Abstract
The utility model discloses a combined blade by carbon steel and alloy tool steel, which belongs to cutter. The utility is characterized in that a flat flute is positioned on the carbon steel blade body, and a tool steel blade edge body is embedded in the flat flute. The tool steel is alloy tool steel, which is processed by heat rolling mill at first to make the blade body and blade edge body are integrated together, and then processed by heat process and metal machining. Therefore, for this blade, only the blade edge body is tool steel, which is sharp enough for meeting the usage need, but the blade body is carbon steel which can be easy for drilling or taping. The utility model is convenient for installation and can reduce the usage quantity on tool steel, in order to reduce the production cost.
Description
Technical field
The utility model belongs to cutter, especially relates to a kind of industrial cutter.
Background technology
The blade that uses in existing forestry, papermaking, printing, the metallurgy industry is generally all steel blade, this all steel blade adopts high carbon tool steel or alloy tool steel manufacturing, increased the consumption of tool steel on the one hand, increased cost, on the other hand after the tool steel Quenching Treatment, boring, tapping is very difficult, increased working strength of workers, and work efficiency is low.
Summary of the invention
The purpose of this utility model is to propose a kind of carbon steel/alloy tool steel composite blade, when guaranteeing edge of a knife instructions for use, reduce the use amount of tool steel significantly, reduce the consumption of tool steel, reduce cost, the knife back of blade is partly holed, tapping is all very convenient, blade is easy to install, reduce labour intensity, improve work efficiency.
The purpose of this utility model is achieved like this: a kind of carbon steel/alloy tool steel composite blade, it is characterized in that on the blade body of carbon steel, offering plane groove, the blade bodies of the tool steel of setting-in bar shaped in this plane groove, this tool steel is alloy tool steel, boring bolt is fixedlyed connected with the blade body after the section differential annealing of the two ends of blade bodies earlier, then through high-temperature calcination, hot rolling makes blade body and blade bodies form an integral body through hot-rolling mill, and then through Overheating Treatment, metalworking becomes blade, and it is tool steel that this blade has only blade bodies, and the edge of a knife is sharp, satisfy instructions for use, and the blade body is a carbon steel, is easy to boring on the blade body, tapping, easy for installation, and reduced the use amount of tool steel effectively, reduced production cost.
The carbon steel that the utility model proposes/alloy tool steel composite blade, rational in infrastructure, use reliably, both reduced the use amount of tool steel significantly, reduced cost, be easy to boring, tapping, easy for installation again, improved work efficiency.
Now the carbon steel of in conjunction with the accompanying drawings and embodiments the utility model being carried/alloy tool steel composite blade is described further.
Description of drawings
Fig. 1 is that the master of carbon steel/alloy tool steel composite blade of proposing of the utility model looks schematic diagram.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
Among Fig. 1: 1, blade body 2, blade bodies
Among Fig. 2: 3, plane groove
The specific embodiment
From Fig. 1, among Fig. 2 as can be seen: a kind of carbon steel/alloy tool steel composite blade, it is characterized in that on the blade body 1 of carbon steel, offering plane groove 3, the blade bodies 2 of the tool steel of setting-in bar shaped in this plane groove 3, this tool steel is alloy tool steel, boring bolt is fixedlyed connected with blade body 1 after the section differential annealing of the two ends of blade bodies 2 earlier, then through high-temperature calcination, hot rolling makes blade body 1 and blade bodies 2 form an integral body through hot-rolling mill, and then through Overheating Treatment, metalworking becomes blade, and this blade has only blade bodies 2 to be tool steel, and the edge of a knife is sharp, satisfy instructions for use, and blade body 1 is a carbon steel; On blade body 1, be easy to boring, tapping, easy for installation, and reduced the use amount of tool steel effectively, reduced production cost.
