Metric Bolt Torque Calculator. They are of two types, metric flange bolts and metric hex bolts. A simpler version of this calculation is available here. by mobile, EU +44 113 8152220
Metric Bolts - Minimum Ultimate Tensile and Proof Loads, US Bolts - Tensile Strength and Proof Loads. Then you calculate (I think) the needed clamping torque of the clamp on rod 2, by equating it to the torque applied by a 50 lb force on rod 1. Clamping Force Calculator is a tool to calculate the Clamping Force in the injection molding machine based on the different area’s like part projected area, runner projected area, cavity pressure and number of cavities. UN bolts and nuts are rated in pounds per square inch (psi). Hello responding to comment on joint stiffness from brab2. Bolt Science - Providing solutions to bolting problems. In the real world (when clamping force is important) ,a hydraulic tensioner pulls the stud/bolt and then the nut is tightened. The calculation is carried out in metric or English units. Obviously, this cross-sectional area is different for each size of bolt. See the instructions within the documentation for more details on performing this analysis. Poor method to get a known clamping force; frictions are large unknowns. Tightening torque to preload a bolt Metric thread : M1 M1.2 M1.6 M2 M3 M4 M5 M6 M8 M10 M12 M14 M16 M20 M24 M30 M36 M42 - 3.6 4.6 4.8 5.6 5.8 6.8 8.8 9.8 10.9 12.9 Make a Shortcut to this Calculator on Your Home Screen. Bolt Clamping Force vs. Loading by axial or tangential force. This calculator can be used to calculate the force acting in a bolt. Calculation of thread strip safety according to new VDI 2230-1:2014. Grade 5 … a 200 ton machine is capable of producing a maximum clamping force equivalent to a total of 200 tons. The reduced torque can be calculated, Eq. Obviously, this cross-sectional area is different for each size of bolt. Calculation of a bolted connection with prestress. *Clean, dry clamping stud torqued to approximately 33% of its 100,000 psi yield strength (2:1 lever ratio). Be aware that the shaft collar moves when you tighten its clamp bolt. Bolts that are fully or partially threaded, with washers and nuts are called as metric bolts. Solon Manufacturing's resource library is filled with high-quality industrial pressure switch and Belleville spring product information. Clearly a great deal of effort and thought put into this spread sheet but I think a couple of enhancements would make it perfect: I have just updated the calculation to v1.2. For everyday purposes the clamping force can be approximated by measuring the tightening torque. When various factors are typed into the Input cells, Excel will calculate results automatically. This is can be dependent on a number of factors, but is largely a function of the preload force, the force exerted in compressing the bolt, and the tension force, the force exerted in pulling the bolt apart. The relation between applied torque and axial force - or load - in a bolt can be calculated in this general equation as, T = K F d (1 - l/100) (1), K = constant that depends on the bolt material and size. Fc=Fp – [Kj / (Kb + Kj)]* Ft…………..eq1. - be aware that this is a rough calculation where the screw pitch is not included. Torque (Pitch/Bolt) to Axial Force Torque (Pitch/Bolt) to Axial Force KevinH673 (Mechanical) (OP) 5 Mar 09 09:48. This online metric bolt torque calculator is used to find … You could make a test piece with a lever arm. Pipe Stress due to Clamping Force Spreadsheet Calculator. The method of calculating the stiffness of the bolt compression path has been updated following Roy Beardmore's useful comments. Use a Torque Calculator. Therefore, it is necessary to adjust the clamping … See the reference section … Presented below are links to pages on specific topics related to bolted joint technology.We specialise in this subject and have extensive knowledge and experience on the solution of problems related to bolted joints.
