Description

Technical Field

[0001] The invention relates to the technical field of waste material recovery, in particular to a waste material recovery device for powder metallurgy. Background Art

[0002] Powder metallurgy is a metalworking method that involves pressing metal powder into the desired shape and then combining the powder particles into a solid part through high-temperature sintering or other treatment methods. This method is often used to manufacture parts with complex shapes, high strength and wear resistance.

[0003] Powder metallurgy technology is also often used to produce parts with special performance requirements, such as parts with good electrical conductivity or magnetism, and parts that work in high temperature or corrosive environments. Its advantages include reducing material waste, improving production efficiency, and being able to manufacture parts with complex shapes without additional processing.

[0004] At present, after the metal powder is pressed into the desired shape, the metal block will be sintered. During the sintering process, some metal or alloy powders may not be completely sintered into dense parts, and some materials may still be in powder form or not fully combined, forming incompletely sintered powder residues. Therefore, the sintered metal block will be polished. If the remaining material after polishing is not recovered, it will cause unnecessary waste of metal powder. If it is recycled manually, the powder needs to be cleaned, and the powder may be inhaled during the process, which is not good for health. Therefore, it does not meet the existing needs. We have proposed a residual material recovery device for powder metallurgy. Summary of the invention

[0016] The present invention has the following beneficial effects:

[0017] 1. The residual material recovery device for powder metallurgy moves the metal block to the inside of the equipment body by setting a conveying roller, and grinds the metal block by using a grinding device and a flushing gun to achieve deburring and polishing of the metal block. At the same time, the residual powder after grinding can be brought into the recovery box along with the water flow, thereby reducing the residual powder floating in the air, keeping the working environment clean as much as possible, and reducing cleaning time and cost; in the process of the residual powder water flow entering the recovery box, the water flow mixed with the residual powder is filtered by the filter plate to separate the residual powder and the water flow, so that the water flow is collected in the water storage chamber, and the residual powder will fall on the surface of the filter plate for subsequent recycling, thereby facilitating the collection of the residual powder;

[0018] Moreover, by setting the filter plate as the first plate and the second plate, and by rotating the motor in coordination with the second rack and the second rack, the residual powder falling on the surface of the first plate and the second plate can be moved along a specific path to the upper side of the slot of the collecting tank, and then the scraper is pushed to move by the pushing cylinder. The scraper will drop the residual material on the surface of the filter plate into the collecting tank, which can make the water flow mixed with the residual powder more efficient during the filtration process, and at the same time improve the efficiency of separating and collecting the residual powder, realize the automation of residual material collection, and reduce labor costs.

[0019] 2. In the process of scraping off the residual material on the surface of the filter plate, the tooth segment of the powder metallurgy residual material recovery device meshes with the flip gear to control the inclination angle of the scraper, so that the scraper can scrape off the residual material, thereby improving the scraping effect; a driving gear is installed on the output shaft surface of the rotating motor, and two adjustment racks are meshed with the driving gear. When the driving gear rotates, the adjustment rack moves up and down, so that the adjustment plate moves up and down, so that the scraper adaptively adjusts the horizontal height to contact the first plate and the second plate. Therefore, when the first plate and the second plate move back and forth, the scraper can scrape off the residual powder on both sides of the filter plate, thereby improving the collection of residual powder.

[0020] 3. In the powder metallurgy waste material recovery device, when the flip gear is meshed with the tooth segment, the scraper is lifted up and the upper surface of the scraper contacts the cleaning plate. When the scraper retreats along the track groove, the cleaning plate can scrape off the waste material adhering to the scraper surface, causing the waste material to fall into the collecting groove, thereby improving the waste material collection efficiency. A volute spring is installed between the flip gear and the sliding column. During the meshing of the flip gear and the tooth segment, the volute spring is in a collecting state. After the flip gear loses meshing with the tooth segment, the volute spring is released, thereby achieving the scraper shaking effect, causing the waste material adhering to the scraper surface to shake and fall, thereby further improving the waste material collection.

DETAILED DESCRIPTION

[0030] 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.

