[0029] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] Reference Figures 1-7 A high-wear-resistant cutting die with ultra-deep cryogenic treatment includes: a top plate 100; a cutting head 200, which is installed at the bottom of the top plate 100 via a connector 103; an outer pressing plate 300 disposed below the top plate 100; and an inner pressing plate 400 disposed below the top plate 100, with the cutting head 200 disposed between the outer pressing plate 300 and the inner pressing plate 400.

[0032] In this embodiment, the outer pressing plate 300 and the inner pressing plate 400 are obtained by cutting and separating a single plate. During the assembly of the cutting die, the cutting head 200 is first installed on the top plate 100, and then a single plate is installed below the top plate 100, with the plate having the same dimensions as the top plate 100. Bolts are used to fix the plate to the moving block 301 and the moving plate 402. The top plate 100 is connected to the output shaft of the cutting machine, which drives the top plate 100 downwards. The plate stops moving when it contacts the cutting table, and the cutting head 200 continues to move downwards following the top plate 100. At this point, the cutting head 200 cuts the entire plate to form the outer pressing plate 300. The outer pressing plate 300 and the inner pressing plate 400 are two plates, and the shapes of the outer pressing plate 300 and the inner pressing plate 400 can also be adapted to the shape of the current cutting head 200. The outer pressing plate 300 is connected by several moving blocks 301, and the inner pressing plate 400 is connected by moving plates 402. Then, a true length cutting operation can be performed. After the material is placed on the cutting table, the outer pressing plate 300 and the inner pressing plate 400 first press and fix the material. The cutting head 200 passes between the outer pressing plate 300 and the inner pressing plate 400 and cuts the material. When the cutting head 200 is reset after cutting, the outer pressing plate 300 and the inner pressing plate 400 can press and fix the cut material on the cutting table.

[0033] The aforementioned tool tip 200 is made of Cr12MO1V steel, which possesses excellent toughness, wear resistance, and dimensional stability. After austenitization at 1060℃, high-hardness acicular martensite, finely dispersed granular carbides, and a certain amount of retained austenite are obtained. Subsequent ultra-deep cryogenic treatment at approximately -90℃ promotes the transformation of retained austenite into martensite and increases carbide precipitation, further enhancing the tool's wear resistance and dimensional stability. After quenching and ultra-deep cryogenic composite treatment, the hardness reaches 63-65 HRC. The metallographic structure consists of finely dispersed carbides and acicular martensite. Compared to conventional quenching and tempering processes, the hardness of tool tip 200 is increased by 3-5 HRC, effectively improving wear resistance. The service life of tool tip 200 is also extended, significantly reducing costs and improving work efficiency.

[0034] Reference Figure 2 and Figure 6 The outer pressing plate 300 includes: several movable blocks 301, the bottom ends of which are connected to the top of the outer pressing plate 300; a groove 102 is provided at the bottom of the top plate 100, the number of which is several; the movable blocks 301 are connected in the groove 102; and several first elastic elements 302, which are respectively connected to the inner walls of the grooves 102, and one end of each first elastic element 302 is respectively connected to the movable blocks 301.

[0035] When the aforementioned movable block 301 is squeezed, it moves within the groove 102. The movable block 301 squeezes the first elastic element 302, and the first elastic element 302 can drive the movable block 301 to reset. The first elastic element 302 can be a spring or a spring block.

[0036] Reference Figure 2 and Figure 7 The inner pressing plate 400 includes: a fixed plate 401 disposed between the inner pressing plate 400 and the top plate 100, the top of the fixed plate 401 being installed at the bottom of the top plate 100; a movable plate 402 installed at the top of the inner pressing plate 400, the movable plate 402 being connected to the fixed plate 401; the inner pressing plate 400 further includes: a movable groove formed at the bottom of the fixed plate 401, the movable plate 402 being connected in the movable groove; and a second elastic member 403, one end of which is connected to the inner wall of the movable groove, and the other end of which is connected to the top of the movable plate 402.

