Abstract

The invention provides a high-performance component twisting-extruding forming device, and belongs to the technical field of metal plastic machining. The high-performance component twisting-extrudingforming device comprises an extruding forming part, a twisting shearing part, a control part and a detection part. The extruding forming part applies a load through an extruding shaft to enable a blank to conduct metal flow in an extruding barrel and an extruding die to be formed; the twisting shearing part transmits torque to a twisting head through jointing of a servo motor, a worm gear reducer,a torque sensor, a coupler and a shaft, and the deformed blank achieves grain refinement under the high-pressure twisting effect of the twisting head; the control part achieves matching of twisting and extruding; and the detection part obtains extruding force of the extruding shaft, the torque of a twisting shaft, the extruding stoke and the twisting angle, and transmits obtained signals to a computer. A component is subjected to the combined effect of a pressure machine load and twisting shearing deformation in the forming process, and single-pass near-net forming of the high-performance component is finally achieved.
