Centering and cold material pushing-out method for die holder of aluminum alloy profile extruding machine

Abstract

A centering method for a die holder of an aluminum alloy profile extruding machine comprises the following steps that the die holder is provided, a containing cavity is formed in the die holder in a hollow mode, a centering piece is coaxially embedded in the containing cavity, and a centering cavity is formed in the centering piece in a hollow mode; an extrusion cylinder is provided, and an extrusion cavity is formed in the extrusion cylinder in a hollow mode; wherein the inner diameter of the centering cavity is equal to the inner diameter of the extrusion cavity, the die holder is provided with a fine adjustment part along the periphery, and during use, the position of the die holder is finely adjusted through the fine adjustment part, so that the centering cavity and the extrusion cavity are coaxially arranged, and the centering function of the extruder is further completed. According to the centering method, the mold set for cooling and centering is replaced with the centering piece, the boundary dimension of the mold set is equal to that of the centering piece, installation is convenient, time is saved, and high-precision centering operation is achieved.

Description

technical field [0001] The invention belongs to the technical field of profile processing equipment, and in particular relates to a method for centering a die base of an aluminum alloy profile extruder and pushing out a cold material. Background technique [0002] During the extrusion process of aluminum alloy profiles, there will be material blocking. In order to avoid this situation and extrude qualified aluminum alloy profiles, the extrusion die needs to be installed in place. Otherwise, when the position of the extrusion die is not installed in place, the aluminum rod will be difficult to extrude during extrusion, which will increase the difficulty of extrusion, and there will be unqualified aluminum alloy profiles, and even serious blockages will occur, that is, The aluminum rod is jammed in the extrusion barrel, which may cause damage to the equipment. Therefore, it is necessary for the operator of the extrusion machine to accurately adjust the position of the extrusi...

AI Technical Summary

Problems solved by technology

[0004] The existing method of adjusting the centering position of the extruder die base may cause various problems due to the improper installation of the extrusion die, and then readjust the position of the extrusion die, and repeat the above steps to adjust the die. seat position

That is, it delays production time, seriously affects work efficiency, and affects production and wastes production costs including raw materials. More seriously, it may cause equipment damage and cause greater losses.
