The working principle of the plastic spring is as follows: when the plastic spring is under downward external force, the shape of the middle circular corrugated pipe is stressed and deformed under the action of force, and an upward resilience force is generated at the corner R of the outer part after the plastic spring is compressed. When the downward external acting force disappears, the angle R rebounds after deformation, and the spring resets. Meanwhile, the plastic spring is made of a high-elasticity, heat-resistant molecular material, and has a high elastic deformation coefficient because the part is deformed by an external force, otherwise, the rebound function cannot be effectively realized. As is well known, the deformable body made of common materials is soft, and particularly is easy to shrink seriously under a high-temperature state to cause permanent deformation so as to lose the function of the deformable body, but the deformable body made of high-elasticity and heat-resistant molecular materials has the characteristic of high heat resistance, is not influenced by high-temperature shrinkage to reduce the elasticity, can still deform and recover normally at high temperature, and greatly improves the product quality and prolongs the service life.
In summary, the oil pump is an optimized structure of a full-plastic spring used for a press type oil pump, and is mainly applied to daily product packaging products, the press type oil pump products on the market are basically provided with normal up-and-down springback effects of steel wire springs made of S316, 304H and the like, but the steel wire springs are limited in subsequent recycling and utilization, and have the factors of environmental protection, difficult degradation and the like.
