A split-flow die for aluminum alloy extrusion molding and its working method

Abstract

The invention relates to the field of mechanical processing, in particular to a flow-distributing die for aluminum alloy extrusion molding and its working method, comprising a base and a lifting mechanism, the lifting mechanism includes a vertical plate and a lifting assembly, and a cantilever is slidably arranged on the lifting mechanism. The bottom of the cantilever is fixedly equipped with an upper mold, and also includes a controller, a processing table and a pushing mechanism. The top of the base is fixedly provided with a support plate. There is a lower mold, and the pushing mechanism is set at the bottom of the processing table to realize the diversion of the mold. The pushing mechanism includes a driving assembly, a rotating assembly and four top wheel assemblies, and the lifting assembly and the driving assembly are electrically connected to the controller , a split-flow die for aluminum alloy extrusion molding and its working method of the present invention can ensure that the aluminum alloy material is evenly pressed, and at the same time can ensure that the top wheel can fully squeeze the workbench, which is beneficial to the rapid prototyping of the aluminum alloy material and improves the processing efficiency .

Description

A shunt die for aluminum alloy extrusion and its working method technical field The present invention relates to the field of machining, be specifically related to a kind of aluminum alloy extrusion molding with split flow die and work thereof method. Background technique Extrusion is a common industrial processing technology, commonly used in processing radiator profiles, aluminum / titanium pipes, construction Aluminum profiles, tools special-shaped aluminum and other products. In the production of extrusion dies, pipes are divided into seamed pipes and seamless pipes. Produced with a flat split extrusion die, the seamed pipe has poor pressure bearing and pressure resistance due to the existence of welds. existing aluminum Alloy split extrusion dies are mostly matched by an upper die and a lower die, and are formed by forced extrusion through external force. However, the extrusion does not have a guiding function, and the extrusion force area is relatively scatte...

AI Technical Summary

Problems solved by technology

[0006] 1. Use a single top wheel to extrude the aluminum alloy material in the mold. The top wheel can only extrude in one direction, so it is impossible to ensure that the aluminum alloy material in the mold is evenly compressed. Therefore, the diversion effect of the mold needs to be determined promote

[0007] 2. Although the telescopic rod and the sleeve are in clearance fit, there is no specific internal structure designed. After the horizontal plate is subjected to the pressure exerted by the upper die, it cannot guarantee the supporting effect of the top wheel, so that the support of the top wheel to the workbench cannot be guaranteed. The extrusion effect cannot guarantee the extrusion molding of the aluminum alloy material inside the lower die. Therefore, the practicability of the die needs to be improved
