Large and hot coiled compression springs
Contents |
[edit] Introduction
Compression springs are a widely used across several different sectors of manufacturing, from engineering to trains. Being one of the first to have been invented, it is one of the most popular types of spring.
Hot coiled compression springs undergo a heated treatment, to produce their hardened and sharpened surface, and can be tailor-made specifically to meet customer requirements.
Large compression springs are open coiled springs which are wound from a purpose made machine in the distinct helical shape and can produce a considerable amount of force, suited for application in large-scale manufacturing operations.
[edit] How They Are Made
In the process of making a hot coiled compression spring, a wire bar, varying in size, length and width is austenitised, or heated to around 850°C, to change its crystal structure and render it more malleable. It is then formed into its coil shape around a large machine, dropped into oil to cool, and finally processed to give the finished product.
In a similar process to hot coiling, large compression springs are fed into a purpose-built machine, which uses force to spin the spring into its helical shape. Due to the size, they are normally ‘caught’ on a tray, where they are processed into the final product.
[edit] Applications
[edit] Railway Industry
Both large and hot coiled compression springs are used within the railway industry.
There are two main suspension systems widely used in the manufacture of trains. The first being the primary suspension system, which uses springs to support the structural suspension of the carriage and the entire train.
The secondary suspension system focuses on the comfort of passengers through creating an airbag-like effect, in a process called pneumatic suspension. This is also used in freight transportation to reduce the impact of the movement from the journey on fragile goods.
[edit] Offshore Industry
Springs are common components in offshore industries, due to their durability, strength, and ability to withstand highly-exposed environments. Large and hot coiled compression springs are suited for this industry, as they are a much larger, stronger alternative, and can be tailor-made to fit any machine or use.
[edit] Other Applications
Other applications include:
- The electric power industry.
- The mining and construction industry.
- Paper and pulp manufacture.
- The automotive industry.
Large-scale, durable components are essential in these fields, not only due to their functional aspects but also for their impressive safety features.
[edit] Sizes Available
The size of both types of these springs vary completely due to the requirements of the customer. Lengths can be up to 1500 mm, 600 mm in width, and bar/wire width can be up to 65 mm.
All springs can be made to measure and come in a range of finishes, suitable for any specific job specifications.
