Description

Technical Field

[0001] The utility model relates to the technical field of flat scroll spring processing, and particularly relates to a scroll spring wire tying machine. Background Art

[0002] When a flat scroll spring is installed, it is necessary to keep the scroll spring in a tightly wound state, so as to facilitate mechanical assembly personnel to install it into mechanical equipment. In order to facilitate the assembly of the scroll spring in mechanical equipment, some manufacturers wind the scroll spring after it is manufactured, and tie and package the scroll spring with steel wire. During the installation process of the scroll spring, the steel wire can be disassembled after the scroll spring is clamped into the mechanical equipment, which can reduce the assembly difficulty of the scroll spring.

[0003] Before traditional scroll spring wire tying, it is necessary to tightly wind it to reduce the outer circumference of the scroll spring and then wind and tie the scroll spring with iron wire. However, the winding of traditional scroll springs is carried out manually. For scroll springs with large elasticity, operation errors during the winding process are likely to cause the scroll spring to pop out, causing harm to the hands. Moreover, the manual winding of scroll springs is inefficient and is not conducive to the efficient bundling of scroll springs. Summary of the Utility Model
