Abstract
The invention relates to an ultrafine grain hard alloy bimetallic strip saw blade, which comprises a saw blade body, wherein a plurality of tooth tip bodies are equidistantly arranged on the upper part of the saw blade body; tooth tip slots are formed on the middle parts of the tooth tip bodies; hard alloy tooth tips are welded in the tooth tip slots; two adjacent hard alloy tooth tips are respectively arranged on the two sides of the upper part of the saw blade body; one of the adjacent hard alloy tooth tips is welded at one end of a corresponding tooth tip slot while the other one is welded at the other end of the corresponding tooth tip slot; and the outer side walls of the hard alloy tooth tips are protruded out of the outer side wall of the saw blade body. The ultrafine grain hard alloy bimetallic strip saw blade has the advantages that the saw blade is economical and practical, the production efficiency is greatly promoted, the costs of mechanical processing, labor and electric energy are reduced, the hard alloy tooth tips are firm and are difficult to crack and fall, and the service life is long.
Description
Technical field
The present invention relates to a kind of ultrafine dust carbide alloy bi-metal bandsaw blades.
Background technology
At present; prior art is applied to the saw blade of metal, nonmetallic materials sawing processing; generally use various ways such as strip, band shape, plate-like; yet the sort of form no matter; they all belong to the same one that sawtooth combines with body; this version; though certain advantage is arranged, process simple, convenience as making, yet often can not satisfy the demand of sawing difficult-to-machine material; the saw of this integral structure; make hackle distortion, rust, chip removal difficulty through regular meeting, sawing is crooked, and processing effect is poor; efficient is low, and service life is short.
Bi-metal bandsaw blades is because of it has efficiently, the characteristics of low energy, energy-conservation, material-saving are by industry extensive uses such as machine-building, metallurgy, chemical industry, military projects.It is to be welded through vacuum electronic by cutting edge high-speed steel sawtooth and superstrength alloy steel matrix, through the compound cutting tools of a series of hot and cold processing technologys manufacturings; Existing bi-metal bandsaw blades, its tooth portion cutting power, wearability are better, this mainly is because the selection of existing heat treatment process parameter is determined at tooth portion high speed steel material, and saw blade matrix alloy steel is under this technological specification is handled, its fatigue performance greatly reduces, under the situation that the wearing and tearing of tooth portion are minimum in so just causing using, performance is intact, crackle even phenomenon of rupture, generation tooth portion and matrix nonsynchronous problem that lost efficacy appears in matrix, influence the service life of bi-metal bandsaw blades, the waste raw material.
Summary of the invention
The purpose of this invention is to provide a kind of ultrafine dust carbide alloy bi-metal bandsaw blades, to overcome the prior art above shortcomings.
The objective of the invention is to be achieved through the following technical solutions:
A kind of ultrafine dust carbide alloy bi-metal bandsaw blades, comprise the saw blade body, described saw blade body top equidistantly is provided with some crown bodies, described crown body middle part is provided with the crown groove, be welded with carbide alloy crown and two adjacent carbide alloy crowns in the described crown groove and be located at the both sides on saw blade body top respectively, one of them carbide alloy crown is welded on an end of corresponding crown groove, another carbide alloy crown is welded on the other end of corresponding crown groove, and the lateral surface of carbide alloy crown protrudes the lateral surface of saw blade body.
Beneficial effect of the present invention is: economical and practical, improved production efficiency greatly, and reduced machined, artificial, the cost of electric energy; Crown is welded with the ultra micron carbide alloy, can reach the purpose with soft anticracking; Crown is harder, and durable in use, crown firmly is difficult for carnassial tooth, falls tooth, long service life; Need not break-in during use, can improve the service life of the cutting efficiency and the sawtooth of bi-metal bandsaw blades, enterprise is reduced cost.

The specific embodiment
Shown in Fig. 1-7, the described ultrafine dust carbide alloy of embodiment of the invention bi-metal bandsaw blades, comprise saw blade body 1, described saw blade body 1 top equidistantly is provided with some crown bodies 3, described crown body 3 middle parts are provided with crown groove 4, be welded with carbide alloy crown 2 and two adjacent carbide alloy crowns 2 in the described crown groove 4 and be located at the both sides on saw blade body 1 top respectively, one of them carbide alloy crown 2 is welded on an end of corresponding crown groove 4, another carbide alloy crown 2 is welded on the other end of corresponding crown groove 4, and the lateral surface of carbide alloy crown 2 protrudes the lateral surface of saw blade body 1.
The manufacture method of the saw blade sawtooth of the tungsten carbide button of the big footpath of sawing material (diameter 600-1500mm), the Hang temper fire of former Jin of saw blade tempering 2 times, make its hardness and toughness reach optimum state, adopt winding to connect the die-cut sawtooth of punching method automatically again, the method is than existing milling, the method of line cutting or laser cutting wants fast 50-100 doubly, and per minute can be made 180 teeth, and is economical and practical.Improved production efficiency greatly, reduced machined, manually reached the cost of electric energy, through fibre weldering mode, the ultra micron carbide alloy fibre that adopts hardness to reach 92 ° is soldered on the die-cut good crown, reaches and is with soft anticracking, the long-lived effect of denticle again.Adopt unique mosaic mode: towards recessed 60 percent place tungsten carbide button crown, leave 40 percent mother metal protection carbide alloy crown at belt body crown position, make crown more firmly be difficult for carnassial tooth, fall tooth.It is above to adopt the method that doubled the service life of band saw.Carry out the four sides reconditioning of pipeline system monodentate again, its precision reaches 0.002mm, need not break-in during use, just can improve the service life of the cutting efficiency and the sawtooth of bi-metal bandsaw blades, and enterprise is reduced cost.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but on its shape or structure, do any variation; every have identical with a application or akin technical scheme, all drops within protection scope of the present invention.
