Apparatus and method for automatic swaging of tubes
View Patent ↗An automatic swaging machine including a conveyor system for moving tubes into position for swaging a clamping apparatus to secure the tubes adjacent a swaging station to receive a swaging tool releasing a clamping apparatus during the swaging operation, reclamping the tools after swaging to remove the swaging tool from the ends of the tubes and moving the tubes with the conveyor system into a receiving receptacle.
1. An automatic swaging machine for swaging the ends of tubes comprising:
a bin for receiving a supply of unswaged tubes;
means for conveying a tube from said receiving bin to a swaging station;
a swaging tool;
means for gripping said tube for positioning of said swaging tool into engagement with said tube for swaging thereof;
means for releasing said means for gripping during execution of said swaying operation;
means for regripping said tube subsequent to execution of said swaging operation to allow disengagement of said swaging tool from said tube; and
means for disposition of a swaged tube into a collection bin.
2. An automatic swaging tool as defined in claim 1 , which further includes means for aligning said tube with said swaging tool.
3. An automatic swaging tool as defined in claim 2 , wherein said means for aligning includes a member defining a recess for receiving said tube.
4. An automatic swaging tool as defined in claim 3 , wherein said means for gripping includes a clamp disposed, opposed said recess defining member, and means for moving said clamp toward and away from said tube.
5. An automatic swaging tool as defined in claim 3 wherein said member defining a recess is a support block having a pair of V shaped openings therein.
6. An automatic swaging tool as defined in claim 4 wherein said clamp is a block having a pair of V shaped openings therein.
7. An automatic swaging tool as defined in claim 1 wherein said means for gripping further includes a V support block disposed adjacent said swaging tool for receiving said tube in alignment with said swaging tool and a V clamping block disposed opposed said V support block and means for relatively moving said V clamping block and said V support block to clamp said tube there between.
8. An automatic swaging tool at defined in claim 7 wherein said means for relatively moving includes a cylinder and piston rod, said V clamping block being affixed to said piston rod.
9. An automatic swaging tool as defined in claim 1 wherein said means for conveying is a conveyor system having a plurality of upwardly extending arms for engaging a tube.
10. An automatic swaging tool as defined in claim 9 wherein said swaging tool includes two spaced apart swaging machines and said upstanding arms are spaced apart by a distance equal to the distance between the two swaging machines.
11. The method of swaging a tube comprising:
providing a swaging tool;
moving a tube to be swaged into position adjacent said swaging tool;
gripping said tube to preclude longitudinal movement thereof;
engaging said swaging tool with said tube;
releasing said tube;
swaging said tube;
regripping said tube;
disengaging said swaging tool from said tube; and
moving said swaged tube away from said swaging tool.
12. The method of swaging a tube as defined in claim 11 which further includes aligning said tube with said swaging tool before gripping said tube.
13. The method of swaging a tube as defined in claim 12 which further includes moving said swaging tool into engagement with said tube before swaging said tube.
14. The method of swaging a tube as defined in claim 13 which further includes moving said swaging tool away from said tube after swaging said tube.
