Detailed Implementation

[0033] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1 and Figure 3As shown, this utility model provides a highly reactive metal cutting device, which can be used to cut highly reactive metal materials that cannot be directly cut in a conventional environment. For example, it can cut sodium and potassium. The cutting device includes a housing 100, a pressure-bearing component, a baffle 202, a pressure plate 601, and a blade 600. The housing 100 contains an isolation fluid 700. The isolation fluid 700 is a flowing liquid used to create a cutting environment that does not come into contact with air or water. Different isolation fluids 700 can be selected for different reactive metals. For example, kerosene or paraffin oil can be used for metals or alloys such as sodium and potassium. A through hole 101 is provided on the side wall of the housing 100. The workpiece 500 to be cut is placed on the pressure-bearing component. Moving the pressure-bearing component allows it to partially or completely pass through the through hole 101, simultaneously carrying the workpiece in and out of the housing 100. In this embodiment, the workpiece 500 to be cut is a highly reactive metal. The baffle 202 is fixedly connected to the side of the pressure-bearing component near the through hole 101. The baffle 202 is located outside the housing 100, and its orthographic projection on the housing 100 covers the through hole 101. During the cutting process of the workpiece 500, the baffle 202 is fixedly connected to the outer wall of the housing 100 and closes the end of the through hole 101. The area of ​​the pressure plate 601 is smaller than the opening area of ​​the housing 100, and the pressure plate 601 can be moved perpendicular to the surface of the pressure member, thereby extending the pressure plate 601 into the housing 100. The blade 600 is fixed to the side of the pressure plate 601 near the housing 100. The blade 600 moves with the pressure plate 601 and contacts the workpiece 500, cutting it into multiple pieces under pressure. When the blade 600 contacts and cuts the workpiece 500, it is placed in the isolation fluid 700.

[0035] Please see Figure 1 and Figure 3As shown, in this invention, before cutting, the pressure-bearing component is pulled out of the housing 100 through the through hole 101, and the workpiece 500 to be cut is placed directly on the pressure-bearing component. Then, the pressure-bearing component is pushed back into the housing 100, and the workpiece 500 to be cut simultaneously passes through the through hole 101 and enters the housing 100. Next, the housing 100 is filled with an isolation fluid 700, which covers the height of the through hole 101 and also submerges the workpiece 500. In this embodiment, the pressure-bearing component can be positioned in the middle of the housing 100, and the isolation fluid 700 can fill at least three-quarters of the housing 100. When the blade 600 and the pressure plate 601 enter the housing 100, it is ensured that the blade 600 is placed in the isolation fluid 700, reducing the possibility of air entering and ensuring that the cutting is carried out in an absolutely safe environment. In this embodiment, before the part to be cut 500 is inserted, a portion of the isolation fluid 700 can be placed inside the housing 100, with the aim of preventing the isolation fluid 700 from overflowing the through hole 101. After fixing the position of the pressure-bearing component, another portion of the isolation fluid 700 is then inserted, so that the time for the isolation fluid 700 to fill is as short as possible, thereby reducing the time the part to be cut 500 is exposed to air.

[0036] Please see Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the pressure-bearing component includes a pressure plate 200. The pressure plate 200 is slidably connected to the wall of the through hole 101, and can pass through the through hole 101 in a direction perpendicular to the side wall of the housing 100 to complete the loading and unloading of the workpiece 500. The pressure plate 200 can also move in a direction parallel to the side wall of the housing 100 to adjust the position of the workpiece 500 contacting the blade 600. The pressure plate 200 is fixedly connected to the baffle 202, and when the baffle 202 is connected to the outer side wall of the housing 100, the side of the pressure plate 200 opposite to the baffle 202 is connected to the inner side wall of the housing 100. During cutting, in addition to the strength of the pressure plate 200 itself, the contact area between the pressure plate 200 and the hole wall of the through hole 101, and the contact area between the pressure plate 200 and the side wall of the housing 100, all contribute to improving the pressure-bearing capacity of the pressure plate 200. In this embodiment, the pressure plate 200 is higher than the inner bottom wall of the housing 100, which facilitates the pre-filling of a portion of the isolation fluid 700. Specifically, the isolation fluid 700 can be filled to a position where it does not overflow the through hole 101, thereby pre-expelling some air from the housing 100 and preventing air from not being completely expelled from the cutting environment during the subsequent filling of the isolation fluid 700. In this embodiment, a pressure relief hole 201 is provided on the pressure plate 200. When the baffle 202 is connected to the outer side wall of the housing 100, the isolation fluid 700 can pass through the pressure relief hole 201 and submerge the workpiece 500 being cut. The pressure relief hole 201 ensures that the pre-injection of the isolation fluid 700 is not obstructed.

[0037] Please see Figures 1 to 3 As shown, in one embodiment of this utility model, the pressure-bearing component includes a pressure-bearing mesh 400, which is embedded and fixed on the pressure plate 200. The pressure-bearing mesh 400 is fixed on the side of the pressure plate 200 near the blade body 600, and covers the pressure relief hole 201. The part to be cut 500 is placed on the pressure-bearing mesh 400. In this embodiment, the pressure-bearing mesh 400 has a mesh structure, which does not affect the passage of the isolation fluid 700. The pressure-bearing mesh 400 is not only used to place the part to be cut 500, but also to prevent the part to be cut 500 from being washed away due to excessively high fluid flow rate when the isolation fluid 700 is introduced. In this embodiment, a stepped structure 206 is provided on the pressure plate 200, and the stepped structure 206 is located at the end of the pressure relief hole 201. The pressure mesh 400 is fixed on the stepped structure 206, thereby being snapped onto the pressure plate 200. The pressure mesh 400 can be fixed in the cutting direction without affecting the convenient disassembly and assembly of the pressure mesh 400, which is beneficial for the daily replacement of the pressure mesh 400.

