Technological Process of Sheet Metal Manufacturing

The technological process of sheet metal manufacturing gradually changes the shape, size, material properties or assembly and welding of parts according to the specified order. After all these steps, the sheet metal parts meet the requirements. For more complex structural parts, the process goes through many steps such as material preparation, unfolding and sample opening, cutting blanks, forming and assembly. In addition, the cold sheet metal processing is often associated with welding, metal cutting, heat treatment and inspection. This is the complete manufacturing process.

 

Generally speaking, the technological process will form a technical document, which is to guide the entire parts processing, organize and manage the whole manufacturing. For the processing of parts that are not completed in a workshop or even a factory, it is an important basis for the production process in each workshop, division of labor and cooperation between factories.

 

Since the process flow is the entire route through which each part in the component is completed from the raw material to the finished product, it is also called the process route.



 

Process specification for sheet metal

 

The technological process determines the processing flow of the parts, while the specific processing content is guided and controlled by the process rules.

 

 

The process specification is based on the requirements of the product drawings, characteristics of the workpiece, production batch, existing equipment and production capacity, etc. After careful comprehensive analysis and comparison of several possible process plans drawn up by the process technicians, pick up a technically feasible and economically reasonable optimal process plan. There is a technical document to guide the production process.

 

The technical document regulates the blank used for the part, processing method, specific processing size, quantity, sequence and quality requirements of each process. It also regulates the equipment model and the processing used in each process. You can also see the form of tools (such as auxiliary tools, knives, molds, etc.), the quality requirements, inspection methods and requirements of each process, etc.

 

Process specifications have different displays in specific applications. Generally speaking, for large and complex parts, sheet metal workers need to cooperate with other types of workers such as electric welders and crane workers to complete it. While sheet metal are directly finished by pressure processing (such as presses, hydraulic presses, etc.) The technology is often called the stamping process.

 

For the processing technology that uses welding for component assembly, it is often called welding technology. For assembly processing that requires both mechanical processing and welding, riveting and other processing technology, it is directly called assembly technology. The process card is most popular among them.

 

The specific format varies, but what is included is roughly the same. It mainly includes the name and model of the product. The name of the part, the grade, specification, number of pieces of the material, sequence number, name and content of the process, the process equipment used to complete each process, etc. are all written on the card.



 

Molds and measuring tools (checking tools, samples) are code-named in the process card. It facilitates the production of molds and measuring tools and meets the needs of technical management.

 

Generally speaking, when it comes to the processing technology of all sheet metal parts, blanking and stamping workshop are not enough. Many parts may also be interspersed with machining, heat treatment, surface treatment, etc.

 

The whole process is controlled by the content of the corresponding process regulations. However, in different industries, especially when processing sheet metal components with low technical requirements and low complexity, it is often possible to compile a comprehensive process specification to guide production.
