[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0030] The present application provides an oilstone prefabrication device, including: a briquetting machine 100, used to prepare an oilstone substrate; a sintering furnace 200, used to sinter the oilstone substrate into a dense block; and a dry cutter 300, used to cut the dense block into a basic semi-finished product.

[0031] The powder used to prepare the oilstone is pressed into an oilstone substrate of the desired shape in the briquetting machine 100, and then sintered at high temperature by an open flame to achieve crystal bonding, volume shrinkage and density increase of the oilstone substrate to obtain a dense block. Finally, the dense block is cut into basic semi-finished products of the desired size by a dry cutter 300.

[0032] In order to facilitate the rapid transfer of production materials, the oilstone prefabrication equipment provided in the present application also includes a transfer mechanism, which is used to transfer the oilstone substrate to the sintering furnace 200 and to transfer the dense material block to the dry cutting machine 300.

[0033] The briquetting machine 100 includes: a material pressing mechanism 110 for pressing powder into an oilstone base material;

[0034] The material pushing mechanism 120 is used to push the oilstone substrate pressed by the material pressing mechanism 110 to the downstream; the transfer mechanism includes a material receiving fixture 410, and the material receiving fixture 410 is used to receive the oilstone substrate.

[0035] For details, please refer to Figure 1 In the illustrated embodiment, the pushing mechanism 120 is arranged on the left side of the pressing mechanism 110, and the material receiving fixture 410 is arranged on the right side of the pressing mechanism 110; after the pressing mechanism 110 produces the oilstone substrate, the pushing mechanism 120 can move from left to right and push the oilstone substrate into the material receiving fixture 410.

[0036] Specifically, the material receiving jig 410 includes: a material plate 411, which is used to receive the oilstone substrate. The material plate 411 is provided with a limit groove, and the limit groove is extended along the pushing direction of the pushing mechanism 120. The pushing mechanism 120 can push the oilstone substrate into the limit groove; a baffle 412, which is slidably arranged in the limit groove. After the pushing mechanism 120 pushes the oilstone substrate into the limit groove, the oilstone substrate can abut against the baffle 412. As the pushing mechanism 120 continuously pushes the oilstone substrate into the limit groove, the baffle 412 continuously moves in the direction away from the pushing mechanism 120, so that the oilstone substrates are arranged in a row in the material receiving jig 410.

[0037] It is easy to imagine that the limiting groove can be a straight groove formed by a depression on the surface of the material plate 411, or it can be a groove-shaped channel extending in a straight line formed by two groups of protrusion structures on the surface of the material plate 411.

[0038] Continue to refer to Figure 1 In the illustrated embodiment, the material plate 411 and the material pushing mechanism 120 are arranged opposite to each other, and the material pressing mechanism 110 is arranged between the two. The material pushing mechanism 120 is directly opposite to the oilstone substrate and the limiting groove, and the material pushing mechanism 120 can push the oilstone substrate into the limiting groove. After the oilstone substrate enters the limiting groove, it will contact the baffle 412.

[0039] In a specific embodiment, in the initial state, there is no oilstone substrate in the material receiving jig 410, and the baffle 412 is located at the entrance of the limiting groove near the pushing mechanism 120; after the pressing mechanism 110 produces the first oilstone substrate, the pushing mechanism 120 pushes the first oilstone substrate toward the material receiving jig 410, and the first oilstone substrate can push away the baffle 412 and enter the limiting groove. The pushing mechanism 120 is reset, and the pressing mechanism 110 suppresses the second oilstone substrate; the pushing mechanism 120 works again and pushes the second oilstone substrate toward the material receiving jig 410, and the second oilstone substrate can contact and push the first oilstone substrate, and the baffle 412 moves away from the pushing mechanism 120 again, and the second oilstone substrate enters the limiting groove... and so on, the material receiving jig 410 can receive multiple oilstones. In the material receiving jig 410, multiple oilstones are arranged in parallel and in rows.

[0040] The limiting groove is provided to limit the arrangement position of the oilstone substrate, limit the two sides of the oilstone substrate, unify the arrangement state of the oilstone substrate, and avoid lateral displacement of the oilstone substrate; a baffle 412 is provided, and the baffle 412 can cooperate with the limiting groove to limit the oilstone substrate from three sides, so as to further calibrate the arrangement state of the oilstone substrate; at the same time, the oilstone substrate pushed out by the pushing mechanism 120 is abutted against the baffle 412, and the oilstone substrate will not fall over when subjected to force displacement, so as to better ensure the material receiving stability and accuracy of the material receiving fixture 410.

[0041] After a batch of oilstone substrates are pressed, or a receiving jig 410 is fully loaded, the receiving jig 410 is transferred from the briquetting machine 100 to the sintering furnace 200; the oilstone substrates received by the receiving jig 410 are arranged in a uniform posture in the receiving jig 410, which is very convenient for workers or mechanical equipment (such as manipulators, robots, etc.) to take the oilstone substrates.

[0042] Furthermore, the sintering furnace 200 includes: a material rack 210 for loading the oilstone substrate to be sintered; a furnace chamber 220 for providing space for the sintering of the oilstone substrate; after sintering is completed, the empty material receiving fixture 410 is used to receive the dense material block; the transfer mechanism also includes a storage rack 420, which is used to place the material receiving fixture 410 to facilitate the storage of the oilstone substrate and the dense material block.

