Abstract

The invention relates to the field of machining, in particular to a flow dividing type die for aluminum alloy extrusion forming and a working method thereof. The flow dividing type die comprises a base and a lifting mechanism, the lifting mechanism comprises a vertical plate and a lifting assembly, a cantilever is arranged on the lifting mechanism in a sliding mode, an upper die is fixedly arranged at the bottom of the cantilever, the flow dividing type die further comprises a controller, a machining table and a pushing mechanism, a supporting plate is fixedly arranged at the top of the base,four telescopic rods are symmetrically arranged at the top of the supporting plate, a lower die is fixedly arranged at the top of the machining table, the pushing mechanism is arranged at the bottom of the machining table to achieve flow dividing of the die and comprises a driving assembly, a rotating assembly and four top wheel assemblies, and the lifting assembly and the driving assembly are electrically connected with the controller. According to the flow dividing type die for aluminum alloy extrusion forming and the working method thereof, it can be guaranteed that aluminum alloy materialsare evenly pressed, meanwhile, it can be guaranteed that the top wheel sufficiently extrudes a workbench, rapid forming of the aluminum alloy materials is facilitated, and the machining efficiency isimproved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a flow-distributing mold for aluminum alloy extrusion molding and a working method thereof. Background technique [0002] Extrusion molding is a commonly used industrial processing technology, which is often used in the processing of radiator profiles, aluminum / titanium pipes, architectural aluminum profiles, and special-shaped aluminum profiles for tools. In the production of extrusion dies, pipes are divided into seamed pipes and seamless pipes. Seamed pipes are produced by plane split extrusion dies. Seamed pipes have poor pressure bearing and pressure resistance due to the presence of welds. Most of the existing aluminum alloy shunt extrusion dies cooperate with an upper die and a lower die to form products through forced extrusion by external force, but they do not have a guiding function during extrusion, and the force-bearing area of ​​extrusion is relatively scattered...

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
