Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The embodiment of the present application provides an automatic feeding device for a punch press, thereby solving the problem of manually pushing bearing rings one by one into a processing table, which is time-consuming and labor-intensive. When inserting the bearing rings, it is easy to insert multiple bearing rings at one time, causing the machine to become stuck, thereby reducing production efficiency. In addition, because the distance to the workbench when inserting the bearing rings is too close, it will cause a safety hazard to the operator's hands.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The utility model embodiment discloses an automatic feeding device for a punching machine.

[0031] According to the attached Figure 1-6 As shown, it includes a body 1 and a material discharge chute 3 installed on one side of the bottom of the body 1, an operating table 2 is fixedly installed on the bottom of the body 1, and a driving mechanism 4 is arranged on the top of the body 1. The driving mechanism 4 includes a clamping block 401, a first movable block 402, a motor wheel 403, an eccentric shaft 404 and a transverse groove 405;

[0032] When the device is used, the pedal 10 is stepped on to transmit an electric signal to the inside of the machine body 1, the motor wheel 403 is started to rotate one circle, and then stops. The pedal 10 is stepped on several times, the motor wheel 403 rotates several times, and the eccentric shaft 404 of the motor wheel 403 slides inside the first movable block 402. The eccentric shaft 404 drives the first movable block 402 to slide vertically. The bottom of the first movable block 402 is connected to the second movable block 502 through the movable rod 501. When the first movable block 402 slides up and down, it drives the second movable block 502 to slide together. The movable rod 501 is rotatably connected to the inside of the second movable block 502, and the second movable block 502 drives the first movable rod 601 and the wedge block 602. Sliding together, the wedge block 602 moves downward, and its arc surface pushes the slider 604 forward, and the slider 604 drives the second movable rod 605 and the push rod 606 on the top of the second movable rod 605 to slide forward together. At the same time, because the push rod 606 withdraws from the discharge trough of the pusher 7, the bearing ring placed in the discharge chute 3 falls into the discharge trough, the wedge block 602 moves upward, and the tension spring 9 set inside the slider 604 and the fixed pile 8 is tightened, and the slider 604 is pulled back to its original position, and the push rod 606 is inserted into the discharge trough of the pusher 7 to push out the bearing ring inside. At the same time, because the push rod 606 blocks the discharge chute 3, the bearing ring cannot fall into the discharge trough, completing the purpose of falling into the discharge trough one at a time;

[0033] The motor wheel 403 is arranged on one side of the machine body 1, the eccentric shaft 404 is rotatably connected to one side of the motor wheel 403, the transverse groove 405 is opened inside the first movable block 402, the eccentric shaft 404 slides inside the first movable block 402, and the first movable block 402 is vertically slidably connected inside the two sets of clamping blocks 401;

[0034] A wedge block 602 is provided on one side of the first movable block 402, and a slider 604 is provided below the wedge block 602. The inclined arc surface of the wedge block 602 abuts against the slider 604. A push rod 606 is fixedly connected to one side of the slider 604, and the push rod 606 faces the bottom end of the unloading chute 3.

[0035] A transmission mechanism 5 is provided at the bottom of the driving mechanism 4, and the transmission mechanism 5 includes a movable rod 501, a second movable block 502 and a rotating rod 503;

[0036] One end of the movable rod 501 is fixedly mounted on the bottom of the first movable block 402 , and the other end of the movable rod 501 is rotatably connected to the outer surface of the rotating rod 503 , and the rotating rod 503 is fixedly mounted inside the second movable block 502 .

[0037] A material pushing mechanism 6 is provided on one side of the transmission mechanism 5, and the material pushing mechanism 6 includes a first moving rod 601, a fixing plate 603 and a second moving rod 605;

[0038] The first movable rod 601 is fixedly mounted on one side of the second movable block 502, the wedge block 602 is fixedly mounted on one side of the first movable rod 601, the fixed plate 603 is fixedly mounted on one side of the top of the operating table 2, the second movable rod 605 is fixedly mounted on one side of the slider 604, and the push rod 606 is fixedly mounted on the top of the second movable rod 605.

[0039] A groove is formed inside the fixing plate 603, and the slider 604 slides inside the groove.

[0040] A fixing pile 8 is fixedly installed at the end of the operating platform 2 , a tension spring 9 is fixedly installed inside the fixing pile 8 , and the other end of the tension spring 9 is fixedly installed at one end of the sliding block 604 .

[0041] A pushing platform 7 is fixedly installed at the bottom of the unloading chute 3, and a discharging trough is opened on the top of the pushing platform 7. The push rod 606 is movably inserted in the discharging trough. The push rod 606 slides inside the discharging trough and blocks the unloading chute 3 at the same time. When the push rod 606 withdraws from the pushing platform 7, the bearing ring falls from the unloading chute 3 into the discharging trough on the top of the pushing platform 7, and then the push rod 606 enters the discharging trough and pushes the bearing ring into the inside of the discharging trough, completing the purpose of dropping one at a time and pushing away one bearing ring at a time, so that it will not block the discharging trough and affect the efficiency.

[0042] A pedal 10 is disposed at the bottom of the machine body 1 , and the pedal 10 is electrically connected to the machine body 1 .

[0043] A sliding groove is provided on one side of the clamping block 401 facing the first movable block 402, and extension blocks are fixedly installed on both sides of the first movable block 402 and the second movable block 502. The extension blocks slide inside the sliding groove. The addition of the extension blocks allows the first movable block 402 and the second movable block 502 to slide smoothly inside the clamping block 401 without position deviation.
