Description

Technical Field

[0001] The invention relates to the technical field of magnetic material forming and processing, and in particular to a multi-station magnetic powder material forming and production device. Background Art

[0002] In the production of magnetic materials, there is a process for initially extruding the magnetic powder material into a shape, and then further processing it in subsequent steps to make it a magnetic material product used in various mechanical and electronic products.

[0003] At present, the processing equipment configuration of magnetic powder material molding in some factories requires an extrusion molding machine, a molding die, a magnetic powder weigher and two operators; the extrusion molding machine is used to extrude and mold magnetic material products, and the mold cavity of the molding die is used to load magnetic powder. The molding die used here is movable and detachable. The magnetic powder weigher is used to weigh a certain weight of magnetic powder and introduce the magnetic powder into the mold cavity of the molding die. The molding die is placed in the extrusion molding machine for extrusion molding.

[0004] Here, two operators, A and B, are used to describe the operation. Operators A and B are located on both sides of the extrusion molding machine respectively. Operator A is responsible for pouring the weighed magnetic powder on the scale into the molding cavity of the molding mold, and then pushing the molding mold into the extrusion molding machine. After the extrusion molding is completed, the molding mold is taken out of the extrusion molding machine, and the mold is disassembled to expose the molded product. At this time, operator B takes the molded product out of the mold, puts the product into a packaging bag, and puts the packaging bag into a vacuum machine for vacuuming. After the vacuuming is completed, the packaging bag is placed in a product placement box. After the product placement box is full, the product is moved to the subsequent workstation for subsequent processing. At the same time, operator A takes the molding mold for assembling, and then continues to pour the weighed magnetic powder into the molding cavity of the molding mold and repeats the process. Operators A and B cooperate with each other to perform the molding processing of the magnetic powder material.

[0005] In the magnetic powder molding production process, since the magnetic powder material is an easily oxidized material and is in powder form, the machine is equipped with a protective cover, and the protective cover is a sealed protective cover filled with nitrogen. The entire working space is a nitrogen space. Operators A and B work by wearing gloves set on the protective cover and operate through the observation window opened on the protective cover.
