Abstract

Upsetting force is a very important factor. It determines quality, efficiency and avoids defects when stamping tubes. In this study, the design of measuring system of upsetting tube force on the crank stamping machine was investigated. A principle of force sensor was placed in the mold system on the crank stamping machine. The principle of force sensor was based on piezo electricity, the deformation stamp was applied as a sensitive element for the sensor. The sensor has performed the function in receiving and transforming information about the variation of the force on the input into the voltage variation on the output. This output signal has been sent to the signal processing center and displays the measurement results. These results were used to compare and evaluate the results of the numerical simulation process. Also, the results of measurement of upsetting force with different cases were given and compared with the results of theoretical calculations
