Stamping parts have the characteristics of being thin, uniform, light, and strong compared to castings and forgings. Stamping can produce workpieces with reinforcing ribs, ribs, coils, or flanges that are difficult to manufacture with this familiar diameter, in order to improve their rigidity. Due to the rejection of rough molds, the precision of the workpiece can reach micrometer level, with high accuracy and consistent specifications, and can punch out holes, protrusions, etc. In actual production, process tests similar to the stamping process are commonly used to test the stamping performance of materials, such as deep drawing performance tests, bulging performance tests, etc., to ensure the quality of finished products and high pass rates. The accuracy and structure of the mold directly affect the forming and accuracy of the stamped parts. The cost and lifespan of mold manufacturing are important factors affecting the cost and quality of stamped parts. Mold design and manufacturing require more time, which prolongs the production preparation time for new stamped parts.
Whether the structure and technical specifications of the parts are suitable for stamping processing, and the evaluation of these indicators is called the structural processability of the stamped parts.
1、 Process analysis of stamping parts in Kunshan
Selected material properties; Shape and size requirements, precision of stamped parts; If the difficulty level of stamping is unreasonable, propose improvement suggestions;
2、 Determine the overall process plan
Mainly based on the process requirements of the parts, various stamping and auxiliary processes are combined with the current production conditions to make reasonable arrangements and overall considerations.
3、 Determination of the number and sequence of processes
Based on necessary process calculations and equipment conditions, determine the total number of processes to complete this part and their interrelationships, and determine the process dimensions for each process.
4、 Select the corresponding mold structure form
Determine the optimal mold structure based on production batch size, part accuracy, processing conditions, equipment availability.
