Car Ban gold use cold punch craft to make for the most part. In actual production, regular meeting of stamping workpiece of car Ban gold appears all sorts of blemish: Corrugate, fold makings, neck to shrink, spring back, cut a margin not neat, burr, press injury and skid wire to wait. The spare parts folds makings blemish to be able to cause a spare parts to discard as useless. Combine working experience now, the analysis solves stamping workpiece of car Ban gold to fold the solution of makings problem. Stamping workpiece of gold of some car Ban finishs the savagery after figuration working procedure, extent is shown in red circle, existence of this spare parts folds makings blemish. These two area are with other part match area, fold stuff is serious the dimension percent of pass that drops white automobile body. Case study is as follows. Feature of part of the part before improving designs an element. The material when existence folds the product feature design of makings area to cause punch gathers easily, once material flows not free, can appear fold makings problem. Analysis of cause of formation: Element of craft of spare parts punch. This spare parts uses figuration technology, on one hand, the effect that uses figuration craft to control material to flow relatively pull delay craft difference, go against restrain fold makings problem. But to automobile body inside board the part with spare parts and minor dimension, to raise overall material utilization factor, reduce truckload cost, when designing punch technology, do not use pull delay craft, and use figuration technology. On the other hand, punch direction also is gone against fold makings area to flow in the material in punch process. The condition of this spare parts that figuration process completes after improvement folds makings problem to be improved apparently. Direction of the punch after improving because took the step below,this is: Optimize design of spare parts feature. The digital-to-analogue after improvement was folding makings area to add a muscle each. Addition muscle can develop the data that collect, improve thereby fold makings problem. Add muscle need considers two respects factor: One party gluten cannot cause a spare parts to match interference; on the other hand muscle height cannot too tall, can cause punch intensity inadequacy otherwise. Increase so suck makings muscle measure is narrow, improve a spare parts to fold the effect of makings finite also. Optimize craft of spare parts punch. Because increase,suck makings muscle the effect that solves a spare parts to fold makings problem is finite, at the same time so the consideration optimizes the punch craft of the spare parts. When using figuration technology, can adopt the punch way with logical choice, optimize data flow, restrain fold makings blemish. Adopt the punch way after improving, benefit flows in the material when punch at folding makings area, improve thereby fold makings phenomenon. CNC Milling CNC Machining
