For modern mechanical engineering, both domestic and global, a significant expansion of the range of parts belonging to various structural groups, in particular of the screw type, is characteristic. An important place among them is occupied by strip helical blanks, as evidenced by a steady trend toward increasing production volumes and expanding application fields. Such blanks are widely used in the food, chemical, and processing industries, as well as in agricultural machinery manufacturing and other industrial sectors.The aim of this work is to conduct theoretical studies of the force parameters of the operation of winding strip helical blanks onto a mandrel for the design of specialized technological tooling.
A device design for manufacturing wound strip helical blanks is presented. Its advantages include improved quality of forming wound strip helical blanks due to the prevention of stability loss of the wound turns in the lower part of the mandrel, as well as expanded technological capabilities of the device by enabling the formation of turns with a pitch greater than the strip thickness. Based on the developed computational scheme, theoretical studies of the force parameters of the operation of winding strip helical blanks onto a mandrel for the design of specialized technological tooling have been carried out. Analytical relationships have been derived that make it possible to predict the force parameters of the process depending on the design parameters of the required strip helical blanks. On the basis of the presented equations, the required technological tooling for winding strip helical blanks can be designed. In this case, in order to reduce the winding torque of the strip helical blank, and consequently to decrease the power required to perform the process, it is necessary to reduce the coefficients of friction between the working surfaces of the roller and the outer edge of the strip blank, as well as between the strip helical blank and the groove of the auxiliary holder, for example, by using lubricants. Graphs of the dependence of the winding torque of a steel strip helical blank and the force of winding the strip onto the mandrel on the strip design parameters have been constructed.
It has been established that an increase in the strip thickness and width leads to a significant quadratic growth of both the winding torque of the strip helical blank and the force of winding the strip onto the mandrel, which must be taken into account when designing technological tooling and selecting equipment.l torque.
