In do not occur string pipe.
As a kind of perferred technical scheme, the carcass includes left carcass and right carcass, and the top shoe includes connection
Sliding block and and the sliding slider arranged on the connection sliding block bottom, the left carcass and the right carcass be respectively arranged on the connection
The both sides of sliding block.
As a kind of perferred technical scheme, the sliding block is equipped with sliding slot, and the top shoe slides and is arranged on the cunning
In groove.
As a kind of perferred technical scheme, the sliding block is equipped with the limiting device that the spacing top shoe slides.
As a kind of perferred technical scheme, sliding axle is equipped with the center of the contact roller, the sliding axle is connected with
Drive the driving device of the sliding axle horizontal direction movement.
The beneficial effects of the utility model are shown：
The utility model drives sliding block, top shoe and carcass to rotate by tumbler, in contact roller and carcass one
Under the collective effect of the spiral groove of side, it is possible to achieve small-bend radius bent pipe, after the bend pipe for completing side, passes through sliding in slip
Block, the spiral groove of the opposite side of carcass is corresponding with contact roller, it is possible to achieve the bend pipe of the opposite side of carcass, so as to fulfill small
Bending for the minor diameter helix tube of the continuous helical ascending manner structure of bending radius, it is easy to operate, avoid the nothing of conventional bend pipe
The problem of method positions or positioning is inconvenient, saves manufacturing cost, improves work efficiency.

Embodiment
In order to facilitate the understanding of those skilled in the art, the utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the overall structure diagram of the utility model, including carcass, carcass both sides are equipped with spiral groove 4, spiral shell
Spiral groove 4 spiral of the coil 1 along carcass both sides, carcass are fixedly connected with top shoe, top shoe basal sliding connection
There is sliding block 6, sliding block 6 is connected with tumbler (not shown), and carcass side is equipped with contact roller 9, and carcass sidepiece is equipped with
Pressing plate 7；Carcass includes left carcass 10 and right carcass 3, and top shoe includes connection sliding block 2 and and the cunning arranged on 2 bottom of connection sliding block
Movable slider 5, left carcass 10 and right carcass 3 are respectively arranged on the both sides of connection sliding block 2；Sliding axle 8 is equipped with the center of contact roller 9.
The specific working mode of the utility model is as follows：
As shown in Figure 1, one end of helix tube 1 to be fixed on to the sidepiece of carcass by pressing plate 7, and by the tube body of helix tube 1
It is positioned in the spiral groove 4 of carcass side, while contact roller 9 is compressed to the pipe bent position for the treatment of of helix tube 1, starts tumbler
Sliding block 6, top shoe and carcass is driven to rotate, so that spiral groove 4 and contact roller 9 of the helix tube 1 on carcass
Under collective effect, helix tube 1 is bent to the opposite side of carcass along spiral groove 4, completes first time bend pipe, unclamps contact roller
9, slide top shoe so that the spiral groove 4 of carcass opposite side is corresponding with contact roller 9, and the tube body of helix tube 1 is positioned over tire
In the spiral groove 4 of the opposite side of body, repeat the above steps, then can complete second of bend pipe, and so on, it is possible to achieve
The helix tube 1 of minor radius spiral formula structure is bent.
Wherein, left carcass 10 and right carcass 3 are connected between connection sliding block 2 using dovetail groove respectively so that when helix tube 1
After the completion of bending, left carcass 10, right carcass 3 and helix tube 1 can be risen at the same time, be allowed to separate with connection sliding block 2, Ran Houzai
