Device and method for continuous equal channel angular extrusion of metal and alloy materials

Abstract

The invention provides a continuous equal channel angular extrusion device and method for metal and alloy materials, the device comprises a supporting rack, a main extrusion wheel mechanism, a driven rolling wheel mechanism and a deformation combined die, an extrusion wheel of the main extrusion wheel mechanism is connected to the supporting rack through a first shaft and a bearing, and an annular containing groove is formed in the peripheral surface of the extrusion wheel; an adjusting support of the driven calendering wheel mechanism is fixedly connected to the supporting rack, a calendering wheel is installed on the adjusting support through a second shaft and a bearing, a protrusion is arranged on the peripheral surface of the calendering wheel, the calendering wheel can do tangent rotation with the extrusion wheel under adjustment of the supporting rack, and the protrusion is located in the annular containing groove during tangent rotation; a die base of the deformation combined die is connected to the supporting rack, one end of the shearing die is matched with the annular containing groove and can abut against the bottom wall of the annular containing groove, and the surface, facing the extrusion wheel, of the limiting die is flush with the outer edge of the annular containing groove. The device disclosed by the invention can be used for continuously processing short samples.

Description

technical field [0001] The invention belongs to the technical field of metal and alloy material processing, and in particular relates to a device and method for continuous equal-diameter angular extrusion of metal and alloy materials. Background technique [0002] With the rapid development of aerospace, military industry, high-speed railway, power transmission, automobile and high-end equipment and other fields, the requirements for high-strength, high-conductivity metals and alloy materials continue to increase, and the lack of such materials has seriously restricted the construction of major projects in my country. At present, the preparation of high-strength and high-conductivity copper alloy materials is based on the following two aspects. One is to improve the strength of metals and alloy materials through alloying. This type of method has a good effect on improving the strength of metals, but alloying brings about a decrease in electrical conductivity. , adding 0.3% S...
