Fig. 2 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment one.
As shown in Figure 1, 2.
With straight section spatially spiral coil pipe push away an o ing method, it comprises the following steps:
First, clamp mechanism 1 is utilized to be clamped on bending machine by needing the afterbody of the straight tube 2 pushing away o ing, the other end of straight tube 2 is placed in two directive wheels 3,4, a centre wheel 9 and one to push away between curved steamboat 5 and clamp, wherein two directive wheels and pinch wheels are positioned at the outside in straight tube helical buckling direction to be formed, and centre wheel is positioned at opposite side; Select the triangle skewback 7 that can be elevated at identical oblique angle to be placed on straight tube according to the lead angle of spiral coil simultaneously and intend bending bottom, one end; Triangle skewback can adopt screw pair to be elevated.As shown in Figure 1;
Secondly, move according to the radius of final forming spiral and push away the angle of curved steamboat 5 to setting, straight tube end directive wheel, push away curved steamboat and centre wheel common constraint under be partially formed arc section 8;
3rd, manipulation main shaft of pipe bender horizontal feed, straight tube is travelled forward in the horizontal direction, and bending machine clamp mechanism synchronously travels forward along with straight tube, straight tube directive wheel, push away curved steamboat and centre wheel and triangle skewback acting in conjunction under obtain required spiral coil.
Details are as follows:
1. be placed on bending machine by pipe, manipulation bending machine, makes bending machine clamp mechanism 1 step up pipe afterbody, and be then that directive wheel 3,4 clamping puts in place, push away curved steamboat 5 and arrive position, at this moment tube bank is straight tube.
2. manipulate bending machine, make to push away the central rotation of curved steamboat 5 around centre wheel 7 under bend pipe pattern, stop after turning over certain angle (bend pipe pre-sets rotational angle, calculates or adopt software to calculate by Conventional mathematical) in-position 6.
3. select the triangle skewback at identical oblique angle with it according to pushing away curved spiral coil lead angle β (screw pair structure is arranged at skewback bottom, adjustablely to move up and down) be positioned over below tube end, the screw mechanism of adjusting triangle skewback bottom, makes tube end produce lift angle β.
4. manipulate main shaft of pipe bender horizontal feed, pipe is travelled forward in the horizontal direction, bending machine clamp mechanism also synchronously travels forward along with pipe, pipe is formed spiral-shaped under the acting in conjunction being positioned at wheel 4,6,9, simultaneously due to the effect of triangle skewback 7, simultaneously spiral coil produces lift angle β, thus push away curved go out requisite space spiral coil.
It is to be noted that the outside circle that the radius of spin R(that can derive shaping spiral coil in theory by Fig. 2 spiral coil screw diameter shaping mathematical derivation schematic diagram pushes away the spiral coil of roll forming is and takes turns the simultaneously tangent circles of 4,6,10 3 circles, the radius of circle value obtained deducts the radius of spin value that namely tube outer diameter radius value obtains spiral coil) with push away the mathematical relationship of curved steamboat at 5 to 6 place rotational angle α.Or in the softwares such as Proe, draw corner α according to the required radius of spin by software automatic analysis by " feasibility analysis ".Corner α mentioned here is not considering that pipe obtains ideal value (sudden change in fact here can cause screw diameter bigger than normal a little) under the catastrophe of wheel 4 upper contact, so consider, the corner α that the corner arranged in practical operation should obtain than software analysis is bigger than normal.
Embodiment two.
As shown in Figure 1.
A kind of spatially spiral coil pipe with straight section push away o ing mechanism, it comprises the first directive wheel 3, second directive wheel 6, centre wheel 9, pushes away curved steamboat 5 and triangle skewback 7, one end of straight tube 2 is clamped in the clamp mechanism 1 of bending machine, centre wheel 9 is positioned at the inner side of the helix after straight tube 2 shaping, first directive wheel 3, second directive wheel 6, push away curved steamboat 5 and triangle skewback 7 be positioned at straight tube 2 be shaped after the outside of helix, wherein triangle skewback 7 is positioned at the distalmost end place of straight tube 2 relative to clamp mechanism 1; First directive wheel 3, second directive wheel 6, centre wheel 9 and clamp mechanism 1 make straight tube 2 straight line locate, push away curved steamboat 5 and (prior art self design in addition can be adopted at driving mechanism, also can utilize lathe X, Y-direction feed mechanism realized) drive lower do along straight tube axially and radial movement make straight tube end form arc section 8, the diameter of this arc section and the diameter compatible of final forming spiral coil pipe; Triangle skewback 7 makes straight tube end form lead angle that is fixing or change under elevating mechanism (screw pair structure) drives; Bending machine drives clamp mechanism 1 to promote straight tube and move axially along straight tube, move in advance desired location 6 place push away the effect of curved steamboat 5 and triangle skewback under obtain the spiral coil of required diameter and lift angle.
