Anti-torsion steel bar feeding mechanism

Abstract

The invention discloses an anti-torsion steel bar feeding mechanism, which comprises a frame and two straightening wheel sets, wherein a traction mechanism is arranged between the two straightening wheel sets and is higher than the two straightening wheel sets; the traction mechanism comprises a main drive wheel and a pressing wheel; a steel bar traction V-shaped groove is formed in the outer edge of the main drive wheel; the outer edge of the cross section of the pressing wheel is outwardly projected ladder-shaped; the pressing wheel is arranged on a pressing mechanism; the pressing mechanism is arranged on the frame; the two straightening wheel sets comprise a plurality of straightening wheels and straightening wheel pressing mechanisms respectively; a trailed steel bar wound on the main drive wheel is pressed to be arc-shaped by the straightening wheels; and the pressing wheel is used for pressing the arc-shaped steel bar. The anti-torsion steel bar feeding mechanism has the beneficial effects that the steel bar is contacted with the arc surface of the main drive wheel, the pressure contact area of the steel bar and the main drive wheel is large, the steel bar is not twisted, and the traction effect is good; and the pressing wheel can be used for tightly pressing the steel bar to prevent slip, rib damage, torsion and asynchronous defect of the steel bar and improve the quality of the finished steel bar. A plurality of steel bars are good in synchronicity, simple in structure and convenient to repair.

Description

technical field [0001] The invention relates to a steel bar feeding mechanism, in particular to a torsion-resistant steel bar feeding mechanism. Background technique [0002] At present, in the production and processing of various steel bars in the construction industry, it is usually necessary to straighten the raw material wire rods and steel bars and then transport them to the processing equipment for further processing. Before the steel bars are sent to the deep processing equipment, the steel bars need to be pulled Mechanism for conveying, and then the straightening mechanism will process the bent steel bars into straight steel bars. [0003] The traction mechanism in the prior art includes: a main driving wheel connected with a motor and a pressure wheel located above the main driving wheel, and the wire rod is pulled and moved between the main driving wheel and the pressure wheel by friction. In order to improve the pulling efficiency of the prior art steel bars, two...

AI Technical Summary

Problems solved by technology

[0004] There are the following defects in adopting the prior art steel bar traction mechanism and straightening mechanism to convey straightened ribbed steel bars: first, when two ribbed steel bars pass between the main drive wheel and the pressure wheel of the traction mechanism at the same time, due to the ribbed steel bar section It is elliptical, and there is a difference in the cross-sectional shape of the two steel bars that enter between the main drive wheel and the pressure wheel at the same time. The same pressure wheel cannot be pressed on two steel bars at the same time, and the pressure on the two steel bars is inconsistent. When the pressing force of the pressing wheel is high, one of the steel bars will be over-pressed and the surface of the steel bar will be damaged, and the steel bar with low pressure will appear torsion, rolling and slipping. The existing technology of the pressing wheel mechanism is difficult to ensure that the two steel bars are driven evenly and stably at the same time. force

Secondly, the feeding mechanism of the prior art adopts a main drive wheel corresponding to a pressing wheel, and the steel bar passes through the tangential direction of the main driving wheel and the pressing wheel, the contact area between the steel bar and the driving wheel is small, the friction force is small, and the traction speed is slow

In addition, the forward direction of the pulled steel bar is a straight line, and it is prone to self-rotation during the feeding process. There is a deformation defect that the bent stirrups have several sides that are not in the same plane due to the torsion of the steel bar during the feeding process.
