Sheet metal disc spring with a rectangular cross section wound spiral spring toy frustoconical spring, conical coil springs with circular cross-section which characteristic line is similar. The main feature is the small size, load, variable stiffness; widely used in small spaces, load bearing and shock absorber big occasions. Truncated cone spiral spring by spring parameters and carrying case classification, can be divided into the helix angle, etc., etc. pitch, stress and other three forms, namely: ① such as helix angle truncated cone spiral spring, ② etc. truncated cone spiral pitch spring, ③ and other stress truncated cone spiral spring. The spring design and manufacture complex than those commonly used materials 60Si2MnA, 50CrVA, surface treatment methods are blue, painting and so on. Please specify when ordering free height, maximum deformation, maximum diameter, minimum diameter, maximum load, thickness, plate width, the working circle, total laps. We can use your spring conditions, the selection of suitable materials, and satisfy your needs.

Spring washer under the nut is installed, with its tension spring, with a special wrench to tighten the nut to the required standards moment after locking nut can play the role. At present, all are in a tense speed up grid construction and transformation, porcelain and other components when installed, be sure to install the spring washers to ensure the quality of power grid construction and transformation, project quality will directly affect the safe operation of the line. Spring washer is not installed, if the hot summer months, the line of continuous operation at high temperatures, thermal expansion and contraction of the metal, bolts, nuts after heated, produces loose nut trends; encountered windy weather, the wind blowing on the wire twisting pendulum shock spring, spring washers do not have protection, over time, will accelerate the loose nut. Its consequences and harm can be imagined. Therefore, a large area power grid construction and transformation, not just to progress, the easy way, but ignore this small part of the tension spring | Spring | Xufeng Hardware Factory provided by the Dongguan City, Xu-feng Hardware Products Factory.
