[0030] Embodiment 1

[0031] Please refer to Figure 1 , Figure 4 and Figure 5A bending device for steel pipe processing, the bending device includes an operating platform 1, a limiting assembly 7 and a supporting assembly 3, the limiting assembly 7 is fixedly arranged at one end of the operating platform 1, the limiting assembly 7 includes a limiting block 71 fixed to the side wall of the operating platform 1 and a limiting groove 72 opened above the limiting block 71, the inner side wall of the limiting groove 72 is used to contact with the steel pipe to clamp one end of the steel pipe, and the limiting groove 72 is used to limit the position of one end of the steel pipe. It can be further explained that the bottom end of the limiting groove 72 is set as a semicircular arc groove, because the steel pipe needs to be bent during the bending process. The positions of both ends of the steel pipe are stabilized, so that when an external force is applied to a certain position of the steel pipe, such as the middle position, the middle position of the steel pipe will be squeezed by the force to bend, thereby realizing the bending function. The support component 3 is arranged in the middle position of one side of the operating platform 1. When the diameter of the steel pipe is different, the force to be applied will also be different. The larger the diameter of the steel pipe, the greater the force applied. In order to avoid the problem of collapse of the steel pipe during the bending process, the height of the support component 3 on one side of the operating platform 1 needs to be adjusted. When the inner diameter of the steel pipe is large, The height of the support assembly 3 is adjusted higher. When the inner diameter of the steel pipe is small, the position of the support assembly 3 on one side of the operating platform 1 is adjusted lower to ensure the fit between the steel pipe and the support assembly 3 and prevent the steel pipe from collapsing from the inner side of the support assembly 3 during the bending process. The support assembly 3 penetrates the main body of the operating platform 1 and is movably connected to the side wall of the operating platform 1. The support assembly 3 includes a through column 31 movably arranged on the surface of the operating platform 1, a movable groove 36 opened on one side of the through column 31, a block 32 movably arranged on the inner side of the movable groove 36, and a block 32 rotating on the side wall of the movable groove 36. The spring rod 38 and the tooth bud block 37 connected to the end face of the spring rod 38, the end face of the block 32 and the side wall of the operating platform 1 are movably connected, the side wall of the block 32 and the top wall of the tooth bud block 37 are abutted, the tooth bud block 37 is used to limit the block 32 to slide up and down inside the movable groove 36, the support assembly 3 also includes a horizontal plate 1 33 fixed at the top end of the through column 31, a horizontal plate 2 35 fixed to the top end of the horizontal plate 1 33 and a limiting groove 1 34 opened at the connecting position of the horizontal plate 1 33 and the horizontal plate 2 35, the limiting groove 1 34 is used to limit the position of one end of the steel pipe away from the limiting assembly 7.

[0032] During the use of this embodiment, the height of the support assembly 3 is first adjusted according to the inner diameter of the steel pipe. The block 32 and the side wall of the operating platform 1 are in a mortise and tenon structure, and the end face of the block 32 is clamped with the side wall of the operating platform 1. At this time, it is only necessary to adjust the height of the block 32 at the inner side of the movable groove 36 to drive the through-column 31 to be adjusted up and down as a whole. First, the end face of the tooth bud block 37 is fixedly connected to the spring rod 38, and the spring rod 38 penetrates the side wall of the through-column 31 and is rotatably connected to the side wall of the through-column 31. The spring rod 38 is restrained by the spring on the side wall of the through-column 31 to produce rebound. When the block 32 is located above the tooth bud block 37, the block When the block 32 moves from top to bottom on the inside of the movable groove 36, because the tooth bud block 37 is in the shape of an inverted triangle that is wide at the top and narrow at the bottom, when the side wall of the block 32 contacts the wide surface at the top of the tooth bud block 37, the wide surfaces of the two pairs of tooth bud blocks 37 provide support force for the block 32, and the spring rod 38 will not rebound. When the block 32 slides on the inside of the movable groove 36 and is pushed upward from bottom to top, because the support force of the narrow surface of the tooth bud block 37 at the connection point is less than the support force of the wide surface, the spring rod 38 rebounds and the tooth bud block 37 contracts on the side wall of the through column 31, thereby completing the up and down sliding of the block 32 on the inside of the movable groove 36 and limiting the sliding position of the block 32.

[0033] Embodiment 2

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 The bending device also includes a supporting bottom box 2 fixed at the bottom end of the operating platform 1, a servo motor 4 fixed to the bottom wall of the operating platform 1 on one side of the supporting bottom box 2, a brake assembly 5 fixed at a corresponding position above the servo motor 4, and a pushing assembly 6 movably connected to one end of the brake assembly 5. It can be further explained that the servo motor 4 drives the brake assembly 5 to rotate. Because the brake assembly 5 is connected to the pushing assembly 6, the rotation of the brake assembly 5 drives the pushing assembly 6 to apply thrust to the side wall of the steel pipe to bend the steel pipe.

