Description
Technical Field
The invention relates to a construction tool, in particular to a dust-free cutter for cutting rock wool.
Background
Rock wool is a novel heat-insulating fireproof material, and is widely used for equipment such as outer walls of modern buildings, industrial equipment, pipelines, kilns and the like, and is produced by melting, wire making, bonding and slitting natural rock.
The prior art is mainly divided into straight cutting edges, for example, the invention with publication number of CN207478745U discloses an improved cutting edge crusher blade for rock wool, which comprises a plurality of straight teeth which are relatively large in distance and are inlaid with alloy blades, but the straight teeth and the rock wool can generate relatively violent collision, a large amount of fibers and dust are generated, the environment and the body of an operator are greatly threatened, and the cutting section is uneven.
The invention patent with publication number 106493761A discloses an alloy-inlaid dust-free rock wool cutting knife, which comprises a knife body and a knife edge, wherein the knife body is circular, the knife edge is in an arc section shape, the knife edge is uniformly welded on the outer side surface of the knife body to form a complete circumferential knife edge, and a silencing groove is formed at the outer round end of the knife body. The rock wool cutting knife has the beneficial effects that the problems that the existing rock wool cutting knife has a large dust amount and large production noise when cutting rock wool can be solved, but the rock wool cutting knife belongs to a toothless knife due to the continuous circular arc-shaped knife edge, and the defects of tilting, deformation, bonding cracking and the like are easily formed at the cutting section in the cutting process due to the extrusion cutting of the toothless knife.
Disclosure of Invention
The invention aims to overcome the defects of the two existing cutters, develop the advantages of the two existing cutters, and simultaneously, the cutter has enough service life, and meanwhile, the near continuous cutting of the cutting edge leads to extremely small dust quantity and better rock wool cutting section. The technical scheme adopted by the invention is as follows:
a dustless circular knife for rock wool cutting, is including being annular blade disc, a plurality of evenly sets firmly the cutter tooth of carbide material of blade disc circumference outer fringe, its characterized in that: the cutter teeth are mutually abutted left and right to form a circular ring shape, each cutter tooth comprises a tooth body, the tooth body is outwards thinned gradually to form a tooth edge, a quarter circular notch is formed in the two ends of the tooth edge, a semicircular notch is formed in the middle of the tooth edge, and two adjacent quarter circular notches are spliced to form a notch with the same shape as the semicircular notch. The notches on all the tooth edges form uniform intermittent arc notches, and due to the design of the notches, the feeding speed of rock wool cutting is improved, and the cutting efficiency of the rock wool is further improved. The design of the tooth edge and the semicircular notch of the thinning can reduce dust generation and dust pollution in the rock wool cutting process.
Preferably, an embedded groove extending outwards is formed in the middle of the inner end of the tooth body, the tooth body is embedded in the circumferential outer edge of the cutterhead through the embedded groove and then welded with the cutterhead, the depth of the embedded groove is 1/8-1/4 of the width of the outline of the tooth blade, and the width of the embedded groove corresponds to the thickness of the cutterhead. The embedded and welded mode can further increase the strength and prolong the service life of the cutter.
Preferably, the intersections of the quarter-round notch and the semicircular notch with the outer ends of the tooth blades are transited through a blunt arc. The transition mode has a protective effect on the sharp cutting edge, reduces the damage risk of the cutting edge of the cutter, and prolongs the service life of the cutter; at the same time, during the cutting process, the near-continuous cutting can obtain a polished cutting section.
Preferably, the radius of the quarter-circle notch and the radius of the semicircle notch are equal to each other and less than or equal to 1/4 of the width of the tooth edge profile.
Preferably, the cutting edge angle of the tooth edge is 30-50 degrees.
Preferably, the included angle of the two side end planes of the tooth body is 2-15 degrees.
Preferably, the cutterhead is uniformly provided with a plurality of silencing grooves.
Compared with the prior art, the invention has high feeding speed, reduces the generation of dust in the rock wool cutting process, reduces dust pollution and can obtain a smooth cutting section.

Detailed Description
Referring to the drawings, a dust-free circular knife for cutting rock wool comprises a circular cutterhead 1, 100 cutter teeth 2 which are uniformly fixed on the periphery of the cutterhead 1 and made of hard alloy materials, wherein the cutter teeth 2 are mutually abutted left and right to form a circular ring, each cutter tooth 2 comprises a tooth body 21, the tooth bodies 21 are gradually thinned outwards to form tooth edges 22, a quarter circular notch 221 is formed in two ends of each tooth edge 22, a semicircular notch 222 is formed in the middle of each tooth edge 22, and two adjacent quarter circular notches 221 are spliced into notches with the same shape as the semicircular notch 222. The tooth body 21 is embedded in the peripheral outer edge of the cutterhead 1 through the embedded groove 23, and then welded with the cutterhead, the depth g of the embedded groove is 1/6 of the outline width a of the tooth edge, and the width h of the embedded groove corresponds to the thickness of the cutterhead 1, so that transition fit or interference fit can be realized. The intersections of the quarter-round notch 221 and the half-round notch 222 with the outer ends of the tooth edges 22 are transitioned by a blunt arc 223. The radius of the quarter-round notch 221 and the half-round notch 222 are equal and equal to 1/4 of the tooth edge profile width a. The edge angle f of the tooth edge 22 is 45 °. Since the number of the cutter teeth 2 is 100, the included angle d DEG of the planes of the two side ends of the tooth body 21 is 3.6 DEG after equally dividing 360-degree circumference. 10 silencing grooves 11 are uniformly formed in the cutter head. The number of cutter teeth 2 between two adjacent silencing grooves is 10.
