Description

Technical Field

[0001] The invention relates to the technical field of powder processing, and in particular to a forming device for metal powder processing. Background Art

[0002] Metal powder is a fine granular substance made of metal materials. It is usually obtained by mechanical grinding, chemical reaction or physical methods (such as atomization, gas condensation, etc.). Powder metallurgy is a process technology for preparing metal powder or using metal powder (or a mixture of metal powder and non-metallic powder) as raw material, forming and sintering, to manufacture metal materials, composite materials and various types of products. It is to introduce metal powder into a mold, compact the powder under the action of hydraulic equipment, and then extrude the powder into a shape. Different molds can be used to make metal products of different shapes.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-Figure 9As shown, a forming device for metal powder processing comprises a workbench 1 and a support frame 2 fixedly arranged on the upper end of the workbench 1, a forming cavity 3 is opened on the upper end surface of the workbench 1, an ejection mechanism is arranged inside the forming cavity 3, a first electric push rod 4 is arranged on the upper end of the support frame 2, an extrusion plate 5 matching the forming cavity 3 is arranged at the telescopic end of the first electric push rod 4, a feeding mechanism 6 is arranged on the upper end of the support frame 2, and a conveying component for conveying metal powder to the inside of the forming cavity 3 is arranged on the upper end of the workbench 1;

[0039] The conveying assembly includes a fixed plate 8 arranged at the upper end of the workbench 1 and a material receiving barrel 7 slidably arranged at the upper end of the workbench 1, a filter plate 33 is arranged inside the material receiving barrel 7, a first mounting block 20 is arranged on one side of the material receiving barrel 7, a second mounting block 21 is rotatably arranged on the upper end of the first mounting block 20 through a rotating shaft, a scraping ring 9 for scraping the filter plate 33 is arranged on one side of the second mounting block 21, a mounting groove 37 for sliding the first mounting block 20 and the second mounting block 21 is provided on one side of the fixed plate 8, a notch groove 36 for deflecting the scraping ring 9 is provided at one end of the fixed plate 8, a limiting member for limiting the rotation of the second mounting block 21 is provided inside the first mounting block 20, a driving member for first driving the material receiving barrel 7 and the scraping ring 9 to slide synchronously and then driving the scraping ring 9 to deflect is provided inside the mounting groove 37, and when in use, the driving member Under the action of the driving member, the receiving barrel 7 moves to the bottom of the output end of the feeding mechanism 6 to receive the material, and the feeding mechanism 6 discharges the metal powder into the receiving barrel 7. During this process, the metal powder will be filtered through the filter plate 33, and the metal materials with larger particles will remain on the filter plate 33. Then, under the resetting action of the driving member, the receiving barrel 7 is driven to move to one side of the molding cavity 3, so that the metal powder in the receiving barrel 7 falls into the molding cavity 3, preparing for the subsequent metal powder pressing and molding. Then, under the action of the driving member, the receiving barrel 7 is moved again to the bottom of the output end of the feeding mechanism 6 to receive the material. At the same time, the first electric push rod 4 is started to drive the extrusion plate 5 to slide into the molding cavity 3 to achieve the effect of extruding the metal powder. Then, after the first electric push rod 4 is retracted and reset, the ejection mechanism ejects the molded part.

[0040] Further, the limiting member includes a clamping rod 30 movably penetrating the first mounting block 20 and a pressure block 28 disposed at the upper end of the clamping rod 30. The upper end of the first mounting block 20 is provided with a sliding cavity for the pressure block 28 to slide. The pressure block 28 is hemispherical and the lower end is connected to the bottom surface of the sliding cavity through a compression spring 29. The lower end surface of the second mounting block 21 is provided with a groove that matches the pressure block 28. The inner bottom surface of the mounting groove 37 is provided with a clamping groove 31 that matches the clamping rod 30. The driving member includes a sliding member disposed on the mounting block 21. The movable plate 35 inside the mounting groove 37 and the gear 27 fixedly arranged on the upper end of the rotating shaft, the second electric push rod 26 for driving the movable plate 35 to move is fixedly arranged inside the mounting groove 37, and a rack 22 matching with the gear 27 is arranged on one side of the movable plate 35. When in use, since the clamping rod 30 is not aligned with the clamping groove 31, the pressure block 28 is in the groove. When the second electric push rod 26 drives the receiving barrel 7 to move below the feeding mechanism 6, since the second mounting block 21 cannot deflect, it first drives the first The mounting block 20 and the second mounting block 21 slide synchronously. When the first mounting block 20 slides and abuts against one end of the mounting groove 37, the clamping rod 30 is aligned with the clamping groove 31. Since the first mounting block 20 cannot continue to move, the second electric push rod 26 continues to extend. Under the action of the gear 27 and the rack 22, a force is given to the second mounting block 21 to rotate, and then the second mounting block 21 rotates to squeeze the pressure block 28, so that the lower end of the clamping rod 30 is clamped into the clamping groove 31. 6 is extended, so that the scraper ring 9 is fully opened, the feeding mechanism 6 adds metal powder to the receiving barrel 7, and then the second electric push rod 26 contracts. In this process, the scraper ring 9 is first deflected and reset. During the deflection and reset process of the scraper ring 9, the residual metal powder on the filter plate 33 is scraped away to prepare for subsequent filtration. When the scraper ring 9 is closed, the scraper ring 9 is located directly above the receiving barrel 7 to play a protective role. Then the second electric push rod 26 further contracts, driving the receiving barrel 7 to move toward the molding cavity 3.

