Abstract

The invention discloses a forming device and a forming method of powder metallurgy part. The forming device and the forming method of the powder metallurgy part comprise a feeding vessel and a formingmodule, wherein the feeding vessel comprises a base and a plurality of front sealing covers for selecting and mounting, a rear sealing cover and a plurality of separation plates, at least two feedingpipes are arranged on each front sealing cover; the number of the feeding pipes on each front sealing cover is different, a discharging hole is formed in the base, and the discharging hole is in buttjoint with the forming module; the front sealing cover is connected with the rear sealing cover and covers the top of the base, each feeding pipe of the front sealing cover extends into the discharging hole, and each separation plate is arranged on the inner wall of the rear sealing cover, and every two adjacent feeding pipes are separated by each separation plate. The method comprises the stepsof S1, mounting; S2, feeding; S3, pressing; S4, mold stripping; S5, sintering; and S6, circulating the steps from S2 to S5. The forming device and forming method of powder metallurgy part has the advantages of being simple in structure, convenient to operate,and high in forming efficiency and stability.

Description

technical field [0001] The invention mainly relates to powder metallurgy technology, in particular to a molding device and a molding method for powder metallurgy parts. Background technique [0002] Powder metallurgy is a process in which metal powder raw materials are used to obtain workpieces through typical processes of mixing, molding, and sintering. Powder metallurgy has the characteristics of net shape, energy saving and material saving, stable production, and high stability in mass production. At present, the production is generally based on a single material, and there is no automatic production method for two different mixed materials. The manual filling method has the disadvantages of inaccurate control and unstable production. [0003] Different parts of powder metallurgy parts require different functions, and it is determined that different parts require different components of materials to be manufactured. At present, there are two types of connection methods ...
