Abstract

A working head for a hydraulic power tool. The working head includes a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head is configured to receive a first moveable die comprising a first body length and a second die head is adapted to receive a second die comprising a second body length. At least one of the moveable die or the stationary die comprises an elongated die.

First claim

1 . A working head for a power tool operated by a user on a work piece, the working head comprising:
a moveable die configured to be received by a moveable die head; the moveable die having an alignment feature for alignment of a target location indicating a crimp or cut location of the work piece; the alignment feature configured to be a groove visible to the user from a top view to help achieve a desired crimp or a desired cut at the target location.

2 . The working head of claim 1 , wherein the alignment feature is a first alignment feature;
wherein the moveable die head includes a second alignment feature; and wherein when the moveable die head receives the moveable die, the first alignment feature aligns with the second alignment feature.

3 . The working head of claim 2 , wherein the moveable die head includes
a main body; an upper surface; a lower surface; and an end face that is situated at a distal end of the moveable die head, the end face vertically extending along the main body; and wherein the second alignment feature extends on the end face of the moveable die head.

4 . The working head of claim 3 , wherein the second alignment feature extends along the upper surface of the moveable die head.

5 . The working head of claim 2 , and further comprising:
a head frame; and a die head coupled to the head frame, the die head having a vertical face, and an inclined face; wherein the die head has a third alignment feature; and wherein the first alignment feature is aligned with the third alignment feature.

6 . The working head of claim 5 , wherein the third alignment feature extends along the inclined face.

7 . The working head of claim 6 , wherein the third alignment feature extends along the vertical face.

8 . The working head of claim 5 , wherein the head frame defines a guide surface;
wherein the guide surface includes a fourth alignment feature that extends along the guide surface; and wherein the moveable die head is situated above the guide surface.

9 . The working head of claim 8 , and further comprising a cylinder having a fourth alignment feature extending along a portion of the outer surface of the cylinder.

10 . The working head of claim 9 , wherein at least one of the first alignment feature, the second alignment feature, the third alignment feature, or the fourth alignment feature is at least one of colored, painted, laser etched, coated; or labeled with a sticker.

11 . The working head of claim 9 , wherein at least one of the first alignment feature, the second alignment feature, the third alignment feature, or the fourth alignment feature is a groove.

12 . The working head of claim 9 , wherein at least one of the first alignment feature, the second alignment feature, the third alignment feature, or the fourth alignment feature is a dashed line or a continuous line of constant width.

13 . The working head of claim 1 , wherein the moveable die defines a horizontal surface; and wherein the alignment feature extends along the horizontal surface.

14 . The working head of claim 1 , wherein the moveable die includes a notch;
wherein the moveable die head includes a lip; and wherein when the moveable die head receives the moveable die, the lip of the moveable die head retains the notch of the moveable die.

15 . A working head for a power tool operated by a user on a work piece, the working head comprising:
a moveable die configured to be received by a moveable die head; the moveable die having an alignment feature for alignment of a target location indicating a crimp or cut location of the work piece; the alignment feature extending in the direction of movement of the moveable die; the alignment feature being at least one of colored, painted, laser etched, coated, or labeled with a sticker.

16 . The working head of claim 15 , wherein the alignment feature is a first alignment feature;
wherein the moveable die head includes a second alignment feature; and wherein when the moveable die head receives the moveable die, the first alignment feature aligns with the second alignment feature.

17 . The working head of claim 16 , and further comprising:
a head frame; and a die head coupled to the head frame, the die head having a vertical face, and an inclined face; wherein the die head has a third alignment feature; wherein the first alignment feature is aligned with the third alignment feature; and wherein the third alignment feature extends along the inclined face.

18 . The working head of claim 15 , wherein the alignment feature is a dashed line or a continuous line of constant width.

19 . A working head for a power tool, the working head comprising:
a moveable die configured to be received by a moveable die head, the moveable die including
a die plate that vertically extends;
a first horizontal surface situated at a first end of the die plate, the first horizontal surface extending beyond a thickness of the die plate;
a second horizontal surface situated at a second end of the die plate, the second horizontal surface extending beyond the thickness of the die plate;
the die plate, the first horizontal surface, and the second horizontal surface collectively define an I-beam structure; and a distal end of the die plate, a distal end of the first horizontal surface, and a distal end of the second horizontal surface lying in the same plane.

20 . The working head of claim 19 , wherein the moveable die defines a curved body portion having a curved outer surface received by the moveable die head.
