[0038] The following will further elaborate on the present utility model in conjunction with the attached Figures 1 to 4 but it is not a limitation to the present utility model.

[0039] It includes a processing component 1 and a material pushing component 2. One end of the material pushing component 2 is fixedly arranged on the processing component 1, and the other end of the material pushing component 2 extends in the opposite direction of the processing component 1, and the end of the material pushing component 2 away from the processing component 1 is supported by a rear frame 4; the processing component 1 includes at least two processing dies 11, and two groups of clamping components 3 are arranged on the material pushing component 2. Each group of clamping components 3 corresponds to the processing die 11, and the clamping component 3 is arranged opposite to the processing die 11.

[0040] Specifically, when processing the pipe, the processing component 1 is used to fix the pipe to prevent the position of the pipe from deviating, and at the same time perform stamping processing on the pipe. Setting two processing dies 11 can process more pipes simultaneously. During actual processing, the two processing dies 11 can achieve different processing procedures. For example, one processing die 11 performs stamping and punching, while the other processing die 11 performs blanking operation, so as to realize multiple functions of one device. The material pushing component 2 cooperates with the processing component 1. The processing component 1 is used to process the pipe, and the material pushing component 2 is used to push the pipe to move. The two groups of clamping components 3 on the material pushing component 2 are used to clamp the ends of the pipe, so as to further fix the pipe and prevent the pipe from warping or bending during processing.

[0041] In this embodiment, the processing component 1 further includes a processing tool holder 12 and a processing drive 13. A processing position 111 is arranged in the processing die 11. The processing position 111 is a through groove penetrating the processing die 11, and the processing position 111 corresponds to the clamping component 3.

[0042] Specifically, the processing position 111 is used to accommodate the pipe to be processed. Placing the pipe in the through groove can position the pipe. After the pipe is placed in the through groove, the pipe moves along the extension direction of the through groove to achieve stamping of different parts. The through groove is used to limit the movement of the pipe in the plane direction, and the clamping component 3 clamps the end of the pipe to prevent the pipe from rotating and causing inaccurate punching positions.

[0043] In this embodiment, the processing tool holder 12 is arranged above the processing die 11, and the processing tool holder 12 moves towards the processing die 11.

[0044] Specifically, the processing tool holder 12 is used to process corresponding holes on the pipe. When processing, the processing tool holder 12 punches the pipe. After punching, there will be corresponding pipe fragments. If the processing tool holder 12 is placed below the processing die 11, the pipe fragments will cover the processing tool holder 12 due to the principle of gravity, which will affect the subsequent punching processing, such as uneven hole edges, etc. While placing the processing tool holder 12 above the processing die 11, after punching is completed, the pipe fragments are placed inside the pipe and at the bottom inside the pipe due to gravity, and the pipe fragments do not contact the processing tool holder 12, so it will not cause the processing tool holder 12 to affect the holes during subsequent processing.

[0045] In this embodiment, the processing tool holder 12 includes a fixing plate 121, a processing tool head 122, and a guide rod 123. The fixing plate 121 is arranged above the processing die 11, and the processing tool head 122 and the guide rod 123 are arranged between the fixing plate 121 and the processing die 11. One end of the processing tool head 122 and one end of the guide rod 123 are fixedly connected to the fixing plate 121, and the guide rod 123 is arranged on both sides of the processing tool head 122.

[0046] Specifically, holes corresponding to the processing tool head 122 and the guide rod 123 are arranged in the processing die 11, and the processing tool head 122 and the guide rod 123 are placed in the holes. When processing the pipe, the processing tool head 122 contacts the pipe, thereby punching out a shape corresponding to the processing tool head 122 in the pipe. It should be noted that in this embodiment, the shape of the processing tool head 122 is not limited and can be circular, square, triangular, or polygonal, etc. When the fixing plate 121 drives the processing tool head 122 to move, it is guided by the guide rod 123 to prevent the processing tool head 122 from running off during processing, resulting in deformation of the processed holes.

[0047] Meanwhile, the guide rod 123 can also ensure the machining stability of the machining tool rest 12. When the machining tool bit 122 processes the pipe, punching is performed by extrusion. During extrusion, a part of the pipe will have a rebounding force that rebounds onto the machining tool rest 12, pushing the machining tool rest 12 upward. And due to the pressing of the machining drive 13 on the upper part of the machining tool rest 12, the machining tool rest 12 deforms to both sides. In order to prevent the machining tool rest 12 from being damaged by a large force, during machining, the guide rod 123 can share a part of the rebounding force borne by the machining tool rest 12, thus ensuring the stability of the machining tool rest 12.

