Guide rail structure for high-speed compound material hydrostatic press

Abstract

The invention relates to a guide rail device for a high-speed compound material hydrostatic press. An adjustable wedge, a fixed guide rail and a positioning plate are arranged between a hydrostatic press strut and a sliding block, wherein the adjustable wedge is fixedly connected to the sliding block through a first fixing bolt; the fixed guide rail is fixedly connected to a side wall of the strut through a second fixing bolt; a 90-degree included angle is formed between the side wall of the strut and the sliding block; the positioning plate corresponds to the adjustable wedge and is fixedly connected to the sliding block; an adjusting bolt used for adjusting a contact position between the adjustable wedge and the fixed guide rail is arranged on the positioning plate; a guiding plate is arranged between the adjustable wedge and the fixed guide rail; one side of the guiding plate is fixedly connected to the adjustable wedge; and the other side of the guiding plate is moveably attached to the fixed guide rail and is used for guiding the sliding block to move up and down along the fixed guide rail when the sliding block moves up and down. The guide rail device has the advantages that a downstream speed reaches 800mm / s and a precision demand of the hydrostatic press is met. A guide rail structure is arranged between the hydrostatic press strut and the sliding block, thereby ensuring the verticality of the sliding block during a process of pressing a workpiece and preventing the sliding block from unbalance loading.

Description

technical field [0001] The invention relates to a composite material product hydraulic press, in particular to a guide rail structure of a high-speed composite material hydraulic press which needs to ensure the precision of the hydraulic press and has a high pressing speed. Background technique [0002] With the continuous development of technology in sheet metal forming industries such as automobiles, subways, and light rails, tempered glass fiber molding products rely on their own advantages such as high strength, high toughness, controllable characteristics, anti-collision of attached paint, low weight, and low cost. An ideal substitute for products. Due to the large and irregular stress in the molding process of tempered glass fiber, the molds of FRP products are becoming more and more precise, which not only requires high positional accuracy, but also has higher requirements for horizontal accuracy in the process of sliding block pressing .

AI Technical Summary

Problems solved by technology

[0003] Currently known hydraulic presses for composite material products are limited by their own structure, and the downward speed of the slider is 300mm / s. Therefore, it is not suitable for pressing large-scale FRP products such as sheet metal products such as automobiles, subways, and light rails. This is because these FRP products are pressed. The product will cause uneven force on the four sides of the movable beam, and the situation of partial load during the pressing process is serious, and the partial load of the pressed workpiece will make the movable beam prone to excessive tilt deviation, and the frame of the hydraulic machine body is stressed unevenly. The occurrence of such a situation will cause the pressed workpiece to be pressed due to poor quality, and it will damage the mold and strain the guide rail of the fuselage, which will affect the service life of the hydraulic press.
