Large-scale semi-solid state die forging hydraulic press

Abstract

The invention relates to large-scale semi-solid die forging hydraulic machine, which comprises frame composed of upper beam, lower beam fixed with liftout attachment, slide block and brace linked by tie bar, plant, power system connected with main and side cylinders both fixed on lower beam, and electric system to control power system; wherein, the piston is arranged in cylinder with hollow plunger and its sleeve; the liftout pad is fixed on piston top; a rotation-proof flange is fixed on piston with guide pole connected with travel digital display, a cylinder outlet flange is fixed on cylinder; the guide sleeve for cylinder outlet is in cylinder; both guidance tape and seal ring are embedded in piston wall; and a seal ring leveler and block drop-proof device of X-shaped are arranged on the machine. This invention has advantages composed of high speed, low power, high efficiency and precision.

Description

technical field [0001] The invention belongs to the technical field of hydraulic presses, in particular to a large semi-solid die forging hydraulic press. Background technique [0002] The currently known large-scale semi-solid die forging hydraulic press consists of a fuselage, a frame platform, a master cylinder, a power system, and an electrical system. Fixed on the beam, the piston rod is connected with the slider, and the machine action is completed by the electrical system to meet the process requirements. It solves the existing problems of hydraulic presses in the past. ①The rapid jacking device of the hydraulic press is provided by the pump, which increases the displacement of the pump and the installed power of the whole machine. ②The hydraulic press does not have a four-corner leveling device, which causes the slider to tilt and the workpiece is unqualified. ③The hydraulic press does not have a slider anti-fall device, and there is a problem of sliding down. ④ U...

AI Technical Summary

Problems solved by technology

②The hydraulic press does not have a four-corner leveling device, which causes the slider to tilt and the workpiece is unqualified

③The hydraulic press does not have a slider anti-fall device, and there is a problem of sliding down

④ Under the condition of high temperature pressing, the thermal deformation of the fuselage will change the clearance of the guide rails and affect the accuracy of the machine. These problems will affect the working performance of the large semi-solid die forging hydraulic press and the product quality of the pressed parts as a whole.