[0031] Embodiment 1: This embodiment is intended to promote the solution of the problem that after the metal powder is pressed into the desired shape, the metal block will be sintered. During the sintering process, some metal or alloy powders may not be completely sintered into dense parts, and some materials may still be in powder form or not fully combined, forming incompletely sintered powder residues. Therefore, the sintered metal block will be polished. If the remaining materials after polishing are not recycled, it will cause unnecessary waste of metal powder. If the powder is recycled manually, it is necessary to clean the powder, and the powder may be inhaled during the process, which is not good for health. Please refer to Figure 1-Figure 8 , a powder metallurgy waste material recovery device, see Figure 1 , Figure 2 , including an equipment body 110, a conveying roller 111 for conveying powder blocks, and a grinding device 112 for grinding the powder blocks, characterized in that: a flushing gun 113 for flushing the powder is installed on the side of the grinding device 112, a recovery box 120 is installed on the bottom side of the equipment body 110, a water inlet channel 121 is opened on the surface of the recovery box 120, and the water inlet channel 121 is located on the bottom side of the equipment body 110, a filter plate 130 for sieving and recovering the powder is installed inside the recovery box 120, and a rotating electric The machine 140 has a rotating gear 141 installed on the output shaft surface of the rotating motor 140 for adjusting the position of the filter plate 130. A water storage chamber 150 is provided inside the recovery box 120, and the water storage chamber 150 is located on the bottom side of the filter plate 130. A collecting trough 160 for collecting residual materials is provided inside the recovery box 120, and the collecting trough 160 is located on both sides of the water storage chamber 150. A hair dryer 230 for drying the residual powder is installed inside the collecting trough 160. A water pump 114 is installed on the side of the water storage chamber 150, and the connecting pipe of the water pump 114 is connected to the flushing gun 113.

[0032] See Figure 1 , Figure 2 In the specific implementation, the sintered metal block is placed on the surface of the conveying roller 111, and the metal block is transported to the inside of the equipment body 110 by the conveying roller 111. While the metal block is polished by the grinding device 112, the surface of the metal block is polished by the flushing gun 113, and the residual material after grinding is washed off, so that the residual material is recovered inside the water flow recovery box 120. When the water flow passes through the filter plate 130, the residual powder and the water flow are separated, and the water flow passes through the filter plate 130 to reach the inside of the water storage chamber 150, and at the same time, the residual powder will fall on the surface of the filter plate 130.

[0033] See Figure 3 , Figure 4The filter plate 130 includes a first plate 131 and a second plate 132. Two filter plates 130 are provided to increase the number of filtration times and improve the separation effect of water flow and residual powder. A first rack 133 is installed on the bottom side of the first plate 131, and a second rack 134 is installed on the upper side of the second plate 132. The first rack 133 and the second rack 134 are simultaneously engaged with the rotating gear 141. A lifting rod 135 is installed between the second rack 134 and the second plate 132. The setting of the lifting rod 135 allows a distance to exist between the second rack 134 and the second plate 132. The first plate 131 and the second plate 132 are movably interlaced on the bottom side of the water inlet channel 121.

[0034] See Figure 3 , Figure 4 , Figure 8 A scraper 170 for scraping off powder on the surface of the filter plate 130 is installed inside the recovery box 120, and two scrapers 170 are provided. The two scrapers 170 are movably arranged inside the recovery box 120, and an adjustment plate 171 is slidably installed on the inner wall of the recovery box 120, and a pushing cylinder 172 for pushing the scraper 170 is installed on the surface of the adjustment plate 171.

[0035] See Figure 3 , Figure 4 , Figure 8 In a specific implementation, the first plate 131 and the second plate 132 are driven to move by the cooperation of the rotating motor 140 and the second rack 134, so that the residual powder falling on the surface of the first plate 131 and the second plate 132 can be close to the notch of the collecting tank 160. After the filter plate 130 and the notch of the collecting tank 160 are close, the scraper 170 is pushed to move by the pushing cylinder 172, so that the scraper 170 hangs the residual material on the surface of the filter plate 130 into the inside of the collecting tank 160 for collection.

[0036] Figure 2 , Figure 3 The bottom surface of the collecting tank 160 is set as a filter net 231, and a pushing plate 232 for pushing the residual material is installed inside the collecting tank 160, and a movable cylinder 233 for controlling the pushing plate 232 is installed inside the collecting tank 160. A movable seat 234 is installed between the movable cylinder 233 and the pushing plate 232. A sliding groove 235 is opened on the surface of the pushing plate 232. The movable seat 234 includes a sliding block 240 inside the sliding groove 235 in a sliding fit, and a connecting block 241 installed on the side plate of the sliding block 240, and the connecting block 241 is hinged to the movable end of the movable cylinder 233.

