[0002] In machining, the processing of thin metal sheet materials includes cutting operations, such as cutting steel plates, aluminum plates, and copper plates. Generally, a hydraulic system is used to make the cutter rise and fall vertically. The descending cutter cuts the steel plate material to complete the cutting operation. The cutter is a conventional tool used to cut steel plate materials.

[0003] The cutter has multiple screw holes and is usually fixed to the cutter holder by multiple equally spaced bolts. After long-term use, the cutting edge of the cutter will show defects such as wear, deformation or chipping, and needs to be replaced. However, the cutter with multiple bolts is inconvenient to disassemble and assemble. If a lot of dust and impurities adhere to the joint between the bolt and the cutter, it will increase the frictional resistance and affect the smoothness of bolt disassembly, resulting in the disadvantage of not being able to disassemble and assemble quickly.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 6This utility model provides a technical solution: a quick-release cutter structure, including a cutting cutter 1, on the surface of which a limiting groove 11 is formed, which cooperates with a pressing block 22 to facilitate a sliding connection between the pressing block 22 and the cutting cutter 1; a cutter mounting base 4, which is firmly fixed to an external lifting device by bolts, and serves to mount the cutting cutter 1. A limiting protrusion 3 penetrating the cutting cutter 1 is fixedly connected to the inner surface of the cutter mounting base 4. When the cutting cutter 1 is installed, it is mounted on the inner surface of the cutter mounting base 4, and the cutting cutter 1 and the cutting cutter... The inner surface of the blade mounting base 4 fits, and the limiting protrusion 3 penetrates the cutting blade 1, positioning the cutting blade 1 and ensuring accurate installation. Limiting guide rails 42 are fixedly connected to the surfaces at both ends of the blade mounting base 4. These guide rails 42 limit the movement of the symmetrically distributed hinged covers 2, preventing them from tilting. A second through groove 41 is formed on the surface of the blade mounting base 4, and the pressing block 22 engages with the corresponding second through groove 41, without affecting the hinged covers 2's opening to both sides. The symmetrically distributed hinged covers 2... The surfaces of plate 2 and the cutter mounting base 4 are aligned to clamp the cutting cutter 1, preventing it from loosening inside the cutter mounting base 4. A pressing block 22 is fixedly connected to the hinged cover plate 2 and embedded in the limiting groove 11. The pressing block 22 is embedded inside the cutting cutter 1 to press it firmly. A first through groove 21 is provided on the surface of the hinged cover plate 2 facing the cutter mounting base 4 to facilitate the passage of the limiting plate 5. The reinforcing assembly includes a reinforcing frame 7 sleeved on the outside of the hinged cover plate 2 and the cutter mounting base 4, a limiting plate 5 that slides through the reinforcing frame 7, and a spiral reinforcement that passes through the limiting plate 5. The screw 6 and the reinforcing frame 7 are assembled on the outside of the hinged cover plate 2 and the cutter mounting base 4 to secure the hinged cover plate 2 and the cutter mounting base 4, preventing the hinged cover plate 2 from moving. The limiting plate 5 passes through the reinforcing frame 7, the cutter mounting base 4 and the hinged cover plate 2. Then, by tightening the reinforcing screw 6, the combination of the reinforcing frame 7, the cutter mounting base 4 and the hinged cover plate 2 is made stable. In this application, by loosening the reinforcing screw 6, the limiting plate 5 is pulled out to the outside, the reinforcing frame 7 is moved vertically upward, and then the corresponding hinged cover plates 2 are opened to both sides to remove the separately assembled cutting cutter 1. The cutting cutter 1 can be quickly disassembled.

[0028] In this embodiment, the cross-section of the pressing block 22 is a right-angled trapezoid. The pressing block 22 cooperates with the limiting groove 11. The contact area between the pressing block 22 and the cutting blade 1 is large, and the support area is large, which can support the cutting blade 1. A third through groove 43 that cooperates with the pressing block 22 is provided on the surface of the cutting blade mounting base 4. When the hinged cover 2 is opened and slid to one side, the pressing block 22 passes through the third through groove 43 and does not affect the opening of the hinged cover 2.

