Problems solved by technology
When the clutch + disc brake brakes, due to the high number of rotations per minute and the number of starts and stops of the main shaft, the wear of the clutch and the disc brake is very serious under this working condition, and the service life is short; relying on the friction between the workpiece and the forging hammer. moving, the workpiece will bear torque, which is not conducive to the improvement of product quality

Embodiment Construction
[0013] The present invention is realized like this, as Figure 1~4 As shown, before the forging process starts, the main motor 2 keeps rotating at a constant speed, the worm shaft 4 drives the worm gear 25 and the manipulator main shaft 26 to rotate, and balances the first oil inlet hole 10 on the cylinder block 9 with the constant pressure oil supply pipeline connected with each other; according to the motor speed, the speed of the worm shaft and the axial partial velocity v of the worm teeth can be calculated 0 ; When the second oil inlet hole 14 enters oil and the third oil inlet hole 15 is closed, the piston rod 13 pushes the worm shaft 4 to move to the left through the right connecting shaft 7; otherwise, when the third oil inlet hole 15 enters oil, the third oil inlet hole When the second oil inlet hole 14 is closed, the worm shaft 4 is pushed to move to the right, thus the axial velocity v′ of the worm shaft 4 under the action of the main hydraulic cylinder 16 can be obt...

The invention provides a radial forging manipulator for regulating speed and braking by axial movement of a worm, and belongs to the field of radial forging equipment. The radial forging manipulator for regulating speed and braking by axial movement of the worm is characterized in that nodal velocity generated by rotation of a worm shaft driven by a main motor through belt transmission and axial feed velocity generated by the worm shaft pushed by a main hydraulic cylinder are synthesized; when the magnitude and direction of the nodal velocity and the magnitude and direction of the axial feed velocity are consistent, nodal synthesized velocity is increased, and the manipulator clamps a workpiece to rotate; when the magnitude and direction of the nodal velocity and the magnitude and direction of the axial feed velocity are opposite, the nodal synthesized velocity is reduced; and when the magnitude of the nodal velocity and the magnitude of the axial feed velocity are equal to each otherand the direction of the nodal velocity and the direction of the axial feed velocity are opposite, a worm gear and a spindle of the manipulator stop rotating, and at the moment, a forging machine carries out forging. The radial forging manipulator for regulating speed and braking by axial movement of the worm has the advantages that problems of slow braking and severe abrasion due to cooperation of a clutch and a disc brake and the problem of workpiece distortion caused by braking of a force of friction between a forging hammer and the workpiece are solved, and the radial forging manipulator is stable in running, simple in structure and long in service life.
Description
technical field [0001] The invention belongs to the field of radial forging equipment, in particular to a radial forging manipulator which uses the axial feed motion of a worm for speed regulation and braking. Background technique [0002] Radial forging belongs to rapid forging forming. It has the advantages of fast forming rhythm, short downtime, high workpiece quality, not limited by material temperature and high material homogeneity. Based on the above advantages, radial forging has been used more and more . [0003] The key to the successful realization of radial forging lies in the close cooperation between the forging hammer and the manipulator, which requires the manipulator to be able to realize the functions of rotating, axially feeding and axially following the workpiece, that is, within the contact time between the forging hammer and the workpiece , the main shaft of the manipulator stops rotating, and the moment the forging hammer leaves the workpiece, the main...
