Flat Springs

Flat springs are flat strips from a material which can be used to store and at the same time release energy when an external load is used to deflect. Such kinds of springs are small and metal-stamped constituents that work as a spring by regulating the deflection that takes place in small or restricted areas.

A flat spring is manufactured from a combination of nickel-silver, carbon spring steel, stainless steel, beryllium copper, phosphor-bronze, and high-nickel alloy. As a result, it can be used as a ground or a spacer.

Application of Flat Springs

Flat springs have a wide range of shapes and sizes, therefore, they are suitable for numerous applications. Due to this, they can be used for different purposes in different industries such as motors, generators, office equipment, counterbalances, and electrical switchgears.

Flat springs come in different kinds such as leaf springs and flat coil springs. Here are the types:

Flat Coil Springs

These type of springs are used with a counterweight so that the action of the valves are well controlled. Such valves can be those in the exhaust system of a vehicle. They are twisted into a specific configuration so that it is able to absorb shocks as well as provide tension. They are used in seating so as to give enough support and it is used in automotive applications too.

Flat springs come in different sizes, shapes, and materials. This makes them perfect for any purpose. More so, they can be used either as electrical conductors or leaf springs. However, their common function is to hold other assembly parts in a firm position.

This component can also be used together with smaller punch presses so as to lower the amount of tooling that is commonly needed for other production methods. In most cases, these flat springs are bent, formed, shaped or even manufactured so that they meet a specified application requirement. Therefore, they are not tightly coiled wires as most people think.

Due to the variation of its shape and size, a flat spring has the ability to pack sufficient force and flexibility even if space is small. So when picking or ordering a flat spring this December, ensure that it fits your requirement and the purpose so that you do not regret using it.

Extension springs are used in both heavy industry and in domestic tools and machinery; from the cars, we drive to the motorbikes or even to the pens we use. Springs are essential in the construction industry. Heavy machinery as well as minutely accurate scientific equipment use springs to provide the necessary contact pressure, to balance loads and ensure smooth and safe operation. Depending on the method of force application, springs can be divided into two main categories, Compression and Extension Springs.

Extension springs

Extension springs, also referred to as tension springs, work by resisting pulling forces of two moving parts of an application. The extension spring stretches, absorbs the energy and then will pull back to it's closed (free) position.
The variables that are considered in making extension springs include; end configuration, material, end types, length, number of coils, spring shape and diameter. Tension springs also have special hooks on their ends which are used to attach within an application. These hooks are available in various configurations; including full loops, half loops, extended hooks, machine hooks, and crossover centre loops.

Stainless steel and Music wire are the two most popular materials used in making extension springs. These materials can also be modified depending on your needs. The springs can be coated with zinc plating, or any other coating to suit your needs.

Applications

Extension Springs are also customised to fit into various forms. With the right design properties, these springs are essential throughout industry. Common uses of tension springs include:

• Balancing heavy engineering. High load, high stress engineering products. Stamping machines, press brakes, CNC machines, drop presses. All require springs to damped the shock and force of operation.
• Belt balancing.  Moving high, variable mass product along belts requires load balancing to ensure safe, smooth operation.  both compression and extension springs are utilised to ensure safety and efficiency.
• Industrial vehicles and load transportation equipment. Springs are required to balance load, ensure driver or operator comfort and most importantly ensure the safety of the vehicle, operator and those around it.
• Garage doors: Tension springs are used to ease the upward movement in garage doors.
• Automotive uses: Tension springs are used in various vehicle parts. One of them being in carburettors.
• Vice-grip grip tools such as pliers: This type of pliers can be tapped in a specific position where it can be used as vice grips. Extension springs are used to keep the grip tight.
• Farm machinery: Most parts of farm machinery utilise extension springs the same way vehicles do. Extension springs are used in ploughs, graders, bulldozers and harvesters.
• Washing devices: These springs are used in dishwashers and washing machines to keep the tub balanced. These washers are made using a specific type of extension springs known as suspension springs.
• Medical devices: Quite a number of medical devices have extension springs. These include surgical lights stretchers, and some small handheld devices.
