The Length of Shank Portion for Closing Head is defined as the amount of rivet shank needed to form a proper shop head. It is calculated by subtracting the combined thickness of the plates being joined from the total length of the rivet shank.
The calculator uses the formula:
Where:
Explanation: This formula calculates the amount of rivet material needed to form a proper closing head by accounting for the material that will be consumed in joining the two plates.
Details: Accurate calculation of the shank portion length is crucial for ensuring proper rivet formation and joint integrity. Insufficient material may result in an improperly formed head, while excess material can lead to waste and potential joint issues.
Tips: Enter the total length of the rivet shank and the thicknesses of both plates being joined. All values must be positive numbers measured in meters.
Q1: Why is this calculation important in riveting?
A: This calculation ensures there is adequate material to form a proper shop head while maintaining the structural integrity of the riveted joint.
Q2: What happens if the shank portion is too short?
A: If the shank portion is too short, it may not provide enough material to form a complete and secure closing head, compromising the joint strength.
Q3: Can this formula be used for multiple plates?
A: This specific formula is designed for two plates. For multiple plates, the formula would need to be adjusted to account for additional thicknesses.
Q4: What units should be used for input values?
A: The calculator uses meters as the standard unit, but any consistent unit system can be used as long as all inputs are in the same units.
Q5: How precise should the measurements be?
A: For optimal results, measurements should be as precise as possible, typically to at least 0.1 mm accuracy for engineering applications.
