Abstract
The utility model discloses a high-speed steel coated ice skate-blade which is composed of a knife back, blades and a coat. The utility model is characterized in that both sides of each of the blades are coated with thin titanium nitride or titanium carbide, and the whole knife blade adopts bimetal clad steel. After the utility model is mulled and is sharply ground, the blades with high-hardness (HRC80-85) and low roughness (Ra0.1-0.2) are formed on both sides; thus, under the condition of no reduction to the toughness of the ice skate-blade, the service life of each of the blades of the ice skate-blade is greatly extended, friction force between the ice skate-blade and an ice surface is reduced, and sliding velocity is raised.
Description
The utility model belongs to athletic sports appliance on ice, particularly a kind of coated high speed steel skates.The domestic and international at present skates of producing, blade section adopts whole high-quality steel to make more, along with the continuous development of ice-sports, it is found that existing skates exist a lot of problems and shortcoming, have a strong impact on the raising of ice-sports person's skill and speed.Comprehensive these problems and shortcoming, show that mainly blade is easily blunt, life-span is short, it is big etc. to slide friction, according to some experienced outstanding ice-sports person's reflections, when the senior skates of import slide 8000 meters left and right sides, blade just begins to send out blunt, " skates are not eaten ice " phenomenon appears, and general homemade skates this phenomenon just occurs at 3000-5000 rice, in order to address this problem, people are except working hard on material, and the hardness (being generally HRC68-72) of the raising blade of also trying one's best is because improve the wearability that hardness not only can increase blade, but also can reduce the roughness of blade, (the senior skates Ra=0.8-0.4 of import) reduces the frictional force between blade and the ice, but the hardness of blade is when too high, reduced the toughness of blade again, even the injury sportsman.
The purpose of this utility model just provides a kind of wear-resisting, good toughness, coated high speed steel skates that friction is little.
In order to achieve the above object, the blade of the utility model coated high speed steel skates is made up of the knife back, blade and coating layer portion.Be coated with titanium nitride or titanium carbonitride in the both sides of blade, coating layer thickness is 0.002-0.008mm, the hardness of coating can reach HRC80-85, because blade body hardness is moderate, thereby guaranteed the toughness of skates, and coating as thin as a wafer, extremely hard, the process that slides at the cutter mill, the blade body wear of mid portion is fast, thereby forms a groove (see figure 3) on the cross section of whole blade, and the coating of both sides high rigidity, low roughness is exactly the blade that contacts with ice.
Specific embodiments below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is the front view of skates blade, Fig. 2 is a side view, Fig. 3 is " D " partial enlarged drawing, integral knife blade is by knife back part 1, knife edge part 2 and coating 3 are formed, it is the bimetallic clad steel for integral body that the integral body of blade adopts bimetallic clad steel or high speed steel material, the material 4 chromium 2 molybdenum vanadium nickel (4Cr2MoVNi) of knife back part 1, knife edge part 2 adopts tungsten 2 molybdenums 9 chrome alum cobalt 8 (W2Mo9CrVCo8) materials, two-part in conjunction with adopting the butt welding of electron beam vacuum, knife edge part 2 quenching hardness are HRC67-69, for integral body is high-speed steel, for the knife edge part 1 that obtains better elastic hardness (HRC45-50) and the knife edge part 2 of higher hardness HRC (66-69), adopt selective hardening or integral body to quench to high rigidity, handle with the method for differential annealing again.After said procedure finishes, is t=0.002-0.008mm with deposition or other method at the both sides of knife edge part 2 coated, titanium nitride (TiN) or the titanium carbonitride (TiNC) of height h=5-10mm, again the coating of knife edge part 2 is ground, make two side plane roughness Ra0.1-0.2, again cutting edge of a knife or a sword is ground with abrasive method in the blade bottom at last, the work of manufacturing of whole blade has just been finished, as for the manufacturing of whole skates, still can be undertaken by general traditional method.
Characteristics of the present utility model are:
1. slide the life-span long (for the 8-10 of general skates doubly).
2. blade roughness low (Ra0.1-0.2) has therefore reduced the frictional force between blade and the ice widely, thereby has reduced sliding force.When being the pulling force contrast test of 20Kg as skates being done load, Holland's " pirate " cutter is 275g, and homemade cutter is 300g, and the utility model is 250g.
3. skates good toughness, being difficult for property phenomenon of rupture.
