Description

I. , ..--,Изобретение относитс к лесной И деревообра батывающей промышленност м, в частности, к режущим инструментам дл поперечного резани древесины.I., ..--, The invention relates to the timber and wood processing industries, in particular, to cutting tools for transverse cutting of wood.

Известен пильный даГск, состо щий из корпуса , резцов со скалывающими И подрезающими кромками (1Ь :Known saw DAGSK, consisting of a body, cutters with chipping and undercutting edges (1b:

Известен также гиетьный диск, содержащий-спиралевидный корпус с расположенными на нем резцами , каждый из которых выпол ей в виде боковых подрезающих элементов, между которыми расположен скалывающий элемент с режущей кромкой 2Also known is a wedge disk containing a spiral-shaped body with incisors located on it, each of which is performed in the form of lateral undercutting elements, between which there is a shearing element with a cutting edge 2

Недостатком известных пильных дисков вл етс низкое качество pacrafflOBKH И высокое усилие резани ..A disadvantage of the known saw blades is the poor quality of the pacrafflOBKH and the high cutting force ..

Целью изобретени вл етс повьдаенн качества распиловки и снижение усили резани .The aim of the invention is to improve the quality of sawing and reduce the cutting force.

Это достигаетс тем, что режущие кромки скалывающих элементов расположены поочередно ; правым и левым уклоном к боковой поверхности корпуса, а между резцами на корпусе вьию йены скбсй на всю толщину с наклоном поочередно в противоположные стороны, причем кажThis is achieved by the fact that the cutting edges of the shear elements are arranged alternately; right and left slope to the lateral surface of the body, and between the incisors on the body of the body and the yen, the entire thickness is inclined alternately in opposite directions, each

дай скрс корпуса налравлён под вёрщину скалывающего элемента.Give skrs casing sent under the cleavage of the cleavage element.

На фшг. 1 изображен пильный диск, вид сбоку на фиг. 2 - расположение резцов на корпусе; на фиг. 3 - вид на резцы сбоку; на фиг. 4 - сече1ше А-А на фиг. 3.On fsgg. 1 shows a saw blade, a side view of FIG. 2 - the location of the incisors on the body; in fig. 3 - side view of the incisors; in fig. 4 is a section A-A in FIG. 3

Claims

The saw disk consists of a casing 1 of the spiral shape, 1 cutters are fixed evenly on the barrel 2. Fastening the cutters 2 with the body 1 1 out of length with the help of 3 clips 3. In the cutters 2 there are grooves 4 that cover the body 1 of its width, and in the latter are made of for fixing the incisors on them

2. Each cutter is equipped with two symmetrically located but & reaj {and elements 5 and dropping elements 6, the cutting edges of which 7 are polyenes alternating left and right alternately. Between the cutters 2 on the case 1, the bevels 8 and 9, which have a slope in the Chess order, are made on its entire thickness. In this case, each bevel is directed under the tip of the shear element 6. The saw blade is mounted next to the sawing cut 10, and between the teeth 2 there is a chip 11 with a cross section {12). The work of the saw blade. Each shear element b separates the AND chip from the sawed-off rifle 10, which is pre-cut across the width of the cutting elements S. The chip 11 is directed downward with the front bevel edge of the bar element b iL resting against the bevel 9 of the housing 1, slides towards the lipotinna wall , and is drawn into the gap between the surfaces of the body 1 and the cutting planes. The size of the gaps is somewhat larger than the thickness of the chips. The saw blade provides operative cutting on the xojiy driving whip, which increases the line's performance. Claims of the invention Пш1ЬН1 | 1st disk, including a spiral-shaped body with a cutter located on it. 3

674895 t, each of which is made in the form of lateral undercutting elements, between which there is a shearing element with a cutting edge, characterized in that, in order to increase the quality of sawing and reduce the cutting force, the cutting edges of the shearing elements are alternately arranged with right and left slopes to the side surface of the body, and the mechsdu cutters on the body are made with bevels at full thickness with a slope alternately in opposite directions, with each bevel of the body directed to the top of the shear element.
