Description

Technical Field

[0001] The present application relates to the field of diamond tool technology, and in particular to a test block preparation device for testing composite granite tool head matrix materials. Background Art

[0002] Composite granite is an artificial stone made from composite plywood, primarily used for floor and wall decoration. Diamond bits are typically used to cut granite. Due to the complex nature of granite, the bits required for granite cutting require exceptional sharpness and hardness.

[0003] A diamond bit consists of a matrix material and diamond particles. During preparation, the diamond particles are distributed between adjacent layers of the matrix material. After multiple layers are laid, a press is used to pressurize and / or sinter the diamond bit to form a block. The matrix material is made by mixing one or more of a single metal powder, pre-alloyed powder, or other materials according to a specific ratio and application requirements. When mixing the matrix material, it is usually necessary to first use the matrix material to make a test block, which is then tested to determine characteristics such as the matrix's grip and wear properties.

[0004] In order to improve the accuracy of the matrix material test data, the actual situation of the diamond bit is usually simulated in the test block, and some diamond particles are filled to further test the bonding performance of the diamond particles with the matrix material, the holding force of the matrix material and other performance conditions.

[0005] To improve the efficiency of matrix material formulation testing, test blocks are often prepared manually by first filling a layer of powdered matrix material into a tooling mold, then placing diamond particles on top of this layer, and then filling the tooling mold with a new layer of matrix material to form the test block. This preparation process is prone to problems such as multiple diamond particles being located in the same position on the matrix material and uneven matrix material layers, which in turn affect the accuracy of testing the test block for properties such as bonding performance and matrix material holding force. Summary of the Invention

[0006] In order to improve the detection accuracy of the holding force and other properties of the matrix material through the detection of the test block, the present application provides a test block preparation device for testing the matrix material of the composite granite cutter head.

[0007] The present application provides a test block preparation device for composite granite cutter head matrix material testing using the following technical solutions:

[0008] A test block preparation device for testing composite granite tool head matrix materials, comprising a workbench, a preparation mold, a feeding mechanism, a pressurizing mechanism, and a demoulding mechanism; the preparation mold is arranged on the workbench, and the preparation mold is provided with a preparation groove for accommodating matrix sheets; the feeding mechanism is used to fill the matrix material into the preparation groove; the pressurizing mechanism is arranged above the preparation mold, and is used to pressurize the matrix material filled in the preparation groove; the pressurizing mechanism includes a pressurizing head, and the surface of the pressurizing head facing the preparation groove is provided with a molding protrusion; the demoulding mechanism is arranged below the preparation mold, and is used to eject the matrix sheets in the preparation groove.

[0009] By adopting the above technical solution, when preparing the test block, the preparation groove is first filled with the matrix material using the feeding mechanism, and then the matrix material in the preparation groove is pressurized by the pressing mechanism to form a matrix sheet; because the pressing head is provided with a forming protrusion, a groove is formed in the matrix sheet, and the groove is used to place the diamond; the demolding mechanism then removes the matrix sheet from the preparation groove, and the tester places the diamond in the groove of the matrix sheet. Then, according to the test requirements, the required number of layers of matrix sheets and diamonds are stacked on the matrix sheet. After the stacking is completed, the test block is formed by sintering or cold pressing. Since the groove is formed in the matrix sheet when the diamond is placed, the diamond can be placed in the specified position according to the test requirements and the diamond will not shift during the forming process of the test block, effectively improving the test accuracy of various properties of the matrix material used to make the test block.

[0010] Optionally, the loading mechanism includes a material storage box, a material delivery pipe and a first drive component; the material storage box has a material storage cavity, and the material delivery pipe is connected to the material storage cavity below the material storage box; an opening and closing component is provided in the material delivery pipe, and the opening and closing component is used to control the connection or isolation of the inner cavity of the material delivery pipe; the output end of the first drive component is connected to the material storage box, and the first drive component is used to drive the material storage box to move above the preparation tank.

