Among these two processing methods, the former has complicated process and many steps in the processing and molding, and will cause a lot of waste of raw materials, while the latter needs to make molds. For some special-shaped structures with more bending, the sprue More, resulting in higher production costs, long production cycle, and in the process of grinding and polishing, it is easy to cause damage to the parts

The invention discloses a phase-change composite forming device for a special-shaped part. The phase-change composite forming device for the special-shaped part comprises a composite punch and a die assembly, wherein a model groove is formed in the die assembly, a straight wall section and a special-shaped section difficult to carry out rigid stamping machining are arranged in the model groove, the composite punch comprises a rigid body and a low-melting-point alloy, and a plate blank is arranged on the die assembly; and the low-melting-point alloy is used for carrying out stamping forming on the special-shaped section of the plate blank, and a heater is further arranged in the die assembly and used for semi-liquefying the low-melting-point alloy. The invention further discloses a machining method of the phase-change composite forming device for the special-shaped part. The temperature of the die assembly is controlled to be 120 DEG C or below, the composite punch is pressed downwards, the plate blank is formed on the straight wall section, the temperature t of the die assembly is controlled to be greater than or equal to 135 DEG C and less than 175 DEG C, and the special-shaped section is integrally formed. According to the phase-change composite forming device for the special-shaped part, and the machining method, the shell body part with a special-shaped structure can be formed in a machining mode of stamping a metal plate.
Description
technical field [0001] The invention belongs to the field of stamping processing equipment, in particular to a phase-change composite molding device and processing method for special-shaped parts. Background technique [0002] Due to structural or aesthetic needs, some shell parts will be designed with special-shaped structures during the design process. In traditional processing technology, these special-shaped structures are difficult to form by stamping, and often require lathes, cutting machines, bending machines, and welding. Machines and other equipment need to be processed multiple times before it can be formed, or it can be formed by pouring through a mold and then grinding and polishing the surface. Among these two processing methods, the former has complicated process and many steps in the processing and molding, and will cause a lot of waste of raw materials, while the latter needs to make molds. For some special-shaped structures with more bending, the sprue Mor...
