Articulating band saw and method
View Patent ↗An articulating band saw apparatus provides a frame that includes a vertically extending section having upper and lower end portions. An elevator moves between the upper and lower end portions of the frame. A first hydraulic actuator is supported on the elevator for movement therewith. A first arm provides arm end portions, the first arm supported by the first hydraulic actuator. An end of the first arm supporting a second hydraulic actuator that is spaced away from the first hydraulic actuator. The second hydraulic actuator supports a second arm. An endless band type saw is mounted on the free end of the second arm generally opposite the second actuator. The band saw is movable by articulation of the first and second actuators and resulting movement of the first and second arms. In one embodiment, the band saw is a diamond wire saw.
1. An articulating band saw apparatus, comprising:
a) a frame that includes a vertically extending section having upper and lower end portions;
b) an elevator that moves between the upper and lower end portions;
c) a first powered actuator supported on the elevator for movement therewith;
d) a first arm having arm end portions, the first arm supported by the first hydraulic actuator;
e) a second powered actuator supported by the first arm at a position spaced away from the first powered actuator;
f) a second arm supported by the second powered actuator;
g) an endless band type saw mounted on the free end of the second arm spaced away from the second actuator, the band saw including a band saw frame and a cutting blade;
h) wherein the band saw is movable by articulation of the first and second actuators and resulting movement of the first and second arms.
2. The band saw apparatus of claim 1 , wherein the actuators are independently controllable with the control panel.
3. The band saw apparatus of claim 1 , wherein the elevator and actuators are remotely controlled from a remotely located control panel spaced away from the saw blade.
4. The band saw apparatus of claim 1 , wherein the band saw is movable horizontally and vertically by the actuators.
5. The band saw apparatus of claim 1 , wherein the saw blade can be positioned with the actuators at an angle relative to horizontal.
6. The band saw apparatus of claim 1 , wherein the saw blade is powered by a motor, and the band saw motor torque is maximized by applying up to two thousand five hundred (2,500) pounds per square inch of hydraulic pressure that is determined by the cutting feed rate.
7. The band saw apparatus of claim 1 , wherein the elevator travels between elevated and lowered positions upon a frame, and a hydraulic lift cylinder connects between the frame and the elevator.
8. The band saw apparatus of claim 7 , wherein the control panel has a pressure gauge for monitoring hydraulic pressure of the lift cylinder, a lift cylinder control valve that enables control of elevator position, and wherein a saw cutting rate can be controlled by operator monitoring of the pressure gauge and by operator control of the lift cylinder control valve.
9. The band saw apparatus of claim 1 , further comprising a fluid delivery flow line that enables transmission of cooling or lubrication fluid to the saw blade and target for freezing at least a portion of the target during a cut.
10. The band saw apparatus of claim 3 , further comprising a camera that enables viewing of the cutting blade and a monitor next to the control panel that enables the operator to view the cutting blade during cutting.
11. The band saw apparatus of claim 1 , wherein the saw blade is diamond wire, and comprising multiple roller guides on the band saw frame that support the diamond wire.
12. An articulating band saw apparatus, comprising:
a) a frame that includes a vertically extending section having upper and lower end portions;
b) an elevator that moves between the upper and lower end portions;
c) a powered articulating boom mounted on the elevator;
d) an endless band type saw mounted on the free end of the boom, the band saw including a band saw frame and a cutting blade; and
e) wherein the band saw is movable in a vertical plane, both vertically and horizontally by articulation of the boom.
13. The band saw apparatus of claim 12 , wherein the elevator and boom are remotely controlled from a remotely located control panel spaced away from the saw blade.
14. The band saw apparatus of claim 12 , wherein the band saw is movable horizontally and vertically by the boom.
15. The band saw apparatus of claim 1 , wherein the saw blade can be positioned with the boom at an angle relative to horizontal.
16. The band saw apparatus of claim 12 , wherein the elevator travels between elevated and lowered positions upon a frame, and a hydraulic lift cylinder connects between the frame and the elevator.
17. The band saw apparatus of claim 13 , wherein the control panel has a pressure gauge for monitoring hydraulic pressure of the lift cylinder, a lift cylinder control valve that enables control of elevator position, and wherein a saw cutting rate can be controlled by operator monitoring of the pressure gauge and by operator control of the lift cylinder control valve.
18. The band saw apparatus of claim 12 , further comprising a fluid delivery flow line that enables transmission of cooling or lubrication fluid to the saw blade and target for freezing at least a portion of the target during a cut.
19. The band saw apparatus of claim 18 , further comprising a camera that enables viewing of the cutting blade and a monitor next to the control panel that enables the operator to view the cutting blade during cutting.
20. The band saw apparatus of claim 1 , wherein the saw blade is diamond wire, and comprising multiple roller guides on the band saw frame that support the diamond wire.
