Process advantages and manufacturing principles of hardware stamping parts

With the improvement of living standards, hardware stamping parts have penetrated into various fields and are closely related to our lives. Hardware stamping parts are made by stamping process, which is a processing method that uses a die to apply external force to the blank sheet to produce plastic deformation or separation, thereby obtaining a workpiece with certain size, shape, and performance. The stamping and stretching process should be combined with actual conditions such as equipment and personnel to select and design a technically advanced, economically reasonable, and safe and reliable process scheme. The following introduces the process advantages and manufacturing principles of hardware stamping parts:

I. Process Advantages of Hardware Stamping Parts

(1) The assembly and repair of hardware stamping parts are convenient and labor-saving.

(2) The shape of hardware stamping parts is simple and the structure is reasonable, which can facilitate the manufacture of molds.

(3) Hardware stamping parts should make full use of existing materials, equipment, process equipment, and process flow.

(4) Hardware stamping parts can increase the utilization rate of metal materials, reduce the types and specifications of materials.

(5) Hardware stamping parts are conducive to the interchangeability of batch products and reduce scrap conditions.

II. Manufacturing Principles of Hardware Stamping Parts

(1) Precision principle: The number of processes for deep-drawing parts is related to material properties, drawing height, number of drawing steps, drawing diameter, material thickness, etc.

(2) Exquisite principle: The number of processes for bent parts mainly depends on the complexity of their structural shapes, and it needs to be determined according to the number and direction of bends.

(3) Fine principle: When the section quality and standard accuracy requirements of stamped parts are high, it can be considered to add trimming processes after stamping or directly use fine blanking processes.

(4) Accurate principle: For the simple-shaped workpieces, the single-process die can be used to finish, while for the complex-shaped workpieces, due to the limitations of the structure or strength of the mold, its surface and profile should be divided into several parts for stamping, and multiple hardware stamping processes are needed.

(5) Boutique principle: In order to ensure the quality of fine hardware stamping parts, sometimes it is necessary to increase the number of processes. For example, punching holes in bent parts, adding deformation-reducing holes in forming processes to transfer deformation zones, etc., to ensure the level of refinement and delicacy.
