2.钣金加工最重要的三个步骤是剪、冲/切、折.1）材料会被送到数控冲床/切割机,进行冲孔/切割工序.在此工序,需要为被加工的零件编制NC(Numerical Control )代码.现在大多数机床厂商都会提供自动编程软件(国内的厂商几乎都是跟国外的此类软件公司合作,进行OEM销售,因此它们并没有自己的软件研发队伍),因此极大地方便了编程工程师.冲压/切割编程工程师所要考虑的因素是板材利用率、刀具、效率、精度等问题.冲压/切割完成后,零件便被去除微连接,接着将被送到折弯机折弯.
The plate gold processing is what, so now by the sheet metal processing manufacturers to give you a detailed description of the main points of sheet metal processing: 1. why the sheet metal industry will develop rapidly. This is mainly the following reasons.1) processing precision requirements low, easy to handle. For gold processing, precision in several silk is very common, and the complexity of the process. It is also high, and even some parts have reached dozens of processes. So the gold processing enterprise usually needs a variety of mechanical equipment to meet the different process requirements. The precision of the sheet metal punching is usually about + 0.1mm, and the bending precision can generally reach to + 0.5mm, so the precision is much lower than that of gold processing.
2) high profit. For example, stamping can reach about 30%, and laser cutting can achieve 50% or more.
3) the demand for production capacity is increasing. China has become more and more international manufacturing center. With the increase of foreign investment, the demand for metal processing capacity 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 also increasing.
2. the most important three steps of sheet metal processing are cutting, punching / cutting, folding.1) materials will be sent to the CNC punch / cutting machine to carry out the punching / cutting process. In this process, the NC (Numerical Control) code is required for the parts to be processed. Now most machine makers will provide automatic programming software (domestic manufacturers are almost all the countries with the country. Such software companies are co operating with OEM sales, so they don't have their own software R & D teams, so it's a great place to have a programming engineer. The stamping / cutting programming engineers have to consider the factors such as board utilization, cutting tools, efficiency, precision and so on. After the stamping / cutting is completed, the parts are removed and then microconnected, then the parts are removed. It will be bent to the bending machine.
2) in the bending process, the main consideration is the choice of cutting tools, bending order, bending compensation, bending interference and so on. Usually there will be random sales of bending programming software, but most of the CNC bending machines in China are still artificial, too often rely on the experience of the teachers, on the other hand, the domestic manufacturing process requirements are relative to the foreign countries. It is said that there is still a certain distance, so the efficiency has not been improved, and the performance of CNC bending machine has not been extremely high.
3) the working process is carried out. Usually, the worksite workers will be cut from the large plate to get the appropriate size of the material according to the expansion drawing provided by the technical department. If the punch, the dead zone of the clamp must be taken into consideration. After the blanking is finished, the worker will mark the material with the marker pen on the surface of each material. Some factories do not have this processing step, directly typesetting on standard sheets, and then directly stamping / cutting.
