Description

Forming process of drawer type linear slide rail

technical field

The invention relates to a forming process of a drawer type linear slide rail.

Background technique

A plurality of linear slide rails are arranged in the refrigerator to facilitate the pushing and pulling of the glass plate and the drawer in the refrigerator. Linear slide rails are processed by steel strips through rolling, straightening, stamping and cutting processes. The production line includes unwinding mechanism, feeding guide system, rolling system, straightening system and stamping processing system. The strip-shaped steel strip is unrolled by the unwinding mechanism, and enters the rolling system through the feeding guide system, and the rolled steel strip enters the straightening system, and then enters the stamping processing system after straightening. In the process of processing, both sides of the straight sheet need to be folded to form a groove structure. Multiple arc-shaped grooves are also arranged on each side of both sides of the slide rail.

In the prior art, the bending machine is used to bend both sides of the plate, and the two sides of the slide rail are folded to form a groove structure, and then the two sides of the groove structure are processed, and each side is It needs to be processed many times to form multiple arc grooves. In this processing method, it is formed step by step by several workers using several bending machines. The first step is to form the outer groove, and the second step is to bend the second step on the basis of the mold that is suitable for the formed outer groove. Groove, the third step is to form the third groove on the basis of the mold that is suitable for the second groove, the fourth step is to form the fourth groove on the basis of the mold that is suitable for the third groove, and so on... .........The more complex the groove type, the more bending machines are required. Not only is the cycle slow, the efficiency is low, and a large number of workers are required. The dependence on their operating proficiency is also high, and the processing quality will vary. There are also great hidden dangers in safety. The number of work-related accidents that occur on the bending bed every year is still high, which reduces the safety, production efficiency and processing quality of the entire production system.
