Abstract
Description
Technical Field
[0001] This invention relates to the field of alloy powder press technology, specifically to a processing device for cemented carbide drill bits. Background Technology
[0002] Alloy powder presses are core equipment in the powder metallurgy industry, primarily used to press metal or alloy powders into green blanks of specific shapes and densities under high pressure. In the manufacturing process of precision tools such as carbide drill bits, the performance of the press directly determines the dimensional accuracy, density uniformity, and mechanical strength of the product.
[0003] The patent CN117340245B, entitled "Alloy Powder Extrusion Molding Apparatus and Method," focuses on promoting powder particle rearrangement through vibration transmission, thereby increasing the compactness of the powder before pressing. However, this patent has several substantial unresolved issues: First, vibration alone cannot guarantee a smooth powder surface within the cavity; second, vibration causes powder to splash outwards from the cavity; and third, since existing technologies also generate excess powder scattered around the cavity when alloy powder is added, this patent lacks a powder collection structure, resulting in excess powder scattering outside the cavity and being unable to be cleaned and recycled in a timely manner. Summary of the Invention
[0004] A processing device for cemented carbide drill bits includes a press body, which includes an upper mold and a lower mold. The upper mold and the lower mold are respectively installed at the top and bottom of the press body. A support plate is fixedly connected to the middle of the press body. A mold is installed on the support plate. A processing component is provided on the support plate. The processing component includes a leveling component, a vibration component, and a collecting component. The leveling component is used to level the alloy powder in the mold cavity and push the pressed blank away from the press body. The vibration component is used to adjust the optimal position to apply vibration to the alloy powder or the pressed blank in the mold. The collecting component is used to collect and reuse excess alloy powder. The leveling component includes two side panels and a scraper, with the scraper fixedly connected to one side of the two side panels that are close to each other, and the bottom of the scraper is set as a pointed tip; the vibration component includes a small vibrator, with the bottom vibration end of the small vibrator in contact with the top surface of the support plate; the collection component includes a filter screen and a storage tube, with the filter screen used to filter the alloy powder and discharge it into the storage tube, and the storage tube used to store the alloy powder.
[0005] Furthermore, the leveling component also includes a discharge plate, which is fixedly connected to the bearing plate. Side plate one and side plate two are fixedly connected to the side of the discharge plate away from the press body. Side plate two extends to the top of the bearing plate. A synchronous belt mechanism is provided on side plate two, wherein the synchronous belt of the synchronous belt mechanism is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the connecting rod. A guide block is slidably connected to the second side plate. A straight groove is opened on the guide block. The connecting rod is slidably connected to the straight groove. A moving plate is fixedly connected to the connecting rod.
[0006] Furthermore, the synchronous belt mechanism includes two pulleys symmetrically rotated on the second side plate. Both ends of the pulleys pass through the second side plate. The ends of the two pulleys closest to the first side plate are connected to a synchronous belt. A small servo motor is fixedly connected to the side of the second side plate away from the first side plate. The small servo motor has a fixed end and an output shaft. The output shaft end of the small servo motor is fixedly connected to the pulley on the side closest to the unloading plate.
[0007] Furthermore, two transverse grooves are symmetrically opened on the second side plate, and a guide block is slidably connected to the two transverse grooves. The guide block is located on the side of the second side plate closer to the first side plate, and a straight groove is opened on the guide block. A rotating shaft is fixedly connected to the side of the synchronous belt away from the second side plate. A connecting rod is rotatably connected to the end of the rotating shaft away from the synchronous belt. A moving plate is fixedly connected to the end of the connecting rod away from the rotating shaft. The two side plates are symmetrically rotatably connected to the bottom of the moving plate. A torsion spring is sleeved on each of the two side plates, and the two ends of the torsion spring are fixedly connected to the moving plate and the side plate, respectively.
[0008] Furthermore, the vibrating component also includes a slider, which is slidably connected to the top of the transfer plate. A connecting plate is fixedly connected to the side of the slider near the unloading plate. A threaded rod is threadedly connected to the top of the slider, and the bottom end of the threaded rod is pressed into the top surface of the transfer plate. A small vibrator is fixedly connected to the bottom of the connecting plate on the side away from the slider.
[0009] Furthermore, the collection components also include a bottom cover plate, which is detachably installed at the bottom of the storage tube by bolts. The filter screen is fixedly connected to the unloading plate, and the filter screen is flush with the upper surface of the unloading plate. The storage tube is fixedly connected to the bottom of the unloading plate at the position corresponding to the filter screen. A small fan is installed inside the bottom cover plate, and the operation of the small fan draws suction to generate suction in the storage tube.
