Problems solved by technology

At present, the drive of the roll forging machine is generally composed of a motor, a V-belt, a reduction box, and a transmission gear. There are many intermediate transmission parts, the power loss is large, and the transmission accuracy is low; The wedges or threads at both ends are manually adjusted, and the moving positions of the two ends are not easy to keep consistent in actual operation. These problems are not conducive to the precise processing of rolled parts

Abstract

The invention discloses a frameless combination type permanent magnet synchronous linear motor direct-driven roll-forging machine. First frameless combination type permanent magnet synchronous linearmotors are connected to an upper roll wheel drive shaft and a lower roll wheel drive shaft respectively and are fixedly installed on an upper roll wheel supporting seat and a lower roll wheel supporting seat through motor brackets respectively; second frameless combination type permanent magnet synchronous linear motors are connected to a screw rod shaft of a screw rod; the other end of the screwrod is connected to the upper roll wheel supporting seat through a nut; and the second frameless combination type permanent magnet synchronous linear motors are fixed on a rack through motor bracketsrespectively. For the frameless combination type permanent magnet synchronous linear motor direct-driven roll-forging machine, by adopting a frameless combination type permanent magnet synchronous linear motor as a roll wheel drive motor to reduce drive intermediate links of a transmission part and the like, a drive mode and the structure are simplified, the drive efficiency is improved, direct drive of a roll wheel is realized, the running reliability of a machine can be improved, the manufacturing and use costs are lowered, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of forging machinery equipment, in particular to a frameless combined permanent magnet synchronous linear motor direct-driven roll forging machine. Background technique [0002] The roll forging machine is mainly used for pre-forging of forgings, and can also be used for final forging. The essence of roll forging deformation is the rolling extension of the blank. At present, the drive of the roll forging machine is generally composed of a motor, a V-belt, a reduction box, and a transmission gear. There are many intermediate transmission parts, the power loss is large, and the transmission accuracy is low; The wedges or threads at both ends are manually adjusted, and the moving positions of the two ends are not easy to keep consistent in actual operation. These problems are not conducive to the precise processing of rolled parts. [0003] Therefore, there is an urgent need for a new driving method to solve the above t...
