Our MD Alex Driver has recently signed up to become a STEM Ambassador; he is the first of many John Binns’ employees that we hope will be signing up to become ambassadors. This means he is now part of a community of 30,000 ambassadors across the UK. STEM refers to Science, Technology, Engineering and Mathematics subjects. STEM Ambassadors are volunteers from the age of 17 that represent a vast range of STEM-related jobs and disciplines across the UK. They [...]
Springs are very often overlooked in the design process of new products. It is no exaggeration to say that they are a key functional component in most mechanical devices and that, without a properly designed spring, the products functionality and lifespan is adversely affected. The spring is often considered a small and inexpensive part of a much larger article, therefore the designer will recognise that there is a requirement for a spring, but may leave the specification of the [...]
The initial tension is released, when a tension spring is extended to a certain point, where gaps appear between the coils.
The rate is the strength of a spring as defined by Hooke's law. Hooke's Law states that the force needed to extend a spring is directly proportional to the distance you stretch it. Hooke's Law can be represented as F = ks. 'F' is the spring's restoring force 'k' is the spring constant 's' is the deflection (extension)
Counting coils on a tension spring is the same as counting coils on a compression spring. The type of ends on a spring will make no difference to the number of coils.
How spring loads work within a tension spring. If too much weight is applied to the spring it will no longer contract, therefore breaking the spring.
How to measure the length of a tension spring.
How to measure the diameters of a tension spring.
The next video in our Springtelligence series shows you how to allow for tolerances in spring manufacture.
As the Brexit deadline of 29th March is fast approaching, we feel that it is necessary to communicate to you some points around our Brexit strategy. The main focus of our business is to satisfy the demands of you, our customers. Through the turbulent times ahead our commitment to supply first class parts in a timely fashion will not change. However, we all understand that there will be increasingly difficult trading circumstances under whatever Brexit route the UK finally [...]
