Profile cutting tool
A profile cutting tool includes a base, a clamp mounted to the base configured to hold an elongate workpiece, a pivotable frame pivotally mounted to the base, and a workpiece cutting assembly mounted to the pivotable frame and comprising a cutter configured to cut the elongate workpiece held in the clamp. When the pivotable frame pivots with respect to the base, the cutter is configured to move along an arcuate profile cutting path having a first radius.
1 . A profile cutting tool comprising:
a base;
a clamp mounted to the base and configured to hold a workpiece such that the workpiece is elevated relative to the base;
a frame pivotably mounted to the base; and
a workpiece cutting assembly mounted to the frame and comprising a cutter configured to cut the workpiece,
wherein pivoting the frame relative to the base causes the cutter to follow an arcuate cutting path through the workpiece.
2 . The profile cutting tool according to claim 1 , wherein the workpiece cutting assembly is repositionable along the frame relative to a pivot axis of the frame.
3 . The profile cutting tool according to claim 2 , wherein the workpiece cutting assembly further comprises a lock mechanism configured to secure the workpiece cutting assembly in a position along the frame.
4 . The profile cutting tool according to claim 1 , wherein the frame comprises an upright portion and an arm that extends outward from the upright portion.
5 . The profile cutting tool according to claim 4 , wherein the arm is a first arm and the frame further comprises a second arm that extends outward from the upright portion.
6 . The profile cutting tool according to claim 5 , wherein the first arm defines a first slot that extends into a distal end of the first arm and the second arm defines a second slot that extends into a distal end of the second arm, the first slot and the second slot configured to receive a cutting blade of the cutter therein.
7 . The profile cutting tool according to claim 5 , wherein the frame is configured such that, as the cutter cuts the workpiece, the first arm moves above the workpiece and the second arm moves below the workpiece.
8 . The profile cutting tool according to claim 4 , wherein the first arm defines a slot that extends into a distal end of the arm, the slot configured to receive a cutting blade of the cutter therein.
9 . The profile cutting tool according to claim 1 , wherein the cutter is a reciprocal cutting blade.
10 . The profile cutting tool according to claim 1 , wherein the workpiece cutting assembly further comprises a motor operatively coupled to the cutter.
11 . The profile cutting tool according to claim 1 , further comprising:
a platform that is mounted to the base and positioned above the base,
wherein the clamp is mounted on the platform.
12 . The profile cutting tool according to claim 11 , wherein the frame includes an arm that extends outward relative to a pivot axis of the frame, the arm arranged to move between the platform and the base.
13 . The profile cutting tool according to claim 1 , wherein the clamp comprises a pivotable fence and a pivotable workpiece engagement plate configured to clamp the workpiece against the pivotable fence.
14 . The profile cutting tool according to claim 1 , wherein the workpiece cutting assembly further comprises at least one guide bracket that slidably couples the workpiece cutting assembly to the frame.
15 . The profile cutting tool according to claim 14 , wherein the frame comprises indicia corresponding to a plurality of predetermined positions for the at least one guide bracket, each of the plurality of predetermined positions corresponding to a different radius of the arcuate cutting path.
16 . The profile cutting tool according to claim 15 , wherein the indicia comprises a scale indicating the plurality of predetermined positions.
17 . A profile cutting tool according to claim 1 , wherein the base comprises an upright bracket and the frame is pivotably mounted to the upright bracket.
18 . The profile cutting tool according to claim 17 , wherein the upright bracket defines a pivot axis about which the frame pivots, the workpiece cutting assembly defines a blade axis along which the cutter cuts, and the blade axis and the pivot axis extend parallel to one another.
19 . A profile cutting tool comprising:
a base configured to hold a workpiece;
an upright bracket attached to the base;
a frame pivotably mounted to the upright bracket via an upper pivot pin and a lower pivot pin that are spaced apart from one another along a pivot axis of the frame;
a cutting blade carried by the frame; and
a motor configured to cause the cutting blade to move relative to the frame, wherein the frame and the cutting blade are configured to pivot relative to the base while the motor moves the cutting blade relative to the frame to make an arcuate cut in the workpiece.
20 . The profile cutting tool of claim 19 , wherein the base is configured to hold the workpiece such that the workpiece is elevated relative to the base.
