[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] like Figures 1-6 As shown, a punching device includes: a workbench 1, a clamping plate 14 and a base 17,
[0030] The servo motors 2 on both sides of the workbench 1 are fixedly connected, and a punching machine 3 is provided on the top of the workbench 1 and both sides are fixedly connected to the punching machine 3. A punch 10 is fixedly connected to the bottom end of the punching machine 3. There are two groups of clamping plates 14 and they are both connected to the workbench 1. The clamping plates 14 cooperate with the servo motor 2, and the fixture clamps the workpiece to move on the guide rail. When the workpiece moves to the top of the workbench 1, in order to avoid the mismatch between the die and the workpiece in the prior art, the die is removed from the top of the workbench 1, the servo motors 2 on both sides of the workbench 1 are operated, and the servo motor 2 drives the clamping plates 14 to move, and the clamping plates 14 clamp the two ends of the workpiece, and the punching machine 3 drives the punch 10 to operate, and the punch 10 punches the workpiece. No matter what shape the workpiece is, the clamping plates 14 can hold and limit the two ends of the workpiece to ensure that the workpiece will not deviate when punched by the punch 10, thereby improving the applicability of the punching machine 3.
[0031] The base 17 is connected to the workbench 1, and a guide hole 16 is opened longitudinally through the base 17. In order to avoid the phenomenon of no contact between the bottom end of the workpiece and the workbench 1, before the punch 10 punches the workpiece, the base 17 moves to the bottom end of the workpiece. The base 17 supports the workpiece to avoid the vertical deviation of the workpiece during punching, thereby ensuring the accuracy and quality of the punching of the workpiece. When waste chips are generated when the workpiece is punched, the waste chips fall along the guide hole 16, and the base 17 has the function of guiding the waste chips.
[0032] In some specific implementation schemes, slide grooves 12 are respectively provided on both sides of the workbench 1, and a lifting groove 15 is provided through the center of the workbench 1. The clamping plate 14 is slidably connected to the slide groove 12, and the inner wall of the lifting groove 15 is slidably connected to the base 17. The side end of the servo motor 2 is fixedly connected with a threaded rod 11, and the clamping plate 14 is provided with a threaded hole 13 along the axis of the threaded rod 11. The threaded rod 11 is threadedly connected to the threaded hole 13. When the clamping plate 14 needs to clamp the workpiece, the servo motor 2 runs, and the servo motor 2 drives the threaded rod 11 to rotate. The threaded rod 11 drives the clamping plate 14 to move through the threaded connection with the threaded hole 13, and the clamping plate 14 slides along the inner wall of the slide groove 12. When the clamping plate 14 resists the workpiece, the servo motor 2 stops running and the threaded rod 11 stops rotating. Among them, the slide groove 12 ensures the sliding stability of the clamping plate 14 by limiting the clamping plate 14.
[0033] In some specific embodiments, the bottom ends of the base 17 are fixedly connected to driving components on both sides, the bottom end of the driving component is fixedly connected to the bottom plate 4, a number of support columns 5 are provided between the bottom plate 4 and the workbench 1, the number of support columns 5 are located around the workbench 1 and the upper and lower ends are fixedly connected to the workbench 1 and the bottom plate 4 respectively, the driving component includes: a driving machine 20 and a lifting rod 19, the driving machine 20 is fixedly connected to the bottom plate 4, the lifting rod 19 is located between the base 17 and the driving machine 20 and the upper and lower ends are fixedly connected to the base 17 and the driving machine 20 respectively, when the clamping plate 14 clamps the workpiece When the workpiece is in contact with the base 17, the driving motor 20 drives the lifting rod 19 to move upward, and the lifting rod 19 supports the base 17 to move upward, and the base 17 slides along the inner wall of the lifting groove 15. When the base 17 and the workpiece are in contact, the driving motor 20 stops running. The distribution of the driving components ensures that both ends of the base 17 can be driven, thereby achieving the stability of the sliding of the base 17. The lifting groove 15 further limits the base 17 to avoid the base 17 from deviating. Among them, the support column 5 has a supporting function to prevent the driving motor 20 from being unable to adapt when installed at the bottom of the workbench 1.
[0034] In some specific embodiments, a plurality of guide grooves 9 are horizontally opened on the top of the bottom plate 4, and a storage box 6 is slidably connected to the top of the bottom plate 4. The storage box 6 cooperates with the base 17, and a plurality of guide columns 8 are fixedly connected to the bottom end of the storage box 6 along the width direction. A handle 7 is fixedly connected to the side end of the storage box 6. The guide column 8 is semi-cylindrical and slidably connected to the guide groove 9. When waste chips fall along the guide hole 16, the waste chips fall into the storage box 6, and the storage box 6 achieves the effect of collecting waste chips. When the waste chips in the box 6 are fully collected, the staff controls the handle 7 to pull the storage box 6 to clean the waste chips in the storage box 6 to prevent the waste chips from falling directly onto the bottom plate 4 and polluting the environment. Among them, the guide column 8 slides along the guide groove 9. The guide column 8 can position the storage box 6 to ensure that the storage box 6 collects the waste chips at the bottom end of the base 17. At the same time, the guide column 8 limits the storage box 6 by limiting the connection with the guide groove 9 to prevent the storage box 6 from offsetting on the bottom plate 4.
[0035] In some specific embodiments, a rounded corner 18 is provided on the inner wall of the top of the guide hole 16. The rounded corner 18 provided on the inner wall of the guide hole 16 increases the area of the guide hole 16 for collecting waste chips. At the same time, the rounded corner 18 makes it easier for waste chips to fall into the guide hole 16, thereby improving the effect of the guide hole 16 in guiding waste chips.
[0036] The above describes several embodiments of the present invention in detail, but the present invention is not limited to these embodiments and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
