Description

Technical Field

[0001] This invention relates to the technical field of continuous forging equipment for metal powder, specifically a continuous forging equipment for metal powder processing. Background Technology

[0002] Metal powder processing forging is a process that uses metal powder as raw material. It first undergoes pretreatment such as pressing and sintering to form a preform, and then applies external force at room temperature or high temperature using forging equipment (such as hydraulic presses and forging hammers) to cause plastic deformation of the preform. This process eliminates the porosity between powder particles, increases the density of the material, refines the grains, and optimizes the microstructure, ultimately obtaining metal parts with high density, excellent mechanical properties (strength, hardness, toughness), and good dimensional accuracy. It is widely used in aerospace, automobile manufacturing and other fields, and can produce complex, high-performance components that are difficult to achieve with traditional processes.

[0003] Metal powder processed parts are made from metal powder as raw material. They are first pre-formed into blanks through pressing, sintering and other pre-treatment processes. During the pressing process, a forging device is needed to initially shape the metal powder in the mold for subsequent sintering and polishing. The existing forming method is the traditional metal powder processing forging method for small metal parts. In this method, the powder is manually pushed and pulled into the mold by the operator, placed in the stamping position for forging, and then manually demolded. Only one part can be produced at a time, which results in low efficiency and increases the labor intensity of the operator. It is impossible to improve efficiency through continuous forging, which brings certain inconveniences. Based on this, a continuous forging equipment for metal powder processing is proposed.

[0010] Preferably, the powder metering pump is fixedly installed at the bottom of the top plate by a horizontal bracket, and the specifications and dimensions of the flexible guide head are adapted to the specifications and dimensions of the mold groove.

[0011] Preferably, three suction heads are fixedly installed on one side of the top of the workbench. The bottom ends of the three suction heads are connected to suction pipes, and the bottom ends of the suction pipes are connected to filter cartridges.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During operation, the powder is pumped by the powder metering pump and falls into the inner side of the mold groove through the output pipe and flexible guide head. Then, the conveying power mechanism drives the plate conveyor belt to rotate. It stops to fill after conveying one grid. At this time, the deceleration servo motor drives the actuating plate to rotate slowly and gradually, and pushes a part of the top of the mold groove to rotate and flatten it. The first scraper and the second scraper gradually push and completely scrape the powder on the top of the mold groove and the inner mold. The lower mold moves to the bottom of the upper mold. The output of the electro-hydraulic cylinder drives the upper mold to embed into the mold groove, and the metal powder is continuously forged multiple times to promote the metal powder to form. When it is taken out, the electro-hydraulic rod extends to press the pressing column and pushes a part of the formed metal part out to the outside of the mold groove. The operator manually takes out the formed metal part. The overall operation efficiency is high, the labor intensity of the operator is reduced, and the metal powder processing can be continuously forged, which increases the efficiency of continuous production forming.

[0016] 2. When removing the forged part, the lower mold moves to the output end of the electro-hydraulic rod one. The electro-hydraulic rod one extends to press the pressing column, which drives the sealing piston two to move. Through the hydraulic oil in the connecting groove and the mold groove, the sealing piston one and the mold groove matching column are pushed upward, pushing a portion of the formed metal part out of the mold groove. The operator manually removes the formed metal part and presses the mold groove matching column and sealing piston one downward to reset them. The operation is simple, optimizes the operation process and steps of the operator, reduces the operator's involvement in the process, increases efficiency, and reduces the labor intensity of the operator.

[0017] 3. This solution uses a plate conveyor belt to align the flexible silicone cover with the suction head. At this point, the suction pump starts, generating airflow suction on the filter cartridge and the extraction pipe. The metal powder and airflow inside the outer ring and inner mold are extracted through the suction pipe and guided by the suction pipe and the suction head into the filtration range of the dust filter bag. The metal powder accumulates under the filtration of the dust filter bag, and the airflow is discharged by the suction pump. The accumulated metal powder in the dust filter bag is guided through the sealed insertion tube and then through the guide pipe to the sealed container for collection. This facilitates the collection of excess scraped and flattened metal powder, which can be added back into the powder storage container later. This reduces the difficulty of manual collection, increases the usage effect, and facilitates recycling. Attached Figure Description

[0029] Please see Figures 1-9This invention provides a technical solution: a continuous forging press for metal powder processing, comprising a worktable 1 and a lower die 6.

