Damped pay-off device

Abstract

The invention relates to a damped pay-off device, specifically relating to a device for passive paying off of a drawing machine and belonging to the technical field of the drawing machine equipment. The damped pay-off device mainly comprises a base, a spool seat, a shock-absorbing seat, a tension spring seat, a screw, a damping fin, a pressing plate, a connecting piece, a pull rod, a chain, a main shaft and a tension spring, wherein the main shaft is mounted at the center of the base; the spool seat is connected to the main shaft; the shock-absorbing seat is connected to the spool seat; the spool seat and the shock-absorbing seat rotate simultaneously along with the main shaft; the tension spring seat is mounted at one end of the base and fastened through a bolt; the screw is mounted on the tension spring seat; the tension spring is connected to the screw and the other end of the tension spring is connected to the chain; the other end of the chain is connected to the connecting piece; and the connecting piece is mounted on the pull rod. The damped pay-off device is simple, compact and rational in structure, small in floor area and low in cost, convenient for mounting and replacing the spool wheel, steady in paying off, capable of keeping straight in paying off, and not easy to cause breakage.

Description

technical field [0001] The invention relates to a damping type pay-off device, in particular to a wire-drawing machine passive pay-off, and belongs to the technical field of wire-drawing machine equipment. Background technique [0002] In the prior art, in the metal wire drawing production process, the wire-drawing mechanism of the metal wire-drawing machine adopts the I-shaped wheel for unwinding, and the power of the I-shaped wheel for unwinding is realized by the power of the wire-drawing machine, which is passive wire-releasing. The I-shaped wheel has a large resistance due to its own weight. From the full shaft to the empty shaft at the beginning of the I-shaped wheel pay-off, the resistance becomes smaller and smaller, which makes the dynamic tension of the metal wire from large to small during the pay-off process, so that The elongation of the metal wire is uneven; at the same time, the metal wire is easy to break when paying off at high speed. Due to the inertial eff...

The I-shaped wheel has a large resistance due to its own weight. From the full shaft to the empty shaft at the beginning of the I-shaped wheel pay-off, the resistance becomes smaller and smaller, which makes the dynamic tension of the metal wire from large to small during the pay-off process, so that The elongation of the metal wire is uneven; at the same time, the wire is easy to break when paying off at high speed. Due to the inertia, a large amount of metal wire is released to form a mixed line, which not only wastes raw materials but also causes production stagnation.
