To put it simply, our sheet metal processing is closely related to daily life.
What are the types of sheet metal processing and manufacturing technology? Why is the sheet metal processing industry developing so well? Sheet metal processing, in simple terms, it is a processing technology, is the use of the plasticity of the material, it is processed into various parts of the process, so it has the term sheet metal manufacturing technology. Do we know all about its species? The little editor feels that the answer is negative. Underneath, to this problem, start a specific discussion, so that you can understand some of its main types, so that we can understand and deepen the sheet metal processing this product.
The main types of sheet metal manufacturing technology are:
(1) hydroforming technology
That is, the hydraulic bag is used as an elastic concave die or punch, and oil is used as a pressure transmitting medium, thereby forming operation and process.
(2) laser shock technology
That is, the laser beam is pulsed through the form of metal to form a plane wave, which can cause plastic deformation of the material.
(3) plastic forming technology
It can also be divided into three kinds, which are fine grain plastic, phase change plasticity and other plasticity. The most widely used is the first kind, but it has some requirements. The main is that the microstructure of the equiaxed fine crystal should have good thermal stability, the deformation temperature should be greater than the melting point temperature of the material, and the rate of the device should be low.
Sheet metal processing is closely related to the life of our life, almost all of the manufacturing industry can not be separated from sheet metal processing. In general, the sheet metal processing industry has developed rapidly in recent years. The main reasons are the following aspects.
1, sheet metal processing profit is high. For example, stamping can reach about 30%, and laser cutting can achieve 50% or more.
2, the production capacity demand of sheet metal processing is improved. China has become more and more international manufacturing center. With the increase of foreign investment, the demand for metal finishing is increasing, and the electrical control box and machine shell in the metal processing industry are generally sheet metal parts, so the demand for the processing capacity of metal sheet metal is not broken.
3, sheet metal processing accuracy is low, easy to get started. As far as sheet metal processing is concerned, accuracy is very common in several threads, and the complexity of the process is relatively high. Even some parts work in dozens of ways. Therefore, gold processing enterprises usually need a variety of mechanical equipment to meet different technological requirements. The punching accuracy of sheet metal is usually about 0.1mm, and the bending accuracy can reach 0.5mm. Therefore, the accuracy is much lower than that of gold processing.
