These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0021] As Figures 1 to 5 shown, an automatic deviation rectification mechanism for a punching machine provided by the present utility model includes an operating table 1. A support back plate 2 is fixedly connected to the rear end of the top of the operating table 1. An electric telescopic rod 3 is fixedly installed in the inner cavity of the support back plate 2. An installation mechanism 4 is arranged at the bottom of the electric telescopic rod 3. A limiting mechanism 5 is arranged on the top of the operating table 1. A ball 7 is movably connected to the right side of the top of the operating table 1.
[0022] Refer to Figures 1 to 5, the installation mechanism 4 includes a mold base 401, a support cross bar 402, a connecting sleeve block 403, a support longitudinal bar 404, an installation base 405, a horizontal spring 406 and a vertical spring 407. The mold base 401 is fixedly connected to the bottom end of the electric telescopic rod 3. The support cross bar 402 is fixedly connected to the inner cavity of the mold base 401. The connecting sleeve block 403 is movably sleeved on the surface of the support cross bar 402. The support longitudinal bar 404 is fixedly connected to the inner side of the connecting sleeve block 403. The installation base 405 is movably connected to the surface of the support longitudinal bar 404. The horizontal spring 406 is movably sleeved on both ends of the support cross bar 402. The vertical spring 407 is movably sleeved on both ends of the support longitudinal bar 404. The number of the support cross bars 402 is two, and the support cross bars 402 are respectively fixedly connected to the front and rear sides of the inner cavity of the mold base 401. The number of the support longitudinal bars 404 is at least three, and the support longitudinal bars 404 are fixedly connected to the inner side of the connecting sleeve block 403 at equal intervals. The outer sides of the horizontal springs 406 are respectively fixedly connected to the left and right sides of the inner cavity of the mold base 401. The inner sides of the horizontal springs 406 are respectively fixedly connected to the left and right sides of the connecting sleeve block 403. The outer side of the vertical spring 407 is fixedly connected to the inner side of the connecting sleeve block 403. The inner side of the vertical spring 407 is fixedly connected to the outer side of the installation base 405. The limiting mechanism 5 includes a connecting groove 501, a driving threaded rod 502, a material limiting block 503, a mold limiting baffle 504 and a driving motor 505. The connecting groove 501 is opened at the top of the operation table 1. The driving threaded rod 502 is movably connected to the inner cavity of the connecting groove 501. The material limiting block 503 is threadedly sleeved on the surface of the driving threaded rod 502. The mold limiting baffle 504 is fixedly connected to the top end of the material limiting block 503. The driving motor 505 is fixedly installed at the front end of the operation table 1. The front end of the connecting groove 501 is fixedly connected to the output end of the driving motor 505. The lower part of the material limiting block 503 is movably connected to the inner cavity of the connecting groove 501. A fillet is opened on the right side of the upper end of the material limiting block 503.
[0023] Adopting the above solution: Through the arrangement of the horizontal spring 406 and the vertical spring 407, the installation base 405 can be quickly reset, and there is no reset energy consumption. Through the fillet on the right side of the upper end of the material limiting block 503, the material can move along the fillet, move to the rear side of the material limiting block 503 and fit with the surface of the material limiting block 503, so as to correct the position of the material through the material limiting block 503. Through the arrangement of the mold limiting baffle 504, the stamping die 6 can be limited during the downward movement, so that the stamping die 6 moves to the specified working position during the downward pressing process.
[0024] Reference Figures 1 to 5, a stamping die 6 is fixedly installed at the bottom end of the installation base 405. The front end of the stamping die 6 is movably connected to the surface of the die limit baffle 504. A storage drawer 8 is movably connected inside the front end of the operation table 1. A maintenance back plate 9 is fixedly installed on the back of the operation table 1 by bolts. The bottom end of the operation table 1 is fixedly connected to a support vertical plate 10, and the bottom end of the support vertical plate 10 is fixedly connected to a device bottom plate 11.
[0025] With the above solution: through the setting of the storage drawer 8, some accessories can be stored and placed to avoid the influence of messy accessories on the operation of this device. Through the setting of the maintenance back plate 9, the internal components of this device can be repaired and replaced. Through the setting of the support vertical plate 10 and the device bottom plate 11, this device can be supported and the bottom end of the operation table 1 will not contact the ground and cause wear, improving the service life of this device.
[0026] Working principle:
[0027] During use, the components of this device are operated and controlled through the PLC control panel. According to the actual usage requirements, the corresponding stamping die 6 is installed at the bottom of the installation base 405 for use. According to the usage requirements of the stamping die 6, the driving motor 505 is controlled to work to drive the driving threaded rod 502 to rotate. The rotation of the driving threaded rod 502 drives the material limiting block 503 and the die limiting baffle 504 to move to the specified position as required. Then, the stamping material is pushed from the right side of the operating table 1 to the lower side of the stamping die 6. During the pushing process, the friction between the material and the operating table 1 is reduced by the ball 7, making it easier to push the material and preventing scratches on the lower surface of the material due to friction. When the material reaches the right side of the material limiting block 503, the material is moved along the surface of the material limiting block 503 by the material limiting block 503, making the material fit the surface of the material limiting block 503, so that the placement position of the material is at the specified position as required. Then, the electric telescopic rod 3 is controlled to work to drive the die base 401 to move up and down. The movement of the die base 401 drives the installation base 405 to move, thereby driving the stamping die 6 to move. The stamping die 6 moves downward to stamp the material. During the downward movement of the stamping die 6, the front side of the stamping die 6 first contacts the rear side of the die limiting baffle 504. The stamping die 6 is driven to move backward by the die limiting baffle 504. The movement of the stamping die 6 drives the installation base 405 to move. The movement of the installation base 405 drives the longitudinal spring 407 to contract, so that the downward pressure position of the stamping die 6 is adjusted by the die limiting baffle 504, ensuring that the material and the stamping die 6 are in the corresponding positions during the downward pressure process and preventing deviation. During the upward movement of the die base 401 driven by the electric telescopic rod 3, when the stamping die 6 is separated from the die limiting baffle 504 and loses the limiting thrust of the die limiting baffle 504, due to the resilience characteristics of the horizontal spring 406 and the longitudinal spring 407, the installation base 405 moves for reset, thereby driving the horizontal spring 406 to reset, and then waiting for the next stamping operation.
[0028] In summary, for this automatic deviation correction mechanism of the punching machine, through the coordinated operation of the components of this device, it solves the problems that in the actual use process of existing equipment, the material or the pressing die may have position deviations, resulting in unqualified quality of stamping products, and the high maintenance cost and low maintenance efficiency of electronic induction equipment in the damaged state.
