Tension mechanism of paying-off device

Abstract

The invention discloses a tension mechanism of a paying-off device. The tension mechanism comprises a guiding disc, a plurality of radial moving blocks, axial moving blocks and an axial driving mechanism, wherein the guiding disc is fixedly arranged on a main shaft of the paying-off device; the radial moving blocks are distributed in the circumferential direction of the main shaft, and a radial guiding groove and a protrusion structure matched with the corresponding radial guiding groove are arranged between each radial moving block and the guiding disc; the axial moving blocks are surrounded in the radial moving blocks, the axial moving blocks can move in the axial direction of the main shaft, the matched surfaces of the radial moving blocks and the axial moving blocks are bevels, and the axial moving blocks drive the radial moving blocks to expand outwards when the axial moving blocks are displaced forward in the axial direction; the axial moving blocks drive the radial moving blocks to retract inwards when the axial moving blocks are displaced reversely in the axial direction; and the axial driving mechanism is used for driving the axial moving blocks to move axially. In this way, according to the tension mechanism of the paying-off device, the stability of a coil can be ensured, and the problems of wire clamping and collapsing of the coil in the paying-off process can be prevented.

Description

technical field [0001] The invention relates to the technical field of cable take-up and pay-off, and more specifically, to a tensioning mechanism of a pay-off device. Background technique [0002] The domestic rolling mill adopts a loose coil-type closing rod, and a frame-mounted pay-off frame is used in the subsequent process to pay off the wire. In the prior art, aluminum rods or aluminum alloy rods are coiled into coils, and the rack-mounted pay-off method is adopted when paying off. During the pay-off process, the coils are fixed and the axial direction is vertical. During the pay-off process, the aluminum rod or aluminum alloy rod is pulled out by pulling force, and this kind of pay-off method is from the outside to the inside, which is prone to unstable phenomena such as line jamming and collapse during the pay-off process. The existing rack-mounted pay-off Racks can no longer meet the requirements of efficient production. Contents of the invention [0003] In vie...
