Plate liquid-filling shaping hydraulic machine

Abstract

The invention discloses a sheet hydraulic-forming hydraulic press which is characterized by essentially comprising an underbeam, an upright post arranged on the underbeam, a top beam arranged on the upright post, a stretching beam connected on the upright post in a sliding manner, a compound master cylinder arranged on the top beam, a coaxial link deep-drawing and blank holding device arranged bellow the stretching beam, a liquid chamber arranged on the underbeam, a support oil tank which comprises a hydraulic power control system, a supercharger, etc. The underbeam, the upright post and the top beam are connected together by upright post nuts to form a rigid body; the compound master cylinder is essentially composed of a cylinder body fixed on the top beam, a master cylinder piston arranged in the cylinder body, a quick rod bush arranged on the master cylinder piston, a quick rod arranged in the rod bush, an embedded bank holding cylinder piston arranged in a master cylinder piston and flanges arranged at the mouth of the cylinder body; the master cylinder piston is connected with the stretching beam by the flanges; the embedded bank holding cylinder piston is connected with the coaxial link deep-drawing and blank-holding device which is essentially composed of a drawing slide, a blank holding slide which is coaxially connected to the drawing slide and is connected with the embedded bank holding cylinder piston and a male die which is fixed on the drawing slide. Compared with the prior art, the hydraulic press of the invention has the advantages of possessing dies with universality, reducing die cost and shortening production cycle.

Description

technical field [0001] The invention belongs to the technical field of hydraulic machines, in particular to a hydraulic machine for liquid-filled forming of plates. Background technique [0002] Metal sheet forming plays a very important role in metal plastic forming. Traditional sheet metal forming is mainly realized by drawing and stamping of mechanical punches and dies. , often cannot be formed or require multiple processes to form, and the work efficiency is low. Due to the existence of mechanical friction, there are surface defects such as strain on the surface of the part and the mechanical properties are poor. In addition, when the size of the part changes, both the punch and the die need to be replaced, the mold has no versatility, the manufacturing cost of the mold is high, and the production cycle is long. Invention content: [0003] The present invention provides a hydraulic press for liquid-filled forming of plates to solve the above-mentioned technical probl...
