Spring Recoil Hose For Checking

A Method for Making a Gauge for Stretching Spring

Stretch spring is a kind of elastic element, in the process of winding, the spring wire around its own axis torsion, each circle and tight, with a certain compression force, bear the axial tension of the spiral spring, stretch spring is generally made of circular section material.  

Extension spring is widely used in auto parts, such as the accelerator pedal return spring, drum brake return spring and electronic throttle actuator return spring, these parts of complicated structure, have higher request for flexible machining accuracy, mechanical property, tensile spring manufacturing process including rolling, hook manufacture, heat treatment, process test and shot peening treatment, machining error exists,  Therefore, it is necessary to test the finished stretch spring to improve its reliability.
