Description

[0003] When using an existing forming machine to punch a workpiece with a through hole and different inner diameters of the hole, the upper die of the forming machine has a corresponding protruding portion for punching the large-diameter portion of the through hole of the workpiece. However, the unloading device of the existing forming machine causes the metal powder to fall into the die hole by translation, and then the metal powder on the upper side of the die hole is scraped flat before the stamping work. After the metal powder in the die hole is scraped flat, it cannot maintain a corresponding concave shape with the protruding portion of the upper die, resulting in the accumulation thickness of the metal powder in the die hole being unable to match the required height required for stamping the workpiece shape, resulting in the concave portion of the workpiece punched out by the thicker accumulation of metal powder having greater strength and density than other portions, resulting in greatly reduced structural strength and toughness of the workpiece after extrusion molding.

[0033] The recovery component includes a powder extractor 301, a one-way recovery tube 302 and a one-way rotating plate 303; the powder extractor 301 is fixedly connected to the front side of the powder storage box 3; a plurality of one-way recovery tubes 302 are fixedly connected and connected to the upper side of the powder extractor 301; each one-way recovery tube 302 is connected to the recovery chamber 3005; two left-right symmetrical transmission ports 4003 are provided at the lower part of the push plate 4; a one-way rotating plate 303 is rotatably connected in each transmission port 4003.

[0034] Furthermore, in order to allow the metal powder in the powder storage chamber 3002 to be filled into the quantitative chamber 3003 in time, the bottom of the powder storage chamber 3002 is arranged to be inclined.

[0035] Furthermore, in order to reduce the residual metal powder on the upper side of the pressing head 5, the upper side of the pressing head 5 is configured to be in a truncated cone shape.

[0036] The present invention uses the pressing head 5 to deposit a concave pattern corresponding to the upper side of the workpiece on the upper part of the metal powder entering the die hole 1002, so that the upper side of the metal powder is at the same height as the parts of the upper side of the workpiece at different heights, thereby solving the problem that the upper side of the metal powder in the die hole 1002 can only be laid flat and cannot match the concave pattern on the upper side of the workpiece, resulting in the difference in stamping density of the stamped workpiece, which reduces the strength and toughness of the workpiece. The specific process is as follows:

[0037] When the metal powder is stamped, the metal powder is added into the powder storage chamber 3002 from the feed port 3001. After the metal powder is accumulated in the powder storage chamber 3002, it is accumulated in the quantitative chamber 3003 and is blocked by the upper side of the pressing head 5. Then, the first driving member 2 is controlled to drive the powder storage box 3 to move forward on the extrusion table 1, and then the push plate 4 is driven to move forward, so that the limit rod 4001 slides forward in the slide groove 1001. When the limit rod 4001 is blocked by the front end of the slide groove 1001, the first driving member 2 drives the powder storage box 3 to keep The push plate 4 is blocked and moves backward compared to the powder storage box 3, so that the blocking part 4002 moves toward the quantitative cavity 3003, scrapes the metal powder accumulated on the upper side of the quantitative cavity 3003, and pushes the metal powder in the powder storage cavity 3002 backward. When the lower cavity 3004 moves to the upper side of the die hole 1002 with the powder storage box 3, the blocking part 4002 blocks the upper side of the quantitative cavity 3003 and moves the pressing block 205 to the upper side of the pressing head 5. At this time, the movable block 201 is aligned with the upper side of the forming part 1003. The fourth driving member 204 is then controlled to drive the pressing block 205 to descend, and the pressing head 5 is pressed downward into the die hole 1002, so that the movable block 201 is pressed into the movable cavity 5001, and the first elastic member 202 is compressed at the same time. When the pressing head 5 descends and enters the die hole 1002, the quantitative cavity 3003 is connected with the feeding cavity 3004, and the metal powder inside the quantitative cavity 3003 enters the die hole 1002 from the gap between the feeding cavity 3004 and the outer side of the pressing head 5. When the die hole 1002 is about to be filled with metal powder, At this time, the pressing head 5 descends to the upper part of the die hole 1002, so that the upper part of the metal powder entering the die hole 1002 accumulates a concave pattern corresponding to the upper side of the workpiece, and the upper part of the metal powder is compacted to make the upper side of the metal powder consistent with the parts of the upper side of the workpiece at different heights, thereby preventing the upper side of the metal powder in the die hole 1002 from being flat and unable to match the concave pattern on the upper side of the workpiece, thereby avoiding differences in stamping density on the upper side of the stamped workpiece due to different metal powder accumulation heights, and improving the strength and toughness of the stamped workpiece.

