Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wax scraper processing jig for performing edge regeneration processing of a wax scraper that scrapes off wax applied to a running surface of skis, snowboards, and the like, formation processing of a new edge, and the like.
[0002]
[Prior art]
Tools for scraping wax applied to the running surface of skis and snowboards include plastic and metal scrapers. Plastic scrapers are preferred because they are less likely to damage the running surface. However, when the scraper is brand new, the wax applied to the sliding surface can be scraped off neatly, but if the edge part wears out after repeated use, the wax cannot be scraped off neatly. If the worn scraper is used without being regenerated, the wax on the sliding surface cannot be maintained in a good condition, or the sliding surface may be damaged.
[0003]
Therefore, when the edge portion is worn during use, the angle of the edge portion of the scraper is generally reproduced or a process of forming a new edge is performed. Conventionally, as a processing method, the end of the clamped scraper is polished by applying a hand file to the end face, or the scraper held by hand is pressed against sandpaper fixed to a flat surface such as a table and polished. At present, reproduction of the angle of the edge portion and the like are performed.
[0004]
[Problems to be solved by the invention]
However, in the related art, the scraper is polished in an unstable state while deciding the angle by hand at present, so that the angle of the edge portion cannot be accurately reproduced. In addition, the linearity of the edge portion of the scraper was reduced while performing processing operations such as unstable reproduction many times, and as a result, the wax scraping property was deteriorated. . Further, since the polishing method is not stable, large burrs may be generated, and removal of the burrs may be troublesome.
[0005]
In view of the above circumstances, the present invention is directed to a wax scraper capable of efficiently performing a processing operation such as regeneration of an edge portion of a scraper under stable conditions, and consequently maintaining a good wax scraping property. It is intended to provide a processing jig.
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, a straight portion is formed on a side edge of a flat plate, and the wax applied to a sliding surface such as a ski or a snowboard is scraped off at an edge portion where an end surface of the straight portion intersects with the flat plate surface. A jig for processing the edge portion of the wax scraper, comprising a pedestal forming a main body of the jig, and a solid polishing surface fixed to the pedestal and having a flat polished surface against which an end surface of a linear portion of the scraper is pressed. And a guide surface fixed to the pedestal, and having a fixed angle with respect to the polishing surface of the file, and pressing the plate surface of the scraper against the guide surface, so that the scraper against the file when the scraper is moved. And a guide for keeping the angle constant.
[0007]
When processing the edge portion of the scraper using this jig, press the end surface of the linear portion of the scraper against the flat polishing surface of the file while lightly pressing the plate surface of the scraper against the guide surface. Move the scraper along the guide surface. By doing so, while being guided by the guide surface, the end surface of the linear portion of the scraper is smoothly polished by the sanding surface of the file while maintaining a constant angle with respect to the plate surface. Therefore, the angle of the edge portion where the plate surface intersects with the end face of the linear portion is controlled to be constant, and the linearity of the edge is maintained high.
[0008]
When the polishing by the jig is completed, the burr generated by the polishing can be removed by operating the cutter along the plate surface of the scraper. Also in this case, the polishing conditions are stable and large burrs are less likely to occur, so that the operation can be simplified.
[0009]
As described above, the scraper can be polished in a stable posture while determining the polishing angle by the guide, so that the processing of the angle of the accurate edge portion can be efficiently performed, and as a result, the scraping property of the wax can be improved. Will be able to keep it.
[0010]
According to a second aspect of the present invention, in the first aspect, the guide surface is provided perpendicular to a polishing surface of the file.
[0011]
When the guide surface is provided perpendicular to the polishing surface of the file in this manner, the end face of the linear portion can be finished perpendicular to both plate surfaces (front and back surfaces) of the scraper. The angle of both edges can be reproduced or formed at a precise right angle, and the wax can be scraped off under the same conditions using either edge.
[0012]
The invention according to claim 3 is characterized in that, in claim 1 or 2, a guide is detachably fixed to the pedestal by a fastening member, and a file is sandwiched and fixed between the pedestal and the guide.
[0013]
When the file is clamped and fixed between the base and the guide in this way, the file can be easily removed by removing the guide, so that the polished surface of the file can be sharpened easily, and the roughness of the file can be reduced. When using a different file, you can easily change the file.
