[0018] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0019] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0020] like Figure 1As shown, the utility model provides a universal sleeve jig for fast die change of flat knife, comprising a jig pad 1 and a plurality of movable clamping positions 2, the flat knife die is fixedly mounted on the jig pad 1, and is used for die-cutting and punching a material strip thereon, the clamping positions 2 are movably arranged on the jig pad 1, and are used for pressing the material strip onto the blade of the flat knife die, so as to prevent the material strip from being separated from the blade of the flat knife die due to adhesion during the die-cutting process. It should be noted here that the existing jig is a set of jigs with a set of cutting dies. When it is necessary to use cutting dies with different jump distances for die cutting, not only the cutting dies need to be replaced, but also the jig needs to be replaced, and the machinist needs to cut out the pressing material position to fit it on the jig, resulting in high mold opening costs, complex mold changing procedures, and long mold changing time. In order to save jig costs and production line adjustment time, the present application provides a number of blanking grooves 12 at intervals on both sides of the jig pad 1. The opening position of the blanking groove 12 is consistent with the punching position of the material strip. When in use, the blade of the flat knife die is aligned with the corresponding blanking groove 12 is aligned. When the material strip passes through the blade of the flat knife die, the die-cutting waste falls into the corresponding blanking groove 12, and the die-cutting completed material strip can be transported to the next process. Since there are many blanking grooves 12 arranged continuously and the intervals are very small, it can be suitable for die cutters with different jump distances. When the die cutter jump distance is small, the blade of the die cutter can be aligned with the adjacent blanking grooves 12. When the die cutter jump distance is large, the blade of the die cutter can be aligned with the spaced blanking grooves 12 without replacing the jig, so that a pair of jigs can be used for molds with different jump distances, reducing jig costs and production adjustment time. Specifically, the jig pad 1 is in the shape of a long plate, and slots 11 are opened in parallel on both sides of its upper surface. A plurality of blanking grooves 12 are opened at intervals on the inner side of the slots 11. A through hole 121 is opened through the bottom of the blanking groove 12, and the die-cutting waste is discharged from the through hole 121.
[0021] Furthermore, in order to facilitate the replacement of the flat knife die and save the time of the mechanic to adjust the machine, the jig of the present application is also equipped with a number of movable clamping positions 2. When in use, the clamping position 2 can be moved to the corresponding cutting edge of the flat knife die, without the need for the mechanic to cut out the material pressing clamping position and stick it on the jig. Specifically, the clamping position 2 includes a card 21 and a clamping block 22. The card 21 is located above the jig pad 1 and is used to press the material strip onto the cutting edge of the flat knife die. It includes a first end and a second end. The clamping block 22 is vertically arranged below the first end of the card 21 and can be inserted into the card slot 11 so that the clamping position 2 can be horizontally displaced relative to the card slot 11. The end of the second end of the card 21 is provided with a U-shaped hole 211, and the U-shaped hole 211 is arranged corresponding to the blanking groove 12. When in use, align the cutting edge of the flat knife die with the blanking groove 12, and then move the clamping position 12 to the cutting edge of the flat knife die, and the material strip is located between the flat knife die and the clamping position 12. Preferably, the cross-section of the card slot 11 is rectangular, and the bottom of the card block 22 can be inserted into the card slot 11 and abut against the two side groove surfaces of the card slot 11 to ensure that the card block 22 is horizontally displaced along the card slot 11 to prevent the card block 22 from rotating and shaking in the card slot 11.
[0022] Preferably, the height of the card block 22 is higher than the depth of the card slot 11, so that the card 21 is attached to the top of the flat knife die, and the bottom of the second end of the card 21 is milled thinner than the bottom of the first end for carrying the material tape. Specifically, if the thickness of the material tape is 0.85 mm, the bottom of the second end of the card 21 is milled thinner by 0.85 mm for pressing the material tape onto the edge of the flat knife die to prevent the material tape from detaching from the flat knife die due to adhesion during the die-cutting process.
[0023] Furthermore, a plurality of first screw holes are spaced apart at the bottom of the slot 11 , and a second screw hole is penetrated through the middle of the block 22 , so that the block 22 can be fixedly installed in the slot 11 by means of the bolts 3 .
[0024] Furthermore, the first screw hole is arranged corresponding to the blanking groove 12 , and when the clamping block 22 is fixedly installed in the clamping groove 11 by means of bolts, the U-shaped hole 211 is located above the blanking groove 12 .
[0025] When in use, the flat knife die is fixedly installed on the jig pad so that the cutting edge of the flat knife die is aligned with the blanking slot of the jig pad, and then the material strip is placed on top of the flat knife die, the card block is fixed to the card slot by bolts, and the U-shaped hole of the card is located at the cutting edge of the flat knife die.
[0026] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
