Abstract

The utility model discloses a combined stone cutter mainly composed of a cutter body provided with central holes and a group of cutter heads; the cutter heads are embedded in cutter embedding gaps uniformly distributed at the periphery of the cutter body and are fixedly screwed to position by countersunk rivets. The utility model has the advantages of simple structure and firm and reliable embedding, which is especially suitable to be arranged on a stone cutting machine for cutting various stones; users can replace the cutter heads on the spot; the cutter body has long service life, and the combined cutter heads has wide use ranges. The utility model is a stone cutter with convenience and applicability, which can improve cutting efficiency and reduce use cost.

Description

Combined type stone material cutter

The utility model relates to the cutter of cutting stone material, specifically a kind of combined type stone material cutter, and it is particularly suitable for being installed on makita 4100NH and cuts various stone materials.

Common stone material cutter are one group of cutting cubes of welding on the uniform flat-top tooth of garden dise knife body periphery at present, when the cutter on being installed on cutting machine rotated, the cutting cube of periphery reached the purpose of cutting stone material with the continuous grinding on stone material of certain depth of cut.This cutter have higher operating efficiency, but can only and change cutting cube in special factory's welding.After cutter in use wore and tore, the user needed the cutter of the big heaviness of body are delivered to special factory, and old cutting cube is removed in heating earlier, and the new cutting cube of burn-oning again is time-consuming very inconvenient.And, be easy to cause that cutter hub is out of shape peaceful apical tooth brittle crack, so the service life of cutter hub is shorter because the flat-top tooth of cutter hub periphery repeatedly is heated to higher temperature.Chinese patent CN227196OY discloses utility model that a kind of name is called " inserted rock cutter ", cutter head has been embedded in the uniform snaps breach of cutter hub periphery and by steady pin fixes.Though the simple easy operating of this mosaic texture, the user can change cutter head on the spot, and cutter hub has been avoided the harm of local heat, can increase the service life, but snaps breach and cutter head only a side are provided with locating slot and the convex tendon that coincide mutually, can not prevent fully that cutter head is laterally loosening.The cylinder steady pin is difficult for close-fitting in the pin-and-hole of being made up of two semicircles, steady pin is easy to deviate to cause cutter head to come off, and directly the firm reliability of cutter head is inlayed in influence.

The purpose of this utility model, be propose on the basis of existing technology a kind of simple in structure, inlay solid and reliable, safety easy to use, the combined type stone material cutter that the cutter hub life-span is long, cutter head accommodation is extensive, it is particularly suitable for being installed on makita 4100NH and cuts various stone materials.

The purpose of this utility model is achieved by the following technical solution.

A kind of combined type stone material cutter, it mainly is made up of the cutter hub that has centre bore and one group of cutter head, the uniform snaps breach of cutter hub periphery, snaps breach both sides all are provided with many emboss pits, and a side is provided with the horizontal half slot that all there is tapering at two ends.Cutter head is combined by mosaic block and cutting cube.Both sides, mosaic block bottom are provided with many emboss pits that match with snaps breach both sides, one side is provided with the horizontal half slot that there is tapering at two ends, top is provided with the mounting groove of affixed cutting cube, the metal species cutting cube is welded in the mounting groove, unweldable nonmetal grinding segment class cutting cube edge folder is bonded in the mounting groove, make cutting cube and mosaic block firm be combined into cutter head.When the cutter hub periphery is inlayed cutter head, the recess of the high spot of both sides, cutter head bottom emboss pit being aimed at snaps breach both sides emboss pit inserts the snaps breach, sunk head rivet is pierced into the two ends of being made up of two half slots to be had in the rivet hole of taper counter sink, rivet slightly exceeds cutter hub, the raised area riveting is flat, make rivet two all have the taper countersunk head and with the rivet hole tight fit, be about in the uniform snaps breach of the firm power that the is embedded in body periphery in cutter head bottom.When changing cutter head, elder generation stamps out rivet hole with sunk head rivet or bores, and extracts old cutter head out again in the snaps breach, inlays one group of new cutter head according to the method described above and gets final product.

The utility model adopts at snaps breach and cutter head both sides and all is provided with many emboss pits that coincide mutually, makes cutter head not produce transverse shift and loosening in the snaps breach, and two, the flat back of sunk head rivet riveting is reverse taper, non-ly can not deviate from rivet hole through punching press.Firm the locking in cutter head bottom is positioned in the snaps breach, and method for embedding is simple, and the cutter user only need buy cutter head back and can change voluntarily, reduces downtime and saves the round transport expense; Weld heating on cutter hub not can prolong service life of cutter hub; Metal and nonmetallic materials can be made cutter head and be embedded in the cutter hub periphery, facility selects for use material and the process that price is lower, cutting efficiency is higher to make cutter head at the stone material of different quality, further improve work efficiency, reduce cutter manufacturing cost and use cost.

The utility model is described in further detail below in conjunction with accompanying drawing.

A kind of combined type stone material cutter, it mainly is made up of the cutter hub 2 that has centre bore 1 and one group of cutter head 3, cutter hub 2 peripheral uniform snaps breach 5, the both sides of snaps breach 5 all are provided with many emboss pits 7, one side is provided with the semi-round groove 6 that all there is tapering at two ends, cutter head 3 is combined by mosaic block 8 and cutting cube 10, the both sides, bottom of mosaic block 8 all are provided with the emboss pit 11 that matches with snaps breach 5 both sides, one side is provided with the semi-round groove 9 that all there is tapering at two ends, top is provided with the mounting groove 13 of affixed cutting cube 10, during affixed metal species cutting cube, cutting cube 10 is welded in the mounting groove 13, during affixed nonmetal grinding segment class cutting cube, cutting cube 10 edge folders are bonded in the mounting groove 13, make cutting cube 10 and mosaic block 8 firm be combined into cutter head 3.When the periphery of cutter hub 2 is inlayed cutter head 3, the recess of the high spot of both sides, cutter head 3 bottom emboss pit 11 being aimed at snaps breach 5 both sides emboss pits 7 inserts snaps breach 5, sunk head rivet 4 is pierced into the rivet hole 12 that the taper counter sink is arranged by two semi-round grooves 6 and 9 two ends of forming, rivet 4 exceeds cutter hub 2, the raised area riveting is flat, make its two all have the taper countersunk head and with rivet hole 12 tight fits, be about to the firm snaps breach 5 that is embedded in cutter hub 2 in bottom of cutter head 3, the rivet 4 of two taper countersunk head is non-can not deviate from rivet hole 12 through punching press, cutter head 3 just can not deviate from snaps breach 5 yet, uses as safe as a house reliable.When changing cutter head 3, elder generation stamps out rivet hole 12 with sunk head rivet 4 or bores, and extracts cutter heads 3 out from snaps breach 5 again, can inlay one group of new cutter head 3 at the periphery of cutter hub 2 according to above-mentioned method for embedding, changes the simple easy operating of method of cutter head.
