This online metric bolt torque calculator is used to find … The calculator is generic an can used for imperial and metric units as long as the use of units are consistent. 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. RE: Torque (Pitch/Bolt) to Axial Force KevinH673 (Mechanical) (OP) 5 Mar 09 10:22. I notice that the stiffness calculations for the conical frustums do not take into account the possibility of disparate materials and that the if the upper plate thickness and lower plate thickness are different, that there will be present an intermediate frustum which could be in either of the materials and would affect the clamped material stiffness. In order to keep the mold closed, this force must oppose the separating force, caused by the injection of molten plastic into the mold. 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. Too much clamping force can also cause severe problems. Instructions Formula Send us your comment. Do the math backwards from that force (torque) to the clamping force. 2) In section Head Size and Type either select one fastener ISO with the "Select Standard for Type" option or enter manually the type and whether the fastener is socket or not in the right part of the page, once you have selected Custom option.. 3) Enter strength class of the fastener. Only emails and answers are saved in our archive. Learn about the process cycle and design for manufacturing (DFM) guidelines for a wide range of manufacturing processes, including injection molding, metal casting, machining (milling and turning), and rapid prototyping. As the clamping force is a linear function of both the turning angle of the screw and the pitch of the thread, there is a direct relation between the clamping force and the tightening torque within the elastic range of the screw elongation. When various factors are typed into the Input cells, Excel will calculate results automatically. by Skype or
The calculation is carried out in metric or English units. Calculation of thread strip safety according to new VDI 2230-1:2014. clamping energy shown on the torque-angle plot has the same value as the areas under the bolt and clamped component lines in the Force-Deformation Diagram (refer to Figure 9). T dry = (0.2) (20000 lb) (0.75 in) (1/12 ft/in) (1 - (0%) / (100%)) = 250 (lb f ft) When various factors are typed into the Input cells, Excel will calculate results automatically. Compare this against the rated torque spec and duty type for the gearbox. I would just try it and see if it works. You can target the Engineering ToolBox by using AdWords Managed Placements. The required clamping force can be calculated from the cavity pressure inside the mold and the shot projected area, on which this pressure is acting. See the instructions within the documentation for more details on performing this analysis. The clamping force on a bolt is defined as the compressive force a fastener exerts on a joint. See the reference section … Metric bolts and nuts are rated in newtons per square millimeter (N/mm 2 or pascals). 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. In the real world (when clamping force is important) ,a hydraulic tensioner pulls the stud/bolt and then the nut is tightened. See table below for how much clamping force is available from manual clamp straps of various sizes (with a 2-to-1 clamping-force ratio) to compare with power-clamp forces. Google use cookies for serving our ads and handling visitor statistics. The clamping force on a bolt is defined as the compressive force a fastener exerts on a joint. The clamping force is required to prevent joint movement being caused as a result of axial and/or shear forces. Typical values for K with mild-steel bolts in range 1/4" to 1": Note! Metric Bolt Torque Calculator. This fastener bolt torque calculator will Estimate the unknown torque, diameter, axial force applied and coefficient of turning friction for the given conditions. Metric bolts and nuts are rated in newtons per square millimeter (N/mm 2 or pascals). There are variables that affect the clamping force calculation, like the material type (low-flow versus high-flow plastic), and the depth of the part. Thanks again for your advice Roy. 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. See Torque Force Design Equations webpage and torque chart page for recommended fastener torque and equation data.. 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. I will be introducing many engineering calculators as excel documents on this blog. Sometimes an approximate method is good enough. Most accurate bolt torque calculator given its geometry and thread diameter, using vdi 2230 standard, Screw Clearance through the specific tool 3D model. Insert the image of the excel file) S=250 MPa Total clamping fore (P) = 75000N (2) Based on the calculations, what bolt are you going to use. During the bolt tightening process, the length of the bolt increases and it behaves like an extension spring. I do agree and I suggest the following changes. Tightening Torque for Unlubricated Steel Bolts. The required bolt clamping force for a joint is 20000 lbs. © 2007-2020 MoreVision Ltd. All Rights Reserved. Obviously, this cross-sectional area is different for each size of bolt. Welcome to our technical resource library! Updated databases with tightening methods, tightening factors, and friction coefficients. BOLTCALC - Bolted Joint Analysis Program: bcdemo.exe (7.87 MB) TORQUE - Torque Tightening Analysis Program: torquedemo.exe (5.14 MB) All of them will be posted in the “Resources” tab for easy access. This is way above what the bolt can handle and fatal failure is likely. Be aware that the shaft collar moves when you tighten its clamp bolt. I am curious, why do you need to calculate the force? T dry = (0.2) (20000 lb) (0.75 in) = 3000 (in lb) = 3000 (in lb) / 12 (in/ft) = 250 (ft lb) Calculation of a bolted connection with prestress. Washers also serve to distribute the preload and applied force over a larger area, both on the bolt head and on … Pipe Stress due to Clamping Force Spreadsheet Calculator. The Bolted Joint Analysis calculator allows for stress analysis of a bolted joint, accounting for preload, applied axial load, and applied shear load. Example - Required torque for tightening a Imperial bolt. by mobile, EU +44 113 8152220
Grab it with the collet and then apply force to that arm until it slips. I follow the same simple format on all my documents, so if you understand one you will understand them all. Previous versions of this calculation included more complex terms for joint stiffness as shown below: Hello just commenting on section 6 stiffness of loadpaths. 1) Enter thread diameter nominal value in section Thread Size.Click on info button for more info. Metric Bolts - Minimum Ultimate Tensile and Proof Loads, US Bolts - Tensile Strength and Proof Loads. Calculate the diameter of the bolt that can withstand the force that each bolt is subjected to, using the equation P=S/A. Make a Shortcut to this Calculator on Your Home Screen. Total stiffness of all compressive loadpath elements under bolt 6) Calculate Basic Joint Forces Force in bolt when preload is lost (joint separates and contact force between clamped plates = 0) Fbreak/Fleak: resulting safety factor 7) Calculate bolt loads for a particular external load applied to the joint External load applied to the bolted joint ( mechanical ) ( OP ) 5 Mar 09 10:22, and friction coefficients force calculator clamping....