[0037] When the aforementioned movable plate 402 is compressed, it can move within the movable groove and compress the second elastic element 403. The second elastic element 403 can drive the movable plate 402 to reset and move. The second elastic element 403 can be a spring or a spring block.

[0038] Reference Figure 1 and Figure 2 The top plate 100 is connected to the connector 103 by screws; the cutter head 200 is connected to the connector 103 by bolts. The connector 103 is L-shaped. The L-shaped connector 103 can be connected to both the top plate 100 and the cutter head 200, making the installation of the cutter head 200 more stable and less prone to loosening. The bolt connection method facilitates the replacement of the cutter head 200 and makes maintenance convenient.

[0039] Reference Figure 1 and Figure 2 The outer pressing plate 300 is connected to the moving block 301 by bolts.

[0040] Reference Figure 1 and Figure 2 The inner pressing plate 400 is connected to the movable plate 402 by bolts, and the number of bolts on the inner pressing plate 400 is at least two.

[0041] Reference Figure 1 and Figure 2 The top plate 100 includes a connector 101, which is installed on the top of the top plate 100. The connector 101 facilitates the connection of the top plate 100 with other devices. The top of the connector 101 may have an internal hexagonal groove to facilitate the connection with other devices.

[0042] During use, connect the cutter head 200 to the L-shaped connector 103 with bolts, ensuring a secure connection. Then, install the connector 103 to the bottom of the top plate 100 and secure it with screws. Place a whole piece of board (before cutting) under the top plate 100 and connect the board to the moving block 301 and the moving plate 402 with bolts. At this point, the board and the top plate 100 are the same size, covering the entire bottom of the top plate 100. Connect the top plate 100 to the output shaft of the cutting machine through the connector 101, ensuring a stable and reliable connection. Start the cutting machine, moving the top plate 100 downwards until the board contacts the cutting table. The cutter head 200 follows the top plate 100 downwards to cut the entire board. After cutting, the board is divided into an outer pressing plate 300 and an inner pressing plate 400, the shapes of which are adapted to the cutter head 200. Check whether the outer pressing plate 300 and the inner pressing plate 400 are installed correctly, whether the moving block 301 and the moving plate 402 can move freely within the groove 102 and the moving slot, and check whether the connection between the first elastic element 302 and the second elastic element 403 is firm. Place the material to be cut on the cutting table, ensuring the material is flat and accurately positioned. Start the cutting machine; the top plate 100 drives the cutter head 200, the outer pressing plate 300, and the inner pressing plate 400 downwards. The outer pressing plate 300 and the inner pressing plate 400 first press and fix the material, ensuring that the material will not move during the cutting process. The cutter head 200 passes between the outer pressing plate 300 and the inner pressing plate 400 to precisely cut the material. During the cutting process, the high wear resistance and dimensional stability of the cutter head 200 ensure cutting accuracy and efficiency. After cutting, the cutter head 200 is reset, and the outer pressing plate 300 and the inner pressing plate 400, under the action of the first elastic element 302 and the second elastic element 403, press and fix the cut material on the cutting table for easy subsequent operation.

[0043] In summary, compared with existing technologies, it has the following beneficial effects:

[0044] By installing a pressing plate around the blade that perfectly matches the blade shape, the stability of the material during the cutting process is ensured. The pressing plate can fit tightly against the material, preventing it from getting stuck in the blade due to vibration or displacement during the cutting process, effectively improving the cutting quality and operational safety.

[0045] The modular design allows for easy replacement of key components such as blades and pressure plates. Users can quickly change blades of different shapes and sizes, as well as corresponding pressure plates, according to different cutting needs, thus improving the flexibility and adaptability of the equipment.

[0046] The 200 blade is made of high-performance materials such as Cr12MO1V steel and is strengthened through processes such as ultra-deep cryogenic treatment, which significantly improves its wear resistance and service life, and helps to reduce the cost of cutting quality decline and frequent blade replacement caused by blade wear.