[0043] To improve production efficiency, the furnace chamber 220 has a larger volume and sintering space. For this purpose, the material rack 210 can be set to a multi-layer structure to fully utilize the sintering space. The oilstone substrates are arranged in an array in the material rack 210 at intervals so that the oilstone substrates can be baked at high temperature.

[0044] The sintering of the oilstone substrate needs to last for a period of time. During the continuous production process, when a batch of oilstone substrates are sintered in the furnace chamber 220 , the newly pressed oilstone substrates can be received by the receiving fixture 410 and stored in the storage rack 420 .

[0045] After the sintering furnace 200 completes the sintering of a batch of oilstone substrates, workers or mechanical equipment can directly transfer the dense material blocks to the storage rack 420, or they can first place the dense material blocks in the receiving jig 410, and then place the receiving jig 410 carrying the dense material blocks into the storage rack 420, waiting for the dry cutting machine 300 to need them.

[0046] For details, please refer to Figure 1 In the illustrated embodiment, a plurality of groups of storage racks 420 are provided on one side of the sintering furnace 200, and any group of storage racks 420 is set to a multi-layer structure so as to store as many materials as possible. Among them, some storage racks 420 are used to store material receiving jigs 410 carrying oilstone substrates, some storage racks 420 are used to store material receiving jigs 410 carrying dense material blocks, and some storage racks 420 are used to store empty material receiving jigs 410. When the material receiving jig 410 is lacking at a certain stage of the production line (such as the briquetting machine 100 needs a new material receiving jig 410 to receive the oilstone substrate), or when there are more material receiving jigs 410 at a certain stage of the production line (such as the material receiving jig 410 is empty after the dry cutting machine 300 takes away the dense material block), the material receiving jig 410 can be provided or stored by the storage rack 420.

[0047] Furthermore, the dry cutting machine 300 includes: a machine platform 310, on which a cutting station is provided; a cutter 320, for cutting the dense material block located at the cutting station; the transfer mechanism also includes a material picking component 430, and the material picking component 430 is used to release the dense material block in the material receiving fixture 410 to facilitate the dense material block to enter the cutting station.

[0048] Due to the limitation of the structure of the receiving jig 410, the dense material blocks are also arranged in the receiving jig 410 in a side-by-side or column manner. Before cutting, the dense material blocks are released by the material taking component 430, and the dense material blocks can leave the receiving jig 410 and enter the cutting station; after being cut by the cutter 320, the dense material blocks can be cut into basic semi-finished products with the required size.

[0049] The material taking component 430 may be a suction cup, a clamp or the like that can grab the dense material block and then take the dense material block out of the material receiving fixture 410. It may also be a displacement that can push the baffle 412 to move the baffle 412 toward the entrance of the limiting groove and then push the dense material block out of the material receiving fixture 410.

[0050] By setting up a transfer mechanism and using the material receiving fixture 410 in cooperation with the material pushing mechanism 120, the oilstone substrate can be quickly and reliably received, and the oilstone substrate can be arranged in a uniform posture in a row, which is convenient for the sintering furnace 200 to use; the material receiving fixture 410, the oilstone substrate, and the dense material blocks are stored in the storage rack 420, which can match the operating rhythm of the briquetting machine 100, the sintering furnace 200 and the dry cutting machine 300 to ensure the continuity and circulation of production; the material receiving fixture 410 is used in cooperation with the material taking component 430 to quickly release the dense material blocks, and further cooperate with the dry cutting machine 300 to quickly and continuously prepare basic semi-finished products.

[0051] Optionally, the transfer mechanism further includes a conveying component, which is capable of receiving the material receiving jig 410 and transferring the material receiving jig 410 between the briquetting machine 100 and the sintering furnace 200 , and between the sintering furnace 200 and the dry cutting machine 300 .

[0052] Among them, the transmission components can adopt automated transmission equipment such as AGV carts and rail cars, or directional transmission equipment such as conveyor belts and motorized rollers, or intelligent transmission equipment such as manipulators and robots.

[0053] Specifically, in the briquetting machine 100, after a set of receiving jigs 410 are loaded with the oilstone substrate, the conveying assembly can receive and send the set of receiving jigs 410 into the sintering furnace 200 or the storage rack 420; before sintering, the oilstone substrate in the receiving jigs 410 is taken out and arranged on the rack 210; after the receiving jigs 410 are empty, they can be put back into the storage rack 420, or they can be sent into the briquetting machine 100 by the conveying assembly to receive the newly prepared oilstone substrate; After sintering is completed, the dense material blocks are placed in the receiving jig 410; after the receiving jig 410 is loaded with the dense material blocks, the conveying component can receive and send the group of receiving jigs 410 into the dry cutting machine 300; after the pushing mechanism 120 releases all the dense material blocks in the receiving jig 410, the receiving jig 410 is empty and can be placed back into the storage rack 420 through the conveying component, or sent into the briquetting machine 100 through the conveying component to receive the newly prepared oilstone substrate.

