Example Embodiment

[0020] Example 1

[0021] A device for reducing and preventing hydrostatic extrusion billet blasting damage, figure 1 It is a schematic diagram of the extrusion cap, and an extrusion cap 9 is placed in the extrusion cylinder 3. The extrusion cap 9 is made of metal materials such as carbon steel, alloy steel, copper alloy or aluminum alloy, and the inner diameter of the extrusion cap 9 is equal to that of the billet 6 The outer diameter of the extrusion cap 9 is not greater than the inner diameter of the extrusion cylinder 3, the extrusion cap 9 is tightly fitted with the blank 6, and the front section of the extrusion cap 9 has a sealing ring 7, and the sealing ring 7 is made of copper, aluminum, Made of soft metal such as lead or magnesium, rubber or plastic, the extruded cap 9 has a liquid channel 8 with a circular or polygonal cross-section. The liquid channel 8 is located outside the outer diameter of the sealing ring 7. The total liquid channel 8 The cross-sectional area...

Abstract

The invention discloses a device for reducing and preventing hydrostatic extrusion breakdown blast-firing damages, which belongs to the technical field of extrusion processing, an extrusion cap is placed in an extrusion cylinder, the extrusion cap and a blank are in tight fit and assembly, a seal ring is arranged at the front section of the extrusion cap, a liquid channel is arranged on the outer circle of the extrusion cap, a damping hole is arranged at the bottom of the extrusion cap, extrusion liquid is filled between an extrusion rod and a mold, and the blank is extruded for obtaining a finished product. The extrusion cap moves along with the blank during the extrusion process, and the extrusion liquid can fill the whole extrusion cylinder through the liquid channel; when the extrusion is close to the end, the seal ring at the front section of the extrusion cap is in contact with the upper end surface of the mold for playing the sealing role, and then the extrusion liquid can only impose the pressure to the blank through the damping hole of the extrusion cap, thereby achieving the purpose of reducing the speed of the blank. The adoption of the device can effectively reduce and prevent the hydrostatic extrusion breakdown blast-firing damages.

Description

technical field [0001] The invention belongs to the technical field of extrusion processing, and in particular relates to a device for reducing and preventing hydrostatic extrusion billet blasting damage. Background technique [0002] Hydrostatic extrusion is a method of extrusion processing using liquid pressure. After the pressure of the extrusion liquid in the extrusion barrel increases (the extrusion rod is pushed forward or directly generated by the pump), the billet is pushed and together with the billet Extrude from the mold. Since the extrusion liquid has a good lubricating effect between the mold and the blank, the deformation of the blank is uniform during the extrusion process, and the plasticity is improved. Its advantages are that the friction force is small, the material is in a state of three-dimensional compressive stress, the deformation is uniform, and the surface quality is good. For the deformation processing of some difficult-to-deform materials with p...
