Horizontal forging press base

Abstract

The invention relates to the field of extrusion presses and discloses a horizontal forging press base. The horizontal forging press base comprises a rack and a fixed support; the rack is formed by fixedly connecting two cross beams and a stand column located between the cross beams through a pre-tightening mechanism, the fixed support is located at the bottom of the first cross beam, and the rackis fixedly connected with the ground through the fixed support; the base further comprises a swing arm support; the swing arm support is arranged at the bottom of the second cross beam; and the swingarm support comprises a bearing seat, a horizontal rotating shaft and a swing arm supporting piece, the top of the bearing seat is fixedly connected with the second cross beam through bolts, a transverse horizontal rotating shaft is arranged in the bearing seat, the top of the swing arm supporting piece is fixedly connected with the horizontal rotating shaft, an arc-shaped plate is fixedly arranged at the bottom of the swing arm supporting piece, the arc-shaped plate and the horizontal rotating shaft are coaxial, and the bottom of the arc-shaped plate is in rolling connection with the ground.Horizontal additional loads generated by telescopic deformation of the rack on the base are eliminated through the rolling connection between the bottom of the arc-shaped plate and the ground, the stability of a machine body is improved when the forging press operates, and the service life of the base is prolonged.

Description

technical field [0001] The invention relates to the field of extruders, in particular to a base of a horizontal forging press. Background technique [0002] In the prior art, forging machine tools are equipment used for metal and mechanical thermal processing. Forging machine tools include plate rolling machines, shearing machines, punching machines, presses, hydraulic presses, hydraulic presses, bending machines, etc. Large forging presses use oil as the The working medium is a kind of equipment that uses different molds to forge under liquid pressure. [0003] During the forging process, the oil cylinder applies a load to push the movable beam to forge the billet, and the resulting reaction force of the oil cylinder acts on the frame of the forging press, causing the frame to stretch and deform. Especially for the horizontal forging press, it is even more serious. The tensile deformation produces a horizontal additional load on the base, and the tensile elongation of th...

AI Technical Summary

Problems solved by technology

Especially for horizontal forging presses, it is even more serious. The tensile deformation produces horizontal additional loads on the base, and the tensile elongation of the frame of the base is relatively large. The traditional installation method of the forging press base cannot absorb the The additional load force generated by the stretching of the frame seriously affects the operation stability of the horizontal forging press during the forging process, affects the quality of forging parts, and also reduces the service life of the horizontal forging press base
