After the finished product is taken away, the output end of the No. 1 electric cylinder 12 slides down, driving the shovel block 14 to scrape the inner wall of the pressing cavity 11 again to reduce the residual metal powder on the inner wall of the pressing cavity 11 and reduce the looseness of the edge of the finished product after demolding, thereby improving the quality of the pressed product.

[0029] A pressing assembly is provided at the end of the device base 1; the pressing assembly includes a support frame 2, a hydraulic cylinder 21 and a pressing mold 22; the support frame 2 is fixedly connected to the outer wall of the device base 1; the hydraulic cylinder 21 is fixedly connected to the bottom of the support frame 2, and the hydraulic cylinder 21 is located directly above the pressing cavity 11; the pressing mold 22 is fixedly connected to the output end of the hydraulic cylinder 21, and the pressing mold 22 is arranged corresponding to the pressing cavity 11; when the metal powder in the pressing cavity 11 is pressed, the metal powder is pressed and formed by the pressing assembly, the support frame 2 supports the hydraulic cylinder 21 to be located directly above the pressing cavity 11, the output end of the hydraulic cylinder 21 drives the pressing mold 22 to press down, and the pressing mold 22 is pressed into the interior of the pressing cavity 11, and the metal powder in the pressing cavity 11 is pressed and formed, thereby playing a role in pressing and forming the metal powder.

[0030] The shovel block 14 includes two annular scrapers with blades facing opposite directions; an annular block is arranged at the bottom end of the shovel block 14; a plurality of brushes 3 are fixedly connected to the outer wall of the annular block, and the plurality of brushes 3 are arranged in an annular array; when the metal powder finished product is demolded, the No. 1 electric cylinder 12 drives the annular scraper of the shovel block 14 to slide up and scrape the inner wall of the pressing cavity 11, and the position of the inner wall of the pressing cavity 11 after being scraped is then cleaned by the plurality of brushes 3 on the outer wall of the annular block, thereby improving the cleaning effect of the inner wall of the pressing cavity 11 and reducing the quality impact of the residual metal powder on the finished product. At the same time, after the finished product is taken away, the output end of the No. 1 electric cylinder 12 slides down, driving another annular scraper of the shovel block 14 to scrape the inner wall of the pressing cavity 11 again, thereby reducing the adhesion of metal powder on the inner wall of the pressing cavity 11.

[0031] like Figures 1 to 4 As shown, the outer wall of the device base 1 is fixedly connected to a fixing frame 4; the outer wall of the fixing frame 4 is fixedly connected to a No. 2 electric cylinder 41; the output end of the No. 2 electric cylinder 41 is fixedly connected to a connecting block 42; the outer wall of the connecting block 42 on the side away from the No. 2 electric cylinder 41 is fixedly connected to a pushing plate 43; when the metal powder is pressed and formed, the finished product is pushed out of the pressing cavity 11 by relying on the pushing block 13, and then the output end of the No. 2 electric cylinder 41 on the fixing frame 4 extends forward, driving the pushing plate 43 at the front end of the connecting block 42 to slide on the end of the device base 1, and the pushing plate 43 shovels the finished product away, making it easier to continue pressing the metal powder and playing a role in automatically unloading the pressed finished product.

[0032] like Figures 1 to 5As shown, a feeding channel 5 is provided in the middle of the connecting block 42; a storage box 51 is fixedly connected to the end of the fixing frame 4; a storage cavity 52 is provided inside the storage box 51, and a discharge port of the storage cavity 52 is arranged corresponding to the feeding channel 5; a blocking plate 53 is fixedly connected to the outer wall of the connecting block 42 near the upper side of the No. 2 electric cylinder 41; when the metal powder is pressed, a large amount of metal powder is stored in the storage cavity 52 inside the storage box 51, and the metal powder falls from the discharge port of the storage cavity 52 to the bottom. The metal powder is temporarily stored in the material channel 5. When the No. 2 electric cylinder 41 drives the pushing plate 43 to push and press the finished product, the sealing plate 53 blocks the discharge port of the storage chamber 52, and the material discharge channel 5 coincides with the pressing chamber 11. The metal powder temporarily stored in the material discharge channel 5 falls into the pressing chamber 11, which plays a role in feeding the metal powder. At the same time, when the No. 2 electric cylinder 41 drives the connecting block 42 to slide back, the inner wall of the connecting block 42 can scrape and smooth the metal powder in the pressing chamber 11, thereby improving the effect of pressing the metal powder.

