Description

Spiral saw blade

Technical field

The utility model relates to a kind of saw blade, particularly relates to a kind of spiral saw blade of promoting cutting rate, increasing the service life, reduce noise and raising precision effect.

Background technology

Referring to shown in Figure 1, saw blade 10 in the past mainly has a blade body 11 and several sawtooth 12, blade body 11 is slightly in the form of annular discs, its centre is equipped with an axis hole 111, this axis hole 111 can be for a driving shaft (figure does not show) installing, can drive whole saw blade 10 whereby rotates, several sawtooth 12 are arranged on the outer peripheral edges place of blade body 11, all be provided with a sawing blade 121 that is straight bulk on each sawtooth 12, after saw blade 10 rotates, utilize 121 pairs of workpiece of sawing blade (figure does not show) to cut, above-mentioned saw blade 10 has the cutting function really, yet still have its disappearance to exist in the use, the sawtooth 12 of saw blade 10 was straight block-shaped sawing blade 121 owing to what adopt in the past, sawing blade 121 is with the face way of contact with workpiece, the normal stress that produces is quite big, sawing blade 121 is caused sizable load, be easy to generate noise when therefore cutting, workpiece also can reduce processing quality and precision because shaking the cutter influence, the service life of this kind saw blade 10 usually can be not oversize, and the cutting rate of this saw blade 10 is slow, and process time is longer, can't effectively improve speed of production.

Referring to shown in Figure 2, also had another kind of saw blade 20 structures in the past, this saw blade 20 has a blade body 21 and most the sawtooth 22 that are located at place, blade body 21 neighborings, each sawtooth 22 is formed with the basil 221 that inclines in the place, side, and the symmetrical shape that the basil 221 that inclines of adjacent sawtooth 22 interlocks about being, sawtooth 22 structures of ramp type whereby, can make saw blade 20 more swimmingly workpiece be cut, though above-mentioned saw blade 20 can allow sawtooth 22 obtain more smooth-going cutting effect by the basil 221 that inclines really, but this sawtooth 22 is a kind of sharp-tooth shaped structures, this kind structure is when bearing cutting stress, allow sawtooth 22 burst apart easily and damage, therefore still can't effectively promote whole cutting rate.

The utility model content

The utility model purpose is to provide a kind of promotes cutting rate, increase the service life, reduce noise and improve the spiral saw blade of precision effect.

The utility model provides a kind of spiral saw blade, it includes a blade body, this blade body centre is equipped with an axis hole, blade body is provided with a group sawtooth group along the periphery, it is characterized in that: the sawtooth group is made of several first sawtooth and the mutual wrong row of several second sawtooth, first, the second sawtooth periphery all be provided with one in the shape of a spiral to blade part, at least be concaved with two roads, first chip-breaker on the blade part of first sawtooth, at least be concaved with together second chip-breaker on the blade part of second sawtooth, the position of second chip-breaker just be corresponding in the middle of first chip-breaker in twos the place.

Spiral saw blade described in the utility model, first, second sawtooth all is provided with a side edge portion in a side edge.

The beneficial effects of the utility model are: utilize first, second sawtooth that the blade part of screw is set, and be concaved with chip-breaker on blade part, reach the work effect of promoting cutting rate, increasing the service life, reducing noise and raising precision whereby.

The specific embodiment

Aforementioned and other technology contents, characteristics and effect about the utility model, below cooperate in the explanation with reference to graphic and a preferred embodiment, can clearly present, the spiral saw blade of the utility model will be elaborated below by most preferred embodiment and accompanying drawing.

Extremely shown in Figure 5 referring to Fig. 3, the spiral saw blade of the utility model is in a preferred embodiment, include a blade body 30, these blade body 30 centre are equipped with an axis hole 31, this axis hole 31 can be for driving shaft of installing (figure does not show), blade body 30 is provided with a group sawtooth group 40 along the periphery, the utility model improvement focuses on:

Sawtooth group 40 is made of several first sawtooth 41 and several second sawtooth 42 mutual wrong rows, first,

second sawtooth

41,42 peripheries all be provided with one in the shape of a spiral to blade part 411,421, first sawtooth 41 is concaved with three roads, first chip-breaker 412 on blade part 411, second sawtooth 42 is concaved with two roads, second chip-breaker 422 on blade part 421, the position of each road second chip-breaker 422 just be corresponding in the middle of first chip-breaker 412 in twos the place, whereby when first,

second sawtooth

41,42 when cutting, first, second chip-breaker 412, but 422 comparatively dense ground carry out the chip breaking effect, in addition, first,

second sawtooth

41,42 all are provided with a side edge portion 413 in a side edge, 423.

More than be the general introduction of the spiral saw blade member of the utility model shape, then, effect statement as the back that stock removal action of the present utility model and expection can be reached again:

Referring to shown in Figure 6, when the user will use the utility model that one workpiece 100 is cut, utilize blade part 411,421 machinables to go out the peripheral shape of workpiece 100, utilize 413,423 machinables of side edge portion to go out the side fillet position of workpiece 100, whereby the utility model swimmingly cutting go out groove structure.

Referring to shown in Figure 7, when the user will carry out bilateral cutting to workpiece 100, can adopt two groups of hands of spiral to be 1,2, two groups of saw blade 1,2 one the first from left of symmetrical saw blade and not part on the right side and can cut, but cutting goes out to be the bilateral groove shapes of symmetry shape whereby workpiece 100 dual-sides.

In sum, the spiral saw blade of the utility model mainly is to design in order to promote cutting rate, its technological means that adopts be the blade body mutual stagger arrangement in 30 peripheries be provided with first sawtooth 41 and second sawtooth 42, first,

second sawtooth

41,42 be provided with in the shape of a spiral to blade part 411,421, when workpiece is cut, cutting stress can be along blade part 411,421 the hand of spiral is disperseed, whole load is quite light, not only can reduce the generation of noise, prolong the service life of saw blade, more can improve cutting rate effectively, accelerate to make speed of production, and use the utility model to be difficult for producing the cutter that shakes, can significantly promote the processing precision, so the utility model has excellent work effect really.