[0011] By adopting the above technical solution, under normal circumstances, the opening and closing component will isolate the inner cavity of the conveying pipe; when loading, the first driving component is used to move the storage box and the conveying pipe to the top of the preparation tank, and the inner cavity of the conveying pipe is connected through the opening and closing component, so that the storage cavity and the preparation tank are connected, so that the material in the storage cavity can fall into the preparation tank for loading.

[0012] and a transmission mechanism which is fixed to the side panel that is located adjacent to the loading platform and which is located adjacent to the loading platform, and a transmission mechanism which is fixed to the side panel that is located adjacent to the loading platform and which is located adjacent to the loading platform.

[0013] By adopting the above technical solution, the first and second through-ports are disconnected, so the end of the feed pipe is not connected to the material storage chamber, and the carcass material above the sliding plate does not fall. During loading, the feed pipe is moved to the top of the preparation tank by the first drive assembly. The rotary motor is then activated, which drives the second rotating shaft via the first rotating shaft to rotate. The second rotating shaft drives the rotating plate to rotate, so that the first and second through-ports are intermittently connected, allowing the carcass material to fall into the preparation tank through the first and second through-ports. At the same time, the rotating plate, through the cooperation of the internal and external threads, drives the second rotating shaft to move toward the preparation tank. At the same time, the second rotating shaft drives the rotating blade to rotate, so that the rotating blade moves toward the preparation tank while rotating. The rotating blade is controlled to gradually move to the bottom of the preparation tank. During this movement, the carcass material in the preparation tank is stirred, which not only improves the mixing uniformity of the carcass material, but also smoothes the carcass material in the preparation tank to improve the distribution uniformity of the carcass material in the preparation tank, thereby improving the density uniformity of the test block. Finally, the rotating motor drives the first rotating shaft to rotate in the opposite direction, thereby driving the rotating blades, the rotating plate and the sliding plate to move upward and reset.

[0014] Optionally, a sliding protrusion is provided on the peripheral side of the sliding plate, and a sliding groove is provided on the inner wall of the conveying pipe along its length direction, and the sliding groove is used for the sliding connection of the sliding protrusion.

[0015] By adopting the above technical solution, the sliding groove is used to limit the sliding protrusion, thereby reducing the risk of the rotating plate driving the sliding plate to rotate together.

[0016] Optionally, the surface of the rotating blade facing the preparation tank is flat, and the thickness of the middle position of the rotating blade is greater than the thickness of at least one edge position.

[0017] By adopting the above technical solution, the carcass material gathered on the back of the rotating blade can slide off the rotating blade during the upward movement of the rotating blade, reducing the risk of the carcass material falling onto the workbench during the resetting of the feeding mechanism.

[0018] Optionally, the demolding mechanism includes a support plate and a linear drive component, the support plate is located in the preparation tank to form the bottom of the preparation tank, and the side wall of the support plate abuts against the tank wall of the preparation tank; the output end of the linear drive component is hinged to the bottom of the support plate, and the hinge point is located at the center position of the bottom surface of the support plate, and the linear drive component is used to drive the support plate to move vertically; the support plate includes a low-density part and a high-density part, and the low-density part and the high-density part are symmetrically arranged with the center line of the bottom surface of the support plate as the axis of symmetry.

[0019] By adopting the above technical solution, after the pressurization of the carcass sheet is completed, the linear drive component is started, and the linear drive component pushes out the pallet. Since the density distribution of the pallet is uneven and the pallet is hinged to the linear drive component and the limit surface is inclined, after the pallet is completely removed from the preparation tank, the pallet tilts, causing the carcass sheet to slide off the pallet, completing the demolding of the carcass sheet; then the pallet can be brought back into the preparation tank through the linear drive component.

[0020] Optionally, the lower edge of the support plate is arranged in an arc shape.

[0021] By adopting the above technical solution, a guiding role of movement is played during the resetting process of the support plate, so that the support plate can return to the preparation tank more smoothly.

[0022] Optionally, the workbench is provided with a conveyor belt, and the conveyor belt is used to receive the carcass sheets ejected from the preparation trough.

