Description

The invention relates to a device for machining a ridge of an edge of an elongated object, in particular a ski, by means of a ridge machining element.

Usual deburring tools consist, for example, of a plate-shaped grindstone, which is used after a grinding process, for example, to remove or break the burr formed by grinding. This process is usually carried out without precise control of the machining process, with rounded and uneven burr edges in the longitudinal direction, which can affect reproducibility and accuracy. It was also found that machining burrs in only one direction does not produce the desired end result.

In the U.S. 4,850,252 A an arrangement of two file elements is shown approximately at right angles, which are independently adjustable in angle. This causes the beveling or chamfering of the ski edge. Machining of an edge ridge within the meaning of the invention is not described in this document, however, since it shows a two-dimensional machining.

The object of the invention is to process the burr that occurs, for example, during edge grinding in a reproducible manner in such a way that, for example, it increases the edge sharpness in a controlled manner.

Another object of the invention is to precisely control the machining sequence of the burr machining process and to enable burr machining in two planes.

• eine Führungsfläche, auf der das längliche Objekt der Länge nach in einer Längsrichtung entlangführbar ist,
• ein erstes Gratbearbeitungselement mit einer ersten Gratbearbeitungsfläche, die in einem flachen Winkel oder fluchtend zur Führungsfläche orientiert ist,
• ein zweites Gratbearbeitungselement mit einer zweiten Gratbearbeitungsfläche, die in einem steilen Winkel oder in einem rechten Winkel zur Führungsfläche orientiert ist,
• wobei das längliche Objekt beim Bewegen entlang der Führungsfläche mit dem Grat seiner Kante zunächst auf die erste Gratbearbeitungsfläche und darauffolgend auf die zweite Gratbearbeitungsfläche auftrifft.

According to the invention this is achieved by

• a guide surface on which the elongated object can be guided lengthways in a longitudinal direction,
• a first burr processing element with a first burr processing surface which is oriented at a shallow angle or in alignment with the guide surface,
• a second burr processing element with a second burr processing surface which is oriented at a steep angle or at a right angle to the guide surface,
• the elongated object, when moving along the guide surface, with the ridge of its edge first impinging on the first ridge working surface and then on the second ridge working surface.

In this way, the burr to be machined is subjected to machining one after the other by the first and second burr machining elements, which are aligned at a steep angle including 90 ° to each other, the burr initially being processed when the device according to the invention passes through the first burr machining element is turned over in a first direction and then by the second burr machining element in a second direction. The burr is primarily processed and not the side edge and the pavement edge. The reproducible machining of the ridge achieved in this way results in a precisely defined, sharp edge of the elongated object, for example a ski, which results in advantageous properties when using the elongated object, for example when making turns with the so machined ski.

In a further embodiment of the invention it can be provided that the first burr processing element is designed in the form of a plate, and that a top surface of the plate is the first burr processing surface.

The plate-shaped design of the burr processing element enables the same to be easily manufactured and held, as well as a design that can be exposed to high forces, and also offers the possibility of quickly replacing the burr processing element.

In a comparable manner, the second burr processing element can be designed in the form of a plate, a top surface of the plate being the second burr processing surface.

A further embodiment of the invention can consist in that a first pivotable holder is provided for the first burr processing element, via which the first burr processing element can be adjusted in an angular range about a pivot axis parallel to the longitudinal direction, the angular range having an aligned orientation and a flat orientation Includes angle with respect to the guide surface.

In this way, the angle at which the first burr processing element or the first burr processing surface is tilted relative to the guide surface can be adjusted as desired in the angular range in order to process the burr to be processed by the first burr processing element in a specific angular orientation of the same with respect to the burr in order to align it accordingly in a given direction.

In a preferred manner, the adjustable angular range of the first burr machining element can encompass an angle of 0 ° to 1.5 °.

According to a further embodiment of the invention, a second pivotable holder can be provided for the second burr processing element, via which the second burr processing element can be adjusted in an angular range about a pivot axis parallel to the longitudinal direction, the angular range having a perpendicular orientation and an orientation at a steep angle with respect to the Includes guide surface.

The second pivotable holder is used to set an angle at which the second burr processing element can be tilted relative to an alignment at right angles to the guide surface in order to vary the action of the second burr processing element on the burr of the edge to be processed accordingly.

The adjustable angular range of the second burr machining element can preferably include an angle of 84 ° to 90 °.

The angle adjustment range of the first and the second pivotable holder can be adjusted independently of one another.

A further embodiment of the invention can consist in the fact that the first burr processing element and the second burr processing element are made of different materials such as Ceramic, diamond, various stones, e.g. Arkansas, hardwood and hard metals are made.