[0033] like Figures 1 to 4 As shown, a heater 6 is fixedly connected to the end of the device base 1 away from the fixing frame 4; two transmission rods 61 are rotatably connected to the inner wall of the device base 1 near the heater 6; a conveyor belt 62 is rotatably connected to the outer wall of the transmission rod 61, and the conveyor belt 62 is installed on the two transmission rods 61; a transmission assembly is provided at the end of one of the transmission rods 61, and the transmission assembly is used to drive the transmission rod 61 to rotate; a heat-conducting cylinder 63 is fixedly connected to the inner wall of the device base 1 near the pressing chamber 11, and the heat-conducting cylinder 63 is connected to the heater 6 through a heat-conducting wire; when the metal powder is pressed and demolded, the periphery of the pressed product is easy to loosen, and the heater 6 is fixed on the unloading side of the pressed product for heating. The transmission assembly operates as the connecting block 42 slides, driving the conveyor belts 62 on the two transmission rods 61 to rotate. A finished product is pushed and shoveled by the push plate 43 and falls onto the conveyor belt 62. As the next finished product is pressed out and pushed and shoveled, the transmission assembly is triggered again to drive the conveyor belt 62 to rotate. The conveyor belt 62 delivers the previous finished product to the bottom end of the heater 6. The heater 6 heats and burns the previous finished product, and continues to heat and burn multiple finished products in sequence, thereby improving the quality of the finished products. At the same time, part of the heat generated by the heater 6 is transferred to the heat-conducting tube 63 by relying on the heat-conducting wire. The heat-conducting tube 63 is installed in the pressing chamber 11. The conducted heat can heat the metal powder in the pressing chamber 11, thereby improving the pressing effect of the metal powder.

[0034] The transmission assembly includes a ratchet mechanism 7 and a No. 1 rack plate 71; the two ratchet mechanisms 7 are fixedly connected to the two ends of a transmission rod 61; the two No. 1 rack plates 71 are respectively fixedly connected to the two sides of the connecting block 42, and the teeth of the No. 1 rack plate 71 can mesh with the ratchet mechanism 7; when the finished product of the pressed demolding is heated and fired, the output end of the No. 2 electric cylinder 41 drives the connecting block 42 to slide, and the connecting block 42 synchronously drives the No. 1 rack plates 71 on both sides to slide, and the teeth at the bottom end of the No. 1 rack plate 71 mesh with the ratchet mechanism 7 to rotate, driving a transmission rod 61 to rotate, and the conveyor belt 62 rotates accordingly to drive the finished product at its end to be transported, heated and fired, and the ratchet mechanism 7 can adopt a transmission structure that a traditional bicycle cannot be ridden backwards. When the No. 1 rack plate 71 slides forward, it can only drive the conveyor belt 62 to rotate toward the lower material, and the No. 1 rack plate 71 will not drive the conveyor belt 62 to rotate in the opposite direction when resetting, thereby playing a role in transmitting and conveying the pressed finished product.

[0035] like Figures 1 to 3 , Figure 5 As shown, the inner wall of the storage box 51 is slidably connected with a push plate 8; the inner wall of the storage box 51 is slidably connected with a sliding plate 81, and the sliding plate 81 is fixedly connected to one end of the push plate 8; an air guide tube 82 is fixedly connected inside the storage box 51 and near the sliding plate 81; an extrusion assembly is provided at one end of the air guide tube 82 away from the storage box 51, and the extrusion assembly is used to extrude gas to push the push plate 8 to slide; when metal powder is added to the storage box 51, since a large amount of metal powder temporarily stored in the storage cavity 52 is easy to accumulate in one place and is difficult to fall, the extrusion assembly is triggered by the downward movement of the output end of the hydraulic cylinder 21, and the extrusion assembly squeezes the gas from one end of the air guide tube 82 to the other end, and the gas reaches the storage box 51, and the gas pushes the push plate 8 connected to the sliding plate 81 to slide, and the push plate 8 pushes the metal powder near the discharge port in the storage cavity 52, and the side of the push plate 8 can open a guide channel, which can reduce the situation of reset blockage of the push plate 8, push the metal powder, and improve the falling effect of the metal powder in the storage cavity 52.

