Trimming, flanging and side punching compound die

Abstract

The invention discloses a trimming, flanging and side punching compound die which comprises an upper die and a lower die, wherein the upper die is provided with a trimming upper die, a flanging upper die and a side punching upper die; the lower die is provided with a nitrogen spring, a trimming lower die, a flanging lower die and a side punching lower die; the trimming upper die is provided with casting polyurethane, a pressing plate and an upper die trimming block; the trimming lower die is provided with a lower die trimming block and a cylinder ejection mechanism; the flanging upper die is provided with a concave die, a flanging block, a stripping mechanism, a stripping nitrogen cylinder, a pressing plate nitrogen cylinder, an upper die pressing plate and a hole flanging punch; the flanging lower die is provided with a convex die, a setting gage and a lower die pressing plate; and the side punching upper die is provided with a side punching punch, a polyester cyanamide pressing mechanism, a slide wedge and a roller wheel. By using the mode of the compound die, several processing procedures of trimming, flanging and side punching of workpieces made of metal plates can be completed through one set of die, once feeding is performed, the processing accuracy of the workpieces is high, the production efficiency is high, and the die cost is saved.

Description

technical field [0001] The invention relates to a metal plate part processing die, in particular to a composite die for trimming, flanging and side punching. Background technique [0002] Trimming, flanging, and punching processes are widely used in the processing and production of automobile sheet metal parts. The traditional processing method is to use trimming, flanging, and punching molds respectively. The number of molds required is large, and the cost of molds is high. Production The efficiency is low, and the use of several sets of molds for multiple clamping of materials and multiple positioning results in product positioning deviations between different processes, resulting in product processing errors and affecting product quality. Moreover, these traditional trimming, flanging, and punching dies have a large vibration and impact during work, which generates noise and vibration, which has a great impact on the working life of the die, and it is inconvenient to chec...

The traditional processing method is to use trimming, flanging, and punching molds respectively. The number of molds required is large, and the cost of molds is high. Production Low efficiency, and the use of several sets of molds for multiple clamping of materials and multiple positioning results in product positioning deviations between different processes, resulting in product processing errors and affecting product quality

Moreover, these traditional trimming, flanging, and punching dies have a large vibration and impact during work, which generates noise and vibration, which has a great impact on the working life of the die, and it is inconvenient to check the die test, and it is not easy to judge the die processing Effect
