Description
Technical field
The present invention 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.The periphery circumferentially curved groove-like of cold bending driving wheel, the cross section semicircular in shape of this arc groove.Add man-hour, be fit into by pipe to be bending 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, the pipe specification that a kind of driving wheel is processed and radius of machining are constant, need to need again during the pipe processing different size to make different driving wheels, cause existing forming mill cost when processing the pipe that specification is different, radius is identical higher, and the making mold time is longer, mold cost is higher, whole efficiency is lower.
Summary of the invention
The object of the present invention is to provide a kind of cold bending machine driving wheel reducing processing method.
For achieving the above object, cold bending machine driving wheel reducing processing method of the present invention is carried out successively according to the following steps: first step chooses suitable tyre shoe pipe, tyre shoe tube outer diameter and existing cold bending machine driving wheel the internal diameter of arc groove suitable, 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 chosen is bent into the tyre shoe pipeline section being not less than 180 degree in forming mill; Third step be by the tyre shoe pipeline section after bending in the axial direction symmetry cut away half, get half tyre shoe pipeline section near the tyre shoe pipeline section center of circle as tyre shoe, the cross section semicircular in shape groove-like of tyre shoe; 4th step be tyre shoe is fitted in described driving wheel arc groove in and fixed; 5th step to be provided with the cold bending machine driving wheel lathe on the whole of tyre shoe, carries out turnery processing, make the internal diameter of the semi-circular recesses of tyre shoe identical with the external diameter of pipe to be bending to tyre shoe.
This method step is easy, and after this method process, the radius of machining of cold bending machine driving wheel just can adapt to the pipe to be processed of different-diameter, can carry out bending process in arc groove bend pipe to be bending being fit into tyre shoe.Owing to using the present invention can reduce the quantity making driving wheel, therefore, it is possible to reduce costs, increase work efficiency.
The present invention also aims to provide a kind of cold bending machine driving wheel.
For achieving the above object, the invention provides a kind of cold bending machine driving wheel, its periphery is curved groove-like circumferentially, overall curved tyre shoe 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, and the cross section semicircular in shape groove of tyre shoe, 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 be spirally connected or weld.
The present invention can reduce the quantity making driving wheel by the mode installing tyre shoe additional, thus reduces costs, and saves the time making driving wheel, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the enlarged drawing at A place in Fig. 1.
Detailed description of the invention
As depicted in figs. 1 and 2, cold bending machine driving wheel reducing processing method of the present invention is carried out successively according to the following steps:
First step chooses 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 chosen is bent into the tyre shoe pipeline section being not less than 180 degree in forming mill; The concrete angle that bends can be adjusted according to the angle intending bending bend pipe, when the angle intending bending bend pipe is larger, corresponding increase tyre shoe pipe bend angle, the central angle of the tyre shoe pipeline section produced is greater than intend the central angle bending bend pipe.
Third step be by the tyre shoe pipeline section after bending in the axial direction symmetry cut away half, get half tyre shoe pipeline section near the tyre shoe pipeline section center of circle as tyre shoe 3, the cross section semicircular in shape groove-like of tyre shoe 3.
4th step be tyre shoe 3 is fitted in described driving wheel 1 arc groove 2 in and to be spirally connected or the mode of spot welding is fixed; To be spirally connected or the mode of spot welding is easy-to-dismount connected mode, to facilitate the tyre shoe 3 changing different size when processing the bend pipe of different-diameter.
5th step to be provided with cold bending machine driving wheel 1 lathe on the whole of tyre shoe 3, carries out turnery processing, make the internal diameter of the semi-circular recesses 4 of tyre shoe 3 identical with the external diameter of pipe to be bending to tyre shoe 3.
As depicted in figs. 1 and 2, periphery on cold bending machine driving wheel 1 of the present invention circumferentially curved groove-like, overall curved tyre shoe 3 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 be spirally connected or weld.
Need to bend different-diameter, same flexure radius pipe time, the different driving wheel of pipe diameter 1 need not be made, only need the tyre shoe 3 be made into according to method in the present embodiment to be loaded 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 carry out bending work.
Above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: still can modify to the present invention or equivalent replacement, 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 right of the present invention.
