The intermediate drawing process is to draw the steel wires to the required diameter by using a straight wire drawing machine. For example, in the intermediate drawing process, the steel filaments are drawn and tapered through a plurality of sets of fixed speed wheel sets and wire drawing cores until a finished product is formed. At present, a wire drawing die set of a straight wire drawing machine adopts a single drawing mode. The wire drawing mold cores between the adjacent constant speed wheel sets are connected with the machine table through the wire drawing mold base.
