The utility model discloses an every tooth of saw bit make full use of carries out cutting process, has improved machining efficiency at double.
Description
Technical field
The utility model relates to sintered carbide tools field, is specifically related to a kind of PCD saw blade with double-surface cutting function.
Background technology
Polycrystalline diamond (PCD) saw blade due to its have hardness high, cut sharp, the nonabradable advantage of sawtooth, be widely used in the section steel cutting aspect such as fracture morphology and cutting effect being had to comparatively strict requirement.But current saw blade tip is often former single scribe structure, as: there are 12 left helical teeth and 12 right helical teeth in 24 tooth list line cutter heads, when saw blade is in running order, actual is that the tip portions of 12 helical teeth is at rapidoprint effectively, because the side processing of monocline tooth is less than material, cause certain waste, and work is steady not, and the room for promotion of stock-removing efficiency not yet makes full use of.
Utility model content
In view of this, the utility model provides a kind of PCD saw blade with double-surface cutting function, is intended to the operating efficiency improving saw blade.
The technical solution adopted in the utility model is specially:
A kind of PCD saw blade with double-surface cutting function, comprise matrix and cutter head, the center of described matrix is provided with installing hole, and the outer rim of described matrix is evenly distributed with several broached-tooth designs, described cutter head is installed on each described broached-tooth design by the mode of soldering, and described cutter head is double-side cutting cutter head.
Have in the PCD saw blade of double-surface cutting function above-mentioned, the cutting edge of described double-side cutting cutter head is concave arc line, and the arc chord angle at the minimum point place of described concave arc line is 160 ~ 175 °.
Have in the PCD saw blade of double-surface cutting function above-mentioned, described double-side cutting cutter head is concave arc structure, and the arc chord angle at the minimum point place of described concave arc line is 170 °.
Have in the PCD saw blade of double-surface cutting function above-mentioned, the anterior angle of described double-side cutting cutter head is 6 ~ 10 °.
Have in the PCD saw blade of double-surface cutting function above-mentioned, the anterior angle of described double-side cutting cutter head is 8 °.
Have in the PCD saw blade of double-surface cutting function above-mentioned, the relief angle of described double-side cutting cutter head is 10 ~ 15 °.
Have in the PCD saw blade of double-surface cutting function above-mentioned, the relief angle of described double-side cutting cutter head is 13 °.
The beneficial effect that the utility model produces is:
PCD saw blade design of the present utility model is the two-sided equal U-shaped toothing that can participate in cutwork of cutter head, left helical teeth and right helical teeth are combined into a kind of profile of tooth, combine the advantage of left and right tooth, make full use of each tooth and carry out machining, working angles is uniform and stable more, cutting effect that the 24 rack saw sheets pointed out in background technology as completed with the structure of 12 teeth just can complete.
