Description

Technical Field

[0001] The utility model relates to the technical field of spring steel processing, and more specifically, to a cutting mechanism for spring steel processing. Background Art

[0002] Spring steel is a type of steel specially used to make springs. It has excellent elasticity and fatigue properties. The composition and heat treatment process of spring steel will affect its performance. Common spring steel materials include carbon steel, alloy steel and stainless steel. The selection of appropriate spring steel needs to be determined based on the use scenario, working conditions and requirements of the spring to ensure that the spring can work normally and have a long service life.

[0003] In the existing technology, when spring steel is cut using a cutting device, the spring steel needs to be clamped to facilitate stable cutting of the spring steel. However, current cutting devices generally use bolts to clamp the spring steel, and the clamping speed is too slow, which wastes a lot of time. When using manual cutting equipment to cut spring steel, it is often necessary for someone or equipment to spray water on the cutting surface to reduce the probability of sparks flying and injuring people. Therefore, the spraying treatment link does not meet the production cost-effectiveness, and whether it is someone or equipment, it will lead to an increase in cost. Utility Model Content
