Abstract

The invention discloses a combined oil press with a stander shared by punching and stretching, solving the problems of long blank transmission distance among all working procedures and high heat loss in the prior art. The combined oil press comprises a stander (2), a main working cylinder (1), a punching beam (3), a guiding device, a punching mould base (6), a limiting mechanism (7) and a punching worktable (8), wherein the stander (2) is a box body formed by welding steel plates, is designed into a box type integrally-welded structure and uses high-quality structural steel plates; the structure of the stander is optimized through 3-D finite element calculation; a stretching rod installing base (5) is fixed on the upper part of the outer side face of a left box plate (20), and a stretching cylinder installing base (10) is fixed on the lower part of the outer side face of the left box plate (20); a stretching slide block (11) is arranged on the stretching cylinder installing base (10);and the stretching rod installing base (5) is provided with a stretching rod (12). By the invention, the procedures of compression, punching and stretching can be completed on one press.

Description

technical field [0001] The invention relates to a mechanical punching and drawing device, in particular to a device for punching and drawing a metal blank. Background technique [0002] The production of metal cups in the prior art is all done by punching and drawing, that is, after the steel billet heated to a certain temperature is dephosphorized and calibrated, the billet is first processed into an inner diameter and a bottom thickness that meet The required bottomed cylindrical part is then machined on its outer diameter by drawing process. The current production of special cup-shaped parts in China is completed by pressing, punching and drawing on different presses. The entire production line occupies a large area, and the transmission distance of the blank between various processes is long. During the transmission of time, the heat loss is large and the product precision is low, which is not conducive to the realization and improvement of the automation degree of the ...
