High-temperature thermoforming hydraulic machine with adjustable guide devices

Abstract

The invention relates to a high-temperature thermoforming hydraulic machine with adjustable guide devices. The high-temperature thermoforming hydraulic machine with the adjustable guide devices comprises an upper cross beam, a supporting post and a lower cross beam which are connected through a pull rod and a lock nut and are pre-tightened through a hydraulic pre-tightening mechanism to form an overall framework machine body; a main cylinder of which one end is connected with a sliding block is mounted on the upper cross beam; a mobile worktable is mounted on the lower cross beam; the high-temperature thermoforming hydraulic machine with the adjustable guide device is characterized in that a guide sleeve is arranged in the upper cross beam; a guide post of which one end penetrates through the guide sleeve of the upper cross beam is fixed to the upper plane of the sliding block; a plurality of groups of adjustable guide devices are arranged between the axial direction of the guide post and the guide sleeve. The high-temperature thermoforming hydraulic machine with the adjustable guide devices has the advantages that when the gap between sliding wedge iron of each guide device and the guide post is increased, the gap between the sliding wedge iron and the guide post can be adjusted by adjusting the thickness of an adjustment gasket of the corresponding guide device without replacing a guide sleeve part. The operation can be simplified; the production cost can be reduced; the energy resources can be saved; moreover, the forging requirements of various types of workpieces can also be met; the forging quality and the production efficiency of a titanium alloy component are improved.

Description

Technical field [0001] The invention belongs to the technical field of forging machinery, and particularly relates to a high-temperature thermoforming hydraulic press with an adjustable guide device. Background technique [0002] In recent years, with the development of new generation fighters, helicopters, large aircraft and high-performance engines, the manufacturing of aircraft has put forward requirements for high thrust-to-weight ratio, high reliability, high durability, long life, and low cost. And the requirements of the process have also been continuously improved, and a large number of difficult-to-deform alloys, such as titanium alloys and high-temperature alloy materials have been used. Titanium alloy is the best structural material in the aviation industry due to its light weight, high strength, and good heat and low temperature resistance. At present, large-scale titanium alloy and high-temperature alloy forging forming equipment mainly includes normal-scale forging...

AI Technical Summary

Problems solved by technology

The guide structure of the traditional die forging press and the isothermal precision forging press adopts the guide post and guide sleeve type. Since the above-mentioned presses will wear out during long-term use, the gap between the guide post and the guide sleeve will increase easily, resulting in The overall accuracy of the press changes

When processing aircraft titanium alloy components, the requirements for forging accuracy are very strict. Changes in equipment accuracy will cause the workpiece to fail to meet the design requirements and use requirements, and the finished product rate of the workpiece is relatively low.

At this stage, the above-mentioned defects are overcome by replacing the guide sleeve. Replacing the guide sleeve is not only cumbersome to operate, but also has a certain impact on production efficiency, and increases the production cost of the user.
