Abstract

The utility model discloses a cutting saw blade which adopts the scheme that abradant bodies are arranged on the end face of a base body; abradant bodies positioned on the same circumference form abradant rings; an annular scrap discharging clearance is formed between every two adjacent abradant rings; during the cutting processing, scraps falling off from a workpiece can be accommodated in the scrap discharging clearances and discharged along with the rotation of the base body; during the process that the base body drives the scraps to rotate, the scraps are positioned in the scrap discharging clearances and cannot be contacted with the processing surface of the workpiece, so that scraps falling off from the workpiece can be discharged conveniently, the contact between the scraps and the processing surface and the scratch of the scraps to the processing surface are reduced, therefore, the cutting processing precision is improved.

Description

A kind of cast-cutting saw slice

Technical field

The utility model relates to a kind of cast-cutting saw slice.

Background technology

At present, the grinding layer arranged on the end face of commercially available cast-cutting saw slice by discoid matrix and matrix forms, wherein grinding layer is the annulate lamella body extended along the circular periphery of matrix, adopt this cast-cutting saw slice in high-speed machining process, the scrap broken away from from workpiece can be extruded under the squeezing action of grinding layer from corresponding grooving, and in the process of extruding at scrap, this part scrap can scratch manufactured machined surface, machining accuracy with suitable workpiece reduces, and the workpiece of even suitably processing is scrapped.Can produce higher heat between abrasive material and workpiece simultaneously, these heats distribute slower in the abrasive material inside of cast-cutting saw slice, thereby cause the too much problem of cast-cutting saw slice internal heat, the distortion so that cast-cutting saw slice easily is distorted under the heat effects of these savings, and cutting blade is when being distorted distortion, the size of cutting blade self also can change accordingly, causes the machining accuracy of cutting blade and dependability to reduce.

The utility model content

The purpose of this utility model is to provide a kind of cast-cutting saw slice of scrap to the machined surface damage that reduce.

In order to realize above purpose, the technical scheme of cast-cutting saw slice of the present utility model is as follows:

A kind of cast-cutting saw slice, comprise discoid matrix, on the end face of described matrix, convex with along abrading-body circumferential spaced apart or that extend, abrading-body on same circumference forms the abrasive material circle, described abrasive material circle has at least two and upwards spaced apart in the footpath of matrix, has the burr and chip clearance of the annular of circumferentially extending along matrix between adjacent two abrasive material circles.

Described abrading-body edge on the end face of matrix is circumferentially spaced apart, the cylinder that each abrading-body is cylindric or prism-shaped.

Described abrasive material circle makes progress and is sized to the height dimension of abrasive material circle in base shaft, and in adjacent two abrasive material circles, the height dimension of outer abrasive material circle is more than or equal to the height dimension of inner abrasive material circle.

The height of described each abrasive material circle reduces from outside to inside gradually.

Height dimension in outermost abrasive material circle in described each abrasive material circle is not less than the twice of the height dimension of the most inboard abrasive material circle.

The utility model is provided with abrading-body on the end face of matrix, abrading-body on same circumference forms the abrasive material circle, and there is annular burr and chip clearance between adjacent two abrasive material circles, in cutting process, the scrap come off from workpiece can be housed in burr and chip clearance and be taken out of with the rotation of matrix, at matrix, drive in the process of scrap rotation, scrap is in burr and chip clearance and can not contact with the machined surface on workpiece, thereby be convenient to discharge the scrap come off on workpiece, reduce the contact of scrap on machined surface and to the scuffing effect of machined surface, so that the precision of machining to be provided.The cutting heat produced between abrasive material and workpiece can circumferentially distribute along matrix simultaneously in burr and chip clearance, especially in the situation that use cooling medium, cooling medium can carry out fully cooling under the guide effect of burr and chip clearance to abrasive material, guarantee that in abrasive material, the heat on each abrasive material circle all can be dissipated, therefore the utility model has improved the radiating efficiency of abrasive material in the cutting process, has guaranteed reliability and the machining accuracy of machining.

Fig. 2 is that the A-A of Fig. 1 is to cutaway view;

Fig. 3 is the structural representation of cast-cutting saw slice in embodiment 2 of the present utility model.

The specific embodiment

The embodiment 1 of cast-cutting saw slice of the present utility model: as depicted in figs. 1 and 2, this cast-cutting saw slice comprises that the abrading-body 1 be convexly equipped with on the two ends end face of discoid matrix 2 and matrix 2 forms, abrading-body on same circumference 1 is along circumferentially spaced apart and form annular abrasive material circle, there is the radially burr and chip clearance 5 radially extended along matrix 2 between each abrading-body 1 in same abrasive material circle, and the abrasive material circle has six, the circumferential burr and chip clearance 4 that there is the annular of circumferentially extending along matrix 2 between adjacent two abrasive material circles, what in the radially burr and chip clearance 5 on each abrasive material circle 1, have upwards distributes relatively in matrix 2 footpaths, what have upwards staggers mutually in matrix 2 footpaths, and each abrading-body 1 is the vertical columned abrasive material post on matrix 2 end faces that is located at, and the height of each abrading-body 1 equates.

In use, the block that each abrading-body 1 in this abrasive material is formed by diamond dust, cubic boron nitride dust, diamond particles or cubic boron nitride particle sintering, improved the sharpness of cutting blade to the present embodiment greatly.In abrasive material each abrading-body 1 be all soldering on matrix 2 both ends of the surface, high with the bond strength of matrix 2, avoided abrasive material in cutting process to come off.Simultaneously circumferentially burr and chip clearance 4 and radially burr and chip clearance 5 not only the heat in metal cutting produced in cutting process can be dissipated, and can get rid of the scrap produced in processing, prevented the problems such as workpiece scratch that scrap causes, improved operating efficiency.

The embodiment 2 of cast-cutting saw slice of the present utility model: as shown in Figure 3, the difference of the present embodiment and embodiment 1 is, in each abrasive material circle, the height of abrading-body 21 reduces from outside to inside gradually, so that in adjacent two abrasive material circles in outer abrasive material circle the height dimension of abrading-body 21 be more than or equal to the height dimension of abrading-body 21 in inner abrasive material circle, and the height dimension in the outermost abrasive material circle of matrix 22 is not less than the twice of the height dimension of the abrasive material circle the most inboard in matrix 22.

In the above-described embodiments, abrading-body is columned, and in other embodiments, abrading-body can be also prism-shaped or spherical crown shape or block block or the annular block of the opposite sex.

In the above-described embodiments, on each abrasive material circle, all offer radially burr and chip clearance, with make progress distribute heat and get rid of scrap of the footpath from abrasive material, in other embodiments, each abrasive material circle can be also at the annulate lamella body that matrix week makes progress continuous.
