[0022] like Figure 1The utility model discloses a simple metal pipe bending device, including bending base 1, the upper side middle part of bending base 1 is fixed with operating lever 2, the downside of bending base 1 is set to the slot structure of the opening downward, and the shape of slot structure is set to the arc shape of the downward concave, is fixed with fixed sleeve pipe 3 at one end of slot structure, makes the port of fixed sleeve pipe 3 and the slot port of slot structure alignment.
[0023] As Figure 6 As shown in use, the metal pipe to be bent one end is inserted into fixed sleeve pipe 3, then easily presses down operating lever 2, makes metal pipe bending part gradually fall into the slot of slot structure, can complete the accurate bending operation of metal pipe. Successfully break through the limitation of traditional bending machine, and its structure design is simple and compact, and easy to operate, and easy to carry and deploy, completely get rid of the restriction of construction environment and site. It can realize flexible and efficient bending of metal pipe directly on site, completely eliminates the cumbersome process of pipe carrying, effectively avoids the possible safety hazard in the carrying process. Not only ensure the safety of the operation process, also greatly simplify the operation process, thereby significantly improve the work efficiency. Realize the quick and accurate bending of metal pipe, perfect fit the double pursuit of higher efficiency and safety of construction
[0024] As Figures 1-4As shown, in an embodiment of the present application, the specific setting mode of the bending base 1 is provided, the bending base 1 comprises a first curved plate 11 and a second curved plate 12, the first curved plate 11 and the second curved plate 12 are same in shape and size, and the first curved plate 11 and the second curved plate 12 are oppositely arranged at intervals. A plurality of back braces 13 are fixed between the first curved plate 11 and the second curved plate 12, the plurality of back braces 13 are arranged at intervals in a circular arc on the upper half of the first curved plate 11 and the second curved plate 12, so that the first curved plate 11, the second curved plate 12 and the plurality of back braces 13 form a groove-shaped structure. The operating rod 2 is fixed on the back brace 13 located in the middle of the first curved plate 11 and the second curved plate 12, and the fixed sleeve 3 is fixed between the first curved plate 11 and the second curved plate 12. The first curved plate 11 and the second curved plate 12 act as two side edges of the groove-shaped structure, and the plurality of back braces 13 act as the groove bottom of the groove-shaped structure. When the metal pipe is bent, the first curved plate 11 and the second curved plate 12 can limit the bending part of the metal pipe, and the plurality of back braces 13 can limit the bending shape of the metal pipe. The operating rod 2 and the first curved plate 11 and the second curved plate 12 form an inverted T-shaped structure, so that it is more convenient to use during the pressing process. The two sides of the fixed sleeve 3 are limited and fixed by the first curved plate 11 and the second curved plate 12, which can ensure the connection firmness of the fixed sleeve 3 and improve the service life of the device. In order to ensure the bending shape of the metal pipe, the back brace 13 is arranged as an arc-shaped plate, and the arc-shaped plate is coaxially arranged with the first curved plate 11 or the second curved plate 12. In this way, the bending curvature of the metal pipe, the arc-shaped plate, the first curved plate 11 and the second curved plate 12 is consistent during the bending process, so that the bending shape of the metal pipe is consistent.
[0025] As Figures 1-2As shown, in one embodiment of the present invention, a first support rod 21 and a second support rod 22 are provided on the outer peripheral wall of the operating rod 2, and the first support rod 21 and the second support rod 22 are symmetrically arranged. One end of the first support rod 21 is fixedly connected to the upper half of the outer peripheral wall of the operating rod 2, and the other end of the first support rod 21 is fixedly connected to the back rib 13 fixed at one end of the first curved plate 11 and the second curved plate 12. One end of the second support rod 22 is fixedly connected to the upper half of the outer peripheral wall of the operating rod 2, and the other end of the second support rod 22 is fixedly connected to the back rib 13 fixed at the other end of the first curved plate 11 and the second curved plate 12. During the bending process of the metal tube, the first support rod 21 shares the tension of the operating rod 2, and the second support rod 22 shares the pressure of the operating rod 2, thereby ensuring the stability of the connection of the operating rod 2. To facilitate the bending operation, a first operating handle 23 and a second operating handle 24 are fixed to the upper half of the operating rod 2, with the first operating handle 23 positioned above the first support rod 21 and the second operating handle 24 positioned above the second support rod 22. The first operating handle 23 faces the fixed sleeve 3, and the second operating handle 24 faces the opposite direction of the first operating handle 23, so that the first operating handle 23, the second operating handle 24, and the operating rod 2 form a cross-shaped structure. During the metal tube bending process, the operator can hold the first operating handle 23 tightly and pull it back with one hand while holding the second operating handle 24 tightly and pressing it downward with the other hand, making the operation smoother and more labor-saving.
[0026] like Figure 2 Combined with Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the axis of the fixed sleeve 3 coincides with or is parallel to the tangent line of the centerline of the trough structure. This means that the vertical position of the fixed sleeve 3 can be adaptively changed based on the width of the first curved plate 11 or the second curved plate 12 in the trough structure. However, the axis of the fixed sleeve 3 must remain tangent to or parallel to the tangent line of the curved centerline of the trough structure. This ensures that the curvature of the metal pipe at the starting point of the bend is consistent with the curvature of the subsequent curved portion, preventing abrupt corners in the curved portion of the metal pipe.
[0027] In order to prevent the metal pipe from falling off in the bending process, and adapt to the metal pipe of different pipe diameter, the locking assembly 31 is arranged on the outer peripheral wall of the fixed sleeve 3. The locking assembly 31 comprises a locking block 311 and an adjusting handle 312, the locking block 311 is welded on the outer peripheral wall of the fixed sleeve 3, the central part of the locking block 311 is provided with a threaded hole communicated with the inner peripheral wall of the fixed sleeve 3, the adjusting handle 312 is screwed in the threaded hole of the locking block 311, the metal pipe inserted into the fixed sleeve 3 is fixed through the adjusting handle 312, so as to prevent the metal pipe from rolling or slipping off, and facilitate the subsequent bending operation. More specifically, in order to facilitate the rotation of the adjusting handle 312, the adjusting handle 312 comprises a threaded rod 3121 and an adjusting rod 313, the lower half of the threaded rod 3121 is provided with a threaded part matched with the threaded hole of the locking block 311, the upper half of the threaded rod 3121 is provided with a ball head 3122, the ball head 3122 is provided with a mounting hole, the axis of the mounting hole is perpendicular to the axis of the threaded rod 3121, and the middle part of the adjusting rod 313 is fixed in the mounting hole of the ball head 3122 in an interference fit manner, so that when the adjusting handle 312 is rotated, the length of the threaded rod 3121 is adjusted by rotating the adjusting rod 313, and the metal pipe of different pipe diameter is fixed more conveniently.
[0028] In order to further prevent the metal pipe from rolling or slipping off, the anti-skid rubber pad 32 is bonded to the inner peripheral wall of the fixed sleeve 3, the anti-skid rubber pad 32 accounts for at least 1 / 3 of the surface area of the inner peripheral wall of the fixed sleeve 3, when the threaded rod 3121 tightly pushes the metal pipe, the metal pipe is closely connected with the anti-skid rubber pad 32, and the circumferential and axial displacement of the metal pipe is limited through the anti-skid rubber pad 32.
