Detailed Description

The technical solution of the present invention will be described clearly and completely through the following detailed description. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 4, a die cutting tool includes an upper die 1 and a lower die 2, the upper die 1 and the lower die 2 are disposed in a vertical correspondence, and a protrusion 3 is disposed on a surface of the lower die 2, and correspondingly, a die cutting blade block 4 is disposed on the upper die 1 at a position corresponding to the protrusion 3, and a cutting end 10 is disposed at a bottom end of the die cutting blade block 4. When the material to be processed is cut by the die cutting equipment, the upper die 1 is close to the lower die 2, and a circular hole can be formed on the plate-shaped material to be processed by the die cutting knife block 4 on the upper die 1 to form waste materials. The protruding 3 structures that set up on the lower mould 2 for the process that the waste material drops from the round hole inboard is more convenient, and the process of cutting is more smooth.

The die cutting knife block 4 is detachably arranged on the upper die 1. The top of cross cutting cutter piece 4 is provided with a fixed part 5, goes up mould 1 and goes up the concave mounting groove 6 that is equipped with, and fixed part 5 imbeds in the mounting groove 6 and through set screw 7 fastening connection. The fixing portion 5 may be formed in a square plate shape, or the fixing portion 5 may also be formed in a circular plate shape, so that the die cutter block 4 can be fixed to the upper die 1 through the fixing portion 5. In this embodiment, the surface of the die-cutting blade block 4 is flush with the upper mold 1, so that the overall structure of the die-cutting blade is more beautiful.

When the die-cutter block 4 is mounted, the fixing part 5 of the die-cutter block 4 is placed in the mounting groove 6, and then the fixing part 5 is fixedly mounted in the mounting groove 6 of the upper die 1 by a plurality of fixing screws 7, thereby completing the mounting of the die-cutter block 4. Moreover, it is easy to understand that, because the die-cutting knife block 4 is detachably arranged on the upper die 1, when the diameter of the cut round hole needs to be adjusted, only the die-cutting knife block 4 needs to be replaced, so that the die-cutting knife does not need to be integrally replaced, and the adaptability of the upper die 1 is improved. Referring to fig. 2, the die cutter block 4 is in a cuboid structure, and when the die cutter block 4 is installed on the upper die 1, the die cutter block 4 in the cuboid structure can be positioned in the radial direction, so that the possibility that the die cutter block 4 rotates on the upper die 1 to affect the installation stability of the die cutter block 4 is reduced.

In order to solve the problem that the cutting waste needs to be cleaned frequently in the prior art, the die cutting tool provided in the embodiment is particularly provided with an extrusion channel 8 for extruding the waste and a waste discharge channel 9 for accommodating the waste, which are integrally formed in the die cutting tool block 4. Specifically, the inside of the die cutting knife block 4 is respectively provided with an extrusion channel 8 and a waste discharge channel 9 along the direction vertical to the lower die 2, and the two channels are arranged in a penetrating way. Meanwhile, the end of the extrusion channel 8, which is not connected with the waste discharge channel 9, is flush with the cutting end 10 of the die cutter block 4, so that the cut waste materials can directly enter the extrusion channel 8 from the cutting end 10. The end of the waste discharge channel 9 which is not connected with the extrusion channel 8 is positioned on the top surface of the die cutter block 4, so that waste materials stored in the waste discharge channel 9 can be directly cleaned from the top surface of the die cutter block 4 at the later stage.

In order to realize that the waste material can be extruded in extrusion passageway 8 and take place deformation, the projection area of extrusion passageway 8 on lower mould 2 is designed into and is reduced gradually along the direction of keeping away from cutting end 10 promptly and the cross-section of extrusion passageway 8 is positive conical cylinder shape, along with once more cut the waste material that forms and get into extrusion passageway 8 again, the waste material that is located the superiors is by jack-up gradually and is removed to the channel 9 direction of wasting discharge, thereby reduce gradually along with the projection area of extrusion passageway 8 and make waste material extrusion deformation. Preferably, the vertical projection of the extrusion channel 8 on the lower die 2 is elliptical, so that the extrusion of the extrusion channel 8 on the waste is more stable, the ratio of the length of the long axis to the length of the short axis of the vertical projection on the lower die 2 is s, and s is greater than or equal to 1.1 and less than or equal to 1.2, so that the waste can stably move into the waste discharge channel 9 through the inner side of the extrusion channel 8.

The vertical projection of the waste discharge channel 9 on the lower die 2 is circular, and the projection area of the waste discharge channel 9 on the lower die 2 is gradually increased along the direction far away from the cutting end 10, namely, the section of the waste discharge channel 9 is in an inverted cone cylinder shape, so that more waste materials can be stored through the waste discharge channel 9. Meanwhile, the projection area of the end face of the waste discharge channel 9 close to the cutting end 10 on the lower die 2 is smaller than the projection area of the end face of the extrusion channel 8 far away from the cutting end 10 on the lower die 2, so that waste materials can fall on the end face of the extrusion channel 8 at the top of the waste discharge channel 9 after entering the waste discharge channel 9, and the possibility that the waste materials fall into the inner side of the extrusion channel 8 from the waste discharge channel 9 is reduced.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
