Description
Technical field
The utility model belongs to bands for band manufacture field, and in particular to a kind of to divide tooth mould for band saw blade tooth dividing.
Background technology
At present, it is more to divide tooth form bi-metal bandsaw blades on domestic market.Traditional bi-metal bandsaw blades mode of production
For welding, mill teeth, divide tooth, heat treatment.Because the bands for band after mill teeth is that soft state is not quenched, is tempered, therefore carried out again after tooth is divided
Heat treatment, crown divides tooth amount to have certain change, along with bands for band has certain elongation percentage, therefore band after quenching, being tempered
Saw blade can occur point phenomenon that tooth amount is unilateral or symmetry is bad to a certain extent.Divide tooth amount to be also referred to as saw kerf width, divide tooth
The problems such as the unstable of amount can affect to the workpiece of cutting, such as cut oblique, coring, and section is coarse.
At present, based on the main soft point of tooth of band saw blade tooth dividing, i.e., a point tooth is carried out before quenching, being tempered.Reheating after such a point of tooth
The shortcomings that processing mode, mainly divides the symmetry of tooth amount can be in various degree by certain influence, and is unfavorable for ensureing that workpiece is cut
The roughness of section.Because tooth material is HSS steel wires, therefore weld seam and cutting direction keeping parallelism, required divides tooth mould as used
Horizontal sliding mode（See Fig. 1）, then a point tooth could be completed by needing to apply larger power, and the resilience divided after tooth is larger, causes a point tooth amount ripple
Move and without torsion angle, be unfavorable for cutting.
Utility model content
The purpose of this utility model is in view of the shortcomings of the prior art, there is provided one kind divides tooth amount stable and can form torsion
Tooth mould is divided at angle.
The technical solution of the utility model is：It is a kind of to divide tooth mould, including body, the body bag for band saw blade tooth dividing
Include two be parallel to each other and with the clamping face of horizontal plane, be provided between two clamping faces to body exterior inclined the
One working face and to inclined second working face of body interior；First working face and the second working face intersect, intersection structure
Into strike rib CD, the base AB of the strike rib CD and the first working face between angle theta be 15 ~ 45 °, the strike rib CD and
Angle α between horizontal plane is 15 ~ 45 °, and the angle β between strike rib CD projections in the horizontal plane and clamping face is 88
~90°。
Wherein, tilted to body exterior and refer to from top to bottom gradually to outer body extend from the first working face；To body
Inner inclination refers to that the second working face gradually extends to intrinsic direction from top to bottom.
The base AB and plane-parallel, base AB and strike rib CD minimum range δ are 0.2 ~ 0.8mm.
The angle theta and angle α it is equal in magnitude.
The body is 11 ~ 13mm in the size H1 of short transverse, to ensure to divide the stability of tooth.
The body is 13 ~ 15mm in the size H2 scopes of length direction, to meet to divide the size of tooth amount.
It is a kind of that including tooth is divided on a left side and/or tooth is divided on the right side using the above-mentioned bands for band for dividing tooth mould to produce, the left side divide tooth and/
Or the right side divides the windup-degree γ of tooth to be 3 ~ 20 °, preferably 5 ~ 10 °.
In the utility model, angle theta scope is 15 ~ 45 °, oblique angle will be designed here as, primarily to avoiding weld seam
Position；
δ scopes are 0.2 ~ 0.8mm, and this position height is that this can highly ensure not apart from the height of weld seam at rake face
Injure weld seam and roller seating space of not damaging, and effective travel windup-degree；
Angle β scopes are 88-90 °, and this angle is avoided causing tooth material and divides the collision of tooth mould to form torsion angle；
Angle α scope is 15-45 °, will be designed here as oblique angle, can avoid the position of weld seam, it is preferable that is kept with θ
Unanimously；
Angle γ scopes are 3-20 ° and referred to during tooth is divided, when dividing tooth mould strike backing, δ opening positions, to divide tooth mould
The point contacted with backing is fulcrum, the torsion of generation, the angle of formation.
Compared with prior art, the utility model has following advantageous effects：
（1）The contact area with backing is reduced during point tooth, reduces a point tooth pressure, avoids returning for point tooth amount
Bullet.Divide tooth mould using horizontal sliding, it is ensured that divide the quality of tooth, divide tooth mould to ensure to carry out strike backing below position while welding
Acted so as to complete a point tooth.But the lower section of weld seam is proximate to, the width of backing is wider, and is hit using this width as fulcrum,
Formed and effectively divide tooth amount, then required torque is bigger, and in the case where dividing tooth amount certain, then required power is got over
Greatly.Due to the influence of active force and reaction force, after dividing tooth, backing has a certain degree of resilience, and reaction force is bigger, resilience
It is bigger.
（2）Torsion angle γ is formd after dividing tooth, can be advantageous to cut, cutting section is smooth.It is oblique using the utility model
Push type divides tooth mould, due to dividing the design of tooth mould to be with any at crown rake face for torsion point, therefore divides tooth in acquisition
While amount, certain windup-degree is similarly obtained.Without torsion angle saw blade in working angles, each tooth and work
The position of part contact can be regarded as with a contact workpiece, and the tooth material with torsion angle contacts in working angles with workpiece
That can regard as with linear contact lay workpiece, so as to ensure each tooth can effective cutting workpiece, and in the superposition of cutting
During form good section.
（3）Divide the position of tooth by adjustment, can obtain and arbitrarily divide tooth lateral angles, and crown will not be caused to damage.
Adjustment divides the position of tooth, i.e. adjustment divides remote, short range degree of the tooth mould with backing contact site apart from position while welding.Dividing, tooth amount is certain
In the case of, nearer apart from position while welding, what is obtained divides tooth angle degree bigger, conversely, smaller.Therefore as long as control divides tooth mould not
With bead contact, the weld seam zone of influence is avoided, the damage of crown would not be caused.
