Frame type hydraulic machine guiding structure special for hot press forging of high-speed rail part

Abstract

The invention relates to a frame type hydraulic machine guiding structure special for hot press forging of a high-speed rail part. The frame type hydraulic machine guiding structure comprises a pair of frame type stand columns and a sliding block arranged between the pair of frame type stand columns. The frame type hydraulic machine guiding structure is characterized in that wedge type guide rail assemblies are arranged between the four corners of the sliding blocks and the stand columns on the two sides; and the wedge type guide rail assemblies comprise guide rails, guide rail side wear resistance pieces, adjusting seats, adjusting blocks, sliding block side wear resistance pieces, adjusting block locking screws, wedge-shaped blocks and wedge-shaped block locking screws. The frame type hydraulic machine guiding structure special for hot press forging of the high-speed rail part has the beneficial effects that the included angles of 45 degrees are formed between the guide rails and a longitudinal panel and a transverse panel of the sliding block so that the sliding block can bear longitudinal lateral force and transverse lateral force at the same time in the moving process, the requirement for working conditions of the sliding block is met, and the number of the guide rails and the number of wear resistance blocks can be reduced.

Description

technical field [0001] The invention relates to a hydraulic press, in particular to a frame-type hydraulic press guide structure dedicated to hot press forging of high-speed rail components. Background technique [0002] The slider guide structure of the hydraulic press is used for precise guidance when the slider moves in the frame, and is generally realized by a guide post and guide sleeve structure. However, due to the limitation of the column structure of the frame-type hydraulic machine, the traditional guide column and guide sleeve structure cannot be used. It is generally realized by setting wear-resistant plates on the longitudinal and transverse surfaces of the frame-type column and the slider to meet the bias of the slider under working conditions. carrying capacity.

Problems solved by technology

[0003] In the frame-type hot-press forging special hydraulic press used to manufacture high-speed rail components, it is necessary to set vertical and horizontal wear-resistant plates at the four corners of the slider of this kind of guide structure, and it also needs to be equipped with a gap adjustment mechanism so that after wear Can be adjusted, so the structure is bloated, the manufacturing cost is high, and the maintenance is inconvenient