[0041] Furthermore, a discharge pipe 10 cooperating with the output end of the feeding mechanism 6 is penetrated through the top surface of the support frame 2, a telescopic hose 11 is provided at the lower end of the discharge pipe 10, a connecting pipe 12 is provided at the lower end of the telescopic hose 11, two ears 17 are symmetrically provided on the outer side of the connecting pipe 12, two vertical guide rods 13 slidably cooperating with the ears 17 are fixedly provided at the lower end of the support frame 2, a transmission member cooperating with the scraping ring 9 for driving the connecting pipe 12 to rise and fall is provided on one side of the fixed plate 8, when in use, the connecting pipe 12 is pressed against the upper end surface of the filter plate 33, effectively preventing the feeding mechanism 6 from adding metal powder into the receiving barrel 7, causing the metal powder to fly.

[0042] Furthermore, the transmission member includes a rotating block 16 rotatably arranged on one side of the fixed plate 8 and squeezed by the scraper ring 9 to deflect upward, and a mounting plate fixedly arranged at the lower end of the support frame 2. A torsion spring is provided at the rotation connection between the rotating block 16 and the fixed plate 8, and a pull rope 15 is fixedly provided at the upper end of one of the support ears 17, and the other end of the pull rope 15 is fixedly connected to the upper end of the rotating block 16. A guide wheel 14 matching the pull rope 15 is provided on one side of the mounting plate. When in use, when the second electric push rod 26 drives the scraper ring 9 to open, the second electric push rod 26 is further extended to drive the scraper ring 9 to further deflect and open. At this time, the scraper ring 9 will squeeze the rotating block 16, so that the rotating block 16 deflects upward, and the rotating block 16 deflects upward to release the pull rope 15, and then the connecting tube 12 moves downward under the action of gravity. When the scraper ring 9 is closed, the rotating block 16 rotates and resets under the action of the torsion spring, and then pulls the pull rope 15, so that the connecting tube 12 moves upward, preparing for the deflection and reset of the scraper ring 9, and will not block the rotation of the scraper ring 9.

[0043] Furthermore, a counterweight ring 18 is provided at the lower end of the outer side of the connecting tube 12, and an electromagnet 32 ​​is embedded in the lower end surface of the counterweight ring 18. A touch pressure switch 19 is provided on one side of the counterweight ring 18, and the touch pressure switch 19 is electrically connected to the electromagnet 32. When the counterweight ring 18 moves downward, the touch pressure switch 19 will contact the filter plate 33, so that the touch pressure switch 19 is squeezed open, and then the electromagnet 32 ​​is energized and adsorbed on the filter plate 33, thereby ensuring the stability of the contact between the connecting tube 12 and the filter plate 33.

[0044] Furthermore, a vibration motor 34 is provided at the lower end of the filter plate 33, and the vibration motor 34 is electrically connected to the touch pressure switch 19. When the touch pressure switch 19 is turned on, the vibration motor 34 is started, and the vibration effect generated helps the filter plate 33 to filter.

[0045] Furthermore, a transverse guide rod 25 is provided inside the mounting groove 37 for sliding cooperation with the first mounting block 20 and the movable plate 35. A baffle 23 is provided on the side of the first mounting block 20 close to the second electric push rod 26 for limiting the rotation of the second mounting block 21, thereby ensuring the stability of the first mounting block 20 and the movable plate 35 during the sliding process. Under the blocking action of the baffle 23, when the scraping ring 9 is closed, one side of the second mounting block 21 abuts against the baffle 23. At this time, the pressure block 28 is aligned with the groove. Under the reset action of the compression spring 29, the pressure block 28 is snapped into the groove, so that the clamping rod 30 is disengaged from the clamping groove 31, thereby preparing for the subsequent sliding of the first mounting block 20.

[0046] Furthermore, the scraping ring 9 has the same inner and outer diameters as the receiving barrel 7, and a collecting sleeve 24 is fixedly provided on the outer side of the receiving barrel 7, so that the metal powder scraped off by the scraping ring 9 falls and is collected in the collecting sleeve 24. When in use, the staff can fill the collecting sleeve 24 with liquid according to the usage situation, so that the metal powder falls into the liquid, effectively avoiding the metal powder collected in the collecting sleeve 24 from flying under the vibration of the vibration motor 34.