[0023] By adopting the above technical solution, the tire body sheets taken out from the preparation tank are transported to other workstations by means of a conveyor belt, so that the inspectors can carry out the next operation.

[0024] Optionally, the support plate is detachably connected to the linear drive member.

[0025] By adopting the above technical solution, it is convenient to replace the support plate according to the preparation requirements, and the flexibility of the demoulding mechanism is improved.

[0026] Optionally, the pressurizing mechanism further includes a second driving assembly, the pressurizing head is connected to the output end of the second driving assembly, and the pressurizing head and the second driving assembly are detachably connected.

[0027] By adopting the above technical solution, on the one hand, the pressure head with different numbers of forming protrusions can be replaced according to the required distribution density of diamonds; on the other hand, if the test block is finally formed by cold pressing, the flat pressure head can also be replaced for pressing.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The workbench is equipped with a preparation tank, a loading mechanism, a pressurizing mechanism, and a demolding mechanism. A molding protrusion is also provided on the pressurizing head to prepare the matrix sheet for making the test block. The matrix sheet has grooves for placing diamonds. The grooves limit the diamonds, ensuring their distribution and improving the uniformity of the matrix material's density distribution, thereby enhancing the test block's detection accuracy.

[0030] 2. The feeding mechanism is equipped with a rotating blade. During feeding, the rotating blade rotates to stir and smooth the carcass material dropped into the preparation trough, further improving the uniformity of the carcass material density distribution in the carcass sheet, thereby improving the detection accuracy of the test block;

[0031] 3. The support plate has a high-density part and a low-density part and is hinged to the linear drive member, so that the support plate tilts after completely pushing the carcass sheet out of the preparation groove.

[0045] Diamond cutting heads consist of a matrix material and diamond particles. During preparation, the diamond particles are distributed between adjacent layers of matrix material. After multiple layers are laid, they are pressed and / or sintered to form a block-shaped diamond cutting head. The matrix material is a powder, made from one or more of a single metal powder (copper powder, iron powder, nickel powder, zinc powder, etc.), a pre-alloyed powder (a metal powder composed of two or more single alloys, with the main elements including iron, nickel, copper, tin, etc.), or other materials, mixed according to a specific ratio and application requirements. When preparing and mixing the matrix material, it is usually necessary to first use the matrix material to make a test block, which is then tested to determine characteristics such as the matrix's grip and wear properties.

[0046] In order to improve the accuracy of the matrix material test data, the actual situation of the diamond bit is usually simulated in the test block, and some diamond particles are filled to further test the bonding performance of the diamond particles with the matrix material, the holding force of the matrix material and other performance conditions.

[0047] To improve the efficiency of matrix material formulation testing, test blocks are often prepared manually by first filling a layer of powdered matrix material into a tooling mold, then placing diamond particles on top of this layer, and then filling the tooling mold with a new layer of matrix material to form the test block. This preparation process is prone to problems such as multiple diamond particles being located in the same position on the matrix material and uneven matrix material layers, which in turn affect the accuracy of testing the test block for properties such as bonding performance and matrix material holding force.

[0048] Reference Figure 1 Therefore, the present application discloses a test block preparation device for composite granite tool bit matrix material testing, which is used to prepare a test block 1. The test block 1 includes a multi-layer matrix sheet 11. The matrix sheet 11 is press-formed using a powdered matrix material. The matrix sheet 11 has grooves 12 for placing diamond particles 13. When preparing the test block 1, the matrix sheet 11 is first formed, and then the diamond particles 13 are placed in the grooves 12. Thereafter, the diamond particles 13 and the matrix sheet 11 are sequentially stacked according to the test requirements. Finally, the test block 1 is formed by sintering or cold pressing.

