The first mock exam of the first mock exam is that the metal stamping parts of the metal stamping parts are generally required for high productivity and multi cavity. The large mold can reach hundreds of chambers and thousands of chambers. The hardness of die steel material processed by hardware die is high, so the die processing equipment must have thermal stability and high reliability. For complex cavity and multi-functional composite mold, with the diversification of the shape of the parts, the design and manufacturing level of the metal stamping parts must be improved.
When the repeated positioning accuracy and linear feed rate of metal stamping parts are used to process the three-dimensional surface of the metal mold, the metal stamping parts can not reflect the actual processing situation of the stamping parts. The high-precision machining of three-dimensional curved surface of mould puts forward the requirement of high dynamic precision performance. High speed and high precision can only be realized with the cooperation of high rigidity, thermal stability, high reliability and high-quality control system of machine tool.
The combination of metal stamping technology and green product technology will be taken into consideration when enterprises purchase equipment. The radiation and medium selection of EDM machine tools will be the factors affecting safety and environmental protection. The EDM milling technology of metal stamping parts will be developed in the future mold processing field. The composite application of various measurement technologies, high-speed measurement and reverse engineering will become the driving force for mold processing Participate in the development trend of product development and design technology.
Metal stamping is a comprehensive cold working process for metal sheet (usually less than 6 mm), including shearing, punching, cutting, laminating, folding, welding, riveting, splicing and post forming. The obvious feature is that the thickness of the same part is the same. That is to process steel plate, aluminum plate, copper plate and other metal plates.
