Description

Technical Field

[0001] This utility model belongs to the field of metal sintered mesh processing technology, and in particular relates to a cutting device for metal sintered mesh. Background Technology

[0002] Metal sintered mesh is a new type of filter material manufactured using a special lamination and vacuum sintering process with multiple layers of woven metal wire mesh. It possesses high strength and overall rigidity. Its core structural features include: the interlacing mesh openings of each layer form a uniform filtration structure, typically consisting of multiple layers such as a protective layer, filter layer, separation layer, and support layer (e.g., five or six layers). This ensures both uniform and stable filtration accuracy and excellent mechanical strength. However, before being processed into corresponding filter elements, it needs to be cut to the appropriate size, but the following drawbacks still exist in the actual cutting process:

[0003] For example, in the utility model patent with publication number CN222923507U, a roller-cut edge trimming method is used for sintered felt. By setting up a support frame, push table, moving plate and cutting components, the problem of needing to adjust the cutting machine in multiple directions to cut different widths of sintered felt and the insufficient flexibility of the cutting limit is solved. However, the above solution can only perform straight edge trimming of long strips. For some circular filtering solutions, it is not possible to cut circular metal sintered mesh in one go.

[0004] Secondly, when cutting circular sintered metal mesh, it is easy to cause problems such as edge curling when cutting at the outer edge. It is also too dangerous to press it by hand. Therefore, circular cutting can easily reduce the pass rate.

[0005] Finally, different filtration devices require metal sintered mesh of different sizes, so a single cutting device cannot meet the needs and cannot cut metal sintered mesh of different diameters. Utility Model Content

[0006] The purpose of this utility model is to provide a cutting device for sintered metal mesh. By setting up a worktable, support arm, I-beam slider, cutting knife, center rod, pressure plate, and pressure block, it solves the problems of not being able to cut circular sintered metal mesh in one go, the edges of circular sintered metal mesh easily curling up when cutting, and the inability to cut sintered metal mesh of different diameters.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a cutting device for sintered metal mesh, comprising a worktable, a central rod, a support arm, and an I-shaped slider. A central rod is positioned at the center of the upper part of the worktable, with a pressure block rotatably connected to its bottom end. A support arm is rotatably connected to the lower outer periphery of the central rod, and an I-shaped slider is slidably inserted into the support arm. A servo motor is fixed to the top surface of the end of the I-shaped slider away from the support arm, and a bearing is fixed to the bottom surface of the end of the I-shaped slider away from the support arm, with a rotating shaft rotatably connected inside the bearing. A cutting blade is fixed to the end of the rotating shaft away from the support arm. Support rods are fixed to both sides of the end of the I-shaped slider away from the support arm, and an arc-shaped pressure plate is fixed to the bottom of both support rods.

[0009] Furthermore, a column is fixed to the upper end of the workbench, and a crossbeam is fixed to the top of the column, with the end of the crossbeam away from the column being threadedly connected to the central rod; a metal sintered mesh body is also placed on the upper surface of the workbench.

[0010] Furthermore, the upper part of the central rod is provided with a threaded section, which is screwed into the end of the crossbeam, and a handwheel is fixed at the upper end of the central rod. The bottom surface of the pressure block contacts and presses the upper surface of the metal sintered mesh body. The central rod, the metal sintered mesh body, and the central axis of the worktable are on the same vertical line.

[0011] Furthermore, an I-shaped sliding groove is provided inside the support arm, and the I-shaped sliding groove passes through the end of the support arm away from the central rod. A reinforcing frame is fixed to the outside of the end of the support arm away from the central rod, and the I-shaped slider is slidably disposed in the I-shaped sliding groove.

[0012] Furthermore, a main gear is fixed on the output shaft of the servo motor, and a secondary gear is fixed on the outer periphery of the shaft between the bearing and the cutting blade, with the main gear located above the secondary gear and meshing with it.

