The top wall assembly 3 includes an oil pressure box 301 connected to the oil pipe 202, and the oil pressure box 301 is arranged in a hexagonal structure. A plurality of fixed cylinders 302 are connected and fixedly connected to the side wall of the oil pressure box 301, and a plurality of fixed cylinders 302 are slidably connected inside the plurality of fixed cylinders 302.

When the displacement plug 303 moves, it will drive the push plate 401 to move, so that the push plate 401 drives the arc plate 406 to fit the inner wall of the pipe through the capillary 404. At this time, the displacement plug 303 will continue to move, so that the hydraulic fluid inside the limiting cylinder 402 is injected into the top module 405 through the capillary 404, so that the top module 405 generates pressure, causing the air bag 408 to expand and fit the inner wall of the pipe. In this way, the fitting area with the inner wall of pipes of different diameters can be increased, and the stability of punching and anti-depression can be improved.

[0028] The oil filling assembly 5 includes a pressurizing cylinder 501 fixedly connected to one of the circular frames 102, a rubber plug 502 is slidably connected inside the pressurizing cylinder 501, a threaded sleeve 503 is fixedly connected to the side wall of the rubber plug 502, an end of the pressurizing cylinder 501 away from the circular frame 102 is fixedly connected to a motor 504, an output end of the motor 504 is fixedly connected to a screw rod 505, and the screw rod 505 is threadedly connected to the threaded sleeve 503, a limiting plate 506 is fixedly connected inside the pressurizing cylinder 501, and the threaded sleeve 503 penetrates the limiting plate 506.

[0029] Example 2: Please refer to Figures 9 and 10Based on Example 1, the control component 6 includes a protective cylinder 601 fixedly connected to the side wall of one of the fixed bases 101, a driven rotating rod 602 is rotatably connected to one of the fixed bases 101, and the driven rotating rod 602 is rotatably connected to the pulley 106, a moving sleeve 603 is slidably connected to the driven rotating rod 602, and both ends of the moving sleeve 603 are fixedly connected to a resistance-increasing conical block 604, and the outer surface of the resistance-increasing conical block 604 and the inner surfaces of the inner groove cone sleeve 605 and the fixed cone sleeve 606 are all provided with anti-slip patterns, so that To increase the friction between the inner groove cone sleeve 605, the fixed cone sleeve 606 and the resistance increasing cone block 604, the inner groove cone sleeve 605 and the fixed cone sleeve 606 matching the resistance increasing cone block 604 are fixedly connected to one end of the pulley 106 close to the ring sleeve 607 and the side wall of the fixed base 101, respectively, the movable sleeve 603 is rotatably connected to the ring sleeve 607, the side wall of the fixed base 101 is fixedly connected to an electromagnet 608 that magnetically repels the ring sleeve 607, and the side wall of the ring sleeve 607 is fixedly connected to two limit rods 609, and the two limit rods 60 9 are all through the fixed base 101 and are fixedly connected with a spring plate 610, and a thrust spring 611 is fixedly connected between the spring plate 610 and the fixed base 101. When the electromagnet 608 is not started, the resistance-increasing conical block 604 is in contact with the fixed conical sleeve 606. At this time, the rotation of the rotating shaft 105 will not affect the driven rotating rod 602. Therefore, when the electromagnet 608 is not started, the dual-axis motor 104 can only drive the belt ring 107 on the same side of the rotating block 103 to rotate, and then can only drive the rotating block 103 to rotate. When the electromagnet 608 is started, When the rotating block 103 and the annular air box 204 rotate at the same time, the electromagnet 608 will push the resistance increasing conical block 604 to fit with the inner groove conical sleeve 605, so that when the rotating shaft 105 rotates, the driven rotating rod 602 can be driven to rotate through the contact between the inner groove conical sleeve 605 and the resistance increasing conical block 604, and finally the driven rotating rod 602 can drive the annular air box 204 to rotate through the pulley 106 and the belt 108. When the rotating block 103 and the annular air box 204 rotate at the same time, the electric push rod 208 is repeatedly started to perform a circular motion trajectory to punch the pipe fittings, thereby improving the punching efficiency.