[0054] In one embodiment, the material pressing mechanism 110 includes: a material table 111, on which a material trough is provided, and the material trough is used to receive powder; a pressing block 112, which is provided above the material trough; and a material pressing driving member 113, which is used to drive the pressing block 112 to move in a vertical direction so that the pressing block 112 can compact the powder in the material trough, thereby constructing an oilstone substrate in the material trough.

[0055] For details, please refer to Figure 2In the illustrated embodiment, a square material trough is provided on the material platform 111, and the shape of the pressing block 112 is adapted to the material trough and is also arranged in a square shape; the pressing driving member 113 can be any driving member that is convenient to drive the pressing block 112 to press the powder material, such as a cylinder or an electric cylinder. After the material trough is filled with powder material, the pressing driving member 113 drives the pressing block 112 to move from top to bottom, and the pressing block 112 penetrates into the material trough, can compact the powder material, and press the powder material into a square block of oilstone substrate.

[0056] Furthermore, the briquetting machine 100 also includes a feeding mechanism 130, and the feeding mechanism 130 is used to convey powder to the material trough.

[0057] The feeding mechanism 130 may be any structure such as a hopper, a material frame, a pipeline, etc. that is convenient for connecting to the material trough and conveying powder to the material trough.

[0058] The feeding mechanism 130 has a certain volume, and the feeding mechanism 130 can also store powder.

[0059] In one embodiment, the feeding mechanism 130 includes a material tank and a conveying pipe. The material tank is used to store powder. The output end of the material tank is provided with a conveying pipe so that the conveying pipe is connected to the material trough. The powder in the material tank can pass through the conveying pipe and be filled into the material trough.

[0060] Optionally, a valve is further provided at the output end of the material tank; when the valve is opened, the powder can flow into the conveying pipeline; when the valve is closed, the feeding mechanism 130 stops outputting the powder.

[0061] Optionally, the valve adopts a quantitative valve; when the quantitative valve is opened, the powder can pass through the material tank and flow into the material trough; when the powder flows out for a preset time or the outflow of the powder reaches a preset value, the quantitative valve is closed, thereby realizing quantitative material collection in the material trough.

[0062] Furthermore, the briquetting machine 100 further comprises a pushing mechanism 140 , which is used to push the oilstone substrate out of the trough, so that the pushing mechanism 120 can push the oilstone substrate.

[0063] In one embodiment, the material lifting mechanism 140 includes: a lifting plate 141, which is arranged in the material trough; and a lifting driving member 142, which is used to drive the lifting plate 141 to move in a vertical direction so that the lifting plate 141 can lift the oilstone substrate.

[0064] The lifting drive member 142 may be any driving structure that is convenient for driving the top plate 141 to move up and down, such as a cylinder or an electric cylinder.

[0065] In one embodiment, the pushing mechanism 120 includes: a pushing plate 121 for pushing the oilstone substrate; and a pushing driving member 122 for driving the pushing plate 121 to translate.

[0066] The push drive member 122 may be any drive structure such as a pneumatic cylinder or an electric cylinder that can conveniently drive the push plate 121 to translate toward the material trough and the material receiving fixture 410 .

[0067] For details, please refer to Figure 2 In the illustrated embodiment, the material pushing mechanism 140 is arranged below the material platform 111, and the top plate 141 constitutes the bottom of the material trough; the feeding mechanism 130 and the material pushing mechanism 120 are arranged on the left side of the material platform 111, and the material receiving fixture 410 is arranged on the right side of the material platform 111. After the feeding mechanism 130 puts the powder into the material trough, the material pressing driving component 113 drives the pressing block 112 to descend, probe into the material trough, and press the powder into an oilstone base material; after the material pressing driving component 113 drives the pressing block 112 to rise and move away from the material trough, the lifting driving component 142 drives the top plate 141 to rise and push the oilstone base material away from the material trough; the pushing driving component 122 drives the pushing plate 121 to move from left to right, and the pushing plate 121 can push the oilstone base material on the top plate 141 into the material receiving fixture 410; the lifting driving component 142 drives the top plate 141 to descend, and the material trough can receive the powder; the pushing driving component 122 drives the pushing plate 121 to move from right to left, and the pushing plate 121 returns to the left side of the material trough to wait for the next round of pushing.

[0068] To prevent the push plate 121 from interfering with the feeding mechanism 130 in feeding powder into the material trough, in one embodiment, after the push plate 121 pushes the oilstone substrate away from the material trough, the feeding mechanism 130 feeds the material into the material trough; after the feeding is completed, the push drive 122 drives the push plate 121 to return to its original position.

[0069] In another embodiment, the push plate 121 is arranged on the side of the feeding mechanism 130 facing the material trough, and the pushing driving member 122 can drive the push plate 121 and the feeding mechanism 130 to translate synchronously; when working, the ejecting mechanism 140 ejects the oilstone substrate out of the material trough, and the pushing driving member 122 drives the push plate 121 and the feeding mechanism 130 to move toward the material trough, and the push plate 121 first contacts the oilstone substrate, pushes the oilstone substrate away from the material trough, and pushes it toward the material receiving fixture 410, the material trough is empty, and the feeding mechanism 130 connects to the material trough and feeds the material.

