Pressure push rod is horizontally installed on base, and the external part of the hydraulic push rod is provided with the first mould, and first mould is in semicircle
Cylindricality, semicircular groove is provided with its circular arc side, second mould and the 3rd mould are fixedly installed on base
And be oppositely arranged with the first mould, and second mould and the 3rd mould are located at the first mould both sides, second mould and
3rd mould is the wheel-like structure that there is annular groove cylindrical side surface side, and the pressing plate is fixed on the second mould and the 3rd mould
End, play fixed and guide effect.
The pressing plate is provided with the concave architecture of semicircle, the concave architecture and the first mould close to the side of the first mould
Profile match.
The hydraulic push rod is fixed on base by bearing and support, and the bearing and support are separately positioned on hydraulic thrust
The both ends of bar, and the afterbody of the hydraulic push rod is hinged on bearing, the head of the hydraulic push rod is fixedly installed on support.
First mould is hinged on the external part of hydraulic push rod.
Second mould and the 3rd mould are hinged on the supporting plate, and the supporting plate is L-shape, is fixedly installed on base
On.
The base includes working face and supporting leg, and supporting leg is provided with the angle of downside four of the working face.
The retainer ring for being provided with closing laterally outside of the supporting leg, the retainer ring surround four supporting legs,
For strengthening the structural strength of supporting leg.
The utility model has an advantageous effect in that compared with prior art：Cooling water pipe is being bent in the utility model
When, an oval is formed between the second mould and the 3rd mould, because the first mould is semi-cylindrical, that is, trench bottom is taken turns and is less than
Tube outer diameter is simultaneously relatively deep, and the tube wall of the part is pressurized projection when bending beginning in advance, has prepared necessarily for subsequent stretching
Surplus, subsequent bending make the part be stretched, and this bossing is constantly pulled to basically identical with tube outer diameter.So, no
But reduce being thinned for curved outer rim, decrease flowing of the tube wall to the second mould direction in drawing process, effectively
The appearance for avoiding " D " shape inwall.It so not only ensure that external diameter of the pipe after bending in bent portion is substantially circle,
And the internal diameter of pipe is also essentially close to justify, both reduces being thinned for pipe, added the through ball rate of pipe again, simultaneously because
The uniform wall thickness of tube wall, therefore extend its service life.The groove width of 3rd mould is identical with pipe, and groove depth is less than pipe radius
1mm, corresponding resistance is reduced, pipe is steadily slided in groove.Cooling water pipe, bending radius are bent using the utility model
For 1.67 times of pipe diameter when, the wall thickness reduction of pipe is below 11.16%, and through ball rate reaches 85%, and bending radius is pipe
During 2 times of sub- diameter, through ball rate reaches more than 86%, and reduction is less than 6%.
Brief description of the drawings

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the distribution map of mould in the utility model.
In figure：1 be base, 2 be hydraulic push rod, 3 be the first mould, 4 be the second mould, 5 be the 3rd mould, 6 be pressing plate,
7 it is bearing, 8 be support, 9 be supporting plate, 10 is retainer ring.
Embodiment
As shown in Figure 1 and Figure 2, a kind of device for being used to process blast furnace cooling stave cooling water bend pipe of the utility model, including bottom
Seat 1, hydraulic push rod 2, the first mould 3, the second mould 4, the 3rd mould 5 and pressing plate 6, the hydraulic push rod 2 are horizontally installed on bottom
On seat 1, the external part of the hydraulic push rod 2 is provided with the first mould 3, and first mould 3 is in semi-cylindrical, its circular arc side
On be provided with semicircular groove, the mould 5 of the second mould 4 and the 3rd be fixedly installed on base 1 and with the first mould 3
It is oppositely arranged, and the mould 5 of second mould 4 and the 3rd is located at the both sides of the first mould 3, the mould 5 of the second mould 4 and the 3rd
It is the wheel-like structure that there is annular groove cylindrical side surface side, the pressing plate 6 is fixed on the second mould 4 and the upper end of the 3rd mould 5, rises
Fixed and guide effect.
The pressing plate 6 is provided with the concave architecture of semicircle, the concave architecture and the first mould close to the side of the first mould 3
The profile of tool 3 matches.
The hydraulic push rod 2 is fixed on base 1 by bearing 7 and support 8, and the bearing 7 and support 8 are separately positioned on
The both ends of hydraulic push rod 2, and the afterbody of the hydraulic push rod 2 is hinged on bearing 7, the head of the hydraulic push rod 2, which is fixed, to be set
