Description

Technical Field

[0001] This utility model relates to the field of metal wire forming technology, and in particular to a metal wire forming device for precision packaging. Background Technology

[0002] Stainless steel wire is a commonly used metal wire in precision packaging. It possesses excellent corrosion resistance, resisting the erosion of moisture, oxygen, and some chemicals in the air. For example, when packaging electronic components with high requirements for humidity and chemical stability, such as chips and integrated circuits, stainless steel wire ensures that the packaging's airtightness is not compromised by corrosion during long-term storage and transportation. Its high strength allows it to withstand certain tensile forces, providing a reliable fastening effect when sealing packaging.

[0003] A problem exists in the use of metal wire in precision packaging: when the wire is cut, burrs appear on the end face. For products used in precision packaging, these burrs may affect the packaging's airtightness. If the burrs puncture the packaging material, such as plastic film or aluminum foil, it will compromise the integrity of the packaging, allowing the product to be affected by external environmental factors, such as air and moisture, thus impacting the product's quality and shelf life. Furthermore, in some packaging applications where appearance is critical, burred wires can also detract from the packaging's aesthetics.

[0004] In industrial production, specialized grinding equipment can remove burrs more efficiently. For example, a belt grinder is used to grind the cut end of a metal wire through a belt. This method is suitable for processing large quantities of metal wire, and the desired grinding effect can be achieved by adjusting parameters such as the grit size of the belt and the grinding speed.

[0005] The existing metal wire processing involves: ① cutting the wire to the required length; ② grinding the end face of the wire mechanically; and ③ shaping one end of the wire into the required shape. The processing can only be divided into steps, resulting in low production efficiency. Utility Model Content
