Abstract
The utility model discloses a traction device of a steel bar numerical control bending hoop machine. The traction device of the steel bar numerical control bending hoop machine comprises a base and traction wheel groups. Each group of traction wheels comprises two traction wheels which are arranged up and down. An axle of each traction wheel cooperates with the base in a rotating manner. A wheel seat is arranged on the axle of each traction wheel. Each traction wheel is fixed on each wheel seat through a screw. One end of the axle penetrates out of the traction wheel, and a nut used for fixing the traction wheel on the wheel seat in a pressing mode is arranged on the end portion of the axle in a threaded manner, so that fastening force in axial direction of the traction wheel is increased. And the bearing vibration of the nut is little because the nut is arranged on the shaft of the traction wheel. The nut can not loosen in working, so that axial movement of each traction wheel is effectively prevented and long-term, stable and reliable work of the traction device is ensured.
Description
Technical field
The utility model relates to a kind of reinforcing bar production equipment, particularly a kind of steel bar numerical control hoop bending machine.
Background technology
Steel bar numerical control hoop bending machine of the prior art generally comprises reinforcing bar draw-gear, steel bar straightening device, bending device for rebars and steel bar cut-off device, the reinforcing bar draw-gear is arranged at before the steel bar straightening device, plays a part reinforcing bar imported steel bar straightening device and drive reinforcing bar to advance.
In the prior art, the reinforcing bar draw-gear generally is comprised of two pairs of traction wheels that are arranged in parallel, two traction wheels of every centering become up and down over against layout, traction wheel is fixed by screws on the installation seat plate, the rotating shaft of traction wheel is fixedly connected with installation seat plate, rotating shaft is connected with motor by transmission mechanism again, and roller end does not pass traction wheel.The reinforcing bar draw-gear of this structure does not have position-limit mechanism in the axial direction between traction wheel and the rotating shaft, traction wheel is fixed in by screw and realizes the location axial location on the mount pad in the axial direction.Because haulage gear is stressed larger at work, the vibration of traction wheel is also larger, and the screw of fixed traction wheel occurs loosening under effect of vibration easily, thereby cause traction wheel to move along rotating shaft, up and down traction wheel dislocation, reinforcing bar can skid off the traction race, job failure occurs.
Therefore, need to improve digital control hoop bender of the prior art, its traction wheel can not moved axially, guarantee its steady operation.
The utility model content
In view of this, the purpose of this utility model provides a kind of steel bar numerical control hoop bending machine draw-gear, and it can guarantee that traction wheel can not move axially at it, and working stability is reliable, and the traction wheel that can solve existing draw-gear existence moves axially problem.
The utility model steel bar numerical control hoop bending machine draw-gear, comprise pedestal and traction wheels, every group of traction wheel comprises two up and down over against the traction wheel of arranging, wheel shaft and the pedestal of described traction wheel are rotatably assorted, be fixedly installed wheeled base on the described wheel shaft, described traction wheel is fixed by screws on the wheel seat, and an end of described wheel shaft passes traction wheel and wheel shaft end threaded engagement and is useful on traction wheel is pressed solidly nut on wheel seat.
Further, described wheel shaft end is provided with the nut of two arranged superposed;
Further, between adjacent two traction wheels, be provided with the reinforcing bar guiding tube that is fixedly connected with pedestal;
Further, described traction wheels are parallel two groups of being arranged in juxtaposition.
The beneficial effects of the utility model: the utility model steel bar numerical control hoop bending machine draw-gear, it is provided with the nut that compresses traction wheel at wheel shaft, increased the power that axially fastens of traction wheel, and nut is arranged on the wheel shaft, its vibration of bearing is little, nut can not become flexible in the work, can prevent effectively that therefore traction wheel is mobile vertically, can guarantee the work of draw-gear long time stability.

Fig. 1 is steel bar numerical control hoop bending machine draw-gear front view;
Fig. 2 is along the cutaway view of A-A among Fig. 1;
Fig. 3 is the left view of reinforcing bar guiding tube.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, present embodiment steel bar numerical control hoop bending machine draw-gear, comprise pedestal 1 and traction wheels, every group of traction wheel comprises two up and down over against the traction wheel 2 of arranging, wheel shaft 3 and the pedestal 1 of described traction wheel 2 are rotatably assorted, be fixedly installed wheeled base 4 on the described wheel shaft 3, described traction wheel 2 is fixed on the wheel seat 4 by screw 5, and an end of described wheel shaft 3 passes traction wheel 2 and wheel shaft 3 end thread are combined with for the nut 6 that traction wheel 2 is pressed solidly on wheel seat 4.
This steel bar numerical control hoop bending machine draw-gear, it is provided with the nut 6 that compresses traction wheel at wheel shaft 3, increased the power that axially fastens of traction wheel 2, and nut 6 is arranged on the wheel shaft 3, its vibration of bearing is little with respect to the screw 5 that is arranged on the traction wheel 2, nut 6 can not become flexible in the work, can prevent effectively that therefore traction wheel 2 is mobile vertically, can guarantee the work of draw-gear long time stability.
As the improvement to present embodiment, 6, two nuts 6 of nut that the end of described wheel shaft 3 is provided with two arranged superposed can apply axial pressing force mutually in rundown process, eliminate thread pitch, can play the effect that prevents nut loosening, can guarantee further that traction wheel 2 can not move axially.Certainly in different embodiments, also can lock pin be set in wheel shaft 3 ends, loosening to prevent that nut 6 from occuring after excessively working long hours.
As the improvement to present embodiment, between adjacent two traction wheels, be provided with the reinforcing bar guiding tube 7 that is fixedly connected with pedestal 1, reinforcing bar guiding tube 7 can play the guiding role to reinforcing bar, makes reinforcing bar accurately enter smoothly next traction wheels from last traction wheel group.
As the improvement to present embodiment, described traction wheels are parallel two groups of being arranged in juxtaposition, and arrange two groups enough tractive force can be provided, and the power of simultaneously draw-gear consumption is lower.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
