Abstract

The utility model relates to a reinforcing bar cutting and bending machine which is a machine for cutting and bending reinforcing bars to required forms. The utility model is mainly composed of a cutting work head, a bending work head and a machine body, wherein, the bending work head uses a rotary actuator as the power, the rotating shaft of the rotary actuator directly drives a work rotating disk on which a core pin and a rotating pin are arranged, an unprocessed reinforcing bar is put between the two pins, when the rotating shaft drives the work rotating disk to rotate, the rotating pin bends the unprocessed reinforcing bar to the required form. The utility model has the advantages of simple and compact structure, steady work, high efficiency and low noise in use, and is widely used for processing various reinforcing bars.

Description

Reinforcing bar cutting and bending machine

The utility model is a kind of machinery of processing reinforcing bar, belongs to the technical field of building machinery.

General motor-driven steel bar processing machinery is by the mode branch of its transmission, mainly contain two kinds, a kind of is mechanical drive mode, it is the transmission by gear pair, drive that eccentric mechanism cuts and crooked, the weight ratio of this operating mechanism self is bigger, consumptive material is also many, the noise that sends during work is also bigger, carrying and use are not too convenient, and another kind is hydraulicdriven mechanism, and this mechanism promotes outside actuating mechanism by moving back and forth of the piston rod in the hydraulic cylinder, move back and forth, cut off and crooked purpose to reach.Because the piston rod in this hydraulic gear is with straight-line, if want moment reinforcement, also must add outside rotating mechanism, therefore increased the complexity of overall setup virtually again.

Goal of the invention of the present utility model provides a kind of reinforcing bar that utilizes oscillating motor to carry out crooked work and cuts, bends dual-purpose machine.

Reinforcing bar of the present utility model cuts, curved dual-purpose machine is mainly by cutting off working head (1), crooked working head (2), body (3) is formed, crooked working head (2) be positioned at body (3) above, cut-out working head (1) is positioned at the side of body (3).Adopt oscillating motor (2-2) source that is used as power as the crooked working head (2) of crooked operating mechanism, in the rotating shaft (2-21) of oscillating motor (2-2), be fixed with working rotary table (2-1), on working rotary table (2-1), be provided with centrepin (2-11) and rotational pin (2-12).Wherein oscillating motor (2-2) comprises rotating shaft (2-21), cylinder body (2-22), moving plate (2-23), stator (2-24), wherein cylinder body (2-22) is cylindrical, and rotating shaft (2-21) is located on the longitudinal center line of cylinder body (2-22), and moving plate (2-23) is fixed in the rotating shaft (2-21), stator (2-24) is fixed on the cylinder body (2-22), on the sidewall that advance, oil drain out (2-25) is located at cylinder body (2-22) and lay respectively at the both sides of stator (2-24).The operation principle of this machine and the course of work are: at first reinforcing bar is stuck between the centrepin and rotational pin on the rotating disk, the rear end of reinforcing bar is supported (5) by adjustable steel bar and is withstood, when pressure oil advancing from cylinder body one side, when oil drain out enters cylinder body, pressure oil promotes moving plate in cylinder body, thereby driving rotating shaft rotates, when rotating shaft is rotated, the working rotary table that drive is fixed in the rotating shaft rotates, because the rotation of working rotary table, the rotational pin that is fixed on the working rotary table is that rotate in the center of circle with the axle center of rotating shaft with rotating disk together just, simultaneously will be at the bar bending between rotational pin and the centrepin.

Adopt reinforcing bar of the present utility model to cut, bend dual-purpose machine, its advantage is, the source because the employing oscillating motor is used as power, rotate directly driving working rotary table by the rotating shaft of this hydraulic cylinder, and moment reinforcement, so high efficiency, the course of work is steady, the total structure of complete machine more becomes simply, and compact conformation.Owing to adopt the mode of hydraulic pressure to drive, the noise at scene is very little during work, has improved workman's working environment effectively in addition.

Fig. 4 is the vertical view of working rotary table, comprising processed reinforcing bar (4).

Reinforcing bar of the present utility model is cut, curved dual-purpose machine embodiment is as follows:

Cut off working head (1) and adopt the hydraulic pressure of prior art to cut off working head, this partial fixing is in the side of body (3).Adjustable steel bar supports (5), and to be fixed on the working rotary table (2-1) on top of body (3) other, crooked working head (2) be positioned at body (3) above, this part is made the power source that drives by oscillating motor.Working rotary table (2-1) is made by steel plate, the central authorities of its rotating disk are fixed in the rotating shaft (2-21) of oscillating motor, on working rotary table, be provided with a centrepin (2-11) and a rotational pin (2-12) in addition, these two pins are made by high strength steel, centrepin is positioned at the center of working rotary table, rotational pin is positioned on the plane of working rotary table, can decide according to the diameter of processed reinforcing bar at a distance of the distance of centrepin.Reinforcing bar for the ease of processing all size and various flexibility, several locating holes at a distance of the centrepin different distance can be set on the plane of working rotary table, according to different requirements, rotational pin is fixed in certain locating hole, so just can be according to various needs, the reinforcing bar of processing all size.Oscillating motor (2-2) is cylindrical, moving plate (2-23) is fixed in the rotating shaft (2-21), can slide between the inwall of the outer end of moving plate and cylinder body (2-22), stator (2-24) is fixed on the cylinder body (2-22), can slide between stator and the rotating shaft (2-21).The both sides that advance, oil drain out (2-25) are positioned at the stator on the cylinder body.According to the above, just can be made into reinforcing bar of the present utility model and cut, bend dual-purpose machine.
