Abstract
A diamond bora grinding block comprises a metal matrix and a diamond grinding head, wherein the metal matrix is provided with an attachment surface; the diamond grinding head is attached on the attachment surface of the metal matrix; two wedge-shaped grooves which are symmetrically distributed at two sides of the metal matrix by taking the center line of the metal matrix as a center are formed on the attachment surface of the metal matrix; and the wedge-shaped grooves extend approximately along the length direction of the metal matrix. The diamond bora grinding block has the advantages as follows: the structure is simple, the utilization rate of the diamond material is high, the attachment of the diamond grinding head is firm, and the like.
Description
Technical field
The utility model relates to the diamond tool field, relates in particular to a kind of diamond bora abrading block.
Background technology
The diamond bora abrading block is widely used in field of stone processing; The Bradley abrading block is made up of metallic matrix and the diamond grinding head that is attached on the metallic matrix usually, and in order to increase the adhesive force of diamond grinding head, meeting is offered dovetail groove one at the middle part of the attachment surface of metallic matrix usually; In order to make adhesive force reach certain requirement; Dovetail groove needs enough big, in dovetail groove, have a large amount of diamond grinding head materials, and these diamond grinding head materials is unserviceable; So just cause the waste of diamond grinding head material, increase the cost of Bradley abrading block.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, provide a kind of simple in structure, the diamond utilization rate high and the diamond bora abrading block of diamond grinding head adhesion-tight.
The purpose of the utility model realizes through following technical scheme:
A kind of diamond bora abrading block; Comprise metallic matrix and be attached to the diamond grinding head on the metallic matrix attachment surface with attachment surface; It is characterized in that: it is the wedge-shaped slot that the center is symmetrically distributed in metallic matrix dual-side place with the metallic matrix center line that the attachment surface of metallic matrix is formed with twice, and said wedge-shaped slot roughly extends along the metallic matrix length direction.
Further, said wedge-shaped slot extends with the direction straight line that departs from 0.5 °-1.5 ° of metallic matrix center lines, and the centrifugal force direction of distance when metallic matrix is worked between the two said wedge-shaped slots dwindled gradually.
Further, said wedge-shaped slot is made up of the horizontal cell wall and the inclination cell wall that intersect, and said horizontal cell wall extends to the side of metallic matrix, and said inclination cell wall extends to the attachment surface of metallic matrix.
Further, the angle of the attachment surface of the angle of said horizontal cell wall and inclination cell wall and/or inclination cell wall and metallic matrix is an arc chord angle.
Further, the attachment surface of said metallic matrix is an arcwall face.
The utlity model has following beneficial effect:
Attachment surface at metallic matrix forms the twice wedge-shaped slot, compares with the dovetail groove of prior art, and the diamond that wedge-shaped slot holds is less than dovetail groove far away; And enough adhesive force can be provided, make diamond grinding head difficult drop-off or loosening, according to the consumption mechanism of Bradley abrading block; Wedge-shaped slot is arranged at metallic matrix dual-side place, after the Bradley abrading block is scrapped, only has a small amount of diamond in the wedge-shaped slot; Effectively improve the utilization rate of diamond, reduced the cost of manufacture of Bradley abrading block; Wedge-shaped slot extends with the direction straight line that departs from 0.5 °-1.5 ° of metallic matrix center lines; The centrifugal force direction of distance when metallic matrix is worked between the two said wedge-shaped slots dwindled gradually; Make the Bradley abrading block in the course of the work; Two wedge-shaped slots form certain chucking power to diamond grinding head under the action of the centrifugal, thereby improve the firmness between metallic matrix and the diamond grinding head; The angle of the attachment surface of the angle of horizontal cell wall and inclination cell wall and/or inclination cell wall and metallic matrix is set to arc chord angle; The Bradley abrading block is in the hot pressed sintering process; Arc chord angle helps flowing of diamond; Prevent to exist between diamond grinding head and the wedge-shaped slot gap or produce bubble, thereby improve the quality of Bradley abrading block; The attachment surface of metallic matrix is set to arcwall face, meets the consumption mechanism of Bradley abrading block, improves the utilization rate of diamond.

The specific embodiment
With reference to Fig. 1, Fig. 2 and shown in Figure 3; A kind of diamond bora abrading block; Comprise metallic matrix 1 and be attached to the diamond grinding head 2 on metallic matrix 1 attachment surface with arc attachment surface; It is the wedge-shaped slot 11 that the center is symmetrically distributed in metallic matrix 1 dual-side place with metallic matrix 1 center line that the attachment surface of metallic matrix 1 is formed with twice, and wedge-shaped slot extends with the direction straight line that departs from 1 ° of metallic matrix center line, and the centrifugal force direction when making distance between two wedge-shaped slots 11 along metallic matrix 1 work is dwindled gradually; Wedge-shaped slot 11 is made up of horizontal cell wall that intersects 111 and inclination cell wall 112; Horizontal cell wall 111 extends to the side of metallic matrix 1, and inclination cell wall 112 extends to the attachment surface of metallic matrix 1, and the angle of horizontal cell wall 111 and inclination cell wall 112 and inclination cell wall 112 are arc chord angle with the angle of the attachment surface of metallic matrix 1.
The above; Be merely the preferred embodiment of the utility model; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