[0037] In specific implementation, when the residual material falls into the collecting tank 160, the residual material is blown dry by the hair dryer 230; after the residual material is blown dry, the movable cylinder 233 cooperates with the movable seat 234 and the pushing plate 232 to push the residual material out from the collecting tank 160.

[0038] In this embodiment: by setting the conveying roller 111, the metal block is moved to the inside of the equipment body 110, and the metal block is polished by using the polishing device 112 and the flushing gun 113, so as to achieve deburring and polishing of the metal block, and the residual powder after polishing can also enter the inside of the recovery box 120 with the water flow, thereby reducing the residual powder floating in the air, keeping the working environment clean as much as possible, and reducing the cleaning time and cost; in the process of the residual powder water flow entering the recovery box 120, the water flow mixed with the residual powder is filtered by the filter plate 130 to separate the residual powder and the water flow, so that the water flow is collected in the water storage chamber 150, and is subsequently recycled, and the residual powder will fall on the surface of the filter plate 130, thereby facilitating the collection of the residual powder;

[0039] Moreover, by setting the filter plate 130 as the first plate 131 and the second plate 132, and by rotating the motor 140 and cooperating with the second rack 134 and the second rack 134, the residual powder falling on the surface of the first plate 131 and the second plate 132 can be moved along a specific path to the upper side of the slot of the collecting tank 160, and then the scraper 170 is pushed to move by pushing the cylinder 172. The scraper 170 will drop the residual material on the surface of the filter plate 130 into the inside of the collecting tank 160, which can make the water flow mixed with the residual powder more efficient during the filtration process, and at the same time improve the efficiency of separating and collecting the residual powder, realize the automation of residual material collection, and reduce labor costs.

[0040] Embodiment 2: This embodiment is intended to promote the solution of the problem that the residual material on both sides of the filter plate can be scraped off during the reciprocating motion of the first plate 131 and the second plate 132. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 8 ,See Figure 3 , Figure 4 and Figure 8 A scraper 170 for scraping off powder on the surface of the filter plate 130 is installed inside the recovery box 120, and two scrapers 170 are provided. The two scrapers 170 are movably arranged inside the recovery box 120, and an adjustment plate 171 is slidably installed on the inner wall of the recovery box 120, and a pushing cylinder 172 for pushing the scraper 170 is installed on the surface of the adjustment plate 171.

[0041] See Figure 3 , Figure 4 and Figure 8 In a specific implementation, by setting the two scrapers 170, when the first plate 131 and the second plate 132 are moved alternately to the upper sides of the two collecting troughs 160, the residual materials on one side of the first plate 131 and the second plate 132 can be dropped respectively.

[0042] See Figure 3 , Figure 4 and Figure 8A track groove 173 for controlling the position of the scraper 170 is provided on the surface of the adjustment plate 171. A sliding seat 180 for sliding with the track groove 173 is installed on the side of the scraper 170. The sliding seat 180 includes a sliding column 181 that slides with the track groove 173, and a flip gear 182 installed on the upper side of the sliding column 181. A tooth segment 184 is provided inside the track groove 173, and the tooth segment 184 is meshed with the flip gear 182.

[0043] See Figure 3 , Figure 4 and Figure 8 In the specific implementation, before the residual material on the surface of the filter plate 130 is dropped, the sliding seat 180 is located above the track groove 173 by means of the extension and contraction of the movable end of the movable cylinder 233; in the process of dropping the residual material on the surface of the filter plate 130, while the sliding seat 180 is located at the bottom side of the track groove 173, the movable end of the movable cylinder 233 is extended, so that the scraper 170 pushes the residual powder on the surface of the filter plate 130, causing the residual powder to fall into the collecting tank 160.

[0044] See Figure 3 , Figure 4 and Figure 8 An adjustment groove 190 is provided on the side plate of the scraper 170, and an articulated seat 191 is installed between the pushing cylinder 172 and the scraper 170. The articulated seat 191 includes an articulated block 192 hinged at the movable end of the pushing cylinder 172, and an adjustment block 193 installed on the side of the articulated block 192. The adjustment block 193 slides with the adjustment groove 190. Through the cooperation between the adjustment groove 190 and the articulated seat 191, when the movable end of the movable cylinder is extended or retracted, the sliding seat can automatically adjust the height, thereby sliding with the track groove.

