A preformed aluminum alloy extrusion molding device and molding process

Abstract

The invention discloses a preformed aluminum alloy extrusion molding device. One end of the top of the installation base is fixedly connected with an extruder main body, and both ends of one side of the extruder main body are fixedly connected with installation slide rails. The top of the installation base is fixedly connected with the drive installation seat at the position corresponding to one end of the installation slide rail, and the middle part of one side of the extrusion slide seat is fixedly connected with an extrusion column, and one end of the extrusion column is provided with an anti-stick extrusion mechanism. Through the cooperation of the driving column and the driving spiral groove, the invention twists the connection between the extrusion head and the extruded aluminum alloy, which effectively reduces the adhesive strength between the extrusion head and the aluminum alloy, thus ensuring that the extrusion head When withdrawing from the extrusion die, a large amount of aluminum alloy will not be brought out, avoiding the need to replace the extrusion head after each extrusion, reducing the processing procedures of aluminum alloy extrusion and shortening the extrusion process of aluminum alloy. The processing interval of press forming improves the processing efficiency.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing equipment, in particular to a preformed aluminum alloy extrusion molding device and a molding process. Background technique [0002] Aluminum alloy profiles are the most widely used non-ferrous metal structural materials in the industry. They have been widely used in aviation, aerospace, automobiles, machinery manufacturing, ships, construction, decoration and chemical industries. With the development of science and technology and industrial economy in recent years With the rapid development, the demand for aluminum alloy welded structural parts is increasing day by day, so that the research on the weldability of aluminum alloy is also in-depth. The existing aluminum alloy profiles are mainly formed by extrusion. Used in aluminum alloy extrusion machine; [0003] However, due to the lack of corresponding anti-sticking mechanism in the aluminum alloy extrusion molding devices cur...

Problems solved by technology

[0003] However, due to the lack of corresponding anti-sticking mechanism in the aluminum alloy extrusion molding devices currently on the market, when the extrusion head is extruding the aluminum alloy, it will stick to the aluminum alloy under the action of high temperature and high pressure. When withdrawing from the extrusion mold, it is easy to bring out a large amount of residual aluminum alloy in the mold. In order to ensure the normal use of the extrusion molding device, the extrusion head needs to be replaced every time the extrusion is completed, thus increasing the aluminum alloy extrusion molding process. , reducing the processing efficiency
