Production process of pressure formed hollow handle of metal plate

Abstract

The invention discloses a production process of a pressure formed hollow handle of a metal plate. The production process is characterized in that the handle consists of a handle lower shell, a handle upper shell and a handle head. The process comprises the following steps that: the hollow handle lower shell and the hollow handle upper shell are formed into a handle with a required shape by applying a pressure to the metal plate through a hardware die; the handle lower shell and the handle upper shell are welded to form a hollow lock handle shell; and the handle head is fixed on a head of the hollow lock handle shell and is fixedly connected in a way of welding or pin riveting. In order to make the product more attractive, the welded product is polished, and then whether the product is to be electroplated and sealed with paint is determined according to needs. The production process has the advantages of easiness in processing, short production period, low cost, attractive appearance, durability, various shapes and styles, good handfeel, light weight, environment friendliness, resource conservation and the like, particularly, the advantages in saving materials and resources are obvious; and the material ratio of a hollow lock to a solid lock with the same style is about 1 to 2, and the material ratio of the hollow lock to solid lock with some style is 1 to 3 or more.

Description

technical field [0001] The invention relates to a lock handle and a lock panel, especially a production process and processing method of a lock panel and a hollow handle of a lock with any shape, pattern and style, and is suitable for brass, stainless steel, and iron with a thickness of 0.3-10.0mm. , zinc alloy, aluminum alloy, magnesium alloy and other metal sheets. 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 and door locks. , drawer locks, car locks, electronic locks, etc., forming ...

AI Technical Summary

Problems solved by technology

Generally, the existing lock handles and panels are mostly solid structures, which are mainly produced by casting methods such as precision casting, pressure casting, forging casting, etc., and have wide applicability, but solid lock handles and panels generally have the following defects: (1) Due to casting: difficult processing, long production cycle, high environmental pollution and high cost; (2) due to solid reasons: more materials, heavy weight, large loss, inconvenient installation

The above reasons seriously restrict product production, resource conservation and environmental protection.