[0013] Furthermore, the outer and inner edges of the bottom surface of the pressure plate are connected with equally spaced balls, and the cutting blade is located outside the outer arc surface of the pressure plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention solves the problem of not being able to cut circular sintered metal mesh in one go by setting up a worktable, support arm, I-beam slider, cutting blade, and center rod. The main body of the sintered metal mesh to be cut is placed on the worktable, and the center rod is rotated to move down, so that the pressure block presses down on the main body of the sintered metal mesh. Then, the I-beam slider in the support arm is pulled to move the cutting blade to the corresponding cutting position. Then, the servo motor works, and the drive shaft rotates, so that the cutting blade rotates and cuts the main body of the sintered metal mesh. Then, the support arm and I-beam slider are rotated around the center rod, so that the cutting blade will form a circular cutting path and cut the next standard circular sintered metal mesh main body.

[0016] This invention solves the problem of edge curling when cutting circular sintered metal mesh by setting up a pressure plate and a pressure block. The rotating center rod lowers the pressure block and presses it to the center of the sintered metal mesh body. At this time, the arc-shaped pressure plate also lowers and presses it to the edge of the sintered metal mesh body. The part of the sintered metal mesh body outside the pressure plate is the part that needs to be cut off. During the entire cutting process, the pressure plate moves synchronously with the cutting blade, pressing the part that the cutting blade is cutting flat and preventing edge curling.

[0017] This invention solves the problem of being unable to cut metal sintered meshes of different diameters by setting up a support arm and an I-shaped slider. By moving the length of the I-shaped slider extending inside the support arm, the position of the cutting blade on the I-shaped slider can be changed. The cutting blade moves in a circle around the central rod to achieve circular cutting. Therefore, changing the combined length of the support arm and the I-shaped slider changes the cutting radius, thereby changing the diameter of the cut metal sintered mesh body.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-6 As shown, this utility model is a cutting device for sintered metal mesh, including a workbench 1, a central rod 2, a support arm 3, and an I-shaped slider 4. The central rod 2 is set at the center of the upper part of the workbench 1. A pressure block 201 is rotatably connected to the bottom end of the central rod 2. The support arm 3 is rotatably connected to the lower outer periphery of the central rod 2. The I-shaped slider 4 is slidably inserted into the support arm 3. A servo motor 401 is fixed to the top surface of the end of the I-shaped slider 4 away from the support arm 3. A bearing 406 is fixed to the bottom surface of the end of the I-shaped slider 4 away from the support arm 3. A rotating shaft 402 is rotatably connected to the bearing 406. A cutting blade 403 is fixed to the end of the rotating shaft 402 away from the support arm 3. Support rods 404 are fixed to both sides of the end of the I-shaped slider 4 away from the support arm 3. An arc-shaped pressure plate 405 is fixed to the bottom end of the two support rods 404.

[0029] The workbench 1 serves as the carrier for the cutting operation. The metal sintered mesh body 5 is placed on it, with the center rod 2 centered. During the cutting operation, the center rod 2 is rotated, causing the pressure block 201 to descend and press down on the metal sintered mesh body 5. At this time, the I-shaped slider 4 inside the moving support arm 3 extends, so that the cutting blade 403 is located at the cutting point. The servo motor 401 works, and the transmission shaft 402 rotates, causing the cutting blade 403 to rotate and cut the edge of the metal sintered mesh body 5. During this process, the pressure plate 405 connected to the I-shaped slider 4 through the support rod 404 presses down on the edge of the metal sintered mesh body 5. The cutting blade 403 adheres to the outer arc surface of the pressure plate 405 to perform the cutting operation. Then, the support arm 3 and the I-shaped slider 4 are rotated around the center rod 2, so that the cutting blade 403 will form a circular cutting path and cut a standard circular metal sintered mesh body 5.

[0030] A column 101 is fixed at the upper end of the workbench 1, and a crossbeam 102 is fixed at the top of the column 101. The end of the crossbeam 102 away from the column 101 is threadedly connected to the center rod 2. A metal sintered mesh body 5 is also placed on the upper surface of the workbench 1.

