SU15344A1 - Wire drawing head for shaped wire - Google Patents

Description

The proposed drawing head with removable cams, mounted on the drawing machine, is intended for drawing the shaped wire in a cold condition.

In FIG. 1 shows a section of the head but lines a-b-e in FIG. 2; FIG. 2 - the view of its origin in the I embodiment of FIG. 3, 4 - the same in the P form of execution; and FIG. 5, 6, the same in the form of execution, but with six cams.

The drawing head (Figs. 1-6) consists of a housing 1 with a flange and a cylindrical part 6, of which the first, provided with holes for fastening bolts, serves to install the head on the drawing machine, and the cylindrical part 6, provided with radial through-bores, serves for mounting cams 2 therein, forming a peephole 8 in the nest 7 of the housing 1, which corresponds to the cross-sectional shape resulting from wire drawing. Thus, FIG. 2, 4, 6 depict three peephole shapes S, corresponding to the three profiles of the wire-square, rectangular and hexagonal sections.

To fasten the cams 2 in the drawing head, a nut b with a conical inner surface and a clamping shaft 5 are used, pressing the cams 3 to the body 1 and being fixed with screws 4 in the head end part, the nut 5 is screwed onto the cylindrical part 6 and sets the cams 2 into position , corresponding to the formation of the eye 8, in which position they are held when the wire is drawn.

The subject of the patent.

A drawing head for a shaped wire, characterized by the fact that it is provided with through grooves for inserting cams 8 into them (Figs 1, 2, 3), forming an eye 8 in the nest 7, for waving a wire, like a head, to strengthen the cams It is equipped with a nut with a tapered internal bore and a clamping bolt 4 fixed in the end part of the head with a washer 5.
