Abstract

The invention discloses a lock bar iron sharp head processing technology of a lock core. The lock bar iron sharp head processing technology of the lock core performs processing and manufacturing through the processes of material selection, material cutting, preliminary shaping, deep shaping, positioning, hole drawing and shaping, right angle processing, shape fixing, accessory leading, edge slot cutting, outside processing and the like, changes a traditional processing technology, can complete processing of a side hole in a flat surface of a lock bar head directly through a multi-station coldextrusion shaping machine, replaces a traditional processing technology, greatly improves production efficiency and product quality stability, saves production cost, uses cold forging processing partsand accessories according to the continuous improvement speed of the cold forging technology, greatly reduces cost of prior processing methods and raw materials, improves yield and quality, adopts the cold extrusion technology, obtains a product smooth and bright in surface, is small in raw material loss, saves material cost, and saves large amounts of machining time and processing machinery cost.

Description

technical field [0001] The invention belongs to the technical field of processing lock iron sharps for lock cylinders, and more specifically relates to a process for processing lock iron sharps for lock cylinders. Background technique [0002] The deadbolt head is a common hardware part in door locks. A lock is a device commonly used to fasten a door or window. Each built-in lock has a deadbolt head that is retractable and inserted into a metal plate on the door frame to prevent the door from being opened. The expansion and contraction of the latch head is controlled by a cam. When the existing latch head structure is processed and formed, the traditional processing technology needs to consume more raw materials, and the processing cost is high. [0003] In order to change this status quo, we have introduced a processing technology for the lock iron sharp head of the lock cylinder. Contents of the invention [0004] The purpose of the present invention is to solve the s...
