Abstract
The utility model discloses a driving wheel of a cold pipe-bending machine. The circumferential surface of the driving wheel is in an arc groove shape in the circumferential direction, mould pieces which are arc in whole are arranged in arc grooves of the driving wheel and are matched with the arc grooves of the driving wheel, the central angle of each mould piece is greater than or equal to 180 degrees, the section of each mould piece is a semicircular groove, and the inner diameter of each semicircular groove is equal to the outer diameter of a pipe to be bent. According to the driving wheel, the number of driving wheels can be decreased by additionally installing the mould pieces, and therefore cost is reduced, manufacturing time of the driving wheel is shortened, and work efficiency is improved.
Description
Technical field
The utility model relates to cold bending technical field, especially a kind of cold bending machine driving wheel processing method and cold bending machine driving wheel.
Background technology
In existing cold bending machine, driving wheel is the critical piece of pipe processing.Cold bending driving wheel periphery is along circumferential curved groove shape, the cross section semicircular in shape of this arc groove.Add man-hour, pipe to be bending is fit in this arc groove, driving wheel completes the work of pipe bending in rotation.
Driving wheel cost of manufacture is high and fabrication cycle is long, pipe specification and radius of machining that a kind of driving wheel is processed are constant, in the time of need to processing the pipe of different size, need again to make different driving wheels, cause existing forming mill cost when the identical pipe of processing specification difference, radius higher, and the making mold time is long, mold cost is higher, and whole efficiency is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of method of cold bending machine driving wheel reducing.
For achieving the above object, the utility model discloses a kind of cold bending machine driving wheel, its periphery is along circumferential curved groove shape, the curved tyre shoe of entirety is installed in the arc groove of described driving wheel, the arc groove of tyre shoe and driving wheel is suitable, the central angle of tyre shoe is more than or equal to 180 degree, the cross section semicircular in shape groove of tyre shoe, and the internal diameter of this semi-circular recesses is identical with the external diameter of pipe to be bending.
Described tyre shoe is connected in the arc groove of driving wheel in the mode being spirally connected or weld.
The utility model can reduce by installing the mode of tyre shoe additional the quantity of making driving wheel, thereby reduces costs, and saves the time of making driving wheel, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing at A place in Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the supporting cold bending machine driving wheel reducing processing method of the utility model is carried out successively according to the following steps:
First step is to choose suitable tyre shoe pipe, and the internal diameter of the arc groove 2 of tyre shoe tube outer diameter and existing cold bending machine driving wheel 1 is suitable, and the internal diameter of tyre shoe pipe is less than the external diameter 6-10 millimeter of pipe to be bending.
Second step is that the tyre shoe pipe of choosing is bent into the tyre shoe pipeline section that is not less than 180 degree in forming mill; The concrete angle that bends also can be adjusted according to the angle of intending bending bend pipe, when intending bending the angle of bend pipe when larger, can corresponding increase tyre shoe pipe bend angle, make the central angle of the tyre shoe pipeline section of producing be greater than the central angle of intending bending bend pipe.
Third step is that the tyre shoe pipeline section after bending is cut away half along axis direction symmetry, gets the half tyre shoe pipeline section in the close tyre shoe pipeline section center of circle as tyre shoe 3, the cross section semicircular in shape groove shape of tyre shoe 3.
The 4th step is tyre shoe 3 to be fitted in the arc groove 2 of described driving wheel 1 and to be spirally connected or the mode of spot welding is fixed; Be spirally connected or the mode of spot welding is easy-to-dismount connected mode, to facilitate the tyre shoe 3 of changing different size when the bend pipe of processing different-diameter.
The 5th step is cold bending machine driving wheel 1 lathe on the whole of tyre shoe 3 to be installed, tyre shoe 3 semi-circular recesses are carried out to turning processing, makes the internal diameter of semi-circular recesses 4 of tyre shoe 3 identical with the external diameter of pipe to be bending.
This method step is easy, and after this method is processed, the radius of machining of cold bending machine driving wheel just can adapt to the pipe to be processed of different-diameter, bend pipe to be bending is fit in the arc groove of tyre shoe and can carries out bending process.Owing to using the present invention can reduce the quantity of making driving wheel, therefore can reduce costs, increase work efficiency.
As depicted in figs. 1 and 2, the periphery of cold bending machine driving wheel 1 of the present invention is along circumferential curved groove shape, the curved tyre shoe 3 of entirety is installed in the arc groove 2 of described driving wheel 1, tyre shoe 3 is suitable with the arc groove 2 of driving wheel 1, the central angle of tyre shoe 3 is more than or equal to 180 degree, the cross section semicircular in shape groove 4 of tyre shoe 3, the internal diameter of this semi-circular recesses 4 is identical with the external diameter of pipe to be bending.Described tyre shoe 3 is connected in the arc groove 2 of driving wheel 1 in the mode being spirally connected or weld.
In the time of need to bending the pipe of different-diameter, same flexure radius, need not make the different driving wheel of pipe diameter 1, only the tyre shoe being made into according to method in the present embodiment 3 need to be packed in the arc groove 2 of driving wheel 1.During pipe bending, pipe to be bending is put into semicircle (arc) groove 4 of tyre shoe 3, can be bent work.
Above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify or be equal to replacement the present invention, and not departing from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
