Description
Technical field
The present invention relates to steel and wood cutting equipment technical field, especially a kind of saw blades of cutting-grinding dual-purpose.
Background technology
Saw blade is widely used in the industries such as metallurgy, machinery, processing of stone, to aluminium alloy, plastic-steel, color steel, solid wood, plane
When the materials such as card, density board are cut, due to the problems such as there are section tool marks, chipping or burrs after cutting, cause to cut
Face docking registration is low, needs cut surface of polishing after cutting, and thus needs to cut off equipment and flour milling equipment loads onto saw respectively
Piece and grinding wheel（The angular preceding sanding machine of general flour milling）, or the angular preceding sanding machine of cut-out flour milling, on angular preceding sanding machine
Replacement tool, is worked alternatively, the working time for increasing operating personnel invisible in this way, reduces working efficiency, and grind
The verticality of the flatness in face, flour milling and proximate matter is also bad.
Invention content
Technical problem to be solved by the invention is to provide a kind of saw blades of cutting-grinding dual-purpose, can be completed at the same time cutting and beat
Abrasive cut-off face, greatly improves the efficiency, and improves the flatness of flour milling, the verticality of flour milling and proximate matter, and cutter head is inserted to be set
It counts while also improving impact of the saw blade by cutting material to saw blade cutter tooth in cutting process, cutter head is not easy to fall.
To achieve the above object, technical scheme of the present invention includes：Blade body, the double-deck cutter head, the back of tooth and grinding wheel, in institute
It states in blade body, the same side for being fitted in each back of tooth is both provided with groove, and the double-deck cutter head is welded in groove；
The grinding wheel includes upper grinding wheel and lower grinding wheel, and the upper grinding wheel and lower grinding wheel are annular shape, the upper grinding wheel and
The lower grinding wheel is separately positioned on the both sides of blade body, is both provided on the blade body, upper grinding wheel and lower grinding wheel mutually
The bolt hole of adaptation, the upper grinding wheel and the lower grinding wheel are bolted in blade body.
Preferably, the bilayer cutter head includes interior cutter head and outer cutter head, and the interior cutter head and the fitting of outer cutter head, interior cutter head
It is bonded with the back of tooth.
Preferably, the interior cutter head is suppressed by powdered hard alloy reworked material.
Preferably, the outer cutter head is suppressed by the powdered primary material of hard alloy.
Preferably, the 65%-80% of the width of back of tooth maximum distance between the two neighboring back of tooth.
Preferably, the grinding wheel is resin anchoring agent diamond grinding wheel.
Preferably, the quantity of the bolt hole is three, angle is 120 ° between each bolt hole.
Preferably, the hardness of the primary material of powdered hard alloy is HRA91 or more and its cutter head trade mark is YG6 with top grade
Matter.
Preferably, the upper grinding wheel and lower grinding wheel are frustum cone structure, the angle of frustum cone structure bottom surface and side is 60 °.
Preferably, the hard alloy is tungsten-cobalt alloy.
Good effect of the present invention is as follows：
1. upper grinding wheel and lower grinding wheel are fixed in blade body by countersunk head screw, resin bonding agent diamond is selected
Grinding wheel, resin anchoring agent diamond grinding wheel are more smooth to the reparation of cut surface, and can be preferably bonded with blade body, spiral shell
Bolt throughhole is three, between angle be 120 °, such design makes saw blade during the work time, can keep stable, as a result,
Invention can be completed at the same time cutting and polishing face, substantially increase cut surface and verticality and flatness by cutting material,
Improve working efficiency.
2. in blade body, the side setting for being fitted in each back of tooth is fluted, and each groove is in its fitting
The back of tooth the same side, the double-deck cutter head is fixed by welding in groove, and the double-deck cutter head is embedded in groove as a result, using this
The embedded welding for inventing this creativeness substantially increases saw blade and is rushed to saw blade cutter tooth by cutting material in cutting process
Hitting property, cutter head are not easy to fall.
3. the back of tooth uses the wide back of tooth design i.e. 65%-80% of width maximum distance between the two neighboring back of tooth of the back of tooth,
The requirement of saw blade impact resistance in entire cutting process is substantially increased, even if having powerful resistance situation by cutting object
Under, the back of tooth is also not easy to deform or is broken, and substantially increases the stability of saw blade.
4. cutter head is the double-deck cutter head, it is divided into interior cutter head and outer cutter head, the interior cutter head and the fitting of outer cutter head, interior cutter head and tooth
Back of the body fitting.Interior cutter head is suppressed by tungsten-cobalt alloy reworked material, and the cost of tungsten-cobalt alloy reworked material is relatively low, impurity is more, hardness
Low, good toughness, weld strength are high, it is possible thereby in the double-deck cutter head when being welded on saw blade, avoid to draw in welding process and answer
Destruction of the power to cutter head, avoids the generation of cold crack, improves cutter head intensity；Outer cutter head by the compacting of tungsten-cobalt alloy primary material and
At the characteristic that the primary material hardness of tungsten-cobalt alloy is high, wearability is good, intensity is high, spy's setting is participating in cut portion, as a result,
Make the double-deck cutter head in use, can be good at cutting article, be not easy to consume.
Grinding wheel and lower grinding wheel are frustum cone structure on 5., and the angle of frustum cone structure bottom surface and side is 60 °, and this design makes
Grinding wheel is obtained to proceed directly to, by the gap of cutting material, be convenient for reconditioning cut surface when cutting material.