[0036] The extrusion assembly includes an extrusion plate 9 and an air cylinder 91; the extrusion plate 9 is fixedly connected to the outer wall of the output end of the hydraulic cylinder 21; the two air cylinders 91 are fixedly connected to the end of the device base 1, the two air cylinders 91 are located below the extrusion plate 9, and the two air cylinders 91 are connected to the air guide pipe 82; when the pushing plate 8 pushes the metal powder in the storage chamber 52 to fall, the output end of the hydraulic cylinder 21 drives the extrusion plate 9 to slide down, the extrusion plate 9 squeezes the two air cylinders 91, and squeezes the gas inside the two air cylinders 91 into the air guide pipe 82. After the gas enters the storage box 51, it pushes the pushing plate 8 connected to the sliding plate 81 to slide, thereby achieving the function of pushing the metal powder to fall.

[0037] A connecting frame 92 is fixedly connected to the inner wall of the storage box 51, and the connecting frame 92 is located at the discharge port of the storage cavity 52; the end of the connecting frame 92 is rotatably connected to a stirring blade 93; a gear 94 is fixedly connected to the middle outer wall of the stirring blade 93; a No. 2 rack plate 95 is fixedly connected to the outer wall of the pushing plate 8 close to the stirring blade 93, and the teeth of the No. 2 rack plate 95 can mesh with the gear 94; when the metal powder in the storage cavity 52 is dropped, the pushing plate 8 is used to drive the No. 2 rack plate 95 to slide, and the No. 2 rack plate 95 meshes with the gear 94 to drive the stirring blade 93 to rotate on the connecting frame 92. The rotation of the stirring blade 93 can accelerate the dropping of the metal powder at the discharge port, thereby improving the dropping effect of the metal powder. At the same time, if the metal powder is agglomerated, the rotation of the stirring blade 93 can break up the agglomerates, thereby reducing the accumulation of metal powder agglomerates at the discharge port.

[0038] Working process: When pressing the metal powder, first put the metal powder into the pressing cavity 11 at the end of the device base 1, and place it at the end of the push block 13, smooth the pressing cavity 11 at the end of the device base 1, and then press the metal powder at the pressing cavity 11 into shape, place the pressed product at the end of the push block 13, and start demoulding the pressed product. The output end of the No. 1 electric cylinder 12 drives the push block 13 to slide up, and the shovel block 14 slides up synchronously with the push block 13, and the shovel block 14 scrapes the inner wall of the pressing cavity 11 to reduce the adhesion of fine metal powder on the inner wall of the pressing cavity 11, until the pressed product is pushed out of the pressing cavity 11, and the finished product is taken out. After the movement, the output end of the No. 1 electric cylinder 12 slides down, driving the shovel block 14 to scrape the inner wall of the pressing cavity 11 again, reducing the residual metal powder on the inner wall of the pressing cavity 11, reducing the loose edge of the finished product after demolding, thereby improving the quality of the pressed product; when the metal powder in the pressing cavity 11 is pressed, the metal powder is pressed and formed by the pressing assembly, and the support frame 2 supports the hydraulic cylinder 21 to be located directly above the pressing cavity 11. The output end of the hydraulic cylinder 21 drives the pressing mold 22 to press down, and the pressing mold 22 is pressed into the interior of the pressing cavity 11 to press the metal powder in the pressing cavity 11 into shape, thereby playing the role of pressing and forming the metal powder;

[0039] When demoulding the finished metal powder product, the No. 1 electric cylinder 12 drives the annular scraper of the shovel block 14 to slide upward and scrape the inner wall of the pressing cavity 11. The scraped position of the inner wall of the pressing cavity 11 is then cleaned by multiple brushes 3 on the outer wall of the annular block, thereby improving the cleaning effect of the inner wall of the pressing cavity 11 and reducing the quality impact of residual metal powder on the finished product. At the same time, after the finished product is taken away, the output end of the No. 1 electric cylinder 12 slides down, driving another annular scraper of the shovel block 14 to scrape the inner wall of the pressing cavity 11 again, thereby reducing the adhesion of metal powder on the inner wall of the pressing cavity 11.

