[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] In order to solve the technical problem that leveling a pressure block is time-consuming and labor-intensive, the utility model provides a pipe bending clamp that can save time and labor.

[0023] It should be noted that the pipe bending clamp described in the present invention is used for but not limited to bending pipes, etc. For the convenience of explanation, in the present invention, only a pipe bending clamp applied to bending pipes is used as an example for explanation. The principle of applying a pipe bending clamp to other types of equipment is essentially the same as the principle applied to bending pipes, so they will not be repeated here.

[0024] See also Figure 1 - Figure 3 ,in Figure 1 This is a structural schematic diagram of a pipe bending clamp in an embodiment of the present invention, a pipe bending clamp includes a mounting plate 1, a first clamp 2 and a second clamp 3, the first clamp 2 is installed on one side of the mounting plate 1, the first clamp 2 includes a main clamping block 21 and a secondary clamping block 22 arranged opposite to each other, and the main clamping block 21 is hinged to one end of the secondary clamping block 22; and the second clamp 3 is installed below the first clamp 2, the second clamp 3 includes a U-shaped block 31, a pair of pressure blocks 32 and a pair of first screws 33, the two pressure blocks 32 are oppositely arranged at the top end of the U-shaped block 31, the pressure block 32 is provided with a sliding hole 321, the first screw 33 passes through the sliding hole 321 and is threadedly connected to the U-shaped block 31.

[0025] In this embodiment, by setting the main clamping block 21 and the auxiliary clamping block 22, the staff only needs to rotate the auxiliary clamping block 22 and clamp it on the main clamping block 21 to fix one end of the bent pipe, and then by setting the U-shaped block 31 and the pressure block 32, the other end of the bent pipe can be placed on the inner wall of the U-shaped block 31, and by rotating the two first screws 33 to press the two pressure blocks 32 downward, the other end of the bent pipe can be fixed. Therefore, in the process of fixing the bent pipe, the device does not need to level the pressure blocks 32 at both ends of the bent pipe, saving time and effort.

[0026] In one embodiment, see Figure 1 - Figure 3 The second fixture 3 further includes a U-shaped cylinder 34, both ends of which are fixedly connected to the mounting plate 1 and the U-shaped block 31, and the mounting plate 1, the U-shaped cylinder 34 and the U-shaped block 31 are coaxially arranged.

[0027] In this embodiment, the function of the U-shaped tube 34 is to extend the length of the U-shaped block 31 so that the U-shaped block 31 can support the lower end of the elbow.

[0028] In one embodiment, see Figure 1 - Figure 3 A pair of grooves 311 are formed at the top of the U-shaped block 31 . The two grooves 311 are arranged opposite to each other, and the pressing block 32 is adapted to the grooves 311 .

[0029] In this embodiment, the groove 311 is in an inverted trapezoidal shape, so that the pressure block 32 is adapted to the groove 311. The inner wall of the groove 311 will limit the rotation of the pressure block 32, so that when the first screw 33 is rotated and tightened, it will not drive the pressure block 32 to rotate, so that the pressure block 32 is always in a preset state.

[0030] In one embodiment, see Figure 1 - Figure 3 The groove 311 defines a first threaded hole 312 , and the first screw 33 is threadedly connected to the first threaded hole 312 .

[0031] In this embodiment, the first screw 33 passes downward through the sliding hole 321 and is threadedly connected to the first threaded hole 312, so that the pressure block 32 is slidably sleeved outside the first screw 33, thereby allowing the staff to control the clamping force of the pressure block 32 on the bent pipe by rotating the first screw 33.

[0032] In one embodiment, see Figure 1 - Figure 3 A second threaded hole 313 is formed at the bottom end of the U-shaped block 31 , and a second screw 35 is threadedly connected to the second threaded hole 313 .

[0033] In this embodiment, the opposite end surfaces of the two pressing blocks 32 cooperate with the top end of the second screw 35 to fix the lower end of the elbow.

[0034] Furthermore, the top end of the second screw 35 is wrapped with a buffer pad to prevent the second screw 35 from directly abutting against the bent pipe and causing pressure damage to the surface of the bent pipe.

[0035] In one embodiment, see Figure 1 - Figure 3 A clamping rod 23 is provided between the main clamping block 21 and the auxiliary clamping block 22. One end of the clamping rod 23 is hinged to the end of the main clamping block 21. A clamping groove 221 is provided at the end of the auxiliary clamping block 22. The other end of the clamping rod 23 is used to be clamped in the clamping groove 221.

[0036] In this embodiment, an external thread is provided on the end of the clamping rod 23 away from the main clamping block 21, and a nut and an anti-slip gasket are provided on the external thread. When the end of the clamping rod 23 is clamped in the clamping groove 221, the nut is tightened to complete the fixation of the higher end of the bent pipe.

[0037] In one embodiment, see Figure 1 - Figure 3 The opposing surfaces of the main clamping block 21 and the auxiliary clamping block 22 are both in a concave state.

[0038] In this embodiment, the concave structure of the clamping surface enables the main clamping block 21 and the auxiliary clamping block 22 to better adapt to the curved surface of the bent pipe, thereby improving the stability of the bent pipe.

[0039] In one embodiment, see Figure 1 - Figure 3 , the opposing surfaces of the two pressing blocks 32 are both in an inclined state.

[0040] In this embodiment, the opposite end surfaces of the two pressing blocks 32 are used to press down the bent pipe, thereby achieving fixation of the bent pipe.

[0041] In one embodiment, see Figure 1 - Figure 3 The first clamp 2 further includes a protective cover 24, the inner wall of which is adapted to either end of the elbow.

[0042] In this embodiment, the function of the protective cover 24 is to prevent the first clamp 2 from directly acting on the end of the bent pipe and causing crushing to the end of the bent pipe. Both ends of the bent pipe have external threads, and the inner wall of the protective cover 24 has internal threads that match the external threads, so that the protective cover 24 can better protect the end of the bent pipe.

[0043] Furthermore, in order to adapt to the clamping force of the first clamp 2 , one side of the protective cover 24 is in an open state.

[0044] In one embodiment, see Figure 1 - Figure 3 A gravity block 4 is installed below the second clamp 3 , and the gravity block 4 is arranged opposite to the first clamp 2 .

[0045] In this embodiment, the function of the gravity block 4 is to balance the weight of the first clamp 2 so that the mounting plate 1 can be more stable.

[0046] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0047] First, use the mounting plate 1 to fix the device to the machine tool, and at the same time, install the tool on the machine tool; then, install the protective cover 24 to the end of the bent pipe that does not need to be processed; then, install the protective cover 24 between the main clamping block 21 and the auxiliary clamping block 22, and clamp the clamping rod 23 into the clamping groove 221 to fix one end of the bent pipe; secondly, place the other end of the bent pipe to be processed on the U-shaped block 31, and by tightening the two first screws 33 and the second screw 35, the two pressing blocks 32 cooperate with the top of the second screw 35 to clamp the other end of the bent pipe to be processed; finally, feed the tool to process the end of the bent pipe to be processed.

[0048] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
