Description

Technical Field

[0001] The utility model relates to the technical field of engraving dies, and particularly relates to a high-precision engraving die. Background Art

[0002] A high-precision engraving die is a highly accurate die, also known as an engraving cutter die. It is mainly used to engrave fine patterns, characters, shapes or structures on metals, plastics, rubbers or other materials through high-precision processing techniques. The design and manufacture of this kind of die require extremely high precision and process level to ensure that the finally processed products can meet strict dimensional and shape requirements.

[0003] However, the blade depth of the existing engraving dies is usually fixed and cannot be adjusted according to actual processing needs during the die-cutting process. If the thickness, material or required cutting depth of the processing object changes, it may be necessary to replace the entire die, thus reducing the flexibility and efficiency of processing. For this reason, a high-precision engraving die is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the blade depth of the existing engraving dies is usually fixed and cannot be adjusted according to actual processing needs during the die-cutting process. The utility model provides a high-precision engraving die.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0006] A high-precision engraving die includes a die cutter body. The die cutter body is a rectangular box body with a hollow interior. A square ring groove is opened at the top of the die cutter body. A square frame with adjustable height is arranged inside the square ring groove. A top plate is fixedly installed at the top of the square frame. A number of transversely equidistantly distributed mounting holes are opened at the top of the top plate. A blade is arranged inside each mounting hole. A strip-shaped rod is fixedly installed on the inner bottom surface of the die cutter body. A lifting assembly for driving the upper blade to lift is arranged at the bottom of each blade. A clamping assembly for fixing the lifting height of the blade is arranged on one side of the die cutter body.

[0007] Furthermore, the lifting assembly includes a mounting rod. Mounting rods are fixedly installed at positions corresponding to each mounting hole on the side of the die cutter body away from the clamping assembly inside the die cutter body. Each mounting rod is movably connected with a threaded rod. Each threaded rod is threadedly connected with a U-shaped frame. Each U-shaped frame is fixedly connected with the upper blade. A bevel gear one is fixedly installed at the bottom end of each threaded rod. A connecting shaft is movably installed at a position corresponding to each bevel gear one on the strip-shaped rod. A bevel gear two is fixedly installed at one end of each connecting shaft away from the clamping assembly. Each bevel gear two is meshed and connected with the adjacent bevel gear one. A turntable is fixedly installed at one end of each connecting shaft away from the bevel gear two.

[0008] Further, the clamping assembly includes a cross bar. Two cross bars are arranged on one side of the die body. Arc-shaped blocks are fixedly installed on the side of the two cross bars close to each other corresponding to the position of each turntable. Two sliding grooves are formed on one side of the die body. A slider is movably installed inside each sliding groove. Each slider is fixedly connected to the upper cross bar. The lower cross bar is fixedly connected to the die body. Square blocks are fixedly installed at both ends of one side of each cross bar away from the die body. Bolts are commonly penetrated through every two adjacent square blocks. Nuts are threadedly connected to each bolt.

[0009] Further, positioning blocks are fixedly installed at the edges of the bottom of the top plate corresponding to each mounting hole. The top of each positioning block is in contact with the bottom of the upper blade.

[0010] Further, a plurality of equally spaced strip-shaped holes are formed on both side wall surfaces of the die body. A lead screw is arranged inside each strip-shaped hole. Each lead screw is fixedly connected to the square frame. Nuts are threadedly connected to each lead screw.

[0011] Further, the inner hollow cross-section of the sliding groove is an isosceles trapezoid structure, and the slider is adapted to the inner hollow area of the sliding groove.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. When the cutting depth of a certain blade of the present utility model is relatively shallow, the staff can adjust the corresponding lifting assembly below the blade, so that the blade moves away from the die body, and then fix each blade at the current adjusted position by adjusting the clamping assembly. The effect is that the staff can select and adjust the cutting depth of a certain blade according to the cutting requirements. When it is necessary to adjust the cutting depth of each blade at the same time, the staff can adjust the top plate to make the square frame approach or move away from the die body inside the square ring groove. When the square frame moves away from the die body inside the square ring groove, the exposed part of the blade is less, so the cutting depth is shallower. When the square frame approaches the die body inside the square ring groove, the exposed part of the blade is more, so the cutting depth is deeper. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Such asFigures 1 to 5 As shown in the figure, a high-precision engraving die includes a die body 1. The die body 1 is a rectangular box with a hollow interior. A square ring groove 2 is formed at the top of the die body 1. A square frame 3 with adjustable height is arranged inside the square ring groove 2. A top plate 4 is fixedly installed at the top of the square frame 3. A number of mounting holes 5 are arranged at equal intervals horizontally on the top of the top plate 4. A blade 6 is arranged inside each mounting hole 5. A strip-shaped rod 7 is fixedly installed on the inner bottom surface of the die body 1. A lifting component 8 for driving the upper blade 6 to lift and lower is arranged at the bottom of each blade 6. A clamping component 9 for fixing the lifting height of the blade 6 is arranged on one side of the die body 1. It should be noted that when the cutting depth of a certain blade 6 is relatively shallow, the staff can adjust the corresponding lifting component 8 below the blade 6, so that the blade 6 moves away from the die body 1, and then fix each blade 6 at the current adjusted position by adjusting the clamping component 9. The effect is that the staff can select and adjust the cutting depth of a certain blade 6 according to the cutting requirements. When it is necessary to adjust the cutting depth of each blade 6 at the same time, the staff can adjust the top plate 4 to make the square frame 3 approach or move away from the die body 1 inside the square ring groove 2. When the square frame 3 moves away from the die body 1 inside the square ring groove 2, the exposed part of the blade 6 is less, so the cutting depth is shallower. When the square frame 3 approaches the die body 1 inside the square ring groove 2, the exposed part of the blade 6 is more, so the cutting depth is deeper.

