Solution of a suitable method of production of contactor forgings

Abstract

This paper discusses a suitable method to manufacture contactor forgings, depending on the size of the series. A suitable semi-finished product and the method of cutting have been proposed. The design of a suitable forming machine and forging tools was carried out for the production of contactor forgings in the number of 10,000 pieces and 50,000 pieces per year. The LE 160 eccentric press was designed to cut the sprue. A comparison was made between the production of contactor forging on the pneumatic-hydraulic hammer KHZ 4 A and the production on the mechanical crank press LKM 1600. The die design was carried out for both production alternatives. The cost analysis for the production of one piece of forging showed that for a large number of pieces, it is more economical to forge using a mechanical forging press.
