Sheet metal processing process refers to the production process, according to a certain order gradually change the shape of the parts, size, material properties or assembly welding, until the requirements of the plate, shape and size requirements.

sheet metal processingProcess refers to the production process, according to a certain order gradually change the shape of the parts, size, material properties or assembly welding, until the requirements of the plate, shape and size requirements of manufacturing. The whole process of metal processing, for more complex structural parts, its production and processing generally need to go through multiple processes such as material preparation, expansion, cutting blanks, forming and assembly, and because cold-worked sheet metal processing is often combined with welding, metal cutting, heat treatment and Inspection and other processes to form a complete product manufacturing process.
sheet metal processingWork content and process flow
Process flow is an important technical document that guides the entire part processing process, production and processing organization and management. For parts processing that is not completed in a workshop or even a factory, it is an important basis for process flow, division of labor and coordination among workshops.
Since the process flow is the entire prescribed route of each part of the part from the raw material to the entire part, it is also called the process route.
The process flow specifies the processing flow of the parts, and the specific processing content is guided and controlled by the process regulations.
Process specifications are several possible process plans and comprehensives developed by process technicians based on the requirements of product drawings, the characteristics of workpieces, production batches, and the company's existing equipment and production capacity. After analysis and comparison, the technical feasible and economically reasonable optimization process scheme is selected, which is the technical document to guide the production process of parts. In the technical documents, the blank used for the part, its processing method, and the specific processing size; The nature, quantity, sequence and quality requirements of each process; The model and specification of the equipment used in each process; The form of processing tools used in each process (such as auxiliary tools, tools, molds, etc.); The quality requirements and inspection methods of each process. Generally speaking, for large and complex sheet metal structures, sheet metal workers often need to be completed with the cooperation of welders, cranes and other professional types of work, and sheet metal parts are directly processed by pressure processing (such as presses, hydraulic presses, etc.) The processing technology is usually called the stamping process; for the processing technology that uses welded assembly parts, it is usually called the welding process. When the assembly process requires both mechanical processing and welding, riveting and other processing technologies, it is directly referred to as the assembly process or riveting process.
It should be noted that the process is not static and needs to be continuously improved and perfected in production practice. For different enterprises, different production conditions, and even different technical levels of operators, its rationality is also different. However, the general principle is that the formulation of process regulations should ensure the advanced technology, process feasibility and economic rationality, while maintaining good working conditions.
