Abstract
The invention relates to a high-strength shield tunneling machine cutter. The high-strength shield tunneling machine cutter comprises a hilt and a cutter body; the bottom surface of the cutter body is welded to the top of the hilt; a plurality of beads are uniformly arranged on the cutter body; the beads are uniformly and obliquely distributed on a side surface and an upper surface of the cutter body; the cross section of each bead is trapezoidal; the heights of each two adjacent beads are different; and a step-shaped mounting hole is formed in the front surface of the hilt. The high-strength shield tunneling machine cutter has the advantages that the structure is simple; the cutter is convenient to produce and manufacture and low in cost; the cutter body has a bead structure and is cuboid-shaped, the strength of the cutter is improved, and the service life of the cutter is prolonged; the beads exceed the surface of the cutter body so that cutting efficiency can be improved; owing to reasonable projection height, the strength of the cutter is guaranteed; a force which is stressed by the cutter body is transferred to the hilt and then is dispersed to the lower end of the hilt from the upper end of the hilt; tolerance of the cutter is improved; and because the cutter is made of a hard alloy material, the strength is high, the cutter is durable, and the service life of the cutter is prolonged.
Description
Technical field
The present invention relates to and 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, solves the problem that existing tool strength 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, described fin is 120 ° ~ 160 ° relative to the angle of inclination of the bottom surface of described cutter body, described in every bar, the cross section of fin is trapezoidal, the height of two adjacent described fins is different, the front of described handle of a knife is provided with step-like installing hole.
Further, described fin protrudes the height on described cutter body surface is 3 ~ 6mm.
Further, described fin protrudes the minimum thickness on described cutter body surface is 2mm.
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.
Further, described cutter body is made up of hard alloy steel.
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; Fin exceeds cutter body surface and is conducive to improving cutting efficiency, and rational protrusion height can ensure the intensity of cutter; 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, improves the holding capacity of cutter; The Material Strength of carbide alloy is high, makes cutter more durable, improves cutter life.
Accompanying drawing explanation
Fig. 1 is for being structural representation of the present invention;
In figure 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, a kind of shield machine cutter of high strength, comprise handle of a knife 1, cutter body 2, 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, described cutter body 2 is evenly provided with many fins 3, 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, described fin 3 is 120 ° ~ 160 ° relative to the angle of inclination of the bottom surface of described cutter body 2, described in every bar, the cross section of fin 3 is trapezoidal, the height of adjacent two described fins 3 is different, the front of described handle of a knife 1 is provided with step-like installing hole 4.The height that described fin 3 protrudes described cutter body 2 surface is 3 ~ 6mm.The minimum thickness that described fin 3 protrudes described cutter body 2 surface is 2mm.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.Described cutter body 2 is made up of hard alloy steel.
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.
Structure of the present invention 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; Fin exceeds cutter body surface and is conducive to improving cutting efficiency, and rational protrusion height can ensure the intensity of cutter; 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, improves the holding capacity of cutter; The Material Strength of carbide alloy is high, makes cutter more durable, improves cutter life.
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.
