Description
Technical field
The present invention relates to the cutter field of mining machinery, particularly relate to a kind of shield machine cutter of high strength.
Background technology
Shield machine, as a kind of conventional excavating tools, has a wide range of applications in the work operations such as engineering construction, mining.Cutter, as the core component of shield machine, has very important effect.At present, the form of structure of existing shield machine cutter is of a great variety, but be generally from the cutting force improving cutter, the whether aspect such as fast and easy is installed studies, less to the structural research of cutter itself, and the design of this body structure of cutter is the key factor of cutter raising intensity.Existing cutter, common configuration intensity is lower, and application life is shorter, and cost is higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of shield machine cutter of high strength, overcomes the defect that conventional tool intensity is low, cutting force is low, financial cost is high.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of shield machine cutter of high strength, comprise handle of a knife, cutter body, described cutter body is cuboid, the bottom surface of described cutter body is welded on the top of described handle of a knife, described cutter body is evenly provided with many fins, on the side that many described fin uniform pitch are distributed in described cutter body and upper surface, described fin passes through chamfered transition in the junction of described cutter body, the angle of inclination of described fin is 120 ° ~ 160 °, the described fin face be fixed on described cutter body is flat surface, described fin is cambered surface away from the external surface of described cutter body, the front of described handle of a knife is provided with step-like installing hole.
The invention has the beneficial effects as follows: structure is simple, the manufacturing is convenient, cost is low, adopts the cutter body of fin structure design and cuboid, improves the intensity of cutter, extend application life.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described fin protrudes the height on described cutter body surface is 3 ~ 6mm.
The beneficial effect of above-mentioned further scheme is adopted to be: fin exceeds cutter body surface and is conducive to improving cutting efficiency, and rational protrusion height can ensure the intensity of cutter.
Further, the normal section of described handle of a knife is right-angled trapezium, and the right-angle side that the normal section of described handle of a knife is shorter welds with described cutter body.
Adopt the beneficial effect of above-mentioned further scheme to be: the power be subject to by cutter body is delivered on handle of a knife, then is distributed to the lower end of handle of a knife by the upper end of handle of a knife, improve the holding capacity of cutter.
Further, described cutter body is made up of hard alloy steel.
Adopt the beneficial effect of above-mentioned further scheme to be: the Material Strength of carbide alloy is high, makes cutter more durable, improve cutter life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the shield machine cutter of a kind of high strength of the present invention.
In accompanying drawing, the list of parts representated by each label is as follows:
1, handle of a knife, 2, cutter body, 3, fin, 4, installing hole.
Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, the shield machine cutter of a kind of high strength of the present invention, is arranged on shield machine, for fields such as engineering construction, mining excavations.The cutter body 2 comprise handle of a knife 1, being made up of hard alloy steel, described cutter body 2 is cuboid, the bottom surface of described cutter body 2 is welded on the top of described handle of a knife 1, the normal section of described handle of a knife 1 is right-angled trapezium, and the right-angle side that the normal section of described handle of a knife 1 is shorter welds with described cutter body 2.Handle of a knife 1 adopts welding manner to be connected with cutter body 2, is connected firmly, difficult drop-off, improves the intensity of cutter, extends cutting-tool's used life.Described cutter body 2 is evenly provided with many fins 3, and the height that described fin 3 protrudes described cutter body 2 surface is 3 ~ 6mm.On the side that many described fin 3 uniform pitch are distributed in described cutter body 2 and upper surface, described fin 3 passes through chamfered transition in the junction of described cutter body 2, adopt chamfered transition, make cutter transition mild, avoid cutter to collide with in process to damage, the angle of inclination of described fin 3 is 120 ° ~ 160 °, described fin 3 face be fixed on described cutter body 2 is flat surface, described fin 3 is cambered surface away from the external surface of described cutter body 2, and the front of described handle of a knife 1 is provided with step-like installing hole 4.
Its course of work is: by bolt through the installing hole 4 on handle of a knife 1 by Cutting tool installation manner on shield machine, install the work of rear shield machine carry its tools, cutter body 2 carries out work, the structure design of cutter body 2 improves the intensity of cutter, the cutting power of cutter in operation process is improved, improves operating efficiency.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
