Detailed Description
The invention provides a novel skates, which is provided with a sharp-top sawtooth structure at the blade, so that the contact area between the blade of the skates and the ice surface is reduced, the forward sliding resistance of the skates is reduced, and the ice-pushing force during ice pushing can be improved.
The present invention will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent.
1. Ice skates
According to a first aspect of the present invention, an ice blade is provided.
In one exemplary embodiment of the present invention, an ice blade is provided. Fig. 1 is an enlarged schematic view of the whole and part of a blade edge of an ice blade according to an embodiment of the invention. As shown in fig. 1, the skates of the present embodiment are characterized in that: the blade part is in a sharp-top sawtooth shape.
In this example, the skates were stainless steel quick skates with a length of 430mm (17 inches), a thickness of 1.1mm, and a width of 24mm at the top arc position. With respect to the other portions of the present embodiment than the blade, reference is made to the related description of the prior art, and detailed description thereof will not be given here.
With continued reference to fig. 1, the serrations are periodically arranged at equal intervals along the length of the skates at the blade edge portion. The inventors of the present invention have also made experiments on non-equally spaced serrations, and the results of the experiments indicate that although non-equally spaced serrations reduce the resistance to some extent, the resistance to equally spaced periodic serrations is comparatively smaller.
Specifically, in this embodiment, the saw tooth is a right triangle-shaped sharp tooth, the tooth tip angle α=45°, the included angle β=135° between the hypotenuse direction of the saw tooth and the advancing direction of the skates, the tooth height h is 1mm, and the tooth pitch s is 1mm.
It should be noted that "tip" in "tip serration" of the present invention is merely a relative concept, and refers to: the width of the tip portion of the individual serrations "in contact with the ice surface" is less than 1/3 of the width of the root portion "away from the ice surface". The technical proposal of processing the tooth tip part which is contacted with the ice surface into a round angle is still within the protection scope of the invention. Here, in the technical scheme of processing the "tooth tip portion in contact with the ice surface" into the rounded corner, although the resistance can be reduced to some extent, the technical scheme of "the sawtooth shape is a right triangle-shaped pointed tooth" in the present embodiment is inferior in the aspect of improving the ice-pushing force.
Based on the present embodiment, the inventor also proposes other technical solutions, and found that the skates under the following conditions also have the effect of reducing resistance: the value range of the tooth sharp angle alpha is 30-60 degrees, the included angle beta between the bevel edge of each tooth and the advancing direction of the skates is an obtuse angle, the range of the included angle is 120-150 degrees, the value range of the tooth height h of each tooth is 0.1-2 mm, and the value range of the tooth pitch s is 0.058-3.46 mm. With a saw tooth structure outside this range, the drag reducing effect will be significantly reduced.
The material of the skates may be stainless steel, spring steel, high-speed steel or tool steel. Through experiments, after the technical scheme of the invention is adopted, the ice skates made of different materials have the same drag reduction effect.
With continued reference to fig. 1, the arrows represent the water flow direction. When the skates 1 of the embodiment slide on the ice surface 4, the saw-tooth structure of the skates blade forms low-speed micro-eddies 2, and the low-speed micro-eddies 2 serve as miniature water bearings, so that the solid-liquid contact sliding friction between the blade and the ice surface water film 3 is converted into liquid-liquid contact rolling friction between the blade surface miniature water bearings and the ice surface water film 3, thereby reducing the contact area between the skates blade and the ice surface, reducing the forward sliding resistance of the skates, and improving the tribological performance of the skates.
In addition, under the condition that a user uses the skates of the embodiment, when the skates act backwards to pedal ice, due to the existence of the sawtooth sharp teeth, acting force between the skates and the ice surface in the sliding process is increased, effective ice-pedal force is provided for skaters, and the driving efficiency of the skates is improved.
2. Preparation method of skates
According to a second aspect of the present invention, there is provided a method for manufacturing an ice skate according to the first embodiment, and the features of the ice skate in terms of structure and material may be referred to the description of the above embodiments, which will not be repeated.