[0049] The test block 1 is made using this device, and the preparation process is relatively simple. On the one hand, since the thickness of the single-layer carcass sheet 11 is relatively thin compared to the entire test block 1, the distribution of the carcass material in the carcass sheet 11 is relatively uniform, so that the distribution of the carcass material in the test block 1 formed by stacking multiple layers of carcass sheets 11 is relatively uniform, and thus the distribution of the carcass material around the diamond particles 13 is relatively uniform, which can more accurately test the holding force performance of the carcass material on the diamond particles 13. On the other hand, since the carcass sheet 11 has grooves 12, the diamond particles 13 can be placed at a certain position, that is, the distribution position of the diamond particles 13 in the carcass material can be artificially controlled, and the diamond particles 13 will not shift during the final molding process, which can more accurately simulate the distribution of the diamond particles 13 in the carcass material and form an effective combination between the diamond particles 13 and the carcass material. Therefore, the test effect and test accuracy of the carcass material can be better improved based on the test of the holding force, wear performance, etc. of the test block 1.

[0050] The following is combined with Figure 2-10 This application is described in further detail.

[0051] The present application embodiment discloses a test block preparation device for composite granite cutter head matrix material testing. Figure 2 and Figure 3The apparatus for preparing a test block 1 for composite granite tool bit matrix material testing includes a workbench 2, a preparation mold 3, a loading mechanism 4, a pressurizing mechanism 5, and a demolding mechanism 6. The preparation mold 3 has a preparation tank 31 for accommodating matrix sheet material 11. The loading mechanism 4 is used to fill the preparation tank 31 with matrix material. The pressurizing mechanism 5 is used to pressurize the matrix material in the preparation tank 31. The demolding mechanism 6 is used to remove the pressurized matrix sheet material 11 from the preparation tank 31.

[0052] In this embodiment, the preparation mold 3 is detachably connected to the workbench 2 to facilitate the preparation of carcass sheets 11 of different sizes or shapes. The detachable connection between the preparation mold 3 and the workbench 2 can be screwed or clamped.

[0053] Reference Figure 4 and Figure 5 The feeding mechanism 4 includes a material storage box 41, a first drive assembly 42, and a feed pipe 43. A feeding port 411 for feeding material is formed through the upper plate of the material storage box 41, and an opening and closing member 412 for opening and closing the feeding port 411 is threadedly connected to the feeding port 411. The material storage box 41 has a storage cavity 413 for accommodating carcass material, and the storage cavity 413 is connected to the feeding port 411. The feed pipe 43 is provided with an opening and closing assembly 44 for controlling the connection or isolation of the inner cavity of the feed pipe 43.

[0054] The first driving assembly 42 includes a first cylinder 421 and a second cylinder 422. The first cylinder 421 is connected to the workbench 2, and the second cylinder 422 is connected to the output end of the first cylinder 421. The first cylinder 421 is used to drive the second cylinder 422 to move horizontally to above the preparation tank 31. The storage box 41 is connected to the output end of the second cylinder 422, and the second cylinder 422 is used to drive the storage box 41 to move vertically.

[0055] The feed pipe 43 is connected to the lower part of the storage box 41. The lumen of the feed pipe 43 is connected to the storage chamber 413. The feed pipe 43 extends along the height direction of the storage box 41. The connection between the feed pipe 43 and the storage box 41 includes but is not limited to bonding, welding, bolt connection, clamping, etc.

[0056] A rotating motor 414 is fixed to the upper part of the storage box 41, and the output end of the rotating motor 414 is connected to the first rotating shaft 45, which extends into the storage cavity 413. The first rotating shaft 45 is slidably connected to the second rotating shaft 46 along its own length direction, and the second rotating shaft 46 passes through the lumen of the delivery pipe 43 and is coaxially arranged with the delivery pipe 43.

[0057] Reference Figure 5 and Figure 6The opening and closing assembly 44 includes a rotating plate 441 and a sliding plate 442. The rotating plate 441 is disposed around the circumference of the second rotating shaft 46. The outer wall of the rotating plate 441 is provided with an external thread 443. The inner wall of the feed pipe 43 is provided with an internal thread 432. The internal thread 432 is threadably engaged with the external thread 443, thereby threading the rotating plate 441 into the feed pipe 43. The sliding plate 442 is located above the rotating plate 441 and abuts against the rotating plate 441. The sliding plate 442 is slidably connected to the feed pipe 43 along the length of the feed pipe 43.

