Design technology of high precision spring

source:Qianye Precision time:2022-9-14

 Spring to ensure good elastic performance, that is, absorb a lot of elastic energy without plastic deformation; Sufficient plasticity and toughness to prevent impact fracture. According to the stress nature, the spring can be divided into tension spring, compression spring, torsion spring and bending spring. According to the shape, it can be divided into dish spring, ring spring, plate spring, spiral spring and truncated cone scroll spring.

      The design process of spring has the following points:

     1. Device space: design a compression spring, clearly understand the space required to install the spring, and then you can master the basic manufacturing conditions, outer diameter, inner diameter and free length of a compression spring.

     2. Movable stroke load: the design of compression spring to clearly understand the position to be actuated and the elastic force to be carried. Determine the position and know the required elasticity, then you can determine the material, wire diameter and number of turns.

   3. Environmental factors: when the spring is actuated in different environments, it will be affected by environmental factors and affect the service life. Therefore, the designer takes into account the changes of ambient temperature and humidity. The temperature has a great impact on the service life of the spring, and the humidity is easy to oxidize the spring without surface treatment. Therefore, environmental factors can determine whether the spring needs surface treatment and material selection.

     4. Distance space between two ends: stretching the points at both ends of the spring will affect the form of the hook and the free length of the tension spring. Space can determine the size and outer diameter of the dense part.

    5. Pre tension load: the pre tension load determines the material and wire diameter of the spring, and the pre tension length can be adjusted according to the size of the close part.

6. Outer diameter of the spindle: the inner diameter of the torsion spring can be determined according to the size of the spindle, but the change of the spring body after torsion needs to be considered, so an appropriate margin can be reserved.

      7. Inner diameter of device space: if the device of a torsion spring adopts the “in” type, the “in” type space shall be considered. Space determines the outer diameter, free length and number of turns of the spring body.

       8. Torsion fulcrum: when the torsion spring works, there is a fulcrum, which can determine the length and form of the torsion bar.

        9. Starting and ending point of action: the angle position between the force application torsion bar and the fulcrum when no work is done. The length and form of the force application torsion bar and the angle with the fulcrum bar can be clearly specified.
