[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] It should be noted that in the description of this invention, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] like Figure 1-4As shown, the present invention provides an adjustable tool assembly, which includes a tool and a housing 5 for mounting the tool. The tool includes a tool holder 1 and a plurality of blades 2 mounted on the tool holder 1. The surface of the housing 5 is recessed downward to form a mounting portion 6 for mounting the tool holder 1. The housing 5 has a plurality of transverse screw holes 8 and at least one longitudinal screw hole 9. The transverse screw holes 8 penetrate from the upper surface of the housing 5 to the mounting portion 6, and the longitudinal screw hole 9 penetrates from one side of the housing 5 to the mounting portion 6. Transverse shims and longitudinal shims can be installed in the mounting portion 6. A transverse shim is installed below the mounting part 6, and a longitudinal shim is installed in the mounting part 6 opposite to the longitudinal screw hole 9. After the tool holder 1 is installed in the mounting part 6, the transverse and longitudinal shims are used to adjust the position of the tool in the housing 5. A transverse screw and a longitudinal screw are installed in the transverse screw hole 8 and the longitudinal screw hole 9, respectively. After the transverse screw passes through the transverse screw hole 8 and is tightened, the end of the transverse screw abuts against the upper surface of the tool holder 1. After the longitudinal screw passes through the longitudinal screw hole 9 and is tightened, the end of the longitudinal screw abuts against the outer wall of the tool holder 1. A shim can be installed at the bottom of the mounting hole 131 to adjust the height of the blade 2. The transverse and longitudinal shims are made of stainless steel. The bottom of the tool holder 1 has retaining strips 4 at both the top and bottom. The bottom of the mounting part 6 extends upward and downward to form a retaining groove 7 that matches the retaining strips 4. When the tool holder 1 is installed in the mounting part 6, the retaining strips 4 are engaged in the retaining groove 7.

[0030] This invention provides an adjustable cutter assembly capable of accommodating workpieces of different sizes, shapes, and materials, as the operator can easily adjust the cutter position as needed. This makes it more versatile and suitable for a variety of production requirements. The adjustability of the cutter position means that the operator can fine-tune cutting parameters to achieve higher cutting accuracy. This is particularly important for applications requiring high-precision cutting, such as electronic component manufacturing or the production of precision mechanical parts. By adjusting the cutter position, the cutting process can be controlled more accurately, reducing scrap rates. This saves material costs and labor, and improves production efficiency. Die-cutting machines with adjustable cutter positions typically achieve higher production efficiency due to better control over cutting parameters and adaptation to different workpieces. This helps reduce production costs and increase output.

[0031] like Figure 5-9As shown, this application also provides a die-cutting machine. The die-cutting machine includes a cutting tool assembly, an upper die holder, and a lower die holder. The cutting tool assembly is installed on the lower surface of the upper die holder. The die-cutting machine also includes a limiting mold frame. The limiting mold frame includes a locking template 11 for installation on the lower side of the upper die holder, a middle plate 12 for installation on the lower side of the locking template, and a universal limiting template 13 for installation on the lower side of the middle plate 12. The lower surface of the middle plate 12 has multiple inner holes. The universal limiting template 13 has multiple mounting holes 131. The mounting holes 131 correspond one-to-one with the inner holes. The mounting holes 131 are used to insert positioning pins 14. The lower surface of the universal limiting template 13 is used to install the cutting tool assembly. The outer shell 5 of the cutting tool assembly has a limiting hole. The positioning pin 14 passes through the limiting hole and is inserted into the mounting hole 131 to position the cutting tool holder 1 on the lower surface of the universal limiting template 13. When it is necessary to replace the die-cutting blade, simply pull out the positioning pin 14, remove the die-cutting blade from the universal limiting template 13, and then attach the new die-cutting blade to the universal limiting template 13 and fix it with the positioning pin 14. Disassembly and installation are very convenient.

[0032] The mounting holes 131 are arranged in an array on the limiting template, and the inner holes are arranged in an array on the middle plate 12. The mounting holes 131 have a square cross-section, and the portion of the positioning pin 14 inserted into the mounting hole 131 is square and matches the shape of the mounting hole 131. The square hole structure prevents the positioning pin 14 from rotating, making the positioning more accurate. A spring 17 is provided in the inner hole. When the positioning pin 14 retracts into the inner hole under external force, the spring 17 applies a downward rebound force to the positioning pin 14. This structure can prevent damage to the positioning pin 14 during the pressing process when it is not aligned with the clearance hole. Limiting platforms 132 are also provided at both ends of the lower surface of the limiting template. The limiting platforms 132 protrude relative to the lower surface of the universal limiting template 13. The limiting platforms 132 are used to limit the pressing height of the upper mold base, preventing excessive pressing or insufficient pressing height of the die-cutting blade. Because of the limiting platform 132, there is no need to adjust the pressing height of the upper mold base, thus improving production efficiency. A second strong magnet 134 is provided on the universal limiting template 13. The tool assembly is installed on the lower surface of the universal limiting template 13 by magnetic attraction. The locking template 11 is locked to the upper mold base, to the middle plate 12, and to the limiting template by screws.

[0033] The limiting mold frame also includes a lower template 16 disposed on the upper side of the lower mold base and a clearance plate 15 mounted on the upper side of the lower template 16. The lower template 16 has multiple lower clearance holes 161, and the clearance plate 15 has multiple upper clearance holes 151. The upper clearance holes 151 are aligned with the lower clearance holes 161. The lower template 16 is also provided with multiple first strong magnetic blocks 162. The clearance plate 15 is mounted on the lower template 16 by magnetic attraction. The upper surface of the lower template 16 is provided with multiple pins 163. The edge of the relief plate 15 is recessed inward to form a groove 152. The position of the pin 163 corresponds to the position of the groove 152. When the relief plate 15 is installed on the lower template 16, the pin 163 is inserted into the groove 152. The upper surface of the lower template 16 is also provided with two downward recessed portions 164. When the relief plate 15 is installed on the lower template 16, the edge of the relief plate 15 is located above the recessed portions 164 and partially covers the recessed portions 164.

[0034] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
