Description

             The invention relates to sports and relates to the design of a device for sharpening a blade of a speed skate.

            Sharpening of skates is done so that the working surface of the blade is an absolutely smooth plane with a right angle to the wall of the blade. Workers are both ribs. Sharpen the skates manually on special machines in which both skates are fixed with the blades up parallel to each other. First, sharpening is done with one wide bar, in order to form a smooth edge with an angle of 90 degrees, and then with a thinner bar for grinding the plane of the blades to a mirror state. No burrs, uneven edges, or any suspicions of a groove in the blade are allowed, as this leads to a sharp increase in resistance when the blade moves on ice. In hockey and figure skating, on the contrary, a very thick blade is sharpened under the groove, with a radius of 10-15 mm, forming two sharp cutting edges. All this is done because in hockey and figure skating the speed of skating is absolutely not important, but reliable grip with ice is important for all maneuvers and pirouettes. The blade of the skating ridge glides over the surface of the ice, but does not cut it (http://speed-skater.ru/clape_skate).

          For sharpening the blades of skates made with grooves (grooves) on the sliding end face, special devices are used.

         From the USSR author's certificate No. 78809 for the invention, a hand-held device for a point of skates is known, which is made in the form of a replaceable file with a double-sided notch, fortified between two plates turning into a round handle of the device, which serve as guides for the ridge blade.

          The disadvantage of the device according to the USSR AS No. 78809 is that it does not allow sharpening the blade of the skating skate with a groove (groove) on its end surface, since the file does not allow sharpening the groove on high alloy steel from which the blades of speed skating are made.

From patent document No. CN201862239 for a utility model, equipment for treating a ridge blade is known, which comprises a rack provided with a feed and cutting mechanism comprising a front beam and a rear beam; front beam and rear beam are located on the rack; emphasis for skates is located between the front beam and the rear beam; the feed motor is located on the rear beam;

the output shaft of the feed motor is connected to one end of the feed screw; and the other end of the feed screw rotates on the rear beam. The cutting edge of the ridge blade is machined with groove processing equipment to significantly improve the sliding speed of the ridge blade on the ice surface. Since the equipment for processing the blades for skates is equipped with a profiling mechanism, production efficiency can be improved on the basis of ensuring the quality of processing of the blades for skates.

           A disadvantage of the known equipment is its complexity, inconvenience in operation.

          The skate blade sharpening equipment with a groove according to patent document No. CN201862239 was selected as the closest analogue.

          The technical problem when creating a device for sharpening a blade of a skating skate is providing ease of use, simplicity and reliability.

          The technical result achieved by the invention in terms of a device for sharpening a blade of a skating ridge is ease of use, simplicity and reliability.

          The technical result is ensured by the fact that in the device for sharpening the blade of the skating ridge, characterized by the presence on the end surface of the blade of the longitudinal groove containing the cutting disk, according to the invention, the cutting disk is located between two cheeks made of durable material, the plane of the disk and the cheeks are parallel to each other, when the disk and cheeks are rigidly fixed on a common axis, the cheeks are mounted symmetrically to each other at a distance corresponding to the thickness of the ridge blade and ensuring the placement of the blade between the cheeks, each cheek contains the first two opposite sides, made rectilinear, parallel to each other, located at a distance of not more than 15 mm from each other, the other two opposite sides of each cheek are made arcuate with a radius greater than the radius of the cutting disk with the formation of a groove, limited on the one hand facing each other's inner opposite surfaces of both cheeks, and on the other hand, the front side of the cutting disc.

         The depth of the groove can be from 0, 8 to 1, 2 cm.

         The distance between the cheeks can be 1, 15 mm.

         The authors proposed the following design for sharpening the blade of the skating ridge, which provides for the execution on its end surface of the groove with the necessary parameters.

The device contains a metal cutting disc coated with diamond chips on a copper-tin base, placed between two side cheeks. Cutting 3

the disk and cheeks are mounted on a common axis of symmetry and are rigidly fixed relative to each other. Cheeks are located symmetrically opposite each other.

         Each cheek is made of durable material as follows.

         The first two opposite lateral sides of each cheek are parallel to each other and are located at a distance of no more than 15 mm from each other in order to ensure the free passage between the blades of the ridge with almost any bending radius.

         Two second opposite sides of each cheek are located at a distance from the axis of rotation greater than the radius of the disk so that from these sides of the cheeks the disk does not extend beyond the cheeks. This is necessary to ensure the reliability of the retention of the blade of the ridge in the device, for the convenience of holding the device and to ensure the safety of the person sharpening the blade of the skate.

         Between the protruding parts of both cheeks, a groove is formed, limited, on the one hand, facing the inner side surfaces of the cheeks, and, on the other hand, the end (working) surface of the cutting disc.

         For reliable retention of the ridge blade in the device, it is advisable that the edges of the cheeks protruding beyond the disk are at a distance from the disk edge from 0.8 to 1.2 mm. This is enough to ensure reliable retention of the blade in the device, as well as to ensure the safety and ease of use for the person sharpening the blade.

         The cheeks are spaced from each other at a distance corresponding to the thickness of the blade of the skating ridge, for example, at a distance of 1, 15 mm.

         Cutting a groove (grooves) using the inventive device is as follows.

         A lubricant-cooling fluid (coolant) is applied to the treated surface of the ridge blade. The device is installed with a groove on the workpiece surface of the ridge blade until it stops in the cutting edge of the disk. Next, they make smooth longitudinal movements along the length of the blade with constant disk pressure on the machined end surface of the blade. The depth of the groove during sharpening can be controlled by any known means, for example, a T-shaped template, in which the average vertical section along the length corresponds to the depth of the groove.

         The inventive device for sharpening the blade of the skating skate is simple, reliable, safe, easy to use, mobile. Allows you to sharpen the blades of speed skates made with any radius.

         The claimed invention is illustrated by drawings.
