Description
Technical field
The present invention relates to a kind of sawing metal knifes, and in particular to a kind of carbide bit, the band saw comprising the cutter head
Item and the electrode cooperated with the cutter head.Present invention is mainly applied to hard alloy band saw blades.
Background technique
For hard alloy band saw blade in sawing process, stock removal is to have to consider the problems of at present.Traditional welding side
Method needs to consider the problems of weld strength in tip size design by the way of brazing, therefore under normal circumstances, cutter head
Size design is bigger than normal, this is unfavorable for grinding.With the development of welding technology, carbide surface can be carried out at present
Nickel plating, cobalt plating carry out electric resistance welding, and welding quality is further developed.In order to towards be more conducive to hard alloy mill
The direction cut, to the design of carbide bit, it is very important, on the one hand can guarantee weld strength, on the other hand again
It can be reduced the stock removal of hard alloy.
At present in hard alloy band saw blade manufacturing process, the shape of carbide bit be mainly ball, cylinder (see Fig. 1,
Fig. 2), carpenter's hard alloy band saw blade also uses rectangle, and the cutter head of these types of type needs after welding to cutter head
It is ground, completes required cutting edge and tooth form and subsequent processing.Under equal conditions, the stock removal of ball is to be less than cylinder
Stock removal, from the point of view of overall situation, the stock removal of the two is all bigger, for the control of grinding accuracy, skive
Consumption is all unfavorable.Rectangular stock removal is bigger.
From the point of view of the hard alloy band saw blade product in the current whole world, two major classes are broadly divided into, first is that dividing flute profile bands for band
(Set Style), one is regardless of flute profile bands for band (Nonset Style).For dividing flute profile and regardless of flute profile hard-metal strips
Saw blade, usual way be divide flute profile weld ball, regardless of flute profile weld cylinder, but the machining allowance of two kinds of alloy cutter heads,
Processing efficiency is all detrimental to hard-alloy grinding.
Summary of the invention
The problem to be solved in the present invention occurs that stock removal is big, processing efficiency when being for the welding of hard alloy band saw blade cutter head
Low, the problems such as weld strength is insufficient, provide a kind of cutter head for being welded in bands for band tooth support.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: one kind is for being welded on bands for band tooth support
Cutter head, define perpendicular to cutter head thickness direction cutter head section be cutter head cross section；
The cutter head cross section by first straight line section, second straight line section, the first arc section for being contacted with tooth support, with the
The second arc section that one arc section is oppositely arranged surrounds；
One end of first arc section, the other end connect with one end of one end of first straight line section, second straight line section respectively
It connects；
One end of second arc section, the other end respectively with the other end of first straight line section, second straight line section it is another
End connection；
Second arc section is raised to the side far from the first arc section.
It, can by setting above-mentioned shape for cutter head in the present invention compared to original ball or the cutter head of cylindrical shape
To reduce specific surface area, in same weld current parameters, scattering and disappearing for ball heat is reduced, guarantees weld strength, is reduced
Grinding allowance promotes grinding efficiency.By the way that the second arc section is arranged, sweating heat can be reduced to the part in welding
Burning effect, the embrittlement when part will not lead to roll flute because of sweating heat after welding.Applicant research when find, if
Electrode and cutter head are designed to pointed shape, form point-to-point contact, and electric current passes through from point of a knife, and current density is big, it is easy to
Cause the scaling loss of tooth tip, to occur the phenomenon that cutter head tipping in roll flute.By the way that the second arc section, and mating band arc is arranged
Electrode reduce the current density passed through from point of a knife so that contact of the forming face with face between electrode and cutter head, reduce tooth tip and burn
The risk of damage.
Further, it is connected with third arc section between one end of first arc section and one end of first straight line section,
The other end of first arc section and one end of second straight line section are connected with the 4th arc section.
By the way that third arc section, the 4th arc section is arranged, to carry out circular arc processing to the wedge angle in cutter head, closed in hard
The risk of hard alloy damage is reduced during the die sinking of golden cutter head.
Further, the radius for enabling the third arc section is R3, the 4th arc section radius be R4, then 0.05mm≤R3
≤ 0.15mm, 0.05mm≤R4≤0.15mm。
