Multi-directional die compound extrusion hydraulic press

Abstract

The invention discloses a multidirectional die compound extrusion hydraulic press which comprises a novel combined-type bidirectional prestress bearing rack and a combined-type double-X-type compound guide frame. The combined-type bearing rack comprises a horizontal upper crossbeam, a horizontal lower crossbeam and two vertical vertical upright beams, a vertical working cylinder is arranged in each of the horizontal upper crossbeam and the horizontal lower crossbeam, and each equal-strength vertical upright beam comprises two equal-strength beams which are transversely connected through a sleeve, used for mounting of a horizontal working cylinder and allowed to bear working load in the horizontal direction. The combined-type guide frame comprises two guide bodies, a guide side of each guide body is provided with a protruding portion, first guide faces are symmetrically arranged on two sides of the upper portion of each protruding portion, second guide faces are symmetrically arranged on two sides of the lower portion of each protruding portion, and extending lines of the first guide faces and the second guide faces all pass the center of the combined-type bearing rack. By adopting the combined-type bidirectional prestress bearing rack and the double-X-type compound guide frame, the multidirectional die compound extrusion hydraulic press has bearing capacity and running accuracy which are safe and reliable, and number of control axes of the working cylinders reaches seven, so that wider production process uses are acquired.

Description

technical field [0001] The invention relates to a multi-directional die composite extrusion hydraulic press, in particular to a multi-direction die composite extrusion hydraulic press with a bidirectional prestressed bearing frame. Background technique [0002] The bearing frame is the most important part of the hydraulic machine body, so the bearing frame must have sufficient strength and rigidity to meet the performance requirements and economy of different manufacturing processes. However, in the technical field of hydraulic presses, there is still no major breakthrough in the structural design of the bearing frame of the existing hydraulic presses, which have the same shape, single function, low performance, and limited range of process applications. For example: the vertical bearing frame of the traditional "three beams and four columns" hydraulic press can only bear the working load in the vertical direction. Depending on the application, it is used for vertical formin...

AI Technical Summary

Problems solved by technology

Under the working load, due to the lateral bending deformation of the column, it is easy to deflect the movable beam with a short guiding length, and the guiding accuracy cannot be guaranteed

[0004] The number of working cylinders of the existing multi-directional die forging hydraulic presses is generally 3-5 axes, and the horizontal working cylinders are all single-axis, and the capacity is relatively low, and the weight of the formed product is small, and only a single horizontal split molding can be performed. The process application range of multi-directional die forging
