Description

Technical Field

[0001] The present invention relates to the technical field of metal powder processing, and in particular to an intelligent cold pressing and drying device and method based on metal powder processing. Background Art

[0002] Metal powders are often mixed with liquids. When the metal powders are recycled later, they need to be dehydrated to achieve a specific drying effect.

[0003] The patent application with reference publication number CN109175385A discloses an extrusion dehydration device for metal powder blocks, comprising a support plate and an extrusion box, support legs are arranged on both sides of the lower end of the support plate, a support one and a support two are arranged on both sides of the upper end of the support plate, a slide rail is arranged in the middle of the upper end of the support plate, a reciprocating drive device is arranged in the middle of the lower end of the support plate, a connecting frame is arranged between the reciprocating drive device and the bottom of the extrusion box for fixed connection, the support one and the support two are both C-shaped structures, a guide rod is fixed on the inner side of the support one, a screw rod seat is fixed on the inner side of the support two, a screw rod is arranged in the screw rod seat, a servo motor is arranged on the upper end of the support two, a cross plate two and a cross plate one which are threadedly connected are arranged on the screw rod from top to bottom, a cylinder is fixed on the upper end of the cross plate two, a piston rod of the cylinder passes through the cross plate two and is connected to a fixed plate, a plurality of pressure strips are arranged below the fixed plate, a pressing plate is arranged at a lower end of the cross plate, and a plurality of pressure strip holes are arranged on the pressing plate, the device is dehydrated after multiple extrusions, the dehydration effect is good, the water content of the powder blocks after treatment is low, and the subsequent processing is convenient.

[0004] When metal powder is subjected to unidirectional pressure in the cylinder, it is easy to form static accumulation due to the friction between particles, inducing the "particle bridging effect" (that is, the powder forms a stable arch structure, hindering the flow of materials). Existing technologies mostly rely on mechanical vibration or gas backblowing to break the accumulation, but vibration can easily lead to powder segregation, and backblowing requires shutdown operation, resulting in reduced efficiency. In addition, if the metal powder has poor fluidity, local dead corners are easily generated during extrusion, resulting in a high moisture content of the filter cake in some areas, and even a "hard shell" phenomenon, which hinders the discharge of internal moisture.

[0005] Therefore, it is necessary to provide an intelligent cold pressing and drying device and method based on metal powder processing to solve the above technical problems. Summary of the invention

[0016] An intelligent cold pressing and drying method based on metal powder processing comprises the following steps: Step 1: Push two extrusion pieces into the two ends of the extrusion barrel through the telescopic ends of two hydraulic telescopic rods, and inject the slurry with metal powder between the two filter plates through the liquid spraying pipe fittings; Step 2: The extrusion piece is continuously pushed by the hydraulic telescopic rod, so that the filter plate squeezes the slurry and filters the metal through the filter plate; Step 3: During the extrusion process, the driving device drives the rotating cylinder to rotate, so that the electromagnet plates on the multiple fixed plates outside the rotating cylinder rotate, and the electromagnet plates after power-on drive the metal powder to be dynamically stirred through electromagnetic force.

[0018] 2. The insulating plate is used to insulate the magnetic attraction of the electromagnet plate, so that the extruded metal powder changes during the rotation of the magnetic attraction, driving the metal powder to move inside the extrusion cylinder, breaking the static accumulation state. The periodic shielding of the insulating plate causes the magnetic field intensity to produce sinusoidal fluctuations, inducing a directional-disordered alternating motion mode of the powder to prevent local agglomeration.

[0019] 3. After the metal powder passes through the filter plate, it will inevitably be adsorbed on the electromagnet plate and accumulated, forming a magnetic-liquid double interception layer between the filter plate and the electromagnet plate. When the metal powder passes through the filter plate with the liquid, the electromagnet plate is energized to generate a directional magnetic field to adsorb and capture the magnetic metal powder.

