Hardware springs mainly based on daily-use machinery and electrical appliances, such as mattresses, sofas, door hinges, toys, lighters, etc., such springs are in high demand, but the technical content is not high, which increases the development opportunities for small spring enterprises This type of spring is mainly developed in the direction of miniaturization.
Electronic appliance springs mainly based on instruments and meters, typical products include motor brush springs, switch springs, camera and camera springs, computer accessories springs, instrument accessories springs, etc. In this type of spring, leaf springs and special-shaped springs account for a large proportion, and the materials and technical requirements of different products vary greatly. This type of spring is mainly developed in the direction of both high strength and miniaturization.
Large springs and leaf springs, mainly railway rolling stocks, trucks, and construction machinery, which are mainly hot-rolled, are an important aspect of the spring manufacturing industry. With the development of high-speed railways and the upgrade of vehicle shock absorption systems, the technology of thermoformed springs as vehicle suspensions has been greatly improved. Such springs are mainly developed in the direction of high strength and high precision to stabilize product quality.
For chemical plants, valves, oil, and power springs, typical products are chemical plants, valves, oil, and power springs. In this type of spring, leaf springs and special-shaped springs account for a large proportion, and the materials and technical requirements of different products vary greatly. This type of spring is mainly developed in the direction of both high strength and miniaturization.
Special springs mainly to meet special needs, such as cradle springs for textile machinery, require high resistance to relaxation; springs for ladle runners require high heat resistance; suspension springs for mine shakers not only require It has high fatigue performance and requires high corrosion resistance, so rubber-metal composite springs are used: in order to meet the comfort of the vehicle when driving, air springs are used.

1. Why does the stainless steel spring appear "lack of elasticity" (1) The design and manufacturing parameters of non-standard springs are unreasonable: only pay attention to the parameters such as outer diameter, inner diameter and length, and often ignore the size of the wire rod cross-sectional area and pitch, resulting in insufficient elasticity;
1. What surface defects often occur in automobile springs (1) Cracks in automobile springs are mainly caused by the material manufacturing process. The cracks extend in the drawing direction, the depth can be from a few millimeters to more than 1 millimeter, and are distributed longitudinally. Cracked materials cannot be used to make springs.
China is a big country producing stainless steel, which is widely used in the field of springs, especially small springs. With the development of stainless steel production, many varieties have been developed naturally. More than 50 types have been developed at present, which basically meets domestic production. And development needs. Briefly introduced some new varieties currently developed.
1. How to make the spring material 1. Grinding (1) The process of refining iron ore into iron in a furnace (blast furnace) is called grinding ore. The outside of the furnace is a steel plate
Precautions for clutch spring maintenance: The performance of the clutch spring will be weakened after long-term use. It is important to maintain the clutch spring. How to maintain the clutch spring? Today we come to talk about the precautions for clutch spring maintenance.
Dear users: Hello! First of all, thank you for your long-term care and support for Shanghai Precision Metal Products (Shenzhen) Co., Ltd.!
The hardware industry is brewing five major changes, of which spring accounts for a certain percentage. According to customs statistics, in 2010, the total import and export of China's hardware industry reached US $ 74.923 billion. A year-on-year increase of 30.1%, of which exports totaled US $ 57.51 billion, an increase of 31.4% year-on-year; imports totaled US $ 17.412 billion,
Although the hardware spring industry can be said to be a small industry in the entire manufacturing industry, its role in various major fields cannot be underestimated. The national industrial manufacturing industry and the automotive industry must accelerate development, while the spring industry As one of the basic parts and components, to adapt to the rapid development of the entire national industry requires a super early stage of development.
1. The development trend of the spring industry in various fields (1) At present, the processing equipment and production lines of mechanical springs are developing towards the depth and breadth of numerical control and computer control.
I believe that everyone often goes shopping and sees that there are a lot of hairdressers. Among them, the electric hair clipper is an essential thing. Generally, all kinds of hair clippers and hair clippers use double torsion springs. Due to the need to cut hair through movement and coordination with the cutter head system,
