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 DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0032] Reference Figure 1 A dust removal device for a metal powder processing workshop comprises a dust collecting mechanism 1 and a dust removing mechanism 3. The dust collecting mechanism 1 comprises a processing table 11. The processing table 11 is composed of two left-right symmetrical dust shields and a processing support plate fixed together at the middle of the two dust shields. A discharge box 2 is connected to the processing support plate for forward and backward sliding. The discharge box 2 is provided with a dust removing mechanism 3. The dust collecting mechanism 1 and the dust removing mechanism 3 are jointly provided with an anti-pollution component 4. A U-shaped collecting box 6 is fixedly connected to the bottom wall of the processing support plate. A wet processing mechanism 5 is jointly provided on the dust collecting mechanism 1 and the U-shaped collecting box 6.

[0033] Reference Figure 1 to Figure 2 A rear inclined partition 12 is fixedly connected to the rear of the processing pallet, a front inclined partition 13 is fixedly connected to the front of the processing pallet, and a pushing piece 14 is fixedly connected front and back symmetrically between the two dust guards. The pushing piece 14 consists of an inverted T-shaped piece fixedly connected to the two dust guards and a wedge block 1 fixed to the top wall of the vertical section of the inverted T-shaped piece, and 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 pallet through the discharge box 2, and the powder in the mold is compressed into a green body of the desired shape by a hydraulic device (not shown in the figure) installed on the lower side of the processing pallet.

[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 Figure 3 to Figure 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 Fig.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 on the rear 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 while tilting backward at the fence 12 to scrape the scattered metal powder on the middle part of the top wall of the processing pallet; the scraper 33 on the front 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 front side from being driven to the rear side and causing pollution during the backward movement.

[0045] During the forward and backward movement of the discharge box 2, the ferromagnetic part of the metal powder scattered on the middle of the top wall of the processing support plate is magnetically attracted by the magnetic block 342 and adsorbed on the bottom wall of the barrier 343. The magnetic block 342 helps to reduce the scraping pressure of the scraper 33, and the magnetic component 34 cooperates with the scraper 33 to remove the metal powder scattered on the middle of the top wall of the processing support plate; when the discharge box 2 drives the magnetic component 34 to move close to the rear inclined partition 12 or the front inclined partition 13, the inverted U-shaped part 344 gradually approaches the pushing part 14, and the top wall of the wedge block gradually clings to the bottom wall of the inverted U-shaped part 344 and pushes the inverted U-shaped part 344 and the support rod 341 to move upward, thereby driving the magnetic block 342 to move up and away from the barrier 343. The ferromagnetic metal powder adsorbed on the bottom wall of the barrier 343 is gradually attracted by the magnetism until it is no longer attracted, and then it will fall from above the rear inclined partition 12 or the front inclined partition 13 into the interior of the U-shaped collecting 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 2 to gradually approach the wedge block 42, and the inclined outer wall of the L-shaped follower 41 is close to the inclined outer wall of the wedge block 42 and pushes the wedge block 42 and the blocking partition 43 to slide to the right. The blocking partition 43 changes from an interlaced state with the corresponding rear inclined partition 12 or front inclined partition 13 to an overlapping state, so that the powder scraped by the scraper 33 and collected by the magnetic suction component 34 can smoothly enter the interior of the U-shaped collecting box 6.

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

[0048] Reference Figure 1 , Figure 8 and Fig. 9The wet processing mechanism 5 includes a driving assembly 51 which is jointly arranged on the support frame 31 and the U-shaped collecting box 6. The driving assembly 51 includes two L-shaped plates 511 which are symmetrically distributed on the 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-to-back moving rod 512 which faces forward and backward. The bottom wall of the front-to-back moving rod 512 is fixed with a front-to-back symmetrical wedge block three; the inner top wall of the U-shaped collecting box 6 is connected with a left-to-right symmetrically distributed lower pressure plate 514 through a spring three (not shown in the figure), and the top walls of the two lower pressure plates 514 are fixed with a return frame 513 through a plurality of connecting rods which slide through the top wall of the U-shaped collecting box 6. The return frame 513 is arranged above the U-shaped collecting box 6, and the top wall of the return frame 513 is fixedly connected with a plurality of wedge blocks four corresponding to the wedge blocks three.

[0049] Reference Figure 1 , Figure 8 and Fig. 9 A water tank 53 is symmetrically installed on the top wall of the U-shaped collecting box 6. A point spray assembly 52 is commonly provided on the U-shaped collecting box 6 and the water tank 53. The point spray assembly 52 includes a downpipe 523. A downpipe 523 fixedly penetrating the top wall of the U-shaped collecting box 6 is installed on the side wall of the water tank 53. The water tank 53 is connected to the U-shaped water storage box 521 through the downpipe 523. A press nozzle 522 is installed on the top wall of the U-shaped water storage box 521.

[0050] The pressing nozzle 522 adopts the existing pressing water spraying technology, and its specific structure is not described here. The water stored in the water tank 53 enters the U-shaped water storage box 521 through a water pump (not shown in the figure) and a downpipe 523. During the forward and backward movement of the discharge box 2, the support frame 31 drives the L-shaped plate 511, the forward and backward moving rod 512 and the wedge block three to move horizontally forward and backward. During the movement of the forward and backward moving rod 512 and the wedge block three, the wedge block four below is pushed to move downward, and the wedge block four drives the U-shaped frame 513 and the lower pressure plate 514 to move downward intermittently, and the lower pressure plate 514 presses the corresponding pressing nozzle 522 below, and intermittently presses the pressing nozzle 522 to spray water, so as to wet the dust inside the U-shaped collecting box 6, and reduce the dust inside the U-shaped collecting box 6 for unified recovery.

[0051] The specific operating steps of the dust removal device of the metal powder processing workshop are as follows: the discharge box 2 drives the support frame 31 to move back and forth on the top wall of the processing pallet of the processing table 11, and multiple dust heads 324 vacuum the metal powder scattered on the left and right top walls of the processing pallet. At the same time, the dust heads 324 are driven by the roller 321 to deflect back and forth in the process of moving back and forth with the discharge box 2, so as to expand the dust collection range; the scraper 33 moves back and forth with the support frame 31, and scrapes the metal powder scattered on the middle part of the top wall of the processing pallet toward the corresponding front inclined partition 13 and rear inclined partition 12; at the same time, the magnetic suction component 34 cooperates with the scraper 33, and the ferromagnetic part of the powder is magnetically attracted by the magnetic suction block 342 and adsorbed on the bottom wall of the barrier 343.

[0052] The overlapping state of the blocking fence 43 and the corresponding rear inclined fence 12 or front inclined fence 13 can prevent dust from flying inside the U-shaped collecting box 6; the blocking fence 43 changes from an interlaced state with the corresponding rear inclined fence 12 or front inclined fence 13 to an overlapping state, so that the powder scraped by the scraper 33 and collected by the magnetic suction component 34 can normally enter the interior of the U-shaped collecting box 6, and the dust reduction treatment is performed on the interior of the U-shaped collecting box 6 by intermittently pressing the pressing nozzle 522 to spray water.
