Abstract
Deburring tools for removing a burr from a piece of sheet metal like a skate iron. The deburring tool is provided with two clamping jaws, between which an edge of the sheet metal can be pulled. The clamping jaws are resiliently mounted one to the other and at least one of the clamping jaws consists of a cutter.
Description
Debarring tool The invention relates to a debarring tool for removing a burr of a piece of sheet metal, provided with at least one cutter, which is operationally moved alongside an edge of the piece of sheet metal. Arrangements of this type, normally shaped as a hand tool, are well known in the art.
The problem with these known debarring tools is that they don't give a reproducible result and that they often damage the piece of sheet metal.
The present invention enables even an unskilled person to deburr a piece of sheet metal and in particular a skate iron. For skate irons often a small grinding stone is used for removing a burr, for example after the skates have been ground, but this is time consuming and tricky. The inventive tool is characterized in that the debarring tool comprises a clamp, provided with two clamping jaws, of which at least one clamping jaw is the cutter. It is sufficient then to pull for example a skate iron between the clamping jaws in a single continuous movement in order to deburr at least one side of it.
A favourable embodiment of the debarring tool, which makes it even more convenient debarring a plate, is characterized in that spring means are provided, for clamping the two jaws together with a predefined force.
An embodiment of the inventive debarring tool which can be manufactured cheap, is characterized in that the spring means consist of two stacked sheets made of a resilient material, like plastic, which are connected on a first edge one to the other and on which the clamping jaws are mounted on a second edge, opposite to the first edge.

A favourable embodiment of the debarring tool, which makes it even more convenient debarring a plate, is characterized in that spring means are provided, for clamping the two jaws together with a predefined force.
An embodiment of the inventive debarring tool which can be manufactured cheap, is characterized in that the spring means consist of two stacked sheets made of a resilient material, like plastic, which are connected on a first edge one to the other and on which the clamping jaws are mounted on a second edge, opposite to the first edge.
A very flat embodiment of the invention, which can be stored conveniently, is characterized in that the cutter comprises a plate made of a hard material, like steel or ceramic, mounted near the second edge.
An alternative embodiment of the inventive deburring tool, with which two sides of the piece of sheet metal can be deburred simultaneously, is characterized in that the clamp consists of a mounting plate, on an edge of which two cutters are mounted, facing each other.
A favourable embodiment in which the spring means have been realised simple and effective, is characterized in that the mounting plate and each cutter are provided with a mounting hole, through which a mounting pin is fed, and that the spring means consist of two spring washers, mounted on both sides of the cutters. The mounting pin may consist here for example of a screwed or riveted connection.
Another favourable embodiment, which gives the best results for sheet metal with a given thickness, is characterized in that the mounting plate has at least substantially the same thickness as the sheet metal.
Another favourable embodiment of the inventive deburring tool, which guarantees a very good guidance of the sheet metal plate, is characterized in that the mounting plate consists of a bottom of two recesses, made on both sides of a thicker guiding plate and that the guiding plate is provided wit a channel, through which the sheet metal can be fed. The guiding plate can be made in one single piece, for example as an injection-moulded part, for example made of plastic.

The invention will now be further explained with a reference to the figures, in which:
Fig. 1A represents in side view first possible a embodiment of a deburring tool according to the invention;
Fig. 1B represents this embodimentin front view;
Fig. 2A represents in side view second possible a embodiment of a deburring tool according to the invention;

