Accuracy adjusting device for isothermal thermal forming hydraulic machine

Abstract

The invention discloses an accuracy adjusting device for an isothermal thermal forming hydraulic machine. The isothermal thermal forming hydraulic machine comprises four guide columns fixed to a sliding block, and is characterized in that the cross section of each guide column is square; upper transverse beams are disposed on the guide columns; positioning sleeves are disposed between the upper transverse beams and the corresponding guide columns; each positioning sleeve is of a Z-shaped structure with the 90-degree corners; one end of each positioning sleeve is transversely arranged on the corresponding upper transverse beam; adjusting pads are put on the transversely arranged surfaces of the positioning sleeves; the end faces of the other ends of the positioning sleeves make contact with the guide columns; sliding wedges and fixed wedges which are equal in slant angle are disposed in gaps between the positioning sleeves and the guide columns; the slopes of the sliding wedges and the slopes of the fixed wedges are in close contact; the fixed wedges are fixedly connected with the positioning sleeves; a board is connected to the tail of each sliding wedge; the adjusting pads are located between the boards and the transversely arranged surfaces of the positioning sleeves; the boards, the adjusting pads and the positioning sleeves are connected through double-threaded screws.

Description

technical field [0001] The invention belongs to the technical field of hydraulic presses, and in particular relates to an accuracy adjustment device for isothermal thermoforming hydraulic presses. Background technique [0002] At present, with the development of the aerospace industry, there is a bottleneck in the manufacturing equipment capacity of the aircraft titanium alloy tail section, which is mainly manifested in the maintenance of forging temperature and the adjustment of the precision of forging presses at high temperatures. In the forging process of high-temperature hot forming of aircraft titanium alloy components, the requirements for forging temperature are relatively strict, that is, the forging temperature should be kept within a temperature range of about 900 °C. The traditional equipment guide structure adopts the guide column and guide sleeve type, which mainly refers to setting four guide sleeves on the slider. The guide sleeves are equipped with dust-proo...

AI Technical Summary

Problems solved by technology

Aircraft titanium alloy components have very strict requirements on forging precision. Changes in equipment precision will cause the workpiece to fail to meet the design requirements and use requirements, and the yield of the workpiece is relatively low.