[0020] 4. Close the metal powder inside the collection frame. Later, when the extrusion is completed, the personnel can remove the cover block on the filter plate to discharge the metal powder inside the collection frame to avoid disassembly of the filter plate. The real-time matching of the magnetic field strength and the scraping action solves the industry problems of static filtration being easily blocked and dynamic processing powder escaping.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] like Figures 1 to 13 As shown, an intelligent cold pressing and drying device and method based on metal powder processing includes the following embodiments: Embodiment 1: Figures 1 to 6 As shown, it includes two frames 1, a plurality of guide rods 101 are fixedly connected between the two frames 1, an extrusion cylinder 102 is fixedly connected between the plurality of guide rods 101, and also includes: Two extrusion members 2 are arranged opposite to each other, and the two extrusion members 2 are respectively arranged at both ends of the extrusion barrel 102. The two frames 1 are fixedly connected with hydraulic telescopic rods 103 inside, and the telescopic ends of the two hydraulic telescopic rods 103 are respectively fixedly connected with the two extrusion members 2. The two extrusion members 2 are fixedly connected with a processing frame 200 on the opposite side, and the front side of the processing frame 200 is fixedly connected with a filter plate 202 for filtering. The two extrusion members 2 are provided with a rotating barrel 4 inside, and are rotatably connected with the processing frame 200 and the filter plate 202. A liquid spraying pipe is arranged inside one of the rotating barrels 4. A flow hole is arranged between the extrusion member 2 and the processing frame 200 for discharging the liquid. The position of the flow hole is not specifically limited. A plurality of fixed plates 401 are fixedly connected to the outside of the rotating cylinder 4, and the plurality of fixed plates 401 are arranged inside the processing frame 200. The plurality of fixed plates 401 are fixedly connected to an electromagnet plate 402 close to the side of the rotating cylinder 4. The electromagnet plate 402 generates magnetic adsorption on the metal powder when energized. A driving device for driving the rotating cylinder 4 to rotate is arranged at one end of the rotating cylinder 4 away from the extrusion member 2. The driving device can be achieved by arranging a driving motor on the outside of the extrusion member 2, and the rotating cylinder 4 is rotated through the output shaft of the driving motor and the pulley belt.

[0027] The liquid spraying pipe comprises a spraying pipe 3, which is arranged inside the rotating cylinder 4 and movably connected to the rotating cylinder 4. An electric telescopic rod is arranged outside the spraying pipe 3 for pushing the spraying pipe 3 to move.

[0028] An insulating plate 6 for insulating and shielding the electromagnet plate 402 is disposed on one side of the plurality of fixed plates 401 . A transmission member is disposed inside the processing frame 200 , and the insulating plate 6 is driven to reciprocate on one side of the electromagnet plate 402 by the transmission member.

[0029] In the specific implementation, the telescopic ends of the two hydraulic telescopic rods 103 are used to push the two extrusion pieces 2 into the two ends of the extrusion barrel 102, and the slurry containing metal powder is injected between the two filter plates 202 through the liquid spraying pipe. The hydraulic telescopic rods 103 continuously push the extrusion pieces 2, so that the filter plates 202 extrude the slurry, and the metal is filtered through the filter plates 202. During the extrusion process, the driving device drives the rotating barrel 4 to rotate, so that the electromagnet plates 402 on the multiple fixed plates 401 outside the rotating barrel 4 rotate, and the electromagnet plates 402 after being energized drive the metal powder to be dynamically stirred through the electromagnetic force, and the rotating barrel 4 is started to make it It rotates circumferentially at a rate of 20-60rpm, with the fixed plate 401 and the electromagnet plate 402 moving synchronously; a pulse width modulation current PWM frequency of 1-5kHz is applied to the electromagnet plate 402 to generate an alternating gradient magnetic field of 0.5-1.2T, driving the metal powder to form a three-dimensional disturbance in the extrusion cylinder 102, and the magnetic field disturbance forms a synergistic effect. During the extrusion process, the metal powder is driven by the Lorentz force generated by the alternating magnetic field, which effectively overcomes the particle bridging effect of the traditional cold pressing process. The particle bridging effect refers to the phenomenon that the powder or granular material forms a stable arch structure due to the interaction between particles during the accumulation and flow process, resulting in the material being unable to flow normally.

