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.
