[0037] like Figure 5 、 Figure 6 and Figure 8As shown, the bending structure 3 includes two pairs of arms 31, a supporting plate 32, a pair of shafts 33, a pair of first gears 34, a second gear 35, a second electric slide 36, a rack 37 and a pair of force units 38; one end of the two pairs of arms 31 are symmetrically arranged at the left and right ends of the processing table 11 and are located at the four corners, the other end of the arm 31 is located above the processing table 11, the supporting plate 32 is fixedly arranged between the other ends of the arm 31, and the supporting plate 32 is horizontally located above the processing table 11, one end of a pair of shafts 33 are movable through the middle of the supporting plate 32 and are symmetrical to each other, a pair of first gears 34 are fixedly mounted on the top of the shafts 33 and the first gears 34 are relatively engaged, and the second gear 35 is fixedly mounted on one of the shafts 33 and is located below one of the first gears 34 The second electric slide 36 is fixedly provided on the supporting plate 32 and is located in front of the first gear 34.

A pair of force units 38 are respectively fixedly provided on the bottom end of the shaft 33 and are symmetrical to each other; the supporting plate 32 is supported by the support arm 31 and has a certain height above the processing table 11. The rack 37 is driven to move left and right by the second electric slide 36, and one of the shafts 33 is driven to rotate by means of the engagement of the rack 37 and the second gear 35. Since the first gears 34 on the two shafts 33 are relatively engaged, the two shafts 33 are rotated in opposite directions, that is, the force is driven unidirectionally and can be flipped in two directions for synchronous use or used separately.

[0038] like Figure 6 As shown, the force unit 38 includes a support plate 381, a pair of hydraulic cylinders 382, ​​a third electric slide 383, three power rods 384 and a force roller 385; one end of the support plate 381 is fixedly mounted on the bottom end of the shaft 33, and the support plate 381 is parallel to the processing table 11, one end of a pair of hydraulic cylinders 382 is fixedly set on the lower wall of the support plate 381 and is symmetrical near the left and right ends, the third electric slide 383 is fixedly set on the telescopic end of a pair of first hydraulic cylinders 382, ​​the third electric slide 383 is located below the support plate 381, and one end of the three power rods 384 is equidistantly set A third electric slide rail 383 is provided on the upper wall, and the other end of the power rod 384 is movable through the support plate 381.

Since the force roller 385 contacts the pipe to apply force, damage to the hydraulic cylinder 382 is prevented, and the force on the hydraulic cylinder 382 is reduced by the three power rods 384.

[0039] As a preferred solution, the insert arm 16 is movably inserted into the installation groove of the socket 143, and the insert arm 16 is fixed by a tightening bolt 144, which is used to facilitate installation and replacement according to design requirements.

[0040] As a preferred solution, the retaining seat 15 can be cylindrical or fan-shaped with different diameters, and its side walls are arc-shaped walls with different diameters, which are used for different bending angles and radians to meet different processing requirements.

[0041] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0042] Step 1: Support the processing table 11 in the limiting structure 1 horizontally through the supporting legs 12. After the equipment is powered on, loosen the tightening bolts 144 according to the diameter of the processed pipe to move the insert arm 16 to slide in the socket 143, adjust the relative spacing of the stopper 15, and adjust the distance between the stopper 15 and the pad 13 to adjust the corresponding width;

[0043] Step 2: According to processing requirements, the first electric slide rail 141 in the adjustment unit 14 can be driven to drive the two movable frames 142 to move relative to or toward each other, that is, the movable frame 142 passes through the processing table 11 to drive the stopper 15 on the socket 143 to adjust the spacing, that is, change the corresponding force point;

[0044] Step 3: Place one end of the pipe between the stoppers 15 above the four sockets 143, and keep the lower wall of the pipe level by the support platform 13 and the conveying rollers 23 in the conveying structure 2;

[0045] Step 4: The motor 24 on the conveyor frame 21 is driven by the relative series connection of the pulley 25 and the belt 26 to drive the conveying rollers 23 on the roller frame 22 to rotate in the same direction, and the pipe is moved to the right for conveying, or the conveying structure 2 is disassembled to manually feed the pipe;

[0046] Step 5: According to the processing requirements of the pipe:

[0047] (1): For example Figure 9As shown, the pipe is bent into an L shape, and the stopper 15 located at the front right end of the processing table 11 is replaced with a corresponding diameter arc wall. After the pipe is put in, the hydraulic cylinder 382 in one of the force-applying units 38 is driven to extend, and the third electric slide 383 and the corresponding force-applying roller 385 are lowered with the help of the power-assisting rod 384, and the force-applying roller 385 is located at the rear right end of the pipe. Then, the third electric slide 383 is driven to drive the force-applying roller 385 to move left and right to adjust the force-applying position, and the support arm 31 is supported on the high load-bearing plate 32. A second electric slide 36 is provided. By driving the second electric slide 36, the rack 37 moves to the right. The rack 37 engages with the second gear 35 for transmission, and the first gears 34 on the two shafts 33 engage with each other, so that the two shafts 33 can be simultaneously driven to flip in the opposite direction, that is, the two force-applying units 38 can be driven to flip in the opposite direction; the corresponding force-applying units 38 can be driven to flip forward, that is, the force-applying roller 385 moves from the rear side to the front side of the pipe to apply force, and the pipe groove can be flipped around the arc of the block seat 15 through the limit of the block seat 15.

[0048] (2): For example Figure 10 As shown, the pipe is bent into a concave shape, which can be blocked simultaneously by the blocks 15 located at the left and right ends of the front side of the pipe. Then, the force rollers 385 in the two sets of force-applying units 38 are driven to descend and are located at the rear side of the pipe in the same manner as above. Then, the force-bearing rollers are driven to rotate by the shaft 33 to drive the support plate 381 to flip and rotate, and the force-applying position is controlled by the third electric slide 383, so that the two ends of the pipe are driven to bend forward at the same time by the blocks 15.

[0049] (3): For example Figure 11 As shown, the pipe groove is bent into a Z shape, that is, when the pipe is limited to the center by the four stops 15 on the two movable frames 142, the two force-applying units 38 are driven separately in the same way as above, and the force-applying roller 385 of the force-applying unit 38 on the right side is located at the rear side of the pipe to apply force forward to bend, and the force-applying roller 385 of the force-applying unit 38 on the left side is located at the front side of the pipe to apply force backward to bend, and this can be achieved by separate driving;

[0050] During the bending process, the distance between the two ends of the bend is adjusted by the distance of the stop seat 15, and the curvature of the bend is adjusted by replacing the corresponding diameter stop seat 15; the undriven force unit 38 uses the hydraulic cylinder 382 to raise the force roller 385 above the pipe to prevent collision during driving. The force roller 385 can only be lowered when in use to contact the pipe.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Other modifications or replacements made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
