Description

A kind of left and right tooth form saw blade

Technical field

The utility model is related to field of hardware more particularly to a kind of left and right tooth form saw blades.

Background technology

The sawtooth of the saw blade of sawing timber is often larger and staggered or the bending of sawtooth end is angled, to keep away Exempt from saw blade and blocked to reduce by timber stock-removing efficiency or saw blade to be caused to damage, the consumption of timber at this time is larger, cutting speed is relatively slow and Cutting speed is low.As soon as when sawtooth is located on a line, the consumption of timber is small in saw blade, in addition sawing quality it is good, it is sharper, saw The bending stress that body is born also smaller, however saw blade is squeezed by both sides timber at this time, frictional force is larger and uneven, causes to saw Tooth is not durable, saw blade is easily damaged.

Invention content

The utility model provides a kind of left and right tooth form saw blade, can improve saw cutting speed and extend the use longevity of saw blade Life.

In order to reach the purpose, the utility model adopts the following technical solution：Including matrix, it is arranged in described matrix Sawtooth, it is characterised in that：The sawtooth includes pitch face, and the adjacent pitch face is located at the sawtooth both sides, adjacent institute respectively State pitch face in described matrix extending direction plane orthographic projection formed opening, the land of the pitch face with it is described The extending direction of matrix is angled.

Sawtooth is located along the same line as a result, the land cut-out lumber fibre of pitch face, the opening formed into pitch face The land chopping that timber in channel is in contact with it in active procedure.

As a preferred embodiment, the sawtooth include tooth ends, along tooth ends described in described matrix extending direction with it is described tiltedly The flank of tooth is separately positioned on the sawtooth both ends.

As a result, when saw blade is mobile and tooth ends are first contacted with timber, sawdust moves under the promotion of tooth ends.

As a preferred embodiment, described matrix includes the groove between the adjacent sawtooth, the groove includes and institute State base and the side between the base and the pitch face that tooth ends are connected.

The sawdust for entering pitch face formation open channel as a result, enters in groove.

As a preferred embodiment, it is seamlessly transitted between the side and the base.

Sawdust is avoided to be stuck between side and base as a result, to come off naturally.

As a preferred embodiment, the angle between the pitch face and the sawtooth side is 7 ° -15 °.

When angle is less than the range as a result, saw blade is easily stuck；When angle is more than the range, saw blade is not sharp enough, cuts It is low to cut efficiency.

As a preferred embodiment, the sawtooth welding is on the matrix.

As a preferred embodiment, the material of the sawtooth is stellite or hard alloy.

As a preferred embodiment, described matrix is frame saw blade matrix or bands for band matrix.

To sum up, compared with prior art, the utility model has the advantage of：Lumber consumption is small in working angles, cutting speed Degree is fast, and efficient, saw blade is durable.

Specific embodiment

The utility model is described in further detail for middle embodiment below in conjunction with the accompanying drawings.

As shown in Figure 1, the saw blade includes matrix 1, matrix 1 can be frame saw blade matrix or bands for band matrix.It is arranged on matrix 1 Sawtooth 2 is shown, sawtooth 2 includes pitch face 21, and adjacent inclined teeth face 21 is located at 2 both sides of sawtooth respectively, as shown in figure 3, pitch face 21 It is alternately arranged, adjacent inclined teeth face 21 forms a v-shaped opening, helical teeth in the orthographic projection in 1 extending direction plane of matrix The land 211 and the extending direction of matrix 1 in face 21 are angled.Sawtooth 2 is located along the same line, when cutting timber, helical teeth Face 21 is first contacted with timber, and the land 211 of pitch face 21 cuts off lumber fibre, in the open channel formed into pitch face 21 The land 211 that timber is in contact with it in saw blade moving process shreds, and avoids saw blade since frictional force is excessive and is stuck, saw Stress is small in use for item, extends service life, improves cutting speed and reduces the lumber consumption during this.

As shown in Fig. 2, sawtooth 2 includes tooth ends 2, it is separately positioned on along 1 extending direction tooth ends 2 of matrix with pitch face 21 2 both ends of sawtooth.When saw blade is mobile and tooth ends 2 are first contacted with timber, sawdust moves under the promotion of tooth ends 2.Matrix 1 wraps Include the groove 11 between adjacent saw-tooth 2, groove 11 include the base 111 being connected with tooth ends 2 and positioned at base 111 and Side 112 between pitch face 21.Saw blade can generate vibration in active procedure, the position small range of tooth ends 2 during being somebody's turn to do Change and the sawdust on its event trace is pushed through in groove 11, sawdust is finally transported to outside timber and voluntarily falls.

It is seamlessly transitted between side 112 and base 111, sawdust is avoided to be stuck between side 112 and base 111 can not be certainly So come off.Angle between 2 side of pitch face 21 and sawtooth is 7 ° -15 °, and when angle is less than the range, saw blade is easily stuck；Folder When angle is more than the range, saw blade is not sharp enough, and stock-removing efficiency is low.

Sawtooth 2 is welded on matrix 1, and the material of sawtooth 2 is stellite or hard alloy, to ensure the hard of sawtooth 2 Degree.

Described above is only the explanation to the utility model so that those of ordinary skill in the art's can completely implements this Scheme, but be not the limitation to the utility model, those skilled in the art can be as needed after this specification is read The modification of no creative contribution is made to the present embodiment, these are all without creative modification, but as long as in this practicality It is all protected in novel right by Patent Law.
