Abstract

The present disclosure relates to a system for forming a cartridge case, the system including a series of stages, each stage comprising a sequential location in the system, and each stage comprising a process step, wherein each process step is synchronized to occur within a substantially simultaneous stage interval, the stages including: an annealing stage, a head forming stage, and a taper stage. The present disclosure also relates to a method for manufacturing a cartridge case, the method including: receiving a single cartridge case at a time in a first direction into an annealing chamber through a first opening, passing an alternating current through an inductive coil for a certain time period to heat the cartridge case, releasing the cartridge case from the annealing chamber in the first direction through a second opening, and performing a forming step on the cartridge case.

Claims (26)

1. A system for forming a cartridge case comprising:

a series of modules, each module occupying a sequential location in the system, and each module performing a process step, wherein each process step is performed on a single cartridge case at a time and is synchronized to occur within a substantially simultaneous interval, the modules comprising

an annealing module configured to individually anneal each cartridge case,

a head forming module configured to individually form a head of each cartridge case, and

a taper module configured to individually form a tapered neck of each cartridge case: and

one or more conveyors configured to sequentially transfer each cartridge case through the series of modules and wherein each cartridge case is maintained with a controlled orientation within and between the series of modules by the one or more conveyors.

2. The system of claim 1 , wherein the distance traveled between modules is less than twelve feet.

3. The system of claim 1 , wherein the head forming module comprises a press actuated by a servo motor.

4. The system of claim 3 , wherein the press comprises a die nest and the cartridge case is seated in the die nest during press forming, and wherein the die nest is monitored by a load cell.

5. The system of claim 1 , wherein the simultaneous interval has a duration determined by the completion of one or more process steps.

6. The system of claim 1 , wherein at least one of the modules is configured to determine whether a cartridge case passes or fails a testing criterion.

7. The system of claim 6 , further comprising an output module configured to selectively output the cartridge case to one of:

a fail location;

a pass location; and

a quality control location.

8. The system of claim 1 , wherein the cartridge case is maintained with an open side down in the taper module.

9. The system of claim 1 , wherein the cartridge case is maintained with an open side down within and between the head forming module and the taper module.

10. The system of claim 1 , wherein at least one of the modules is configured to take a first picture of a cartridge case, rotate the cartridge case by about 90 degrees, and take a second picture of the cartridge case.

11. The system of claim 1 , wherein maintaining the cartridge case in a controlled orientation comprises controlling the orientation of the cartridge case regardless of whether the cartridge case remains in an identical orientation.

12. The system of claim 1 , wherein the series of modules further comprises an extractor groove forming module.

13. The system of claim 1 , wherein the annealing module comprises an inductive coil and a coil insert, the insert encompassing the sides of an annealing chamber.

14. The system of claim 13 , wherein the coil insert is constructed of a non-conductive or non-magnetic material.

15. The system of claim 13 , the annealing module further comprising a casing enclosing and supporting the inductive coil.

16. The system of claim 15 , wherein the casing is constructed of a non-conductive or non-magnetic material.

17. The system of claim 13 , wherein the annealing chamber comprises a first opening and a second opening, wherein a cartridge case is allowed to pass into the annealing chamber through the first opening and out of the annealing chamber through the second opening.

18. The system of claim 17 , further comprising a release mechanism at the second opening of the annealing chamber.
