Anti-torsion traction device for reinforcing bar hoop bending machine

Abstract

The invention discloses an anti-torsion traction device for a reinforcing bar hoop bending machine. The anti-torsion traction device comprises a traction main shaft of which one end is connected with a power device and hinged with and supported on a traction board, a main traction wheel arranged at the other end of the traction main shaft, a compaction wheel positioned above the main traction wheel, and a down-pressing mechanism connected with the compaction wheel, wherein the main traction wheel is arranged between two groups of straightening wheel groups with the same height, so a dragged reinforcing bar passes through the main traction wheel and the two groups of straightening wheel groups and is formed into a cambered shape; and the compaction wheel pressed on the cambered reinforcingbar which is coiled through the main traction wheel. The anti-torsion traction device has the advantages that: the reinforcing bar moves between the main traction wheel and the straightening wheels in a circular arc path, so the reinforcing bar can release stress fully; and torsion can be avoided after the reinforcing bar is straightened and bent. By enlarging a contact area between the reinforcing bar and the main traction wheel, a slipping phenomenon during traction of the reinforcing bar can be avoided and the quality of the reinforcing bar can be improved; and the anti-torsion traction device has the advantages of simple structure, convenience for maintenance, conservation of energy consumption, stable work and low cost.

Description

technical field [0001] The invention relates to a steel bar hoop bending machine, in particular to an anti-twist traction device of the steel bar hoop bending machine. Background technique [0002] The steel bar bending machine is an automatic steel bar processing equipment that bends straight or coiled steel bars into different shapes. The steel bar bending machine includes: traction mechanism, straightening mechanism, bending forming mechanism and shearing mechanism. [0003] figure 1 It is the front view of the traction mechanism of the prior art steel bar hoop bending machine; figure 2 yes figure 1 cutaway view. [0004] Such as figure 1 , figure 2 As shown, the traction mechanism of the steel bar bending machine in the prior art includes: two traction shafts 13 equipped with traction wheels 5 that are arranged side by side with the same structure; Transmission mechanism; above the two traction wheels 5 are respectively provided with a pressing wheel 3, and the p...

Problems solved by technology

[0006] First of all, the coiled steel bar passes through the traction mechanism and the straightening mechanism in a straight line, and the internal stress is not fully released after passing through the above two mechanisms, so the steel bar twists when it enters the bending mechanism for bending; secondly, the compression of the traction mechanism The...
