Description

Hoop bending machine for reinforcing steel bars

Technical Field

The utility model relates to a curved hoop equipment technical field of reinforcing bar, especially a curved hoop machine of reinforcing bar.

Background

The reinforcing steel bar hoop bending machine is used for manufacturing a concrete framework and bending reinforcing steel bars to form a closed shape, in the prior art, a general alternating current motor of the reinforcing steel bar hoop bending machine is used as a power source, the output rotating speed is high in the operation process, the inertia force is large when the reinforcing steel bars are bent, the bending angle is not easy to control, a multi-stage speed change mechanism is usually needed for speed reduction, the cost of the machine is increased, in addition, the forward rotation and the reverse rotation of the alternating current motor need to be realized by phase change of current through a plurality of alternating current contactors, the frequent suction failure rate of the alternating current contactors is high, and therefore the existing reinforcing steel bar hoop bending machine needs to be further improved.

SUMMERY OF THE UTILITY MODEL

To the above defect, the utility model discloses the main technical problem who solves provides a curved hoop machine of reinforcing bar that operates steadily, the fault rate is low.

In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a steel bar hoop bending machine, includes the quick-witted box, and quick-witted box upper portion distributes has the work disc, and the center of work disc is connected with the king pin, and the periphery of work disc is connected with the bending pin, the work disc is connected with first axis, first axis articulates the mount in quick-witted box, and its one end stretches out outside the quick-witted box, and first axis is connected with the second axis through the gear train, and the second axis also articulates the mount, and the second axis passes through hydraulic motor and drives, and hydraulic motor meets with hydraulic oil pump.

In the technical scheme, an encoder connecting shaft extends out of the bottom of the second middle shaft at a concentric position, and the encoder connecting shaft is connected with an encoder through a hose.

In the technical scheme, the bottom of the case body is provided with a wheel body.

In the technical scheme, the center pin, the bending pin and the working disc are in plug-pull fit.

In the technical scheme, the first middle shaft and the second middle shaft are hinged and matched on the fixed frame through bearings.

The utility model has the advantages that: the utility model discloses a hydraulic motor drive, because the rotational speed of hydraulic motor output is lower, compare its power variable speed structure simpler with prior art, simplified the inside overall arrangement of machine, because the power of hydraulic motor output has better steadiness ability, can improve the effect that the reinforcing bar was bent, hydraulic motor's positive and negative rotation passes through hydraulic oil pump direct control, has avoided the fault phenomenon that ac contactor produced among the prior art.