[0014]
According to a fourth aspect of the present invention, in the third aspect, a rectangular parallelepiped file having a bottom surface and a side surface orthogonal to each other and having an upper surface parallel to the bottom surface as the polishing surface is provided as the file, and a top surface of the pedestal is provided. Forming a step having substantially the same height as the height of the file, setting the bottom surface of the step as a file mounting surface and the vertical surface of the step as a file positioning surface, and setting the bottom of the file as the mounting surface described above. And the side surface of the file is brought into contact with the positioning surface, and in this state, the guide is placed on the upper surface of the step of the pedestal so that the portion provided with the guide surface covers the polishing surface of the file. It is characterized in that the file is clamped and fixed between the pedestal and the guide by mounting and fixing the guide to the pedestal with the fastening member.
[0015]
When the step for setting the file is provided on the pedestal, the positioning of the file can be easily performed by the step. In addition, by fixing the guide to the pedestal by the fastening member, the upper surface of the file placed on the bottom surface of the step of the pedestal can be directly pressed by the guide. Therefore, the guide surface can be directly raised from the polished surface of the file, and the stability of the guide action when polishing the scraper can be increased.
[0016]
According to a fifth aspect of the present invention, in the fourth aspect, the guide includes a standing plate having a guide surface on a front surface and a bottom plate bent in an L-shape from a lower end of the standing plate to a rear side and placed on an upper surface of a step portion of the pedestal. The L-shaped aluminum guide is provided with a positioning protrusion for positioning the guide by regulating the position of the rear edge of the bottom plate of the L-shaped aluminum guide on the upper surface of the step of the base, and the guide is positioned by the positioning protrusion. In this state, it is fixed to the pedestal with a plurality of screws as fastening members.
[0017]
By providing the projection for positioning the guide on the pedestal, disassembly and assembly at the time of attachment / detachment or replacement of the file can be easily performed. Further, since the rigidity required for the guide can be reliably maintained by adopting the L-shaped aluminum guide, stable polishing conditions can be easily created. In addition, since a plurality of screws are used as the fastening members, disassembly and assembly can be easily performed by tightening and removing the screws.
[0018]

Edges 6 and 7 that intersect with 4 and 5 are used to scrape off the wax applied to the running surface of skis, snowboards and the like.
[0020]
The processing jig 10 of the embodiment is a tool for processing the edge portions 6 and 7 of the scraper 1 described above, and includes, for example, a wooden pedestal 11 serving as a main body of the jig, and a metal-made solid file 12. And an L-shaped aluminum guide 13 made of aluminum, and two screws (fastening members) 14 for detachably fixing the L-shaped aluminum guide 13 to the pedestal 11.
[0021]
The file 12 has a rectangular parallelepiped block shape elongated in one direction, has a bottom surface 12a and a side surface 12b orthogonal to each other, and presses an upper surface 12c parallel to the bottom surface 12a with the end surface 3 of the linear portion 2 of the scraper 1. This is a flat polished surface 15 to be obtained. The file 12 is preferably, for example, a wave file. This is because the polishing scrap can be swept well and the finish of the polished surface becomes smooth.
[0022]
The pedestal 11 has, on the upper surface, a step portion 17 having a height substantially equal to the height of the file 12 (it is preferable to set the height slightly lower in consideration of the elasticity of the wooden pedestal 11). The bottom surface 17a of the step 17 is used as the mounting surface of the file 12, the vertical surface 17b of the step 17 is used as the positioning surface of the file 12, and the rear surface of the upper surface 17c of the step 17 is located behind the L-shaped aluminum guide 13. The positioning projection 18 for positioning the guide 13 by regulating the position of the edge is provided.
[0023]
The L-shaped aluminum guide 13 has a guide surface 20 perpendicular to the polishing surface 15 of the file 12. The L-shaped aluminum guide 13 has a vertical plate 13 a having the guide surface 20 on the front surface, and a bottom plate 13 b which is bent L-shaped from the lower end of the vertical plate 13 a to the rear side and rests on the upper surface 17 c of the step 17 of the pedestal 11. The scraper 1 is an L-shaped member, and has a function of keeping the angle of the scraper 1 with respect to the file 12 when the scraper 1 is moved by pressing the plate surface 5 of the scraper 1 against the guide surface 20.
