High-energy clutch screw press

Abstract

The invention discloses a clutch screw press which comprises a frame, a driving mechanism and a sliding block and a fly wheel which are arranged in the frame. The driving mechanism is connected with the excircle of the fly wheel and drives the fly wheel to rotate. A vertical moving disc is arranged in the frame and is connected with the sliding block through a screw pair. A toggle rod type clutch mechanism and a return disc are further arranged on the vertical moving disc, the toggle rod type clutch mechanism is connected with in the inner circle of the fly wheel through a friction block, the excircle of the return disc is connected with a brake and a return mechanism respectively, a return clutch is arranged in the return mechanism, and the return mechanism is connected with the driving mechanism through the return clutch. When the clutch screw press works, forging pressing and returning of the press can be achieved by driving a motor to rotate in the positive direction continuously.

Description

technical field [0001] The invention relates to a screw press, in particular to a high-energy clutch screw press. Background technique [0002] The screw press is a forging machine that uses a screw and a nut as a transmission mechanism, and converts the positive and negative rotary motion of the flywheel into the up and down reciprocating motion of the slider by the screw drive. Existing screw presses have the following forms: double-disc friction screw presses, electric screw presses and clutch screw presses. [0003] Due to the large friction and slippage of the double-disc friction press when the friction disc is combined with the flywheel, the mechanical kinetic energy loss is relatively large. Since the motor directly drives the flywheel to rotate in the electric screw press, the flywheel must be accelerated from zero to the rated speed twice in each working cycle, so the motor needs to be started in forward and reverse directions frequently. For example, the Chinese...

AI Technical Summary

Problems solved by technology

During the forging process of the electric screw press, the first motor needs to rotate forward and reverse frequently, so the electric screw press has defects such as large installed capacity and large impact on the power grid.

As the clutch screw press currently adopts a dry clutch structure, the friction plate is severely worn, the replacement cycle is short, and the flywheel always rotates in the same direction, so the return of the slider needs to be provided with a return mechanism. A complex hydraulic return system increases energy consumption and is difficult to maintain and costly to use
