, when peen returns, this canal zone carries, when peen is hit, this canal discharge carries on his shoulder or back, go round and round, so more abominable to operating mode hammer can appear the phenomenon of pipe rupture and welding line craze. Because this is in charge of the casing interior in the bridge that connect a crock, once invalidation, very difficult rehabilitate, although repair assures quality very hard also, so it makes a bigger hidden trouble, also be the main factor that affects head life. To solve this problem, we move valve base of 2 class a powerful person directly advocate below a powerful person, take out this solder take-overs, and cylinder body uses whole high grade cast steel, realize those who link crock bridge interior to turn connection without the canal thereby, rose electro-hydraulic the dependability of hammer key spare parts. ⑺ .

Development designed the big a powerful person or family that open way and 2 class a powerful person; As big tonnage electro-hydraulic hammer develops a design, advocate oil of the antrum below the crock is annular the area is larger and larger, the quick release valve that must form a complete set opens way and advocate a powerful person, ability assures the blow energy of big tonnage hammer and blow frequency. We are in original 50 model the development on the foundation of a powerful person designed form a complete set 70 model advocate a powerful person and 2 class a powerful person, develop again after 80 model advocate a powerful person and 2 class a powerful person. We are in 1 ton, 2 tons of free forge and die forging are electro-hydraulic hammer is used 50 model a powerful person, in 3 tons free forge mixes 3 tons, 5 tons of die forging are electro-hydraulic use on hammer 70 model a powerful person, in 5 tons free forge is electro-hydraulic use on hammer 80 model a powerful person. ⑻ .

Prevent device hitting a top new-styly to make protect more on the safe side; The peen motion characteristic of free forging hammer is to be hit quickly, carry quickly, peen hits a plane rate is high, characteristic to the amortize of amortize crock demand is high. Through be opposite inchoate electro-hydraulic analysis of defect of structure of hammer amortize crock, we improved a design, the gas antrum along with of amortize crock and accumulator, make its pressure matchs, rose to prevent the dependability that hits a top. ⑼ .

Solve a system calorific problem is electro-hydraulic hammer system is calorific problem, also be a very big technology difficult problem, it affects sealed function of the system and character of service badly, to this, we took the following step, controlled a system effectively calorific problem. It is utmost ground reduces systematic fluid block, logical choice vitta opens way, control velocity of flow inside reasonable range, 2 it is to rise advocate a powerful person and ability of caustic of wear-resisting of 2 class a powerful person, decrease inside discharge, 3 it is to use medicinal powder the cooling pump of the board type heat exchanger with hot taller coefficient and larger flow, increase cooling rate and oily circular number. ⑽ .

Solve problem of oil path vibration; Electro-hydraulic the problem of oil path vibration of hammer, to the system moving reliably also is one great harm. For this we use block to break the method that shakes source and amortize vibration wave, obtained very good result. It is every and conduit of lead plane connective and use stretch connection with conduit of high pressure of connective of hydraulic pressure station; 2 it is in high pressure the canal increases amortize accumulator on the road; 3 it is pressure watch is used entirely be able to bear or endure shake pressure watch, watch rise with suspension of 4 extension spring, join the canal uses miniature glue to provide link. 2, complete hydraulic pressure is electro-hydraulic hammer complete hydraulic pressure is electro-hydraulic hammer is working crock medium of fluctuation antrum job uses hydraulic pressure oil entirely, the antrum below working crock receives accumulator to be pressed normally from beginning to end, system of hydraulic pressure control is separate to going up antrum is controlled. When carrying weight, control blow a powerful person makes go up antrum puts through gasoline tank, can come true. When blow, control blow a powerful person makes go up antrum and UniCom finishing speech, fluctuation antrum oil pressure is right now equal but action area size is different, can realize differential blow consequently. Can see from the principle, in attacking a process fluctuation antrum wants pass in and out is oily at the same time, twin-circuit flows, because this is oily fast accept very big restriction, otherwise efficiency will be very low, best settlement means is to reduce velocity of flow. One but rate falls, should carry the condition with blow changeless energy (E=1/2mv2) , peen quality must be increased. And the blow frequency that should keep taller second if, must reduce the travel. Say simply even if " sledge head, short distance " , because hammer of this complete hydraulic pressure applies to modular forging hammer to go up only, on the modular forging hammer that suits programmed control especially, and do not suit adversary to move the free forge with operation very strong flexibility to go up. This kind is academic, we can develop a trend to get test and verify from the forging hammer on international. 3, hammer of die forging of programmed control complete hydraulic pressure 1, principle: The fundamental of hammer of die forging of programmed control complete hydraulic pressure is: Use oil pump - accumulator drive, the antrum below oil cylinder is pressed normally, hydraulic pressure system to going up antrum undertakes single accent is controlled. On antrum inlet valve (also say to strike a powerful person) open, come from oil pump, accumulator and antrum that draw through differential loop in all oil of 3 parts high pressure is entered on antrum, the acceleration that realizes peen is down and hit the journey, go up antrum once discharge pressing, peen returns quickly instantly, hit energy to close the accident of time will come true in order to dominate blow a powerful person or family. 2, basic structure ⑴ .