[0058] Reference Figure 6 and Figure 7 The rotating plate 441 is penetrated by a first through-hole 445 , and the sliding plate 442 is penetrated by a second through-hole 446 . When the first through-hole 445 is connected with the second through-hole 446 , the end of the material delivery pipe 43 away from the material storage box 41 is connected with the material storage cavity 413 .

[0059] Reference Figure 5 and Figure 8 A rotating blade 461 is provided at the end of the second rotating shaft 46 away from the rotating motor 414 .

[0060] Under normal circumstances, the first through-port 445 and the second through-port 446 are not connected. Therefore, the end of the feed pipe 43 is not connected to the material storage chamber 413, and the carcass material above the sliding plate 442 does not fall. During loading, the first drive assembly 42 is used to move the feed pipe 43 to the top of the preparation tank 31. Then, the rotary motor 414 is started. The rotary motor 414 drives the second rotating shaft 46 to rotate via the first rotating shaft 45. The second rotating shaft 46 drives the rotating plate 441 to rotate, so that the first through-port 445 and the second through-port 446 are intermittently connected, allowing the carcass material to fall into the preparation tank 31 through the first through-port 445 and the second through-port 446. At the same time, the rotating plate 441 drives the second rotating shaft 46 to move in the direction close to the preparation tank 31 under the cooperation of the internal thread 432 and the external thread 443, and the second rotating shaft 46 drives the rotating blade 461 to rotate, that is, the rotating blade 461 moves toward the preparation tank 31 while rotating; the rotating blade 461 gradually moves to the bottom of the preparation tank 31, and stirs the carcass material in the preparation tank 31 during the movement, on the one hand improving the mixing uniformity of the carcass material, and on the other hand smoothing the carcass material in the preparation tank 31 to a certain extent; thereby, on the one hand, the carcass material with multiple components is mixed more evenly in the preparation tank 31 by stirring, and on the other hand, the carcass material in the preparation tank 31 is distributed more evenly by smoothing, thereby improving the density uniformity and distribution uniformity of the carcass material in the test block 1, so as to achieve the test of the holding force, wear performance, etc. of the test block 1, improve the test effect of the carcass material and improve the test accuracy.

[0061] Finally, the rotating motor 414 drives the first rotating shaft 45 to rotate in the opposite direction, driving the rotating blade 461, the rotating plate 441 and the sliding plate 442 to move upward and reset. During the upward movement of the rotating blade 461, the carcass material in the preparation tank 31 is stirred and smoothed for the second time, further improving and strengthening the above effect.

[0062] Specifically, in this embodiment, the cross-section of the end position of the second rotating shaft 46 is hexagonal, and the first rotating shaft 45 has a cavity for the second rotating shaft 46 to pass through. While realizing the sliding connection between the second rotating shaft 46 and the first rotating shaft 45, the first rotating shaft 45 rotates and drives the second rotating shaft 46 to rotate together.

[0063] In other embodiments, the cross-section of the end portion of the second rotating shaft 46 may also be in other shapes, such as a star shape, a triangle shape, etc.

[0064] Reference Figure 7 The structure of the sliding connection between the sliding plate 442 and the conveying pipe 43 is as follows: a sliding protrusion 444 is provided on the peripheral side of the sliding plate 442, and a sliding groove 433 is opened on the inner wall of the conveying pipe 43 along its own length direction. The sliding groove 433 is used for connection with the sliding protrusion 444, so that the sliding groove 433 is used to limit the sliding protrusion 444, thereby reducing the risk of the rotating plate 441 driving the sliding plate 442 to rotate together.

[0065] Reference Figure 8 The surface of the rotating blade 461 facing the preparation tank 31 is flat, and the thickness of the central portion of the rotating blade 461 is greater than the thickness of at least one edge portion. This allows the carcass material accumulated on the back of the rotating blade 461 to slide off the rotating blade 461 during its upward movement, thereby reducing the risk of the carcass material falling onto the workbench 2 during the resetting of the feeding mechanism 4.

