Double rotating shaft flexible skew rolling mill

Abstract

The invention relates to the technical field of metal plastic forming technologies and equipment and provides a double rotating shaft flexible skew rolling mill. The double rotating shaft flexible skew rolling mill comprises a base unit, a guide unit, two rolls, two servo main shaft systems, a roll spacing adjustment mechanism, two inclination angle adjustment mechanisms, a cooling system and a numerical control system. The two servo main shaft systems are supported and mounted by two racks and drive the two rolls to rotate; the roll spacing adjustment mechanism drives the two racks and allow the two rolls to perform synchronous centering radial press-down movement; the two inclination angle adjustment mechanisms drive the servo main shaft systems to rotate around a horizontal rolling center line and allow the two rolls to perform inclination angle adjustment movement; and the numerical control system controls rotating speeds, radial press-down and inclination angle adjustment of the two rolls, so that the skew rolling mill and the rolls in a same dimension can flexibly perform skew rolling to form shaft spare parts in different dimensions. The double rotating shaft flexible skew rolling mill has the advantages of synchronous centering press-down, high rack strength, simple mounting and debugging, flexible production and the like and has broad application prospects in the field of forming of middle and small amounts of large-diameter shaft spare 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 flexible skew rolling mill. Background technique [0002] Large-scale shaft parts are one of the key components of major equipment, and are used for power transmission and motion realization of large-scale equipment. Generally, it is subjected to composite loads such as bending, torsion, impact, and vibration under high-speed and heavy-load conditions. Its production cost, forming accuracy, and performance quality will directly affect the industries such as aerospace, rail transit, heavy machinery, and military equipment. The performance of key equipment is the prerequisite for the development of large-scale advanced equipment manufacturing industry. [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...

Problems solved by technology

The team's patent application "A device and method for two-roller flexible cross-rolling of shaft parts" (application number 201910362201.9) proposed the forming process and principle device of flexible cross-rolling shaft parts, but did not invent specific engineering equipment

[0005] At present, the skew rolling mills with similar structures mainly include frame type, machine tool type and clamp type, but all of them have the following problems: first, the equipment cannot be flexibly formed, and can only produce products of a single specification; second, the automation of the equipment is low, and the mill debugging is complicated; Third, the overall size of the equipment is large and the manufacturing cost is high
