Correcting stirrup twisting device of automatic steel bar bending machine

Abstract

The invention discloses a correction hoop twisting device of an automatic rebar hoop bending machine. The correction hoop twisting device comprises a rack of the hoop bending machine, and a correction plate arranged on the rack, wherein the correction plate is positioned outside the working face of a bending handpiece at the front of the hoop bending machine; the gap between the inner side face of the correction plate and the working face of the bending handpiece of the hoop bending machine is slight greater than the thickness of a hoop. The correction hoop twisting device has the beneficial effects that the correction hoop twisting device overcomes the defects in the prior art, the defect that a rebar rotates in the traction feed-in in the prior art is overcome, the twisting of the hoop is limited directly, the correction hoop twisting device has a correction twisting way, the structure is simple, the performance is reliable, the installation is convenient, the position of the correction plate is adjustable, the applicable scope is wide, and the finished hoops after processing can be enabled to be in a vertical plane reliably.

Description

technical field [0001] The invention relates to an automatic steel bar bending machine, in particular to a correcting stirrup twisting device of the automatic steel bar bending machine. Background technique [0002] At present, the automatic steel bar bending machine is an automatic equipment used to bend coiled steel bars into various shapes of stirrups for construction. The automatic steel bar bending machine has been widely used in the field of construction steel bar processing. In order to improve the adhesion of steel bars in concrete structures, the construction industry uses hot-rolled ribbed tertiary steel bars instead of smooth round coil steel bars, that is, ribbed steel bars are distributed with convex ribs on the surface, and their cross-sections are elliptical. [0003] figure 1 It is a front view of a hoop bending machine in the prior art, in which a schematic diagram of bending a steel bar into a stirrup by a bending machine head is shown in the figure; fig...

AI Technical Summary

Problems solved by technology

In the prior art, the head end 6a of the stirrup and the end 6b of the stirrup are not in a vertical plane, that is, the head end 6a of the stirrup is inclined to the outside of the end 6b of the stirrup. The reason for the above phenomenon is: During the process of pulling steel bars, the advancing direction of the pulled steel bars is a straight line, and the steel bars are prone to self-rotation during the feeding process. The end and the end of the stirrup are not in the same vertical plane, that is, the head end of the bent stirrup is inclined to the outside of the end of the stirrup, and there are unqualified stirrups, which cannot meet the engineering requirements