[0030] The working principle of the present invention is: When processing the pipe fittings in the present invention, first, the staff uses a clamp to fix the pipe fittings, wherein the clamp is a prior art and will not be described in detail here. The working state of the device is as follows: Figure 1 As shown, the worker then moves the clamp so that one end of the pipe is located inside the annular block 201.

[0031] Then the staff starts the motor 504. When the motor 504 starts, the motor 504 drives the screw rod 505 to rotate, and the thread action drives the rubber plug 502 to move, so that the rubber plug 502 injects the hydraulic oil inside the pressurizing cylinder 501 into the oil pipe 202 and the oil pipe 203. When the motor 504 reverses, the hydraulic oil can be drawn back in the reverse direction.

[0032] After the hydraulic oil enters the oil pressure box 301 through the oil pipe 202, the hydraulic oil pushes all the shift plugs 303 to move, driving the multiple threaded rods 304 to move toward the inner wall of the pipe fitting. During the movement of the multiple threaded rods 304, the bevel gears 305 threadedly connected thereto are also driven to move, so that the multiple bevel gears 305 drive a synchronous bevel wheel 308 to rotate, so that the multiple threaded rods 304 can be meshed with the synchronous bevel wheel 308 and the multiple bevel gears 305, so that the multiple threaded rods 304 can move synchronously, and then the multiple threaded rods 304 can drive the multiple mold assemblies 4 to push the inner wall of the pipe fitting together.

[0033] When the displacement plug 303 moves, it will also drive the push plate 401 to move, so that the push plate 401 drives the arc plate 406 to fit the inner wall of the pipe through the capillary 404. At this time, the displacement plug 303 will continue to move, so that the hydraulic fluid inside the limiting cylinder 402 is injected into the top module 405 through the capillary 404, so that the top module 405 generates pressure, causing the airbag 408 to expand and fit the inner wall of the pipe. In this way, the fitting area with the inner wall of pipes of different diameters can be increased, thereby improving the stability of punching and anti-depression.

[0034] After the hydraulic oil enters the annular air box 204 through the oil pipe 203, the oil inside the annular air box 204 will flow to the inside of the mounting groove 205 connected thereto, thereby driving the movable plug 206 to move, so that the top cylinder 207 is attached to the surface of the stainless steel pipe, and then the electric push rod 208 is started to push the punch 209 to punch the surface of the pipe fitting. The purpose of moving the movable plug 206 is to adapt to pipe fittings with different outer diameters.

[0035] When the staff needs to adjust the processing hole shape, first, the staff turns on the motor 504 and reverses it to pump back the hydraulic oil in the reverse direction. When the hydraulic oil is pumped back in the reverse direction, the moving plug 206 and the shifting plug 303 are reset. Then, the staff starts the dual-axis motor 104, and the dual-axis motor 104 drives the pulley 106 to rotate through the rotating shaft 105, so that the pulley 106 drives the belt ring 107 to rotate through the belt 108, and the belt ring 107 drives the rotating block 103 to rotate. The rotating block 103 rotates through the two The oil pipe 203 drives the annular air box 204 to rotate, so that the annular air box 204 can be connected with different installation grooves 205. Since the punches 209 inside each installation groove 205 are different, the purpose of switching the punches 209 is achieved and the adjustment of the hole shape is completed. During the rotation of the rotating block 103, the top wall assembly 3 is also driven to rotate through the oil pipe 202, so that during the switching process of the punch 209, the mold core 407 of the corresponding shape can also support the inner wall of the pipe fitting to prevent the pipe fitting from being dented.

[0036] In addition, when the staff needs to perform annular punching, the staff starts the electromagnet 608, and the electromagnet 608 will push the resistance-increasing conical block 604 to fit together with the inner groove cone sleeve 605, so that when the rotating shaft 105 rotates, the contact between the inner groove cone sleeve 605 and the resistance-increasing conical block 604 can drive the driven rotating rod 602 to rotate, and finally the driven rotating rod 602 can drive the annular air box 204 to rotate through the pulley 106 and the belt 108. When the rotating block 103 and the annular air box 204 rotate at the same time, the electric push rod 208 is repeatedly started to perform a circular motion trajectory to punch the pipe fittings, thereby improving the punching efficiency.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
