Ensuring the accuracy and stability of stamping dies is a key link in stamping production. The following are some specific measures and methods:1. Measures to ensure the accuracy of stamping diesHigh-quality material selection:Select high-strength, wear-resistant, and high-temperature resistant mold materials, such as alloy steel, cemented carbide, etc. These materials can effectively resist the high pressure and frequent use during the stamping process, thereby improving the durability and accuracy of the mold.Optimize mold design:In the design stage, through reasonable mold structure design and gap design, reduce stress concentration points and improve the overall rigidity and stability of the mold.Reasonably set the product's gate, cooling system, etc. to control the consistency and accuracy of the product.High-precision processing:Use high-precision processing equipment and processes, such as CNC machining centers, EDM, etc., to ensure the dimensional accuracy and surface quality of the mold.Strictly control processing parameters, such as cutting speed, feed rate, cutting fluid use, etc., to reduce processing errors and surface roughness.Strict mold inspection:Use high-precision inspection equipment, such as three-coordinate measuring machines, projectors, etc., to inspect the size and shape of the mold.For key dimensions, multiple tests are performed to ensure their accuracy and consistency.2. Measures to ensure the stability of stamping diesStrengthen material processing technology:Heat treatment of mold materials, such as high temperature treatment, to optimize their weldability, toughness, plasticity and hardness.Perform surface treatment, such as grinding, spraying, liquid nitrogen treatment, etc., to improve the wear resistance, corrosion resistance and oxidation resistance of the mold.Reasonable maintenance and maintenance:Regularly maintain, clean and lubricate the mold to reduce wear and friction.Carefully check the mold before processing to ensure that there are no worn parts and fractures.Store the mold in a dry, breathable, non-corrosive gas environment to avoid too high or too low temperature environment.Correct use and operation:The operator should be familiar with the structure and use of the mold and operate it strictly in accordance with the regulations.Avoid damage to the mold caused by overload and improper operation.Use advanced simulation analysis software:Such as AutoFormTM-Sigma, etc., to analyze and optimize process stability and production stability.Through simulation analysis, we evaluate the dangerous and sensitive areas in the process plan, determine the factors that have the greatest impact on product quality, and optimize the process plan to ensure stable production.By selecting appropriate materials, optimizing structural design, precise processing, strict testing, strengthening material processing technology, reasonable care and maintenance, and correct use and operation, we can ensure the accuracy and stability of stamping dies and improve the quality and efficiency of stamping production.
