A blanking gap 34 is formed between the columns 33, and a blanking channel 312 connected to the blanking gap 34 is provided in the base 31. The bottom wall of the blanking channel 312 is inclined downward and penetrates the base 31 to one side. A plurality of punching seats 35 are slidably arranged on the end surface of the base 31 in a circular array along the positioning columns 33, and a punching block 351 is formed on the end surface of the punching seat 35 facing the positioning column 33. The driving mechanism 4 includes a driving column 42 which is arranged on the frame 1 and is located above the positioning column 33 and is transmission-connected to a hydraulic cylinder 41 provided on the frame 1. A plurality of driving blocks 43 in a trench-type manner are arranged on the driving column 42 and are aligned one-to-one with a plurality of punching seats 35 along a circular array of the driving column 42, and a driving groove 352 cooperating with the driving block 43 is provided on the punching seat 35.

[0024] Specifically, the supporting ring 32 and the positioning column 33 are arranged on the base 31: a supporting step 313 is formed on the side wall of the mounting hole 311, and a plurality of positioning blocks 314 of a circular array of positioning columns 33 are arranged on the side wall of the supporting step 313. A plurality of positioning grooves 321 matching the positioning blocks 314 are opened on the side surface of the supporting ring 32. The supporting ring 32 is placed on the supporting step 313 so that the positioning blocks 314 are placed in the positioning grooves 321. The supporting ring 32 is stabilized by the cooperation between the positioning blocks 314 and the positioning grooves 321. The mounting hole 311 is firmly held in place by the support column 315, a support column 315 is formed in the middle of the bottom wall of the mounting hole 311, a mounting groove 316 is formed on the end surface of the support column 315, a mounting column 331 matching the mounting groove 316 is formed at the lower end of the positioning column 33, the mounting column 331 is placed in the mounting groove 316 so that the positioning column 33 is placed on the support column 315, the positioning column 33 is stably held in the mounting hole 311 through the cooperation between the mounting column 331 and the mounting groove 316, and the above structure facilitates the assembly of the support ring 32 and the positioning column 33.

[0025] Specifically, the punching seat 35 is slidably arranged on the base 31: a sliding block 353 is formed on each side of the punching seat 35, and a plurality of fixed blocks 36 located on both sides of the punching seat 35 are opened on the end surface of the base 31, and a sliding groove 361 matching the sliding block 353 is opened on the side wall of the fixed block 36, and the sliding block 353 is placed in the sliding groove 361. In the above structure, the sliding of the punching seat 35 on the base 31 is realized by sliding the sliding block 353 in the sliding groove 361, and the assembly of the punching seat 35 is convenient.

[0026] In the above embodiment, the rodless cylinder 21 drives the mounting arm 23 to drive the claw 24 to move horizontally, and the slide cylinder 22 drives the mounting arm 23 to drive the claw 24 to move longitudinally. The separation pull ring clamped by the claw 24 is transferred to the blanking mechanism 3 through the cooperation of the rodless cylinder 21 and the slide cylinder 22, so that the separation pull ring is placed on the supporting ring 32 and the positioning column 33 passes through the separation pull ring. The positioning column 33 provides radial support for the separation pull ring during the blanking process to realize the loading of the separation pull ring. Then the hydraulic cylinder 41 drives the driving column 42 to drive the driving block 43 to move downward, so that the driving block 43 is gradually inserted into the driving groove 352 and simultaneously pushes a number of cutting The cutting seat slides toward the positioning column 33, and the cutting seat drives the cutting block to cooperate with the positioning column 33 to punch out a pull ring window on the separation pull ring. The waste material punched out falls into the blanking gap 34 and falls out of the base 31 after passing through the blanking channel 312, thereby realizing the punching of the separation window. After the driving block 43 and the punching seat 35 are reset, the air claw 24, driven by the cooperation of the rodless cylinder 21 and the slide cylinder 22, grabs the punched separation pull ring and takes it away from the punching mechanism 3, thereby realizing the unloading of the separation pull ring. Through the cooperation of the above-mentioned loading and unloading mechanism 2, the punching mechanism 3 and the driving structure, the automatic punching of the pull ring window of the separation pull ring is realized, which saves manpower and improves production efficiency.

[0027] Preferably, the upper end of the positioning block 314 is higher than the upper end of the supporting ring 32, and a plurality of positioning blocks 314 correspond to and match the claw hook notches on the separation pull ring. When the separation pull ring is placed on the supporting ring 32, the positioning block 314 is placed in the claw hook notch of the separation pull ring to provide circumferential positioning for the separation pull ring, thereby ensuring that the position of the pull ring window to be punched out of the separation pull ring is aligned with the punching block 351, and when the punching block 351 punches the pull ring window, the cooperation between the positioning block 314 and the claw hook of the separation pull ring prevents the separation pull ring from rotating in the circumferential direction, thereby ensuring the accuracy of the punching of the pull ring window and improving the quality of the punching of the pull ring window.

[0028] Preferably, a first limiting groove 317 located below the punching seat 35 is formed on the end surface of the base 31, and a first limiting portion 354 matching the first limiting groove 317 and disposed in the first limiting groove 317 is formed on the punching seat 35. When the punching seat 35 slides on the base 31 and drives the punching block 351 to punch the pull ring window, the first limiting portion 354 slides in the first limiting groove 317.

[0029] Preferably, a reset spring 37 is fixedly connected to the punching seat 35, and the other end of the reset spring 37 is fixedly connected to the fixed block 36. After the driving block 43 exits the driving groove 352 and resets, the punching seat 35 slides to the position where the first limiting portion 354 abuts against the side wall of the first limiting groove 317 under the action of the reset spring 37, ensuring that the punching seat 35 is completely reset, and ensuring that the driving block 43 can be accurately inserted into the driving groove 352 to push the cutting seat to slide during the next punching operation.

[0030] Preferably, the driving column 42 is hollow inside to form a sliding cavity 421, and a pressure column 44 is slidably arranged in the sliding cavity 421 and passes through the sliding cavity 421. A pressure spring 45 is arranged in the sliding cavity 421 and is located between the end face of the pressure column 44 and the top wall of the sliding cavity 421. When the driving block 43 is inserted into the driving groove 352 to push the cutting seat to perform the punching operation, the pressure column 44 is tightly pressed against the separation pull ring under the action of the pressure spring 45, preventing the separation pull ring from generating axial displacement during the process of punching the pull ring window, thereby ensuring the accuracy of punching the pull ring window.

[0031] Preferably, a second limiting portion 431 is formed on each side of the driving block 43, and two second limiting grooves 355 matching the second limiting portion 431 are opened on the side wall of the driving groove 352. When the driving block 43 is inserted into the driving groove 352, the second limiting portion 431 is inserted into the second limiting groove 355. Through the cooperation between the second limiting portion 431 and the second limiting groove 355, the relative movement between the driving block 43 and the cutting seat is guaranteed to be stable, thereby ensuring the accuracy of the punching of the pull ring window.
