Product Description

Product Description

A range of compression springs from our Bosswinn offer, available in various sizes and lengths, with closed and ground or closed not ground end types. Compression springs are highly popular as they can store a large amount of energy in a small space, making them ideal for a wide range of applications.

These Bosswinn compression springs, also referred to as coil springs, have varying degrees of stiffness, also known as spring rate. Coiled springs are designed to return to their original height when compressed, helping to keep components separated and functioning properly.

Bosswinn offers a great selection of compression springs with wire diameters ranging from 0.2 to 2.2 mm and spring rates from 0.06 N/mm to 22.56 N/mm.

 



1. Structure
 
  • The wire is coiled around an axis, forming a helix. The pitch, which is the distance between adjacent coils, remains relatively constant throughout the spring. The outer diameter of the coil can vary depending on the design requirements, and the thickness of the wire (also known as the wire gauge) is selected based on the amount of force the spring needs to withstand.
  • For example, a tightly - wound coil spring with a small pitch and thick wire will be stiffer and able to handle larger loads compared to a spring with a larger pitch and thinner wire.
 
2. Materials
 
  • Steel:
    • High - carbon steel is commonly used as it offers high strength and good elasticity. It can endure significant stress and is suitable for applications like automotive suspensions, where the springs experience repetitive and heavy loads.
    • Stainless steel is preferred when corrosion resistance is crucial. This makes it ideal for use in marine environments or in medical equipment, where the spring needs to maintain its performance over time without rusting.
  • Alloys:
    • Alloys such as beryllium copper are used in specialized applications. They combine the properties of good electrical conductivity with spring - like behavior, making them useful in electrical switches and connectors where a spring - loaded mechanism is required to ensure proper electrical contact.
  • Plastics:
    • In some cases where cost - effectiveness and lightweight design are important, plastic coil springs are used. They are often found in toys or in some low - load consumer products, where they can provide a simple and inexpensive spring - like function.
 
3. Functions and Applications
 
  • Shock Absorption:
    • In the automotive industry, coil springs are an essential part of vehicle suspensions. When a car drives over a bump, the coil springs compress, absorbing the kinetic energy of the impact. As the wheel moves back to its normal position, the spring expands, releasing the stored energy. This helps to smooth out the ride and reduce the vibrations felt by the passengers.
  • Force Application:
    • In industrial machinery, coil springs are used to apply a specific force. For instance, in a punch press, the coil spring provides the necessary force to drive the punch into the material being processed. In a garage door mechanism, the coil spring helps to counterbalance the weight of the door, making it easier to open and close.
  • Consumer Products:
    • Coil springs are present in many everyday items. In a ballpoint pen, a small coil spring is used to push the ink cartridge forward when the pen is pressed, ensuring a continuous flow of ink. In a mattress, coil springs are used to provide support and comfort, distributing the weight of the sleeper evenly across the surface.

Design Considerations for Machinery Springs

When designing or selecting machinery springs, the following factors are critical:

  1. Load Requirements: The spring must withstand the expected forces without permanent deformation.

  2. Deflection: The spring should provide the required range of motion or compression.

  3. Spring Rate (Stiffness): The force required to compress or extend the spring by a unit distance.

  4. Fatigue Life: The spring must endure repeated cycles of loading and unloading without failure.

  5. Environmental Conditions: Consider factors like temperature, corrosion, and exposure to chemicals.

  6. Space Constraints: The spring must fit within the available space in the machinery.

 

Manufacturing Process of Machinery Springs

  1. Material Selection: Choose the appropriate material based on application requirements.

  2. Coiling: The wire is coiled into the desired shape using CNC coiling machines.

  3. Heat Treatment: Springs are heat-treated to enhance strength and durability.

  4. Surface Finishing: Coatings or finishes (e.g., zinc plating, powder coating) are applied to prevent corrosion.

  5. Testing and Quality Control: Springs undergo rigorous testing for load capacity, deflection, and fatigue life.

 

Standards for Machinery Springs

Machinery springs are often manufactured to meet industry standards, such as:

  • ISO 9001: Quality management systems.

  • ASTM International: Standards for material properties and testing.

  • DIN (Deutsches Institut für Normung): German standards for spring design and manufacturing.

2. Workcraft (Manufacturing Processes)

2.1. Material Selection

  • Materials: High-carbon steel (ASTM A228), stainless steel (SUS 304), phosphor bronze, or Inconel for high-temperature applications.

  • Quality Check: Verify material certifications and perform chemical composition analysis.

 

2.2. Coiling

  • Process: The wire is coiled into the desired shape using CNC coiling machines.

  • Precision: Tight tolerances are maintained for wire diameter, coil diameter, and pitch.

  • Tools: CNC spring coiling machines, mandrels, and guides.

 

2.3. Heat Treatment

  • Purpose: To relieve internal stresses and enhance durability.

  • Process: Springs are heated to 250-400°C for 30-60 minutes, followed by controlled cooling.

  • Result: Improved fatigue life and load-bearing capacity.

 

2.4. Surface Finishing

  • Purpose: To prevent corrosion and wear.

  • Processes:

    • Zinc Plating: Provides corrosion resistance (5-15 µm thickness).

    • Powder Coating: Adds a protective layer (50-100 µm thickness).

    • Shot Peening: Enhances fatigue resistance by inducing compressive stresses.

  • Testing: Salt spray tests (ASTM B117) to evaluate corrosion resistance.