[0066] In this embodiment, the cross section of the rotating blade 461 perpendicular to its own axis is an isosceles triangle. In other embodiments, the cross section can also be other triangles, or the rotating blade 461 can also be arranged in an arc shape.

[0067] Reference Figure 5Furthermore, in this embodiment, the upper surface of the preparation mold 3 is inclined to form a limiting surface 32. The distance between the limiting surface 32 and the workbench 2 gradually decreases from the side close to the preparation tank 31 to the other side. The end of the feeding pipe 43 is connected to a cover 434. The cover 434 has four abutting surfaces 431. When the end of the feeding pipe 43 abuts the preparation mold 3, the four abutting surfaces 431 respectively abut the four limiting surfaces 32. Therefore, the abutment between the abutting surfaces 431 and the limiting surfaces 32 makes the feeding pipe 43 more stable when abutting the preparation mold 3. At the same time, a closed space is formed to reduce the risk of the carcass material falling onto the workbench 2 during the loading process.

[0068] In addition, in this embodiment, the stirring blade 462 is connected to the second rotating shaft 46, and the stirring blade 462 is located in the storage chamber 413, so that the tire material in the storage chamber 413 is stirred during the rotation of the second rotating shaft 46, thereby improving the uniformity of the tire material.

[0069] In addition, it is worth noting that, for ease of display, the drawings of this application only show a case where one feed pipe 43 is provided. In actual applications, multiple feed pipes 43 may be provided according to the ratio of the length and width of the preparation tank 31, and then multiple rotating blades 461 may be provided to effectively stir and smooth the carcass material in the preparation tank 31; and the inner diameters of the multiple feed pipes 43 may be different to correspond to the setting of rotating blades 461 of different sizes.

[0070] Reference Figure 1 and Figure 9 The pressurizing mechanism 5 includes a second driving assembly 51 and a pressurizing head 52. The second driving assembly 51 includes a third cylinder 511 and a fourth cylinder 512. The third cylinder 511 is connected to the workbench 2, and the fourth cylinder 512 is connected to the output end of the third cylinder 511. The third cylinder 511 is used to drive the fourth cylinder 512 to move horizontally to above the preparation tank 31. The pressurizing head 52 is connected to the output end of the fourth cylinder 512, and the fourth cylinder 512 is used to drive the pressurizing head 52 to move vertically.

[0071] In this embodiment, the pressure head 52 and the fourth cylinder 512 are detachably connected to facilitate replacement of different pressure heads 52 according to different test requirements. The detachable connection methods include but are not limited to bolt connection, clamping connection, threaded connection, etc.

[0072] In this embodiment, the surface of the pressing head 52 facing the preparation groove 31 is provided with a molding protrusion 521 to facilitate forming the groove 12 for placing the diamond 13 in the carcass sheet 11. In this embodiment, the molding protrusion 521 and the pressing head 52 are integrally formed.

[0073] It is understandable that the surface of the pressure head 52 facing the preparation tank 31 may also be a plane, so as to be used for preparing a carcass sheet 11 or an integral test block 1 with a smooth surface.

[0074] Reference Figure 2 and Figure 10 The demolding mechanism 6 includes a support plate 61 and a linear drive member 62. The support plate 61 is located in the preparation tank 31 to form the bottom of the preparation tank 31. The side wall of the support plate 61 abuts against the wall of the preparation tank 31. The output end of the linear drive member 62 is hinged to the bottom of the support plate 61, and the hinge point is located at the center of the bottom surface of the support plate 61. The linear drive member 62 is used to drive the support plate 61 to move vertically. The support plate 61 includes a low-density portion 611 and a high-density portion 612. The low-density portion 611 and the high-density portion 612 are symmetrically arranged with the center line of the bottom surface of the support plate 61 as the symmetry axis, and the low-density portion 611 and the high-density portion 612 have the same volume. With this design, after the carcass sheet 11 is pressurized, the linear drive 62 is started, and the linear drive 62 pushes out the support plate 61. Since the density distribution of the support plate 61 is uneven and the support plate 61 is hinged to the linear drive 62 and the limiting surface 32 is tilted, after the support plate 61 is completely removed from the preparation tank 31, the support plate 61 tilts, causing the carcass sheet 11 to slide off the support plate 61, completing the automatic demolding of the carcass sheet 11; then the support plate 61 can be brought back into the preparation tank 31 through the linear drive 62.