[0048] In this embodiment, the machining die 11 is provided with at least two machining positions 111. The end of the machining tool bit 122 moves into the machining positions 111, and the number of machining tool bits 122 corresponds to the number of machining positions 111.

[0049] Specifically, each machining die 11 has two machining positions 111 and two machining tool bits 122. Setting two machining positions 111 and two machining tool bits 122 can process more pipes simultaneously, further improving the machining efficiency.

[0050] In this embodiment, the machining assembly 1 further includes a support frame 14, and the machining die 11 and the machining tool rest 12 are both arranged inside the support frame 14.

[0051] Specifically, since the machining tool rest 12 and the machining die 11 perform mechanical movements, when some debris or other things come into contact with the machining tool rest 12 during machining, it will affect the machining of the machining tool rest 12, resulting in a decline in the punching quality. To avoid this situation, the support frame 14 is provided for protection.

[0052] Meanwhile, the support frame 14 also supports the machining drive 13.

[0053] In this embodiment, the machining drive 13 is arranged on the support frame 14 and is disposed opposite to the machining die 11. The output end of the machining drive 13 passes through the support frame 14 and is connected to the machining tool rest 12, and the machining drive 13 drives the machining tool rest 12 to move up and down.

[0054] Specifically, in some embodiments, the machining drive 13 can be a hydraulic cylinder, a pneumatic cylinder or a motor. In this embodiment, the machining drive 13 is a hydraulic cylinder. The hydraulic cylinder has a large impact force and can process pipes of various materials, thus expanding the scope of use of this equipment.

[0055] In some embodiments, the material pushing assembly 2 includes a moving slide rail 21. An installation plate 22 is arranged on the moving slide rail 21. Each set of clamping assemblies 3 includes a first clamping part 31 and a second clamping part 32, and the first clamping part 31 and the second clamping part 32 are symmetrically arranged on both sides of the installation plate 22.

[0056] Specifically, the first clamping portion 31 and the second clamping portion 32 are both arranged on both sides of the mounting plate 22, and are uniformly moved through the mounting plate 22, thereby ensuring the consistency of processing, and the movable slide rail 21 is used for the movement of the mounting plate 22 and for guiding, so that the mounting plate 22 always moves in one direction.

[0057] In this embodiment, the pusher assembly 2 further includes a drive motor 23 , which is transmission-connected to the movable slide rail 21 , and the movable slide rail 21 drives the mounting plate 22 to move.

[0058] Specifically, in some embodiments, the drive motor 23 can be a servo motor, a stepper motor or other drivers, but in this embodiment, the drive motor 23 is a servo motor. By compiling the drive motor 23, the drive motor 23 drives the movable slide rail 21 and the mounting plate 22 on the movable slide rail 21 to move according to the set distance, thereby realizing a punching process of multiple specifications.

[0059] In this embodiment, the first clamping part 31 and the second clamping part 32 both include a first connecting block 33, a second connecting block 34 and a clamping cylinder 36, the cylinder body of the clamping cylinder 36 is fixedly connected to the first connecting block 33, the second connecting block 34 is arranged on the first connecting block 33 and is located between the clamping cylinder 36 and the processing mold 11, and the output end of the clamping cylinder 36 is provided with a third connecting block 35, the end of the third connecting block 35 passes through the second connecting block 34, and the end of the third connecting block 35 is provided with an upper clamping block 37, and the second connecting block 34 is provided with a lower clamping block 38, the upper clamping block 37 and the lower clamping block 38 are arranged opposite to each other, and the clamping cylinder 36 drives the upper clamping block 37 to move closer to the lower clamping block 38.

[0060] Specifically, in the present embodiment, the first clamping part 31 and the second clamping part 32 form a group of clamping components 3, each group of clamping components 3 corresponds to the processing mold 11, and the first clamping part 31 and the second clamping part 32 are respectively opposite to the through grooves in the processing mold 11. In the present embodiment, two groups of clamping components 3 are arranged, and the two groups of clamping components 3 are arranged on the mounting plate 22, and are uniformly dispatched through the mounting plate 22.

[0061] During processing, the pipe is first passed through the through groove, and then the end of the pipe is abutted against the first clamping part 31 or the second clamping part 32. The output end of the clamping cylinder 36 extends to drive the third connecting block 35 to move downward, and at the same time, the upper clamping block 37 moves closer to the lower clamping block 38 to clamp the pipe, thereby fixing the pipe.
