Embodiment Construction

[0009] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0010] See the driving mechanism of the four-wheel friction screw press shown in the accompanying drawing, which has a horizontally rotating flywheel 1, the flywheel 1 is fixedly connected with the screw rod 16, and is connected to the bed through the plane bearing 15 (see the part indicated by the oblique line in the figure, attached All parts represented by slash lines in the figure are bed) rotation connection, flywheel 1 is left-handed or right-handed by the effect of friction wheel, and screw rod 16 drives slider to move up and down to implement forging operation, which is the difference between the present invention and the prior art. place. The difference is that an upper friction wheel 2 and a lower friction wheel 3 are arranged symmetrically on both sides of the flywheel 1 in the present invention. Because the structures on both sides are ...

Abstract

The invention relates to a driving device of a four-wheel friction screw press, comprising a flywheel rotating horizontally; wherein, the flywheel is connected with a screw; an upper friction wheel and a lower friction wheel driven by a motor are symmetrically positioned on the two sides of the flywheel; four friction wheels rotate in the same direction; the rotating shafts of the upper friction wheel and the lower friction wheel are movably connected with the two ends of a lever by a pin; the lever driven by an oil pressure cylinder swings with the pivot as the center, and controls the upper friction wheel and the lower friction wheel to press and leave the wheel margin of the flywheel alternately; the piston rods of two oil pressure cylinders move towards the middle flywheel; simultaneously, the lower friction wheel presses the inferior margin; the flywheel rotates to the right; a sliding block presses down; the piston rods of two oil pressure cylinders move outwards; simultaneously, the upper friction wheel presses the upper margin of the flywheel; the lower friction wheel leaves the flywheel; the flywheel rotates to the left; the sliding block is lifted. The driving mechanism has the advantages that the friction wheels on the two sides press the flywheel oppositely with the same force in operation, thus eliminating the lateral force borne by the screw; strong forging ability and high productivity can be obtained when the load is increased.

Description

【Technical field】 [0001] The invention relates to a friction screw press in forging machinery, in particular to a driving mechanism of a four-wheel friction screw press. 【Background technique】 [0002] The traditional friction screw press is a two-wheel drive mechanism in which a friction wheel is arranged on both sides of the flywheel, one is to press down the friction wheel, and the other is to lift the friction wheel. During the forging process, the two friction wheels alternately press and release the flywheel. With such a structure, the screw will be subject to a large lateral force during the rotational movement, especially for the trapezoidal thread transmission with a large pitch, the friction between the thread teeth will be greatly increased, which not only reduces the mechanical efficiency of the transmission, but also causes cost The expensive copper nut wears in one direction, so it not only increases the power loss, shortens the service life of the equipment, ...
