A semi-automatic stainless steel pull ring forming process and its forming die

Abstract

The invention discloses a semi-automatic stainless steel pull ring forming process and a forming mold thereof. A semi-automatic stainless steel pull ring forming mold includes an upper mold device and a lower mold device. There is a female die, and the pull ring is stamped and formed through the adaptation of the male die and the female die. The upper die device is also provided with a guide sleeve, and the lower die device is also provided with a guide post. The upper die device is adapted through the guide sleeve and the guide post. The mold clamping and mold splitting actions are performed relative to the lower mold device. Through punching, cutting, shaping, pressing, shaping, cutting and other processes, the finished product of the pull ring is finally formed, which has the characteristics of rapid prototyping, high production efficiency, consistency of front and rear products, and low defect rate.

Description

A kind of semi-automatic stainless steel pull ring forming process and forming die technical field [0001] The present invention relates to the field of stamping and forming, in particular to a semi-automatic stainless steel ring-pull forming die. Background technique The pull ring on the pot cover is a common pulling device, but the prior art is to use artificial Finished, first make size marks on the pull ring material, then punch holes according to the marks, cut them, and finally grind them with a grinding wheel. The artificial production and processing time is long, the efficiency is slow, and the precision is not high. When the surface is bolted to the lid, it cannot be matched with the bolts. If the hole is small, it can be reworked. When the hole is large, it cannot be used. This results in an increase in defective products and an increase in costs. At the same time, manual cutting is used, resulting in uneven surface of the pull ring, and it is easy to Dam...

AI Technical Summary

Problems solved by technology

[0002] The pull ring on the pot lid is a common lifting device, but in the prior art, when producing the pull ring of the pot cover, it is all done manually. Cutting, and finally through grinding wheel grinding, manual production and processing time is long, the efficiency is slow, and the accuracy is not high, and the size of the hole is likely to be inconsistent when drilling, which leads to the inability to match the bolt when the bolt is connected to the pot cover later. , the hole can be reprocessed when the hole is small, and it cannot be used when the hole is large, resulting in an increase in defective products and an increase in cost

At the same time, manual cutting is used, resulting in uneven surface of the pull ring, and at the same time, it is easy to cause damage to the pull ring. Therefore, in mass production, labor can no longer meet the requirements, and it is necessary to use machines instead of manual work. Machining of plates usually uses Stamping