In addition, however, other suitable materials can also be used. Filing surfaces or profiles, however, are not suitable.

The first and the second burr machining element are flat on their working surfaces, which during the machining process only form a line-shaped or point-shaped contact with the burr surface.

Fig. 1 and 2 show a device for machining a burr 11 ( Fig. 5 ) an edge 10 of an elongated object 9, the device being equipped with a guide surface 1 on which the elongated object 9 can be guided along its length in a longitudinal direction 4. In addition, a protruding guide rod 17 is provided, which defines a further guide surface. The device according to the invention can preferably be used for machining the edge ridge of a ski, for example an alpine ski, the ski being moved with one of its edges 10 in the longitudinal direction 4 on the guide surface 1 and the ridge 11 being moved along with a first ridge machining element 2 and subsequently is processed with a second burr processing element 5.

In the exemplary embodiment shown, the guide surface 1 is embodied by spaced-apart support elements 101, 102 on which the elongated object 9 can slide in order to come into engagement with the first burr treatment element 2 and with the second burr treatment element 5. The Guide surface 1 could also be designed differently within the scope of the invention, for example without or with more than two bearing surfaces.

The first burr processing element 2 has a first burr processing surface 3 which is at a shallow angle a1 ( Fig. 7 ) or in alignment ( Fig. 6 ) is oriented to the guide surface 1, wherein the first burr processing element 2 is designed in the form of a substantially flat plate, and a top surface of the plate is the first burr processing surface 3.

In order to be able to set the machining angle, a first pivotable holder 7 is provided for the first burr machining element 2, via which the first burr machining element 2 can be adjusted about a pivot axis parallel to the longitudinal direction 4 in an angular range with an adjusting screw 14, the angular range having an aligned orientation and an orientation at a shallow angle with respect to the guide surface 1 includes.

The adjustable angular range of the first burr machining element 2 preferably comprises an angle a1 in the range from 0 ° to 1.5 °. If necessary, however, larger angles a1 can also be set.

Seen in the longitudinal direction 4, the first burr processing element 2 is followed by a second burr processing element 5 with a second burr processing surface 6 which is oriented at a steep angle or at a right angle to the guide surface 1.

During the burr machining process, the elongated object 9 hits with the burr 11 when moving along the guide surface 1 Edge 10 initially on the first burr processing surface 3 and then on the second burr processing surface 6.

The second burr processing element 5 is arranged at a distance from the first burr processing element 2, but can also adjoin this directly.

The second burr machining element 5 is designed in the form of an essentially flat plate, a top surface of the plate being the second burr machining surface 6. To adjust the angle of the second burr processing element 5, a second pivotable holder 8 is provided for the second burr processing element 5, via which the second burr processing element 5 can be adjusted about a pivot axis parallel to the longitudinal direction 4 in an angular range with an adjusting screw 12, the angular range having a vertical orientation and a Orientation at a steep angle with respect to the guide surface 1 includes.

The adjustable angular range of the second burr machining element 5 preferably comprises an angle a2 of 84 ° to 90 °. However, if necessary, an angle beyond this range can also be set.

The first burr machining element 2 and the second burr machining element 5 are made of materials that have grinding properties or cutting properties in the broadest sense and can be made of ceramic, diamond, stone, e.g. Arkansas, hardwood and all possible hard materials.

Fig. 8 and 9 show the edge 10 with a burr 11, as it is present after, for example, an edge grinding process. The ridge is 11 0.1 to 0.2 mm long, whereby the position of the ridge 11 is initially not precisely defined due to the coarse edge grinding process, the ridge edge is rounded and uneven in the longitudinal direction ( Fig. 9 ).

How out Figures 8 and 10 it can be seen that the side edge is inclined at 87 ° due to the grinding process and the base edge is inclined at 0.5 °. Fig. 10 and 11 show the state of the burr 11 after machining with the device according to the invention. The ridge surface marked F1 was set at an angle of 90 °. The point of intersection of the edge surfaces, i.e. of the side edge and the covering edge, serves as the reference point. When traveling along the ski edge 10 with the device according to the invention, the irregularly protruding ridge 11 is first straightened by the first ridge machining element 2 and turned over at a first angle, whereupon the second ridge machining element 5 moves the ridge 11 into the in Fig.11 shown final state. In this way, the adjustment screws 14 and 12 for the angular position of the first burr machining element 2 and the second burr machining element 5 can be used to set the desired angles with which the defined burr 11 in Fig.11 is achieved.
