Description

Technical Field

[0001] This utility model belongs to the technical field of cutting devices, specifically relating to a metal workpiece cutting device. Background Technology

[0002] Metal workpieces are items made of metal materials (such as steel, aluminum, copper, etc.), especially referring to parts that are semi-finished or finished products in industrial processing. They can be structural components, decorative items, or functional parts.

[0003] In the processing of metal workpieces, cutting devices are needed to meet different processing requirements. Currently, existing cutting devices are prone to blade wear after prolonged use, affecting subsequent cutting accuracy. Therefore, regular sharpening or replacement of the cutting blades is necessary. However, replacing the cutting blades in existing devices often requires multiple steps, making it inconvenient and hindering quick blade replacement. Therefore, there is an urgent need for a new metal workpiece cutting device.

[0004] A patent with publication number CN222242832U discloses an adjustable lithium battery electrode cutting device, which includes a cutting blade, a contact plate, a sliding plate, a rod, a slot, a blade holder, a fixing plate, and fixing bolts. To remove the cutting blade, the contact plate is rotated to release its restriction on the sliding plate. The sliding plate is then moved to disengage the rod from the slot, releasing the sliding plate's obstruction of the blade holder. Subsequently, the fixing bolts on the fixing plate are rotated to release their restriction on the fixing plate and mounting bracket, allowing the mounting bracket to slide on the blade holder for disassembly of the cutting blade.

[0005] However, when disassembling the cutting blade using the above method, it is necessary not only to rotate the abutment plate to release its restriction on the slide plate, but also to move the slide plate to release its blockage on the blade holder. After releasing the blockage on the blade holder, it is also necessary to rotate the fixing screws to release the restriction on the mounting bracket. The entire disassembly process involves many steps, which are interconnected and cumbersome to operate. It is not convenient to use and does not facilitate the quick disassembly of the cutting blade.

[0006] To address the problems existing in the background technology, this utility model provides a metal workpiece cutting device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A metal workpiece cutting device includes a grinding box. Two fixed frames are symmetrically fixed on the top of the grinding box. Each fixed frame contains a sliding plate that is limited and slidably mounted vertically. A lifting mechanism acting on the sliding plate is provided on each fixed frame. The two sliding plates are connected by several rotating cylinders. A connecting assembly is provided between adjacent rotating cylinders. A driving mechanism for rotating the rotating cylinders is provided on the moving frame. The connecting assembly includes a sliding shaft. Each rotating cylinder contains both a sliding shaft that is limited and slidably mounted and a connecting groove. An elastic element is provided between the sliding shaft and the rotating cylinder. Bolts acting on the sliding shaft are provided on the rotating cylinders.

The cutting blade is slidingly connected to the outer surface of the sliding shaft.

[0009] Furthermore, the lifting mechanism includes a first motor, a threaded rod that is rotatably mounted in the vertical direction and a guide rod that is fixedly mounted in the vertical direction inside the fixed frame, and a moving plate that is threadedly engaged with the threaded rod and slidably engaged with the guide rod; the first motor is fixedly mounted on the fixed frame, and the output shaft of the first motor is coaxially and fixedly connected to the top of the threaded rod.

[0010] Furthermore, the driving mechanism includes a second motor, the second motor is fixedly mounted on the surface of the moving plate, a rotating shaft is rotatably arranged inside the moving plate, the output shaft of the second motor is fixedly connected to the rotating shaft, and the rotating shaft is fixedly connected to the rotating cylinder.

[0011] Furthermore, the rotating cylinder has a clearance hole for the bolt to pass through, and the sliding shaft has a threaded hole for the bolt to mate with.

[0012] Furthermore, a limiting groove is provided inside the rotating cylinder to limit the sliding of the sliding shaft.

[0013] Furthermore, the elastic element includes a spring, with a spring provided between the sliding shaft and the rotating cylinder, and the spring located in the limiting groove; one end of the spring is fixedly connected to the sliding shaft, and the other end is fixedly connected to the inner wall of the limiting groove.

The entire disassembly process is simple and convenient, facilitating the quick disassembly of the cutting blade.

[0017] 2. This application uses bolts to restrict the sliding shaft, allowing for a secure connection between two adjacent rotating cylinders via the sliding shaft and connecting groove. This, combined with the cooperation of the clamping plate and the limiting plate, effectively clamps and limits the cutting blade. Through this technical means, when replacing the cutting blade at different positions, only the connection between the two rotating cylinders corresponding to that cutting blade needs to be disconnected; it is not necessary to disconnect the connections between other rotating cylinders one by one, making it more convenient to use and providing better practical results.

[0018] 3. The bolts in this application can be directly screwed into the sliding shaft, thereby improving the limiting effect on the sliding shaft, better restricting the cutting blade, ensuring safety during cutting operations, and further improving the practical effect of this application.

[0027] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a metal workpiece cutting device, including a grinding box 1, two fixed frames 4 are symmetrically fixed on the top of the grinding box 1, and a movable plate 8 is slidably arranged in each fixed frame 4 in the vertical direction. The fixed frame 4 is provided with a lifting mechanism that acts on the movable plate 8.

