Description

A kind of saw blade

Technical field

The utility model relates to the cutting-tool engineering field of sawing machine or saw cutting device, and more particularly, it relates to a kind of saw blade.

Background technology

Saw blade is a kind of cutting tool, is widely used in concrete, refractory material, stone material, the processing of the hard brittle materials such as pottery. Diamond saw blade is mainly made up of two parts; Matrix and cutter head. Matrix is the main support part of bonding cutter head, cutter head is the part that in use plays cutting, cutter head can in use and constantly consume, matrix can not, why cutter head can play cutting is because wherein contain diamond, diamond is as the hardest current material, the processed object of its friction cuttings in cutter head. Diamond particles is wrapped in cutter head inside by metal.

At present, application number is that 201420488046.8 Chinese patent discloses a kind of saw blade for paddle-tumble, comprise saw bit matrix, be arranged on the sawtooth on saw bit matrix circumference and be arranged on the installing hole on saw bit matrix, chip pocket at the bottom of tooth is set on the described saw bit matrix between adjacent sawtooth, saw-tooth tool bit is installed in meeting on the saw bit matrix toothholder of the direction of cutting of described sawtooth, meet to cutting direction in the cutting face of described saw blade tip, described saw blade tip is trapezoid structure, and the cutting edge top edge of described saw blade tip is provided with the V-shaped groove with concave arc on bottom. because the V-shaped groove on this saw blade tip is the top that is positioned at cutter head, the cutting face of saw blade tip is still a plane, and in the time of cutting, the resistance being subject to is still larger comparatively speaking.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of and is applicable to cut timber, durable, the life-span long, the saw blade of good heat dissipation.

For achieving the above object, the utility model provides following technical scheme:

A kind of saw blade, comprise blade body, be located at the sawtooth on blade body circumference, tooth bottom between adjacent sawtooth forms chip pocket, sawtooth is met in the blade body of the direction of cutting saw-tooth tool bit is installed, the described saw-tooth tool bit dorsad face of the center of circle one side of blade body is end face, the downward-sloping setting of direction that this end face cuts dorsad, described saw-tooth tool bit is met the groove that is provided with indent to a side of the direction of cutting, and the edge of described groove and the side of saw-tooth tool bit are tangent.

Further arrange: described groove is the setting of " U " type.

Further arrange: " U " type R angle of described groove is R2mm～R5mm.

Further arrange: " U " type R angle of described groove is R3mm.

Further arrange: described groove is the setting of " V " type.

Further arrange: the axis of described groove and the radial line of blade body coaxially arrange.

Further arrange: described groove is connected with chip pocket.

By adopting technique scheme, the relative prior art of the utility model is compared to be had: because saw-tooth tool bit is met the groove that is provided with indent to a side of the direction of cutting, the edge of groove and the side of saw-tooth tool bit are tangent, tangent rear saw-tooth tool bit forms the seamed edge of two side direction towards direction one side of cutting, seamed edge can be used as the blade of cutting use, in the time that saw blade rotates, the summit of the blade of seamed edge both sides contacts at first with cutting material, thrust required cutting object, suffered resistance is little, good cutting effect, durable, long service life, can also be convenient to chip removal by groove, better heat-radiation effect.

In figure: 1, blade body; 2, sawtooth; 3, chip pocket; 4, saw-tooth tool bit; 5, groove; 6, end face.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, a kind of saw blade is described further.

A kind of saw blade, comprise blade body 1, be located at the sawtooth 2 on blade body 1 circumference, sawtooth 2 is met in the blade body 1 of the direction of cutting saw-tooth tool bit 4 is installed, on this sawtooth 2, there is a mounting groove of installing for saw-tooth tool bit 4, the bottom of mounting groove is circular arc setting, corresponding, the root of saw-tooth tool bit 4 is to be also circular arc setting, embeds in mounting groove and fixes, and then by welding, saw-tooth tool bit 4 is connected with sawtooth 2.

The saw-tooth tool bit 4 dorsad face of the center of circle one side of blade body 1 is end face 6, the downward-sloping setting of direction that this end face 6 cuts dorsad, saw-tooth tool bit 4 is higher towards direction one side of cutting, saw blade when rotated, first contact with this place, further, saw-tooth tool bit 4 is met the groove 5 that is provided with indent to a side of the direction of cutting, the side of the edge of groove 5 and saw-tooth tool bit 4 is tangent, height point on the end face 6 of saw-tooth tool bit 4 has two summits, there are two seamed edges in the side of Qie Xiao direction, seamed edge can be regarded blade as, when rotated, two summit contact objects of saw-tooth tool bit 4, such as being that cutting is when timber, insert in timber in advance on two summits on saw-tooth tool bit 4, then be further rotated, in two seamed edge incision timber on the side of the direction of cutting, cut comparatively laborsaving.

As saw-tooth tool bit 4 preferably, groove 5 is the setting of " U " type, " U " type R angle of groove 5 is can be within the scope of R2mm～R5mm, R angle is preferably R3mm, this size can form all comparatively suitable saw-tooth tool bits 4 of structural strength, support strength.

The cambered surface of " U " type indent of saw-tooth tool bit 4, in the time of cutting, is dispersed to circular arc everywhere by suffered internal stress and from the extruding force of cutting object, ensures saw-tooth tool bit 4 mean forceds, embodies the reasonability of structure.

Further, the radial line of the axis of groove 5 and blade body 1 coaxially arranges, and the tooth bottom between adjacent sawtooth 2 forms chip pocket 3, and groove 5 is connected with chip pocket 3, in the time of cutting object, form scrap time, can discharge downwards from groove 5 timely, be convenient to chip removal, simultaneously, groove 5 can dispel the heat in time, reduces the temperature of saw-tooth tool bit 4, avoids the higher damage saw-tooth tool bit 4 of temperature.

As the another kind of embodiment of saw-tooth tool bit 4, groove 5 can also be the setting of " V " type, and when groove 5 is " V " type, in cutting, the timely chip removal of same energy and heat radiation, can promote the effect of cutting object simultaneously.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model. It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
