Abstract
The invention relates to an abrasive cutoff wheel which comprises a central disk (2) and a plurality of abrasive segments (4) which subtend between themselves a straight bonding line (10) that slants inward along a predetermined disk direction of rotation (12) toward the wheel center of rotation 14, deviating from a tangent line. Seen in wheel sideview, the radially outer surface (18) of each abrasive segment (4) preferably also is straight and slants inward along the wheel direction of rotation (12) toward the wheel center of rotation (14), deviating from a tangent line.
Description
Technical field
The present invention relates to the abrasive cutoff-wheel that the aforementioned part of a kind of claim 1 limits, be used for cutting building material, particularly concrete, brick, watt, and be used to cut natural stone.
Background technology
Germany Patent document DE4424093C2 discloses a kind of abrasive cutoff-wheel of this form.It comprises center disk and sheet.Sheet is fixed to central disk circumference by laser weld non-dismountablely, and central disk circumference is continuous or is divided into lug again by circumferential clearance.The line of brace and center disk outline is with respect to center disk initial point arranged tangential or by two tangential rectilinear(-al)s that are used for each sheet accordingly, and described two lines are relative with the form on picture roof, and the angle between them is less than 180 °.
Summary of the invention
The objective of the invention is the improvement of abrasive cutoff-wheel.
This problem solves by the feature of claim 1 of the present invention.
In the present invention, shown in the side view of wheel, straight joint line of the relative formation of disk faying face with the sheet faying face that is fixed to the upper, the predetermined direction that described joint line rotates along wheel slopes inwardly towards the pivot of taking turns and departs from tangent line simultaneously.
The improved power that the invention provides on the joint line between abrasive segments and the center disk distributes, and allows higher load to act on the abrasive cutoff-wheel.The shearing of the substantial portion that the present invention will produce in dried cutting-off method (dry severing method) converts the compression stress on the joint line that is applied between abrasive segments and the center disk to.
Further feature of the present invention limits in the dependent claims.
In a preferred embodiment of the present invention, when at the side view of wheel when seeing, the radially-outer surface of each abrasive segments is straight, and every this outer surface formed on the disk direction of rotation towards the intilted surface line in center of wheel, departs from tangent line.Therefore, when abrasive cutoff-wheel is used for the first time, the workpiece that each frosted cutting blade has only a small part contact to be cut, thereby, between the operating period first time, allow mill abrasive segments automatically.
At least be made up of the inlaid material that comprises mosaic gold hard rock composition in the top area of abrasive segments, for instance, diamond composition sintering advances described inlaid material.Before abrasive cutoff-wheel was used for the first time, the diamond composition was outstanding from inlaid material, so, before or by using for the first time, for guarantee fund's hard rock composition can protrude on inlaid material, abrasive cutoff-wheel must be ground.
In another preferred implementation of the present invention, the surface line and the joint line of particular abrasive sheet always are parallel to each other.
In another preferred implementation of the present invention, center disk is provided with circumferential notch between all adjacent disk faying faces.Like this, the material that is worn from workpiece is easier to remove from the recess that is formed on the workpiece.
Below, by a preferred embodiment and accompanying drawings the present invention.
Description of drawings
Fig. 1 is the side view that the part of abrasive cutoff-wheel of the present invention is clipped.
The specific embodiment
Abrasive cutoff-wheel of the present invention as shown in Figure 1 comprises circular central disk 2 and a plurality of abrasive segments 4 in fact.Abrasive sheet 4 is preferably in that the whole periphery along center disk 2 evenly distributes on a plurality of straight (shown in the side view of wheel) disk faying faces 6 of equal number, and each sheet is equipped with the sheet faying face 8 of itself, sheet faying face 8 non-dismountablely for example by brazing connect, welding or Laser Processing be connected to a disk faying face 6.Center disk 2 preferably is formed from steel.
Abrasive cutoff-wheel of the present invention is carried out its cutting work in predetermined direction of rotation 12.
Each disk faying face 6 and be connected to and determined a straight joint line 10 (shown in the side view of wheel) between the sheet faying face 8 on it, this joint line slopes inwardly with respect to the pivot 14 of taking turns along the predetermined direction 12 of wheel rotation, that is, depart from the line that is tangential on the wheel pivot.The pivot 14 of trailing wheel is to the relative angle of departing from 90 ° that forms with described 6 of notional RADIAL at the center (in side view) of disk faying face 6.
When the side view of wheel is seen, the radially-outer surface 18 of each abrasive segments 4 is straight and defines a straight surface line 20 that when seeing in the side of wheel, surface line 20 tilts towards the pivot 14 of wheel, departs from tangent line on the direction of rotation of wheel.The surface line 20 and the joint line 10 of special abrasive segments 4 preferably are parallel to each other.
Between per two adjacent disk faying faces 6, center disk 2 is respectively arranged with circumferential notch 22,24.
In preferred implementation shown in Figure 1, circumferential notch 22 is different with 24 the degree of depth, and darker circumferential notch 24 and more shallow circumferential notch 22 are along circle alternate.The circumferential notch structure of different depth has reduced the danger that produces the crack on center disk.
In all of the embodiments of the present invention, subtend is removed basic material when circumferentially the gap, interval 26 between the abrasive segments 4 is convenient at the grinder part continuously.
