Description

Technical Field

[0001] The invention relates to the technical field of die-cutting equipment, in particular to a cutting die with a limiting device. Background Art

[0002] Existing die-cutting operations, especially for the punching of micron-level films, require the stamping equipment to have precise Z-axis accuracy. Figure 1 It is an existing conventional cutting equipment, which fixes a cutting die on the lower area of ​​the platform on the equipment, and uses the lower convex blade of the cutting die to punch out the corresponding shape of the upper film on the surface with at least two layers of film. In the actual process, the platform on the equipment drives the cutting die to punch downward, and its Z-axis accuracy requires reliable control of the driving power source corresponding to the platform on the equipment. At the micron level, the driving power source cannot use servo-type precision power equipment in order to pursue reliable downward force, which leads to the inability of the driving power source on the platform on the equipment in the prior art to accurately control the Z-axis accuracy, which leads to the cutting thickness of the cutting die being greater than the preset thickness, and even the blade of the cutting die directly punches to the lower plane of the equipment, so that the die-cutting product cannot meet the product appearance requirements and the cutting die is often damaged. Summary of the invention

[0003] In response to the above problems, the present invention provides a cutting die with a limiting device, so that the cutting die can ensure the cutting depth of the blade during cutting, ensure that the blade will not cut into the lower platform of the equipment, ensure that the die-cut product meets the product appearance requirements, and protect the cutting die.

[0004] A cutting die with a limiting device, characterized in that it comprises:

[0005] Die holder body;

[0006] Blade part;

[0007] and a peripheral limiting mechanism;

[0008] The blade part is located in the central area of ​​the lower surface of the die base body, and the outer periphery of the lower surface of the die base body is provided with a downwardly convex peripheral limiting mechanism, the bottom surface of the peripheral limiting mechanism is convex below the tip position of the blade part, and the downward convex distance D of the bottom surface of the peripheral limiting mechanism relative to the tip position of the blade part is the thickness of the lower film layer of the corresponding die-cutting product.

[0013] The outer peripheral position of the lower surface of the die holder is provided with an inner concave mounting groove, and the inner concave mounting groove is also provided with a locking threaded hole in the thickness direction. The outer limiting mechanism includes a top locking block and a lower limiting block. The top locking block is reliably locked in the inner concave mounting groove by bolts, so that the lower convex distance D can be quickly adjusted according to the thickness of the lower film layer of the die-cut product;

[0014] The lower platform of the device is provided with an inner concave storage groove corresponding to the corresponding position of the lower limit block, and a hard plastic pad is embedded in the inner concave storage groove, and the surface area of ​​the hard plastic pad covers the bottom surface area of ​​the lower limit block at the corresponding position, which reduces the hard impact received by the lower platform of the device during punching;

[0015] After the hard plastic pad is embedded in place, the upper surface of the hard plastic pad is flush with the surface of the lower platform of the equipment;

[0016] When the hard plastic pad is deformed or partially worn, the hard plastic pad can be quickly replaced to ensure the long-term stable and reliable use of the die cutter and reduce the cost of consumable parts of the die cutting equipment;

The top locking block is provided with a plurality of through locking holes at the surface boundary corresponding to the lower limit block. The upper surface of the lower limit block is provided with a plurality of locking threads. The locking bolts penetrate the through locking holes and are fixed to the locking threads.

[0019] Preferably, it also includes an adjusting metal layer, which is a thin metal sheet. The shape of the adjusting metal layer is made to imitate the top view of the lower limit block. Corresponding guide through holes are arranged around the adjusting metal layer. When the surface of the lower limit block is worn, the surface is reliably ground by an external grinder, and then the adjusting metal layer is arranged between the top locking block and the lower limit block. The number of the adjusting metal layers is specifically arranged according to the actual thickness after grinding.

DETAILED DESCRIPTION

[0027] A knife die with a limiting device, see Figure 2-Figure 4 , which includes a die base body 10, a blade portion 20, and a peripheral limiting mechanism 30;

[0028] During assembly, it also includes an upper device platform 40 and a lower device platform 50. A multi-mode product is arranged on the lower device platform. During specific implementation, the multi-mode product is a dual-mode product 60. The dual-mode product includes an upper film layer 61 and a lower film layer 62.

