What are Compression Springs?

Sep 29th 2015 at 11:22 AM

Compression Springs Shape and Features

The cylinder is the most common shape but many others are used such as hourglass, barrel and conical. As a rule these coil springs are fitted in a hole or set on a rod. When load is placed on the extension springs, it becomes shorter, pushing back on the load while trying to regain its former strength.

These springs are used in different ways and are found in various applications such as stamping presses and automotive engines. These springs are also used in different types of appliances including electronics, phones, medical equipment and various instruments. These springs, in particular the cone types, are found in applications that need greater surge resistance.

Difference between Torsion Springs and Die Springs

These helical springs are widely used because of their resistance to compressive forces. Their elastic properties allows them to store mechanical energy and as was pointed out above they’re available in different sizes and shapes. Die springs are often referred to as high force springs and like the compress springs these can be used even under environmental stress.

Die springs often use a rectangular wire and are most effective with heavy loads or if high temperatures are required. They are in a way, enhanced extension springs or even hybrid, but it does not automatically mean they are superior to regular helical springs.

For instance, there may be instances when you will require a spring for a large clutch or machinery brake. A die spring will do the job, but in many cases a helical spring will be just as effective. Another advantage of these springs compared to die spring is they’re more widely available and can be purchased in large volumes.

If you’re in the market for torsion springs, there’s no shortage of options, and the first thing you should do is assess the situation and figure out which one works best for you. Keep in mind that they are available in different configurations with the straight metal coil being the most prevalent. In many cases this is the most practical and with the diameter uniform across the spring, can be used in different ways.

But that’s not your only option of course. If your compression springs have to be different, look for the convex, conical or concave type as they can be used in various applications. Remember also that manufacturers often add special features to distinguish their products from the rest, so compare these as well.