[0070] For details, please refer to Figure 2 In the illustrated embodiment, the push plate 121 is fixedly arranged on the right side of the discharge end of the feeding mechanism 130; the push drive member 122 is connected to the feeding mechanism 130 and is used to drive the feeding mechanism 130 to move horizontally in the left and right directions. After the top plate 141 lifts up the oilstone substrate, the push drive member 122 drives the feeding mechanism 130 and the push plate 121 to move from left to right. The push plate 121 is in front and contacts the oilstone substrate first, and can push the oilstone substrate away from the material trough; after the oilstone substrate is pushed away, the top plate 141 descends and the material trough is restored; as the push plate 121 continues to move to the right, the discharge end of the feeding mechanism 130 moves to align with the material trough. At this time, the feeding mechanism 130 puts in powder, and the powder can fill the material trough.

[0071] Optionally, the push drive member 122 can drive the push plate 121 and the feeding mechanism 130 to move back and forth.

[0072] Continue to refer to Figure 2 In the illustrated embodiment, the push drive 122 can drive the push plate 121 and the feeding mechanism 130 to reciprocate in the left-right direction. Specifically, the push drive 122 drives the push plate 121 and the feeding mechanism 130 to move rightward by a preset stroke, the oilstone substrate is pushed into the receiving fixture 410, and the discharge end of the feeding mechanism 130 moves from the left end of the material trough to the right end of the material trough; the push drive 122 drives the push plate 121 and the feeding mechanism 130 to move leftward by a preset stroke, the discharge end of the feeding mechanism 130 moves from the right end of the material trough to the left end of the material trough, and the push plate 121 passes along the top surface of the material trough; as the push drive 122 continuously drives the push plate 121 and the feeding mechanism 130 to reciprocate in the left-right direction, the feeding mechanism 130 can repeatedly spread the material to the material trough layer by layer, and when the material level is higher than the top surface of the material trough, the push plate 121 can smooth the material level to avoid the material level being too high.

[0073] In one embodiment, the feeding mechanism 130 includes: an inlet hopper 131 for receiving powder; a first agitator 134, which is arranged in the inlet hopper 131 and is used for mixing the powder for the first time; a material pipe 132, one end of which is connected to the inlet hopper 131; a second agitator 135, which is arranged in the material pipe 132 and is used for mixing the powder for the second time; and a discharge hopper 133, the other end of which is connected to the discharge hopper 133, and the powder can flow to the material trough through the discharge hopper 133.

[0074] For details, please refer to Figure 2 In the illustrated embodiment, the feeding mechanism 130 is arranged on the left side of the pressing mechanism 110; the feeding hopper 131 is arranged on the upper left side of the material trough, and the feeding hopper 131 has a certain volume and can store powder. The first agitator 134 includes a stirring blade and a stirring driving member, and the stirring driving member can be a rotating driving member such as a motor. The stirring blade is arranged in the feeding hopper 131, and the stirring driving member is used to drive the stirring blade to rotate; the stirring blade can stir the powder in the feeding hopper 131, thereby promoting the mixing of the powder.

[0075] Continue to refer to Figure 2 In the illustrated embodiment, the material pipe 132 is disposed below the material inlet hopper 131, and extends obliquely to the right from top to bottom, and is connected to the material outlet hopper 133. A second stirrer 135 is disposed in the material pipe 132, and the second stirrer 135 also includes a stirring blade and a stirring driving member; the second stirrer 135 and the material pipe 132 form a stirring cage, and the operation of the second stirrer 135 can not only further stir the powder and promote the mixing of the powder, but also promote the powder in the material pipe 132 to flow to the material outlet hopper 133, and play a role of spiral feeding.

[0076] In addition, the second agitator 135 can also play a role in quantitative feeding. Specifically, when the second agitator 135 is working, the stirring blades rotate, which can promote the spiral feeding of the powder in the material pipe 132 to the discharge hopper 133; after the stirring blades rotate for a preset time, or a preset amount of powder is fed, the second agitator 135 stops working, and the powder output of the feeding mechanism 130 is stopped, so that the quantitative feeding of the material trough is realized.

[0077] In one embodiment, the material receiving jig 410 also includes a first limit member 413 and a second limit member 414, the first limit member 413 and the second limit member 414 are spaced apart on the material plate 411, and a limit groove is formed between the first limit member 413 and the second limit member 414; wherein the spacing between the first limit member 413 and the second limit member 414 is adjustable to facilitate the material receiving jig 410 to receive oilstone substrates of different sizes.

[0078] The oilstone is used to grind parts. According to the specifications of the parts and the shape of the parts to be grinded, the oilstone needs to be prepared in different sizes. Generally, multiple briquetting machines 100 are arranged on the production line to press oilstone substrates of different sizes. In order to improve the applicability of the material receiving fixture 410, the slot width of the limit slot is made adjustable.

[0079] The first stopper 413 and the second stopper 414 can be any structure that is convenient for forming the groove wall and the stopper oilstone (which can be an oilstone substrate, a dense material block, or a basic semi-finished product) such as a plate, a block, or a rod. This reduces the distance between the first stopper 413 and the second stopper 414, reduces the groove width of the stopper groove, and allows the stopper groove to limit oilstones of small size; increases the distance between the first stopper 413 and the second stopper 414, increases the groove width of the stopper groove, and allows the stopper groove to limit oilstones of large size.

