Abstract

A crimping tool comprising a frame, a die wheel rotatably connected to the frame by a pivot pin, a positioning system for detent locating the die wheel at predetermined rotational positions on the frame, and a cooperating die stationarily connected to the frame. The cooperating die has projections on its lateral sides which form downward and rearward facing support surfaces that rest against edges of the frame.

Claims

1. In a crimping tool comprising a frame having first and second jaws, and a first die connected to the frame at one of the jaws, wherein the improvement comprises:

a cooperating die mounted to the frame opposite the first die, wherein the cooperating die comprises a bottom section with a mounting hole, a top section with a crimping surface, and two laterally extending support sections extending from a same first lateral side of the cooperating die, wherein a first one of the support sections comprises a first support surface which rests against a first edge of the frame and a second one of the support sections comprises a second support surface which rests against a different second edge of the frame, and wherein the first and second support surfaces are angled relative to each other.

2. A tool as in claim 1 wherein the cooperating die comprises a third laterally extending support section extending from a second opposite lateral side of the cooperating die.

3. A tool as in claim 1 wherein the the second support surface is located at a rear end of the first lateral side of the cooperating die.

4. A tool as in claim 3 wherein the cooperating die comprises a third laterally extending support section located at a rear end of a second lateral side of the cooperating die.

5. A tool as in claim 4 wherein the cooperating die comprises a fourth laterally extending support section extending from the second lateral side.

6. A tool as in claim 1 wherein a top surface of the first laterally extending support section is located below the crimping surface.

7. A tool as in claim 1 wherein the crimping surface has a general V-shaped recess.

8. A tool as in claim 7 wherein the first and second laterally extending support sections are spaced from each other on opposite sides of the general V-shaped recess.

9. A tool as in claim 8 wherein the top sides of the support sections are located below the crimping surface.

10. A tool as in claim 1 wherein the first die comprises a die wheel rotatably connected to the frame by a pivot pin, and the tool further comprises a positioning system for detent locating the die wheel at predetermined rotational positions on the frame, the positioning system having a ball and a spring biasing the ball towards the die wheel, the spring being mounted to the frame by only the pivot pin.

11. A tool as in claim 10 wherein the die wheel comprises at least five different size crimp areas and at least five ball receiving areas, each ball receiving area being located between center axes of two adjacent ones of the crimp areas.

12. A tool as in claim 1 wherein the first die comprises a die wheel rotatably connected to the frame by a pivot pin, and the tool further comprises a positioning system for detent locating the die wheel at predetermined rotational positions on the frame, the positioning system having a ball and a spring biasing the ball towards the die wheel, wherein the ball is located adjacent a rigid flat washer on the pivot pin, and wherein the rigid flat washer is biased by the spring against the ball.

13. A tool as in claim 12 wherein the spring is located between the rigid flat washer and a head of the pivot pin.

14. In a crimping tool comprising a frame with first and second jaws, and a first die connected to the frame, wherein the improvement comprising:

a cooperating die stationarily mounted to the frame opposite the first die, wherein the cooperating die comprises a bottom mounting section, a top section with a crimpring surface, and a lateral projection extending from a lateral side of the cooperating die, the projection having a downward facing support surface which rests against an edge of the frame facing the die wheel and a rearward facing support surface which rests against another edge of the frame.

15. A tool as in claim 14 wherein the bottom mounting section has a hole therethrough with a mounting pin located in the hole mounting the bottom mounting section between two plate sections of the frame.

16. A tool as in claim 14 wherein the cooperating die comprises another lateral projection extending from the first lateral side and having another downward facing support surface which contacts the frame.

17. A tool as in claim 16 wherein the cooperating die has a second lateral side which is a mirror image of the first lateral side.

18. A tool as in claim 16 wherein the crimping surface has a general V-shaped recess and wherein the lateral projections on the first lateral side are located spaced from each other proximate opposite front and rear ends of the general V-shaped recess.

19. A tool as in claim 14 wherein the cooperating die has another lateral projection extending from a second opposite lateral side of the cooperating die having another downwardly facing support surface and another rearward facing support surface.

20. A tool as in claim 18 wherein the V-shaped recess has a center axis which has an inclined angle relative to an axis perpendicular to facing surfaces of the first and second jaws.
