Special horizontal high-isostatic pressing device for ceramic rollers

Abstract

The invention discloses a special horizontal high-isostatic pressing device for ceramic rollers, which is used to apply uniform static high pressure to strip-shaped workpieces, namely ceramic rollers. The high-isostatic pressing device comprises a frame, a static pressure cylinder, a movable oil cylinder, a lift oil cylinder, a fixed plug head, a movable plug head and a high-pressure liquid supply system, wherein the static pressure cylinder has two ends opened, is in the shape of a round tube, is used to hold high-pressure liquid and the strip-shaped workpieces and is arranged transversely; the movable end of the movable oil cylinder is connected with the static pressure cylinder; the movable end of the movable oil cylinder is connected with the lift oil cylinder; the fixed plug head and the movable plug head are arranged on the frame and separately plug openings at two ends of the static pressure cylinder to form a sealed static pressure cavity; and the high-pressure liquid supply system is communicated with the static pressure cavity. The horizontal high-isostatic pressing device is horizontally arranged on the ground, and has the advantages of filtering and then recycling media so as to avoid blocking hydraulic pipelines, along with easy convenient installation, low cost, convenient operation of loading / unloading workpieces and good installation and using stability.

Description

technical field [0001] The invention relates to an isostatic pressing device, in particular to a high isostatic pressing device specially used for manufacturing ceramic roller rods for applying uniform static high pressure to workpieces. Background technique [0002] The traditional method of firing ceramic rollers is to directly fire the tubular rollers formed by grouting or extrusion to form finished products, and the strength of the products depends on the composition of the materials. The existing ceramic rollers are generally formed by isostatic pressing, which is formed by extruding the billet onto the metal pipe through a pipe extruder, then putting on a rubber sleeve, sealing both ends, and releasing the mold after pressurization and pressure relief. , the calcined product is not easily deformed, has uniform density, small shrinkage, and high bending strength. [0003] Because the traditional ceramic roller is relatively short, the early isostatic pressing equipment...

AI Technical Summary

Problems solved by technology

Since the frame is heavier than the static pressure cylinder, a larger force is required to move the frame, and the equipment will be unstable after the frame is removed; and since the frame occupies a large space, the space required for moving is also large, and the requirements for the factory building are relatively large. high

[0004] Vertical isostatic pressing equipment is generally installed in the basement. When loading and unloading workpieces, the ceramic rollers are transported horizontally to the side of the isostatic pressing equipment on the ground, and then erected into the static pressure cylinder. After the isostatic pressing is completed, the ceramic rollers need to be vertically The roller bar is lifted, then turned 90° to be transported to the next station horizontally (horizontally placed), the process of loading and unloading the workpiece is very inconvenient, and the basement needs to be excavated, the installation is complicated and the installation cost also needs to be increased. Maintenance is also very inconvenient

Usually, the supercharger for applying pressure to the isostatic pressure equipment is installed on the ground, and the pipes required to connect the isostatic pressure equipment in the basement are relatively long, and the increase in pressure is limited to a certain extent

[0005] The vertical isostatic pressing equipment can also be installed on the ground. When loading and unloading the workpiece, the workpiece needs to be lifted to the upper opening of the static pressure cylinder for loading and unloading of the workpiece. At a position higher than the ground, the long workpiece needs to be turned 90°. It makes the loading and unloading operation particularly inconvenient, and has great requirements on the height of the factory building

Moreover, it is inconvenient to install on the top of the equipment, and the stability of the equipment is poor.

[0006] In addition, when the vertical isostatic pressure equipment loads and unloads workpieces, generally only the upper movable plug is opened, and most of the media stored in the static pressure cylinder are not discharged, because these media, such as emulsified oil and hydraulic oil, have accumulated in the static pressure for a long time. In the cylinder, the impurities generated during the operation are mixed in the medium, which may easily cause blockage of the hydraulic pipeline

[0007] When a workpiece with a shorter length is placed in the static pressure chamber of the vertical isostatic pressure equipment for isostatic pressing, it is inconvenient to use a tool to insert or remove the workpiece from a deep place to take it out.

[0008] As ceramic rollers need to be longer and thicker, vertical isostatic pressing equipment is gradually unable to meet the production conditions of thick and long ceramic rollers
