1. Introduction of hardware
Hardware refers to the gold, silver, copper, iron, tin, the general name of five metal materials, hardware is the mother of industry, the foundation of the national defense, the products produced by hardware materials are usually divided into two major types of hardware and hardware. The hardware refers to steel plate, steel bar, flat iron, universal angle steel, trough iron, I-type iron and all kinds of iron and steel. The hardware is building hardware, white iron, lock type iron nail, iron wire, steel wire mesh, steel wire shear, family hardware, all kinds of things and so on. From the nature and use of hardware, it should be divided into steel material, non iron metal material, mechanical machine parts, transmission equipment, auxiliary things, work things, building hardware, family hardware and so on. Each kind of hardware has different uses and functions, and can be selected according to its own needs.
Two. Introduction of sheet metal
The sheet metal refers to the technology of processing all thick plates. There is an essential difference between metal sheet metal processing and hardware, which is mainly the step of shearing and welding. The hardware includes sheet metal and various sheet metal parts.
Three. What is sheet metal processing
Stamping is the most commonly used method in sheet metal processing. Stamping technology is generally divided into two categories: separation process and forming process.
1, the separation process is in the stamping process to make the stamping parts and the blank along the certain contour lines separated, together with the quality of stamping parts to meet the needs of the section also meet the needs, these needs are the needs of the previous customers.
2, the forming process is to make the plastic deformation of the stamping blank under the condition that it is not damaged, and convert it into the desired shape of the product, and it should also meet the needs of the scale tolerance and so on.
Sheet metal is a comprehensive cold processing technology for metal sheet, which includes scissors, blanking / cutting / compounding, folding, welding, riveting, splicing, molding, etc. Its notable feature is the same part thickness together. In general, the basic equipment includes the shearing machine, the CNC punch press, the plasma and water jet cutting machine, the composite machine, the bending machine and the various auxiliary equipment, such as the uncoiler, the leveler, the deburring machine, the spot welding machine and so on.