[0024]
In the processing jig 10, the bottom surface 12 a of the file 12 is placed on the bottom surface (mounting surface) 17 a of the step 17 of the base 11, and the side surface 12 b of the file 12 is placed on the vertical surface of the step 17 of the base 11. (Bottom positioning surface) 17b. In this state, guide 13 is provided such that standing plate 13a provided with guide surface 20 is placed on polishing surface 15 of file 12 on upper surface 17c of step 17 of pedestal 11. Is mounted, and the guide 13 is detachably fixed to the pedestal 11 with two screws 14, whereby the file 12 is sandwiched and fixed between the pedestal 11 and the guide 13. In this case, the L-shaped aluminum guide 13 is positioned by abutting the rear end edge 13c of the bottom plate 13b against the positioning projection 18, and in this state, the upper surface 12c (polishing surface 15) of the file 12 is aligned with the width direction. It covers up to about half.
[0025]
Next, the operation will be described.
When processing the edge portions 6 and 7 of the deteriorated scraper 1 using the processing jig 10, first, the processing jig 10 is fixed on a work table (not shown). Then, while lightly pressing the plate surface 5 of the scraper 1 against the guide surface 20, the end surface 3 of the linear portion 2 of the scraper 1 is pressed against the flat polishing surface 15 of the file 12 with a force of 2 to 3 kg. The scraper 1 is moved in one direction about three to four times along the guide surface 15. By doing so, the end surface 3 of the linear portion 2 of the scraper 1 is precisely and vertically polished to the plate surfaces 4 and 5 by the polishing surface 15 of the file 12 while being guided by the guide surface 20. Can be. Therefore, the angles of the edge portions 6 and 7 at which the plate surfaces 4 and 5 intersect with the end surface 3 of the linear portion 2 can be reproduced at a high accuracy at a right angle, and the linearity of the edge portion 2 is maintained high. Can be.
[0026]
When the polishing by the processing jig 10 is completed, the burrs generated by the polishing can be easily removed by operating the deburring cutter along the plate surfaces 4 and 5 of the scraper 1. Also in this case, the polishing conditions are stable and large burrs are less likely to occur, so that the operation can be simplified.
[0027]
As described above, the scraper 1 can be polished in a stable posture while the polishing angle is determined by the guide 13, so that the angles of the edge portions 6 and 7 can be accurately reproduced efficiently, and as a result, the wax Good scraping properties can be maintained.
[0028]
In this case, since the guide surface 20 is set perpendicular to the polishing surface 15 of the file 12, the end surface 3 of the linear portion 2 is opposed to both plate surfaces (front and back surfaces) 4, 5 of the scraper 1. It can be finished vertically, and the angles of both edge portions 6 and 7 in the plate thickness direction in the linear portion 2 can be reproduced at a right angle with high accuracy. Therefore, the wax can be scraped off under the same conditions using either of the edge portions 6 and 7.
[0029]
Further, since the file 12 is sandwiched and fixed between the pedestal 11 and the guide 13, if the screw 14 is loosened and the guide 13 is slightly lifted, the file 12 can be easily removed. Therefore, the file 12 can be removed to sharpen the polished surface 15, and the file 12 can be easily replaced even when using a file 12 having a different grain size. In addition, in one set state, only one half of the polishing surface 15 of the file 12 is used for polishing (that is, the other half is hidden by the guide 13 and is not used), so that the direction of the file 12 is reversed. Once again, the other half can be used for polishing. In addition, by forming a polishing surface on the bottom surface 12a side, the upper and lower surfaces can be used for polishing by changing the file 12 upside down.
[0030]
Further, since the pedestal 11 is provided with the step portion 17 for setting the file 12, the positioning of the file 12 can be easily performed by the step portion 17. Further, since the upper surface 12c of the file 12 placed on the bottom surface 17a of the step 17 of the pedestal 11 is directly pressed down by the guide 13, the guide surface 20 can be raised directly from the polished surface 15 of the file 12. The guide for polishing 1 is stable.
[0031]
In addition, since the pedestal 11 is provided with the convex portion 18 for positioning the guide 13, the disassembly / assembly at the time of attachment / detachment or replacement of the file 12 can be simplified. Furthermore, since the L-shaped aluminum guide 13 which can securely maintain the required rigidity as a guide is adopted, stable polishing conditions can be easily created, and two screws 14 are used as fastening members. Therefore, the screw 14 can be easily disassembled and assembled by tightening and removing the screw 14.
[0032]
In the above embodiment, the angle of the guide surface 20 is set to be perpendicular to the polishing surface 15, but may be set to an angle other than the right angle.
[0033]