[0030] In this embodiment, Figures 5 to 9 As shown, the transmission parts include: A fixed ring frame 5, the fixed ring frame 5 is fixedly connected to the inside of the processing frame 200, and a rotating ring 501 is rotatably connected to the inside of the fixed ring frame 5, and a bevel gear ring 502 is fixedly connected to the inside of the fixed ring frame 5; Reciprocating screw rods 701 corresponding to the plurality of fixed plates 401, both ends of the plurality of reciprocating screw rods 701 are rotatably connected to the rotating cylinder 4 and the rotating ring 501, one end of the reciprocating screw rods 701 extends to the inside of the fixed ring frame 5, one end of the reciprocating screw rods 701 is fixedly connected to a bevel gear 702, and the bevel gear 702 is meshedly connected to the bevel gear ring 502; The sliding seat 703 is sleeved on the outside of the reciprocating screw 701 and connected to the reciprocating screw 701 through a ball nut. The sliding seat 703 is slidably connected to the fixed plate 401 , and a sliding member is provided between the sliding seat 703 and the insulating plate 6 .

[0031] In specific implementation, when the rotating cylinder 4 rotates and drives the multiple annular fixedly connected fixed plates 401 to rotate, the reciprocating screw 701 is also driven to rotate. The reciprocating screw 701 is connected by a bevel gear 702 fixedly connected at one end. The bevel gear 702 is arranged inside the fixed ring frame 5 and meshes with the bevel gear ring 502 inside the fixed ring frame 5, and then the reciprocating screw 701 is driven to rotate through the bevel gear 702. The sliding seat 703 outside the reciprocating screw 701 is reset on the outside of the fixed plate 401, and the insulating plate 6 is driven to reset on the fixed plate 401 through the sliding member. The insulating plate 6 is used to insulate the magnetic attraction of the electromagnet plate 402, so that the extruded metal powder changes during the rotation of the magnetic attraction, driving the metal powder to move and change inside the extrusion cylinder 102, breaking the static stacking state. The periodic shielding of the insulating plate 6 causes the magnetic field intensity to produce sinusoidal fluctuations, inducing a directional-disordered alternating motion mode of the powder to prevent local agglomeration.

[0032] Embodiment 2: Figures 8 to 10 As shown, the sliding member includes: The limiting plate 704 is fixedly connected between the rotating cylinder 4 and the rotating ring 501, and the limiting plate 704 has circular grooves 705 on both sides; The side plates 708 are fixedly connected to the sliding seat 703 on both sides, and the connecting plates 706 are fixedly connected to the insulating plate 6 on both sides. The connecting plates 706 penetrate the side plates 708 and are slidably connected to the side plates 708. The connecting plates 706 are fixedly connected to the side close to the limit plate 704 with a connecting shaft 707. The connecting shaft 707 extends to the inside of the circular groove 705 and slidably cooperates with the limit plate 704.

[0033] A collecting frame 8 for collecting powder is fixedly connected to one end of each of the fixing plates 401 . The collecting frame 8 fits the filter plate 202 , and a cover block 203 is fixed to the outside of the filter plate 202 by bolts. A scraper 601 is fixedly connected to one end of the insulating plate 6 close to the collecting frame 8 .