[0028] Two movable plates 8 are connected by several rotating cylinders 10. A connecting component is provided between two adjacent rotating cylinders 10. The movable plate 8 is provided with a driving mechanism to drive the several rotating cylinders 10 to rotate.

[0029] Among them, such as Figure 2 As shown, the lifting mechanism includes a first motor 7, a threaded rod 6 that is rotatably mounted in the vertical direction and a guide rod 5 that is fixedly mounted in the vertical direction inside the fixed frame 4, and a moving plate 8 that is threadedly engaged with the threaded rod 6 and slidably engaged with the guide rod 5; the first motor 7 is fixedly mounted on the fixed frame 4, and the output shaft of the first motor 7 is coaxially and fixedly connected to the top of the threaded rod 6.

[0030] Among them, such as Figure 2 As shown, the drive mechanism includes a second motor 16. The second motor 16 is fixedly mounted on the surface of the moving plate 8. A rotating shaft 9 is rotatably arranged inside the moving plate 8. The output shaft of the second motor 16 is fixedly connected to the rotating shaft 9. The rotating shaft 9 is fixedly connected to the rotating cylinder 10.

[0031] Among them, such as Figures 3-4 As shown, the connecting assembly includes a sliding shaft 11. Each rotating cylinder 10 has a sliding shaft 11 that is both limited and slidably arranged, and a connecting groove 102 is also provided. An elastic element is provided between the sliding shaft 11 and the rotating cylinder 10, and a bolt 13 that acts on the sliding shaft 11 is provided on the rotating cylinder 10.

[0032] Each rotating cylinder 10 is integrally fixed with a limiting plate 103, and each sliding shaft 11 is integrally fixed with a clamping plate 14. The sliding shaft 11 in each rotating cylinder 10 is engaged with the connecting groove 102 opened in the adjacent rotating cylinder 10. The limiting plate 103 on each rotating cylinder 10 clamps the cutting blade 15 between the clamping plate 14 on the adjacent sliding shaft 11. The cutting blade 15 is slidably connected to the outer surface of the sliding shaft 11.

[0033] Furthermore, a clearance hole is provided on the rotating cylinder 10 for the bolt 13 to pass through, and a threaded hole is provided on the sliding shaft 11 to mate with the bolt 13.

[0034] Furthermore, a limiting groove 101 is provided inside the rotating cylinder 10 to limit the sliding of the sliding shaft 11.

[0035] The elastic element includes a spring 12. A spring 12 is provided between the sliding shaft 11 and the rotating cylinder 10. The spring 12 is located in the limiting groove 101. One end of the spring 12 is fixedly connected to the sliding shaft 11, and the other end is fixedly connected to the inner wall of the limiting groove 101.

[0036] In addition, a fixing plate 2 is fixedly installed inside the grinding box 1, and several grinding stones 3 are fixedly installed on the fixing plate 2, with each grinding stone 3 corresponding to a cutting blade 15.

[0037] Furthermore, the surface of the grinding box 1 is provided with several through slots for the cutting blade 15 to pass through.

[0038] Additionally, it should be noted that the grinding box 1 can be equipped with a water spraying component as in the prior art, and the grinding box 1 is equipped with a limiting component that acts on the metal workpiece. Both of these are prior art, and this application does not specifically limit them.

[0039] Working principle: When cutting is required, the metal workpiece to be cut is placed on top of the grinding box 1. The second motor 16 is started, and the output shaft of the second motor 16 drives several rotating cylinders 10 to rotate. The rotating cylinders 10 drive the cutting blade 15 to rotate through the sliding shaft 11. During this process, the first motor 7 is started, and the threaded rod 6 drives the moving plate 8 and the rotating cylinders 10 to descend, so that the cutting blade 15 contacts the metal workpiece for cutting.

[0040] When the cutting blade 15 needs to be sharpened, the first motor 7 is started, causing the cutting blade 15 to enter the interior of the sharpening box 1 through the through slot and come into contact with the sharpening stone 3. Subsequently, the second motor 16 is started to drive the cutting blade 15 to rotate for sharpening operations.

[0041] When the cutting blade 15 needs to be replaced, rotate the bolt 13 to release the bolt 13 from its restriction on the sliding shaft 11. Then, pull the sliding shaft 11 and compress the spring 12 to disengage the sliding shaft 11 from the connecting groove 102, and then slide the cutting blade 15 off.

[0042] Then, slide the cutter 15 that needs to be replaced onto the surface of the sliding shaft 11, release the sliding shaft 11, and the sliding shaft 11 will be stuck in the connecting groove 102 under the elastic action of the spring 12, so that the clamping plate 14 and the limiting plate 103 press against the cutter 15.

[0043] Finally, tighten bolt 13 by turning it.

[0044] The replacement process for the cutting blade 15 in this application is simple to operate and more convenient to use, facilitating the quick replacement of the cutting blade 15. Furthermore, when replacing the cutting blade 15 in different positions, this application only requires disconnecting the connection between the two rotating cylinders 10 corresponding to that cutting blade 15, eliminating the need to disconnect other rotating cylinders 10 one by one, making it more convenient to use and providing better practical results.
