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 forge rolling machine directly driven by frameless permanent magnet synchronous motors. An upper rolling wheel drive shaft and a lower rolling wheel drive shaft are connectedwith the first frameless permanent magnet synchronous motor, and the first frameless permanent magnet synchronous motor is fixedly installed on an upper rolling wheel support and a lower rolling wheel support through motor brackets; a screw rod shaft of a screw rod is connected with the second frameless permanent magnet synchronous motor, the other end of the screw rod is connected to the upper rolling wheel support through a nut, and the second frameless permanent magnet synchronous motor is fixed to a machine frame through a motor bracket. The frameless permanent magnet synchronous motors are adopted as rolling wheel drive motors, so that drive intermediate links like a transmission part are reduced, the drive mode and structure are simplified, the drive efficiency is improved, direct driving of rolling wheels is achieved, the running reliability of the machine can be improved, the manufacturing cost and the usage cost are reduced, and the energy loss is reduced.

Description

technical field [0001] The invention relates to the field of forging machinery and equipment, in particular to a roll forging machine directly driven by a frameless permanent magnet synchronous motor. 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 techni...
