Description

Technical Field

[0001] The utility model relates to the technical field of alloy powder processing, in particular to a disc-shaped forming die for alloy powder. Background Art

[0002] Alloy powder disc forming dies are used to press alloy powder into disc-shaped parts or devices. They typically consist of a die body, cavity, and punch, ensuring the alloy powder is formed into parts of the desired shape and size during the pressing process.

[0003] The manufacturing processes for alloy powder disc-shaped molds primarily include cutting, EDM, and precision grinding. The choice of these processes depends on factors such as the mold material, shape, and size. For example, cutting is suitable for large molds, while EDM and precision grinding are suitable for molds with complex shapes and high precision requirements.

[0004] Alloy powder disc forming dies are widely used in aerospace, automotive, machinery, medical equipment, electronic equipment and other fields. In the aerospace field, they can be used to manufacture high-performance parts such as engine blades and turbine disks; in the automotive field, they can be used to manufacture key components such as crankshafts and connecting rods; and in the medical device field, they can be used to manufacture high-performance medical devices such as artificial joints and dental implants.

[0005] In the existing alloy powder disc forming mold, when processing an object, alloy powder is usually added to the processing table, and the alloy powder is pushed by a push plate so that it passes through the processing area and finally enters the processing mold to wait for processing. When pushing the alloy powder, the existing processing device usually pushes it through a straight push plate. During the pushing process, the alloy powder will scatter to both ends of the push rod. This may result in insufficient alloy powder remaining in the processing area when passing through the processing area, resulting in poor quality of the produced parts. Utility Model Content
