Description

Technical Field

[0001] The utility model relates to the technical field of alloy powder forging, in particular to a hard alloy powder forging feeding device. Background Art

[0002] Cemented carbide powder forging technology combines the advantages of powder metallurgy and precision forging. After pre-pressing metal powder into shape, it is forged under high temperature and high pressure to obtain high-density, high-strength, and high-toughness cemented carbide products. This technology not only overcomes the shortcomings of low density and unstable mechanical properties of traditional powder metallurgy parts, but also significantly improves the density and mechanical properties of the material, allowing cemented carbide materials to better adapt to complex and changing industrial environments. In addition, cemented carbide powder forging technology also has the advantages of high material utilization, precise forming, and high production efficiency, providing strong technical support for the large-scale production and application of cemented carbide.

[0003] The forging of cemented carbide powder mainly includes several key steps, including raw material preparation, preform pressing, sintering, forging and post-processing. Among them, preform pressing is a core link. In this process, the uniformly mixed cemented carbide powder is placed in a special mold and pressed by a press machine under a certain pressure. During pressing, the size and distribution of the pressure must be strictly controlled to ensure close contact between the powder particles and initial metallurgical bonding to form a preform with a certain shape and density. This preform will serve as the basis for subsequent sintering and forging, and its quality and shape are extremely demanding. By precisely controlling the various parameters in the pressing process, high-quality preforms can be obtained, and then cemented carbide products with excellent performance can be prepared.

[0004] In the prior art, the forging process of cemented carbide powder is to first centrally feed the material above the die through a feeding device, and then complete the forging through a forging device. However, this feeding method has significant disadvantages: it often causes some die holes to fail to be fully fed, and some powder will flow to locations outside the die holes. This situation not only requires the insufficiently fed die holes to be refilled before forging, but also requires additional cleaning and recovery of the powder outside the die holes, thereby adding unnecessary work processes and greatly reducing work efficiency. In addition, this uneven feeding mode may also affect the quality consistency of forged products, resulting in fluctuations in product performance and increasing the difficulty of subsequent quality inspection and screening. In the long run, this inefficient and error-prone production method will increase production costs. Utility Model Content
