Abstract

The invention relates to a back conveying and bending mechanism of a reinforcing steel bar automatic bending machine, which comprises a back conveying drive traction wheel, a back conveying driven traction wheel, a back conveying press wheel, a back conveying stand and a telescopic cylinder, wherein the back conveying stand is installed on a stand, and the upper part of the back conveying stand is provided with the back conveying press wheel which is connected with a back conveying press mechanism; the lower part of the back conveying stand is provided with a back conveying power shaft and a back conveying driven traction wheel shaft; the end parts of the back conveying power shaft and the back conveying driven traction wheel shaft are respectively provided with a back conveying traction wheel and the back conveying driven traction wheel which are positioned under the back conveying press wheel; the back conveying stand is connected to a telescopic unit; the back conveying power shaft is connected with a rotating drive unit; and a power transfer device is arranged between the back conveying power shaft and the back conveying driven traction wheel shaft. The invention expands the function of the bending machine and processes more stirrup products once; when the reinforcing steel bar rotates, the product does not rotate; and the bending machine not only bends a coil rod reinforcing steel bar, but also rapidly bends the stirrup product bent by a straight reinforcing steel bar commonly used by engineering.

Description

technical field [0001] The invention relates to an automatic steel bar hoop bending machine, in particular to a return bending mechanism of the steel bar automatic hoop bending machine. Background technique [0002] With the rapid development of economic construction, the automatic processing equipment for stirrups - the automatic bending machine for steel bars has been widely used. The prior art steel bar automatic hoop bending machine comprises several traditional mechanisms such as traction mechanism, straightening mechanism, bending mechanism and shearing mechanism. With the development of production, there are new requirements for the efficiency and size of curved steel products. [0003] The production process of the above-mentioned prior art hoop bending machine is: after all the bending angles are bent, a shearing action is performed to complete the processing of a stirrup product. Restricted by the processing technology, the size of the stirrup side that can be be...
