Abstract
A low-noise environment-friendly hard alloy tooth circular saw blade belongs to the technical field of tools for processing steel products and is used for reducing the noise of saw cutting. The technical scheme is as follows: the saw blade consists of a disk-shaped saw blade body, the periphery of which is provided with tooth holders and hard alloy tool bits fixed on all the tooth holders; and the saw blade body comprises two layers and a damping layer is arranged between the two layers of the saw blade body. The blade body adopts a multilayer structure with the damping layer added in the middle. During the process of sawing a seamless tube, a welded tube or a steel rail, the damping layer can effectively reduce the intensity of cutting noise and lessen noise pollution, thus effectively improving the quality of production environment.
Description
Technical field
The utility model relates to a kind of improved hard-metal insert saw blade, belongs to the technical field of tools of working steel products.
Background technology
Iron and steel enterprise generally all will use the hard-metal insert saw blade that product is carried out scale sawing (comprising that removal end to end) when producing seamless steel pipe, welded tube and rail.The hard-metal insert saw blade is directly to weld carbide bit on the tool steel lamellar body, make after the accurate sharpening profile of tooth angle of process again, in use, impact, rub because the sawtooth of hard-metal insert saw blade and workpiece produce, can produce bigger cutting noise (reaching as high as more than 95 decibels), bring noise pollution to the production scene, the health of field worker in serious threat.For addressing the above problem, difform narrow slit cuts in the producer that has on the saw blade lamellar body, though this measure can reduce the cutting noise to a certain extent, noise reduction is still undesirable, is difficult to satisfy the requirement of production scene.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can satisfy the low noise environment-friendly type hard-metal insert saw blade that the production scene requires.
Problem described in the utility model realizes with following technical scheme:
A kind of low noise environment-friendly type hard-metal insert saw blade, the discoid saw blade lamellar body that is had toothholder by periphery constitutes with the carbide bit that is fixed on each toothholder, and described saw blade lamellar body is divided into two-layer, is provided with damping layer between the two-layer saw blade lamellar body.
Be connected by rivet or soldering point between the above-mentioned low noise environment-friendly type hard-metal insert saw blade, described damping layer and two-layer saw blade lamellar body, described rivet or soldering point evenly distribute on the saw blade lamellar body.
Above-mentioned low noise environment-friendly type hard-metal insert saw blade, described damping layer can be the metal material different with two lamellasomes, process hot rolling or cold rolling method are inserted between the lamellar body and are formed firm combination.
Above-mentioned low noise environment-friendly type hard-metal insert saw blade has centre bore in the middle of the described saw blade lamellar body, be provided with driving hole around the described centre bore, is provided with fabrication hole in addition in border, driving hole place.
Above-mentioned low noise environment-friendly type hard-metal insert saw blade, described driving hole evenly distributes around centre bore.
Above-mentioned low noise environment-friendly type hard-metal insert saw blade, described fabrication hole evenly distributes around centre bore.
Saw blade lamellar body of the present utility model adopts the sandwich construction structure, between the alloy tool steel lamellar body, add damping layer, in the process of sawing seamless steel pipe, welded tube or rail, damping layer can reduce to cut the intensity of noise effectively, reduce noise pollution, thereby effectively improved the quality of production environment.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view;
Fig. 3 is the structural representation of sawtooth.
Each label is among the figure: 1, saw blade lamellar body; 2, toothholder; 3, rivet; 4, damping layer; 5, centre bore; 6, driving hole; 7, fabrication hole; 8, alloy cutter head.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, saw blade lamellar body 1 of the present utility model adopts sandwich construction, between the alloy tool steel lamellar body, add a damping layer 4, the thickness of damping layer 4 is 0.10-0.50mm, in sawing process, can reduce to cut the intensity of noise effectively, thereby improve the environmental quality of production scene.The material of saw blade lamellar body 1 adopts high duty alloy tool steel such as 8CrV, 75Cr1, damping layer 4 adopts copper, mild steel, aluminium or macromolecular material, adopt riveted joint or welding or rolling compound mode to connect between saw blade lamellar body 1 and the damping layer 4, rivet 3 adopts carbon steel to make, alloy cutter head 8 adopts P25-P40 series ultrafine gain size material, its hardness height, good toughness, wearability are good, can adapt to the cutting state with certain shock loading.
Several transmission circular holes 6 evenly distribute beyond the centre bore 5, the aperture of saw blade lamellar body 1 waist is fabrication hole 7 (hole for hoist), on the toothholder 2 of saw blade lamellar body 1 by the method for soldering several carbide cutter tool pieces 8 of burn-oning, weld seam has very high shearing strength, alloy knife piece 8 sharpenings go out fundamentals such as suitable anterior angle, relief angle, side chamfering, chip-breaker, to adapt to the sawing requirement of different workpieces.
Product specification of the present utility model is
Both can sawing
Solid blank, also can sawing
The heavy rail of seamless steel pipe, welded still pipe, corresponding size and H shaped steel etc.
The utility model can be installed on the various sawing devices and use, after saw blade is installed on and also fixes by driving hole 6 on the mechanical main shaft, can adjust rotary speed, feed speed, cut off by advance and retreat or level advance and retreat action up and down and to be clamped in various steel pipes, pipe, heavy rail and the shaped steel of stablizing in the clamping device, can singly prop up also in a row sawing, the sawing mode of saw blade can be downward feeding, horizontal feed and to tiltedly direction feeding down.
