Abstract
The utility model provides a kind of left and right tooth form saw blade, including matrix, sawtooth is arranged in described matrix, the sawtooth includes pitch face, the adjacent pitch face is located at the sawtooth both sides respectively, the adjacent pitch face forms an opening in the orthographic projection in described matrix extending direction plane, and the land of the pitch face and the extending direction of described matrix are angled.The saw blade cutting speed is fast, efficient, sturdy and durable.
Description
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.
Description of the drawings
Fig. 1 is the first viewing angle constructions schematic diagram of the utility model;
Fig. 2 is the second viewing angle constructions schematic diagram of the utility model;
Fig. 3 is the side view of the utility model.
Label in figure is as follows:
1. matrix, 11. grooves, 111. bases, 112. sides, 2. sawtooth, 21. pitch faces, 211. lands, 22. tooth ends.
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.