A conveying pipe is connected to the output end of the screw conveyor pump 15. 16. The end of the conveying pipe 16 away from the screw conveyor pump 15 is connected to the powder metering pump 17. The output end of the powder metering pump 17 is connected to the output pipe 18. The bottom of the output pipe 18 is connected to the flexible guide head 26. Three infrared sensors 23 are fixedly installed on one side of the top of the workbench 1. A bracket 9 is fixedly installed on the top of one end of the workbench 1. An electro-hydraulic rod 25 is fixedly installed on the bottom surface of the top of the bracket 9. A support plate 29 is fixedly installed on the top of the other end of the workbench 1. A reduction servo motor 27 is fixedly sleeved inside the top of the support plate 29. Several toggle plates 28 are fixedly installed on the output end of the reduction servo motor 27. A first scraper 30 is fixedly installed on the bottom of the support plate 29 away from the reduction servo motor 27. A second scraper 31 is fixedly installed on the bottom of the support plate 29 away from the reduction servo motor 27.

[0030] The lower mold 6 includes a mounting plate 605. An outer ring 601 is fixedly mounted on the top of the mounting plate 605. An inner mold 602 is sleeved on the inner side of the outer ring 601. A mold groove 603 is opened on the inner side of the inner mold 602. A mold groove fitting post 606 is movably sleeved on the inner side of the mold groove 603. A sealing piston 607 is movably mounted on the bottom of the mold groove fitting post 606. A hollow support frame 608 is provided at the bottom of the sealing piston 607. A connecting groove 610 is connected to one side of the bottom end of the mold groove 603. A sealing piston 609 is movably sleeved on the inner side of the connecting groove 610. A pressing post 604 is fixedly mounted on one side of the sealing piston 609. An air suction pipe 7 is connected to one side of the outer ring 601. A silicone flexible cover 8 is fixedly mounted on the other end of the air suction pipe 7.

[0031] The working principle of the above technical solution is as follows: During use, the user adds metal powder to the inside of the powder placement cylinder 14. During operation, the screw conveyor pump 15 transports the powder falling from the powder placement cylinder 14 to the input end of the powder metering pump 17 through the conveying pipe 16. Then, through the metering pump of the powder metering pump 17, the powder falls into the inner side of the mold groove 603 through the output pipe 18 and the flexible guide head 26. Then, the conveying power mechanism 5 drives the plate conveyor belt 4 to rotate, and stops filling after conveying one section. At this time, the reduction servo motor 27 drives the actuating plate 28 to rotate slowly and gradually, pushing and flattening a portion of the top of the mold groove 603, so that the top of the mold groove 603 is filled with metal powder. Then, with the gradual transmission, the first scraper 30 gradually pushes the powder on the top of the mold groove 603 and the inner mold 602, and the excess part falls to the opposite side of the outer ring 601 and the inner mold 602. Then, the second scraper 31 pushes the powder on the top of the inner mold 602 and the mold groove 603. The metal powder is completely scraped off. The lower mold 6 moves to the bottom of the upper mold 22. The output of the electro-hydraulic cylinder 13 drives the slide plate 12 and the upper mold 22 to move down. The upper mold 22 is embedded in the mold groove 603, and the metal powder is continuously forged multiple times to form the metal powder. Then, when the lower mold 6 moves to the output end of the electro-hydraulic rod 25, the electro-hydraulic rod 25 extends to press the pressing column 604. The pressing column 604 drives the sealing piston 609 to move. Through the hydraulic oil in the connecting groove 610 and the mold groove 603, the sealing piston 607 and the mold groove engaging column 606 are pushed up, pushing a part of the formed metal part out of the mold groove 603. Then, the operator manually removes the formed metal part and presses the mold groove engaging column 606 and the sealing piston 607 down to reset them. The overall operation efficiency is high, the labor intensity of the operator is reduced, and the metal powder processing can be continuously forged, increasing the efficiency of continuous production forming.

[0032] In another implementation scheme, such as Figures 1-7 As shown, the plate conveyor belt 4 is movably sleeved on the outside of the workbench 1, and the bottom of the plate conveyor belt 4 is in sliding contact with the top of the workbench 1. The conveying power mechanism 5 is supported by a bracket and installed on the outside of both ends of the workbench 1. The mounting plate 605 is fixedly installed on the outside of the plate conveyor belt 4 by bolts. The lower mold 6 is evenly distributed in a circular linear pattern on the outside of the plate conveyor belt 4.

[0033] The bottom of the plate conveyor belt 4 slides in contact with the top of the workbench 1. This smooth sliding contact supports the bottom of the plate conveyor belt 4. On the opposite side of the bottom of the plate conveyor belt 4 and the top of the workbench 1, a rough surface is provided at a location corresponding to the rear of the flexible guide head 26. When the flexible guide head 26 places powder into the mold groove 603, the movement and transmission between the bottom of the plate conveyor belt 4 and the top of the workbench 1 generates a slight vibration under the action of the rough surface, facilitating the stabilization of the metal powder's position. Furthermore, the rough surface area is small and will not affect the subsequent smoothing by the agitator plate 28 or the subsequent scraping. The sliding support between the conveyor belt 4 and the worktable 1 facilitates forging support for the lower mold 6 and the upper mold 22 at the stamping position. The plate conveyor belt 4 is driven stepwise by the power transmission mechanism 5. The power transmission mode is to rotate one notch and stop, which facilitates dynamic stepwise operation and increases production efficiency. The mounting plate 605 is installed on the top of the plate conveyor belt 4 with bolts, which is convenient for disassembly and assembly. The lower molds 6 of multiple mold slots 603 with different shapes can be disassembled and installed on the top of the plate conveyor belt 4 through the mounting plate 605, which increases the flexibility and makes it easy to change the molds according to production needs, thereby facilitating the powder forming of small metal parts.