[0034] In specific implementation, when the metal powder is extruded, a small amount of metal powder will inevitably pass through the filter plate 202, causing the loss of metal powder. In this solution, an electromagnet plate 402 is set on one side of the filter plate 202. When the metal powder passes through the filter plate 202, it will inevitably be adsorbed on the electromagnet plate 402 for accumulation, forming a magnetic-liquid double interception layer between the filter plate 202 and the electromagnet plate 402. When the metal powder passes through the filter plate 202 with the liquid, the electromagnet plate 402 is powered on to generate a directional magnetic field, which adsorbs and captures magnetic metal powders such as iron, cobalt, and nickel-based alloys, while non-magnetic powders are retained in the pores of the filter plate 202 due to the surface tension of the liquid. The collecting frame 8 is fixedly connected to the fixing plate 401. When the insulating plate 6 is attached to the electromagnet plate 402, Fig. 9As shown, the scraper 601 fixedly connected to one end of the insulating plate 6 will push the metal powder adsorbed on the electromagnet plate 402. Under the action of the sliding seat 703, the powder at the front end of the scraper 601 is pushed into the collecting frame 8 for collection, and the personnel can clean it later. When the insulating plate 6 is away from the collecting frame 8, the connecting plate 706 moves along the trajectory of the meandering groove 705 through the meandering groove 705 opened on the limiting plate 704. At this time, the scraper 601 is separated from the electromagnet plate 402. When it moves to the end of the electromagnet plate 402 away from the collecting frame 8, it continues to fit with the electromagnet plate 402 under the action of the meandering groove 705, thereby collecting the metal powder and avoiding the situation where the metal powder on the rear side of the scraper 601 cannot be pushed into the collecting frame 8.

[0035] In this embodiment, Fig.11 and Fig.12 As shown, the collecting frame 8 is provided with an opening at one end close to the insulating plate 6 , a sealing plate 801 for sealing the opening is slidably connected inside the collecting frame 8 , and a first spring 802 is fixedly connected between the sealing plate 801 and the collecting frame 8 .

[0036] Winding discs 805 are provided on both sides of the collecting frame 8, and the two winding discs 805 are rotatably connected to both sides of the fixed plate 401 respectively, and traction ropes 804 are wound and fixed on the outside of the two winding discs 805, and the traction ropes 804 pass through the collecting frame 8 and are fixedly connected to the sealing plate 801, and the first gear 803 is fixedly connected to the outside of the winding disc 805, and first racks 807 are provided on both sides of the fixed plate 401, and the two first racks 807 are fixedly connected to the sliding seat 703, and the two first racks 807 are respectively meshed and connected with the two first gears 803.

[0037] During specific implementation, in order to ensure that the metal powder will not fall out of the collecting frame 8 later when the electromagnet plate 402 is powered off after being inside the collecting frame 8, a sealing plate 801 is provided inside the collecting frame 8 in this scheme. When the sliding seat 703 drives the scraper 601 to approach the collecting frame 8, the first rack 807 fixedly connected to the front of the sliding seat 703 drives the first gear 803 to rotate. The rotation of the first gear 803 drives the traction rope 804 on the outside of the winding disk 805 to reel up, thereby pulling the sealing plate 801 up, so that the scraper 601 can push the metal powder into the collecting frame 8. After the scraper 601 withdraws, the sealing plate 801 is pushed down by the first spring 802 to close the metal powder inside the collecting frame 8. Later, when the extrusion is completed, the personnel can discharge the metal powder inside the collecting frame 8 by removing the cover block 203 on the filter plate 202, avoiding the disassembly of the filter plate 202. The real-time matching of the magnetic field strength and the scraping action solves the industry problems of easy clogging of static filtration and escape of dynamic processing powder.

[0038] It is also provided that the scraping action is automatically completed by the transmission system, and there is no need to stop the machine for manual cleaning. The collection frame 8 adopts a modular quick-release design and is fixed by bolts of the cover block 203. After full load, it can be replaced by an external prompt signal such as a weight sensor.

[0039] Embodiment 3: Fig.13 As shown, two through grooves are provided on the top of the insulating plate 6, and sliding plates 901 are arranged inside the through grooves, and the sliding plates 901 are slidably connected to the insulating plate 6, and multiple cleaning brushes 905 are provided on the top of the two sliding plates 901, and the bottoms of the multiple cleaning brushes 905 are fixedly connected to rotating rods 904, and the rotating rods 904 penetrate the sliding plates 901 and are slidably connected to the sliding plates 901, and the bottoms of the multiple rotating rods 904 are fixedly connected to second gears 906, and second racks 403 are fixedly connected on both sides of the insulating plate 6, and the second racks 403 are meshingly connected to the second gear 906.

