Also called spring dowel, is a headless hollow columns body, axial notching two ends have chamfering, used in between the parts localization, the connection, fixed, etc; Must possess good flexibility and shearing force, this kind of pins a little bigger than assembly pore diameter.
Synonyms:Spring dowel pin, elasticity.
Classification:
1. The elastic cylindrical pin 1) light elastic cylindrical pin 2) heavy elastic cylindrical pin light and heavy are the main difference between its material thickness and chamfering width, heavy spring dowel material thickness and width of chamfering than light. 2. Take tooth elastic cylindrical pin 1) light elastic cylindrical pin 2) heavy elastic cylindrical pin and ordinary elastic cylindrical pin shape similarity, difference lies in its axial slotting place for crisscross waves tooth shape. 3. Coiling elastic cylindrical pin 1) light coiling elastic cylindrical pin 2) heavy coiling elastic cylindrical pin
Materials and its mechanical properties:
1) carbon spring steel 2) stainless steel
