Functions of Flat Springs and How They Work

Flat springs are flat strips of material that store and release energy when deflected by an external load. Flat springs are small stamped metal components that act as springs by controlling deflection in small or restricted spaces. Leaf springs can also be used as spacers or grounding.

Leaf springs are an important component in suspensions, for example in cars or other vehicles, providing stability and helping to minimise wear and tear on other components. They are flat springs made from individual layers or sheets of metal. Leaf springs are commonly used in the design and repair of vehicles, including drive or steering shafts.


Leaf springs

Leaf springs are one of the oldest forms of springs, dating back to the Middle Ages, and they are an important component of suspensions, for example in cars or other vehicles. They provide stability and help to minimise wear and tear on other components.

They are made from individual layers of metal or metal leaves and are often used in automotive designs for drive or steering shafts.

Flat coil springs

Flat coil springs are used in conjunction with counterweights to control the action of valves, such as those in automotive exhaust systems. They are wound into specific configurations to absorb shock or provide tension and can be found in seats to provide support or in automotive applications.


The work of leaf springs

When a vehicle goes over bumps, the axle tends to move up and down. However, thanks to the provision of leaf springs, they support the axle and help to absorb vibrations and shocks.

Let's understand how it works with an example!  Suppose a train goes over a speed bump, which causes the wheels and axles to be forced upwards. Therefore, as the axle moves upwards, the leaf spring moves with it, but because of its semi-elliptical shape, it absorbs the upward force and transmits it to the chassis frame. The unbuckle of the leaf spring helps it to expand as it is stressed.  

They are used in a variety of applications in different industries, such as motors, office equipment, generators, balancing, doors and electrical switchgear.

Steelmaking Process (2)

8. Refining period: The process of steelmaking is carried out by slagging and other methods to remove some elements and compounds that are harmful to the quality of steel by chemical reaction into the gas phase or discharged into the slag to remove it from the molten steel. period. 9. Reduction period: In the ordinary power electric arc furnace steelmaking operation, the time from the completion of the slag slag to the tapping is usually called the reduction period. 10. Furnace refining: The steelmaking process of refining the molten steel in the steelmaking furnace (converter, electric furnace, etc.) to another vessel for refining, also called secondary metallurgy. The steelmaking process is therefore divided into two steps: primary refining and refining. 11. Steel liquid agitation: Stirring of molten steel through refining beyond the furnace. It homogenizes the molten steel composition and temperature and boosts metallurgical reactions. Most metallurgical reaction procedures a...

Crane rail installation - Standards and procedures

图片
   Introduction to crane track installation With the rapid development of modern logistics, greater demands are being placed on the logistics management of machinery and equipment. This is not just about transporting bits. Once heavy machinery or equipment has arrived at a facility, it also needs to be picked up, moved and set up appropriately. For these purposes, cranes come in very handy. As cranes play an important role, crane track installation also plays an important role in these industries.  Crane track installation Techniques and standards The accurate installation of crane rails is a primary requirement for this type of heavy machinery and related industries. Selecting the most suitable track and securing it is a key issue in ensuring the integrity and longevity of the crane track system. At Yongyang , we have a reliable, skilled and experienced team to help you find the more suitable crane rails. But more on that later. Now let's talk more about crane rail inst...