[0010] Furthermore, the side of the unloading plate away from the press body is set to be inclined, and the inclined surface of the unloading plate is provided with anti-slip texture made of rubber.
[0011] Furthermore, the connecting rod is square, and the two side panels protrude from the scraper on the side near the unloading plate.
[0012] Compared with the prior art, the beneficial effects of the present invention are: Firstly: By operating the processing components, scraping and vibration are performed simultaneously before mold closing. Scraping ensures accurate alloy powder filling and a smooth surface, while high-frequency vibration effectively eliminates air gaps between alloy powder particles, making them more compact. This ensures uniform distribution and consistent density of alloy powder within the cavity, reducing internal defects caused by uneven density and laying the foundation for a more uniform density distribution in subsequent pressing.
[0013] Secondly: By operating the processing components, excess alloy powder around the cavity can be actively pushed to a designated area and promptly recovered with the help of wind adsorption, thus preventing excess powder from entering the pressing mold surface and improving the dimensional accuracy and surface finish of the pressed product.
[0014] Thirdly: By operating the processing components, a small, position-adjustable vibrator was designed, which enables vibration to be transmitted more directly and efficiently to the inside of the powder. It can also be positioned specifically for cavities of different pressing sizes, thereby improving the versatility of the processing components.
[0015] Fourthly: By operating the processing components, targeted vibrations were designed after mold opening, which can loosen the physical adhesion and adsorption force between the inner wall of the cavity and the pressed product. At the same time, the flattening structure can be used to push the pressed product away for collection, realizing a fully automated closed loop from powder filling, flattening, pressing, demolding to finished product collection. This reduces manual intervention and handling links, and lowers the uncertainty or potential safety risks caused by manual operation. Attached Figure Description

Detailed Implementation
[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0019] Reference Figures 1 to 9 As shown, a processing device for cemented carbide drill bits includes a press body 11. The press body 11 includes an upper mold 12 and a lower mold 13. The upper mold 12 and the lower mold 13 are respectively installed at the top and bottom of the press body 11. A support plate 14 is fixedly connected to the middle of the press body 11, and a mold 15 is installed on the support plate 14.
[0020] The structure of the press body 11, upper mold 12, lower mold 13, bearing plate 14, and mold 15 are all existing known technologies. The lower surface of the upper mold 12 is provided with an upper punch, the upper surface of the lower mold 13 is provided with a lower punch, and the mold 15 has a cavity. The upper and lower punches are coaxial with the cavity. The operation of the upper mold 12 and the lower mold 13 is preset according to the control system of the press body 11.
[0021] It should be noted that the control system of the press body 11 is a known existing technology, and will not be described in detail here.
[0022] In the prior art, the press body 11 is equipped with a feeder to fill the cavity of the mold 15 with alloy powder. During pressing, the lower punch blocks the bottom of the cavity of the mold 15, and the feeder fills the cavity with alloy powder. Then, under the control of the control system of the press body 11, the upper and lower punches move synchronously in opposite directions, forming bidirectional pressing of the alloy powder in the cavity, so that the alloy powder forms a dense pressed blank. After pressing is completed, both the upper and lower punches move upward, and the lower punch pushes the pressed blank out of the cavity of the mold 15 to achieve demolding. After completion, the lower punch moves downward to the loading position to repeat the next cycle of alloy powder pressing.
[0023] The support plate 14 is equipped with a processing component, which includes a leveling component, a vibration component, and a collection component.
[0024] The leveling component is used to level the alloy powder in the cavity of mold 15 and to push the finished pressed billet away from the press body 11.
[0025] The leveling component includes a discharge plate 21, which is fixedly connected to the support plate 14. Side plate 22 and side plate 23 are fixedly connected to the side of the discharge plate 21 away from the press body 11. Side plate 23 extends to the top of the support plate 14. Two pulleys 24 are symmetrically rotatably connected to side plate 23, with both ends of the pulleys 24 passing through side plate 23. The ends of the two pulleys 24 closest to side plate 22 are connected to a synchronous belt 25. A small servo motor 26 is fixedly connected to the side of side plate 23 away from side plate 22. The small servo motor 26 has a fixed end and an output shaft. The output shaft end of the small servo motor 26 is fixedly connected to the pulley 24 closest to the discharge plate 21. Two transverse grooves 27 are symmetrically formed on side plate 23. A guide block 28 is slidably connected to the side plate 23, which is located on the side of the side plate 23 near the side plate 22. A straight groove 29 is provided on the guide block 28. A rotating shaft 210 is fixedly connected to the side of the synchronous belt 25 away from the side plate 23. A connecting rod 211 is rotatably connected to the end of the rotating shaft 210 away from the synchronous belt 25. The connecting rod 211 is slidably connected to the straight groove 29. A shift plate 212 is fixedly connected to the end of the connecting rod 211 away from the rotating shaft 210. Two side plates 213 are symmetrically rotatably connected to the bottom of the shift plate 212. A torsion spring 214 is sleeved on each of the two side plates 213. The two ends of the torsion spring 214 are fixedly connected to the shift plate 212 and the side plate 213 respectively. A scraper 215 is fixedly connected to the side of the two side plates 213 that are close to each other.
