(54) РЕЗЕЦ ПИЛЬНОЙ ЦЕПИ(54) CUTTER CUTTER
1one
Изобретение относитс к пильным цеп м переносных моторных пил и может -быть использовано в лесной промышленности.The invention relates to saw chains of portable chain saws and can be used in the forest industry.
Известен резец пильной цепи, включающий корпус с Г-образным зубом и ограничителемKnown cutter saw chain, comprising a housing with an L-shaped tooth and limiter
П Известен резец пильной цепи, включающий корпус с Г-образным зубом, ограничителем и отверсти ми под шарнирные соединени 2.Known is a saw chain cutter comprising a housing with an L-shaped tooth, a stop and holes for articulated joints 2.
В процессе резани ограничитель известных резцов частично внедр етс в дно пропила , что приводит к увеличению усили резани .During the cutting process, the stopper of known incisors is partially inserted into the bottom of the kerf, which leads to an increase in the cutting force.
Цель изобретени - снижение усили резани . Достигаетс это тем, что передн часть ограничител имеет режущую кромку с углом резани (а), равным 150-170° и углом заточки (р), равным 60-70°.The purpose of the invention is to reduce cutting effort. This is achieved by the fact that the front part of the limiter has a cutting edge with a cutting angle (a) of 150-170 ° and a grinding angle (p) of 60-70 °.
На фиг. 1 изображен резец пильной цени, вид сбоку; на фиг. 2--тот же резец, вид сверху.FIG. 1 shows a saw cutter, side view; in fig. 2 - the same cutter, top view.
Резец -пильной цени включает корпус 1, Гобразный зуб 2 и ограничитель 3, на передней части которого вьшолнена режуща кромка 4 с углом резани (а), равным 150-170° и углом заточки (|3), равным 60-70°.The cutter blade includes a body 1, a shaped tooth 2 and a stop 3, on the front of which the cutting edge 4 is made with a cutting angle (a) of 150-170 ° and a grinding angle (| 3) of 60-70 °.
В процессе резани , в момент внедрени ограничител в дно пропила, усилие резани снижаетс благодар наличию режущей кромки на ограничителе, при этом облегчаетс разрыв волокон и транспортировка стружки в пропиле.During the cutting process, at the moment of insertion of the stopper into the bottom of the cut, the cutting force is reduced due to the presence of the cutting edge on the stopper, thus breaking the fibers and transporting the chips in the kerf is facilitated.
