Description

Technical Field

[0001] The utility model relates to the field of plate stamping, in particular to a plate stamping device. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size.

[0003] However, the stamping of some plates requires stamping operations at multiple locations of the plate as needed. Most existing stamping equipment can only perform stamping operations on one part of the plate. When stamping is required at another location of the plate, the plate needs to be moved to another corresponding stamping equipment or a new mold needs to be replaced and the mold position needs to be adjusted before the operation can be carried out. This will result in higher costs for the stamping operation. Utility Model Content

A slide is threadedly connected to the outer periphery of the second motor, and the slide is slidably connected to the operating table. A third motor is installed in the middle of the slide. A rotating plate is fixed to the output end of the third motor. A support ring is provided on the outer ring of the third motor, and the support ring is fixed to the slide. A supporting plate is fixed to the upper end of the rotating plate by bolts. Square holes are opened on both sides of the front and rear ends of the supporting plate, and limit blocks are fixed at the four corners of the supporting plate.

[0008] Preferably, the uppermost ends of the bolts for fixing the bearing plate and the rotating plate are flush with the upper end surface of the bearing plate.

[0009] Preferably, the size of the slide plate is larger than that of the bearing plate, and the outer ring of the slide plate is provided with convex strips.

[0010] Preferably: the operating mechanism includes a raising frame, which is fixed to the upper end of the operating table, the internal rotation of the top plate of the raising frame is connected to the first screw, the input end of the first screw is installed with a first motor, the outer periphery of the first screw is threadedly connected to a slider, a hydraulic cylinder is installed in the middle of the slider, and a loading plate is fixed to the telescopic end of the hydraulic cylinder.

[0011] Preferably: the lower end of the loading plate is fixed with a lower pressure plate by bolts, a ring knife is fixed in the middle of the lower pressure plate, a groove stamping column is provided on one side of the ring knife, and the groove stamping column is fixed to the lower pressure plate, dampers are installed on the front and rear sides of the lower end of the lower pressure plate, and a protective plate is fixed to the lower end of the damper.

A protective plate 210 is fixed to the lower end of the damper 29, and the protective plate 210 is provided with through holes corresponding to the positions of the ring knife 27 and the groove stamping column 28; through the threaded connection between the first screw 21 and the slider 23 and the sliding connection between the slider 23 and the pad frame 2, when the first motor 22 drives the first screw 21 to rotate, the position of the slider 23 can be adjusted, thereby adjusting the stamping position.

[0028] The loading mechanism includes a second screw rod 3, which is rotatably connected to the inside of the operating table 1, a second motor 31 is installed on the input end of the second screw rod 3, and a slide plate 32 is threadedly connected to the outer periphery of the second motor 31, and the slide plate 32 is slidably connected to the operating table 1, and a third motor 33 is installed in the middle of the slide plate 32, and a rotating plate 34 is fixed to the output end of the third motor 33, and a support ring 35 is provided on the outer ring of the third motor 33, and the support ring 35 is fixed to the slide plate 32, and the upper end of the rotating plate 34 is fixed with a supporting plate 36 by bolts, and the upper end of the bolts for fixing the supporting plate 36 to the rotating plate 34 is flush with the upper end surface of the supporting plate 36, the size of the slide plate 32 is larger than the supporting plate 36, and the outer ring of the slide plate 32 is provided with a convex strip, square holes 37 are provided on both sides of the front and rear ends of the supporting plate 36, and limit blocks 38 are fixed at the four corners of the supporting plate 36; when the device performs stamping processing on the plate, the plate to be processed is first placed in the middle of the supporting plate 36, and through four The limit block 38 limits the plate, and then through the threaded connection between the second screw 3 and the slide plate 32 and the sliding connection between the slide plate 32 and the operating table 1, when the second motor 31 drives the second screw 3 to rotate, the slide plate 32 can be moved back and forth, so that one corner of the plate on the supporting plate 36 is located at the lower end of the operating mechanism. After the operating mechanism processes this corner, the third motor 33 drives the supporting plate 36 at the upper end of the rotating plate 34 to rotate, so that the other corner of the plate is located at the lower end of the operating mechanism, and then the four corners of the plate are punched in turn. By combining this with the punching position of the operating mechanism, it can be adjusted as needed, so that the device can punch multiple positions of the plate at one time, and because the size of the slide plate 32 is larger than the supporting plate 36 and the square hole 37 is set, the waste generated during the punching operation can be collected by the slide plate 32, thereby preventing the waste generated by the punching from affecting the driving structure of the device.

[0030] Working principle: When the device is punching the plate, the plate to be processed is first placed in the middle of the supporting plate 36, and the plate is limited by four limit blocks 38. Then, through the threaded connection between the second screw 3 and the slide 32 and the sliding connection between the slide 32 and the operating table 1, when the second motor 31 drives the second screw 3 to rotate, the slide 32 can be moved back and forth, so that one corner of the plate on the supporting plate 36 is located directly below the protective plate 210, and then the hydraulic cylinder 24 drives the lower pressure plate 26 to descend, so that the ring knife 27 and the groove punching column 28 punch a corner of the sheet material. After this corner is processed, the third motor 33 drives the supporting plate 36 at the upper end of the rotating plate 34 to rotate, so that the other corner of the plate is located directly below the operating mechanism. Then, the four corners of the plate are punched in turn. Since the size of the slide plate 32 is larger than the supporting plate 36 and the square hole 37, the waste generated during the stamping operation can be collected by the slide plate 32, thereby preventing the waste generated by the stamping from affecting the driving structure of the device. Moreover, since the lower pressure plate 26 and the loading plate 25 are fixed by bolts and the supporting plate 36 and the rotating plate 34 are fixed by bolts, the bolts can be unscrewed and replaced with other types of stamping dies and loading structures. Then, through the threaded connection between the slider 23 and the first screw 21 and the sliding connection between the slider 23 and the pad frame 2, when the first motor 22 drives the first screw 21 to rotate, the slider 23 can drive the stamping structure to move, thereby adjusting the stamping position. In this way, the applicability of the device can be improved.