Sequentially carrying out ultrasonic cleaning on the ice blade to be processed in ethanol and deionized water by adopting a KQ-600DE type numerical control ultrasonic cleaner, wherein the ultrasonic power is 480W, and the ultrasonic time is 30min each time. And placing the cleaned ice blade in a KLG-9205A constant temperature blast drying box, and drying at 20 ℃ for 120min to obtain the clean surface.
Step A, fixing the skates in the water tank upwards through the side surfaces of the skates support, fixing the water tank on the one-dimensional displacement platform, and then injecting purified water into the water tank until the liquid level of the purified water is higher than the cutting edge of the skates;
referring to fig. 3, a water tank 9 with a connection port 10 at the bottom is fixed on a one-dimensional displacement platform 11 and can move along with the one-dimensional displacement platform 11. The ice blade to be processed is horizontally fixed in the water tank 9 by utilizing the ice blade support part, and laser vertically enters the side wall surface of the edge of the ice blade to be processed downwards. The size of the water tank is 500 multiplied by 200mm, purified water is injected into the water tank through the connecting port 10 until the liquid level reaches 1cm above the side wall of the skates, and the side wall surface of the skates to be processed is adjusted to the focal plane position of the scanning vibrating mirror 8.
Through a plurality of experiments, the invention can be realized by preferably that the liquid level of the purified water in the water tank is 0.5 cm-1.5 cm higher than the height of the blade of the skates. It will be appreciated that other transparent safety liquids besides purified water may be injected into the tank as an auxiliary processing transparent liquid, and will not be described in detail here.
As will be appreciated by those skilled in the art, the multiple laser processing of the blade edge in the environment of the auxiliary processing of the transparent liquid can be performed, and the heat generated by the laser processing can be rapidly absorbed by the auxiliary processing of the transparent liquid, so that the blade edge is ensured to maintain the optimal processing temperature all the time, and deformation and cracking of the blade edge due to the local instantaneous high temperature during the laser processing process are greatly reduced. In addition, the good laser permeability of the pure water layer of 0.5 cm-1.5 cm can avoid the extra consumption of laser, and the processing precision is not affected.
Compared with the method that the whole light guide device or the scanning galvanometer is completely immersed in water, the preparation method can prevent the influence of water flow fluctuation on laser conduction, improve the accuracy of laser processing, and avoid the extra cost caused by the water-proof treatment of the light guide device.
Step B, the laser and the light guide device are optically connected, so that laser emitted by the laser can be focused on a position to be processed of the blade of the skates through the light guide device, and the control device is electrically connected with the one-dimensional displacement platform, the laser and the light guide device, so that the control device can control the three;
in this embodiment, the laser 6 is a fiber laser, the processing wavelength is 1064nm, the repetition rate is 20kHz, and the pulse width is 100ns. It will be appreciated by those skilled in the art that solid state lasers, gas lasers or semiconductor lasers may be used in addition to fiber lasers, provided that the relevant power requirements are met.
In this embodiment, selecting the light guiding means based on the selected fiber laser 6 includes: an optical fiber 7 and a scanning galvanometer 8. Wherein, as shown in fig. 3, the control device 5 controls the laser 6 to output laser light according to preset power; the output laser is transmitted to a scanning galvanometer 8 through an optical fiber 7 and is focused at a position to be processed of the blade of the skates. The control device 5 controls the deflection of the reflecting mirror in the scanning galvanometer 8 and the movement of the one-dimensional displacement platform 11, so as to realize the laser processing of different positions to be processed on the blade of the skates. In the initial stage of processing, the control device 5 controls the scanning point of the scanning galvanometer 8 to be positioned at the initial position.
It should be noted that, for the processing of the serrated structure of the blade edge of the skates, the mode of linkage of the scanning galvanometer and the displacement platform adopted by the invention is only one of the processing modes, and the mode can also be one of the following modes:
(1) the laser output laser is transmitted to the scanning vibrating mirror, the water tank (the ice blade is fixed in the water tank) is fixed, and the integral processing of the ice blade edge is realized through the deflection of the scanning vibrating mirror; or (b)
(2) The laser output laser is conducted to the surface of the skates through the reflecting mirror, the water tank (internally fixed with the skates) is fixed on the two-dimensional displacement platform and moves along with the two-dimensional displacement platform, and the integral processing of the skates is realized through the movement of the two-dimensional displacement platform.

It will be appreciated by those skilled in the art that the above several ways of machining can be accomplished as long as the machining of the saw tooth structure of the blade edge is compatible with the type of laser selected. Compared with the processing mode, the mode of linkage of the scanning galvanometer and the displacement platform is adopted, so that the high-efficiency processing characteristic of the scanning galvanometer is utilized, and the defect of poor edge processing precision when the scanning galvanometer is processed in a large area is overcome by combining the displacement platform. By adopting the mode, the invention can realize the fine processing of the serrated structure of the blade of the skates with high efficiency, large area and low cost.

Those skilled in the art will appreciate that in accordance with the current state of the art lasers, the use of high power lasers directly allows for the machining of the peaked sawtooth structures described above. However, the inventors of the present invention found that: high power laser processing results in localized deformation and cracking, which results in accuracy and effects that are compromised. Accordingly, the inventors have proposed a method employing fractional processing.
In this example, the blade of the skates was machined 55 times. In each machining, the machining power of the laser was controlled to be 24W so that only 20 μm was removed at a time. After each processing is finished, a certain time is reserved, and the next processing is carried out after the temperature and mechanical properties of the blade of the skates are recovered.
Although the present invention divides the processing into 55 times, in other embodiments of the present invention, the number of processing times may be set to other numbers, that is: the processing of the serrated structure of the skates blade is performed in N times, and only 1/N of the thickness of the skates blade is removed each time, wherein N is larger than or equal to 5.
2. For each machining, the machining of the peaked sawtooth structure of the skates blade is controlled by the control device 5
The procedure of the control device 5 is to set up teeth with a right triangle shape, the tooth tip angle alpha is 45 degrees, the tooth height h is 0.5mm, and the tooth pitch s is 0.5mm. And carrying out solid modeling on the skates and the water tank by using modeling software to generate corresponding coordinate points and path data sets.

The control device 5 is also connected to the one-dimensional displacement platform 11, so that the displacement of the upper water tank and the skates can be controlled. The program in the control means 5 enables an accurate control of the laser machining path and a fine machining of the saw-tooth structure of the blade on the basis of the data set generated by the solid model.
In this embodiment, the scanning range of the scanning galvanometer 8 is 200mm×200mm, and the moving range of the one-dimensional displacement stage 11 is 300mm. Utilizing Solidworks software to fix ice skates workpiece to be processed insideThe water tank 9 is used for solid modeling, and the ice blade to be processed is processed in three sections along the length direction in Solidworks software.
