An environmentally friendly high-precision aluminum alloy profile extrusion machine

Abstract

The invention discloses an environment-friendly high-precision aluminum alloy profile extruder which comprises a base frame, a hydraulic cylinder, a material liner and a die. An abutting block is welded to the side, corresponding to a slide way, of the top end of the base frame. A cooling mechanism is arranged on one side of the abutting block. A cooling water box is welded to the top of the surface of one side of the abutting block. A second air inlet pipe staggered with a first air inlet pipe is arranged on the surface of the outer side of the cooling water box. An air inlet cover is weldedto the top end of a carrying box. A plurality of exhaust pips are inserted in the bottom end of the carrying box in a penetrating mode. A supporting plate is installed at the position, corresponding to the exhaust pipes, of the top in the carrying box. A draught fan is installed in the middle of the supporting plate. The input end of the draught fan is electrically connected with the output end ofan external power supply. Waste and scraps are carried by a drawer and a filter screen to be recycled, polluting substances generated at a high temperature are absorbed through a filtering mechanism,the harm of the waste, scraps and polluting substances to the environment is effectively avoided, and the environmental protection aim is realized.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, in particular to an environment-friendly high-precision aluminum alloy extrusion machine. Background technique [0002] The extrusion machine is the main equipment for the production of light alloy (aluminum alloy, copper alloy and magnesium alloy) tubes, rods and profiles. Through the hydraulic cylinder of hydraulic power, the hydraulic rod of the hydraulic cylinder pushes the aluminum billet into the material tank , and then the billet passes through the mold to form a long-shaped profile, and finally protrudes from the round hole of the block, enters the transmission roller for transmission, and when the billet is squeezed out, the remaining billet at the end of the mold Cutting by cutting cylinder and cutting piece; [0003] However, the existing extruder only cools the extruded aluminum profile from top to bottom by means of air injection, but the cooling effect of this me...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an environment-friendly high-precision aluminum alloy profile extruder, which can effectively solve the problem that the existing extruder only uses air injection from top to bottom to cool the extruded aluminum profile. , but the cooling effect of this method is poor, and it is easily disturbed by external dirt and dust, resulting in more potholes on the surface of the aluminum profile, making the aluminum profile easy to break, and it is not convenient to maintain the good shape and strength of the aluminum profile.