[0025] As Figures 1 to 3 shown in the figure, the lifting component 8 includes a mounting rod 801. Mounting rods 801 are fixedly installed at the positions corresponding to each mounting hole 5 on the side of the die body 1 away from the clamping component 9. A threaded rod 802 is movably connected to each mounting rod 801. A U-shaped frame 803 is threadedly connected to each threaded rod 802. Each U-shaped frame 803 is fixedly connected to the upper blade 6. A bevel gear one 804 is fixedly installed at the bottom end of each threaded rod 802. A connecting shaft 806 is movably installed at the position corresponding to each bevel gear one 804 on the strip-shaped rod 7. A bevel gear two 805 is fixedly installed at one end of each connecting shaft 806 away from the clamping component 9. Each bevel gear two 805 is meshed and connected with the adjacent bevel gear one 804. A turntable 807 is fixedly installed at one end of each connecting shaft 806 away from the bevel gear two 805. It should be noted that the staff rotates the turntable 807 to drive the corresponding connecting shaft 806 and bevel gear two 805 to rotate synchronously through the turntable 807. The rotation of the bevel gear two 805 will drive the bevel gear one 804 meshed and connected with it to rotate. The rotation of the bevel gear one 804 will drive the corresponding threaded rod 802 to rotate synchronously. The staff only needs to control the rotation direction of the turntable 807 to make the threaded rod 802 rotate reciprocally. The reciprocal rotation of the threaded rod 802 can make the corresponding U-shaped frame 803 lift and lower. The lifting and lowering of the U-shaped frame 803 can drive the corresponding blade 6 to lift and lower synchronously.

[0026] like Figure 2 , Figure 4 As shown, the clamping assembly 9 includes a cross bar 901, two cross bars 901 are arranged on one side of the die cutter body 1, and an arc block 902 is fixedly installed on the side of the two cross bars 901 close to each other corresponding to the position of each turntable 807, and two slide grooves 903 are arranged on one side of the die cutter body 1, and a slider 904 is movably installed inside each slide groove 903, each slider 904 is fixedly connected to the upper cross bar 901, and the lower cross bar 901 is fixedly connected to the die cutter body 1, and blocks 90 are fixedly installed at both ends of the side of each cross bar 901 away from the die cutter body 1. 5. A bolt 906 is provided through each two adjacent blocks 905. A nut 907 is threadedly connected to each bolt 906. It should be noted that by rotating each nut 907, each two adjacent blocks 905 are brought closer to each other, so that the upper cross bar 901 is fixedly connected to the lower cross bar 901. The upper cross bar 901 moves up and down to drive the two sliders 904 to slide in the slide groove 903 respectively. Each turntable 807 is clamped by the corresponding two arc blocks 902 to prevent the nut 907 from rotating to ensure the height of the blade 6 adjusted by the lifting assembly 8.

[0027] like Figure 3 As shown, a positioning block 10 is fixedly installed at the bottom of the top plate 4 corresponding to the edge of each mounting hole 5, and the top of each positioning block 10 is in contact with the bottom of the upper blade 6. It should be noted that the positioning block 10 can limit the downward position of the blade 6 to prevent the blade 6 from moving downward excessively.

[0028] like Figure 2 , Figure 5 As shown, the two side walls of the die body 1 are respectively provided with a plurality of equally spaced strip holes 11, each strip hole 11 is provided with a screw rod 12 inside, each screw rod 12 is fixedly connected to the square frame 3, and each screw rod 12 is threadedly connected with a nut 13. It should be noted that by moving the square frame 3 closer to or farther away from the die body 1 inside the square ring groove 2, the square frame 3 can drive the screw rod 12 connected to it to move synchronously, and after the position of the square frame 3 is adjusted, each nut 13 can be turned to fix the current position of the square frame 3.

[0029] like Figure 4 As shown, the internal hollow cross-section of the slide groove 903 is an isosceles trapezoidal structure, and the slider 904 is adapted to the internal hollow area of ​​the slide groove 903. It should be noted that the slide groove 903 and the slider 904 cooperate with each other to limit the moving trajectory of the upper cross bar 901. Since the slider 904 is adapted to the internal hollow area of ​​the slide groove 903, the slider 904 will not easily detach from the inside of the slide groove 903.

[0030] In summary:

[0031] When the cutting depth of a certain blade 6 is relatively shallow, the operator can adjust the corresponding lifting assembly 8 below the blade 6, so that the blade 6 moves away from the die body 1. Then, the operator can fix each blade 6 at the current adjusted position by adjusting the clamping assembly 9. The effect is that the operator can select and adjust the cutting depth of a certain blade 6 according to the cutting requirements. When it is necessary to adjust the cutting depth of each blade 6 simultaneously, the operator can adjust the top plate 4 to make the square frame 3 approach or move away from the die body 1 inside the square ring groove 2. When the square frame 3 moves away from the die body 1 inside the square ring groove 2, the exposed part of the blade 6 is less, so the cutting depth is shallower. When the square frame 3 approaches the die body 1 inside the square ring groove 2, the exposed part of the blade 6 is more, so the cutting depth is deeper.