Fig. 4 Brepresents this embodiment in cross section.
Fig. 1A represents in side view a first possible embodiment of a deburring tool according to the invention, provided with a first clamping jaw 1 and a second clamping jaw 2, between which a plate 3 can be pulled which has to be deburred. Jaw 1 and jaw 2 are separated by a spacer 4 in such a manner that plate 3 neatly fits between clamps 1,2.
Jaw 1 may be given a slight bending, in which case plate 3 is pushed actively against jaw 2. At least one side of jaw 2 is provided with a sharp edge 5 that will remove a blurr from plate 3, if present, when it is pulled through. Jaw 1, spacer 4 and jaw 2 are kept together by rivets or screwed joints 6.
Fig. 1B represents this embodiment in front view, with jaw 1, jaw 2 having sharp edges 5a,5b, spacer 4 and two rivets 6a, 6b .
Fig. 2A represents in side view a second possible embodiment of a debarring tool according to the invention, provided with a plate-shaped first clamping jaw 7 and a second clamping jaw 8 that has been mounted to a plate 9.
First clamping jaw 7 and plate 9 together are clamped in a U-shaped profile 10 and fixed with two rivets or screwed joints 11. They may be made of a resilient material, like metal or plastic. In order to remove a burr from a plate 12, the plate can be pulled between first clamping jaw 7 and second clamping jaw 8, in the process of which a sharp edge 13 cuts off a burr that might be present. In this embodiment, second clamping jaw 8 is a circular plate made of tool steel or a ceramic material, which is mounted to plate 9 with the aid of a screw 14. An advantage is that the plate can be rotated if one part of sharp edge 13 has become blunt. Another advantage of the embodiment shown here is also that plates with different or uneven thickness can be debarred, because of the resilient behaviour of first clamping jaw 7 and/or plate 9.
Fig. 2B represents this embodiment in front view, with first clamping jaw 7, plate 9, U-shaped profile 10, rivets 11a, 11b and second clamping jaw 8 which is mounted to plate 9 with the aid of screw 14.
Fig. 3A represents in side view a third possible embodiment of a debarring tool according to the invention, with a plate-shaped first clamping jaw 15 and a second clamping jaw 16 that has been mounted to a plate 17. In this embodiment, first clamping jaw 15 is provided with a projecting part, which in a state of rest at least substantially contacts second clamping jaw 16. First 5 clamping jaw 15 and plate 17 together are clamped in a U-shaped profile 18 and fixed with two rivets or screwed joints 19. They may be made of a resilient material, like metal or plastic. In order to remove a burr from a plate 20, the plate can be pulled between first clamping jaw 15 and second clamping jaw 21, in the process of which a sharp edge 21 cuts off a burr that might be present. In this embodiment, second clamping jaw 16 is a rectangular plate made of tool steel or a ceramic material, which is mounted to plate 17 with the aid of a screw 22. An advantage is that sharp edge 21 always makes a near optimal cutting angle, while the plate may be rotated over ninety degrees if sharp edge 21 has become blunt. An additional advantage of the embodiment shown here is that even very thin plates with different or uneven thicknesses can be deburred, because of the resilient behaviour of first clamping jaw 15 and/or plate 17 and the upright part of first clamping jaw 15.
Fig. 3B represents this embodiment in front view, with first clamping jaw 15, plate 17, U-shaped profile 18, rivets l9a,l9b and second clamping jaw 16 which is mounted to plate 17 with the aid of screw 22. The embodiment shown here is particularly well suited for removing a burr from a skate iron, for example when the skate has been ground, simply by pulling it a few times through the deburring tool.
Fig. 4A represents in front view a possible embodiment of a two-sided deburring tool, consisting of a guiding plate 23 in which recesses 24a,24b have been made on both sides, in which two plates 25a,25b made of tool steel or a ceramic material are placed, between which the sheet metal to be deburred can be pulled. The thickness of the wall between the recesses 24a,24b is chosen to be the same as the thickness of the sheet metal that has to be deburred and it forms a mounting plate for the plates 25a,25b. In order to let pass the sheet metal, a channel 26 is made in a longitudinal direction in guiding plate 23, having a width, which corresponds with the thickness of the sheet metal.
Plates 25a,25b are mounted to the wall between the recesses 24a,24b with the aid of a rivet 27. In order to provide some resilience, spring washers 28a,28b have been placed between the heads of rivet 21 and plates 25a,25b.
Fig. 4B represents this embodiment in cross section, guiding plate 23, in which recesses 24a,24b are made, in which two plated 25a,25b made of tool steel or a ceramic material are placed, between which the sheet metal to be deburred may be pulled. The unit is kept together with a rivet 27, while spring washers 28a,28b provide for some resilience.
