Die and method for forming thin-walled cylinder-shaped part into rectangular part

Abstract

The invention belongs to the technical field of part machining, and particularly relates to a die and method for forming a thin-walled cylinder-shaped part into a rectangular part. The die comprises aworkbench and a die base, the die base is fixedly connected to the center of the upper end of the workbench, vertical supporting columns are fixedly connected to the four corners of the lower end ofthe workbench, the lower ends of the supporting columns are fixedly connected with bases in contact with the ground, a round groove for containing a cylinder-shaped part is formed in the upper end ofthe die base, a die ejecting mechanism for ejecting the part out is arranged at the lower end of the workbench, the die ejecting mechanism correspondingly extends into the round groove, an extension plate is fixedly connected to the side wall of the workbench, and the upper end of the extension plate is fixedly connected with an L-shaped bracket. The die and method have the advantages that under the use of single energy supply equipment, the forming operation of multiple extrusion forming mechanisms on parts can be realized, the energy loss is relatively reduced, the machining quality of the parts can be ensured by adopting a rigid structure, and the situation that the parts are unqualified due to the change of elasticity is avoided.

Description

technical field [0001] The invention relates to the technical field of part processing, in particular to a mold for forming a thin-walled cylindrical part into a rectangular part. Background technique [0002] The 056 housing is a functional part on the hermetic switch, and its material is 0.25 mm thick stainless steel. The size of the inner hole of the 056 shell must be guaranteed, the parts cannot be deformed, and the surface cannot be scratched or scratched. The original processing technology is to use a CNC lathe to turn the stainless steel bar into a cylindrical blank, and use two sets of rolling fixtures to press the cylinder on the handle press. Shaped blanks are rolled into 056 shell parts. [0003] After retrieval, Chinese Patent Publication No. CN110153286B provides "a thin-walled cylindrical part formed into a rectangular part mold, including a mold handle, a forming punch, left and right slider inserts, and a push block; the lower end of the mold handle has an u...

Problems solved by technology

In the above-mentioned technology, when the parts are stamped, they rely on elastic structures such as springs, so that there are differences in the processing of the parts, because the elastic structure will affect the accuracy of the parts due to the change of elasticity after long-term use, and the qualified use of the parts cannot be guaranteed.
