A device for realizing high-pressure torsion process on a hydraulic press

Abstract

The invention discloses a device for realizing a high-pressure torsion process on a hydraulic press, which is characterized in that a turntable is provided, which is horizontally supported on the base of the turntable through a centripetal bearing at the waist; The transmission ring gear is provided with hydraulic motor suspension devices on the base of the turntable and on the left and right sides of the turntable respectively. The first hydraulic motor and the second hydraulic motor are independently fixed on the hydraulic motor suspension devices on the corresponding side, so that the first The hydraulic motor and the second hydraulic motor are located on the left and right sides of the turntable; the driving torque of the first hydraulic motor and the second hydraulic motor is transmitted to the turntable through the transmission ring gear; a motor, and a second motor configured with the second hydraulic motor. The invention makes it possible to realize the high-pressure torsion process on the ordinary hydraulic press, which can not only provide sufficient torque, but also achieve the purpose of precise forming by adjusting the speed.

Description

technical field [0001] The invention relates to a device for realizing plastic forming, and more specifically relates to a device for realizing a high-pressure torsion process on a hydraulic press, through which an ultra-fine-grained material is prepared. Background technique [0002] In view of the shortcomings of traditional materials, it is more and more important to study the transformation of traditional materials and the development and application of innovative materials from the relationship between internal organization, structure and material properties of materials. Improving the performance of materials mostly focuses on the refinement of grains, and the physical and mechanical properties of alloy materials are often significantly improved after obtaining ultra-fine structures. [0003] Large plastic deformation technology, referred to as SPD, has a remarkable ability to refine grains, and can refine the grain structure of materials to submicron or even nanometer...

AI Technical Summary

Problems solved by technology

[0010] For the high-pressure torsion process, because the hydraulic press in the prior art cannot realize the torsion by itself, it needs to cooperate with the electric motor to realize the high-pressure torsion process

However, due to the small torque of ordinary electric motors, the forming of larger parts cannot be realized, and at the same time, precision forming cannot be achieved due to the uncontrollable speed