Airframe takes pillar and hammering block be an organic whole " U " form airframe. Although this kind of configuration gives cast, the difficulty with rise to be brought with machining again certain, but be like next advantages however: A.

Those who added pillar is fore-and-aft, transverse with capsize stiffness, ensured of peen direct accurately, be helpful for raising the utilization rate of raw material; B.

U form airframe makes 2 pillar also become hammering block the one part of weight, be helpful for overall of weight reduce and hit efficiency rise; C.

The blow noise that U form sincere casts airframe to arise is less than the airframe of pillar of form of box form He Gong apparently. ⑵ .

Slideway: Domestic evaporate, of empty forging hammer comb form slideway has weak point of the arm of force, without temperature compensatory defect. Die to do not make peen expands to make slideway clearance is reduced and cause check because of warming up, be forced to increase the cold conditions space of slideway, this is in namely evaporate, the reason that accurate die forging has hard on empty forging hammer. The hammer into shape of complete hydraulic pressure of 50KJ programmed control that my company develops is used " X " form slideway structure. Because radial radiate shape is shown to expand when peen be heated, spigot surface shows diagonal to decorate, won't expand because of peen be heated and reduce oriented gap. The programmed control hammer of my company increased the breadth of guide plate, x form slideway has longer the arm of force again, this is reduced with respect to can apparent ground slant the action when attacking on slideway face than pressing, be helpful for prolonging the service life of guide plate. ⑶ .

A of hydraulic pressure system.

Hydraulic pressure system uses oil pump, accumulator combines drive, advocate the antrum below oil cylinder is interlinked with accumulator from beginning to end, to often be pressed. Hydraulic pressure system is controlled only on antrum, it is the volume that hits energy through closing to striking a powerful person the control of time will come true, striking a powerful person is a powerful person of 3 class control, priority valve is 2 3 reversal valve, the system is very expensive to its quality requirement, should have high frequency rate already and repeat precision the demand is higher, accordingly we choose an entrance to be installed formerly; B.

Blow a powerful person uses structure of awl a powerful person, compare with traditional pilot valve photograph, have without tatty advantage, sealed dependability rises greatly; C.

Gasoline tank uses structure of type carrying buy on the head, in-house oil path closes in advocate on piece of a powerful person, such structure makes hydraulic pressure system came true compositive change, use with gasoline tank by photograph of buy type construction is compared, pipeline system length shortens greatly, energy loss reduces 1 times above, pass additionally compositive change, oil path join came true to turn connection without the canal, increased connective dependability; D.

Be in in hydraulic pressure system accumulator and relief valve was installed between next antrum, once hammer lever from which rupture, equestrian admiral issues antrum oil and accumulator to cut off, enhanced use security thereby. ⑷ .

