Abstract
The invention discloses a layering roller wheel. The layering roller wheel comprises a roller wheel body and a roller wheel shaft. The roller wheel body is divided into 3-7 layers in the axis direction of the roller wheel body, the middle layer is fixedly connected with the roller wheel shaft and is a driving layer, and the other layers on the two sides of the middle layer are respectively independent following layers. The following layers and the roller wheel shaft or the cylindrical surface, in the axis direction, of the driving layer are connected through a bearing, and balls are arranged between the surfaces of every two adjacent layers. In the process of bending a large-diameter steel pipe into a bent pipe with a small curvature radius, the internal friction can be reduced, the production speed of the steel pipe is increased, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of steel pipe cold bending equipment, relate in particular to a kind of layering running roller.
Background technology
At present, mostly clod wash technology is that bend diameter is less than the fine steel tube of 100mm, and diameter is greater than 150mm, radius of curvature, and to be less than the steel pipe clod wash of 3000mm very difficult.Along with, the reducing of the increase of caliber and radius of curvature, " internal friction " in bend pipe process enlarges markedly.
As shown in Figure 1, the production of steel pipe concrete bracket is first in the arc-shaped with seamless steel pipe bend pipe on ground, and bend pipe process has been combined by running roller, and steel pipe concrete bracket uses the diameter of seamless steel pipe mostly all more than 150mm.
As shown in Figure 2, running roller of the prior art adopts whole coaxial configuration.Be that running roller carries out unitary rotation around axle center, running roller integral body has identical angular speed, from, on running roller arc surface, different positions has different linear velocities, and the point in cambered surface is nearer apart from running roller axle center, and the speed of acquisition is less, far away apart from running roller axle center, the speed of acquisition is larger.In actual production process, velocity of rotation in the part cambered surface that the upper and lower two ends of running roller contact with steel pipe will be ahead of the fltting speed of steel pipe, velocity of rotation in the part cambered surface contacting with steel pipe in the middle of running roller will lag behind the fltting speed of steel pipe, this can cause steel pipe partial to produce " stretching effect ", while making steel pipe contact with running roller arc surface, produce larger friction simultaneously, noise is larger, is unfavorable for personnel's work.
Summary of the invention
The object of this invention is to provide and a kind ofly can reduce the layering running roller that large diameter steel pipe clod wash becomes the internal friction of small curvature radius bend pipe.
The object of the invention is to be achieved through the following technical solutions:
Layering running roller of the present invention, comprises running roller, rolling axle, and described running roller is divided into a plurality of layerings along described running roller axis direction, and intermediate layer and described rolling axle are fixedly connected as active layers, and other layering of both sides, intermediate layer is independently servo-actuated layer separately.
As seen from the above technical solution provided by the invention, the layering running roller that the embodiment of the present invention provides, because running roller is divided into a plurality of layerings along running roller axis direction, intermediate layer and rolling axle are fixedly connected as active layers, other layering of both sides, intermediate layer is independently servo-actuated layer separately, can reduce the internal friction that large diameter steel pipe clod wash becomes small curvature radius bend pipe.

The specific embodiment
To be described in further detail the embodiment of the present invention below.
Layering running roller of the present invention, its preferably the specific embodiment be:
Comprise running roller, rolling axle, described running roller is divided into a plurality of layerings along described running roller axis direction, and intermediate layer and described rolling axle are fixedly connected as active layers, and other layering of both sides, intermediate layer is independently servo-actuated layer separately.
Described active layers is fixedly connected with by pin with rolling axle, and described servo-actuated layer adopts bearing to be connected with described rolling axle or described active layers between the face of cylinder of axis direction.
Between the aspect of adjacent two layers, ball is set.
Described running roller is divided into 3 to 7 layerings along described running roller axis direction.
Layering running roller of the present invention, can reduce the internal friction that large diameter steel pipe clod wash becomes small curvature radius bend pipe.
Specific embodiment:
As shown in Figure 3, the overall structure of running roller is carried out to cutting along running roller axis direction, be divided into some layerings of independent rotation separately, only allow intermediate layer as driving wheel, along with central shaft rotates, intermediate layer is referred to as again " active layers "; Each layering of other of central core both sides, does not rotate with central shaft, independence and freedom rotation separately, and each layer up and down except intermediate layer, is referred to as again " servo-actuated layer ".
Active layers and central shaft are that pin is fixedly connected with; Between servo-actuated layer and central shaft (or active layers axis direction face of cylinder), adopt bearing to connect.
For reducing the frictional force between the aspect of adjacent two layers, ball is set between each layer.
Structural design of the present invention, when bend pipe, intermediate layer becomes the driving layer that drives steel pipe to move ahead along steel pipe axis.Remaining upper and lower servo-actuated layer, under the drive of tube fraction power, rotates with identical linear velocity.Upper and lower servo-actuated layer only plays the position-limiting action to steel pipe, does not play driving effect, and the contact-making surface of running roller drive part and steel pipe only limits to the intermediate layer of running roller, i.e. this section of circular arc of one section of circular arc, and running roller is less to the semidiameter of running roller axis, so it is very little to rub.Each layering of both sides, intermediate layer, with the linear velocity rotation same with steel pipe, so the frictional force of each layering and steel pipe support is also very little.This is divided into running roller structure, has reached the object that has reduced bend pipe frictional force, and the noise that while and then reduction friction cause, improves workman's work situation.Of the present invention simple and practical, when component processing and installation, all easily operate, can accelerate the speed of production of steel pipe, enhance productivity.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
