Equal-wall thickness curve generatrix part precise molding method

Abstract

The invention discloses an equal-wall-thickness curve generatrix part precise molding method, and belongs to the technical field of precise plastic machining. The method includes the following steps that (1) a machining process is adopted for obtaining a variable-wall-thickness taper blank; (2) a strong cold spinning process is adopted for completing molding of a front part of a part; (3) a strong common heat spinning process is adopted for completing molding of a back part of the part; and (4) according to the drawing requirement, follow-up machining is completed to obtain the part. The spinning method is used for forming the equal-wall-thickness curve generatrix part, and the beneficial effects of being high in product strength, high in accuracy, simple in operation, high in production efficiency and good in product consistency, improving the organization and machine performance of the molded part and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of precise plastic processing, in particular to a precise forming method for equal-wall-thickness curved busbar parts. Background technique [0002] Curved busbar parts are a common part in mechanical manufacturing. With the development of science and technology, their applications are becoming more and more extensive, involving many application fields such as aviation, aerospace, and pressure vessels. [0003] At present, most of the processing and manufacturing methods of curved busbar parts are completed by rolling and welding to obtain the cone and then bulging (sheet metal stamping, internal high pressure, etc.). This process mainly has the following shortcomings: (a) The parts are less strengthened during the processing, The strength of the product is relatively low, especially the weakening of the strength of the weld seam is serious; (b) there is welding stress and welding deformation at the weld sea...

[0003] At present, most of the processing and manufacturing methods of curved busbar parts are completed by rolling and welding to obtain the cone and then bulging (sheet metal stamping, internal high pressure, etc.). This process mainly has the following shortcomings: (a) The parts are less strengthened during the processing, The strength of the product is relatively low, especially the weakening of the strength of the weld seam is serious; (b) there is welding stress and welding deformation at the weld seam, and the product accuracy is low; (c) the inspection of the weld seam is more cumbersome and often becomes the follow-up test and use. Potential risks and hidden dangers; (d) more processes, lower efficiency, and poor product consistency
