Description

Technical Field

[0001] The present invention relates to the technical field of wire processing, and in particular discloses a small wire forming machine. Background Art

[0002] Today, with the continuous development of the manufacturing industry, wire forming machines play a crucial role in many fields. With the increasing diversification and refinement of the demand for various parts and products in industrial production, the requirements for the quality, efficiency, and precision of wire forming are also getting higher and higher. With the advancement of the industrialization process, some semi-automatic wire forming equipment has emerged, but these equipment have limited functions and low automation levels. They can often only complete wire forming tasks of a single type or specification, lacking flexibility and versatility. In some complex wire forming requirements, such as those requiring high-precision bending angles, specific shapes and sizes, traditional equipment often struggles to cope, resulting in products that cannot meet the design requirements, increasing the scrap rate and production costs.

[0003] Facing the intensifying market competition and the higher expectations of consumers for product quality, the existing wire forming technologies and equipment are already difficult to meet the rapid development needs of the industry. There is an urgent need for a wire forming machine with higher production efficiency, higher precision control, better finished product quality, and better applicability and versatility in dealing with different wires. Summary of the Invention