[0075] It can be understood that in order to achieve the purpose of tilting the support plate toward the high-density portion 612, when the diamond particles 13 in the prepared test block 1 are distributed asymmetrically, attention should be paid to the position of the forming protrusion 521 when installing the pressure head 52, so that the part with higher density of the carcass sheet 11 formed after the pressure head 52 is pressurized is located at the position of the high-density portion 612.

[0076] It is understandable that the lower surface of the preparation mold 3 is integrally formed with an abutment portion 33, and the abutment portion 33 is used for abutting the lower surface of the support plate 61 to ensure the stability of the support plate 61 during the pressurization process.

[0077] Furthermore, the lower edge of the support plate 61 is arranged in an arc shape, thereby playing a guiding role in the movement during the return process of the support plate 61, so that the support plate 61 can return to the preparation tank 31 more smoothly.

[0078] Reference Figure 1 and Figure 2 Furthermore, the workbench 2 is provided with a conveyor belt 7, which is used to receive the carcass sheet 11 that slides off the support plate 61. A placement table 8 is provided at the end of the conveyor belt 7 away from the preparation mold 3. The carcass material is transported to the placement table 8 by the conveyor belt 7, which is convenient for the inspection personnel to perform subsequent operations.

[0079] In another feasible embodiment, the output end of the fourth driving member is rotatably connected to a rotating member, and the pressure head is fixedly or detachably connected to the rotating member, and there are multiple pressure heads, among which there is at least one pressure head with a molded protrusion and at least one flat pressure head, and the pressure head facing the preparation tank is replaced by rotating the rotating member.

[0080] The implementation principle of the test block 1 preparation device for composite granite tool head matrix material testing according to the embodiment of the present application is as follows: when preparing the test block 1, first start the first drive assembly 42, use the first drive assembly 42 to drive the feed pipe 43 to move to the top of the preparation tank 31, and make the four abutment surfaces 431 respectively abut against the four limit surfaces 32. Then start the rotary motor 414, use the rotary motor 414 to drive the rotary blade 461 to rotate forward and move downward, and then rotate reverse and move upward, and on the other hand, make the first through port 445 and the second through port 446 in an intermittently connected state, so that the matrix material falls into the preparation tank 31, and the rotary blade 461 stirs and smoothes the matrix material falling into the preparation tank 31; after the loading is completed, the loading mechanism 4 is reset, and the second drive assembly 51 is started, and the second drive assembly 51 drives the pressure head 52 to move To the top of the preparation tank 31 and pressurize the carcass material in the preparation tank 31 to form a carcass sheet 11; then the pressurizing mechanism 5 is reset, and the linear drive 62 is started, and the linear drive 62 is used to push the support plate 61 out of the preparation tank 31, thereby pushing out the carcass sheet 11 in the preparation tank 31. Since the density distribution of the support plate 61 is uneven and it is hinged to the linear drive 62, the support plate 61 is completely pushed out of the preparation tank 31 and then tilted, and the carcass sheet 11 on the support plate 61 slides to the conveyor belt 7 and is transported to the placement table 8 by the conveyor belt 7.

[0081] The tester places diamond particles 13 in the grooves 12 of the carcass sheet 11. The carcass sheet 11 and diamond particles 13 are then stacked on top of the carcass sheet 11 in sequence, depending on the test requirements. Finally, the carcass sheet 11 and diamond particles 13 are pressed or sintered to form the test block 1. If the test block 1 is made by cold pressing, the stacked carcass sheet 11 and diamond particles 13 are placed back into the preparation groove 31, and the pressing head 52 with the formed protrusions 521 is replaced with a flat pressing head 52 for pressurization.

[0082] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