[0040] After the metal powder is pressed and formed, the finished product is pushed out of the pressing chamber 11 by the push block 13, and then the output end of the No. 2 electric cylinder 41 on the fixed frame 4 extends forward, driving the push plate 43 at the front end of the connecting block 42 to slide at the end of the device base 1, and the push plate 43 shovels the finished product away to facilitate the continued pressing of the metal powder, which plays a role in automatically unloading the pressed finished product; when the metal powder is pressed, a large amount of metal powder is stored in the storage chamber 52 inside the storage box 51, and the metal powder is discharged from the storage chamber 52. The metal powder temporarily falls into the material discharge channel 5 for temporary storage. When the No. 2 electric cylinder 41 drives the push plate 43 to push and shovel the finished product, the blocking plate 53 blocks the discharge port of the storage chamber 52, and the material discharge channel 5 coincides with the pressing chamber 11. The metal powder temporarily stored inside the material discharge channel 5 falls into the pressing chamber 11, which plays a role in feeding the metal powder. At the same time, when the No. 2 electric cylinder 41 drives the connecting block 42 to slide back, the inner wall of the connecting block 42 can scrape and smooth the metal powder at the pressing chamber 11, thereby improving the effect of pressing the metal powder.

[0041] After the metal powder is pressed and molded and demolded, the periphery of the pressed product is easy to loosen. The heater 6 is fixed on the unloading side of the pressed product to heat it. The transmission component slides with the connecting block 42 and runs, driving the conveyor belt 62 on the two transmission rods 61 to rotate. A finished product is pushed and shoveled by the pushing plate 43 and falls on the conveyor belt 62. As the next finished product is pressed and shoveled, the transmission component is triggered again to drive the conveyor belt 62 to rotate. The conveyor belt 62 sends the previous finished product to the bottom end of the heater 6. The heater 6 heats and burns the previous finished product, and continues to heat and burn multiple finished products in sequence, thereby improving the quality of the finished products. At the same time, the heat generated by the heater 6 is transferred to the heat-conducting tube 63 by the heat-conducting wire. The heat-conducting tube 63 is installed in the pressing chamber 11. The conducted heat can heat the metal powder in the pressing chamber 11, thereby improving the pressing effect of the metal powder; when the pressed and demolded finished product is heated and fired, the output end of the No. 2 electric cylinder 41 drives the connecting block 42 to slide, and the connecting block 42 synchronously drives the No. 1 rack plate 71 on both sides to slide, and the teeth at the bottom end of the No. 1 rack plate 71 mesh with the ratchet mechanism 7 to rotate, driving a transmission rod 61 to rotate, and the conveyor belt 62 rotates accordingly to drive the finished product at its end to be transported, heated and fired, and the ratchet mechanism 7 can adopt a transmission structure that cannot be ridden backwards on a traditional bicycle. When the No. 1 rack plate 71 slides forward, it can only drive the conveyor belt 62 to rotate toward the lower material, and the No. 1 rack plate 71 will not drive the conveyor belt 62 to rotate in the opposite direction when it is reset, thereby playing a role in transmitting and conveying the pressed finished product;

[0042] After the metal powder is added to the storage box 51, since a large amount of metal powder temporarily stored in the storage chamber 52 is easy to accumulate in one place and is difficult to fall, the output end of the hydraulic cylinder 21 is used to slide down to trigger the extrusion component, and the extrusion component squeezes the gas from one end of the air guide pipe 82 to the other end. The gas reaches the storage box 51, and the gas pushes the push plate 8 connected to the sliding plate 81 to slide. The push plate 8 pushes the metal powder near the discharge port in the storage chamber 52. The side of the push plate 8 can be provided with a guide channel, and the guide channel can reduce the reset blockage of the push plate 8, push the metal powder, and improve the blanking effect of the metal powder in the storage chamber 52; when the push plate 8 pushes the metal powder in the storage chamber 52 to fall, the output end of the hydraulic cylinder 21 drives the extrusion plate 9 to slide down, and the extrusion plate 9 squeezes the two air cylinders 91, squeezes the gas inside the two air cylinders 91 into the air guide pipe 82, and the gas enters the storage box 51 and pushes the push plate 8 connected to the sliding plate 81 to slide, thereby achieving the effect of pushing the metal powder to fall;

[0043] When the metal powder in the storage chamber 52 is dropped, the push plate 8 is used to drive the second rack plate 95 to slide, and the second rack plate 95 is meshed with the gear 94 to drive the stirring blade 93 to rotate on the connecting frame 92. The rotation of the stirring blade 93 can accelerate the dropping of the metal powder at the discharge port, thereby improving the dropping effect of the metal powder. At the same time, if the metal powder is agglomerated, the rotation of the stirring blade 93 can break up the agglomerates, thereby reducing the accumulation of metal powder agglomerates at the discharge port.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
