Springs in the Medical Industry

 

The medical industry has always been a niche market for the mechanical spring business.  It’s been said that coil springs of some form are used in over ninety percent of mechanically manufactured components and the medical industry certainly has its share.  Spring are used, for example, in inhalers, pill production equipment, hospital furniture, surgical tools, medical implants, monitoring equipment, and orthodontic devices to name a few.

 

The raw spring-tempered materials generally used for medical products are three hundred series stainless steel spring wire.  Many times clean rooms or sanitary spring manufacturing methods are required to manufacture these types of medical springs.  Because of the stringent sanitary demands required by medical spring manufacturing, many times the end user will manufacture their own springs.

 

In order for a spring manufacture to make medical springs they must prove they can meet the clean standards required in the process of medicalspring manufacturing which includes; purchasing stainless steel spring wire, coiling the spring wire, stress relieving, cleaning and passivating.  The medical industry requires that no discoloration to the spring wire is seen after the spring manufacturing process, especially the stress relieving.  This is why medical springs are passivated for the most part.

 

There is good potential for spring manufacturers in the medical spring business as long as the spring manufacturer understands and is willing to meet the requirements of the medical industry.

compression spring is an open coil helical spring that offers resistance to compressive force applied axially. Compression springs are commonly coiled as a constant diameter cylinder, below are several types of compression springs including:

 

 

These are used individually or in conjunction with each other. Round wire is predominant in compression springs because it is readily available and adaptable to standard coiler tooling.

 

Compression springs should be stress relieved to remove residual forming stresses produced by the coiling operation. Depending on design and space limitations, compression springs may be categorized according to stress level . Please view the categories below.

Katy Spring has purchased a brand new 6 – Axes CNC Spring Coiler to arrive Spring of 2012.  The spring coiler CSC-6160N, as it’s referred to, can manufacture compression springs, extension springs, and torsion springs in spring materials up to five and one eights of an inch in diameter.

The CNC spring coiler has the following features:

  1. Windows based software with user-friendly touch screen graphical interface.
  2. Spring outside diameter forming driven by ball screws with two independent servo motors.
  3. Quick shift left hand right hand spring coiling
  4. Rigid Structure and powerful spring wire feeding allowing spring indexes of 3 with oil tempered spring materials
  5. Multi-cut systems for straight, rotary or torsion spring cut
  6. Auto program generator provides different types of spring geometries including hour-glass and banana-shaped springs
  7. 3D spring preview chart analysis for outside diameter, spring pitch, and wire feed
  8. Intuitive programming for spring manufacturing charts
  9. Wire feed displayed by wire feed length and number of coils
  10. Start and end spring coil angles for fine tuning function
  11. Spring taper end spring end coil fine tuning function
  12. Proportional adjustments for outside diameter, pitch, and spring wire forming
  13. Optional external encoder for monitoring spring wire feeding.

The automatic capabilities of this machine are not widespread in the spring manufacturing business and will allow Katy Spring a great advantage in the market place.  More information will be released in the next few months.

 

 

Katy Spring Extension Spring Design Press Release

Katy Spring Extension Spring Design

 

Extension Spring  are used in many applications such as push and pull levers, screen doors, and anywhere else extended spring force is necessary.  Continuous extension springs, such as garter springs, can be used in applications that require metal reinforcement, and can be connected with spring-threaded ends.   A garter spring is also a tension spring that is tightly wound, and can be connected by making one end tapered and screwed into the other end.

Extension springs made are wound with initial tension. Extension spring initial tension is the amount of force required to break the coils apart.  When designing extension springs, certain criterion should be considered such as maximum load, which is determined by spring material type, spring wire diameter, and the application of the extension spring.  An extension spring should be designed within torsion limits of the extension spring material, or about forty percent of the tensile strength of the spring material.

In designing extension springs, other design specifications that should be included are free length; overall or inside the extension spring hooks. Outside diameter of the extension spring body and/or hooks.  The extension spring wire size if preferred or can be referenced and determined by the spring manufacturer if there is an extension spring load or rate.  The number of coils or maximum extension spring body length should be referenced if the spring load is known, extension spring style of ends, right or left hand wound.  What the extension spring’s maximum extended length is…inside the hooks.  How often is the extension spring deflected over the spring’s lifetime?  The position of the extension spring’s hooks…if it’s important to the installation position in relation to the extension spring’s usage.

The extension spring’s ends can come in many varieties including hooks, loops, plain, threaded or extended loops.  The most common are the machine loop and crossover loop and should be specified whenever possible to minimize cost.  Special care should be taken in designing the radius ends as this area can be an area of great stress and shorten the life of the extension spring.  Tool marks and other stress concentrations should be held to a minimum. The minimum bend radius of one and a half times the wire diameter is recommended.

To summarize, the general steps of designing an extension spring are as follows.  Determine if the extension spring has to fit over a shaft.  Determine if the spring is going to fit in a hole.  Does the extension spring need to fit into a fixed space? This would indicate that the extension spring length inside the hooks and the body length need to be at least a certain length or can be no longer than a certain length.  How is the extension spring being used…what is its general function?  This will allow the spring manufacturing engineer to know how much initial tension is needed and how much force the extension spring will need to have in order to perform its desired function.  What types of hooks are required of the extension spring?  Do the extension spring hooks need to have a certain gap between the end of the hook and the body of the spring for a rod of shaft to slide into or are the closed or threaded loops?  Determine what type of spring material will be necessary for this extension spring to function correctly. For example; stainless spring steel or music spring wire, is the working environment corrosive or non-corrosive?  Whenever possible consult a spring manufacturing engineer to help with the final details of your extension spring design.
