The extension spring is a helical spring that bears the pressure. The material used in it is mostly circular in cross-section, and it is also rolled with rectangular and multi-stranded steel coils. The spring is generally of equal pitch. The shape of the extension spring is: cylindrical , Conical, convex and concave shapes and a small amount of non-circular shapes, etc. There is a certain gap between the coils of the tension spring, and the spring shrinks and deforms when subjected to an external load to store deformation energy.
The strengthened round spring of the extension spring, due to its spiral geometry, is more difficult to strengthen than the flat surface of the leaf spring. In addition, it is necessary to strictly evaluate the strengthening effect of the circular spring cross section, so as to fully understand the resistance of the circular spring to fatigue fracture.
The round springs are individually sent to the shot blasting room via a continuous conveyor chain system. A set of parallel roller tables are installed in the shot blasting room. While strengthening, the roller tables keep rolling, driving the round springs to move forward while rotating. This way of rotation allows the high-speed pill flow to pass between the rings of the circular spring and hit the metal surface of the inner ring, where the stress of the circular spring is most concentrated.
For applications with high productivity requirements, an enhanced device that can spray two round springs at the same time can be selected. The latest research and development result is based on the original shot blasting equipment, combined with multiple nozzles, used for more targeted and concentrated shot peening for the specific area of the round spring (stress concentration to please).
