DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the embodiments of the utility model and the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0027] The utility model embodiment provides a pipe bending cutting integrated machine, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , mainly includes a frame 1, a bending assembly 2, a feeding assembly 3 and a cutting assembly 4.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 In the embodiment of the present application, the pipe bending and cutting integrated machine includes a frame 1, a pipe bending assembly 2, a feeding assembly 3 and a cutting assembly 4. The frame 1 is a basic component, which provides an installation foundation for other components. The pipe bending assembly 2 and the feeding assembly 3 are respectively arranged on different sides of the frame 1, and the cutting assembly 4 is arranged between the pipe bending assembly 2 and the feeding assembly 3. The pipe bending assembly 2, the feeding assembly 3 and the cutting assembly 4 are all fixed on the frame 1. When in use, the feeding assembly 3 can transport the pipe to be processed to the arrangement position of the pipe bending assembly 2. The pipe bending assembly 2 clamps the pipe to be processed and rotates to bend part of the pipe to be processed into a curved pipe. After the processing of the pipe bending assembly 2 is completed, the cutting assembly 4 separates the straight pipe part and the curved pipe part of the pipe to be processed. The subsequent feeding assembly 3 continues to transport the remaining pipe to be processed to the pipe bending assembly 2 for processing. By arranging the pipe bending assembly 2 and the cutting assembly 4 on the frame 1, the steps of cutting and bending the pipe to be processed are performed on the same frame 1, and by providing the feeding assembly 3, the stability of clamping the pipe to be processed is improved, thereby improving the processing efficiency of the pipe to be processed.

[0029] In one embodiment, the pipe bending assembly 2 includes a bending seat 21 and a fixing member 22. The bending seat 21 is fixedly connected to the motor shaft of the driving motor 5. The bending seat 21 and the fixing member 22 are fixedly connected. The bending seat 21 is provided with a bending groove 23. The pipe to be processed is arranged in the bending groove 23. The fixing member 22 has a fastening effect and is used to fix the position of the pipe to be processed in the bending groove 23. The driving motor 5 is started to drive the bending seat 21 to rotate, so as to bend part of the pipe to be processed on the bending seat 21 into a bent pipe.

[0030] Specifically, the bending seat 21 is composed of a first plate, a second plate and an intermediate plate, the first plate and the second plate are arranged on both sides of the intermediate plate, and the cross-sectional areas of the first plate and the second plate are larger than the cross-sectional area of ​​the intermediate plate, and a bending groove 23 is provided in the intermediate plate. When the pipe to be processed is in the bending groove 23, when the bending seat 21 rotates, the pipe to be processed will rotate, and the pipe to be processed is bent during the rotation process. At this time, the first plate and the second plate play a limiting role on the pipe to be processed, thereby improving the stability of the pipe to be processed during the bending process.

[0031] In one embodiment, the fixed seat includes a connecting plate 221 and a first telescopic rod 222, the connecting plate 221 is an L-shaped plate, one end of the connecting plate 221 is integrally connected to the bending seat 21, and the other end of the connecting plate 221 is fixedly connected to the fixed end of the first telescopic rod 222, and a fixing block is provided on the telescopic end of the first telescopic rod 222, and a fixing groove is provided on the fixing block. When the feeding assembly 3 sends the pipe to be processed into the bending groove 23, the first telescopic rod 222 is started, and the first telescopic rod 222 moves toward the direction of the pipe to be processed, so that the inner wall of the bending groove 23 and the inner wall of the fixed groove are both in contact with the pipe to be processed, thereby fixing the position of the pipe to be processed in the bending groove 23 to prevent the pipe to be processed from falling off from the bending groove 23.

[0032] Preferably, in order to save the space occupied by the pipe bending and cutting machine, a mounting groove is provided on the frame 1 , the driving motor 5 is embedded in the mounting groove, and the motor shaft of the driving motor 5 is fixedly connected to the bending seat 21 .

[0033] In one embodiment, the feeding assembly 3 includes a clamping unit 31 and a transport unit 32. The transport unit 32 is arranged on both sides of the clamping unit 31, and the transport unit 32 is fixedly connected to the clamping unit 31. The clamping unit 31 is used to clamp the pipe to be processed. The transport unit 32 drives the clamping unit 31 to move on the frame 1, and then transports the pipe to be processed to the position of the pipe bending assembly 2 for pipe bending operation.