[0038] After the metal powder is poured into the die hole 1002, the fourth driving member 204 is controlled to drive the pressing block 205 to rise. The pressing head 5 moves upward along with the pressing block 205 under the elastic force of the first elastic member 202. When the pressing head 5 moves to the upper part of the feeding cavity 3004, the edge of the pressing head 5 is clamped between the rubber clamping ring 203 and the lower side of the quantitative cavity 3003 for fixation. Then, the first driving member 2 is controlled to drive the powder storage box 3 to move backward, thereby driving the push plate 4 to move backward. The first driving member 2 drives the powder storage box 3 to move backwards. At this time, the push plate 4 moves forwards compared with the powder storage box 3, so that the blocking part 4002 moves forward on the quantitative chamber 3003, and the blockage of the quantitative chamber 3003 is released, so that the metal powder in the powder storage chamber 3002 flows into the quantitative chamber 3003, and prepares for the next unloading work.

[0039] Before the powder storage box 3 covers the mold hole 1002, the third driving member 103 is controlled to drive the movable plate 104 to rise, so that the ejection portion 10401 and the bottom of the mold hole 1002 are reserved. When the powder storage box 3 covers the upper side of the mold hole 1002, the mold hole 1002 is in a closed state, and the third driving member 103 is controlled to drive the movable plate 104 to descend, so that the ejection portion 10401 fits with the bottom of the mold hole 1002, and the mold hole 1002 is increased due to the volume increase. Negative pressure is generated. When the pressing head 5 descends, the metal powder inside the quantitative cavity 3003 enters the die hole 1002 from the gap between the feeding cavity 3004 and the outside of the pressing head 5. The negative pressure generated in the die hole 1002 sucks the quantitative cavity 3003, and the metal powder in the quantitative cavity 3003 is quickly drawn into the die hole 1002, preventing the metal powder from being blocked by the pressing head 5 and unable to quickly fall into the die hole 1002, thereby improving the feeding efficiency of the metal powder.

[0040] When the metal powder is filled into the die hole 1002, the second driving member 101 is controlled to drive the upper die 102 to descend and press it into the die hole 1002 to stamp the metal powder. When the metal powder is stamped into a workpiece, the second driving member 101 drives the upper die 102 to rise. At the same time, the third driving member 103 is controlled to drive the movable plate 104 to rise, so that the ejection part 10401 ejects the workpiece upward from the die hole 1002. The movable plate 104 compresses the gas inside the cavity 1004 during the rising process, so that the compressed gas in the cavity 1004 enters the bottom of the die hole 1002 through the through hole 1005. When the ejection part 10401 rises over the forming The lower part of the part 1003 is used, and the gas squeezed into the die hole 1002 squeezes the workpiece upward, so that the workpiece is lifted up on the upper side of the ejection part 10401, which is convenient for the workpiece to be separated from the ejection part 10401, and prevents the workpiece from adhering to the upper side of the ejection part 10401 due to extrusion, and avoids the damage of the workpiece due to tight adhesion when the workpiece is demolded, thereby improving the protection effect of the workpiece when demolding. After the workpiece is ejected from the die hole 1002, the first driving member 2 is controlled to drive the powder storage box 3 to move forward, and the workpiece is pushed to the front side of the extrusion table 1 for demolding and unloading, and at the same time, the powder storage box 3 is moved to the upper side of the die hole 1002 again to fill the metal powder, preparing for the next stamping and forming work.

[0041] When the powder storage box 3 moves forward to prepare for unloading, the push plate 4 moves backward in the powder storage box 3, so that the volume of the recovery chamber 3005 increases and negative pressure is generated. The negative pressure generated in the recovery chamber 3005 causes the powder extractor 301 to suck the upper side of the extrusion table 1, and the metal powder remaining on the upper side of the extrusion table 1 is transmitted to the recovery chamber 3005 through the one-way recovery pipe 302 through the powder extractor 301. When the powder storage box 3 moves backward to prepare for stamping, the push plate 4 moves forward in the powder storage box 3 to compress the space in the recovery chamber 3005. At this time, the one-way recovery pipe 302 is used to transfer the metal powder remaining on the upper side of the extrusion table 1 to the recovery chamber 3005. The recovery tube 302 is closed, and the compressed gas in the recovery chamber 3005 pushes open the one-way rotating plate 303, so that the gas carries the metal powder collected in the recovery chamber 3005 and transmits it to the powder storage chamber 3002 through the transmission port 4003, thereby realizing the recovery of the residual metal powder on the extrusion table 1, preventing the powder storage box 3 from wearing each other when moving on the extrusion table 1 due to the residual metal powder, thereby extending the service life of the equipment, and reducing the workload of subsequent manual recovery and cleaning of the residual metal powder, saving the production cost of the stamping workpiece.