[0080] In one embodiment, referring to Figure 3 The first stopper 413 and the second stopper 414 are both U-shaped and can be inserted on both sides of the material plate 411. In this embodiment, the material plate 411 of different widths is replaced, and the first stopper 413 is inserted on the left side of the material plate 411 and the second stopper 414 is inserted on the right side of the material plate 411, so that the material receiving fixture 410 can be easily assembled.

[0081] In another embodiment, referring to Figure 4 and Figure 5, a first fixing plate 417 is provided on the left side of the material plate 411, and a first stopper 413 is elastically arranged on the first fixing plate 417 by a spring; a second fixing plate 418 is provided on the right side of the material plate 411, and a second stopper 414 is elastically arranged on the second fixing plate 418 by a spring; the first stopper 413 and the second stopper 414 are arranged opposite to each other along the left and right directions. In this embodiment, when oilstones of different widths are pushed between the first stopper 413 and the second stopper 414, the deformation degree of the spring is different; the spring can adapt to oilstones of different widths by compression deformation; at the same time, the spring has a tendency to return to its original state after deformation, and the elasticity generated by its deformation can act in reverse on the first stopper 413 and the second stopper 414, thereby prompting the first stopper 413 and the second stopper 414 to clamp the oilstone.

[0082] Optionally, the upper end of the limit groove is its entrance; the upper end of the first limit piece 413, the surface facing the second limit piece 414, is set as an inclined surface tilted from top to bottom to the right; the upper end of the second limit piece 414, the surface facing the first limit piece 413, is set as an inclined surface tilted from top to bottom to the left; the inclined surface of the first limit piece 413 and the inclined surface of the second limit piece 414 are inclined towards each other, so that the entrance of the limit groove is set in a gradually shrinking trumpet shape. In this way, it is convenient for oilstones of different sizes to enter and finally be clamped between the first limit piece 413 and the second limit piece 414.

[0083] Optionally, refer to Figure 4 A third fixing plate 419 is provided on the lower side of the material plate 411, and the baffle 412 is elastically arranged on the third fixing plate 419 by a spring. The spring gives a certain resistance to the baffle 412, which can prevent the baffle 412 from moving along the limit groove without the pressure of the oilstone, and further ensure that the baffle 412 can stably abut against the oilstone.

[0084] It should be added that the elastic force of the spring connected to the baffle 412 is relatively small. After the oilstone enters the limiting groove and abuts against the baffle 412, the spring can remain in a compressed state, thereby preventing the receiving fixture 410 from actively expelling the oilstone.

[0085] Optionally, refer to Figure 5 The material plate 411 is also provided with a guide limit groove, which is located between the first limit piece 413 and the second limit piece 414 and extends in the same direction as the limit groove; the bottom end of the baffle 412 is provided with a guide protrusion, which is slidably arranged in the guide limit groove; the guide limit groove can not only limit the installation position of the baffle 412, but also limit the moving direction of the baffle 412. The guide limit groove can also reduce the contact area between the oilstone and the material plate 411, reduce friction, and alleviate wear.

[0086] In another embodiment, the first limit member 413 and the second limit member 414 both include: a guide rod 413a, extending along the first direction; a first clamping block 413b, arranged at one end of the guide rod 413a; a second clamping block 413c, arranged at the other end of the guide rod 413a; the material plate 411 can be inserted between the first clamping block 413b and the second clamping block 413c; the first limit member 413 and the second limit member 414 are spaced apart along the second direction, and the second direction is horizontally perpendicular to the first direction.

[0087] For details, please refer to Figure 6 In the illustrated embodiment, the first direction is the up-down direction, and the second direction is the left-right direction. The guide rod 413a is extended in the up-down direction, and two guide rods 413a are spaced apart in the left-right direction, and the limit groove is between the two guide rods 413a.

[0088] Combined with reference Figure 7 The first clamping block 413b and the second clamping block 413c are both arranged in an L shape, and the first clamping block 413b and the second clamping block 413c are arranged symmetrically; the distance between the first clamping block 413b and the second clamping block 413c is adapted to the length of the material plate 411, and after the material plate 411 is inserted between the first clamping block 413b and the second clamping block 413c, the three can be tightly matched, and the first clamping block 413b and the second clamping block 413c can hold the two ends of the material plate 411. By holding the first clamping block 413b and the second clamping block 413c at different positions of the material plate 411, the distance between the two guide rods 413a can be changed.

[0089] Optionally, the baffle 412 is sleeved on one of the guide rods 413a, and a rubber ring 415 is provided between the baffle 412 and the guide rod 413a, and the rubber ring 415 is used to increase the damping between the baffle 412 and the guide rod 413a, so that the baffle 412 can stably abut against the oilstone substrate placed in the limiting groove.

[0090] For details, please refer to Figure 6 In the illustrated embodiment, the baffle 412 is sleeved on the left guide rod 413a, and a rubber ring 415 is provided between the baffle 412 and the guide rod 413a. Limited by the guide rod 413a, the baffle 412 can only move in the up and down directions along the limit groove. At the same time, due to the large friction between the rubber ring 415 and the guide rod 413a, under the influence of the rubber ring 415, when not pushed by external force, the baffle 412 will not actively move along the limit groove; thus, it can be ensured that the baffle 412 remains against the oilstone.

