Due aspetti da considerare nella progettazione di una molla a forza costante

fonte:Precisione di Qianye volta:2022-9-15

Il molla a forza costante is made of stainless steel strip. The high strength steel strip is shaped by specific spring production equipment. When the external force is straightened, the hair strip will naturally roll back and produce elastic force. However, to achieve our goal, we can return to the designated starting point after displacement.

    Molla a forza costante has the characteristics of maintaining constant force in a long stroke. Its function can be applied to the adjustment of lifting doors and windows, computer monitors and fans, shopping mall display shelves or motor carbon brush motors and other products that require linear motion such as round trip, sliding, stretching, homing, balance or force saving.

So how to design the constant force spring in line with product performance ? We generally need to consider from two aspects :
    1. Performance of constant force spring
   The two most important properties of the constant force rod are elastic value and life. The thicker the elastic               material, the wider the width, the higher the elastic force. Among the materials with the same size, the smaller the     crimp diameter is, the higher the elasticity is, and vice versa. On the contrary, under the same manufacturing             conditions, the thinner the material is, the better the life is. In the same size of the material, the smaller the coil
diameter is, the shorter the life is, and vice versa.
    2. Installation space of constant force spring
   Generally, the outer diameter of the spring is set according to the installation space. Sometimes, when the middle      shaft is used, the inner diameter must be taken into account at the same time. The outer diameter of the spring
cannot be larger than that of the installation space. Otherwise, friction will occur and affect the use.
    Qianye precision selection of stable raw materials manufacturers, our constant force spring is made of stainless steel 301 materials. Engineers will customize suitable spring materials according to customer requirements to achieve the best design effect. Other high-carbon steel and manganese steel materials can be customized. But the company ‘ s business in recent years to high-end line development, only consider making 301 stainless steel. Through self-developed molding equipment, the consistency and stability of product quality are ensured, and the fatigue resistance is greatly superior to the similar products in the market.
    Shenzhen Qianye Precision Metal Co., Ltd. is a manufacturer specialized in providing high-precision spring. The company integrates product R & D, production, sales and services, and has engineering and management personnel with various technical skills and rich experience. Has successfully passed ISO9001, ISO14001 and TS16949 professional qualification certification. We sincerely welcome new and old customers and friends from all walks of life to visit the company to guide, negotiate business cooperation, Qianye Precision will sincerely serve you !
