A lock hot stamping process

Abstract

The invention belongs to the field of machining and manufacturing, and particularly relates to a hot punching process for a lock catch. The hot punching process adopts a lock catch hot punching die, wherein the lock catch hot punching die comprises a telescopic cylinder, a punch pin module, a lower die, a clamping module and an ejection module, the punch pin module is installed on the telescopic cylinder, and the punch pin module is used for punching blank to form the lock catch; the lower die is located below the punch pin module, a lock catch hole is formed in the middle of the lower die, and the lower die is used for being matched with the punch pin module to punch the blank to form the lock catch; the clamping module is installed on the lower die, and the clamping module is used for clamping the blank when the blank is punched; and the ejection module is installed in the lower die, and the ejection module is used for ejecting the lock catch formed by punching out of the lower die.The lock catch hot punching die is mainly used for hot punching forming of the lock catch, can be used for punching a three-grooved lock catch, and can also be used for punching a six-grooved lock catch; and when the lock catch hot punching die is used for punching different types of lock catches, a punch pin is not required to be replaced, and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of mechanical processing and manufacturing, and specifically relates to a locking hot stamping process. Background technique [0002] The lock is a buckle-type fastener used in mechanical equipment, as attached image 3 , attached Figure 4 The structural diagram of the lock shown shows that the lock is a hexagonal structure with a circular through hole in the middle and six or three grooves evenly distributed along the circumference of the circular through hole. Casting is used for forming. It is necessary to heat the metal material to melt it into a liquid state, then cast the liquid metal into a mold to form a blank, and then perform a series of subsequent processing such as cutting, grinding, and heat treatment on the blank to make the product. The precision and strength meet the requirements of use. This method requires multi-process processing and cannot be formed at one time. The processing is cumbersome and t...