[0034] In another implementation scheme, such as Figures 1-7 As shown, the outer side of the slide plate 12 is slidably mounted on the outer side of the support column 10. The output end of the electro-hydraulic cylinder 13 moves through and extends to the bottom of the top plate 11. The upper molds 22 are linearly and evenly distributed on the bottom of the slide plate 12. The specifications and dimensions of the upper molds 22 are adapted to the specifications and dimensions of the mold groove 603. The lengths of the three upper molds 22 are distributed from short to long, and the length difference of the three upper molds 22 is within the range of 10%.

[0035] The slide plate 12 slides on the outside of the support column 10 for limiting its movement, facilitating stable movement, ensuring forging accuracy and stable structural force. The upper die 22 is bolted to the bottom of the slide plate 12, facilitating the replacement of upper dies 22 with different specifications, and making it easy to adapt to the die groove 603. This allows for easy replacement according to different production needs. The multiple upper dies 22 are distributed from short to long. The first upper die 22 and the first die groove 603 are forged with slightly shorter lengths, and the subsequent upper dies 22 are gradually extended. The length difference of the multiple upper dies 22 is within 10%, which limits the compression ratio during cold forging, reduces damage, and ensures stability when the upper die 22 and the die groove 603 press the powder together, increasing the yield.

[0036] In another implementation scheme, such as Figures 1-7As shown, the inner mold 602 is fixedly installed at the bottom of the inner cavity of the outer ring 601, the hollow support frame 608 is fixedly installed at the bottom of the inner cavity of the mold groove 603, the sealing piston 607 is movably sleeved inside the mold groove 603, the connecting groove 610 is opened inside the inner mold 602, the sealing piston 609 and the pressing column 604 are both movably sleeved inside the connecting groove 610, the pressing column 604 movably passes through the outer ring 601 and extends to the outside of the outer ring 601, the opposite sides of the mold groove 603 and the connecting groove 610 are filled with hydraulic oil, the position of the output end of the electro-hydraulic rod 25 corresponds to the position of the pressing column 604, and both the outer ring 601 and the inner mold 602 are circular.

[0037] The cavity between the outer ring 601 and the inner mold 602 facilitates airflow and provides temporary storage space for excess metal powder. The hollow support frame 608 supports the top sealing piston 607 and the mold groove engaging column 606, ensuring the compression support position of the sealing piston 607 and the mold groove engaging column 606 while hydraulic oil passes through. The sealing piston 607 and the sealing piston 609 limit the internal hydraulic oil and transmit the movement effect through the hydraulic oil. After the upper mold 22 and the mold groove 603 finish forging the metal powder, the lower mold 6 moves to the output end of the electro-hydraulic rod 25. At this time, the electric... The hydraulic rod 25 extends to press the pressing column 604, which in turn moves the sealing piston 609. Through the hydraulic oil in the connecting groove 610 and the mold groove 603, the sealing piston 607 and the mold groove engaging column 606 are pushed upward, pushing a portion of the formed metal part out of the mold groove 603. Then, the operator manually removes the formed metal part and presses the mold groove engaging column 606 and the sealing piston 607 downward to reset them. The operation is simple, optimizes the operator's operation process and steps, reduces the operator's involvement in the process, increases efficiency, and reduces the operator's labor intensity.

[0038] In another implementation scheme, such as Figures 1-6 As shown, the powder metering pump 17 is fixedly installed at the bottom of the top plate 11 by a horizontal bracket, and the size of the flexible guide head 26 is compatible with the size of the mold groove 603.

[0039] The powder metering pump 17 is fixed by a support structure. When the powder metering pump 17 pumps out metal powder, the output pipe 18 and the flexible guide head 26 guide the metal powder to form a slightly protruding conical pile on the top of the mold groove 603. This facilitates the subsequent leveling by the first scraper 30 and the removal by the second scraper 31, thereby facilitating the leveling of the metal powder and the subsequent forging operation.

