Passive elevated pay-off mechanism of dry-type wire drawing machine

Abstract

The invention relates to a passive elevated pay-off mechanism of a dry-type wire drawing machine, specifically is used for elevated pay-off in the dry-type wire drawing machine and belongs to the technical field of metalware production. The mechanism comprises an upright, a crawling part, a wire outlet wheel, transition wheels, a swing arm, a wire inlet columnar pipe, an air cylinder, an electric box, a flower basket frame and tensioning wheels. The crawling part is mounted at a lower end of the upright, a snarl travel switch, the wire outlet wheel and the electric box are mounted on the center portion of the upright, a rotary shaft is arranged at an upper end of the upright, and a swing arm rotary closing switch is fixed at the top of the upright. An inner end of the swing arm is mounted on the rotary shaft, the wire inlet columnar pipe is mounted on a lower plane of an outer end of the swing arm, the tensioning wheels are mounted in the swing arm above the wire inlet columnar pipe, one end of the air cylinder is mounted on the swing arm, and the other end of the air cylinder is mounted on the upright. The passive elevated pay-off mechanism of the dry-type wire drawing machine is simple, compact and rational in structure, the machine can be controlled to halt when metal wires are snarled and knotted during wire drawing to avoid wire mixing and long-time production stagnation, and continuous flower basket frame pay-off can be realized through swing arm parts, so that time is saved and working efficiency is improved.

Description

technical field [0001] The invention relates to a passive high-position pay-off mechanism for a dry-type wire drawing machine, in particular to a high-position pay-off mechanism for a dry-type wire drawing machine, and belongs to the technical field of metal product production. 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 to pay off the wire. The I-shaped wheel has a relatively large resistance due to its own weight. Shaft, the resistance keeps getting smaller, so that the metal wire produces a dynamic tension 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 be knotted when the wire is paid out at high speed, due to inertia The effect causes a large number of metal wires to be released to form a mixed line, which not only wastes raw materials but a...
