Description

The invention provides a device for orienting a cut off from meta. Listochko sheet edge relative to the throat of scissors.

When |) cutter with chdvestvuyuscheyu |; With disc knives, the edges of the nose under the action of large forces, caused during the cutting process, are deformed and curled by HiTonopoM, changing the size of the next cut pieces of the edge.

The proposed design eliminates this drawback, due to the supply of the chute with movable upper and lower slats, which allow straightening the cut edge and orienting it relative to the scissors throat.

On fmg. 1 shows a device with a throat of short-cutting scissors; in fig. 2 is a section along the SS and DD in FIG. one; on fng. 3-position of the sheet edge in the device in the transverse position, and.

The structure is eo6oi cast steel gutter / s O1 with a removable side wall 2, equipped with adjustable lower and upper

As soon as the sheet is nonadust is circular knives 5 and 6, the edge on the lugs nlanok 4 and 3 is cut in the same frame / outside the cutting zone, marked 20 (fng. 5). Both planks create a direction of twisting, opposite to that which it naturally acquires when it is separated from the sheet in the cut zone. The dimensions of the nlanok are chosen from the calculation so that when an angled angle is reached, i.e., the edges are twisted, it doesn’t appear that it is bent to the yield strength of the material being cut, resulting in an edge at the exit of the sunroof from the tank and the same.
