Embodiment Construction
[0010] In the present invention, the blade of special high-alloy steel 1 and the body of low-carbon steel 2 are compounded by casting or high temperature and high pressure.
[0011] exist figure 1 In the shown embodiment, the blade of special high-alloy steel 1 is compounded on the cutter body of low-carbon steel 2, and the composite position is that the blade of special high-alloy steel 1 is embedded in the cutter body of low-carbon steel 2 to form the cutting working part .exist figure 1 In the shown embodiment, special high alloy steel 1 is made of carbon C0.55-0.85, silicon Si0.70-1.20, chromium Cr7.50-9.50, tungsten W1.00-1.80, molybdenum Mo1.50-2.20, vanadium 0.20- 0.80, manganese Mn≤0.50 after smelting; low carbon steel 2 is smelted after carbon 0.12-0.20, manganese Mn0.40-0.70.

The invention relates to a wood-working mechanical cutting blade which is characterized in that a cutting edge and a cutter body of the cutter blade are formed in a mode that special high alloy steel is compounded with low-carbon steel, wherein the special high ally steel comprises the following elements and ratio of the elements: 0.55 to 0.85 of carbon C, 0.70 to 1.20 of silicon Si, 7.50 to 9.50 of chromium Cr, 1.00 to 1.80 of tungsten W, 1.50 to 2.20 of molybdenum Mo, 0.20 to 0.80 of vanadium V and less than or equal to 0.50 of manganese Mn; and the low carbon steel comprises the following elements and ratio of the elements: 0.12 to 0.20 of carbon C and 0.40 to 0.70 of manganese Mn. Compared with the common alloy steel wood-working mechanical cutting blade, the wood-working mechanical cutting blade which is formed in a mode that the special high alloy steel is compounded with the low-carbon steel has lower cost and has the cutting edge with higher strength and hardness, and thus, not only are national scarce metals such as chromium, tungsten, molybdenum, vanadium and the like saved, but also the working efficiency is improved.
Description
Technical field: [0001] The present invention relates to woodworking machinery blades. Background technique: [0002] At present, known woodworking machinery blades are made of general high-alloy steel. [0003] Since the working part of the woodworking machinery blade is the blade, and the hardness of the blade is usually between HRC60-62, the blade must be made of high-alloy steel, so that the blade body is also made of high-alloy steel. The ratio of the effectively used blade to the blade body is 15%. As far as 85% is concerned, the high-alloy steel used in the 85% cutter body can be regarded as a waste. [0004] In addition, since the alloying elements and their proportions of general high-alloy steels have not been invented specifically for woodworking machine blades, there is also the problem of low utilization efficiency of alloy steels when general high-alloy steels are used for woodworking machine blades. Invention content: [0005] In order to overcome the abov...