[0038] Please see Figures 1 to 3 As shown, in one embodiment of this utility model, the cutting device includes a handle 203, which is fixed to a baffle 202. The handle 203 can move the baffle 202 along a direction parallel to the side wall of the housing 100. At this time, the baffle 202 is slidably connected to the outer side wall of the housing 100. During the movement of the baffle 202, the baffle 202 covers the end of the through hole 101. The baffle 202 is moved by the handle 203, improving the convenience of manual cutting. In other embodiments of this utility model, for occasions where the cutting device is frequently used, a driving device, such as a pneumatic cylinder or hydraulic cylinder, can be designed to drive the handle 203 to move along a direction parallel to the side wall of the housing 100, thereby driving the movement of the baffle 202, the pressure plate 200, and the pressure mesh 400. During the movement of the baffle 202, allowing the baffle 202 to slide against the outer side wall of the pressure housing improves the stability of the movement of the baffle 202. In this embodiment, a positioning groove 102 is provided on the housing 100, and a limiting hole 204 is provided on the baffle 202. When cutting the workpiece 500, a fixing member 207 is installed in the positioning groove 102 and the limiting hole 204, and the baffle 202 is fixed to the outer wall of the housing 100. Specifically, the position where the positioning groove 102 and the limiting hole 204 communicate can be set to the position where the pressure plate 200 abuts against the wall of the through hole 101. Then, the position of the baffle 202 is fixed and stabilized by installing the fixing member 207. This allows the pressure plate 200 to stably withstand the pressure of the cutting blade 600 during the cutting process. In this embodiment, the area of ​​the baffle 202 is larger than the area of ​​the through hole 101. As the baffle 202 moves along a direction parallel to the side wall of the housing 100, the baffle 202 always blocks the end of the through hole 101.

[0039] Please see Figures 1 to 3 As shown, in one embodiment of this utility model, the cutting device includes a first sealing element 103 and a second sealing element 205. The first sealing element 103 is disposed at one end of the through hole 101 near the baffle 202, and is embedded in the outer wall of the housing 100. The second sealing element 205 is disposed on one side of the through hole 101 of the baffle 202, and is embedded in the surface where the baffle 202 connects to the housing 100. During the cutting of the workpiece 500, the first sealing element 103 and the second sealing element 205 come into contact to improve the sealing performance of the baffle 202 in blocking the through hole 101, preventing the isolation fluid 700 from flowing out and preventing air from entering from the side of the housing 100. In this embodiment, the first sealing element 103 and the second sealing element 205 can be embedded sealing rings.

[0040] Please see Figures 1 to 4 As shown, in one embodiment of this utility model, the shape of the pressure plate 601 is consistent with the opening shape of the housing 100. Furthermore, the area of ​​the pressure plate 601 is smaller than the opening area of ​​the housing 100. When the pressure plate 601 is placed inside the housing 100, a flow channel exists between the edge of the pressure plate 601 and the inner wall of the housing 100, allowing the isolation fluid 700 to pass through. When the pressure plate 601 drives the blade 600 into the housing 100, it compresses the isolation fluid 700 within the housing 100. The isolation fluid 700 submerges the blade 600 and may also submerge the pressure plate 601, thereby ensuring that the blade 600 is placed within the isolation fluid 700, thus isolating the cutting environment from air. In this embodiment, the shape of the pressure mesh 400 is consistent with the opening shape of the housing 100, and the area of ​​the pressure mesh 400 is smaller than the area of ​​the housing 100, so that when the pressure plate 601 is pressed into the isolation fluid 700, the isolation fluid 700 can be squeezed out evenly.

[0041] Please see Figure 1 and Figure 3 As shown, in one embodiment of this utility model, the cutting device includes a leak-proof basin 300, with a receiving box 100 placed inside the leak-proof basin 300, and the height of the leak-proof basin 300 being lower than the height of the handle 203. During the process of the pressure plate 601 entering the receiving box 100, the isolation fluid 700 flows out from the flow channel and may also overflow the receiving box 100. The leak-proof basin 300 collects the overflowing isolation fluid 700. In this embodiment, the receiving box 100, pressure plate 200, pressure mesh 400, baffle 202, blade 600, and pressure plate 601 are all made of glass to reduce the possibility of a reaction with active metals.

[0042] Please see Figure 1 , Figure 3 , Figures 5 to 7 As shown, in one embodiment of this utility model, the blade 600 is in a mesh shape. This utility model does not limit the opening shape of the pressure plate 601 and the housing 100. In this embodiment, the housing 100 can be cylindrical, and the pressure plate 601 has a circular cross-section. In another embodiment of this utility model, the pressure plate 601 can have a rectangular cross-section. The blade 600 can be a mesh shape with closed edges, such as... Figure 5 and Figure 7 As shown, this improves the uniformity of the cut. The blade body 600 can also be a mesh-like structure with open edges, such as... Figure 6 As shown. In this embodiment, the cutting device further includes a driving component 602. The driving component 602 is connected to the side of the pressure plate 601 opposite to the conductor via a connecting rod 603. In this embodiment, the driving component 602 can be manually driven, thereby precisely controlling the cutting force and improving the convenience of cutting. In another embodiment of this utility model, the driving component 602 can be a cylinder, a hydraulic cylinder, etc., and the connecting rod 603 is the driving rod of the driving component 602, thereby improving the safety of cutting.

[0043] The embodiments of this utility model disclosed above are merely illustrative of the present utility model. The embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described.
