[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Reference Figure 1 The utility model provides a device for punching round tubes with oblique end faces, including a frame 1 and a feeding mechanism 2 arranged on one side thereof, a punching bracket 3 is installed on the frame 1, a punching cylinder 7 is installed on the punching bracket 3, a punching die is installed at the lower end of the piston rod of the punching cylinder 7, a tube clamping mechanism 6 is arranged below the punching bracket 3, a positioning mechanism 4 is arranged between the feeding mechanism 2 and the punching bracket 3, and a transfer mechanism 5 is arranged between the positioning mechanism 4 and the punching mechanism.

[0019] During operation, the feeding mechanism 2 feeds the pipe 8 into the positioning mechanism 4, and the positioning mechanism 4 rotates the pipe 8 to rotate the position where the punching hole is required to be punched to the top through its end face features. The transfer mechanism 5 transfers the positioned pipe 8 to the pipe clamping mechanism 6 for fixation. After the punching operation is completed by the punching cylinder 7, the transfer mechanism 5 removes it to complete the unloading.

[0020] Reference Figure 2 The positioning mechanism 4 includes a rotating tube base 401 and a positioning base 404. A tube pressing mechanism is arranged on the top of the positioning base 404. Two sets of symmetrical support wheels 403 are installed on the rotating tube base 401. A servo motor 402 is installed on the side of the rotating tube base 401. The servo motor 402 drives the support wheels 403 to rotate. A tube pressing cylinder 405 is installed on the top of the positioning base 404. A support arm 406 is installed on the positioning base 404 below the tube pressing cylinder 405. One end of the support arm 406 is rotatably connected to the positioning base 404, and a pressing wheel 407 is installed on the other end. The piston rod of the tube pressing cylinder 405 is hinged to the middle part of the support arm 406. The pipe 8 is placed on the support wheel 403. The piston rod of the tube pressing cylinder 405 extends out through the pressing wheel 407 to press the pipe 8 against the support wheel 403, thereby driving the pipe to rotate through the servo motor 402.

[0021] Reference Figure 2 , Figure 3A material return cylinder 408 is installed on the positioning base 404 below the support arm 406, and a top block 409 is installed on the piston rod of the material return cylinder 408. A telescopic hole 410 is opened on the side of the top block 409 adjacent to the rotating tube base 401, and a sensor 414 is installed on the other side. A push rod 411 and a return spring 412 are installed in the telescopic hole 410. The push rod 411 is directly opposite to the detection end of the sensor 414, and the return spring 412 is arranged on the push rod 411. One end of the return spring 412 is connected to the push rod 411, and the other end is connected to the inner wall of the telescopic hole 410.

[0022] The end face of the pipe 8 in this embodiment is an inclined surface. During operation, the top block 409 is pressed against the end face of the pipe 8 during positioning. As the pipe 8 rotates, its tip contacts the push rod 411 and pushes the push rod 411 toward the sensor 414. When the sensor 414 is a proximity sensor, it can receive a signal indicating that the push rod 411 is approaching, thereby controlling the servo motor 402 to stop rotating. In addition, the sensor 414 can also adopt a stroke sensor, and the push rod 411 is connected to the input end of the sensor 414. When the raised part of the end face of the pipe 8 pushes the push rod 411, the sensor 414 outputs a stroke signal. When the stroke signal is consistent with the set value, the servo motor 402 is controlled to stop rotating. The stroke sensor is more suitable for the end face of the pipe 8 with several protrusions of different heights to locate the position of its punching.

[0023] Reference Figure 4 The tube clamping mechanism 6 includes a tube clamping support plate 602 and a mold base 601, a tube support 603 is installed between the tube clamping support plate 602 and the mold base 601, a tube clamping cylinder 604 is installed on the tube clamping support plate 602, a positioning seat 605 is installed on the piston rod of the tube clamping cylinder 604, the inner diameter of the positioning seat 605 is equal to the outer diameter of the tube 8, a liner column 607 and a demolding cylinder 606 are arranged on the mold base 601, the outer diameter of the liner column 607 is equal to the inner diameter of the tube 8, and a through hole matching the die is arranged thereon, a demolding plate 608 is installed on the piston rod of the demolding cylinder 606, and the demolding plate 608 is sleeved on the liner column 607.

[0024] During operation, the transfer mechanism 5 transfers the pipe 8 to the pipe support 603, the piston rod of the pipe clamping cylinder 604 extends out of the positioning seat 605 and is sleeved on one end of the pipe 8, and the other end of the pipe 8 is sleeved on the liner column 607, the piston rod of the punching cylinder 7 extends out to complete the punching, and the demolding cylinder 606 pushes the demolding plate 608 to remove the pipe 8 from the liner column 607.
