Changing device of extrusion container assembly

Abstract

The invention provides a changing device of an extrusion container assembly. The changing device comprises an electric cylinder and a clamping part, wherein the electric cylinder is fixed on an extrusion container guiding support; the clamping part is connected with an output shaft of the electric cylinder and can do a rectilinear motion along with the output shaft, when the clamping part moves to be contacted with a groove of the extrusion container assembly, the changing device of the extrusion container assembly is in a clamping state, and the extrusion container assembly is clamped on an extrusion container shell; when the clamping part moves to be separated from the groove of the extrusion container assembly, the changing device of the extrusion container assembly is in a loosening state, and the extrusion container assembly is separated from the extrusion container shell. The changing device of the extrusion container assembly provided by the invention has the advantages that the electric cylinder controls the clamping part to do a rectilinear motion between the loosening state and the clamping state to realize the release or constraint of the extrusion container assembly, and thus the extrusion container assembly is changed; according to the invention, the changing efficiency is greatly improved, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to extruder equipment, in particular to an extruding cylinder component replacement device. Background technique [0002] The extrusion barrel assembly is the container for the billet during the extrusion process. It is the most expensive part of the extrusion barrel device. It is usually composed of two or more layers of bushes assembled together with interference heat fit. The working environment of the extrusion barrel assembly is very harsh, and it has been subjected to high friction, high temperature, and large alternating loads for a long time, resulting in premature failure of the extrusion barrel, such as expansion deformation and cracking of the jacket, expansion deformation, and cracking of the inner lining. The axial movement of the lining, the plastic deformation of the contact surface between the end surface of the lining and the extrusion die, etc., therefore, it is inevitable to replace the extrusion cylinder assemb...

AI Technical Summary

Problems solved by technology

During the entire replacement process, due to the inertia of the deceleration motor, it is often difficult to rotate the protrusion in the inner hole of the large ring gear to the position aligned with the slot designed on the outer casing of the extrusion cylinder, and it is difficult to replace the extrusion cylinder assembly smoothly; followed by To control the braking position of the deceleration mo
