Small caliber crimping primer and primer feed
View Patent ↗As described above, this new primer feed system is both accurate and consistent. The primer feed station begins by loading primers from the vendor packaging into the vibratory feed bowl via the primer chute. The bowl has an adjustable height polycarbonate guard that is inside the main safety polycarbonate doors and exits above the machine. The bowl then orients the primers open side up and discharges them into the primer track. Crimping can be done with 3 or 5 pins or a complete radial crimp. Previous versions of the crimp station on these crimping machines involved a pin mounted to the upper ram and a lower pin actuated by the lower ram. It was difficult to time and adjust properly for a consistent crimp. This new approach to crimping has proved much more reliable, accurate and easier to adjust. It still utilizes an upper pin mounted to the upper moving ram assembly but the lower pin is fixed.
1. An ammunition primer feed and staking station comprising:
a primer track comprised of a first top end, which receives primers;
a second bottom end wherein said primers exit said primer track, wherein said primer track is slanted to allow gravity to assist said primers movement from said first end to said second end;
wherein said primers exit said second bottom end of said primer track and enter a slide cover track; and
wherein a horizontal primer slide comprises a recess to allow said primers to enter from said slide cover track.
2. The ammunition primer feed and staking station of claim 1 , wherein said primer track is slanted at an approximate 30-degree angle.
3. The ammunition primer feed and staking station of claim 1 , wherein said primer track is further comprised of an angle hole of said first top end of said primer track, wherein said angle hole directs air from said first top end to said second bottom end of said primer track to assist with said primers' movement from said first end to said second end.
4. The ammunition primer feed and staking station of claim 1 , wherein said primer track is further comprised of a camera mounted above said primer track.
5. The ammunition primer feed and staking station of claim 1 , wherein said primer track is further comprised of a spring-loaded push opening mounted below said primer track to allow individual primer removal.
6. The ammunition primer feed and staking station of claim 1 , wherein said slide cover track is at an approximate 15-degree angle to said horizontal primer slide.
7. The ammunition primer feed and staking station of claim 6 , wherein said slide cover track is further comprised of a plurality of slotted mounting holes, which allow movement of a slide cover.
8. The ammunition primer feed and staking station of claim 1 , wherein said recess is lower than said slide cover track.
9. The ammunition primer feed and staking station of claim 7 , wherein said primer slide is actuated by a pneumatic cylinder to extend said primer slide.
10. The ammunition primer feed and staking station of claim 9 , wherein said primer feed and initial staking station is further comprised of a push rod, which lifts a staking pin to push said primer into a case while said primer slide is extended.