[0026] The unloading plate 21 is inclined on the side away from the press body 11. Its function is to guide the pressed product away from the press body 11 through the inclined surface. The inclined surface of the unloading plate 21 is provided with anti-slip texture of rubber material. Its function is to increase friction and prevent the pressed product from being damaged due to excessive discharge speed. At the same time, the softness of the rubber material prevents the pressed product from being bumped during discharge.
[0027] Among them, side plate 1 22 and side plate 23 are used as side enclosures of unloading plate 21 to ensure that the finished pressed billet can only be discharged outward along the inclined surface of unloading plate 21.
[0028] The small servo motor 26 is a known technology. The small servo motor 26 is controlled by the control system of the press body 11.
[0029] Where: Reference Figure 8 and Figure 9As shown, the connecting rod 211 is square, and its function is to ensure that the connecting rod 211 will not deflect when it slides in the straight groove 29.
[0030] Wherein: the bottom of the scraper 215 is set as a pointed tip, and the two side plates 213 protrude from the side of the scraper 215 near the unloading plate 21, the function of which is to prevent the alloy dust scooped up by the scraper 215 from being dispersed to both sides.
[0031] The torsion spring 214 applies downward pressure to the side plate 213 and scraper 215, ensuring that the bottom ends of the side plate 213 and scraper 215 are in close contact with the top surface of the bearing plate 14. It should be noted that when the torsion spring 214 does not undergo elastic deformation, the scraper 215 is inclined towards the discharge plate 21 at the bottom end of the transfer plate 212. This ensures that the tip of the scraper 215 always faces the discharge plate 21, thus ensuring the effective operation of the scraper 215.
[0032] The vibrating component is used to apply vibration to the alloy powder or pressed blank within the mold 15 at the optimal position.
[0033] The vibrating component includes a slider 216, which is slidably connected to the top of the transfer plate 212. A connecting plate 217 is fixedly connected to the side of the slider 216 near the unloading plate 21. A threaded rod 218 is threadedly connected to the top of the slider 216. A small vibrator 219 is fixedly connected to the bottom of the connecting plate 217 on the side away from the slider 216.
[0034] Wherein: the bottom end of the threaded rod 218 is pressed and engaged with the top surface of the sliding plate 212, and its function is: by tightening the threaded rod 218 on the slider 216, the slider 216 can be limited on the sliding plate 212.
[0035] The miniature vibrator 219 is a known technology. The miniature vibrator 219 is controlled by the control system of the press body 11. The vibrating end of the miniature vibrator 219 faces downward, and the bottom vibrating end of the miniature vibrator 219 is in contact with the top surface of the support plate 14.
[0036] The collection component is used to collect and reuse excess alloy powder.
[0037] The collecting component includes a filter screen 220, which is fixedly connected to the unloading plate 21. The filter screen 220 is flush with the upper surface of the unloading plate 21. A storage tube 221 is fixedly connected to the bottom of the unloading plate 21 corresponding to the position of the filter screen 220. A bottom cover plate 222 is detachably installed at the bottom end of the storage tube 221 by bolts. A small fan 223 is installed inside the bottom cover plate 222.
[0038] The function of filter 220 is to filter the alloy powder and discharge it into the storage tube 221.
[0039] The bottom cover plate 222 and the storage tube 221 are detachable so that the bottom cover plate 222 and the small fan 223 can be removed from the bottom of the storage tube 221, thereby exposing the bottom of the storage tube 221.
[0040] Among them, the small fan 223 is a known existing technology, and the small vibrator 219 is controlled by the control system of the press body 11. The small fan 223 is used to generate suction in the storage tube 221, so that the alloy powder on the filter screen 220 can be collected into the storage tube 221.
