What are the functions of precision steel frame punch?
What are the specific functions of precision steel frame punch? Let's take a look together next.
1. Before processing and assembling the precision steel frame punch, we must first have a clear understanding of the mold structure, working principle, product shape, vehicle matching relationship and related process modeling, so as to understand the fillet, ridge, and impact marks in the assembly process. There is a clear understanding of factors such as the angle of the draft surface, so that the thinking and order are clear in the assembly and debugging process, which not only improves the work efficiency, but also ensures the quality.
2. The feed resistance of each part of the pressing surface is different. The precision steel frame punch is easily affected by the movement of the top of the punch and affects the surface quality, and may even cause serious cracks and wrinkles. Make the transition of the pressing surface smooth, the feed resistance is uniform, the contact part of the punch and the stretched blank is close to the center when the punch starts to stretch, and the stretch forming is good. In order to uniformly feed each part of the surface of the nip resistance, in addition to the shape design of the passing nip surface and reasonable measures to draw the bead, the gap diagram design should also be closely combined during processing and assembly, and the drawing die presses the material. Place 50 outside the drawbead on the surface, and the blanking surface will be reduced by 0.15; the height of the drawbead is digitally modeled, and the groove depth of the drawbead is increased by 1 mm.
3. Under the condition of ensuring the secondary processing in place, the drawing die should be repaired and polished during the assembly design process. Try to avoid the use of grinding wheels, electric grinder tools for the surface, ridge fillet, etc. Carry out research and polishing, so as not to affect the quality of product development and molding work. On the contrary, you should first use oilstone and then use sandpaper for polishing. Each type should be carried out in strict accordance with the requirements of the first coarse and then fine method. The polishing should not be carried out because of the sawing method, but should be gradually advanced in the same direction.
The above is the full content of what the functions of precision steel frame punch are reflected in. I hope it can be helpful to you.