[0045] See Figure 3 , Figure 4 and Figure 8 When the flip gear 182 is meshed with the tooth segment 184, the scraper 170 is flipped according to the rotation of the flip gear 182, so that the scraper 170 is tilted. A driving gear 210 is installed on the output shaft surface of the rotating motor 140, and an adjusting rack 211 is installed on the side of the adjusting plate 171. The adjusting rack 211 is meshed with the driven gear 210. When the driving gear 210 rotates, the two adjusting racks 211 move up and down respectively; when the output shaft of the rotating motor 140 rotates, the first plate 131 and the second plate 132 are displaced, so that there is a gap between the scraper 170 and the first plate 131 and the second plate 132. By meshing the adjusting rack 211 with the driven gear 210, when the first plate 131 and the second plate 132 are displaced, the scraper 170 can adaptively adjust the horizontal height to contact the first plate 131 and the second plate 132, so that the residual material on the surface of the filter plate 130 can be scraped off.

[0046] See Figure 3 , Figure 4 and Figure 8 In a specific implementation, when the sliding seat 180 slides to the tooth segment 184, the flip gear 182 is meshed with the tooth segment 184, so that the flip gear 182 rotates, driving the scraper 170 to tilt, so that the bottom side of the scraper 170 is tilted to the side of the filter plate 130, and at the same time, the effect of shoveling the residual material is achieved, thereby improving the scraping effect of the residual material; a driving gear 210 is installed on the output shaft surface of the rotating motor 140, and two adjustment racks 211 are meshed with the driving gear 210. When the driving gear 210 rotates, the adjustment rack 211 moves up and down, so that the adjustment plate 171 moves up and down, so that when the first plate 131 and the second plate 132 move back and forth, the scraper 170 can scrape off the residual powder on both sides of the filter plate 130.

[0047] In this embodiment: in the process of scraping off the residual material on the surface of the filter plate 130, the tooth segment 184 is meshed with the flip gear 182, so as to control the inclination angle of the scraper 170, so that the scraper 170 can scrape up the residual material, thereby improving the scraping effect; a driving gear 210 is installed on the output shaft surface of the rotating motor 140, and two adjustment racks 211 are meshed with the driving gear 210. When the driving gear 210 rotates, the adjustment rack 211 moves up and down, so that the adjustment plate 171 moves up and down, so that the scraper 170 adaptively adjusts the horizontal height to contact the first plate 131 and the second plate 132. Therefore, when the first plate 131 and the second plate 132 move back and forth, the scraper 170 can scrape off the residual powder on both sides of the filter plate 130, thereby improving the collection of residual powder.

[0048] Embodiment 3: This embodiment aims to solve the problem that when the scraper sweeps away the residual material, a small amount of residual material will adhere to the scraper surface, resulting in a decrease in the residual material collection efficiency. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 8 ,See Figure 6 , Figure 7 , a volute spring 183 is provided between the flip gear 182 and the sliding column 181, and the flip gear 182 is connected to the scraper 170. A support block 250 is installed on the surface of the adjustment plate 171, and a cleaning plate 251 for cleaning the scraper 170 is installed on the bottom side of the connecting block 241, and the cleaning plate 251 is in active contact with the scraper 170. A support rod 252 is installed between the cleaning plate 251 and the support block 250, and a support spring 253 is provided on the surface of the support rod 252, and the support rod 252 is in active contact with the inside of the cleaning plate 251.

[0049] In this embodiment: when the flip gear 182 is meshed with the tooth segment 184, the scraper 170 is lifted up and the upper surface of the scraper 170 contacts the cleaning plate 251. When the scraper 170 retreats along the track groove 173, the cleaning plate 251 can scrape off the residual material adhered to the surface of the scraper 170, so that the residual material falls into the collecting groove 160, thereby improving the efficiency of collecting the residual material. By installing a volute spring 183 between the flip gear 182 and the sliding column 181, the volute spring 183 is in a collecting state during the meshing of the flip gear 182 and the tooth segment 184. After the flip gear 182 loses meshing with the tooth segment 184, the volute spring 183 is released, thereby achieving the effect of shaking the scraper 170, causing the residual material adhered to the surface of the scraper 170 to shake and fall, thereby further improving the collection of the residual material.
