Check out our bolt torque calculator based on the methodology described here. Bolt torque calculator metric (vdi 2230) Bolt torque calculator metric. Obviously, this cross-sectional area is different for each size of bolt. 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. The required bolt clamping force for a joint is 20000 lbs. All of them will be posted in the “Resources” tab for easy access. The required bolt clamping force for a joint is 20000 lbs. Calculated Values: • Shot Projected Area(in2) • Separating Force(tons) • Clamping Force… ... (controlled clamping of the joint). This is way above what the bolt can handle and fatal failure is likely. Norbar has devised easy-to-use online calculators that support the correct application of torque in three key areas: Unit conversion to assist international measurement definitions. by Skype or Please read AddThis Privacy for more information. Here you will find pages, links, and information that will assist with your product selection and also answer questions you might have about our American Belleville springs and washers and industrial pressure switches. Bolt Science - Providing solutions to bolting problems. I do agree and I suggest the following changes. When various factors are typed into the Input cells, Excel will calculate results automatically. The Bolted Joint Analysis calculator allows for stress analysis of a bolted joint, accounting for preload, applied axial load, and applied shear load. Hello responding to comment on joint stiffness from brab2. The Bolted Joint Analysis calculator allows for stress analysis of a bolted joint, accounting for preload, applied axial load, and applied shear load. 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. In addition, the powerful tool, "Goal Seek" can be used to optimize each Calculation. A simpler version of this calculation is available here. by Skype or Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! The simplest way by far is to select a prospective bolt, calculate the clamping force this creates when it is torqued to rated torque, and use the bolt circle as an approximation of the moment arm. You can look up the recommended tightening torque for a given fastener size in my bolt sizing calculator or in a table like the one found here. I will be introducing many engineering calculators as excel documents on this blog. However, only about 10% of the torque applied is transferred into clamping force. In order to keep the mold closed, this force must oppose the separating force, caused by the injection of molten plastic into the mold. The amount of force on a fastener is called as torque. Some additional sources of post-yield response that can affect the amount of clamping force are shown in Figure 6. a 200 ton machine is capable of producing a maximum clamping force equivalent to a total of 200 tons. Poor method to get a known clamping force; frictions are large unknowns. In the real world (when clamping force is important) ,a hydraulic tensioner pulls the stud/bolt and then the nut is tightened. Only emails and answers are saved in our archive. During the bolt tightening process, the length of the bolt increases and it behaves like an extension spring. Use a Torque Calculator. This online metric bolt torque calculator is used to find … Below is a screen shot of the bolt sizing calculator. These applications will - due to browser restrictions - send data between your browser and our server. Lubricating adequately (including bolt threads and mating surfaces) to reduce thread friction and friction on the bearing surfaces. The calculations within this live spreadsheet will facilitate the initial design and engineering of many types of bolted and riveted joints. 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). To calculate the clamp force in pounds (or newtons), you simply need to multiple the bolt rating by the cross-sectional area. The required bolt clamping force for a joint is 20000 lbs. Compare this against the rated torque spec and duty type for the gearbox. The simplest way by far is to select a prospective bolt, calculate the clamping force this creates when it is torqued to rated torque, and use the bolt circle as an approximation of the moment arm. In addition the accuracy of a torque wrench is normally no better than +-25%. 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. For ordinary applications like car wheel lugs or headbolts , the manufacturer has the experience to know the torque levels to apply. In order to keep the mold closed, this force must oppose the separating force, caused by the injection of molten plastic into the mold. + Toggle System: It is “toggle link”. (Show all calculations. Example - Required torque for tightening a Imperial bolt. AddThis use cookies for handling links to social media. The torque required for a 3/4″ dry steel bolt to achieve this tension can be calculated as. Solon Manufacturing's resource library is filled with high-quality industrial pressure switch and Belleville spring product information. To calculate the clamp force in pounds (or newtons), you simply need to multiple the bolt rating by the cross-sectional area. Thread Diameter. Where Does the Fastening Energy Go? 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. Step-by-step illustrated examples show how to use the spread sheet tools to optimize bolted joint designs. UN bolts and nuts are rated in pounds per square inch (psi). Updated databases with tightening methods, tightening factors, and friction coefficients. See the instructions within the documentation for more details on performing this analysis. Since bolt holes could have sharp edges or burrs, washers are used to protect the fillet under the bolt head from scratching since this is a critical area that is prone to failure. 3) Slip force times radius = slip torque. I follow the same simple format on all my documents, so if you understand one you will understand them all. © 2007-2020 MoreVision Ltd. All Rights Reserved. 1) Enter thread diameter nominal value in section Thread Size.Click on info button for more info. Bolt Science - Information related to bolted joints. 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. Google use cookies for serving our ads and handling visitor statistics. Very interesting Roy. Fc=Fp – [Kj / (Kb + Kj)]* Ft…………..eq1. 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. For ordinary applications like car wheel lugs or headbolts , the manufacturer has the experience to know the torque levels to apply. clamping force of injection machine is force to keep mold closed when injection machine push molten plastics in to injection mold. Clamping Force Calculator Clamping force refers to the force applied to a mold by the clamping unit of an injection molding machine.
