Description

Technical Field

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

[0002] Metal powder processing is a manufacturing process that uses metal powder as raw material to produce parts or products of various shapes and sizes. Common processing technologies include: powder metallurgy, metal injection molding, etc. Powder metallurgy refers to the method of manufacturing parts by pressing and sintering metal powder. First, the metal powder is loaded into a mold and pressed into a green body of the desired shape under high pressure. The green body is sintered to form a continuous and dense structure between the particles.

[0003] At present, in the process of powder metallurgy, dust pollution is caused in the processing workshop due to the overflow or scattering of some powder when the mold is filled during the pressing stage. Improper operation during the demoulding stage will also cause some loose powder to fall off and become dust. The existing method of dust removal at the source of dust generation is usually to push the raw embryo to be unloaded through the unloading push plate on the operating table, and at the same time, the powder scattered on the table is scraped off. The raw embryo is moved to the unloading place, and the scraped powder passes through the mesh plate when passing through the unloading place and falls and is collected. However, the method of scraping with the push plate is relatively simple, and the scraping effect needs to be improved. In addition, when the powder is scraped off when the raw embryo is pushed to be unloaded, there is a lag in the dust removal time, and the dust scattering cannot be suppressed in time. Furthermore, the scraped powder passes through the mesh plate at the unloading place and falls and is collected, and part of the collected powder will fly up again when new powder falls, causing secondary pollution to the working environment.

[0004] Therefore, in order to improve the dust removal effect and timely suppress the dispersion of dust, the present invention provides a dust removal device for a metal powder processing workshop. Summary of the invention

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 , a dust removal device for a metal powder processing workshop, including a dust collection mechanism 1 and a dust removal mechanism 3. The dust collection mechanism 1 includes a processing table 11, which is composed of two symmetrically arranged dust-proof plates on the left and right and a processing support plate fixed in the middle of the two dust-proof plates. An outlet box 2 is slidably connected to the front and rear of the processing support plate. A dust removal mechanism 3 is arranged on the outlet box 2. An anti-pollution assembly 4 is jointly arranged on the dust collection mechanism 1 and the dust removal mechanism 3. The bottom wall of the processing support plate is fixedly connected with a U-shaped collection box 6. A wet treatment mechanism 5 is jointly arranged on the dust collection mechanism 1 and the U-shaped collection box 6.

[0033] Refer to Figures 1 to 2 , a rear inclined partition 12 is fixedly connected to the rear part of the processing support plate, a front inclined partition 13 is fixedly connected to the front part of the processing support plate, and a pushing member 14 is symmetrically fixedly connected to the front and rear between the two dust-proof plates. The pushing member 14 is composed of an inverted T-shaped member fixedly connected to the two dust-proof plates and a wedge block 1 fixed to the top wall of the vertical section of the inverted T-shaped member. The top wall of the wedge block 1 is inclined.

[0034] First, the prepared metal powder is moved to the mold cavity installed in the middle of the processing support plate through the outlet box 2, and the powder in the mold is compressed into a green body of the required shape by hydraulic equipment (not shown in the figure) installed on the upper and lower sides of the processing support plate.

[0035] The discharge box 2 reciprocates back and forth on the top wall of the processing pallet. When the discharge box 2 moves, it first pushes the formed green embryo forward to the front inclined fence 13 for unloading. When returning to reset, the metal powder is discharged in the middle of the processing pallet to facilitate the production of the next green embryo, so as to facilitate continuous production.

[0036] The discharge box 2 drives the dust removal mechanism 3 to remove the powder scattered on the processing pallet in a variety of ways. The powder falls through the rear inclined fence 12 and the front inclined fence 13 to the inside of the U-shaped collecting box 6 for collection. At the same time, the anti-pollution component 4 cooperates with the pushing piece 14 to prevent the powder from passing through the rear inclined fence 12 and the front inclined fence 13 and flying to cause secondary pollution. The discharge box 2 drives the wet treatment mechanism 5 to wet the powder collected in the U-shaped collecting box 6 to reduce the generation of dust by wetting the metal powder.

