Double rotating shaft type electric servo flexible skew-rolling mill

Abstract

The invention relates to the technical field of metal plastic forming process and equipment, and provides a double rotating shaft type electric servo flexible skew-rolling mill. The double rotating shaft type electric servo flexible skew-rolling mill includes a base unit, a machine frame synchronization unit, two rolls, two main shaft rotation systems, an axial thrust system, two roll inclinationangle adjustment systems, a roll pitch adjustment system and a counterweight unit. The base unit supports a whole machine body of the skew-rolling mill. The axial thrust system exerts axial thrust ona blank. The machine frame synchronization unit ensures that the two machine frames are pressed down synchronously in a centring mode. The two main shaft rotation systems drive the rotation of the tworolls. The inclination angle adjustment system adjusts the inclination angle between the axis line of the two rolls and the axis line of the blank, the roll pitch adjustment system adjusts the roll pitch of the two rolls, and the counterweight unit reduces the torque required by the inclination angle adjustment system. Driven by a servo motor and controlled by a servo driver, the double rotatingshaft type electric servo flexible skew-rolling mill has the advantages of compact structure, high degree of automation, low vibration noise, wide rolling range and the like, and is suitable for flexible skew rolling of large shaft parts.

Description

technical field [0001] The invention relates to the technical field of metal plastic forming technology and equipment, in particular to a double-shaft electric servo flexible skew rolling mill. Background technique [0002] Large-scale shaft parts are one of the key components of major equipment manufacturing. They are used for power transmission and motion realization of large-scale equipment. Cannon barrels, etc. Large-scale shaft parts are generally subjected to complex loads such as bending, torsion, impact, and vibration under high-speed and heavy-duty conditions. Therefore, their production costs, forming accuracy, and performance quality will directly affect rail transportation, steel rolling machinery, hydropower, and ships. The industrial base of manufacturing and other industries is the prerequisite for the development of heavy-duty advanced equipment manufacturing. [0003] At present, the forming processes of large-scale shaft parts mainly include: first, free ...

AI Technical Summary

Problems solved by technology

[0003] At present, the forming processes of large-scale shaft parts mainly include: first, free forging and rapid forging are used. This process does not need to design special molds, and the production flexibility is high, but it has low production efficiency, low product precision, low degree of automation, and stable product quality. Poor performance and other problems restrict the production of high-quality shaft parts; the second is radial forging, which has high precision and is currently the main method for forming large shaft parts. High cost and other issues; the third is cross wedge rolling forming, which can be formed with high efficiency and precision through the development of product molds, but there are problems such as large mold size, high processing cost, and inflexible production.
