[0019] like Figure 1-Figure 2 As shown, a chopping-type knife die assembly for honeycomb hole printed parts includes an upper knife die 1 and a lower knife die 2, and is characterized in that: a plurality of groups of indentation steel wires 21 corresponding to the honeycomb holes are arranged on the lower knife die 2, and the upper knife die 1 includes a bottom plate 11 and a knife seat 12 arranged on the bottom plate 11, and a plurality of closed-loop knife strips 13 corresponding to the indentation steel wires 21 are arranged on the knife seat 12; wherein, the cross-section of the closed-loop knife strip 13 is an unequal-sided triangle, and the inclination of the outer side is greater than the inclination of the inner side, which can effectively ensure a smooth incision and reduce deformation of the sheet, and at the same time can prevent the sheet from getting stuck at the closed-loop knife strip 13.

[0020] Specifically, the upper cutting die 1 and the lower cutting die 2 are respectively installed on the stamping equipment, and the honeycomb hole printed sheet is placed on the lower cutting die 2. The lower cutting die 2 is driven by the stamping equipment to press down on the raw material of the honeycomb hole printed part, and the indentation steel wire 21 on the lower cutting die 2 and the closed-loop knife strip 13 on the upper cutting die 1 are used to cut it into a shape.

[0021] The above, such as Figure 1 As shown, the closed-loop blade 13 includes a front surface A1301 located on the outside and a front surface B1302 located on the inside. A blade 1303 is formed at the intersection of the front surface A1301 and the front surface B1302. The flatness of the blade 1303 is 0.02 mm to 0.03 mm to improve the sharpness of the blade 1303.

[0022] The above, such as Figure 1As shown, the angle between the front A1301 and the bottom side of the closed-loop blade 13 is 80°~89°, and the angle between the front B1302 and the bottom side of the closed-loop blade 13 is 50°~59°. Preferably, the best effect is achieved when the angle between the front A1301 and the bottom side of the closed-loop blade 13 is 85° and the angle between the front B1302 and the bottom side of the closed-loop blade 13 is 55°.

[0023] In the present embodiment, the thickness of the sheet used for the honeycomb hole printed parts is mostly 0.03mm, the height of the closed-loop blade 13 is 1.0mm~1.5mm, and the instantaneous compression amount of the chopping knife die assembly at each chopping is consistent with the height of the closed-loop blade 13, and the height of the closed-loop blade 13 is 1.0mm~1.5mm, which can ensure that the honeycomb hole printed part sheet is completely chopped and at the same time can also ensure the strength of the closed-loop blade 13.

[0024] The lower die 2 is provided with a foam sponge to reduce the rebound and noise of the rubber plate on the stamping equipment when it is pressed down, and to avoid excessive vibration caused by the upper die 1 pressing down and affecting the die-cutting quality. At the same time, the use of the foam sponge can also effectively reduce the pressure and impact force of the rubber plate, and avoid unnecessary noise and vibration.

[0025] As mentioned above, the lower cutting die 2 is provided with a positioning hole 22, so as to facilitate accurate fixing of the lower cutting die 2 on the working platform of the stamping equipment by fasteners such as latches.

[0026] As mentioned above, the base plate 11 and the knife seat 12 can be detachably connected by bolts, so as to facilitate disassembly and replacement.

[0027] Working principle: The upper die 1 and the lower die 2 are respectively installed on the stamping equipment, and the honeycomb hole printed sheet is placed on the lower die 2. The stamping equipment drives the lower die 2 to press down on the raw material of the honeycomb hole printed, and the indentation steel wire 21 on the lower die 2 and the closed-loop blade 13 on the upper die 1 are used to cut and punch it. The closed-loop blade 13, which has an unequal-sided triangle cross section and a greater outer inclination than its inner inclination, can effectively ensure a smooth cut and reduce sheet deformation, and can also prevent the sheet from getting stuck at the closed-loop blade 13.

[0028] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