[0034] The clamping unit 31 includes two symmetrically arranged clamping blocks 311 and two second telescopic rods 313. The two clamping blocks 311 are each provided with a first groove 312. The first groove 312 is an arc-shaped groove, which makes it easier for the clamping blocks 311 to grasp the pipe to be processed. The telescopic ends of the two second telescopic rods 313 are respectively fixedly connected to the two clamping blocks 311, and the fixed ends of the two second telescopic rods 313 are connected to the transport unit 32. The two second telescopic rods 313 can drive the two clamping blocks 311 to move toward each other, thereby clamping the pipe to be processed.

[0035] The transport unit 32 includes two sliding grooves 321 arranged in parallel on the frame 1, and sliding blocks 322 arranged inside the two sliding grooves 321. The two sliding blocks 322 are respectively fixedly connected to the fixed ends of the two telescopic rods, so that each sliding block 322 can drive the telescopic rod connected thereto to move along the track of the sliding groove 321.

[0036] It should be noted that the sliding groove 321 can be set as a dovetail groove, and one end of the sliding block 322 connected to the sliding groove 321 can be set as a dovetail engaged with the dovetail groove, so as to increase the stability of the transportation unit 32 during transportation.

[0037] Furthermore, in order to simplify the structure of the feeding assembly 3, a sliding rod is arranged in one sliding groove 321, and a screw is arranged in the other sliding groove 321. The sliding rod is fixedly connected to the inner wall of the sliding groove 321, one end of the screw is rotatably connected to the inner wall of the sliding groove 321, and the other end is fixedly connected to the motor shaft of the motor. A through hole is arranged on the sliding block 322 embedded in the sliding groove 321 with a sliding rod, and the sliding rod is plugged into the through hole. A threaded hole is arranged on the sliding block 322 embedded in the sliding groove 321 with a screw, and the screw is screwed into the threaded hole. The rotation of the motor drives the screw to rotate. When the screw rotates, the sliding groove 321 limits the rotation of the sliding block 322, so that the sliding block 322 moves in the sliding groove 321, and then drives the clamping block 311 to move. Since the two clamping blocks 311 clamp the pipe to be processed by abutting against the surface of the pipe to be processed, when the clamping block 311 on the side with the motor moves, it will drive the clamping block 311 on the other side to move, thereby achieving the effect of clamping transmission.

[0038] Since the two clamping blocks 311 clamp the pipe to be processed in an abutting manner, when the motor drives the clamping block 311 on one side to move, the force between the clamping block 311 and the pipe to be processed changes from static friction to dynamic friction, resulting in the misalignment of the two clamping blocks 311 and the deflection of the pipe to be processed. In order to improve the stability of the two clamping blocks 311 during the clamping process, the clamping unit 31 also includes a front rod 314, one end of which is connected to the previous process and the other end extends to the position of the cutting assembly 4. The pipe to be processed is sleeved on the outer periphery of the front rod 314, and the front rod 314 plays a limiting role on the pipe to be processed, thereby improving the stability of the clamping transmission process of the pipe to be processed.

[0039] In one embodiment, the cutting assembly 4 includes a cutter 41, a third telescopic rod 43 and a cutter frame 42, the cutter frame 42 is fixed on the frame 1, and the cutter frame 42 is located between the clamping block 311 and the bending seat 21, the fixed end of the third telescopic rod 43 is fixedly connected to the cutter frame 42, and the telescopic end of the third telescopic rod 43 is fixedly connected to the cutter 41. After the bending assembly 2 bends part of the pipe to be processed on the bending seat 21 into a bent pipe, the third telescopic rod 43 drives the cutter 41 to cut the pipe to be processed, so as to separate the straight pipe part and the bent pipe part of the pipe to be processed.

[0040] In one possible implementation, a hydraulic lifting rod is further arranged at the bottom of the frame 1, a limit damper is fixedly connected to the bottom of the hydraulic lifting rod, a shock absorbing spring is arranged on the limit damper, and a foot pad is fixedly connected to the bottom of the shock absorbing spring.
