Nine factors that should be paid attention to in spring production

источник:Цянь Точность время:2022-9-14

A spring is a mechanical part that works with elasticity. Generally made of spring steel. It is used to control the movement, buffering or vibration, energy storage, force measurement, etc. of mechanical parts, and is widely used in machines and instruments.

(1) Elastic limit – the elastic limit is related to the tensile strength. Selecting a material with a high elastic limit is usually equivalent to selecting a material with a high tensile strength.

(2) Spring coefficient – the stress applied to the spring material to produce a unit strain is called the elastic coefficient value, which mainly depends on its chemical composition.

   (3) Fatigue strength – fatigue strength must be considered for springs subjected to dynamic loads.

  There is a certain relationship between fatigue strength and tensile strength of materials.

(4) Hardenability – in order to improve the quenching effect, the material is required to have good hardenability, and at least 50% of the central block iron structure shall be quenched.

(5) Shape and size – the mechanical properties of the spring material change with the size. The manufacturing size of the spring material is allowed to have tolerances. Therefore, the material must be selected according to the accuracy of the spring load characteristics.(6) Heat resistance – some springs are used at certain high temperatures. Generally, the mechanical properties of spring materials decrease with the increase of temperature, and the spring performance decreases after a certain temperature.

  (7) Corrosion resistance – when the spring is used in a corrosive environment, the corrosion resistance of the material mainly depends on its chemical composition.

   There are many corrosion factors, so we should grasp the environment and choose materials.

(8) Conductivity – copper alloy series such as brass, phosphor bronze and beryllium copper can be used as spring materials.

   (9) Thermal expansion – expansion caused by temperature change is very taboo for copper rust hairspring, and special materials should be used at this time.

Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. Through continuous efforts, 20 patent certificates and 4 spring equipment software copyrights have been granted by the State Intellectual Property Office, and an enviable industry influence has been built. The company designs and manufactures a wide range of power springs, constant force springs, constant torsion springs, variable force springs and motor brush spring. Qianye works in close partnership with its customers in developing bespoke solutions to meet their individual needs. In order to offer better services, it has been continuously investing in production technology and supply chain. The company itself is a stainless steel raw material manufacturer. Because of the support of raw materials, it is not subject to material restrictions when making spring products; special material requirements can be developed and manufactured; furthermore, the delivery time is greatly shortened. Quality is of the utmost importance and Qianye are certified to ISO9001, ISO14001 and national high-tech enterprise with a big emphasis on the training of its employees. Its spirit is “treat people with sincerity and create things with sincerity” to ensure it strives for excellence.
