Now tensile machine, rubber tensile testing machine, plastic tensile testing machine, metal universal material testing machine industry, in the production by adding new elements, such as is Bang Rak force machine production on the sheet metal into a lot of innovation.After the reform, we are now using CNC bending sheet metal machines, bending laser cutting, has the advantages of high precision, cutting standard.
Briefly explain what is sheet metal processing and manufacturing technology, sheet metal processing, metal materials, profiles, tubes and semi-finished products, take advantage of the plasticity of the material made from various parts of the processing technology, in the case of not cutting.Sheet metal manufacturing and processing technology is used in the forming process and into the machine and blending process equipment (mold) is closely related.The development of this technology not only to improve the level of sheet metal technology, and sheet metal forming deformation and sheet metal mechanization and automation, reduce the amount of manual labor.The characteristics of sheet metal manufacturing and processing technology is mainly determined by the parts of the structure and mode of production of the products.
Bond sheet metal processing and manufacturing technology are mainly the following aspects of technology:
1, plastic forming technology
Conditions (organization, temperature, stress state, etc.) classified in accordance with the plastic, three types of plastic: plastic fine-grained, transformation plasticity, the other plastic.The most widely used in the actual production of fine crystal plasticity, must satisfy two conditions: In addition to the outside material having equiaxed fine grain structure and excellent thermal stability, deformation temperature T> Tm (Tm for this plastic material melting point temperature, absolute temperature); low strain rate.
2, plastic forming / diffusion bonding combined process
Diffusion bonding standard is defined as follows: the surface is connected insufficient to cause plastic deformation pressure and temperature conditions below the melting point of the workpiece is connected to the contact surface is formed or not formed in the liquid phase state of generating a fixed diffusion connection Methods.With the forming / diffusion the connection combined process of application development, diffusion bonding definition extended to large deformation / diffusion-limited connection method.
3, the laser shock
The laser shock processing technology is an impulse laser beam to impact the metal surface to form a plane wave in the form of a pulse, through the workpiece and at the same time to produce plastic deformation of the material technology.
4, hydroforming technology
Hydraulic capsule the elastic die (or punch), oil pressure transmission medium, sheet metal forming and hydroforming technology on the die (or punch).