[0091] Optionally, the material receiving jig 410 also includes a guardrail 416. A socket 411a is provided at one end of the material plate 411. The guardrail 416 can be inserted into the socket 411a to block the entrance of the limiting groove. After the material receiving jig 410 loads the oilstone substrate, the guardrail 416 is inserted into the socket 411a. The guardrail 416 cooperates with the baffle 412 to fix the oilstone substrate in the limiting groove.

[0092] For details, please refer to Figure 6 In the illustrated embodiment, the upper end of the limit groove is its entrance. A plug hole 411a is provided between the upper portion of the material plate 411 and the first limit member 413 and the second limit member 414. Figure 7 After the receiving jig 410 is loaded with the oilstone, the fence 416 is inserted into the insertion hole 411a. At this time, the right side of the oilstone group is blocked by the baffle 412, the left side is blocked by the fence 416, and the front and rear sides perpendicular to the paper surface are blocked by the limiting groove walls (that is, the two guide rods 413a in the figure); that is to say, the four sides of the oilstone group are restricted, so that the oilstone is not easy to separate from the receiving jig 410, so that the receiving jig 410 can be transferred with the oilstone.

[0093] Optionally, the furnace chamber 220 is made of refractory bricks. Refractory bricks are made of refractory materials (such as silica bricks, clay bricks, etc.), which not only have excellent heat resistance, but also have reliable load-bearing capacity, thermal shock resistance and slag resistance.

[0094] Optionally, the inner wall of the furnace chamber 220 is covered with an asbestos layer. After the furnace chamber 220 is closed, the walls of the furnace chamber 220 that are exposed to the open flame environment and are used to surround the oilstone substrate are all covered with an asbestos layer. Asbestos materials have high fire resistance and also have the functions of heat preservation, fire prevention, heat insulation, corrosion resistance, sound insulation, insulation, etc.

[0095] Optionally, the sintering furnace 200 also includes a conveying mechanism, which is used to drive the material rack 210 in and out of the furnace chamber 220; the conveying mechanism includes: a ground rail 231, which is extended toward the furnace chamber 220; a rail trolley 232, which is slidably set on the ground rail 231, and is used to carry the material rack 210; an inlet and outlet are provided on one side of the furnace chamber 220, and a movable channel is provided at the bottom, and the movable channel connects the inlet and outlet, and the rail trolley 232 can deliver the material rack 210 into the furnace chamber 220 through the inlet and outlet and the movable channel; the sintering furnace 200 also includes a base 240, which is made of refractory bricks, and the base 240 is arranged on the rail trolley 232, and the material rack 210 is arranged on the base 240; after the rail trolley 232 delivers the material rack 210 into the furnace chamber 220, the base 240 can close the movable channel and constitute the furnace bottom of the furnace chamber 220.

[0096] For details, please refer to Figure 8In the illustrated embodiment, an inlet and an outlet are provided on the side of the furnace chamber 220 facing the paper surface, and a movable channel connecting the inlet and the outlet and extending in a direction perpendicular to the paper surface is provided at the bottom of the furnace chamber 220; a ground rail 231 extends toward the furnace chamber 220 in a direction perpendicular to the paper surface; and the rail trolley 232 can deliver the material rack 210 into the furnace chamber 220 along the ground rail 231.

[0097] Combined with reference Fig. 9 The sintering furnace 200 further includes a steel frame, on which a furnace chamber 220 is disposed; the furnace chamber 220 is suspended above the ground through the steel frame. A base 240 is disposed on the rail trolley 232; after the rail trolley 232 moves to the bottom of the furnace chamber 220, part of the base 240 is in the furnace chamber 220 and another part of the base 240 is under the furnace chamber 220; at this time, the base 240 closes the movable channel and constitutes the furnace bottom of the furnace chamber 220.

[0098] By closing the movable channel through the base 240, the material rack 210 can keep the oilstone substrate in the furnace chamber 220 so that the oilstone substrate can be sintered in a high temperature environment of open flame; and the conveying mechanism is outside the furnace chamber 220 and will not be directly affected by the high temperature of the open flame, which is beneficial to the service life and safety of the conveying mechanism.

[0099] Optionally, the furnace chamber 220 is also provided with a door, which is used to close the entrance and exit. The door can be installed by rotation, translation, etc.

[0100] Optionally, the conveying mechanism further includes a transport drive, which is used to drive the rail trolley 232 to move along the ground rail 231. The transport drive can be a drive structure such as an electric cylinder or a linear module, or a motor, which is used to drive the roller of the rail trolley 232 to rotate.

[0101] Optionally, the conveying mechanism further includes a handle, which is disposed on a side of the rail trolley 232 facing away from the furnace chamber 220 ; a worker can push or pull the furnace chamber 220 through the handle.

[0102] Optionally, limiting protrusions 241 are provided on both sides of the base 240, and limiting slide grooves 242 are provided on both sides of the movable channel; when the rail trolley 232 moves along the ground rail 231 toward the furnace chamber 220, the limiting protrusion 241 can be inserted into the limiting slide groove 242 and penetrate deeper along the limiting slide groove 242.