[0029] The blade portion 20 is located in the central area of ​​the lower surface of the die base body 10. A downwardly convex peripheral limiting mechanism 30 is provided on the periphery of the lower surface of the die base body 10. The bottom surface of the peripheral limiting mechanism 30 is convex below the tip position 21 of the blade portion 20. The downward convex distance D of the bottom surface of the peripheral limiting mechanism 30 relative to the tip position 21 of the blade portion 20 is the thickness of the lower film layer 62 of the corresponding die-cutting product.

[0030] In a specific implementation, the shape of the die holder 10 in a top view includes a circle or a rectangle, which is set according to the die-cutting shape and the shape of the blade portion 20 .

[0031] In a specific embodiment, the lower surface of the die holder body 10 is provided with independently arranged peripheral limiting mechanisms 30 only on two side edges thereof;

[0032] The outer circumference of both sides of the lower surface of the die holder 10 is respectively provided with inner concave mounting grooves 11, and the inner concave mounting grooves 11 are also provided with locking threaded holes 12 in the thickness direction. The outer limiting mechanism 30 includes a top locking block 31 and a lower limiting block 32. The top locking block 32 is reliably locked in the inner concave mounting groove 11 by bolts 70, so that the lower convex distance D can be quickly adjusted according to the thickness of the lower film layer 62 of the die-cut product.

[0033] The lower platform 50 of the device is provided with an inner concave storage groove 51 at a position corresponding to the lower limit block 32, and a hard plastic pad 80 is embedded in the inner concave storage groove 51. The surface area of ​​the hard plastic pad 80 covers the bottom surface area of ​​the lower limit block 32 at the corresponding position, which reduces the hard impact received by the lower platform 50 of the device during punching;

[0034] After the hard plastic pad 80 is inserted into place, the upper surface of the hard plastic pad 80 is flush with the surface of the lower platform 50 of the equipment;

[0035] When the hard plastic pad 80 has surface deformation or partial wear, the hard plastic pad 80 can be quickly replaced to ensure long-term stable and reliable use of the die cutting die and reduce the cost of consumable parts of the die cutting equipment.

[0036] In specific implementation, the top locking block 31 and the lower limit block 32 are split assembly structures. The top locking block 31 is provided with a plurality of penetrating locking holes 311 at the surface boundary corresponding to the lower limit block 32, and the upper surface of the lower limit block 32 is provided with a plurality of locking threads 321. The locking bolts 90 penetrate the locking holes 311 and are fixedly connected to the locking threads 321. When the lower limit block 32 is worn, it can be quickly replaced to further reduce the equipment cost.

[0037] In a preferred embodiment, the locking hole 311 is a stepped hole, the upper layer of the stepped hole is a countersunk groove, and the head of the locking bolt 90 is located in the countersunk groove of the stepped hole, ensuring the reliable installation of the top locking block 31 and the lower limit block 32;

[0038] It also includes an adjusting metal layer 33, which is a thin metal sheet. The shape of the adjusting metal layer 33 is made to imitate the top view of the lower limit block 32. Corresponding guide through holes 331 are arranged around the adjusting metal layer 33. When the surface of the lower limit block 32 is worn, the surface is reliably ground by an external grinder, and then the adjusting metal layer 33 is set between the top locking block 31 and the lower limit block 32. The number of adjusting metal layers 33 is specifically arranged according to the actual thickness after grinding.

[0039] Its working principle is as follows: a peripheral limiting mechanism is set in the peripheral area of ​​the blade part of the cutting die base body, so that the cutting die itself has a peripheral limiting mechanism for limiting the blade part, and the downward convex distance D of the bottom surface of the peripheral limiting mechanism relative to the tip position of the cutting edge part corresponds to the thickness of the lower film layer of the die-cutting product, so that the driving power source can directly drive the cutting die to the lowest position, so that the cutting die can ensure the cutting depth of the blade during cutting, ensure that the blade will not cut to the lower platform of the equipment, ensure that the die-cutting product meets the product appearance requirements, and protect the cutting die.