Decrease brace up the system uses Germany (Qingdao) lie between and solid technology, kept apart the vibration that forging hammer produces in attacking a process thereby. ⑸ .

Programmed control system is a basis energy of blow of forging demand programme controll and blow frequency, the hammer of programmed control complete hydraulic pressure of my company uses OMRON medium-sized C200HS but program controller, deserve to input output module with the number, in order to hits energy in the set on Control Panel. 4 imitate are used to measure an input in protection system. Electromotor is used bury temperature sensor method beforehand, collect temperature data to be analysed in order to offer PLC, oil is lukewarm with insert type sensor to collect oily lukewarm change, PID(of whole process of in order to is controlled circularly) adjust. 3, function characteristic ⑴ .

Can realize the accurate control that hits energy. Hammer of this programmed control closes through controlling those who strike a powerful person accurately time, assured the energy that forging place requires already, do not produce additional concussion kinetic energy again, the life that because this a few crucial component are like hammer lever, peen,reachs fluctuation mould rises greatly. ⑵ .

Opening speed is very fast. As a result of advocate the antrum below oil cylinder connects accumulator from beginning to end, go up antrum once discharge pressing, can carry quickly hammer, because this mould contacts time weak point, this function and energy dominate photograph union accurately, can make forging die service life raises 1 times above. ⑶ .

Forging precision is tall: This product is used as a result of slideway " X " shape structure, because this slideway clearance can be moved very smally, the forging precision that makes is very tall. ⑷ .

Overall material utilization factor can be controlled very high as a result of energy, make base precision consequently very tall, the forging flash that hits is relatively even, because forging precision is tall, fluctuation model won't appear wrong standard phenomenon, overall material utilization factor is very accordingly high, laid a foundation to do not have cutting less. ⑸ .

Low noise belongs to blow energy as a result of this product but programmed control equipment, because of program of this work out, make forging is hit into, but do not give odd energy more, noise is very accordingly little. The handlers of traditional forging hammer is to rely on to listen to a mould to hit rely on sound to judge forging to whether be hit into, judge sometimes forbid, be used to many dozens a few times, actual it is redundant. ⑹ .

Adopt measure of aperture of reduce expenditure of mathematical calculation and Konghe of the damp in designing hydraulic pressure system without phenomenon hitting a top, make peen reachs the summit amortize comes down, very smooth, without the happening that bumped into a phenomenon. ⑺ .

Low vibration hits energy as a result of this product but programmed control, arise without redundant energy, add hammer body bottom to lie between and originally of what German technology produces brand vibration isolator, right all round machine tool, residential area does not have any influences. ⑻ .

Environmental protection: Because this product is in blow process, concussion noise is little, have vibrating absorber again, vibration is little, it is a kind of environmental protection product consequently. ⑼ .

Forging quality is relatively stable because connect the control of controller of process a type of local school in ancient times, of various forging forging working procedure can stock a program in, come out to use according to needing shift at any time, because this is same kind of blow energy that forging can get accord and blow frequency, avoided the diversity of artificial operation, because this forging quality compares stability. 4, the hand uses weight of die forging of complete hydraulic pressure 1, principle: The fundamental that the hand uses weight of die forging of complete hydraulic pressure is: Use oil pump- - accumulator drive, will control 4 to connect diameter to insert outfit a powerful person to come true greatly through action of the priority valve since pilot valve of a hand carry hammer, dangerous fall hammer, slow, the movement such as blow. 2, the actor defect that compares with photograph of programmed control hammer: Advantage: ⑴ .

Manipulator compose already but the hand moves an operation, also but the foot stamps an operation, the size of energy relies on handlers to control peen journey to come true, the operation is more agile. ⑵ .

The structure is simpler, maintenance is convenient. Defect: ⑴ .

Energy cannot be controlled accurately, realize nicety to forging hard; ⑵ .

Because weight of programmed control of oily pressure ratio is little, the journey is accordingly longer, blow frequency is lesser, produce efficiency on the low side. CNC Milling CNC Machining
