Description

The proposed tool for making warp hairpins is an ordinary convolution, in which a central channel corresponding to the diameter of the hairpin is applied, in order to obtain screw cutting edges for machining a square billet into a cylinder.

In FIG. 1 is a side view of the tool; FIG. 2 is a top view of the tail; FIG. 3 shows a section along the line AB in FIG. one; FIG. 4 -: - a section along the line CD in FIG. one; FIG. 5 is a view from the direction of the guide plate.

The proposed tool is a conventional screw drill bit, in which the central channel b is drilled (Fig. 1), corresponding to the diameter of the stud, in order to obtain screw cutting edges d for machining into a square billet cylinder. The latter is inserted through the central hole in the plate a associated with the drill bit (Figs. 1, 2 and 5). equipped with a number of pyramidal projections / (Fig. 5). These protrusions are intended to form the cutting edges d in order to remove part of the material from the corners of the square billet before it enters the central channel b for final turning.

The hairpin coming out of the b channel turns out to be completely smooth, not requiring the use of pelt.

 the invention.

A tool for the manufacture of warping pins, which is used in an ordinary screw-drill of a central bore channel corresponding to the diameter of a pin b in order to obtain screw cutting edges d for machining a square billet into a cylinder through a central hole provided with a row pyramidal protrusions / in order to form cutting edges d for removing a part of the material from the corners of a square billet before leaving it to the channel b.