[0037] Reference Figures 1 to 3 The dust removal mechanism 3 includes a support frame 31 detachably mounted on the discharge box 2, a dust suction component 32 arranged on the support frame 31 for sucking and recovering scattered powder, a scraper 33 for scraping and collecting the powder, and a magnetic suction component 34 for magnetically absorbing and collecting the powder; the support frame 31 is a circular structure composed of two inverted L-shaped driving plates symmetrically distributed on the left and right and two connecting plates symmetrically distributed front and back, which are fixedly connected to each other; the two inverted L-shaped driving plates are connected with a scraper 33 symmetrically distributed front and back through an electric slider to slide up and down together.

[0038] Reference Figures 3 to 4 The dust collecting assembly 32 includes a deflection seat 323 rotatably arranged on the support frame 31, a dust collecting head 324 is installed on the deflection seat 323, a plurality of rollers 321 distributed front and back are rotatably connected to the bottom wall of the vertical section of the inverted L-shaped driving plate, a rotating block 322 is coaxially fixedly connected to the side away from each other of the left and right corresponding rollers 321, a convex block 1 is fixedly connected to the side wall of the rotating block 322, a torsion spring rod is rotatably connected to the bottom wall of the horizontal section of the inverted L-shaped driving plate, a deflection seat 323 and a deflection block 325 are coaxially fixedly connected to the outer wall of the torsion spring rod, a convex block 2 is fixedly connected to the side wall of the deflection block 325, and the deflection block 325 corresponds to the rotating block 322 up and down.

[0039] Reference Figure 3 and Figure 5The magnetic suction component 34 includes a support rod 341 arranged on the support frame 31, and a magnetic suction block 342 is symmetrically installed on the bottom wall of the support rod 341 through a hanging ring. The top walls of the two inverted L-shaped driving plates are connected to the front and rear symmetrical support rods 341 by sliding up and down through a spring 1 (not shown in the figure), and the side walls of the two inverted L-shaped driving plates close to each other are fixedly connected to the upper and lower corresponding blocking members 343 of the support rod 341 through a connecting plate; the blocking member 343 is composed of two cylinders sleeved on the outside of the magnetic suction block 342, and the cylinder of the blocking member 343 is made of pv material. The top wall of the support rod 341 is fixedly connected to an inverted U-shaped member 344 corresponding to the pushing member 14, and the bottom wall of the horizontal section of the inverted U-shaped member 344 is in an inclined shape that matches the top wall of the wedge block 1.

[0040] Reference Figure 6 , Figure 7 and Figure 10 The anti-pollution component 4 includes an L-shaped follower 41. The top wall of the inverted L-shaped driving plate on the right side is fixedly connected to the front-to-back symmetrical L-shaped followers 41. The two L-shaped followers 41 are fixedly connected to wedge blocks 2 on the sides away from each other, and the side of wedge block 2 away from the L-shaped follower 41 is inclined; the bottom walls of the rear inclined fence 12 and the front inclined fence 13 are slidably connected to the blocking fence 43 left and right through spring 2 (not shown in the figure), and the top wall of the blocking fence 43 is fixedly connected to a wedge block piece 42 corresponding to the wedge block 2, and the side of the wedge block piece 42 close to the L-shaped follower 41 is inclined to match the side wall of the wedge block 2.

[0041] The vacuum head 324 is connected to an external vacuum device through a pipe. The metal powder scattered on the left and right top walls of the processing tray of the processing table 11 is vacuumed through multiple vacuum heads 324, and the dust is directly removed at the source of generation to prevent the dust from spreading into the working environment.

