A method for installing guide components of a frame-type hydraulic press dedicated to hot-press forging of high-speed rail components

Abstract

The invention relates to an installation method for a frame type hydraulic machine guide assembly special for high-iron part hot press forging. The installation method is characterized in that guide rail abrasion resistant pieces and abrasion resistant pieces of sliding blocks of the frame type hydraulic machine guide assembly are arranged at 45-degree angle, and an adjusting base used for adjusting the gap between the abrasion resistant pieces is composed of a strip-type connecting block A and a strip-type connecting block B, and installed and manufactured through a sectioning method to ensure the installation precision. The installation method has the advantages that guide rails form 45-degree included angles with both longitudinal and transverse face plates of the sliding blocks, and the sliding blocks can bear yawing force in the longitudinal and transverse directions in the moving process, so that the number of the guide rails and the abrasion resistant pieces thereof is reduced while the working condition requirement for the sliding blocks is met. Meanwhile, the adjusting base is manufactured through the sectioning method, the large-size material consumption of the L-shaped adjusting base made through integral cutting can be reduced at first, and the welding deformation of the L-shaped adjusting base during integral welding is avoided, and the phenomenon that the L-shaped adjusting base cannot be corrected after the integral welding is avoided, so that the guide precision is ensured.

Description

technical field [0001] The invention relates to a manufacturing method of a hydraulic press, in particular to a method for installing a guide assembly of a frame-type hydraulic press 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. [0003] In the frame-type hot-press forging special hydraulic press used to manufacture high-speed rail components, it is necessary to set vertic...

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