[0035] The brake assembly 5 includes a tray 51 connected to the output end of the servo motor 4, a rotating disk 52 rotating above the tray 51, a connecting column 53 fixed to the top of the rotating disk 52, a connecting bar 54 fixed to one side of the connecting column 53, a sliding groove 55 opened at the top of the connecting bar 54 and a through hole 1 56 opened on the side wall of the connecting bar 54. The pushing assembly 6 includes a connecting block 61 slidably connected to the inner side of the connecting bar 54, a through hole 2 62 opened on the side wall of the connecting block 61, and a connecting block 61 fixed to the top of the connecting bar 54. The splicing block 64 at one end of the connecting block 61 and the pushing block 65 fixed on the side wall of the splicing block 64, one end of the pushing block 65 contacts and abuts against the outer side of the steel pipe, the pushing component 6 also includes a positioning bar 63 fixed at the bottom end of the connecting block 61, the positioning bar 63 slides inside the sliding groove 55, the positioning bar 63 is used to prevent the connecting block 61 from shaking inside the sliding groove 55, the same bolt is arranged in the through hole 1 56 and the through hole 2 62, and the bolt is used to limit the position of the pushing component 6 on the inner side of the connecting horizontal bar 54.

[0036] During use of this embodiment, first, the connecting block 61 is calibrated with the inner side of the connecting cross bar 54 through the positioning bar 63 at the bottom and slides on the inner side of the connecting cross bar 54. According to the requirements of the bending position of the steel pipe, the combined length of the brake assembly 5 and the pushing assembly 6 can be adjusted, and then the end face of the pushing block 65 is allowed to contact the outer wall of the steel pipe. During the assembly of the brake assembly 5 and the pushing assembly 6, the through hole 1 56 on the outer side of the connecting cross bar 54 and the through hole 2 62 on the outer side of the connecting block 61 are calibrated and aligned. After alignment, the bolts are simultaneously passed through the through hole 2 62 and the through hole 1 56 to define the position of the connecting block 61 on the inner side of the sliding groove 55. The assembly is completed, and then the force applied by the brake assembly 5 drives the pushing block 65 to advance toward the outer wall of the steel pipe to achieve bending.

[0037] Working principle: First, adjust the height of the support assembly 3 according to the inner diameter of the steel pipe. The block 32 and the side wall of the operating platform 1 are in a mortise and tenon structure. The end face of the block 32 is clamped with the side wall of the operating platform 1. At this time, you only need to adjust the height of the block 32 inside the movable groove 36 to drive the through-column 31 to adjust up and down as a whole. First, the end face of the tooth bud block 37 is fixedly connected to the spring rod 38. The spring rod 38 penetrates the side wall of the through-column 31 and is rotatably connected to the side wall of the through-column 31. The spring rod 38 penetrates the side wall of the through-column 31 and is rotatably connected to the side wall of the through-column 31. The side wall of the through column 31 is restrained by the spring to produce rebound. When the block 32 is located above the tooth bud block 37, the block 32 moves from top to bottom inside the movable groove 36. Because the tooth bud block 37 is in the shape of an inverted triangle with a wide top and a narrow bottom, when the side wall of the block 32 contacts the wide surface of the top of the tooth bud block 37, the wide surfaces of the two pairs of tooth bud blocks 37 provide support for the block 32, and the spring rod 38 will not rebound. When the block 32 slides inside the movable groove 36 and is pushed from bottom to top, because the tooth bud block 37 at the joint is 7, the supporting force of the narrow surface is less than that of the wide surface. At this time, the spring rod 38 rebounds, and the tooth bud block 37 contracts on the side wall of the through column 31, thereby completing the up and down sliding of the block 32 inside the movable groove 36 and limiting the sliding position of the block 32, completing the adjustment of the height of the support assembly 3 on one side of the operating platform 1, and the connecting block 61 slides on the inner side of the connecting cross bar 54 through the positioning bar 63 at the bottom end and the inner side of the connecting cross bar 54. According to the requirements of the bending position of the steel pipe, the brake assembly 5 and the push rod 5 can be adjusted. The combined length of the moving component 6 is adjusted, and the end face of the pushing block 65 is allowed to contact the outer wall of the steel pipe. During the assembly process of the brake component 5 and the pushing component 6, the through hole 1 56 on the outside of the connecting cross bar 54 and the through hole 2 62 on the outside of the connecting block 61 are calibrated and aligned. After alignment, the bolts are simultaneously passed through the through hole 2 62 and the through hole 1 56 to limit the position of the connecting block 61 on the inner side of the sliding groove 55. The assembly is completed, and then the force applied by the brake component 5 drives the pushing block 65 to advance toward the outer wall of the steel pipe to achieve bending.
