Description

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder as raw material, and then manufactures metal materials, composite materials and various types of products through molding and sintering. For metal parts with low strength requirements, the powder metallurgy process is used to produce them. Compared with other processes for producing metal parts, the production cost is greatly reduced.

[0003] Existing powder metallurgy equipment usually includes a frame, which is equipped with a platform for setting tooling. The platform has an integrated mold.

The mounting frame 301 extends to the top of the mold 6. The bottom of the powder box 303 is fixedly connected to an L-shaped push plate 32. The mounting frame 301 is provided with a sliding opening for the L-shaped push plate 32 to slide. One end of the L-shaped push plate 32 is fixedly connected to the outer bottom wall of the powder box 303. The other end of the L-shaped push plate 32 passes through the sliding opening and extends to the lifting mechanism 4. The L-shaped push plate 32 can push the mold 6 at the lifting cylinder 401 to the conveying platform 503. The distance from the L-shaped push plate 32 to the lifting mechanism 4 is smaller than the distance from the powder box 303 to the mold 6. When filling the mold 6 with powder, the electric push rod 302 is driven to push the powder box 303 to the top of the opening 7 of the main body 601, and the metal powder is poured out from the powder pouring port 31. At the same time, the L-shaped push plate 32 pushes the mold 6 on the first carrying plate 402 to the conveying platform 503, which is convenient and quick.

[0040] Implementation principle: First, place the first body 601 between the two loading plates 1802, then start the loading electric push rod 1801 to make the two loading plates 1802 push the body 601 to the lifting port, and at the same time start the lifting cylinder 401 to make the first carrier plate 402 rise and close the lifting port, then start the powder pouring mechanism 3 to pour the powder, then put the cover plate 602 into the body 601, and then start the stamping mechanism 2 to stamp, after the powder is compacted, start the loading electric push rod 1801 to clamp the body 601, lock the body 601 and the cover plate 602, then remove the stamping mechanism 2, and then start the loading electric push rod 1801 to release the mold 6, and start the lifting cylinder 401 to make the mold 6 drop to the same level as the conveying platform 503 At the same horizontal height, the powder pouring mechanism 3 is started again to push the first mold 6 into the conveying platform 503, and then the lifting cylinder 401 is started to rise and close the lifting port. At this time, the second body 601 is placed between the loading plate 1802, and the above operation is repeated. After completing the stamping of the second mold 6, the lifting cylinder 401 is started to descend, so that the powder pouring mechanism 3 sends the second mold 6 into the conveying platform 503, and the second mold 6 pushes the first mold 6 toward the heating box 502 until it reaches the second supporting plate 2502, and then continues to convey the mold 6, so that the previous mold 6 enters the heating box 502, and at the same time the next mold 6 is conveyed to the second supporting plate 2502, thereby maintaining the bearing weight of the second supporting plate 2502.
