Abstract

The invention provides a horizontal rotary-mold extrusion forming device for improving performance of products, relates to the horizontal rotary-mold extrusion forming device for improving performanceof extruded sections, and belongs to the technical field of metal plastic-forming techniques. The horizontal rotary-mold extrusion forming device comprises a horizontal extruding machine and a rotarymold device, wherein the rotary mold device is arranged on a front cross beam and composed of a servo motor, a transmission mechanism, a rotary mold sleeve, a mold, a mold seat, a first thrust bearing, a second thrust bearing, a third thrust bearing and a locking end cover. The horizontal extruding machine, a movable platform, an extruding barrel support, the front cross beam and four extension columns are horizontally mounted on the upper surface of a machine frame. The movable platform, the extruding barrel support and the front cross beam are sequentially arranged side by side in the length direction of the machine frame, and the extruding barrel support is located between the movable platform and the front cross beam. The rotary mold device is adopted in the extruding process, throughthe rotation effect of the mold, severe shear deformation is generated in a deformation area when a product is formed by extrusion, high plastic deformation can be obtained, and thus grains are refined.

Description

technical field [0001] The invention relates to a horizontal rotary die extrusion forming device for improving the performance of extruded profiles, and belongs to the technical field of metal plastic forming technology. Background technique [0002] Extrusion is a relatively common forming method in plastic forming, and it is the main forming process for preparing rods and pipes in the field of metal plastic processing. For some lightweight materials such as aluminum alloys and magnesium alloys, their original mechanical properties are not ideal, and their mechanical properties can be improved after certain plastic forming. Extrusion process is a main plastic forming method to improve its mechanical properties while obtaining extruded products such as metal rods and pipes. With the lightweight development requirements of aviation, aerospace and weaponry, higher requirements are placed on the performance indicators of lightweight materials such as aluminum alloys and magnes...
