The conveying seat 302 is connected to the conveying frame 3 by a sliding connection, and a suction cup 304 is fixedly connected to the inner side of the conveying seat 302 through a conveying column 303.

[0030] Specifically, first, the device base 1 is placed at the specified position, and the hardware pins that need to be punched are placed in the device. The hardware pins are punched by the punching mechanism 4. The support frame 2 supports the conveying frame 3, and the conveying frame 3 supports the telescopic cylinder 301 and the conveying seat 302. After the punching is completed, the conveying seat 302 is driven by the telescopic cylinder 301 to move on the outside of the conveying frame 3, and then the conveying column 303 is driven to move by the conveying seat 302, and the suction cup 304 is driven to move by the conveying column 303, and the hardware pins can be driven to move by the suction cup 304, and the hardware pins are moved to the inside of the bending mechanism 6, and the hardware pins are bent by the bending mechanism 6.

[0031] Then, see Figure 1 , Figure 2 as well as Figure 4 A punching mechanism 4 is provided on the top of the device base 1 and in front of the support frame 2;

[0032] The punching mechanism 4 is used to quickly punch holes in the hardware pins. The specific structure of the punching mechanism 4 is as follows:

[0033] The punching mechanism 4 includes four sets of punching frames 401, a lifting cylinder 402, a connecting seat 403, an L-shaped limit block 404, a punching seat 405, a limit frame 406, a placement hole 407, a punching drill 408 and a fixing ring 409. The punching frame 401 is arranged on the top of the device base 1 and is located in front of the support frame 2. Lifting cylinders 402 are arranged on the left and right sides of the top of the punching frame 401. The two sets of lifting cylinders 402 penetrate the punching frame 401 and are connected to the connecting seat 403 through two sets of bolts. The bottom of the connecting seat 403 is fixedly connected with two sets of L-shaped limit blocks 404. The bottom of the connecting seat 403 is provided with a punching seat 40 5. A limiting frame 406 is fixedly connected to the top of the punching seat 405 and located between the two groups of L-shaped limiting blocks 404. Three groups of placement holes 407 are opened inside the limiting frame 406 and the punching seat 405. Punching drill bits 408 are arranged inside the three groups of placement holes 407. The tops of the three groups of punching drill bits 408 are fixedly connected with fixing rings 409.

[0034] Specifically, the punching mechanism 4 is used to punch holes on the hardware pins. First, the punching drill bit 408 is placed in the placement hole 407 in the limiting frame 406. The fixing ring 409 on the top of the punching drill bit 408 limits the punching drill bit 408. The limiting frame 406 is slid between the two groups of L-shaped limiting blocks 404, so that the thread grooves in the three groups of fixing rings 409 coincide with the thread grooves in the connecting seat 403. The bolts are screwed into the thread grooves, and the punching drill bit 408 is limited and fixed by the bolts. The connecting seat 403 is installed at the bottom of the lifting cylinder 402 and is located below the punching frame 401. The punching frame 401 supports the lifting cylinder 402. The cylinder 402 drives the connecting seat 403 to rise and fall, and then drives the punching seat 405 to rise and fall through the connecting seat 403, and then drives the three sets of punching drills 408 to move through the punching seat 405, and punches the hardware pins through the punching drill 408. When the punching drill 408 is damaged, the connecting seat 403 is removed from the bottom of the lifting cylinder 402 and the punching frame 401, and the bolts are unscrewed from the threaded grooves in the connecting seat 403, and the bolts fix the punching drill 408, and then the limit frame 406 is slid out of the two sets of L-shaped limit blocks 404, and then the punching drill 408 is taken out from the placement hole 407, and the punching drill 408 can be repaired and replaced.

[0035] Also, see Figure 1 and Figure 3 A bending mechanism 6 is provided on the top of the device base 1 and in front of the conveying platform 5;

[0036] The bending mechanism 6 is used to stably bend the hardware pins. The specific structure of the bending mechanism 6 is as follows:

[0037] The bending mechanism 6 includes a first bending seat 601, a second bending seat 602, a hydraulic cylinder 603, a lifting platform 604, a connecting rod 605, a pressure plate 606, a buffer spring 607, a first bending block 608 and a second bending block 609. The first bending seat 601 is fixedly connected to the top of the device base 1 and is located in front of the conveying platform 5. The front of the first bending seat 601 is fixedly connected to the second bending seat 602. The device base 1 is connected to the lifting platform 604 through four groups of hydraulic cylinders 603. The bottom of the lifting platform 604 slides through four groups of connecting rods 605. A pressure plate 606 is connected, and a buffer spring 607 is sleeved on the outside of the four groups of connecting rods 605 and between the lifting platform 604 and the pressure plate 606. The bottom of the lifting platform 604 and the left and right sides of the first bending seat 601 are fixedly connected with the first bending block 608, and the bottom of the lifting platform 604 and the left and right sides of the second bending seat 602 are fixedly connected with the second bending block 609. The inside of the pressure plate 606 and the corresponding positions of the two groups of first bending blocks 608 and the two groups of second bending blocks 609 are respectively provided with a first bending groove and a second bending groove.

[0038] Specifically, the punched metal pins are bent by the bending mechanism 6, and the metal pins are transported to the first bending seat 601 through the conveying frame 3. At this time, the lifting platform 604 is driven to rise and fall by the hydraulic cylinder 603. When the lifting platform 604 is lifted and lowered, the connecting rod 605 drives the pressing plate 606 to move, and then the pressing plate 606 is squeezed on the top of the first bending seat 601 and the second bending seat 602. At this time, the lifting platform 604 continues to descend to squeeze the buffer spring 607, and respectively makes the two groups of first bending blocks 608 pass through the two groups of first bending grooves, and the two sides of the metal pins are bent by the two groups of first bending blocks 608, and at the same time, the two groups of second bending blocks 609 pass through the two groups of second bending grooves to bend the two sides of the metal pins.

[0039] In this embodiment, the implementation scenario is specifically as follows: in actual use, first place the device base 1 at the specified position, place the hardware pins that need to be punched in the device, and perform punching processing on the hardware pins through the punching mechanism 4. The support frame 2 supports the conveying frame 3, and the conveying frame 3 supports the telescopic cylinder 301 and the conveying seat 302. After the punching is completed, the conveying seat 302 is driven by the telescopic cylinder 301 to move on the outside of the conveying frame 3, and then the conveying column 303 is driven to move through the conveying seat 302, and the suction cup 304 is driven to move through the conveying column 303, and the hardware pins can be moved by the suction cup 304, and the hardware pins are moved to the inside of the bending mechanism 6, and the hardware pins are bent by the bending mechanism 6. Compared with the existing punching device, the utility model can improve the overall practicality of the punching device through design.
