Abstract
The invention provides a shield machine cutter which comprises a cutter body and a plurality of cutter edge bodies, wherein the cutter edge bodies are protruded at and surrounds the periphery of the cutter body; the height that the cutter edge bodies are protruded from the cutter body is less than 5mm. The shield machine cutter has the advantages that the cutting force is greatly enhanced due to the design of the cutter edge bodies; meanwhile, by virtue of combination of the special shape design of the cutter body and the connection design of the cutter edge bodies, the structure strength of the cutter is enhanced, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of shield machine cutter, belong to cutting technology field.
Background technology
Existing shield machine cutter form of structure is varied, and the design of its architectural feature is studied along the structural strength direction of higher cutting force and Geng Gao nothing but.Structure design be rationally whether the key index of judgement shield machine ability to work.
Summary of the invention
The invention provides a kind of shield machine cutter, smear metal power is stronger, and structural strength is higher.
For solving above technical problem, the invention provides following technical scheme: a kind of shield machine cutter, described shield machine cutter comprises cutter body and protrusion and around the cutter rib body of cutter body surrounding, described cutter rib body is several, and the height that described cutter rib body protrudes cutter body is less than 5mm.
Further, the both sides, lateral section of described cutter rib body are outer convex.
Further, fillet has been led in the junction of described cutter body and cutter rib body.
Further, the lateral section of described cutter body is up-narrow and down-wide.
Further, the normal section of described cutter body is trapezoidal.
Further, the material of described cutter is wolfram steel.
This shield machine cutter the present invention relates to, by the design of cutter rib body, its cutting force strengthens greatly, and meanwhile, the design of the special shape of this cutter body, in conjunction with the connection design of cutter rib body, increases the structural strength of this cutter, and extend application life.
Accompanying drawing explanation
Fig. 1 is shield machine cutter elevation of the present invention;
Fig. 2 is shield machine cutter cutter rib of the present invention side view.
The specific embodiment
As Figure 1-Figure 2, a kind of shield machine cutter, described shield machine cutter comprises cutter body 1 and protrudes and around the cutter rib body 2 of cutter body surrounding, described cutter rib body 2 be several, the height of described cutter rib body 2 protrusion cutter bodies is less than 5mm.
The both sides, lateral section of described cutter rib body are outer convex 21.
Described cutter body 1 has been led fillet with the junction of cutter rib body 2.
The lateral section of described cutter body 1 is up-narrow and down-wide.
The normal section of described cutter body 1 is trapezoidal.
The material of cutter is wolfram steel.Wolfram steel is a kind of hard alloy steel of tungstenic, and its hardness is high, although its toughness is poor, is particularly useful in this plant equipment of working continuously.Its cost is lower with respect to diamond price, so cost performance is higher.
The specific embodiment of the present invention does not form the restriction to the application's scope; every within the spirit and principle of the present invention design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection scope of the present invention.