[0031] A crossbeam 102 is installed on the workbench 1 via a column 101. The end of the crossbeam 102 away from the column 101 is located above the center of the workbench 1, where a center rod 2 is connected. The center rod 2 can rotate and rise.

[0032] The upper part of the center rod 2 is provided with a threaded section 202, which is screwed into the end of the crossbeam 102. The upper end of the center rod 2 is fixed with a handwheel 203. The bottom surface of the pressure block 201 contacts and presses the upper surface of the metal sintered mesh body 5. The central axis of the center rod 2, the metal sintered mesh body 5, and the worktable 1 are on the same vertical line.

[0033] Rotate the center rod 2 by handwheel 203, and the threaded section 202 will descend within the crossbeam 102, causing the pressure block 201 to descend and press above the center of the metal sintered mesh body 5. After cutting, rotate the center rod 2 again to rise, and then remove the cut metal sintered mesh body 5.

[0034] An I-shaped groove 301 is provided inside the support arm 3, and the I-shaped groove 301 passes through the end of the support arm 3 away from the central rod 2. A reinforcing frame 302 is fixed to the outside of the end of the support arm 3 away from the central rod 2. The I-shaped slider 4 is slidably disposed in the I-shaped groove 301.

[0035] The I-shaped slider 4 can slide in the I-shaped groove 301 inside the support arm 3 to change the cutting radius. The reinforcing frame 302 is used to strengthen the structural strength of the end of the support arm 3 and increase stability.

[0036] A main gear 4011 is fixed on the output shaft of the servo motor 401. A secondary gear 4021 is fixed on the outer periphery of the rotating shaft 402 between the bearing 406 and the cutting blade 403. The main gear 4011 is located above the secondary gear 4021 and meshes with the secondary gear 4021.

[0037] The servo motor 401 operates, driving the main gear 4011 to rotate, which in turn drives the transmission gear 4021 to rotate, thereby causing the rotating shaft 402 to rotate, which in turn causes the cutting blade 403 to rotate to perform the cutting operation.

[0038] The outer and inner edges of the bottom surface of the pressure plate 405 are connected with equally spaced balls 4051, and the cutting blade 403 is located outside the outer arc surface of the pressure plate 405.

[0039] The ball bearing 4051 helps the pressure plate 405 move more smoothly with the I-beam slider 4 while pressing the metal sintered mesh body 5.

[0040] The specific working principle of this utility model is as follows: First, the metal sintered mesh body 5 to be cut is placed on the workbench 1. By rotating the center rod 2 through the handwheel 203, the threaded section 202 descends within the crossbeam 102, causing the pressure block 201 to descend and press down above the center of the metal sintered mesh body 5. Then, according to the required cutting radius, the length of the I-beam slider 4 extending within the support arm 3 is moved, thereby changing the position of the cutting blade 403 on the I-beam slider 4 (after the position of the I-beam slider 4 is determined, an additional locking structure can be added to lock the I-beam slider 4 to the support arm 3). At this time, the cutting blade 403 is located at the cutting point, and the servo motor 401 works. The main gear 4011 is driven to rotate, meshing with the transmission gear 4021 to rotate, thereby rotating the shaft 402, which in turn causes the cutting blade 403 to rotate to perform the cutting operation. During this process, the pressure plate 405 connected to the I-shaped slider 4 by the support rod 404 presses against the edge of the metal sintered mesh body 5. The cutting blade 403 adheres to the outer arc surface of the pressure plate 405 to perform the cutting operation. Then, the support arm 3 and the I-shaped slider 4 are rotated around the center rod 2, so that the cutting blade 403 will form a circular cutting path to cut a standard circular metal sintered mesh body 5. After cutting, the center rod 2 is rotated to rise, and the cut metal sintered mesh body 5 can be taken out.

[0041] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
