Abstract

Systems and methods are provided for scraping tools for edging composite parts. One embodiment is an apparatus that includes a scraping tool. The scraping tool includes a base member, a first wall upwardly extending from a first side of the base member, a second wall upwardly extending from a second side of the base member, and a channel defined by the base member, the first wall, and the second wall. The scraping tool further includes a first blade mount within the channel that is fixed to the first wall, and a second blade mount within the channel that is fixed to the second wall. The first blade mount secures a blade oriented oblique to the base member, and the second blade mount secures a blade oriented oblique to the base member.

First claim

The invention claimed is:

1. An apparatus comprising:
a scraping tool comprising:
a base member;
a first wall upwardly extending from a first side of the base member;
a second wall upwardly extending from a second side of the base member;
a channel defined by the base member, an inner surface of the first wall, and an inner surface of the second wall;
a first blade mount within the channel that abuts the inner surface of the first wall and is disposed wholly within the channel; and
a second blade mount within the channel that abuts the inner surface of the second wall and is disposed wholly within the channel,
wherein the first blade mount engages a stationary blade having a first cutting edge oriented oblique to the base member such that a line coincident with the first cutting edge intersects the first wall and the base member, and the second blade mount engages a stationary blade having a second cutting edge oriented oblique to the base member such that a line coincident with the second cutting edge intersects the second wall and the base member, and wherein each of the first blade mount and the second blade mount includes an orifice for receiving a fastener that removably secures the stationary blade in place, wherein the orifice defines a central axis oriented oblique to the base member, and to one of the first wall and the second wall.

2. The apparatus of claim 1 further comprising:
a first guide within the channel that projects laterally from the first wall towards the second wall; and
a second guide within the channel that projects laterally from the second wall towards the first wall,
wherein a gap between the first guide and the second guide is located above the first blade mount and the second blade mount.

3. The apparatus of claim 2 wherein:
each of the first guide and the second guide includes a curved forward edge.

4. The apparatus of claim 2 wherein:
the scraping tool further comprises:
a first piece that includes the first wall, the first blade mount, and a first segment of the base member;
a second piece that includes the second wall, the second blade mount, and a second segment of the base member; and
an adjustable brace that structurally unites the first piece and the second piece.

5. The apparatus of claim 1 wherein:
the scraping tool further comprises a rail that protrudes from the base member into the channel, extends from a front end to a back end of the base member, and is located between the blade mounts.

6. The apparatus of claim 1 wherein:
the scraping tool comprises:
multiple first blade mounts along the first wall;
multiple second blade mounts along the second wall; and
corresponding stationary blades secured to the blade mounts along the first wall and the second wall.

7. The apparatus of claim 6 wherein:
each of the blades is removably attached to a corresponding blade mount.

8. The apparatus of claim 6 wherein:
each of the blades lays flat against a corresponding blade mount.

9. The apparatus of claim 6 wherein:
blades secured to blade mounts along the first wall are oriented in a first direction; and
blades secured to blade mounts along the second wall are oriented in a second direction.

10. The apparatus of claim 1 further comprising:
cavities that each communicate with a corresponding orifice, and are dimensioned to receive a nut for securing a fastener in place.

11. The apparatus of claim 1 wherein:
an exterior volume surrounds the scraping tool; and
the scraping tool further comprises a groove that contacts the exterior volume.

12. The apparatus of claim 1 further comprising:
a handle attached to the base member.

13. The apparatus of claim 1 further comprising:
deflectors that protrude upward from the base member and extend from a front end to a back end of the base member to form a debris channel.

14. The apparatus of claim 13 wherein:
the first blade mount and the second blade mount interrupt the deflectors as the deflectors continue along a length of the base member.

15. The apparatus of claim 14 wherein:
the deflectors each comprise a convex arc extending from the base member.

16. The apparatus of claim 14 wherein:
a forward portion of each deflector is semi hemispherical.

17. An apparatus comprising:
a frame defining a C-shaped channel comprising two walls and a base member; and
stationary blades within the C-shaped channel that are secured along and obliquely oriented to the walls of the C-shaped channel such that for each cutting edge of each of the stationary blades, a line coincident with the cutting edge intersects a wall of the frame and the base member of the frame,
wherein the stationary blades positioned along a respective wall have a same orientation, each of the stationary blades is obliquely oriented with respect to a corresponding wall, the stationary blades positioned along different walls extend for less than half of a width of the C-shaped channel, and each of the stationary blades slopes downwards from a corresponding wall towards the base member,
wherein the stationary blades are each removably secured to a blade mount proximate to an orifice in the blade mount that is dimensioned to receive a fastener that secures the stationary blade in place, wherein the orifice defines a central axis oriented oblique to the two walls and the base member; and
wherein the frame comprises the respective blade mounts.

18. The apparatus of claim 17 further comprising: a guide that extends laterally from each of the respective walls, wherein a gap between the guides is located above the stationary blades.

19. The apparatus of claim 18 wherein:
each of the guides includes a curved forward edge.

20. An apparatus comprising:
a frame;
a first set of stationary blades mounted to the frame that are arranged in series along a length of a first side of the frame such that for each cutting edge of each of the stationary blades in the first set, a line coincident with the cutting edge intersects the first side of the frame and a base of the frame; and
a second set of stationary blades mounted to the frame that are arranged in series along the length of a second side of the frame such that for each cutting edge of each of the stationary blades of the second set, a line coincident with the cutting edge intersects the second side of the frame and the base of the frame,
wherein the second side of the frame faces the first side of the frame,
wherein the stationary blades in the first set have the same orientation that is angled towards an interior portion of a channel defined by the frame, and the stationary blades in the second set have an orientation that is mirrored with respect to the stationary blades in the first set,
wherein the stationary blades are each removably secured to a respective blade mount proximate to an orifice in the blade mount that is dimensioned to receive a fastener that secures the stationary blade in place, wherein the orifice defines a central axis oriented oblique to one of the first side and the second side of the frame, and to the base of the frame; and
wherein the frame comprises the respective blade mounts.