[0103] For details, please refer to Figure 8 In the illustrated embodiment, two limiting slide grooves 242 are provided under the furnace chamber 220. The limiting slide grooves 242 are roughly C-shaped, and the two limiting slide grooves 242 are arranged opposite to each other along the left and right directions; any limiting slide groove 242 extends in a direction perpendicular to the paper surface; along the left and right directions, the two limiting slide grooves 242 are arranged on both sides of the movable channel.

[0104] Continue to refer to Figure 8 In the left-right direction, a limiting protrusion 241 is respectively provided on both sides of the base 240; any limiting protrusion 241 is extended in a direction perpendicular to the paper surface. The center height of the limiting protrusion 241 is close to the center height of the limiting slide 242. When the rail trolley 232 moves toward the furnace chamber 220, the limiting protrusion 241 can be inserted into the limiting slide 242.

[0105] When the rail trolley 232 moves along the ground rail 231 to the bottom of the furnace chamber 220, so that the rack 210 and the oilstone substrate are in the sintering position, the limiting protrusion 241 is inserted into the limiting slide 242. The insertion and cooperation of the limiting protrusion 241 and the limiting slide 242 can not only play a limiting role and improve the reliability of the transportation of the rail trolley 232 and the rack 210, but also better close the activity channel to prevent the sintering environment from leaking out.

[0106] Optionally, the sintering furnace 200 further includes an ignition assembly, which is disposed in the furnace chamber 220 and connected to the natural gas supply pipeline. When working, the conveying mechanism can deliver the oilstone substrate to be sintered into the furnace chamber 220, the furnace chamber 220 is closed, and the ignition assembly works to sinter the oilstone substrate by an open flame. By using natural gas to achieve open flame sintering, the safety performance is high and it is not easy to have dangerous situations such as explosions. Since natural gas is a clean energy, it does not need to recycle and treat the waste gas to meet the emission standards, which is convenient and easy to use.

[0107] Specifically, the ignition assembly includes a gas nozzle, a solenoid valve and a spark plug. The gas nozzle is arranged in the furnace chamber 220 and connected to the natural gas supply pipeline. The solenoid valve is arranged on the natural gas supply pipeline. The working end of the spark plug is close to the spray hole of the gas nozzle. The conveying mechanism delivers the oilstone substrate into the furnace chamber 220. After the furnace chamber 220 is closed, the solenoid valve is opened, and the natural gas flows into the gas nozzle through the pipeline. At the same time, the spark plug is started, and the spark plug generates a high-voltage electric spark, which can ignite the natural gas sprayed through the spray hole of the gas nozzle, thereby generating an open flame in the furnace chamber 220.

[0108] Optionally, the ignition assembly includes two rows of igniters, and each row includes a plurality of igniters spaced apart along the transport direction; after the conveying mechanism delivers the oilstone into the furnace chamber 220, the oilstone substrate is located between the two rows of igniters. By providing two rows of igniters and allowing the oilstone substrate to be sintered between the two rows of igniters, it is possible to well ensure that the oilstone substrate is surrounded by a sintering environment, and to ensure that the environment in the furnace chamber 220 is balanced, thereby ensuring the sintering effect of the oilstone substrate.

[0109] Optionally, the sintering furnace 200 further includes a temperature measuring rod, which is disposed in the furnace chamber 220 and is used to monitor the sintering environment.

[0110] Optionally, the sintering furnace 200 also includes a ventilation and exhaust component 250, which is connected to the furnace chamber 220, and can both exhaust the smoke generated by sintering and allow air to enter the furnace chamber 220; the ventilation and exhaust component 250 includes: a horizontal pipe 251, one end of the horizontal pipe 251 is connected to the furnace chamber 220, and the other end is provided with a first air port 251a; a vertical pipe 252, the bottom end of the vertical pipe 252 is connected to the horizontal pipe 251, and the top end extends vertically; a second air port 252a is also provided on the horizontal pipe 251 located between the vertical pipe 252 and the furnace chamber 220.

[0111] For details, please refer to Fig. 9 In the illustrated embodiment, an inlet and outlet and a door are provided on the left side of the furnace chamber 220, and a gas passage is provided on the wall on the right side; the left end of the horizontal pipe 251 is provided on the right side of the furnace chamber 220 and connected to the gas passage; the right end of the horizontal pipe 251 is provided with a first gas port 251a, and the first gas port 251a is connected to the atmospheric environment, and air can enter the furnace chamber 220 through the first gas port 251a, the horizontal pipe 251 and the gas passage, thereby promoting open flame operation. A vertical pipe 252 extending up and down is provided on the horizontal pipe 251; since the hot gas molecules are active and will float upward, the high-temperature exhaust gas generated by sintering will enter the gas passage along the horizontal pipe 251 into the vertical pipe 252, and then be discharged outward. A second gas port 252a is also provided on the horizontal pipe 251 between the furnace chamber 220 and the vertical pipe 252, and the second gas port 252a has the function of replenishing gas.

[0112] Optionally, the ventilation and exhaust assembly 250 further includes a blower, which is detachably arranged on the first air port 251a or the second air port 252a. By installing a blower, air circulation can be promoted, thereby promoting open flame operations.

[0113] For example, when the temperature measuring rod detects that the sintering environment in the furnace chamber 220 does not meet the operating requirements, the sintering can be promoted by adding a blower.

