Description
Изобретение относитс к устройствам дл резани обрабатываемых изделий , например, древесины и может быт использовано в угольной и деревообрабатывающей промышленности. Известно устройство дл резани , например, древесины, включающее два режущих полотна с зубь ми, привод и руко тку 1 , Недостаток за вленного устройства заключаетс в том, что по мере увеличени глубины резани образуютс два реза (каждым режущим полотном отдельно) , оставша с неразрутиенна часть древесины между полотнами вызывает нагревание их до температуры 70-80°С и снижает скорость резани . Целью изобретени вл етс повышение коэффициента полезного действи за счет увеличени скорости рез ни с Поставленна цель достигаетс те что устройство снабжено пластиной, установленной режущими полотнами , зубьк которых симметрично раз заде вы Е противоположные стороны, причем ширина пластины меньше 1шрины полотен, а ее толщина равна рассто нию между концами симметрично разведенных зубьев одного из полотен. На фиг. 1 изображено устройство, общий вил; на фиг. 2 - разрез А-Л фиг. 1. , Устройство дл резани древесины включает режущие полотна 1 и 2 с зубь ми, пластину 3, котора неподвижно крепитс к корпусу 4 устройст.ва , руко тку 5 с пусковым устройством . На пластине установлен штифт 6, служащий направл ющим элементом при перемещении полотен. Полотна одним концом креп тс к ползунам 7, которые соединены пальцами 8 с эксцентриками и через коническую шестерню 9 с кривошипно-шатунным механизмом, а другим концом (на которых имеютс пазы на длину хода полотен) насаживают на штифт 6 по обе стороны пластины. Между полотнами и пластиной образуетс полость 11, глубиной не менее высоты зуба. Устройство работа:ет следующим образом . При включении устройства режущие полотна 1 и 2 совершают возвратнопоступательное движение в противоположных направлени х. При резании дреThe invention relates to devices for cutting processed products, such as wood, and can be used in the coal and woodworking industry. A device for cutting, for example, wood, comprising two cutting blades with teeth, an actuator and a handle 1, is known. A disadvantage of the claimed device is that as the cutting depth increases, two cuts are formed (each cutting blade separately) the part of the wood between the blades causes them to be heated to a temperature of 70-80 ° C and reduces the cutting speed. The aim of the invention is to increase the efficiency by increasing the cutting speed. The aim is to ensure that the device is equipped with a plate, installed cutting blades, the teeth of which are symmetrically separated from the E opposite sides, and the width of the plate is less than 1 width of the blades. between the ends of symmetrically divorced teeth of one of the canvases. FIG. 1 shows the device, a common fork; in fig. 2 shows a section A — L of FIG. 1. A device for cutting wood includes cutting blades 1 and 2 with teeth, a plate 3 which is fixedly attached to the housing 4 of the device, a handle 5 with a starting device. A pin 6 is installed on the plate, which serves as a guiding element when moving the webs. The blades are fastened at one end to the sliders 7, which are connected by fingers 8 with eccentrics and through bevel gear 9 with a crank mechanism, and the other end (on which there are grooves for the length of the webs) is mounted on pin 6 on both sides of the plate. A cavity 11 forms between the blades and the plate, with a depth of at least the height of the tooth. Device operation: em as follows. When the device is turned on, the cutting blades 1 and 2 make a reciprocating movement in opposite directions. When cutting wood
