Device for realizing high-pressure twisting process on hydraulic press

Abstract

The invention discloses a device for realizing a high-pressure twisting process on a hydraulic press. The device is characterized by comprising a revolving table, wherein the revolving table is horizontally supported on a turntable base through a waist centering bearing; a transmission gear ring is arranged on the top peripheral surface of the revolving table; hydraulic motor hanging devices are arranged at the left and right sides of the revolving table on the turntable base respectively; a first hydraulic motor and a second hydraulic motor are independently fixed on the hydraulic motor hanging devices at the corresponding sides respectively, so that the first hydraulic motor and the second hydraulic motor are positioned at the left and right sides of the revolving table respectively; driving torques of the first hydraulic motor and the second hydraulic motor are transferred to the revolving table through the transmission gear ring; and a first motor matched with the first hydraulic motor and a second motor matched with the second hydraulic motor are arranged respectively. The device can realize the high-pressure twisting process on a general hydraulic press, can provide sufficient torques, and can achieve the precise forming purpose through speed adjustment.

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...

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
