Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a material cutting device used for metal spring processing. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under external force and returns to its original shape after the external force is removed. It is also called a "spring" and is generally made of spring steel. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc. According to the nature of the force, springs can be divided into tension springs, compression springs, torsion springs and bending springs.

[0003] Metal springs need to have their raw materials cut during processing, but current cutting devices for materials to be processed usually rely on manual fixation during cutting, which is prone to tilting and displacement, difficult to fix, and inconvenient for cutting to a fixed length, resulting in a poor operating experience.
