Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in Fig. 1 (a), present invention specific implementation includes the identical basic unit of multiple structures being sleeved on tubing
Body, each basic unit body are mainly made of matrix 1, retention bead 2 and electromagnet 3, and it is half-and-half two-part two that matrix 1, which is divided to,
A sub- matrix is in spindle after the docking of two subbase bodies, so that two subbase bodies are being circular arc towards the both side surface along tubing axial direction
Face, each subbase body are in half of spindle, and 1 set of matrix outside tubing, is square, along tubing along the matrix 1 that tubing is axially looked
The matrix 1 that radial side is looked is in spindle, equal part spindle of the shape from circle.Matrix 1 has the appearance of arc-shaped
Spindle is done by justifying Along ent and is obtained in face.
As shown in Fig. 1 (b) and Fig. 2, two subbase bodies are joined between the side of docking contact face by Hinge mechanism 5,
Two subbase bodies are fastened and fixed between the other side of docking contact face by lock-screw 6, the outer middle side part tool of two sub- matrixes
There is Hinge mechanism 5, upper and lower two subbases body carries out rotating folding by Hinge mechanism, and by lock-screw 6 in upper and lower two subbase
Body is locked after closing.Two subbase bodies offer semi-circular hole, semi-circular hole pair in the middle of contact face
Connect the through-hole for constituting and passing through installation for tubing.Tubing by rubber axle sleeve 4 be clamped suit in through-holes, rubber axle sleeve 4 by
Two semicircular ring axle sleeves are constituted, and are tightly attached to two semi-circular hole inner walls respectively.
As shown in Figure 3 and Figure 4, two subbase bodies are provided with one group of electromagnet 3 in internal two sides, and electromagnet 3 is embedded
It being fitted into subbase body, the pole polarity direction of electromagnet 3 shows the pole N or the pole S in the outer surface of subbase body along tubing axial direction,
External control circuit is arranged by the pole polarity that radio wave controls electromagnet 3, changes the polarity of subbase external surface, into
And it realizes attracting each other between neighboring unit cells body or repels, and then crooked pressure is applied to tubing and is bent to
Shape.
Two subbase bodies adjacent base 1 when the surface of two lateral edge tubing axial directions is provided with for bend pipe is contacted and is prevented
The retention bead 2 that extreme position blocks.In specific implementation, retention bead 2 uses stop screw, and the thread segment of stop screw revolves
Enter to be attached to sub- intrinsic silicon, the nut segment of stop screw is exposed at sub- matrix surface.
As shown in Figure 3 and Figure 4, how curved the present invention is as follows for the diameter segmentation bending forming process of ultra-thin-wall tubing:
By changing the magnetic pole of electromagnet, being close to for multiple cell cubes is realized, the side of the power suffered by the upper and lower two subbases body
To it is different when, rotary motion can be generated.
And since some receives attraction, it is tight that each basic unit body of progress bending machining has one end
It sticks together.Due to basic unit body geometric shape, the maximum rotation angle between every two basic unit body is solid
Fixed, therefore the bending machining that certain angle is carried out to tubing may be implemented, and curved active force is distributed across tubing
Multiple positions.The specific implementation is as follows:
1, tubing will be processed and is packed into the hole that two subbase body semi-circular through hole are constituted up and down, and fix to clamp tubing.
2, the magnetic pole of electromagnet is set, the electromagnet pole side of all basic unit external surfaces is set as the pole N, separately
Side is set as the pole S.If left side is set as the pole N, right side is set as the pole S.Equipment basic unit body is received due to upper and lower subbase body at this time
Attraction, all devices basic unit body are close to each other.
3, the magnetic pole of side is constant, and two subbase body a part therein, magnetic pole change other side magnetic pole up and down.For example, single
The magnetic pole of first body left outer surface is constant, and the magnetic pole of right side lower half portion outer surface is changed into the pole N by the pole S.At this point, tables of equipment
It attracts each other between subbase body on first body, mutually exclusive between lower subbase body, equipment starts to revolve by axis of the vertex of suction side
Turn, when going to extreme position, by limit convex card lifting master, rotation terminates.
4, it while equipment is rotated, drives the part of folded tubing to be rotated, completes Tube Bending Deformation
Process.
Specific example procedure of processing is as follows:
The number of curved angle adjustment processing cell cube used, every two equipment can realize certain bending as needed
The processing of angle, and two parts up and down of all equipment used are opened, it is semicircle that processing tubing is packed into two parts up and down
Simultaneously locking unit body is closed in the hole that through-hole is constituted, and processes tubing so as to fixed.
Bending preparation is carried out, the magnetic pole of electromagnet is set, a side external surface of all devices cell cube is set as the pole N, separately
One side external surface is set as the pole S.All left sides are such as set as the pole N, right side is set as the pole S.Unit body is due to upper and lower position at this time
Attraction is received, all devices cell cube is close to each other, as shown in Figure 3.
Bending machining is carried out, according to the direction of required bending pipes, the magnetic pole for adjusting equipment side is constant, on the other side
A part in lower two parts magnetic pole changes.For example, being bent if you need to tubing to upper right side, the magnetic pole on the left of equipment is constant,
The magnetic pole of right side lower half portion is changed into the pole N by the pole S.At this point, unit body top half is attracted each other, lower half portion is mutual
Mutually repel, equipment starts to rotate by axis of the vertex of suction side, when going to extreme position, is blocked by retention bead, such as Fig. 4
It is shown.
While cell cube is rotated, cell cube drives the part of folded tubing to be rotated, and completes tubing segmentation
The process of bending deformation.Electromagnet is then closed, lock-screw is opened, removes process equipment.
Thus implement to pass through multiple processing cell cubes pair as it can be seen that apparatus of the present invention can be realized in Pipe Bend Forming
Tubing carries out segmentation bending, so that distribution of forces is more uniform compared to traditional pipe bending mechanism, improves bending pipes processing
Quality, be suitable for the processing of ultra-thin-wall tubing.Apparatus of the present invention use fabricated structure, especially suitable in erecting yard
Carry out bend pipe operation.The cross-sectional shape of matrix can increase and decrease the number of component from the equal part spindle of circle as needed, with
Change the angle of bending pipes.Furthermore change processing plane, each group cell cube is in antarafacial position as required, can filled
The space arbitrary curve bending machining of tubing is realized with scene.
