Clutch type electric screw press

Abstract

The invention relates to a clutch-type electric screw press which comprises a frame, a driving motor which is arranged above the frame, a clutch flywheel which is driven by the driving motor, a clutch which is arranged on the clutch flywheel, a friction disc which can drive the clutch to rotate after the clutch is jointed, an electric flywheel which is fixed with the friction disc and which is driven by the motor, a screw rod which is fixed on the electric flywheel and a slide block which is arranged at the lower part of the screw rod and which is provided with an internal thread. The clutch-type electric screw press of the invention has large capacity, wide technical adaptation range, strong reliability and safety, long service life and low total power of the motor and can be widely applied in the pressure shaping technique.

Description

[0001] Technical field The present invention relates to a clutch-type electric screw press, which can be widely used in press forming processes. Background technique [0002] Existing electric screw presses generally adopt a motor to drive the flywheel and the screw to rotate through a belt or a gear, and drive the slide block to strike through the screw pair. Due to the small transmission ratio and short stroke, this structure cannot meet the high energy demand of the screw press. Another type of screw press adopts the direct drive type, that is, the flywheel and the motor rotor are integrated, and the stator is fixed on the top surface of the upper beam. This structure reduces the transmission chain to the shortest, but there is still the problem of insufficient input energy, and the cost is expensive. Defects such as large starting current. There is also a clutch type screw press, which is driven by the main motor through the belt to make the large flywheel rotate continuo...

AI Technical Summary

Problems solved by technology

It can be seen from the transmission mode that when the screw and the nut are struck downward, the return stroke of the slider ends, and the whole process of the slider staying at the top dead center is in contact with the upper surface of the screw tooth surface, the lubrication condition is very poor, and the lubricating oil The condition of the flywheel is very high, which leads to an increase in the cost of use. Another problem is that the service life of the large flywheel is too large and the speed is high, so it is difficult to replace
