Method and device for automatically adjusting laying tension of steel wire

Abstract

The invention discloses a device for automatically adjusting the laying tension of a steel wire. The device comprises a constant-tension adjusting device and a pneumatic part, wherein the constant-tension adjusting device comprises a bracket, a spring, a tension detecting device, a linear guide rod, a linear bearing, a tension adjuster, a locating wear-resistant sleeve and a pull rod; the linear guide rod is connected and fixed to the bracket by using a nut, the spring is placed at the lower end of the linear guide rod, the tension adjuster is capable of sliding up and down on the linear guide rod through the linear bearing, the locating wear-resistant sleeve is arranged on the tension adjuster, the tension detecting device is fixed on the bracket by using a locking nut, the upper end of the linear guide rod is connected by using the pull rod, and the pneumatic part comprises a gas source treatment duplex member, an electromagnetic directional valve, a pressure regulating valve and a pneumatic tension device which are serially connected with one another in sequence. The device is capable of realizing automatic adjustment of the tension of the steel wire, and overcoming the phenomena of loosening, throwing, disordering of the steel wire due to non-uniform tension in a laying process of the steel wire, thereby meeting the production requirement and improving the product quality.

Description

Technical field [0001] The invention relates to a method and a device for automatically adjusting the tension of steel wire pay-off, and belongs to the technical field of metal product processing equipment. Background technique [0002] At present, the pay-off tension devices used in domestic steel wire drawing production include: belt type and point disc brake adjustment type, both of which are fixed tension devices and cannot realize automatic tension adjustment. During the production process, due to the changes in wheel weight and speed, the uneven wire arrangement and other factors, the required tension will also change. The fixed tension will cause the steel wire to slack, throw and chaotic, which will affect the normal production and products. Quality, and there are certain safety risks. In order to improve product quality and output, automatic adjustment of steel wire tension is realized. The device of the present invention can fully meet the requirements of production a...