[0042] Example 2

[0043] On the basis of Example 1, Figure 2 , Figure 4 and Figure 6As shown, it also includes a material mixing system, which includes a connecting rod 401 and a scraper 402; two connecting rods 401 that are symmetrical to each other are rotatably connected to the rear side of the push plate 4; a scraper 402 is rotatably connected to all the connecting rods 401; and a blocking portion 3007 is provided at the bottom of the powder storage chamber 3002.

[0044] Furthermore, in order to prevent the scraper 402 from being blocked by the protrusion 3006 when sliding in the powder storage chamber 3002, the upper end of the scraper 402 is configured to be curved.

[0045] The material leveling system also includes a top block 403 and a second elastic member 404; a plurality of recesses 1006 are provided on the extrusion table 1; a top block 403 is movably connected in each recess 1006; each top block 403 is located at the lower side of the powder storage box 3; each recess 1006 is fixedly connected with two left-right symmetrical second elastic members 404, and the second elastic members 404 are springs; the second elastic member 404 in each recess 1006 is fixedly connected to the corresponding top block 403.

[0046] A plurality of levers 5002 are arranged on the upper portion of the pressing head 5 .

[0047] When the powder storage box 3 moves forward to prepare for unloading, when the powder storage box 3 drives the pressing head 5 to pass through the top block 403, the top block 403 squeezed by the powder storage box 3 pops out from the recess 1006 under the elastic force of the second elastic member 404, and hits the movable block 201, causing the pressing head 5 to vibrate, which is beneficial to shake off the metal powder in the quantitative chamber 3003 and make the accumulated metal powder evenly distributed in the quantitative chamber 3003. While the pressing head 5 vibrates, it drives the lever 5002 to shake in the quantitative chamber 3003. The vibration of the lever 5002 makes the metal powder further evenly distributed in the quantitative chamber 3003, thereby preventing the metal powder in the quantitative chamber 3003 from being unevenly accumulated and causing pits and agglomerations, thereby avoiding defective products in the stamped workpiece due to uneven distribution of metal powder, and improving the structural strength of the stamped workpiece.

[0048] When the powder storage box 3 moves forward to prepare for unloading, the push plate 4 moves backward in the powder storage box 3, driving the connecting rod 401 and the scraper 402 in a vertical state to move backward together. When the scraper 402 contacts the blocking portion 3007, the blocking portion 3007 blocks the lower part of the scraper 402, so that the scraper 402 rotates to the rear side and fits the bottom of the powder storage chamber 3002. As the push plate 4 continues to move backward in the powder storage box 3, the connecting rod 401 and the scraper 402 fitted to the bottom of the powder storage chamber 3002 move backward to pass over the protrusion 3006. Figure 6 As shown, the scraper 402 passes through the bottom of the metal powder in the powder storage chamber 3002 to prevent the scraper 402 from pushing the metal powder in the powder storage chamber 3002 backwards and avoid the metal powder from accumulating at the rear of the powder storage chamber 3002 .

[0049] When the powder storage box 3 moves backward to prepare for stamping, the metal powder in the metering chamber 3003 has been discharged into the die hole 1002 through the discharge chamber 3004. At this time, the push plate 4 moves forward in the powder storage box 3, driving the connecting rod 401 and the scraper 402 attached to the bottom of the powder storage chamber 3002 to move forward. At this time, the scraper 402 is blocked by the protrusion 3006. When the scraper 402 moves forward, it is blocked by the protrusion 3006 and flips to a vertical state. After the flip, the scraper 402 continues to move forward with the push plate 4, scraping the metal powder in the powder storage chamber 3002 forward until it enters the metering chamber 3003, preventing insufficient supply of metal powder in the metering chamber 3003, and avoiding defective products of the stamped workpiece due to insufficient metal powder, thereby further improving the structural strength of the stamped workpiece.
