Description

Technical Field

[0001] The invention relates to the technical field of static presses, in particular to a cold isostatic press. Background Art

[0002] A cold isostatic press is a machine that places materials loaded into a sealed, elastic mold in a container filled with liquid or gas, applies a certain pressure to the materials with the liquid or gas, and presses the materials into a solid body to obtain a blank of the original shape. When running on the isostatic press, the product needs to be limited by a fixed frame, which is convenient for loading and unloading and lifting, and also convenient for limiting the position of the product, so that the product is stable during processing. Most of the existing technologies use two parallel fixed plates and set multiple vertical bars at the edges of the fixed plates for blocking. The positioning effect is relatively general, and the existing structure of lifting by hooks has poor stability for product lifting. The product may shake during lifting and placement, thereby affecting the lifting stability and efficiency of lifting and placement.

[0003] For example, a vertical cold isostatic press with announcement number CN214563198U includes a bottom plate, a support plate welded on the top of the bottom plate, a top plate fixedly installed on the top of the support plate, a roller plate attached to the front surface of the bottom plate, a mounting plate fixedly installed on the top of the roller plate, an electric telescopic rod fixedly installed on the top of the mounting plate, a roller shell fixedly installed on the top of the electric telescopic rod, a first bearing fixedly installed on both sides of the inner wall of the roller shell, and a connecting plate threadedly connected to the top of the top plate by fixing bolts. The roller plate can be attached to the front surface of the bottom plate first, and then the high pressure The container is placed on the top of the roller, and then the high-pressure container is pushed so that the high-pressure container slides on the top of the roller. The outer surface of the roller fits the outer surface of the high-pressure container. When the high-pressure container is pushed forward, the first bearing of the rotating rod inside the roller rotates internally. However, the existing structure for lifting by hooks has poor stability for product lifting. The product may shake during lifting and placement, thereby affecting the lifting stability and efficiency of lifting and placement. The device uses two parallel fixed plates and sets multiple vertical bars at the edges of the fixed plates for blocking. The positioning effect of the product is relatively general.

[0004] Therefore a cold isostatic press is proposed to solve the above-mentioned problems. Summary of the Invention
