Abstract

The utility model discloses a kind of bands for band for high speed high-rate cutting, including saw blade body and crown, the crown includes anterior angle first relief angle adjacent with anterior angle and the second relief angle below the first relief angle, first relief angle is less than the anterior angle, and second relief angle is much larger than the anterior angle.The utility model is adapted to high-speed cutting, high-rate cutting, is the special bands for band of the following material of sawing medium carbon steel.Sawing efficiency and service life can be effectively improved.

Description

For the bands for band of high speed high-rate cutting

Technical field

The utility model is related to a kind of bands for band for high speed high-rate cutting.

Background technology

Production bands for band is wide in variety now, mainly pays attention to cutting sharp.It has the disadvantage：For high-rate cutting and high efficiency Cutting, easily causes and beats tooth and difficult cutting.

Utility model content

Problem to be solved in the utility model be to provide it is a kind of effectively improve sawing efficiency and service life at a high speed The bands for band of high-rate cutting.

In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：For the band of high speed high-rate cutting Saw blade, including saw blade body and crown, the crown include anterior angle first relief angle adjacent with anterior angle and under the first relief angle Second relief angle of side, first relief angle is less than the anterior angle, and second relief angle is more than the anterior angle.

First relief angle is 5~7 °.

Second relief angle is 45 °.

The anterior angle is 11~13 °.

The utility model is adapted to high-speed cutting, high-rate cutting, is the special bands for band of the following material of sawing medium carbon steel.Can be with Effectively improve sawing efficiency and service life.

Brief description of the drawings

Fig. 1 is the sawtooth partial enlarged drawing of the utility model bands for band

Specific embodiment

As shown in figure 1, for the bands for band of high speed high-rate cutting, including saw blade body 1 and crown 2, the crown includes Anterior angle first relief angle adjacent with anterior angle and the second relief angle below the first relief angle, first relief angle is less than before described Angle, second relief angle is more than the anterior angle.

For the bands for band of high speed high-rate cutting, its cutting principle, one is the sharpness that anterior angle determines cutter, and anterior angle is The angle that throat of tooth line and tooth line high are formed, anterior angle is not too small sharp, it is not easy to penetration of a cutting tool, and anterior angle θ is designed between 11~13 °； Two is relief angle using double relief angles, and relief angle is increment line and the angle folded by tooth back line, and the first relief angle α 1 is designed as 5~7 °, to reduce Frictional force, the second relief angle α 2 is designed as 45 °, iron filings is easily disconnected and into web-like.Bands for band cutting is multiple tooth simultaneously participates in, The even complex process compound to lower feeding, continuous cutting, each tooth is again interrupted cut.In order to adapt to high-rate cutting, keep cutting Cut power uniformly, the tooth pitch t designed between the crown of two neighboring sawtooth is identical, and h high is also identical for tooth.

Design parameter：Anterior angle θ is designed as 11~13 °；5 teeth are one group, and point tooth of tooth 1~5 is that (R, L, M distinguish for R, L, R, L, M Represent left and right point tooth and orthodont)；First relief angle α 1 is designed as 5~7 °, and the second relief angle α 2 is designed as 45 °；Circular arc r be 2.5~ 4.5mm；Depending on tooth pitch t and tooth h high is according to how many teeth of per inch.

The utility model bands for band is mainly the cutting anterior angle and double relief angles of control bands for band, increases tooth form width, it is ensured that The bearing capacity of tooth in high-rate cutting, is mainly used in the high speed high-rate cutting below 45# materials, it is also possible to instead of circular saw Cutting, cutting speed is enhanced about more than once up to 150m/min, stock-removing efficiency.

Claims

1. the bands for band of high speed high-rate cutting, including saw blade body and crown are used for, it is characterised in that the crown includes preceding Angle first relief angle adjacent with anterior angle and the second relief angle below the first relief angle, first relief angle are less than the anterior angle, Second relief angle is more than the anterior angle.

2. bands for band according to claim 1, it is characterised in that first relief angle is 5~7 °.