[0041] In the initial stage of the processing assembly, i.e., before the press body 11 presses the alloy powder, the structural states within the processing assembly are as follows: the guide block 28 is located at the end of the two transverse grooves 27 away from the unloading plate 21; the connecting rod 211 is located at the bottom end of the straight groove 29; the scraper 215 and the side plate 213 are both in contact with the top surface of the bearing plate 14; and the torsion spring 214 undergoes elastic deformation. The threaded rod 218 is threaded onto the slider 216; and the bottom cover plate 222 is bolted to the bottom end of the storage tube 221. The small servo motor 26, the small vibrator 219, and the small fan 223 are not running.
[0042] When the processing component is running, that is, when the press body 11 needs to press the alloy powder, the processing component operates as follows: In the prior art, users can install molds 15 with different cavity sizes on the support plate 14 according to the different sizes of the pressed blanks required. At this time, the user adjusts the position of the small vibrator 219 according to the size of the cavity of the currently installed mold 15, so that the vibration end of the small vibrator 219 can be close to the cavity of the mold 15, thereby allowing the vibration of the small vibrator 219 to be better applied to the alloy powder in the cavity of the mold 15. The specific operation is as follows: The user loosens the threaded rod 218, causing it to stop pressing against the transfer plate 212, allowing the slider 216 to slide on the transfer plate 212. The user then moves the slider 216 closer to the cavity of the mold 15, positioning the small vibrator 219 on the support plate 14 near the cavity of the mold 15, but not overlapping it. After adjustment, the user tightens the threaded rod 218 on the slider 216, pressing it against the transfer plate 212, thus fixing the slider 216 on the transfer plate 212. The position of the small vibrator 219 on the transfer plate 212 is also fixed at this point.
[0043] At this time, the feeder of the press body 11 fills the cavity of the mold 15 with alloy powder. After filling, the feeder is reset. However, in the prior art, as the filling is carried out, the feeder may scatter excess alloy powder on the support plate 14.
[0044] At this time, the user starts the small servo motor 26 and the small vibrator 219 through the control system of the press body 11. The operation of the small servo motor 26 causes its output shaft to rotate. As the output shaft of the small servo motor 26 rotates, it drives the corresponding pulley 24 to rotate synchronously. This pulley 24 drives another pulley 24 to rotate synchronously through the synchronous belt 25. At this time, the synchronous belt 25 transmits power on the two pulleys 24. With the transmission of the synchronous belt 25, the synchronous belt 25 drives the moving plate 212 to move synchronously through the rotating shaft 210 and the connecting rod 211, so that the moving plate 212 moves towards the unloading plate 21.
[0045] During the movement of the transfer plate 212, the small vibrator 219 operates and generates vibration. The vibration generated by the small vibrator 219 as it moves with the transfer plate 212 can be transmitted to the alloy powder in the cavity of the mold 15. The high-frequency vibration can effectively eliminate the gaps between the alloy powder particles, making the alloy powder in the cavity of the mold 15 more compact.
[0046] As the transfer plate 212 moves, it simultaneously drives the scraper 215 to move as well. Under the elastic action of the torsion spring 214, the bottom tip of the scraper 215 and the two side plates 213 always maintain a close contact with the top surface of the support plate 14. As the transfer plate 212 moves, the alloy powder scattered on the support plate 14 will be pushed and moved synchronously by the scraper 215. The scraper 215 can also scrape the alloy powder in the cavity of the mold 15 flat, thereby ensuring that the alloy powder filling amount in the cavity of the mold 15 is accurate and the surface is flat.
[0047] During the vibration and scraping process, excess alloy powder will splash out of the cavity of mold 15 and be pushed away from the cavity by scraper 215. Scraper 215 will push the splashed alloy powder and the scraped excess alloy powder towards the unloading plate 21. During this process, the two side plates 213 can prevent the pushed alloy powder from moving to the sides, ensuring that the excess alloy powder can be pushed to the top surface of unloading plate 21 by scraper 215.
[0048] When the scraper 215 pushes excess alloy powder to the position of the filter screen 220 on the discharge plate 21, the alloy powder falls downward through the gaps in the filter screen 220. At the same time, the small fan 223 is started under the control of the control system of the press body 11, generating suction in the direction of the filter screen 220, attracting and collecting the excess powder pushed by the scraper 215 into the storage tube 221. At the same time, it can also remove the alloy powder adhering to the scraper 215 and the side plate 213.
