Abstract
A cutting-off mechanism of a reinforcing bar hoop bending machine comprises a shearing base, a brake motor, an eccentric shaft and a shearing arm. The brake motor is in driving connection with the eccentric shaft, the front end of the shearing arm is rotationally supported to the shearing base to form a pivot point, the rear end of the shearing arm is equipped with a slideway along the length direction thereof, and a slide block slidably arranged in the slideway is rotationally connected with the eccentric end of the eccentric shaft so as to drive the shearing arm to swing. The technical scheme resolves problems that assembly volume is large and manufacturing and maintenance cost are high because the existing cutting-off mechanism is incompact in structural design.
Description
Technical field
The utility model relates to and is used for the stirrup bender (being about to the machining equipment that bar bending becomes different shape and specification) of moment reinforcement in the building trade, relate in particular to a kind of bar cutting mechanism of stirrup bender, this shut-off mechanism is specially adapted in the digital control steel bar hoop bender.
Background technology
The framework of steel reinforcement of a large amount of use all size reinforcement fabrications improves the intensity of building in the building trade.Stirrup bender is the machining equipment that the wire rod reinforcing bar is made into all size and shape.Stirrup bender generally is made up of feed mechanism, straightening mechanism, haulage gear, bending mechanism and shut-off mechanism.Feed mechanism promptly quits work after reinforcing bar is sent into stirrup bender, reinforcing bar is under the traction of haulage gear, at first aligned, be bent mechanism then and bend to default shape, promptly can be used to assemble framework of steel reinforcement after the reinforcing bar that bends to definite shape is at last cut off by shut-off mechanism by straightening mechanism.
Shut-off mechanism mainly is made of braking motor, reductor, eccentric shaft, linking arm and shear arm in the prior art, wherein, shear arm is fulcrum with its front end to the overhanging rotating shaft of establishing, and rotational support is in the bottom that shut-off mechanism is sheared base, and the front end of shear arm sets firmly a movable blade; The rear end of shear arm is rotationally connected through the eccentric end of linking arm and eccentric shaft.
During work, motor via reducer drives eccentric shaft and rotates, and swings up and down thereby drive the linking arm that is rotationally connected with the eccentric shaft eccentric end, when linking arm is upwards swung, the movable blade that drives the shear arm front end moves downward, and movable blade cooperates shear reinforcement with the dead knife that is fixed on the shearing base.After finishing shear action, the eccentric end of eccentric shaft continue to drive linking arm to lower swing, and then the movable blade that drives the shear arm front end moves upward, and forms sheared edge with dead knife again, enters shearing condition next time, repeats shear action with this.
Above-mentioned cut-out structure has been used for many years, but facts have proved still to come with some shortcomings, mainly is owing to the eccentric end of shear arm by the relative eccentric shaft of linking arm is rotationally connected, and makes that the volume of assembly structure is bigger, structure is not compact, and manufacturing and maintenance cost are all higher.
Therefore, the utility model provides a kind of shut-off mechanism of stirrup bender, to remedy deficiency of the prior art from improving the prior art angle.
Summary of the invention
The utility model provides a kind of shut-off mechanism of stirrup bender, and its purpose mainly is that to solve existing shut-off mechanism structural design not compact, causes assembling that volume is big, manufacturing and maintenance cost problem of higher.
For achieving the above object, the technical solution adopted in the utility model is: a kind of shut-off mechanism of stirrup bender, comprise and shear base, braking motor, eccentric shaft and shear arm, described braking motor and eccentric shaft are in transmission connection, and the front end rotational support of described shear arm forms fulcrum in shearing on the base; Its length direction of upper edge, rear end of described shear arm is offered a slideway, and sliding in this slideway is provided with sliding shoe; The eccentric end of described sliding shoe and described eccentric shaft is rotationally connected, and drives the shear arm swing with this.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described sliding shoe both sides convex with projection, and corresponding projection offers groove on the inwall of described slideway, and described projection is embedded in the groove and is slidingly matched, and constitute sliding shoe and slideway is slidingly matched with this.
2, in the such scheme, described sliding shoe is provided with through hole, and the eccentric end of eccentric shaft is arranged in this through hole, constitutes with this to be rotationally connected.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because adopting, the utility model offers slideway along its length direction in the rear end of shear arm, and the sliding shoe that in this slideway, is slidingly connected, the eccentric end of this sliding shoe and eccentric shaft is rotationally connected, making eccentric shaft drive this sliding shoe reciprocatingly slides along slideway, thereby driving the movable blade that is fixed on the shear arm front end moves up or down, cooperate with dead knife, finish shear history.
2, because the utility model adopts sliding shoe that eccentric end and the shear arm of eccentric shaft are rotationally connected, its structural design compactness, assemble less, and consumable accessory replacing and easy to maintenance, manufacturing and maintenance cost are all lower.
