Multifunctional reinforcing steel bar automatic hoop-bending machine bending from two ends of reinforcing steel bar

Abstract

The invention discloses a multifunctional reinforcing steel bar automatic hoop-bending machine bending from the two ends of a reinforcing steel bar. The multifunctional reinforcing steel bar automatic hoop-bending machine comprises a machine frame, wherein a traction mechanism, a straightening mechanism, a shearing mechanism and a bidirectional bending mechanism are axially arranged on the machine frame along the upstream of the reinforcing steel bar sequentially; a multifunctional mechanism is also arranged on the machine frame on the upstream of the bidirectional bending mechanism; the multifunctional mechanism comprises a compression moving mechanism, a material-pushing mechanism and an overall retraction mechanism; the material-pushing mechanism is used for pushing a hoop bar which is formed in a bending way; and the overall retraction mechanism is used for pulling the compression moving mechanism and the material-pushing mechanism into the inner side of a machine shell panel or pushing the compression moving mechanism and the material-pushing mechanism to a working position. The multifunctional reinforcing steel bar automatic hoop-bending machine has the beneficial effects that the other end of the reinforcing steel bar which is sheared by the shearing mechanism can be bent, long hoop bar products with hooks at the two ends can be bent rapidly and at one time, the requirement of production is met, and the production efficiency is high. The multifunctional reinforcing steel bar automatic hoop-bending machine is simple in structure, low in cost, high in adaptability, wide in production range, and has complete functions.

Description

technical field [0001] The invention relates to an automatic hoop bending machine for steel bars, in particular to a multifunctional automatic hoop bending machine for steel bars that bends from both ends of the steel bars. Background technique [0002] The steel bar automatic bending machine is a steel bar automatic processing equipment that bends straight steel bars into stirrups of a certain shape. With the rapid development of economic construction, the automatic hoop bending machine for steel bars has been widely used. The automatic hoop bending machine for steel bars in the prior art includes: a traction mechanism, a straightening mechanism, a shearing mechanism and a bending mechanism arranged in sequence according to the axis. [0003] The production process of the above-mentioned prior art steel bar automatic bending hoop machine is: the traction mechanism pulls and moves the coiled steel bar to the upstream direction; the straightening mechanism straightens the be...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned prior art steel bar automatic bending machine has the following defects: the prior art steel bar automatic bending machine can only be bent into various shapes from one end of the steel bar to the steel bar along the upstream moving direction at different positions, such as triangle, square, Round and other shapes, but the steel bar cannot be bent from the other end of the steel bar, that is, the existing automatic steel bar bending machine cannot produce stirrups with bending requirements at both ends of the steel bar; The steel bar bent at one end is cut on the automatic hoop bending machine, and the other end of the steel bar is manually bent

Therefore, the prior art steel bar automatic hoop bending machine has the defects of narrow production range, inability to quickly bend hoop products with hooks at both ends, unable to meet the needs of production, high production cost, and labor-intensive and time-consuming defects.
