Abstract
The utility model relates to a toothed diamond saw blade for cutting non-metal materials, which comprises a base body and a cutter tooth; the base body, diamond powder and metal powder are pressed and sintered into integration; the cutter tooth and the base body are divided into uniform cutter blades by a plurality of tooth slots. The utility model is characterized in that the toothed diamond saw blade also comprises metal nets which are respectively arranged at an upper and a lower parts of the saw blade; the metal net and the base body are combined into integration, which is combined with the cutter tooth. The utility model enhances combined degrees of the saw blade base body and the cutter tooth, and simultaneously enhances the bending-resistant strength of the base body.
Description
The present invention relates to a kind of cutting tool, relating in particular to a kind of is the saw blade of material with the diamond.
The band tooth diamond saw blade of prior art as shown in Figure 1, comprise matrix and cutter tooth, it is by diamond dust metal dust and matrix are put into punching block compression moulding, and then puts into sintering furnace and carry out liquid-phase sintering, polishes after cooling again, sprays paint, puts the first edge on a knife or a pair of scissors; Or, put into the compression moulding of hot press pressurized, heated again by diamond dust metal dust and matrix are put into punching block, polish again after cooling, spray paint, put the first edge on a knife or a pair of scissors.The matrix of this kind saw blade combines the strength of just leaning on cutter tooth and matrix to inlay with cutter tooth portion, adhesion is little, in use normal coping saw blade rotating speed is too high, or cool off bad, be cut the drag effect of material or the user exerts oneself excessive or in cutting process the improper side force of having used, or the defective of coping saw blade itself, usually cause cutter tooth cracked, or cutter tooth comes off from matrix, and cutter tooth or fragment fly out at a high speed, very easily cause industrial accident; And this kind saw blade is easy deformation in use, has influenced the service life of saw blade.
Defective at prior art, the purpose of this utility model is to provide a kind of band tooth diamond saw blade, it is provided with wire netting respectively by the both sides up and down at saw blade, make itself and matrix bond together, carry out compacting sintering with the diamond dust metal dust again, thereby when making woven wire and matrix strong bonded, the cutter tooth of woven wire and saw blade also combines, thereby has strengthened the combination degree of matrix and cutter tooth and strengthened the bending strength of matrix.
The purpose of this utility model is achieved in that
A kind of band tooth diamond saw blade comprises
Matrix;
Cutter tooth is by forming described matrix and diamond dust metal dust compacting sintering;
Several teeth groove are divided into uniform gear piece with cutter tooth and matrix; It is characterized in that
It also comprises wire netting, is arranged at the both sides up and down of described saw blade respectively, and described wire netting and matrix bond and combine with described cutter tooth together.
Described wire netting and cutter tooth be combined into fusion.
Described diamond saw blade is by putting into punching block compression moulding with wire netting, diamond dust metal dust and matrix, puts into sintering furnace then and carries out liquid-phase sintering and form.
Described diamond saw blade is by putting into punching block with wire netting, diamond dust metal powder art and matrix, and the pressurized, heated compacting forms in hot press.
The twine material of described wire netting is iron, steel, copper, nickel, aluminium, lead, zinc, tin, tungsten or molybdenum.
The twine material of described wire netting is the metal of two or more metal of chosen from Fe, steel, copper, nickel, aluminium, lead, zinc, tin, tungsten, molybdenum by plating or other painting method be combined into.
The twine material of described wire netting is the alloy of chosen from Fe, steel, copper, nickel, aluminium, lead, zinc, tin, tungsten or molybdenum.
Diamond saw blade of the present utility model is provided with wire netting by the both sides up and down at saw blade, before compacting or in the pressing process matrix is combined with wire netting, again together with net+matrix and diamond dust metal dust compacting sintering, make the inlaying the power that combine of saw bit matrix and cutter tooth except cutter tooth and matrix, wire netting and matrix strong bonded, the twine and the cutter tooth of wire netting fuse together simultaneously, strengthened the combination degree of matrix and cutter tooth greatly, in use cutter tooth can be not cracked, yet can not come off, fly out from matrix; Simultaneously; owing to combine wire netting; the bending strength of matrix also strengthens greatly, and through the experiment of lift heavy thing, the bending strength of traditional diamond saw blade substrate cutter tooth joint portion is 2.00～3.00 kilograms; after the improvement of the utility model screening; its bending strength can reach 5.00～6.00 kilograms, and is in use not yielding, prolonged the service life of saw blade; also can reduce the dry sound that produces in the use, play the effect of protection environment.
Below, in conjunction with the accompanying drawings,, describe the utility model in detail by description to the utility model preferred embodiment.
Fig. 1 is the saw blade partial schematic diagram of prior art;
Fig. 2 is a saw blade partial schematic diagram of the present utility model;
Fig. 3 is a saw blade front view of the present utility model.
Fig. 2 and Fig. 3 are the schematic diagram of a preferred embodiment of the present utility model, the utility model comprises matrix 1, cutter tooth 2 and wire netting 3, matrix 1 is the flat pattern round steel sheet of a band endoporus, its diameter can be all size (D75mm～D500mm) as required, wire netting 3 is covered in the upper and lower surface of matrix, and cutter tooth 2 is positioned at the outer rim of matrix 1, and overlaps with the extension of wire netting 3; Several teeth groove 4 are divided into uniform gear piece with cutter tooth 2 and matrix 1.Manufacturing process of the present utility model is as follows:
Diamond dust metal dust and matrix are put into punching block compression moulding, put wire netting respectively in the both sides up and down of matrix before the compacting, wire netting can be wire netting, steel wire, copper mesh, nickel wire net, aluminium wire netting, lead wire net, zinc silk screen, tin silk screen, tungsten silk screen or molybdenum filament net; And aforementioned two or more metals are by electroplating or the wire netting of other painting method be combined into etc., or the wire netting of above metal alloy.Matrix and wire netting combine in pressing process, carry out liquid-phase sintering putting into sintering furnace then, and wire netting and cutter tooth fuse together, and polish, spray paint, put the first edge on a knife or a pair of scissors, are packaged into product after the cooling; Or wire netting, diamond dust metal dust and matrix put into punching block, and put into the compacting of hot press pressurized, heated again and form, polish, spray paint, put the first edge on a knife or a pair of scissors, be packaged into product after cooling again.The utility model can be used for nonmetallic cuttings such as marble, granite, ceramic tile, cement products, concrete, refractory material.
Should be understood that the one of ordinary skilled in the art can make various suitable changes or distortion under the prerequisite that does not break away from the utility model spirit essence, but these changes or distortion all should belong to scope of the present utility model.
