Abstract

The invention relates to a circular saw, a band saw and a gang saw for rolling and stamping corrugated teeth, and belongs to a cutting tool. The circular saw, the band saw and the gang saw for rolling and stamping the corrugated teeth are characterized by mainly comprising a non-cutting body and a cutting body which are integrally rolled or stamped, wherein a corrugated cutting body is directly rolled or stamped on the circumferential part or the upper part with section steel of a disc steel plate; the adjacent bevel edges of the corrugated cutting body are intersected at an included angle of 30 to 120 degrees, and intersections are uniformly distributed on the non-cutting body in a staggered mode back and forth; or a super-hard material is pressed and embedded in the front and rear surfaces of the cutting body to form a super-hard material layer while the cutting body is formed, and a wear-resistant layer made of a tungsten cobalt alloy, ceramic or plastic is sprayed on the super-hard material layer; or a super-hard material layer made of diamond or cubic boron nitride (CBN) is electroplated or soldered on the front and rear corrugated surfaces of the cutting body. The circular saw, the band saw and the gang saw have low cost, a high cutting speed and long service life, and are suitable for cutting metallic and nonmetallic materials.

Description

Rolling, as to strike out corrugated teeth circular saw, band saw and gang saw

Technical field

The invention belongs to cutting tool, especially relate to a kind of circular saw, band saw and gang saw.

Background technology

The cutting tool that now is used for cutting metal and nonmetallic materials is generally circular saw (minute cylindrical and inner circle), band saw, gang saw and silk saw (being scroll saw), divide again resin cutting slice and the tooth punching take the 65Mn steel matrix as the master, weldering tooth and the multi-block type saw blade made with aluminium oxide and carborundum in the circular saw, cutting metal material is mainly take aluminium oxide, carborundum resin cutting slice as main, but easy contaminated environment in its cutting process, dangerous, and be the high energy consumption product; And take circular saw, band saw and gang saw, the silk saw that the 65Mn material is made as main steel plate following several form is arranged usually: 1), in the periphery of disk steel plate or with a side milling tooth of steel or rush tooth and be pointed shape, then with tooth section heat-treatment quenching, the general cutting metal and nonmetal that is used for, behind the odontotripsis again fit quench and reuse; 2), in the periphery of disk steel plate and with a side of steel, be welded carbide bit or diamond block are used for cutting metal and nonmetal; 3), electroplate ultra hard material layer in the periphery of ring steel plate or interior week and with a side of steel, be used for cutting metal and nonmetal; 4), free abrasive in addition at the disk steel plate and in the rapid movement of steel, steel wire, carry out the cutting non-metal material, such as the cutting silicon crystal; But above all, all time-consuming during making, cost is higher, and cutting efficiency is lower.

Summary of the invention

The purpose of this invention is to provide a kind of rolling, circular saw, band saw and gang saw of striking out corrugated teeth, can cutting metal and nonmetallic materials, not only make simple, cost is low, and larger and continuous chip removal space and cutting body are at a high speed arranged, and cutting speed is fast, consumed power is little, long service life.

The object of the present invention is achieved like this: a kind of rolling, strike out the circular saw of corrugated teeth, band saw and gang saw, comprise steel matrix, this steel matrix is disc or band shape, this steel matrix can adopt 65Mn steel or other steel, it is characterized in that: this is rolling, strike out the circular saw of corrugated teeth, band saw and gang saw mainly are comprised of the rolling or non-cutting body of punching press all-in-one-piece and cutting body, be the circumferential part of disk steel plate or with the top Direct Rolling of shape steel or stamp out corrugated cutting body in steel matrix, steel matrix part not rolling or punching press is non-cutting body, the adjacent hypotenuse of each of this corrugated cutting body be that 30 ° of-120 ° of angles intersect and each cross-shaped portion to be front-back staggered at non-cutting body uniform, the angle of the crossing hypotenuse of each of this corrugated cutting body is take 60 °-90 ° as best, and the angle of the crossing hypotenuse of each of this corrugated cutting body can be the circular arc angle, space between the hypotenuse that each two twenty percent angle intersects is chip area, the space of this chip area is large, be difficult for stopping up, the intersection that the adjacent hypotenuse of this cutting body is positioned at front side and rear side all is to be from non-cutting body to cutting body top laterally, when the immediately conventional quenching heat treatment after rolling or punch forming of this cutting body, this is rolling, the circular saw that strikes out corrugated teeth is mainly used in cutting off at a high speed various steel, substitutes the aluminium oxide resin cutting slice and the toothless saw (be actually at the disk steel plate and be milled with tooth) that use at present; Or when hot rolling, drop stamping cutting body, utilize the thermoplastic state of cutting body directly to add superhard material, namely when being shaped, cutting body forms ultra hard material layer in the corrugated front and rear surfaces with superhard material pressure embedding cutting body, this ultra hard material layer can be diamond or CBN, to increase the abrasion resistance of cutting body, and on this ultra hard material layer spraying abrasion-proof layer again, this wearing layer can be tungsten Cobalt alloy, pottery or plastics; Or by plating and the method for brazing of routine, electroplate or soldering one deck ultra hard material layer in the corrugated front and rear surfaces of cutting body, this ultra hard material layer can be diamond or CBN, is used for cutting metal and nonmetal.

This is rolling, strike out the circular saw of corrugated teeth, band saw and gang saw are to pass through local heat, make the circumferential part of disc steel matrix or reach rolling temperature with the top of shape steel matrix, send to hot rolling limit, special roller limit, roll out continuous corrugated cutting body, or after the circumferential part of disc steel matrix or the top local heat with the shape steel matrix, directly stamp out continuous corrugated cutting body, or at the circumferential part of disc steel matrix or cold rolling with the top of shape steel matrix, cold punching extrudes continuous corrugated cutting body, then as required the quick conventional quenching of corrugated cutting body is processed, this is rolling, strike out the circular saw of corrugated teeth, band saw and gang saw, make simple, cost is low, and cutting speed is fast, is applicable to the cutting of Metal Cutting and nonmetallic materials, especially be applicable to the high-speed cutting of steel, long service life, simultaneously, the chip removal space is large and continuous, be difficult for stopping up, cutting resistance is little, and power consumption is also little, also can replace cutting the silk saw of silicon crystal simultaneously.

Rolling, the circular saw, band saw and the gang saw that strike out corrugated teeth proposed by the invention, rational in infrastructure, safe and reliable, not only make simple, cost is low, and cutting speed is fast, long service life, be applicable to the cutting of Metal Cutting and nonmetallic materials, especially be applicable to the cutting of steel, stone material and silicon crystal.

Now in conjunction with the accompanying drawings and embodiments circular saw, band saw and gang saw rolling, that strike out corrugated teeth proposed by the invention are further described.
