Upward pull type paying-off stress eliminating device

Abstract

The invention discloses an upward pull type paying-off stress eliminating device. The device comprises a steel wire coil, a first guide wheel, a second guide wheel, an eccentric wheel and a water tank car, wherein the steel wire coil coats a longitudinal bracket; a steel wire passes through the first guide wheel, the second guide wheel and the eccentric wheel in sequence to finally reach the water tank car; a counterweight wheel is arranged below the second guide wheel; and a disordered wire limiting switch is arranged on the counterweight wheel. A straightening wheel combination is arranged between the steel wire coil and the first guide wheel. The device can largely reduce the upward pull stress of steel wires; and in the straightening process, the steel wires can forwards push a stream of yielding force in straightening, so that the steel wires are farther from a wire stand, the friction force of the steel wires and the wire stand is correspondingly reduced, and the service life of the wire stand is prolonged. The device enables the upward pull tension of the steel wires to naturally become less, and the counterweight wheel cannot be pulled up, so that the normal operation of equipment is guaranteed, the workload of manual maintenance and adjustment is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of steel wire rope processing, and more specifically, relates to a pull-up type pay-off stress relief device. Background technique [0002] There are many ways to pay off the water tank wire drawing machine. According to the form of the pay-off rack, it can be divided into: I-shaped wheel passive rotary pay-off, flower basket rack passive rotary pay-off and wire rack pull-up pay-off. At present, our company is using the drawing-out type pay-off on the wire frame. Since the steel wire itself has a fixed ring diameter, it forms stress under the action of gravity. During the upward drawing process, the ring diameter will become smaller and smaller. When the steel wire is close to the wire frame, the friction force will also increase, and finally the tension of the pay-off steel wire will be too large. [0003] How to reduce the friction of the steel wire on the wire frame, reduce the loss of the wire frame, el...
