What are the advantages of the metal stamping manufacturing process?

At present, the metal stamping manufacturing process has become an important part of the parts manufacturing industry, and most stamping hardware parts are used in aerospace, automobiles, ships, machinery, chemicals and other fields. So what are the advantages of the metal stamping manufacturing process? For the metal stamping manufacturing process as a whole, the stamping process is mainly affected by three factors: equipment type, workpiece material, and oil performance. This article will specifically introduce to you: 1. The process advantages of metal stamping 1. Metal stamping parts are costly in data Under the premise of not much, the parts manufactured by stamping have light weight and good rigidity, and after the sheet metal is plastically deformed, the internal arrangement of the metal is improved, so that the strength of the stamping parts is increased. 2. The metal stamping parts have high dimensional accuracy, which is uniform and common with the mold parts, and has good interchangeability. No further machining is required to satisfy general device and application requirements. 3. During the stamping process, because the appearance of the material is not damaged, it has a good appearance quality, and the appearance is lubricated and beautiful, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments. 2. Material selection for metal stamping There are three main stamping processes: punching, bending, and stretching. Different processes have different requirements for the plate. The selection of materials should also be based on the general shape of the product and the processing technology. The selection of the plate should be considered. 1. Blanking requires that the plate should have enough plasticity to ensure that the plate does not crack during punching. Soft materials have good punching performance. After punching, parts with smooth cross-sections and small inclination can be obtained; hard materials have poor quality after punching and have large cross-sectional unevenness, which is especially serious for thick plates. For brittle materials, tearing is easy to occur after punching, especially when the width is small. 2. The plate that needs to be bent and formed should have sufficient plasticity and a lower yield limit. Sheets with high plasticity are not easy to crack when bent. Sheets with lower yield limit and lower modulus of elasticity have small rebound deformation after bending, and it is easy to obtain a curved shape with accurate dimensions. The brittle material must have a large relative bending radius when bending, otherwise it is easy to crack during the bending process. 3. Sheet metal drawing, especially deep drawing, is one of the more difficult sheet metal processing techniques. Not only the drawing depth is required to be as small as possible, the shape is as simple as possible, and the transition is smooth, but also the material has good plasticity. , Otherwise it is very easy to cause overall distortion of the parts, partial wrinkles, and even stretched parts to crack. 3. The selection of metal stamping oils. Stamping oil plays a key role in the stamping process. Good cooling performance and extreme pressure wear resistance have made a qualitative leap in the service life of the mold and the improvement of the accuracy of the workpiece. Depending on the material of the workpiece, the performance focus of the stamping oil is different when it is selected. 1. Silicon steel plate is a material that is relatively easy to punch. Generally, for the cleaning of the workpiece, low-viscosity punching oil is used on the premise of preventing punching burrs. 2. When selecting stamping oil for carbon steel plates, the best viscosity should be determined according to the difficulty of the process, the method of drawing oil and degreasing. 3. The galvanized steel sheet chemically reacts with chlorine-based additives, so when choosing stamping oil for galvanized steel sheet, attention should be paid to the problem of white rust that may occur in chlorine-based stamping oil. 4. Stainless steel plate is a material that is prone to hardening. It requires the use of high oil film strength and anti-sintering tensile oil. Generally, stamping oil containing sulfur and chlorine compound additives is used to avoid problems such as burrs and cracks on the workpiece while ensuring the extreme pressure performance. The above is the introduction of what are the advantages of the metal stamping manufacturing process? With the rapid development of precision stamping technology, small stamping workpieces can meet the needs of various types of machine tool equipment, electrical appliances, instrumentation and other manufacturing industries.
