1、中文 4411 字英文资料Modern Mold Manufacture And Development Of Cutting-edge TechnologyMaterials based on the role of mold in different ways, can be summed up modern processing methods for mold removal method, molding method and the cumulative three types of law. Removal Act - mold material was removed and
2、the necessary forms; forming method - the same total amount of material through the flow of materials and get the body; cumulative law - by the material continue to increase, the accumulated the necessary physical . 1.1 Removal of Mold Processing This is the largest mold maker for a class of methods
3、, including machining, EDM (EDM, wire cutting, electrolytic, etc.), chemical processing, such as corrosion. Characterized by the shape-size components is removed from the blank material to be redundant. 1.1.1 Machining About 90% of the mold by milling, turning, grinding and other machining methods.
4、They are mainly used to mold parts of the final processing aids, as well as working parts of the pre-mold processing and final processing. (1) high-speed machining and milling technology Because the mold cavity often with a large number of free-form surfaces, the traditional hand-made has been unabl
5、e to meet the needs of the linkage of the three-axis or multi-axis CNC milling machine can solve the maximum extent of the problem in this regard. Therefore, CNC milling and programming tool also naturally become the focus of advanced manufacturing technology. (2) die cutting and multi-axis joint co
6、ordinate processing mode Forming the work surface grinding is a traditional method of finishing with a high-precision, high-performance advantages of degrees. In the mold manufacture, die cut shape is mainly used Ruled Surface finishing punch, die pieces and EDM electrodes and other components used.
7、 (3) The mold and polishing After surface machining, surface roughness, regardless of their size must be polished again. Mold Polishing Mold current research is still mainly manually or with electric or pneumatic equipment, manually polished, low efficiency, labor intensity, and the quality of insta
8、bility. China has imported three-dimensional surface can be automatic die polishing of the NC Institute mold. Developed humanoid intelligent automatic polishing technology has also been made, but fewer applications. Mold the future research will be towards the special mode, the composite, automation
9、, intelligent direction. Extrusion die, such as research, study mode and laser polishing, EDM polishing, electrochemical polishing, as well as ultrasonic polishing compound polishing equipment and technology. 1.1.2 EDMMold processing technology of electricity mainly refers to wire cutting, EDM, pier
10、cing and electrolysis processing. (1) WEDM Cutting EDM spark discharge using metal melting or vaporization, and melting or vaporization of the metal to get rid of in order to achieve a variety of shapes metal parts processing. Wire-cutting for processing small precision, complex shapes, materials, s
11、pecial die parts, the more complex shapes, small precision dies, carbide dies in particular, its economic effects has become more significant. Micro-EDM and Wire Cutting walking is the main development of hot spots in recent years. (2) Cavity EDM EDM cavity forming a replication process, it is the u
12、se of spark discharge method to copy the shape of tool electrode in the blank mold cavity formed. EDM cavity mold in todays manufacturing industry has been to occupy the position can not be ignored, it can be sintered metal blocks and steel in the conventional methods of processing can not be proces
13、sed or the shape of difficult processing complex, the size of the fine work, the right choice and the use of electrodes enables the cost of mold manufacturing method than conventional low-40%. Japan invented a new EDM method, that is, in the process of adding the right amount of liquid micro-silica
14、powder, or aluminum powder, graphite powder may be, can make many times more than the surface of precision can be improved, the current processing methods corresponding EDM has also been commercialized. EDM technology can not be separated from the next three trends, namely, high-speed and high preci
15、sion and high automation. (3) Electrochemical Machining ECM is based on the principle of electrolysis (the electrochemical anodic dissolution) will be the shape of the cathode tool for copying onto blank in the mold cavity of mold processing. As soon as the anode and cathode parts of the forming too
16、l insert electrolyte, the effect of current, between the anode and cathode exchange of charge and materials, the result of dissolution of workpiece. In this way, can also be part of the surface area covered by the protection layer, only to other parts of the place of the oxide part of the material. 1.1.3 Die CAD / CAE / CAM (1) mold software integration, intelligent Mold software integrated software modules require relatively complete, while the function module using the same da
