Hollow lock panel and method for manufacturing same

Abstract

The invention discloses a hollow lock panel and a method for manufacturing the same. The method for manufacturing the hollow lock panel includes steps of computing a required plate blank spreading size according to the size of a lock panel shell; manufacturing a drawing die according to the shape of the lock panel shell and manufacturing a cutting die according to a blank spreading mode of the lock panel shell; punching a metal plate on a punching machine by the aid of the cutting die to obtain a blank; machining the blank on a hydraulic forming machine by the aid of the drawing die to obtain an initial blank and holes of the lock panel shell; shaping the initial blank of the lock panel shell on the hydraulic forming machine by the aid of the drawing die by 1-5 times to obtain the lock panel shell with the finally machined shape; fixing a spring stud and a screw stud on the inner surface of the lock panel shell by means of welding; grinding and polishing the outer surface of the lock panel shell, electrically plating the outer surface of the lock panel shell as needed or spraying seal paint on the outer surface of the lock panel shell as needed. A numerical value of the punching pressure of the punching machine ranges from 8 tons to 120 tons. A numerical value of the pressure of the hydraulic forming machine ranges from 80 tons to 1000 tons when the blank is machined on the hydraulic forming machine. A numerical value of the pressure of the hydraulic forming machine ranges from 80 tons to 300 tons when the initial blank is shaped on the hydraulic forming machine. The method is suitable for machining lock panels made of metal plates.

Description

technical field [0001] The invention relates to the field of locks, in particular to a hollow panel of a lock and a manufacturing method thereof. Background technique [0002] Lock products are closely related to people's lives, guaranteeing the stability and prosperity of the society, and are the major exporters of mechanical and electrical products in my country. my country is a big lock-making country in the world, and it has developed rapidly in recent years. At present, there are more than 1,500 lock manufacturing enterprises in my country, mainly concentrated in the five major lock-making bases of Guangdong, Shandong, Zhejiang, Jiangsu and Shanghai, mainly producing padlocks, locks, Drawer locks, car locks, electronic locks, etc., form more than 20 categories, more than 100 series, more than 8,000 designs and specifications. [0003] Generally, the existing lock panels are mostly solid structures, which are mainly produced by casting methods such as precision casting, ...

AI Technical Summary

Problems solved by technology

[0003] Generally, the existing lock panels are mostly solid structures, which are mainly produced by casting methods such as precision casting, pressure casting, forging casting, etc., and are widely used in lock manufacturers, but the solid lock panels generally have the following defects: 1. Due to the Causes: Difficult processing, long production cycle, high environmental pollution, high cost; 2. Due to solid reasons: more materials, heavy weight, large loss, inconvenient installation

The above reasons seriously restrict the production efficiency of products, which is not conducive to resource conservation and environmental protection, so it is necessary to develop a new processing method
