clutch screw press

Abstract

The invention provides a clutch screw press. The clutch screw press comprises a machine frame, a flywheel, a screw, a nut and a sliding block, wherein the flywheel is rotationally arranged on the machine frame, the screw is matched with the nut spirally, the nut is located in the sliding block, and the flywheel is connected with the screw through a clutch. The machine frame is further provided with a returning driving device comprising a returning motor, wherein the returning motor is provided with a pinion, the upper end of the screw is provided with a transmission shaft which is provided with a brake wheel, a rotating head and a control valve, and the brake wheel is meshed with the pinion through a returning gear. According to the clutch screw press, the sliding block is driven by the returning motor to return, and therefore a returning hydraulic cylinder is not needed; installed capacity of a driving motor can be effectively reduced, so that the clutch screw press is simpler in structure, and therefore equipment cost can be effectively reduced.

Description

technical field [0001] The invention relates to a screw press, in particular to a clutch screw press. Background technique [0002] The screw press is a press that relies on the rotation of the main screw to drive the slider to move up and down, realize the return stroke upward, and forge downward. The screw press generally uses a screw and a nut as the transmission mechanism, and the forward and reverse rotary motion of the flywheel is converted into the up and down reciprocating motion of the slider by the screw drive. When working, the flywheel is accelerated by the motor to store energy, and at the same time, the screw and nut are used to push the slider to move downward. When the slider touches the workpiece, the flywheel is forced to slow down, and the stored rotational kinetic energy is converted into impact energy. Hit the workpiece to deform it. The screw press has the characteristics of simple structure, low manufacturing cost and good working conditions, and is ...

AI Technical Summary

Problems solved by technology

But at present, the return system of this kind of clutch screw press adopts return hydraulic cylinders installed on the front, rear or left and right sides of the frame to pull the slider back, so that it is necessary to equip the return hydraulic cylinder with a complicated hydraulic system, and the equipment cost higher

Moreover, since the hydraulic cylinder pulls the slider back up vertically, it is necessary to increase the helix angle of the screw helix pair, which will reduce the transmission efficiency of the bottom equipment.
