The sheet metal processing production process refers to the entire process of making products from raw materials (or semi-finished products). For machine production, it includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly, and debugging, painting and packaging. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, and regard the production process as a production system with inputs and outputs. It can make the management of the enterprise scientific and make the enterprise more adaptable and competitive.In the sheet metal processing and production process, the sheet metal processing factory directly changes the shape, size and performance of the raw material (or blank) to turn it into a finished product, which is called the process. It is the main part of the production process. For example, casting, forging and welding of blanks; heat treatment to change material properties; machining of parts, etc., are all technological processes. The technological process is composed of one or several sequential procedures. In order to process qualified parts, the thickness of the layer of metal that must be cut from the blank is called the machining allowance.Sheet metal processing productsMachining allowance can be divided into process allowance and total allowance. The thickness of the metal layer that needs to be removed in a certain process is called the machining allowance of the process. The total margin that needs to be removed from the blank to the finished product is called the total margin, which is equal to the sum of the margins of each process on the corresponding surface. The purpose of leaving a machining allowance on the workpiece is to remove the machining errors and surface defects left by the previous process, such as the chilled layer, pores, sand layer on the surface of the casting, and the oxide scale, decarburized layer, and surface cracks on the surface of the forging. , The internal stress layer and surface roughness after cutting. Thereby improving the accuracy and surface roughness of sheet metal parts.Sheet metal processing products have the characteristics of light weight, high strength, electrical conductivity, low cost, and good mass production performance. They are widely used in electronic appliances, communications, automotive industry, equipment and other fields, such as computer cases, mobile phones, MP3 In China, sheet metal is an essential part. As the application of sheet metal processing becomes more and more extensive, the requirements for sheet metal processing are getting higher and higher. In fact, the overall requirements for sheet metal processing parts are not very high, but more attention is paid to assembly, but the requirements for sheet metal processing are strictly implemented Tolerance, if the tolerance can be assembled is not qualified, its tolerance requirements are one level higher than normal, so the requirements for sheet metal processing will be more stringent.Because the application fields of sheet metal processing products are very wide, its downstream includes almost all manufacturing industries. The main industries are communication electronics industry, automobile manufacturing, motorcycle manufacturing, aerospace industry, instrumentation industry, home appliance industry, etc. Generally speaking, most of the metal forming parts of various electromechanical products are produced by sheet metal technology. Among them, the stamping process is suitable for mass production, and the CNC sheet metal processing technology is suitable for production. Although my country's sheet metal processing industry has moved to the world and has a market share among many customers in the world, there is still a gap in technical level compared with related companies in developed countries. The key gap lies in the weak technical service capabilities, which cannot be adequate and timely. satisfy customer's request.
