Abstract

An assembly in accordance with some example embodiments includes a support structure, first and second plates coupled to the support structure, and a shearing apparatus operable to cut a workpiece between ends of the workpiece. The first plate engages and guides a first end of a workpiece, and the second plate engages and guides a second end of the workpiece. The shearing apparatus includes a stationary die and a movable die and coupled to the support structure between the first plate and the second plate.

First claim

What is claimed is:

1. An assembly configured to shear a workpiece having first and second ends, comprising:
a support structure;
a first beam slidably attached to the support structure and a first workpiece engaging plate coupled to the first beam, the first workpiece engaging plate having a cutout therein in which the workpiece is configured to seat; and
a second beam slidably attached to the support structure and a first stop plate coupled to the second beam and against which the workpiece is configured to engage; and
a shearing apparatus operable to cut the workpiece between the first and second ends thereof, the shearing apparatus including a stationary die and a movable die, the shearing apparatus being coupled to the support structure between the first workpiece engaging plate and the first stop plate and at a position spaced from the first workpiece engaging plate and the first stop plate.

2. The assembly of claim 1 , wherein the first workpiece engaging plate is configured to engage an end of the support structure.

3. The assembly of claim 1 , further comprising a lock engageable with the first beam and the support structure to prevent movement of the first beam relative to the support structure.

4. The assembly of claim 1 , further comprising a measuring tape on an upper surface of the second beam.

5. The assembly of claim 4 , wherein the support structure includes a tray to which the shearing apparatus, the first beam and the second beam are coupled, wherein the second beam is attached to a lower surface of the tray, and further including a measuring tape on the upper surface of the tray between the shearing apparatus and the first stop plate.

6. The assembly of claim 5 , wherein the support structure further includes a second tray, a plurality of legs coupling the first defined tray to the second tray.

7. The assembly of claim 4 , wherein the support structure includes a tray to which the shearing apparatus, the first beam and the second beam are coupled, the tray having a window therethrough which aligns with a portion of the measuring tape which is under the window.

8. The assembly of claim 1 , further comprising a first lock engageable with the first beam and the support structure to prevent movement of the first beam relative to the support structure, and a second lock engageable with the second beam and the support structure to prevent movement of the second beam relative to the support structure.

9. The assembly of claim 1 , wherein the shearing apparatus has an opening therethrough through which the workpiece is configured to extend, the opening aligning with the cutout.

10. The assembly of claim 1 , wherein the support structure includes an upper tray, a lower tray, a plurality of legs coupling the upper tray to the lower tray, wherein the shearing apparatus is coupled to the upper tray.

11. The assembly of claim 10 , wherein the support structure further includes a plurality of wheels coupled to the lower tray.

12. The assembly of claim 1 , wherein the support structure comprises a movable cart having wheels.

13. The assembly of claim 1 , wherein the shearing apparatus includes
a housing forming a stationary die pocket in which the stationary die is removably seated and a movable die pocket in which the movable die is removably seated, the pockets being aligned with the first workpiece engaging plate and the first stop plate.

14. The assembly of claim 1 , the first stop plate aligns with the cutout of the first workpiece engaging plate.

15. An assembly configured to shear a workpiece having first and second ends, comprising:
a support structure;
a first beam slidably attached to the support structure, a first workpiece engaging plate affixed to an end of the first beam, and a second workpiece engaging plate coupled to the first workpiece engaging plate, wherein a position of an upper end of the second workpiece engaging plate can be moved relative to a position of an upper end of the first workpiece engaging plate, the second workpiece engaging plate engaging the workpiece and configured to guide the workpiece;
a stop plate coupled to the support structure, the stop plate engaging the second end of the workpiece; and
a shearing apparatus operable to cut the workpiece between the ends, the shearing apparatus including a stationary die and a movable die, the shearing apparatus being coupled to the support structure between the coupled first and second workpiece plates and the stop plate.

16. The assembly of claim 15 , wherein the first workpiece engaging plate has a cutout therein in which the workpiece can seat, and the second workpiece engaging plate has a cutout therein in which the workpiece can seat.

17. The assembly of claim 16 , wherein the cutout in the first workpiece engaging plate has a first shape, and the cutout in the second workpiece engaging plate has a second shape, the first and second shapes being different.

18. An assembly configured to shear a workpiece having first and second ends, comprising:
a support structure;
a first beam slidably attached to the support structure, a first workpiece engaging plate affixed to an end of the first beam, and a second workpiece engaging plate coupled to the first workpiece engaging plate, wherein a position of an upper end of the second workpiece engaging plate can be moved relative to a position of an upper end of the first workpiece engaging plate;
a second beam slidably attached to the support structure, a first stop plate affixed to an end of the second beam, and a second stop plate coupled to the first stop plate, wherein a position of an upper end of the second stop plate can be moved relative to a position of an upper end of the first stop plate; and
a shearing apparatus operable to cut the workpiece between the ends, the shearing apparatus including a stationary die and a movable die, the shearing apparatus being coupled to the support structure between the coupled first and second workpiece engaging plates and the coupled first and second stop plates.
