Detailed Description
The invention provides a novel ice skate, which is characterized in that a sharp-top sawtooth structure is arranged at a blade, so that the contact area of the blade of the ice skate and an ice surface is reduced, the forward sliding resistance of the ice skate is reduced, and the ice pedaling force during ice pedaling can be improved.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
One, ice skate blade
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 view of the blade of the ice blade according to the embodiment of the present invention. As shown in fig. 1, the ice blade of the present embodiment is characterized in that: the blade part is in a sharp-top sawtooth shape.
In this embodiment, the skate is a stainless steel quick-skating skate, the length of the skate is 430mm (17 inches), the thickness of the skate is 1.1mm, and the width of the skate at the top arc position is 24 mm. Regarding the parts other than the blade in the present embodiment, reference may be made to the related description of the prior art, and the detailed description is omitted herein.
With continued reference to FIG. 1, at the blade portion, the serrations are periodically arranged at equal intervals along the length of the skate blade. The inventor of the invention also conducts experiments on the saw tooth arrangement which is not arranged at equal intervals, and the experimental results show that although the resistance of the saw teeth which are not arranged at equal intervals can be reduced to a certain extent, the resistance of the saw teeth which are arranged at equal intervals and in cycles is smaller.
Specifically, in this embodiment, the sawtooth shape is a right triangle-shaped sharp tooth, the tooth tip angle α is 45 °, the angle β between the direction of the hypotenuse of the sawtooth and the advancing direction of the ice blade is 135 °, the tooth height h is 1mm, and the tooth pitch s is 1 mm.
It should be noted that the "tip" in the "tip saw tooth" of the present invention is only a relative concept, which means: the width of the "tip portion in contact with the ice surface" of the individual serration is smaller than the width of the "root portion away from the ice surface" 1/3. The technical scheme of processing the tooth tip part contacting with the ice surface into the round angle still remains in the protection scope of the invention. Here, in the technical solution of processing the "tooth tip portion contacting the ice surface" into a rounded corner, although the resistance can be reduced to some extent, the technical solution of "the zigzag shape is a right-angled triangular pointed tooth" in the present embodiment is inferior in terms of improving the kicking force.
On the basis of the embodiment, the inventor also provides other technical solutions, and finds that the ice skate blade also has the effect of reducing the resistance when the following conditions are met: the range of the tooth tip angle alpha is 30-60 degrees, the included angle beta between the bevel edge of the sharp tooth and the advancing direction of the ice skate is an obtuse angle, the range is 120-150 degrees, the range of the tooth height h of the sharp tooth is 0.1-2 mm, and the range of the tooth pitch s is 0.058-3.46 mm. With the saw-tooth structure outside this range, the drag reduction effect will be significantly reduced.
The material of the ice blade may be stainless steel, spring steel, high speed steel or tool steel. Experiments prove that the ice skates made of different materials also have the anti-drag effect after the technical scheme of the invention is adopted.
With continued reference to FIG. 1, the arrows indicate the direction of water flow. When the ice skate 1 slides on the ice surface 4, the low-speed micro-vortexes 2 are formed in the sawtooth-shaped structure of the blade of the ice skate, and the low-speed micro-vortexes 2 serve as micro water bearings, so that 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 micro water bearings on the blade surface and the ice surface water film 3, the contact area between the blade of the ice skate and the ice surface is reduced, the forward sliding resistance of the ice skate is reduced, and the tribological performance of the ice skate is improved.
In addition, under the condition that the user uses the ice skate of the embodiment, when the ice skate acts backwards to kick ice, the acting force between the blade of the ice skate and the ice surface in the sliding process is increased due to the existence of the sawtooth sharp teeth, so that effective ice kicking force is provided for ice skaters, and the driving efficiency of the ice skate is improved.

It will be appreciated that other transparent safety fluids than purified water may also be injected into the tank as an auxiliary processing transparent fluid and will not be described in detail herein.
The technical personnel in the field can understand that when the laser processing is carried out on the blade of the ice skate for a plurality of times in the environment of auxiliary processing of the transparent liquid, the heat generated by the laser processing can be quickly absorbed by the auxiliary processing of the transparent liquid, so that the blade of the ice skate is always kept at the optimal processing temperature, and the deformation and the cracking of the blade of the ice skate caused by local instantaneous high temperature in the laser processing process are greatly reduced. In addition, the good laser transmission performance of the pure water layer of 0.5 cm-1.5 cm can avoid the additional consumption of laser, and the processing precision is not influenced.
Compared with the method that the whole light guide device or the scanning galvanometer is completely immersed in water, the preparation method provided by the invention can prevent the influence of water flow fluctuation on laser conduction, improve the accuracy of laser processing and avoid extra cost caused by waterproof treatment on the light guide device.
B, optically connecting the laser and the light guide device to enable the laser emitted by the laser to be focused on the position to be processed of the blade of the ice skate through the light guide device, and electrically connecting the control device with the one-dimensional displacement platform, the laser and the light guide device to enable the control device to control the three;

It will be appreciated by those skilled in the art that solid state, gas or semiconductor lasers may be employed in addition to fiber lasers, so long as the associated power requirements are met.
In the present embodiment, the selecting the light guide means based on the selected fiber laser 6 includes: an optical fiber 7 and a scanning galvanometer 8. As shown in fig. 3, the control device 5 controls the laser 6 to output laser light according to a preset power; the output laser is transmitted to a scanning galvanometer 8 through an optical fiber 7 and is focused at the position to be processed of the blade of the ice skate. 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 ice skate. In the initial stage of the machining, the control device 5 controls the scanning point of the scanning galvanometer 8 to be at the initial position.
It should be noted that, for the processing of the serrated structure of the blade of the ice skate, the method of linking the scanning galvanometer and the displacement platform adopted by the present invention is only one of the processing methods, and it may be one of the following methods:
firstly, laser output by a laser is conducted to a scanning galvanometer, a water tank (an ice skate is fixed inside the water tank) is fixed, and the integral processing of the cutting edge of the ice skate is realized through the deflection of the scanning galvanometer; or
Secondly, laser output by the laser is transmitted to the surface of the ice skate through the reflecting lens, the water tank (the ice skate is fixed inside) is fixed on the two-dimensional displacement platform and moves along with the two-dimensional displacement platform, and the integral processing of the cutting edge of the ice skate is realized through the movement of the two-dimensional platform.

It will be appreciated by those skilled in the art that the above processing methods can be used to form the serrated structure of the blade of the ice skate, as long as the selected type of laser is used. Compared with the processing mode, the mode of linkage of the scanning galvanometer and the displacement platform is adopted, on one hand, the characteristic of high-efficiency processing of the scanning galvanometer is utilized, and on the other hand, the defect of poor edge processing precision of the scanning galvanometer during large-area processing is overcome by combining the displacement platform.

It will be appreciated by those skilled in the art that, in accordance with the current state of the art of lasers, the steeple tooth structure described above can be machined directly with a high power laser. However, the inventors of the present invention found that: high power laser machining results in local deformation and cracking, which affects accuracy and effectiveness. Therefore, the inventors propose a method using the split processing.

After each time of processing is finished, a certain time is set, and after the temperature and the mechanical property of the blade of the ice skate are recovered, the next processing is carried out.

In addition, 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 ice skate can be controlled. The program in the control device 5 enables precise control of the laser machining path and fine machining of the blade serration structure based on the data set generated by the solid model.