[0040] A plurality of second springs 903 are fixedly connected between the two sliding plates 901 and the insulating plate 6 , and a pressing plate 902 is fixedly connected to the top of the sliding plate 901 .

[0041] In specific implementation, when the insulating plate 6 slides on the fixed plate 401, the cleaning brush 905 on the insulating plate 6 will contact the filter plate 202. When the insulating plate 6 moves, the cleaning brush 905 cleans the filter holes on the filter plate 202, and the second gear 906 is engaged with the second rack 403 to rotate the second gear 906, and the second gear 906 drives the fixedly connected rotating rod 904 to rotate, thereby rotating the cleaning brush 905. The cleaning brush 905 uses nylon-carbon fiber composite bristles with a diameter of 0.1-0.3 mm, and its rotation direction is orthogonal to the sliding direction of the insulating plate 6. For example, when the insulating plate moves to the right, the cleaning brush rotates clockwise, forming a "lateral scraping + rotational sweeping" composite cleaning action; When the insulating plate 6 enters the collecting frame 8 along with the scraper 601, the extrusion plate 902 contacts the inner wall of the collecting frame 8, so that the extrusion plate 902 moves toward the middle of the insulating plate 6, and the extrusion plate 902 drives the sliding plate 901 to move in the through groove, thereby causing the cleaning brush 905 to be received inside the insulating plate 6. When the insulating plate 6 slides out of the collecting frame 8, the sliding plate 901 is quickly reset under the push of the second spring 903, thereby vibrating the cleaning brush 905 and shaking off the metal carried by the cleaning brush 905. When the insulating plate 6 exits the collecting frame 8, the second spring 903 releases the stored energy and accelerates the sliding plate 901 to quickly reset, generating an instantaneous impact force to cause the cleaning brush 905 to vibrate at a high frequency, thereby shaking off the metal powder remaining in the gaps between the bristles, and reducing the amount of residual powder attached. At the same time, the cleaning brush 905 also rises with the insulating plate 6, so that the cleaning brush 905 passes through the filter plate 202, changing the cleaning method of the cleaning brush 905. After the cleaning brush 905 is reset, the tip of the bristles passes through the filter holes of the filter plate 202, switching to the "vertical interlacing" cleaning mode, destroying the powder crust layer on the inner wall of the filter hole. When the second gear 906 re-engages with the second rack 403 at a later stage, the elasticity of the second spring 903 automatically compensates for mechanical tolerances during re-engagement to avoid jamming or tooth surface wear.

[0042] The retraction-reset action of the cleaning brush 905 is strictly synchronized with the motion trajectory of the insulating plate 6, and real-time feedback is provided by a position sensor such as a Hall element to ensure that the cleaning brush only penetrates the filter hole in the non-collection stage, thereby controlling the error logically.

[0043] An intelligent cold pressing and drying method based on metal powder processing comprises the following steps: Step 1: Push the two extrusion pieces 2 into the two ends of the extrusion cylinder 102 through the telescopic ends of the two hydraulic telescopic rods 103, and inject the slurry with metal powder between the two filter plates 202 through the liquid spraying pipe; Step 2: The extrusion member 2 is continuously pushed by the hydraulic telescopic rod 103, so that the filter plate 202 extrude the slurry and filter the metal through the filter plate 202; Step 3: During the extrusion process, the driving device drives the rotating cylinder 4 to rotate, so that the electromagnet plates 402 on the multiple fixed plates 401 outside the rotating cylinder 4 rotate, and the electromagnet plates 402 after powering on drive the metal powder to be dynamically stirred by electromagnetic force.
