A kind of lock tongue production technology based on cold-drawn steel

Abstract

The invention discloses a lock tongue production process based on cold-drawn steel, which belongs to the technical field of lock tongue production. A lock tongue production process based on cold-drawn steel can be used according to the shape of the lock tongue through the use of abnormal molds. The rough product of the lock tongue formed for the first time is set into a more conventional shape, and the redundant part is cut off after forming. Compared with the existing heterosexual mold, this mold can effectively reduce the cost of mold opening, and at the same time, this unusual mold can also be used for The lock tongue provides a fault-tolerant space, which can effectively reduce the range of defects such as trachoma, microcracks, and hollow air bubbles, thereby reducing or eliminating the range that needs to be repaired, and effectively improving the quality of the finished product. The use of printed parts makes the bottom of the rough product of the lock tongue show the mark of the lock hole, which can directly fix the punching position, which provides convenience for the subsequent drilling of the lock hole and effectively improves the production efficiency of the lock tongue.

Description

technical field [0001] The invention relates to the technical field of lock tongue production, and more specifically, relates to a lock tongue production process based on cold-drawn steel. Background technique [0002] Cold-drawn steel is steel of various cross-sectional shapes and sizes processed by cold drawing. Cold-drawn steel is also called cold-drawn steel or cold-drawn steel. Cold-drawn steel can be used as a complete set for the automobile industry, hardware tool industry, machinery processing manufacturing industry, and textile machinery processing manufacturers. Diesel engines, musical instruments, household appliances, office equipment, steel furniture and handicrafts, decorations, lighting industry, hardware decoration industry, instrumentation, electric tools, construction machinery, elevators, fitness equipment, aerospace and other industries.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when cold-drawn steel is used to produce the lock tongue, since the shape of the lock tongue is generally not regular, the mold is relatively complicated when the mold is opened, and the cost of mold opening is very high, and after the lock tongue is formed, it is necessary to When drilling the lock hole, the position of the lock hole needs to be very precise. Once it deviates, the entire lock tongue will be scrapped. Therefore, when opening the hole, it is often necessary to perform complicated drilling and alignment operations, resulting in a decrease in work efficiency. In addition, when molds are used to form the lock tongue, trachoma, microcracks, and hollow air bubbles often appear on the surface of the lock tongue, which can easily lead to the quality of the finished lock tongue, increase the scrap rate, and cause a large degree of waste of material resources.
