Abstract

The utility model provides an ultra -thin type carbide saw blade, it relates to cutter technical field, and the sawtooth that it contains cemented carbide substrate, cockscomb structure bears lug, basin, sawtooth, iron -based inserted block, cemented carbide substrate's the periphery sawtooth that is provided with a plurality of cockscomb structures bear the lug, and the sawtooth of cemented carbide substrate and cockscomb structure bears lug formula structure as an organic whole, the sawtooth of every cockscomb structure bears and is provided with the basin between the lug, fixedly connected with iron -based inserted block on the non - cutting edge of sawtooth, the sawtooth of iron -based inserted block and cockscomb structure bears lug plug -in mounting to be connected, cemented carbide substrate's thickness be the 1.2 -1.5 millimeter. The utility model discloses the sawtooth width can and be decided according to the joint -cutting requirement, the activity that more makes its presence or power felt when especially saw cutting the zigzag or the officious announcement width line of rabbet joint, and can significantly reduce sawtooth and the heat of cemented carbide substrate friction production and the heat that conducts to the base member when saw cutting avoid the base member appeared by heat altered, the premature failure.

Description

A kind of ultrathin sintered carbide circular saw

Technical field

The utility model relates to cutting-tool engineering field, is specifically related to a kind of ultrathin sintered carbide circular saw.

Background technology

Hard alloy saw blade is that woodwork processes the most frequently used cutlery, and the quality of hard alloy saw blade and the quality of converted products have substantial connection.Correct hard alloy saw blade of reasonably selecting has great importance for process-cycle of improving the quality of products, shorten, minimizing processing cost.Hard alloy saw blade comprises the kind of alloy cutter head, multiple parameter such as material, diameter, the number of teeth, thickness, profile of tooth, angle, aperture of matrix, and these parameters decide working ability and the cutting ability of saw blade.Select to need correctly to select saw blade according to the direction of the speed of the kind of sawing material, thickness, sawing, sawing, feeding speed, saw kerf width during saw blade.

The kind that carbide alloy is conventional has W-Co kind (code name YG), tungsten titanium class (code name YT).Because the carbide alloy impact resistance of W-Co kind is better, use more extensive in wood working industry.In timber processing, conventional model is the percentage of YG8-YG15, YG numeral cobalt content below, and cobalt content increases, and toughness and the bending strength of alloy increase, but hardness and wearability decline to some extent, will be selected according to actual conditions.

In sawing process, saw blade runs up, and saw bit matrix and talus glacier produce fretting wear.Due to the gauge wear of sawtooth and side wear inconsistent, when sawtooth working lining will run out of, the friction of saw bit matrix and landwaste strengthens, cause " binding ", this will cause wearing and tearing and the distortion of saw bit matrix, the heat that during sawing, sawtooth and matrix friction can produce and to matrix heat conduction, the easy temperature distortion of matrix, premature failure.

Utility model content

The purpose of this utility model is defect for prior art and deficiency, provides the ultrathin sintered carbide circular saw that a kind of structure is simple, reasonable in design, easy to use.

For achieving the above object, the technical solution adopted in the utility model is: it comprises hard alloy substrate, the carrying of jagged sawtooth lug, tank, sawtooth, iron-based inserted block; The periphery of described hard alloy substrate is provided with some jagged sawtooth carrying lugs, and hard alloy substrate and jagged sawtooth carrying lug are integral type structure, tank is provided with between each jagged sawtooth carrying lug, the non-cutting edge of sawtooth is fixedly connected with iron-based inserted block, iron-based inserted block and jagged sawtooth carry lug plug-in mounting and are connected; The thickness of described hard alloy substrate is 1.2-1.5 millimeter.

As preferably, described sawtooth and iron-based inserted block adopt socket welding type to be connected, and iron-based inserted block and jagged sawtooth carry lug and also adopt socket welding type to be connected.

After adopting said structure, the beneficial effect that the utility model produces is: the ultrathin sintered carbide circular saw of one described in the utility model, tooth width can require according to joint-cutting and determine, especially more make its presence or power felt when sawing zigzag or the non-uniform width line of rabbet joint activity, sawtooth and the fricative heat of hard alloy substrate and the heat that conducts to matrix when can greatly reduce sawing, avoid matrix temperature distortion, premature failure, the utility model have structure simple, arrange rationally, the advantage such as cost of manufacture is low.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to such as Fig. 1---shown in Fig. 2, this detailed description of the invention adopts following technical scheme: it comprises hard alloy substrate 1, the carrying of jagged sawtooth lug 2, tank 3, sawtooth 4, iron-based inserted block 5; The periphery of described hard alloy substrate 1 is provided with some jagged sawtooth carrying lugs 2, and hard alloy substrate 1 and jagged sawtooth carrying lug 2 are integral type structure, tank 3 is provided with between each jagged sawtooth carrying lug 2, the non-cutting edge of sawtooth 4 is fixedly connected with iron-based inserted block 5, iron-based inserted block 5 and jagged sawtooth carry lug 2 plug-in mounting and are connected; The thickness of described hard alloy substrate 1 is 1.2-1.5 millimeter.

As preferably, described sawtooth 4 adopts socket welding type to be connected with iron-based inserted block 5, and iron-based inserted block 5 and jagged sawtooth carry lug 2 and also adopt socket welding type to be connected.

After adopting said structure, the beneficial effect that this detailed description of the invention produces is one described in this detailed description of the invention ultrathin sintered carbide circular saw, tooth width can require according to joint-cutting and determine, especially more make its presence or power felt when sawing zigzag or the non-uniform width line of rabbet joint activity, sawtooth and the fricative heat of hard alloy substrate and the heat that conducts to matrix when can greatly reduce sawing, avoid matrix temperature distortion, premature failure, this detailed description of the invention have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