[0114] Optionally, the ventilation exhaust assembly 250 further includes a cover, which is detachably disposed on the first air port 251a or the second air port 252a. When the cover is installed, the first air port 251a or the second air port 252a can be blocked; when the cover is removed, the first air port 251a or the second air port 252a can be normally supplied with air.

[0115] For example, when air replenishment is not needed, the second air port 252a is blocked by the blocking cover.

[0116] For another example, after sintering is completed and the flame is turned off, the first gas port 251a and the second gas port 252a are blocked by the blocking cover, which is beneficial to heat preservation of the furnace chamber 220 and optimizes the sintering effect of the oilstone substrate.

[0117] Optionally, the cutter 320 is a circular blade; the dry cutting machine 300 further includes a rotary drive member 330, which is used to drive the cutter 320 to rotate so that the cutter 320 can cut the dense material block.

[0118] During the dry cutting process, the cutter 320 acts on the dense material block in a rotating posture, which can not only enhance the cutting force and accelerate the cutting through the high-speed rotation of the blade end, but also avoid continuous operation of the blade end at a single position, which is beneficial to improving the service life and stability of the cutter 320.

[0119] Furthermore, in order to facilitate the rotary cutting of the circular blade, a clearance hole is provided on the machine table 310, and the cutter 320 is suspended in the clearance hole. At this time, the dense material block placed at the cutting station is pushed along the table surface of the machine table 310 toward the rotating cutter 320, and the cutter 320 can gradually cut the dense material block.

[0120] Optionally, the dry cutting machine 300 also includes a cutting drive assembly 340, which is used to drive the cutter 320 and the dense material block on the cutting station to move closer to or farther away from each other; when the cutter 320 approaches the dense material block on the cutting station, the cutter 320 can act on the dense material block to achieve cutting; when the cutter 320 moves away from the dense material block on the cutting station, the dense material block can be displaced, or a new dense material block to be cut can enter the cutting station.

[0121] Optionally, the dry cutting machine 300 further comprises a clamp, which is arranged at the cutting station and is used to clamp the dense material block to be cut. The dense material block is fixed by the clamp so that the cutter 320 can accurately act on the dense material block.

[0122] In a specific embodiment, a clamp and a cutting drive assembly 340 are provided at the cutting station. A mounting plate 343 is provided at the movable end of the cutting drive assembly 340; the clamp comprises: a fixed clamp block 351, fixedly arranged on the mounting plate 343; a movable clamp block 352, slidably arranged on the mounting plate 343; an elastic member 353, one end of which is connected to the movable clamp block 352 and the other end of which is connected to the mounting plate 343; when the fixed clamp block 351 cooperates with the movable clamp block 352 to clamp the dense material block, the elastic member 353 is in a compressed state.

[0123] For details, please refer to Fig.10In the illustrated embodiment, the cutter 320 is arranged above the cutting station; the fixed clamp block 351 and the movable clamp block 352 are arranged opposite to each other in the left-right direction; the fixed clamp block 351 is fixedly arranged on the mounting plate 343 and cannot be actively moved left-right; the movable clamp block 352 is movably arranged on the mounting plate 343 through an elastic member 353 (which can be made of elastic material, or can be an elastic structure such as a spring or a spring sheet) and can be moved left-right. The dense material block to be cut is placed between the fixed clamp block 351 and the movable clamp block 352, and the elastic member 353 is in a compressed state, and its elastic force acts in the opposite direction on the movable clamp block 352, so that the movable clamp block 352 presses the dense material block against the fixed clamp block 351. Since the fixed clamp block 351 cannot be actively displaced left-right, the fixed clamp block 351 can be used as the basic position for cutting the dense material block, ensuring that the distance between the cutter 320 and the fixed clamp block 351 in the left-right direction is the required cutting length, thereby ensuring the accuracy and uniformity of cutting.

[0124] Continue to refer to Fig.10 When the dense material block to be cut is between the fixed clamp block 351 and the movable clamp block 352, the left end of the dense material block is limited by the fixed clamp block 351, the right end is limited by the movable clamp block 352, the lower side is limited by the mounting plate 343, and the bottom is limited by the table 310; the position and state of the dense material block in the cutting station must be unified, determined and stable. The upper side of the dense material block is facing the cutter 320, and the dense material block moves toward the cutter 320 through the cutting drive assembly 340, and the cutter 320 can act on the dense material block stably and accurately.

[0125] Furthermore, the cutting drive assembly 340 includes a first horizontal direction drive member 341 and a second horizontal direction drive member 342. The first horizontal direction drive member 341 is used to drive the mounting plate 343 to move along the first horizontal direction so that the mounting plate 343 pushes the dense material block toward the cutter 320. The second horizontal direction drive member 342 is used to drive the mounting plate 343 to move along the second horizontal direction so that the cutter 320 faces different parts of the dense material block.

[0126] For details, please refer to Fig.10 In the illustrated embodiment, the first horizontal direction is the up-down direction, and the second horizontal direction is the left-right direction. At the same time, the first horizontal direction can be regarded as the width direction of the dense material block, and the second horizontal direction can be regarded as the length direction of the dense material block. The mounting plate 343 is arranged at the movable end of the first horizontal direction driving member 341, and the first horizontal direction driving member 341 is arranged at the movable end of the second horizontal direction driving member 342.
