Abstract
The utility model discloses a tool blank of a steel-inserted mechanical tool blade, which is mainly composed of a high-carbon alloy tool steel which is used as a blade edge, and a low-carbon steel which is used as a blade body. The tool blank is characterized in that an additional low-carbon steel element is welded on the low-carbon steel of the blade body outside the high-carbon alloy tool steel of the blade edge. The design of the utility model is artful, and the structure is reasonable. The welding difficulty is decreased, the welding procedure is simplified, and the welding quality is improved. Furthermore, after rolling, the composite quality is ensured. The ordinary arc welding is used for replacing the argon arc or other kinds of protective gas welding methods. At the same time, the energy consumption, working hours and the equipment investment of preheating and tempering are saved. Therefore, the production cost is reduced. The utility model is worth popularizing.
Description
The utility model relates to a kind of cutter embryo, particularly relates on the outer mild steel of using as cutter hub of a kind of high carbon alloy tool steel of using as blade the cutter embryo that also solid welding has the adapter of a mild steel.
At present, the cutter embryo of existing edge steel mechanical bit, be high carbon alloy tool steel or the high-speed steel that to use as blade earlier, the surface finish that reaches the mild steel of using as cutter hub is clean, make it not have grease and rust staining, then both are assembled into the cutter embryo of definite shape, and with both all seam crossings electric welding through weldings, making it to seal with air tight purpose is to make the cutter embryo heat the surface that all need weld at high temperature furnace, keeps clean with not oxidized.Reach uniform temperature and after rolling mill was rolling, bimetallic cutter embryo was combined into the blank blade under the effect of high temperature, high pressure when the cutter embryo like this.Problem and shortcoming that prior art exists are as follows: because high-carbon steel steel alloy and low-carbon alloy steel directly weld, so must take operations such as weld preheating and postwelding tempering.But also must adopt argon arc welding or the welding of other protective gas.In addition, individual carbon alloy steel is because directly, weld must be as cast condition and influence cutting edge strength.The possibility that weld crack appears in the while commissure is also bigger, will influence composite quality so again.
The purpose of this utility model provides a kind of, can effectively overcome above-mentioned defective, and cutting edge steel local as cast condition do not occur because of welding, guarantees the cutter embryo of the edge steel mechanical bit of cutting edge strength.
The technical solution of the utility model is, a kind of cutter embryo of inlaying the steel mechanical bit, mainly form by the high carbon alloy tool steel of using as blade with as the mild steel that cutter hub is used, its characteristics are: on the outer mild steel of using as cutter hub of the high carbon alloy tool steel of using as blade also solid welding the adapter of one mild steel is arranged.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, and is rational in infrastructure, reduced the welding difficulty, improved welding quality, guarantees that the crack does not appear in weld seam, thereby guarantee the composite quality after rolling.Also simplified welding sequence, replaced argon arc or the welding of other protective gas, saved simultaneously owing to preheating and required energy consumption, man-hour and the equipment investment of tempering, thereby reduced production cost, the tool promotional value with the common electrical arc-welding.Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a sectional structure schematic diagram of the present utility model.
Among the figure, this edge steel mechanical bit is made up of the mild steel 2 of using as cutter hub with high carbon alloy tool steel 1, one as blade and the adapter 3 of a mild steel.The three is welded into an integral body with the common electrical arc-welding, because of the adapter 3 of mild steel is to be welded on the outer mild steel of using as cutter hub 2 of the high carbon alloy tool steel used as blade 1, so all electric welding are only carried out between mild steel, thereby guaranteed the cutter embryo after rolling mill is rolling, the cutting edge strength of blank blade.