[0029] In this embodiment, the cross-section of the limiting guide rail 42 is a "T" shaped structure, which limits the hinged cover plate 2. The surface of the hinged cover plate 2 facing the cutter mounting base 4 is provided with a rail groove that cooperates with the limiting guide rail 42. The hinged cover plate 2 is limited by the limiting guide rail 42, so that it moves in a predetermined direction and prevents the hinged cover plate 2, which is in a vertical state, from falling down.

[0030] In this embodiment, the first through slot 21 and the corresponding second through slot 41 have the same geometry. The reinforcing frame 7 has a first square hole with a rectangular orthographic projection. The limiting plate 5 can pass through the first square hole. The cutting blade 1 has a mounting square hole with a rectangular orthographic projection. The limiting protrusion 3 on the cutting blade mounting seat 4 passes through the mounting square hole to ensure accurate installation of the cutting blade 1. The first square hole has the same geometry as the corresponding first through slot 21. The hinged cover plate 2 fits with the cutting blade mounting seat 4. The reinforcing frame 7 is sleeved on the outside of the hinged cover plate 2 and the cutting blade mounting seat 4. When the first square hole corresponds to the first through slot 21 and the second through slot 41, the limiting plate 5 can pass through the first square hole, the second through slot 41, and the first through slot 21.

[0031] In this embodiment, one end of the limiting plate 5 is a right-angle structure, and one end of the reinforcing screw 6 is fixedly connected to a handwheel. The end of the reinforcing screw 6 that passes through the limiting plate 5 is connected to the reinforcing frame 7 and the cutter mounting seat 4 by threaded engagement. The limiting plate 5 passes through the reinforcing frame 7, the cutter mounting seat 4 and the hinged cover plate 2. Then, through the tightening action of the reinforcing screw 6, the combination of the reinforcing frame 7, the cutter mounting seat 4 and the hinged cover plate 2 is made stable.

[0032] Working principle and usage process of this utility model:

[0033] When the cutting blade 1 is installed on the cutting blade mounting base 4, which is always in a fixed state, the cutting blade 1 is installed on the inner surface of the cutting blade mounting base 4. The cutting blade 1 matches the inner surface of the cutting blade mounting base 4, and the limiting protrusion 3 penetrates the cutting blade 1, so that the cutting blade 1 is positioned and the position is accurate.

[0034] The symmetrically distributed hinged cover plates 2 are moved from both sides to opposite directions. The pressing block 22 is embedded in the limiting groove 11 on the surface of the cutting blade 1. The pressing block 22 has a large contact area and a large support area with the cutting blade 1, which can support the cutting blade 1 and achieve the effect of pressing the cutting blade 1.

[0035] At this time, the hinged cover plate 2 and the cutter mounting base 4 clamp the cutting cutter 1;

[0036] Then, the reinforcing frame 7 is moved vertically downwards so that the first square hole corresponds to the first through slot 21 and the second through slot 41;

[0037] The sliding limiting plate 5 passes through the first square hole and the second through slot 41 and the first through slot 21, that is, the limiting plate 5 passes through the reinforcing frame 7, the cutter mounting seat 4 and the hinged cover plate 2. Finally, the combination of the reinforcing frame 7, the cutter mounting seat 4 and the hinged cover plate 2 is stabilized by the tightening action of the reinforcing screw 6.

[0038] In summary: In this utility model, the cutter has an assembly structure designed for quick assembly and disassembly. The hinged cover plate 2 and the cutter mounting base 4 are separate from the cutting cutter 1. Loosen the reinforcing screw 6, pull out the limiting plate 5 to the outside, move the reinforcing frame 7 vertically upward, and then move the hinged cover plate 2 to both sides to remove the separate assembled cutting cutter 1. The cutting cutter 1 can be quickly disassembled.

[0039] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
