Description

Technical Field

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

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and return to their original shape after the external force is removed. It is also called "spring" and is generally made of spring steel. There are many types of springs. According to their shapes, there are mainly spiral springs, scroll springs, leaf springs, special-shaped springs, etc. After the spring is coiled, there will be excess steel wire at both ends of the spring. Therefore, the spring needs to be cut to make it easier to use. When cutting the spring, the spring needs to be fixed to facilitate cutting.

[0003] However, the existing spring cutting and fixing device cannot clamp and fix the spring according to the size of the spring when in use, and cannot be adjusted and fixed according to the length of the spring, so that the practicality of the fixing device is not high. It cannot be adjusted and fixed according to the thickness of the spring. In addition, the existing fixing device requires the staff to rotate the spring by themselves so that the part of the spring that needs to be cut is aligned with the cutting device, and it cannot be rotated and adjusted by itself. It is inconvenient to fix springs of different lengths and diameters, and has poor applicability. Utility Model Content
