heat resistance SWPA yellow / blue Industrial Compression Springs
TRY Spring description:
TRY Spring is especially designed for the stamping mold / plastic
mold ; TRY spring can have a powerful motivation in a small space
to compare with the round wire coil spring . DAI spring has the
type of lightest load spring , light load spring, medium load
spring , heavy load spring , super heavy load spring , hyper heavy
load spring , and the hight deflection spring . TRY springs are
easy for choosing because they are coating by their own different
color.The SUS304WPB material has the performance of high stress ,
high amplitude and the excellent heat resistance , the durability
is improved compare with the shot peening process.
Widely used in automobiles, motorcycles, electrical appliances,
telecommunication, craft, toys ,locks,stationery,furiture ,washing
machines,vacuum cleaners,lamps and lanterns,bicycles,sports
Electronic products, Children’s toys, Locks, Watches, Glasses,
Baby carriage, Bicycle, Kitchen appliances, Cameras, Printers,
equipment, Precision equipment and various kinds of vehicles
DAI Spring Choosing Method
Take the exactly 4 data for Working Load, Spring Outside Diameter,
Using Time, and the Deflection before choose our DAI spring .
1. Working Load 13.61 N
2. Spring Outside Diameter 18.0 mm
3. Using Time 4,000,000-time Use
4. Deflection 60 mm
Look at the below Load Curve by 1,000,000-time Use, focus on the
vertical axis of Load ( kgf ) by 100kgf, find the crossing point
from the horizontal axis of Outside Diameter by 25mm, we can know
the load grade information.
Based on the Load Curve, by 1,000,000-time Use, when the deflection
is 25mm, the below RED 25-100 spring was selected:
|wire diameter(mm)||Outside Diameter(mm)||inside Diameter(mm)||Free Length(mm)||constant(N/mm)|
When you use DAI Spring, please observe the following instructions.
Use Over Maximum Deflection (4000,000-time Condition) (Use Near
As illustrated in the drawing on the right hand, use over
300,000-time condition will be become the use around solid length.
Around the solid length, since the number of active coils will
become gradually coherent, the spring constant will become higher,
and as illustrated, the load characteristic rises and becomes high
stress, which would cause damage to products. Please refrain from
using over 300,000-time condition.
Use without Initial Deflection
Use with any space will give impact and cause damage to spring. Be
sure to use with the initial deflection of 1mm or more.
Use by Nipping Scrap or Foreign Articles
As illustrated in the drawing on the right side, when any foreign
articles is caught in spring, such part will not work as number of
active coils, and the number of active coils will substantially
become reduced, which would cause higher spring constant and damage
to spring. Also, the solid length will become longer.
Use Where the Parallelism of Mounted Surface Is Not Good:
Bad parallelism of mounted surface would cause twisting or damage
to spring. Be sure to check the parallelism.
Do not use without spring guide
Use without spring guide would cause twisting or damage to spring.
Be sure to use spring guide such as shaft or outside diameter
When the using environmental temperature becomes higher,
substantial function loss will occur. Be careful about using
1: High quality with competitive price.