[0040] In another implementation scheme, such as Figures 1-9As shown, three suction heads 35 are fixedly installed on one side of the top of the workbench 1. The bottom of the three suction heads 35 is connected to the suction pipe 24. The bottom of the suction pipe 24 is connected to the filter cartridge 20. The filter cartridge 20 is equipped with a dust filter bag 33. The bottom of the dust filter bag 33 is connected to the sealing tube 34. The outside of the sealing tube 34 is connected to the guide pipe 32. The bottom of the guide pipe 32 is connected to the sealing tank 19. The filter cartridge 20 is fixedly installed on the inside of the base support 2. The sealing tube 34 is sealed and inserted into the bottom of the guide pipe 32. The guide pipe 32 is fixedly inserted through the base support 2 and connected to the inside of the sealing tank 19. One side of the bottom of the filter cartridge 20 is connected to the suction pump 21 through a pipe. The suction pump 21 is fixedly installed on the inside of the base support 2.

[0041] When the plate conveyor belt 4 and the lower mold 6 drive the air suction pipe 7 and the silicone flexible cover 8 to move, the silicone flexible cover 8 and the air suction head 35 correspond. At this time, the air suction pump 21 starts, generating airflow suction on the filter cartridge 20 and the suction pipe 24. Through the insertion effect of the air suction head 35 and the silicone flexible cover 8, the metal powder and airflow on the outer ring 601 and the inner side of the inner mold 602 are extracted through the air suction pipe 7, and guided into the suction pipe 24 through the air suction pipe 7 and the air suction head 35. The airflow is guided into the filtration range of the dust filter bag 33. The metal powder accumulates under the filtration of the dust filter bag 33. The airflow is discharged through the suction pump 21. The metal powder, under the accumulation of the dust filter bag 33, is guided through the sealed insertion tube 34 and then through the guide tube 32 to be collected inside the sealed container 19. This makes it easy to collect the excess scraped and flattened metal powder, which can be added back into the powder placement cylinder 14 later. This reduces the difficulty of manual collection, increases the use effect, and facilitates recycling.

[0042] In another implementation scheme, such as Figures 1-9 As shown, the suction pipe 7 is fixed to the top of the plate conveyor belt 4 by a bracket. The size of the suction head 35 is compatible with the size of the silicone flexible cover 8. The suction head 35 is nozzle-shaped, and the silicone flexible cover 8 is trumpet-shaped. The position of the suction head 35 corresponds to the position of the silicone flexible cover 8.

[0043] When the plate conveyor belt 4 is driven, the suction pipe 7 follows the plate conveyor belt 4 and the lower mold 6, causing the suction pipe 7 and the silicone flexible cover 8 to move gradually. As it moves, the silicone flexible cover 8 is deformable and deforms after being squeezed by the suction head 35. After stopping, the silicone flexible cover 8 and the suction head 35 are aligned, forming a cone and flared mouth insertion effect. This facilitates the negative pressure suction force generated by the suction pipe 24 and the suction head 35, causing the silicone flexible cover 8 to deform and fit against the outside of the suction head 35. The silicone flexible cover 8 and the suction pipe 7 guide the airflow, causing the airflow and metal powder inside the outer ring 601 to be discharged, which facilitates the extraction of metal powder from the mobile phone.

[0044] In another implementation scheme, such as Figures 1-6 As shown, the toggle plate 28 is evenly distributed around the outer side of the output shaft of the reduction servo motor 27. The first scraper 30 and the second scraper 31 are relatively inclined. The bottom of the second scraper 31 is closely attached to the top of the outer ring 601 and the inner mold 602. The bottom of the first scraper 30 is separated from the top of the outer ring 601 and the inner mold 602 by a certain gap. The tops of the outer ring 601 and the inner mold 602 are flush.

[0045] When the powder metering pump 17 pumps out metal powder, the output pipe 18 and the flexible guide head 26 guide the metal powder to form a slightly protruding conical pile at the top of the mold groove 603. The decelerated servo motor 27 drives the actuating plate 28 to rotate slowly, gradually flattening the metal powder pile and making it higher than the top of the inner mold 602. Then, the first scraper 30 flattens and squeezes the powder, and the second scraper 31 completely adheres and squeezes it to remove the powder, completely flattening the metal powder inside the mold groove 603. This reduces the tediousness of manual flattening by operators, and the multiple gradual flattenings reduce the labor intensity of operators and increase the efficiency of use.

[0046] In another implementation scheme, such as Figures 1-4 As shown, a control console 3 is fixedly installed on the top of the workbench 1, and the positions of the three infrared sensors 23 correspond to the positions of the lower mold 6.

[0047] The control console 3 is an intelligent control device, equipped with a PLC programmable logic controller and human-machine interaction and communication components. It has a built-in control system, which facilitates the control of the equipment to perform operations and control the operation step by step. The control output terminal of the control console 3 is electrically connected to the input terminals of the conveying power mechanism 5, the electro-hydraulic cylinder 13, the screw conveyor pump 15, the powder metering pump 17, the suction pump 21, the electro-hydraulic rod 25, and the geared servo motor 27 through wires.