[0049] At this time, the transfer plate 212 moves to the end of the synchronous belt 25 near the unloading plate 21. With the continuous transmission of the synchronous belt 25, the transfer plate 212 tends to be driven upward and flipped by the synchronous belt 25. However, since the transfer plate 212 slides in the straight groove 29 through the connecting rod 211, the transfer plate 212 can only move vertically in the straight groove 29. Thus, the transfer plate 212 will move to the top position of the synchronous belt 25 and keep the vibrating end of the small vibrator 219 always facing downward. At this time, the scraper 215 and the side plate 213 no longer contact the bearing plate 14. With the transmission of the synchronous belt 25, the transfer plate 212 moves away from the unloading plate 21 until the transfer plate 212 moves to the end of the synchronous belt 25 away from the unloading plate 21. Then, the transfer plate 212 moves vertically downward again until the scraper 215 is in contact with the bearing plate 14. At this time, the control system of the press body 11 stops the operation of the small servo motor 26 and the small vibrator 219. At this point, the alloy powder in the cavity of mold 15 is compacted and leveled, and excess alloy powder is pushed away from the support plate 14 and collected.
[0050] At this time, the press body 11 can press the alloy powder. Under the control of the press body 11 control system, the upper and lower punches move synchronously in opposite directions to form bidirectional pressing of the alloy powder in the cavity, so that the alloy powder forms a dense pressed blank finished product.
[0051] It should be noted that in the prior art, when the upper punch is pressing, the upper die 12 is not fully inserted into the cavity of the die 15. There is a gap at the top of the support plate 14 except for the position of the die 15, and the side plate 23, the sliding plate 212 and other structures are all located in this gap. The purpose is to prevent the position of the side plate 23, the sliding plate 212 and other structures from interfering with the pressing work.
[0052] After pressing is completed, both the upper and lower punches move upwards. The lower punch pushes the pressed blank product out of the cavity of the mold 15 to achieve demolding. During this operation, the small vibrator 219 is activated by the control system of the press body 11 to transmit vibration to the pressed blank product in the mold 15, thereby helping the pressed blank product to be demolded.
[0053] After the pressed billet is removed from the cavity of the mold 15, the control system of the press body 11 drives the small servo motor 26 to run, thereby causing the transfer plate 212 to move towards the unloading plate 21. During the movement, the transfer plate 212 can push the pressed billet towards the unloading plate 21 through the scraper 215 until the pressed billet moves onto the unloading plate 21 and is discharged downward along the slope of the unloading plate 21. At this time, the anti-slip texture of the rubber material on the unloading plate 21 can increase the friction and prevent the pressed billet from being damaged due to excessive discharge speed. At the same time, the softness of the rubber material can prevent the pressed billet from being bumped during discharge.
[0054] After the material is discharged, with the continuous transmission of the synchronous belt 25, the transfer plate 212 returns to the side of the second side plate 23 away from the unloading plate 21, and when the scraper 215 contacts the support plate 14, the small servo motor 26 stops operating, limiting the transfer plate 212. At this point, the pressing of the alloy powder is completed. The user can repeat the above operation to achieve continuous alloy powder pressing.
[0055] Furthermore, users can remove the alloy powder collected in the storage tube 221 by unloading the bottom cover plate 222 from the bottom of the storage tube 221 and reuse it.
[0056] In summary, the following beneficial effects can be achieved during the operation of the processing components: Firstly: By operating the processing components, scraping and vibration are performed simultaneously before mold closing. Scraping ensures accurate alloy powder filling and a smooth surface, while high-frequency vibration effectively eliminates air gaps between alloy powder particles, making them more compact. This ensures uniform distribution and consistent density of alloy powder within the cavity, reducing internal defects caused by uneven density and laying the foundation for a more uniform density distribution in subsequent pressing.
[0057] Secondly: By operating the processing components, excess alloy powder around the cavity can be actively pushed to a designated area and promptly recovered with the help of wind adsorption, thus preventing excess powder from entering the pressing mold surface and improving the dimensional accuracy and surface finish of the pressed product.
[0058] Thirdly: By operating the processing components, a small, position-adjustable vibrator 219 was designed, which enables vibration to be transmitted more directly and efficiently to the inside of the powder. It can also be positioned specifically for cavities of different pressing sizes, thereby improving the versatility of the processing components.
[0059] Fourthly: By operating the processing components, targeted vibrations were designed after mold opening, which can loosen the physical adhesion and adsorption force between the inner wall of the cavity and the pressed product. At the same time, the flattening structure can be used to push the pressed product away for collection, realizing a fully automated closed loop from powder filling, flattening, pressing, demolding to finished product collection. This reduces manual intervention and handling links, and lowers the uncertainty or potential safety risks caused by manual operation.
