Abstract

The invention discloses an automatic hoop bending machine for a straight steel bar. The automatic hoop bending machine structurally comprises a traction mechanism, a shearing mechanism, a bending mechanism and a feeding mechanism. The feeding mechanism comprises a lower feeding wheel and an upper feeding wheel connected with an upper press wheel swing arm. The upper press wheel swing arm comprises a connecting plate, and a connecting shaft and a hinge shaft are arranged at the two ends of the rear side face of the connecting plate respectively in a protruding manner; a piston rod of an air cylinder / oil cylinder is connected with the end of the connecting shaft; the hinge shaft is hinged in a supporting hole in a feeding frame; and the upper feeding wheel is arranged on the front side face of the connecting plate in a protruding manner. The automatic hoop bending machine has the beneficial effects that power is provided for the feeding mechanism and the traction mechanism through one power source; the straight steel bar smoothly enters the traction mechanism from the feeding mechanism and a wire guide mechanism at the inlet end of a rack, and a straightening mechanism which is complex and occupies large equipment space is omitted; a detection plate, combined with a detection switch, in the wire guide mechanism and components related to the detection plate are simple in structure and flexible in action; and materials used for products can be accurately calculated, a reference is provided for scientifically calculating raw materials and tailings, and waste of the steel bar is reduced.

Description

technical field [0001] The invention relates to an automatic steel bar bending hoop machine, in particular to a steel bar automatic hoop bending machine specially used for processing straight steel bars. technical background [0002] The automatic steel bar bending machine is an automatic processing equipment that continuously bends coiled steel bars into different shapes of stirrups. The prior art automatic steel bar bending machine includes: a straightening mechanism, a traction mechanism, a bending mechanism, and a shearing mechanism. [0003] In the prior art, coiled steel bars are usually selected as the raw material of the automatic steel bar bending machine, so a straightening mechanism must be provided at the entrance of the steel bar on the automatic steel bar bending machine to straighten the bent coiled steel bars first. The final straight steel bars are then subjected to subsequent processing. [0004] The above-mentioned prior art steel bar automatic bending ma...
