FORMING PROCESS OF SCREW SPIKE IN DOUBLE CONFIGURATION

Summary. In this paper technology of screw spikes manufacturing, based on the flashless forging and hot rolling in double configuration, is presented. The forging takes place in closed dies and the obtained workpiece is rolled in its middle part on cross-wedge rolling mill in order to make screw thread. As the result of this process, it is possible to eliminate disadvantages of the former technology: flash and groove on the head surface of the workpiece thread part. The new technology designing based on computer simulations and experimental research, which considerably lowered the costs of implementation. The advantages of using the new technology include: improving the finished product functional quality, increasing of productivity and obtained economic effects.
