It is widely used in various industries. In order to meet the use requirements, the quality control of metal stamping parts is more strict. Precision metal stamping parts are processed by stamping, bending, stretching and other means, with high precision stamping. What are the quality policies for precision machining of hardware?
Hardware parts processing
1、 Hardware processing quality policy:
1. Fine principle
The number of processing procedures for bending metal stamping parts mainly depends on the disorder degree of its structural shape, which depends on the number of bending angles, relative direction and bending direction.
2. Exquisite principle
When the metal stamping parts are processed and the section quality and standard precision are required to be high, the fine blanking process can be selected after the blanking process by adding the finishing process or diameter.
3. Principle of accuracy
When blanking workpieces with simple shapes, a single process die can be used. When blanking workpieces with disordered shapes, due to the limitation of the structural strength of the die, the table concludes that blanking should be divided into several parts, and multiple metal stamping processes should be used. If necessary, continuous die can be used. For workpieces with high flatness requirements, a leveling process can be added after the blanking process to accurately apply the characteristics of each product to the production process.
4. Precision principle
The number of processes for processing deep drawn metal stamping parts is related to the material property, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions, and can only be recognized after the calculation of drawing process.
5. Principle of high-quality products
In order to ensure the processing quality of metal stamping parts and the stability of the processing technology of metal stamping parts, it is sometimes necessary to increase the number of processes, such as the punching of additional positioning holes for bending parts, and the addition of deformation reduction hole punching transfer deformation area in the forming process, so as to ensure that each product is fine, delicate and exquisite.
Precision hardware refers to the hardware processing category with high precision requirements in the hardware industry. It is a subdivision of the general hardware industry, and generally refers to the hardware workpieces with precision requirements within 0.05mm.

2、 The characteristics of hardware precision processing industry are:
1. Due to the cold hardening effect, the surface hardness and strength of the precision metal punching surface are greatly improved, and the friction resistance and weather resistance are improved. The service life of precision punches used as moving surfaces, friction surfaces, gears, shaft sleeves and other precision punches will be greatly improved.
2. Precision hardware processing can be made into high-precision hardware accessories in triangle, polygon, trapezoid and other shapes, and stamping parts with high size and form and position accuracy can have straight and smooth stamping surface.
3. Precise hardware processing from raw materials out of finished parts, no longer cutting, high efficiency.
In fact, among these precision hardware, only a few daily hardware products (accessories) are essential tool consumer goods in people's life.