[0042] When the discharge box 2 moves back and forth, it drives the support frame 31 to move synchronously. When the support frame 31 moves, the roller 321 rolls, and the roller 321 drives the rotating block 322 and the protrusion 1 to rotate. The protrusion 1 intermittently moves the protrusion 2 on the deflection block 325, and the protrusion 2 drives the deflection block 325 and the coaxially connected deflection seat 323 to deflect, and the dust suction head 324 expands the dust suction range accordingly. When the protrusion 2 is no longer in contact with the protrusion 1, the torsion spring rod adaptively rotates and resets, so that the dust suction head 324 can deflect back and forth as the discharge box 2 moves back and forth, thereby expanding the dust suction range and improving the dust suction efficiency.

[0043] When the discharge box 2 moves forward, the scraper 33 on the front side is driven by the electric slider, and its bottom wall is in contact with the top wall of the processing pallet, so that it moves and tilts forward at the fence 13 to scrape the scattered metal powder on the middle part of the top wall of the processing pallet; the scraper 33 on the rear side is driven by the electric slider, and its bottom wall is higher than the top wall of the processing pallet, so as to prevent the metal powder on the rear side from being driven to the front side and causing pollution during the forward movement.

[0044] When the discharge box 2 moves backward, the scraper 33 at the rear side is driven by the electric slider, and its bottom wall is attached to the top wall of the processing pallet, so as to scrape the metal powder scattered on the middle part of the top wall of the processing pallet while moving and tilting backward towards the rear inclined partition 12; the scraper 33 at the front side is driven by the electric slider, and its bottom wall is higher than the top wall of the processing pallet, preventing the metal powder at the front side from being driven to the rear side during the backward movement and causing pollution.

[0045] During the forward and backward movement of the discharge box 2, the ferromagnetic part of the metal powder scattered on the middle part of the top wall of the processing pallet is magnetically attracted by the magnetic attraction block 342 and adsorbed on the bottom wall of the barrier member 343. The magnetic attraction block 342 helps to reduce the scraping pressure of the scraper 33. The magnetic attraction assembly 34 and the scraper 33 cooperate to remove the metal powder scattered on the middle part of the top wall of the processing pallet; when the discharge box 2 drives the magnetic attraction assembly 34 to move close to the rear inclined partition 12 or the front inclined partition 13, the inverted U-shaped member 344 gradually approaches the pusher 14, and the top wall of the wedge block I gradually adheres to the bottom wall of the inverted U-shaped member 344 and pushes the inverted U-shaped member 344 and the support rod 341 to move upward, thereby driving the magnetic attraction block 342 to move upward and separate from the barrier member 343. After the magnetic force on the ferromagnetic metal powder adsorbed on the bottom wall of the barrier member 343 gradually becomes smaller until it is no longer attracted, it will fall from above the rear inclined partition 12 or the front inclined partition 13 into the interior of the U-shaped collection box 6.

[0046] When the discharge box 2 moves forward and backward to the rear inclined partition 12 and the front inclined partition 13, the support frame 31 drives the L-shaped follower 41 and the wedge block II to gradually approach the wedge block member 42. The inclined outer wall of the L-shaped follower 41 closely adheres to the inclined outer wall of the wedge block member 42 and pushes the wedge block member 42 and the blocking partition 43 to slide to the right. The blocking partition 43 changes from a state of intersecting with the corresponding rear inclined partition 12 or the front inclined partition 13 to a state of overlapping, so that the powder scraped by the scraper 33 and adsorbed and collected by the magnetic attraction assembly 34 can smoothly enter the interior of the U-shaped collection box 6.

[0047] When the discharge box 2 is away from the rear inclined partition 12 and the front inclined partition 13, the overlapping state of the blocking partition 43 and the corresponding rear inclined partition 12 or the front inclined partition 13 can prevent the dust in the U-shaped collection box 6 from flying, avoiding secondary pollution of the working environment.

