Abstract
The utility model relates to a cutting tool. The utility model comprises a cutting tool base body (1) and a cutting blade (2), wherein, the cutting blade (2) is a hardened blade covered with a melted and clad alloy hardening layer, and a melted and clad alloy layer (21), a hardening layer (22) and a base body are arranged at the position of the cutting blade form the surface to the inside. Because the cutting blade adopts the structure of the melted and clad alloy hardening layer in the utility model, the melted and clad alloy hardening layer and the cutting tool base body present a good metallurgy combination, thereby, the cutting blade is sharp and durable, without repeatedly blade grinding, and the melted and clad alloy hardening layer has no crack, the hardness is high, the surface is smooth, and the hardening layer is even and artistic. In addition, the laser melting and cladding processing cost is not high. The utility model can be compared with the foreign products in performance completely, but the price is much lower. The utility model is a cutting tool with laser melting and cladding alloy layer cutting blade, the performance is excellent, the utility model is convenient and practical, the quality is high and the price is inexpensive, the utility model can be used as the cutting tool in printing and tanning industries, the cutting tool used for clothes scissoring, the military cutting tool, the agricultural chopper or reaping hook, and the kitchen cutting tool, the dinner knife, the fruit cutting tool, the scissors, the paper cutting knife, and the art designing knife in daily life, the cutting tool used among herdsmen, and the cutting tool used in the custom of the minorities.
Description
1, technical field:
The utility model is a kind of cutter, and particularly a kind of cutter with cladding alloy layer cutting edge belongs to the renovation technique of cutter.
2, background technology:
Cutter is an indispensable instrument in all trades and professions and the people's lives, as ripper with cutter, process hides, cloth-cutting with cutter, military cutter, Kitchen knife, table knife, fruit knife, scissors, paper knife, cutter, herd civil knifes, the minority people and count custom with various cutters such as cutter, chopper, reaping hooks, cutter is various in style, of many uses, demand is very big.But the cutter ubiquity of the present market supply of China not high, the short-life problem of cutting edge hardness, needs often to whet a knife.At present, occurred a kind of " fool's cutter " abroad, it is that cutting edge with cutter carries out spray treatment, and cutting edge hardness height need not repeat sharpening, and is durable in use, though price is more expensive, also the cutter manufacturing industry to China constitutes a threat to.Particularly China enters after the WTO, and this threat more very.
3, summary of the invention:
The purpose of this utility model be to consider the problems referred to above and provide a kind of not only cutting edge sharp, durable, do not need sharpening repeatedly, and flawless, hardness height, any surface finish, the even cutter of band cladding alloy layer cutting edge attractive in appearance.
Structural representation of the present utility model as shown in Figure 1, include tool matrix (1), blade (2), wherein blade (2) from outward appearance to inner essence includes cladding alloy-layer (21), hardened layer (22) and matrix for having the sclerosis cutting edge of cladding alloy hardened layer at the position of blade (2).
The width of the cladding alloy hardened layer of above-mentioned blade (2) is 5～6mm, and thickness is 0.02～0.08mm.
Also can include tempering layer (23) between above-mentioned hardened layer (22) and the matrix.
The composition of above-mentioned cladding alloy-layer (21) is the alloy based on precoating coating, and thickness is 0.02～0.04mm.
The quench hardened case that above-mentioned hardened layer (22) includes the alloying layer that joins with cladding alloy-layer (21), joins with tempering layer (23).
The martensitic carbide that mainly is organized as refinement of above-mentioned hardened layer (22).
Above-mentioned tempering layer (23) be organized as sorbite and carbide.
Blade in the utility model is because employing has the structure of cladding alloy hardened layer, cladding alloy hardened layer is excellent metallurgical with tool matrix and combines, therefore, its not only make cutting edge sharp, durable, do not need sharpening repeatedly, and cladding alloy hardened layer flawless, hardness height, any surface finish, evenly attractive in appearance.In addition, the cost of Laser Cladding Treatment is not high.The utility model can match in excellence or beauty with external like product on performance fully, but price is much lower.The utility model is a kind of function admirable, convenient and practical, the cutter of inexpensive band cladding alloy layer cutting edge, can be widely used as the cutter of industries such as printing, process hides, the cloth-cutting cutter, military cutter, agricultural chopper, reaping hook, and kitchen cutter, table knife, fruit knife, scissors, paper knife, the cutter used of daily life, herd civil knifes, the minority people and count custom with cutter etc.
4, description of drawings:
Fig. 1 is a structural representation of the present utility model.
5, the specific embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include tool matrix (1), blade (2), in the present embodiment, the kitchen cutter that it is used for daily life, the material of tool matrix (1) is 3Cr13, cutter is when producing, earlier through modified or quenching preliminary treatment, and,, use CO again in the position precoating skim carbide alloy superfines of blade (2) through after cleaning
2The quick scanning and irradiation of laser then forms the cladding alloy hardened layer of high-wearing feature at the position of blade (2).The width of this cladding alloy hardened layer is 5～6mm, and thickness is 0.02～0.08mm.Cladding layer is blocked up easily to crack on the contrary, and average hardness can reach HV1078/HRC70.And the used material 3Cr13 of tool matrix (1) only is HV604/HRC55 at the average hardness of quenching attitude.Through the abrasion contrast test, the weightless mean value 5.97mg of test specimen, and the used weightless mean value of material 3Cr13 of tool matrix (1) is 14.7mg, this shows that its wearability has improved 2.5 times.Cladding alloy hardened layer flawless, hardness height, any surface finish, evenly attractive in appearance, and cladding alloy hardened layer is excellent metallurgical with tool matrix (1) and combines, and it has strengthened hardness, wearability and the sharpness of cutter.
Because the heat affecting of laser scanning, the cutter that cladding is handled through the laser thin layer, cross section from blade (2), Metallographic Analysis shows, from outward appearance to inner essence include cladding alloy-layer (21), hardened layer (22), tempering layer (23) and matrix at the position of blade (2), do not have tempering layer (23) when wherein the cutter preliminary treatment is for quenched and tempered state.The composition of above-mentioned cladding alloy-layer (21) is the alloy based on precoating coating, and thickness is 0.02～0.04mm, and hardness is HV990～1300, and cladding alloy-layer (21) is the key that improves cutting edge roundness hardness and wearability.The quench hardened case that above-mentioned hardened layer (22) includes the alloying layer that joins with cladding alloy-layer (21), joins with tempering layer (23).The martensitic carbide that mainly is organized as refinement of above-mentioned hardened layer (22), the hardness gradient of hardened layer (22) is mild, and it plays a supportive role to cladding layer.Above-mentioned tempering layer (23) be organized as sorbite and carbide.The about 0.2mm of width of tempering layer (23) (cutter preliminary treatment for quenched and tempered state time do not have tempering band), hardness is about HV440～470.Tempering layer (23) helps keeping the toughness of cutting edge.Impact flexibility when using to improve cutter.
