Abstract

The invention provides a screw press which comprises an upper cross beam, a lower cross beam, nuts, a brake, a screw rod, a slide block, a driving mechanism, a motor and upright posts vertically connected between the upper cross beam and the lower cross beam; the nuts are fixed on the upper cross beam and are in threaded connection with the screw rod; the slide block is arranged at the bottom of the screw rod; and the motor is connected with the screw rod through the driving mechanism. The screw press is characterized in that a support mechanism is additionally arranged on the upper cross beam; the driving mechanism comprises a small belt pulley, a large belt pulley, a belt, and an inner sleeve and an outer sleeve which are in spline connection; external convex straight teeth are respectively and uniformly arranged on the outer wall of the inner sleeve and the inner wall of the outer sleeve, wherein the shape and the quantity of the external convex straight teeth on the outer wall of the inner sleeve and the shape and the quantity of the external convex straight teeth on the inner wall of the outer sleeve are completely the same; the inner sleeve is sleeved at the upper end of the screw rod through a key; the motor is arranged on the upper cross beam; the output end of the motor is fixedly connected with the small belt pulley; the large belt pulley is connected with the outer sleeve through a key; and the lower end of the outer sleeve is arranged on the support mechanism through a bearing. The inner sleeve and the outer sleeve are linearly contacted through the outer convex straight teeth, thus the screw press has small friction force, long service life and excellent work performance.

Description

technical field [0001] The invention provides a screw press, which belongs to the technical field of mechanical industrial equipment. Background technique [0002] Most of the existing screw presses are friction presses. The main problem is that relying on manpower or pneumatically moving the horizontal axis to control the friction plate to transmit power, the friction loss is large, the energy consumption is large, the striking force is not controlled accurately, and the qualified rate of the parts is low. High labor intensity and large amount of maintenance. The friction press is transformed into a motor-driven screw press, which has the advantages of energy saving, numerical control, and high product quality. The patent No. is 200620081609.7 for the CNC slider device, which shows that the movement of the slider can be controlled by the motor through the spline transmission, but the existing spline has a large contact area and a large friction force, resulting in high ene...
