Tool with different effective areas
The invention relates to a tool for processing a workpiece in particular for pressing, holding and/or cutting a pipe, having a first pair of jaws which has a first upper jaw and a first lower jaw, having a first effective area formed between the front ends of the first jaws, having a first inlet contour formed between the rear ends of the first jaws and having a holding device which movably accommodates the first jaws independent of one another, wherein the first jaws can be pivoted between an open position and a closed position. The present invention is based on the technical problem of specifying a tool, by means of which in one process at least one first and one second effect can be assigned to the tool independently from one another in time.
1. A tool for processing a workpiece, comprising
a first pair of jaws, having a first front ends and a first rear ends, which has a first upper jaw and a first lower jaw,
a first effective area formed between the first front ends of the first jaws,
a first inlet contour formed between the first rear ends of the first jaws and
a holding device which movably accommodates the first jaws independent of one another,
wherein the first jaws can be pivoted between an open position and a closed position,
wherein a second pair of jaws, having a second front ends and a second rear ends, is provided which has a second upper jaw and a second lower jaw,
wherein a second effective area is formed between the second front ends of the second jaws,
wherein a second inlet contour is formed between the second rear ends of the second jaws,
wherein the holding device movably accommodates the second jaws independent of one another and independent of the first jaws,
wherein the second jaws can be pivoted between an open position and a closed position, and
wherein the first inlet contour and the second inlet contour are formed differently.
2. The tool according to claim 1 , wherein a first effective contour and a second effective contour are formed differently.
3. The tool according to claim 1 , wherein each pairs of jaws are arranged offset relative to each other, and each pairs of jaws are configured to perform effects on areas along a workpiece to be inserted.
4. The tool according to claim 1 , wherein the holding device has at least two pins, wherein a first pin is a common pivot pin for the upper jaws and a second pin is a common pivot pin for the lower jaws.
5. The tool according to claim 1 , wherein at least one pair of jaws is integrally formed with an effective contour, which forms one of the first effective area and the second effective area.
6. The tool according to claim 1 ,
wherein a third pair of jaws, having a third front ends and a third rear ends, is provided which has a third upper jaw and a third lower jaw,
wherein a third effective area is formed between the third front ends of the third jaws,
wherein a third inlet contour is formed between the third rear ends of the third jaws,
wherein the holding device movably accommodates the third jaws independent of one another and independent of the first jaws and the second jaws,
wherein the third jaws can be pivoted between an open position and a closed position, and
wherein the third inlet contour is formed differently from the first inlet contour or from the second inlet contour, and
wherein the second pair of jaws is arranged between the first pair of jaws and the third pair of jaws.
7. The tool according to claim 6 , wherein each case the first upper jaw and third upper jaw and first lower jaw and third lower jaw are fixedly connected to one another via connecting elements.
8. The tool according to claim 7 , wherein the first pair of jaws and the third pair of jaws have the same inlet contour.
9. The tool according to claim 6 , wherein at least four tool elements are provided, in that in each case a front tool element and a rear tool element are in contact with the second upper jaw and in each case a front tool element and a rear tool element are in contact with the second lower jaw, and in that the tool elements take part in the movement of the second jaws.
10. The tool according to claim 9 , wherein the first jaws and/or third jaws have holders for the tool elements, wherein the tool elements can move relative to the jaws and relative to one another.
11. The tool according to claim 9 , wherein at least one second jaw has at least one for each tool element.
12. The tool according to claim 11 , wherein the bumps of the second jaws apply a force to the tool elements essentially at the same time.
13. The tool according to claim 1 , wherein at least one effective contour is a pressing contour.
14. The tool according to claim 1 , wherein at least one effective contour is a holding contour and at least one effective contour is a cutting contour, wherein each of the at least one effective contours form one of the first effective area and the second effective area.
15. The tool according to claim 1 , wherein at least two effective contours are identical.