[0048] Refer to Figure 1 、 Figure 8 and Figure 9, the wet treatment mechanism 5 includes a driving component 51 jointly arranged on the support frame 31 and the U-shaped collection box 6. The driving component 51 includes two L-shaped plates 511 symmetrically distributed left and right. The two L-shaped plates 511 are respectively fixedly installed on the top walls of the two inverted L-shaped driving plates. The bottom wall of the L-shaped plate 511 is fixedly connected with a front-back moving rod 512 facing the front and back. The bottom wall of the front-back moving rod 512 is fixed with two symmetric wedges three front and back; the inner top wall of the U-shaped collection box 6 is connected with two symmetrically distributed lower pressing plates 514 through springs three (not shown in the figure). The top walls of the two lower pressing plates 514 are fixed to the return frame 513 through a plurality of connecting rods sliding through the top wall of the U-shaped collection box 6. The return frame 513 is arranged above the U-shaped collection box 6. The top wall of the return frame 513 is fixedly connected with a plurality of wedges four corresponding to the wedges three.

[0049] Refer to Figure 1 , Figure 8 and Figure 9 , the top wall of the U-shaped collection box 6 is symmetrically installed with water tanks 53 on the left and right. A point spraying component 52 is jointly arranged on the U-shaped collection box 6 and the water tanks 53. The point spraying component 52 includes a down pipe 523. The side wall of the water tank 53 is installed with a down pipe 523 fixedly penetrating the top wall of the U-shaped collection box 6. The water tank 53 is connected to the return water storage box 521 through the down pipe 523. The top wall of the return water storage box 521 is installed with a pressing nozzle 522.

[0050] The pressing nozzle 522 adopts the existing pressing and spraying technology, and its specific structure will not be elaborated here. The water stored in the water tank 53 enters the return water storage box 521 through a water pump (not shown in the figure) and the down pipe 523. During the forward and backward movement of the discharge box 2, the support frame 31 drives the L-shaped plate 511, the front-back moving rod 512 and the wedge three to move horizontally forward and backward. During the movement of the front-back moving rod 512 and the wedge three, they push the lower wedge four to move downwards. The wedge four drives the return frame 513 and the lower pressing plate 514 to move downwards intermittently. The lower pressing plate 514 presses the corresponding pressing nozzle 522 below intermittently, and sprays water by pressing the pressing nozzle 522 intermittently to wet-treat the dust inside the U-shaped collection box 6, and it is convenient to uniformly recover the dust by dust reduction inside the U-shaped collection box 6.

[0051] The specific operation steps of the dust removal device for this metal powder processing workshop are as follows: The discharge box 2 drives the support frame 31 to reciprocate back and forth on the top wall of the processing pallet of the processing table 11. Multiple dust suction heads 324 perform dust suction on the metal powder scattered on the left and right top walls of the processing pallet. At the same time, the dust suction heads 324 are driven by the rollers 321 to reciprocally deflect during the forward and backward movement following the discharge box 2, expanding the dust suction range; The scraper 33 moves back and forth with the support frame 31, scraping the metal powder scattered in the middle of the top wall of the processing pallet towards the corresponding front inclined barrier 13 and rear inclined barrier 12; At the same time, the magnetic attraction assembly 34 cooperates with the scraper 33, and the ferromagnetic part in the powder is magnetically attracted by the magnetic attraction block 342 and adsorbed on the bottom wall of the barrier member 343.

[0052] The overlapping state of the blocking barrier 43 with the corresponding rear inclined barrier 12 or front inclined barrier 13 can prevent the dust in the U-shaped collection box 6 from flying; The blocking barrier 43 changes from the state of intersecting with the corresponding rear inclined barrier 12 or front inclined barrier 13 to the overlapping state, enabling the powder scraped by the scraper 33 and adsorbed and collected by the magnetic attraction assembly 34 to normally enter the interior of the U-shaped collection box 6. The interior of the U-shaped collection box 6 is dusted by intermittently pressing the spray nozzle 522 to spray water.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
