Description

Technical Field

[0001] This utility model relates to the field of wire drawing equipment technology, and in particular to a fully automatic wire drawing device for edge strip components. Background Technology

[0002] Wire drawing and polishing is commonly used for surface finishing of hardware parts, creating a wire-like polished surface that improves the smoothness and aesthetics of the hardware parts and products. For wire drawing of strip-shaped parts, there are two common processing methods: manual wire drawing and polishing, and wire drawing and polishing using a triangular wire drawing machine. In existing technology, a triangular wire drawing machine includes a polishing platform, a pressing component, and a moving abrasive belt wound in a triangular shape. The strip-shaped part is fixed to the polishing platform using customized tooling fixtures. Then, the pressing component presses down on the bottom edge of the abrasive belt, ensuring its abrasive surface is in close contact with the target polishing surface of the strip-shaped part. The moving abrasive belt polishes the target polishing surface of the strip-shaped part, while the moving pressing component moves laterally along the length of the strip-shaped part, completing the comprehensive wire drawing and polishing process on the target polishing surface.

[0003] Strip-shaped parts are special objects for wire drawing and grinding, characterized by their narrow and long processing surfaces. Existing triangular wire drawing machines have several drawbacks when performing wire drawing and grinding on strip-shaped parts: 1. Only one or two strip-shaped parts can be wire drawn and ground simultaneously in each wire drawing and grinding cycle, resulting in low processing efficiency; 2. When wire drawing and grinding strip-shaped parts, because the width of the abrasive surface of the abrasive belt is larger than the width of the processing surface of the strip-shaped parts, the abrasive belt is prone to edge flipping during operation, and the abrasive surface of the abrasive belt cannot be used more effectively, resulting in waste; 3. Only long and thin wire drawing textures can be processed, and short and fragmented textures cannot be ground on the surface of strip-shaped parts, resulting in limited functionality.
