Abstract

The utility model discloses a band saw blade for tooth-shaped steel, which comprises a saw blade (2), an integral tooth (1) is structure at the same position by a left sticking tooth and a right sticking tooth, the anterior angle (Gamma) of all integral tooth is from 10 degree to 15 degree while a first clearance angle (a) is from 35 degree to 40 degree; a second clearance angle (a<2>) is formed on the integral tooth, which is from 10 degree to 15 degree. The utility model has the advantages of long lifecycle.

Description

Whole profile of tooth steel bands for band

Technical field

The utility model relates to saw blade, especially relates to a kind of whole profile of tooth steel bands for band.

Background technology

At present, traditional saw blade structure comprises that hand is used, machine usefulness, all is to pull out tooth (as Fig. 1, Fig. 2, shown in Figure 3) about the sawtooth blade, to reach the principle that forms swage set, reduces friction and carries out machining.Traditional rack saw road of pulling out approximately is divided into 3 kinds: 1, the staggered rack saw road of pulling out; 2, the middle staggered rack saw road of pulling out; 3, waveform pulls out the rack saw road, but above-mentioned these saw blades about pull out the in a single day a certain odontotripsis that pulls out of tooth and just can't carry out work, thereby whole saw blade is lacked service life.

The utility model content

The purpose of this utility model provides a kind of whole profile of tooth steel bands for band of long service life.

In order to achieve the above object, the utility model adopts following technical scheme: a kind of whole profile of tooth steel bands for band, comprise saw blade, and the left and right tooth that pulls out of saw blade forms whole tooth at the saw blade same position, the anterior angle of described whole tooth is 10-15 °, and first relief angle is 35-40 °; Whole tooth also is formed with second relief angle, and described second relief angle is 10-15 °.

The toothing that pulls out that the utility model is produced traditional handicraft (go forward by saw blade, the back forms a left side, tooth is pulled out on the right side) change over whole shape swage set, pull out tooth about before and after being about on traditional saw blade and make on the same position of saw blade, to form whole shape swage set into, and the traditional relatively swage set that pulls out toothing of the width of whole swage set does not change, and whole shape swage set does not just pull out tooth processing, and adopt whole machine-shaping, it is 2 times that tradition is pulled out the rack saw bar that actual cutting is renderd a service, when the acute bar of this spline structure pulls out tooth wearing and tearing is arranged, again the back of sharpening second relief angle, whole saw blade can continue to use, and has increased service life.In addition, the anterior angle of whole tooth (cutting angle) is 10-15 °, and first relief angle is 35-40 °, and from cutting principle, stock-removing efficiency improves; Whole tooth also is formed with second relief angle (but second relief angle of sharpening), and described second relief angle is 10-15 °, and the saw blade of this angle structure can sharpening 4 times, and under equal conditions, the utility model has improved 8 times of service lifes than like product.

The specific embodiment

A kind of whole profile of tooth steel of the utility model is with the structure of bands for band such as Fig. 3, Fig. 4, Fig. 5, shown in Figure 6: the left and right tooth that pulls out of saw blade 2 forms whole tooth 1 at the saw blade same position, and the anterior angle γ of described whole tooth is 10-15 °, and the first relief angle a is 35-40 °; Whole profile of tooth also is formed with the second relief angle a ₂, the described second relief angle a ₂Be 10-15 °.Described anterior angle is the whole front flank of saw blade and perpendicular to the formed angle of the straight line of machined surface, described relief angle is the whole tooth back of saw blade and perpendicular to the formed angle of the straight line for the treatment of worker's face, the utility model changes over whole shape swage set with the toothing that pulls out of traditional mode of production, do not pull out tooth processing, adopt whole machine-shaping, blade adopts the material of high speed steel W 6Mo5Cr4V2, the material of matrix adopting 50CrMnV, adopt the high energy welding procedure to carry out the heat treatment and the thermo-chemical treatment of standard, and blade carried out self-lubrication treatment, steel is improved 3-4 times of service life with bands for band.

Claims

1, a kind of whole profile of tooth steel bands for band comprises saw blade (2), it is characterized in that: the left and right tooth that pulls out of saw blade forms whole tooth (1) at the saw blade same position, and the anterior angle of described whole tooth (γ) is 10-15 °, and first relief angle (a) is 35-40 °; Whole tooth also is formed with the second relief angle (a ₂), the described second relief angle (a ₂) be 10-15 °.
