High-precision hydraulic press

Abstract

The invention discloses a high-precision hydraulic press and belongs to the field of hydraulic forming devices. The high-precision hydraulic press comprises guide columns and a guide plate capable of operating along the guide columns. A guide sleeve is installed between each guide column and the guide plate. Each guide sleeve comprises a fixedly arranged outer sleeve body and an inner sleeve body movably arranged in the outer sleeve body, wherein the outer sleeve body and the inner sleeve body are in wedge-shaped fit. Each inner sleeve body moves along the inner inclined face of the corresponding outer sleeve body. Each guide column is sleeved with the inner sleeve body. Each annular outer sleeve body is fixed into the support. Each support is connected with the guide plate through bolts. The guide plate enables the inner sleeve bodies to be pressed into the outer sleeve bodies. Springs are arranged between the bolts and the guide plate. Through mutual cooperation between each fixed outer sleeve body and the corresponding movable inner sleeve body, it is guaranteed that each inner sleeve body can slide between the corresponding outer sleeve body and the corresponding guide column. When the inner side face of each inner sleeve body and the corresponding guide column are worn, under the action of the corresponding spring, the inner sleeve body is automatically pushed into the corresponding outer sleeve body, and it is avoided that the wear between the guide columns and the guide plate influences forming.

Description

technical field [0001] The invention relates to a hydraulic press, specifically a high-precision hydraulic press, belonging to the field of hydraulic forming equipment. Background technique [0002] A hydraulic press is a machine that uses liquid as a working medium and is made according to Pascal's principle to transfer energy to realize various processes. During the stamping process of the existing hydraulic press for a long time, the guide plate and the guide column will be worn to varying degrees, causing the guide plate to shake during operation, resulting in the deviation of the upper die’s downward path, and ultimately affecting the forming accuracy of the workpiece. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a hydraulic press capable of slowing down the wear between the guide plate and the guide column and improving the forming precision. [0004] In order t...
