Method and device to produce a shaped sheet metal part

1. A method for producing a shaped sheet metal part, comprising following steps:

continuously feeding a sheet metal band unwound from a coil to a jet cutter;

cutting, by means of the jet cutter, a blank out of the sheet metal band moving at a constant speed, time required to cut the blank defining a cycle;

picking up the blank by means of a first transfer device operating in time with the cycle;

transferring the blank by means of the first transfer device to a shaping system operating in the time with the cycle; and

shaping the blank into the shaped sheet metal part by means of the shaping system.

2. The method described in claim 1 , further comprising steps of picking up at least one scrap piece shaped by cutting the blank and setting the at least one scrap piece on a first stacking place, by means of a second transfer device.

3. The method described in claim 1 , wherein in the step of transferring the blank to the shaping system, the blank is set, by the first transfer device, into a shaping device of the shaping system, or onto a transfer place.

4. The method described in claim 3 , further comprising steps of picking up the blank from the transfer place by means of a second transfer device working in the time with the cycle and setting into the shaping device of the shaping system, when the blank is set, by the first transfer device, onto the transfer place.

5. The method described in claim 4 , wherein if the jet cutter malfunctions, the blank is picked up, by the first transfer device or the second transfer device, from the transfer place located outside a transport path of the sheet metal band or the blank and transferred to the shaping system.

6. The method described in claim 1 , wherein if the shaping system malfunctions, the blank is set, by the first transfer device, onto a second stacking place located outside a transport path of the sheet metal band or the blank.

7. The method described in claim 1 , wherein the blank is transferred, by the first transfer device, to a transport device for transport through a furnace.

8. The method described in claim 1 , wherein the jet cutter that is used is a laser cutter with at least one laser cutting head that can be moved in a transport direction of the sheet metal band and a direction perpendicular to the transport direction.

9. The method described in claim 1 , wherein at least one press, at least one hot shaping press, or a hydroforming device is used as a shaping device.

10. A device to produce a shaped sheet metal part, comprising:

a feeding device for continuously feeding a sheet metal band unwound from a coil;

a jet cutter receiving the sheet metal band from the feeding device to cut a blank out of the sheet metal band moving at a constant speed, time required to cut the blank defining a cycle;

a first transfer device working in time with the cycle to pick up the blank and transfer the blank; and

a shaping system receiving the blank from the first transfer device and working in time with the cycle to shape the blank into the shaped sheet metal part,

wherein the feeding device continuously feeds the sheet metal band unwound from the coil to the jet cutter,

the jet cutter cuts the blank out of the sheet metal band moving at the constant speed,

the first transfer device working in time with the cycle picks the blank and transfers the blank to the shaping system working in time with the cycle, and

the shaping system shapes the blank into the shaped sheet metal part.

11. The device described in claim 10 , wherein the feeding device comprises a roller straightening machine.

12. The device described in claim 10 , further comprising a second transfer device to pick up a scrap piece formed by cutting the blank and to set the scrap piece on a first stacking place.

13. The device described in claim 10 , wherein the blank can be set, by the first transfer device, into a shaping device of the shaping system, or onto a transfer place.

14. The device described in claim 13 , further comprising a second transfer device working in the time with the cycle to pick up the blank from the transfer place and set the blank into the shaping device of the shaping system, when the blank is set, by the first transfer device, onto the transfer place.

15. The device described in claim 14 , further comprising a controller designed so that if the jet cutter malfunctions, the blank is picked up, by the first transfer device or the second transfer device, from the transfer place located outside a transport path of the sheet metal band or the blank and transferred to the shaping system.

16. The device described in claim 10 , further comprising a controller provided so that if the shaping system malfunctions, the blank is set, by the first transfer device, onto a second stacking place located outside a transport path of the sheet metal band or the blank.

17. The device described in claim 10 , wherein a furnace and a transport device to transport the blank into the furnace are provided.

18. The device described in claim 10 , wherein the jet cutter comprises a laser cutter with at least one laser cutting head that can be moved in a transport direction of the sheet metal band and a direction perpendicular to the transport direction.
