The dividing chamber holder (10) for a dough dividing machine, comprises a dividing chamber defining a dividing chamber volume with a first measuring piston (32) guided in it, where the measuring piston is drivable for dividing-off the dough volumes, and a sleeve insertable into the dividing chamber, arrestable into the dividing chamber and reducing the dividing chamber volumes with a second measuring piston guided in it. The first measuring piston and the sleeve are provided as separate components that are interchangeable against each other. The dividing chamber holder (10) for a dough dividing machine, comprises a dividing chamber defining a dividing chamber volume with a first measuring piston (32) guided in it, where the measuring piston is drivable for dividing-off the dough volumes, and a sleeve insertable into the dividing chamber, arrestable into the dividing chamber and reducing the dividing chamber volumes with a second measuring piston guided in it. The first measuring piston and the sleeve are provided as separate components that are interchangeable against each other. The first measuring piston comprises a front measuring piston area with a first circular cross-section having a first measuring piston diameter and a center measuring piston area with a second circular cross-section having a second measuring piston diameter. The second cross-section is smaller than the first cross-section or the center measuring piston area comprises a cross-section with a polygonal, where the cross-section has a contour section, which lies on a circular arc with the first measuring piston diameter. A measuring piston groove extending in a longitudinal direction of the sleeve is formed at the outer circumference of the first measuring piston and/or a sleeve groove extending in a longitudinal direction of the sleeve is formed at the outer circumference of the sleeve and/or a measuring piston flange is formed at the free end of the first measuring piston, where a tool engagement opening is provided at the measuring piston flange and/or a sleeve flange is formed at the free end of the sleeve, where a tool engagement opening is provided at the sleeve flange. A sleeve insert part, which is made of metal, defines a sleeve locking opening provided with an inclined surface and is present in a corresponding sleeve insert opening provided at the outer circumference of the sleeve, is used for arresting the sleeve in the dividing chamber. The second measuring piston guided into the sleeve has a guiding recess at the outer circumference, where the guiding recess extends itself in the longitudinal direction of the measuring piston and receives and guides a locking pin extending transverse to the longitudinal direction and assigned to the sleeve. The guiding recess is formed by a center area of the second measuring piston with polygonal cross-section, where the polygonal cross-section defines a clear positioning of the second measuring piston within the sleeve together with the locking pin. The locking pin is incorporated into a reception hole extending through the sleeve flange in a secant-like manner. The locking pin is assigned by a threaded pin, which is incorporated into a threaded hole provided in the sleeve and extending transverse to the reception hole and engages into a peripheral groove in the area of the free ends of the locking pin. The dividing chamber holder has a barrier piston, where a barrier piston groove extends in the longitudinal direction of the barrier piston and is formed at the outer circumference of the barrier piston. A barrier piston flange is formed at the free ends of the barrier piston, where a tool engagement opening is provided at the barrier piston flange. A barrier piston insert part, which is made of metal, defines a barrier piston locking opening provided with an inclined surface and is present in a corresponding barrier piston insert opening provided at the outer circumference of the barrier piston, is used for arresting the barrier piston in the dividing chamber. The second measuring piston guided into the sleeve is produced from polyoxymethylene and/or the sleeve consists of polyethylene terephthalate. The second measuring piston guided into the sleeve is produced from polyoxymethylene and/or the sleeve consists of polyethylene terephthalate. The front surface of the first measuring piston, the sleeve, the second measuring piston and/or barrier piston are shape-adapted to the immediately adjacent areas of the outer contour of the dividing chamber holder, where the difference between the outer radius and the inner radius of the sleeve is 7.5-25 mm. |
