Abstract

A method for producing a cutting unit segment of a cutting unit of a machine tool separating device, includes at least one cutter support element and at least one cutter element. In at least one step, the cutter element is molded on the cutter support element by a drawing process in an at least partially staggered manner relative to an outer surface of the cutter support element.

First claim

The invention claimed is:

1. A method for producing a cutting strand segment of a cutting strand of a power-tool parting device, the method comprising:
integrally forming at least one cutting element on at least one cutter carrier element with a set relative to an outer surface of the at least one cutter carrier element by tensile forming;
forming a connecting cutout in a first surface of a first region of the cutter carrier element;
integrally forming a connecting element extending from a second surface of a second region of the cutter carrier element in such a way that the connecting element has a third surface, which is coplanar with the first surface; and
embossing the connecting element so as to integrally form a transverse securing element on the connecting element in such a way that the transverse securing element couples the cutting strand to a further cutting strand segment and secures the cutting strand segment against movement relative to the further cutting strand segment.

2. The method as claimed in claim 1 , wherein the integral forming of the at least one cutter carrier element includes embossing the at least one cutting element with the set relative to the outer surface of the at least one cutter carrier element.

3. The method as claimed in claim 1 , further comprising:
punching the cutting strand segment from a band material before integrally forming the cutting element to form the cutter carrier element.

4. A cutting strand of a power-tool parting device comprising:
a first cutter carrier element;
a first cutting element integrally formed on the first cutter carrier element with a first set relative to an outer surface of the first cutter carrier element by tensile forming;
a second cutter carrier element offset along a cutting direction from the first cutter carrier element; and
a second cutting element integrally formed on the second cutter carrier element, wherein:
the first cutter carrier element includes a first region having a first surface, a first connecting cutout being defined in the first region in the first surface,
the first cutter carrier element includes a second region having a second surface parallel to and recessed from the first surface, the second region including a first connecting element extending integrally from the second surface so as to form a third surface, which is coplanar with the first surface,
the second cutter carrier element includes a third region having a fourth surface, a second connecting cutout being defined in the third region in the fourth surface,
the second cutter carrier element includes a fourth region having a fifth surface parallel to and recessed from the fourth surface, the fourth region including a second connecting element extending from the fifth surface so as to form a sixth surface, which is coplanar with the first surface and the fourth surface,
the first connecting element interacts with the second connecting cutout so as to pivotably mount the first and second cutter carrier elements relative to one another, and
the fourth, fifth, and sixth surfaces, the third and fourth regions, and the second connecting element are all formed integrally with one another.

5. The cutting strand according to claim 4 , wherein a transverse securing element is integrally formed on the first cutter carrier element, the transverse securing element interacting with the second cutter carrier element to secure a movement of the first cutter carrier element along a transverse axis.

6. The cutting strand as claimed in claim 5 , wherein the transverse securing element is formed on the first connecting element.

7. The cutting strand according to claim 4 , wherein the first connecting element extends in a direction at least substantially perpendicular to the second surface.
