| description | This article justifies the use of hand operated percussion machines with a linear electromagnetic drive for connecting building reinforcement in steel cylindrical bushings. The most suitable percussion energy was selected for connecting reinforcement with a diameter of 10-14 mm, which is most often used in floor slabs and building foundations. Having compared the crimp and welded joint tensile strength, it was found that the quality of such joints is comparable. With the help of the “operator — machine — workpiece” model system, the most vibrational phases of the shock cycle of the percussion machine were identified, and using the machine model as an oscillating system, frequencies were determined at which vibration acceleration measurements should be performed. It has been experimentally established that the level of vibration load during pressing reinforcement is within acceptable values, however, there is a need to reduce vibration load on the device body. The results of the research show that with the help of hand operated percussion machines with a percussion energy of 50 J, it is possible to connect building reinforcement Ø10-14 mm. At the same time, it is necessary to improve the design of known machines to ensure vibration safety. |
