Description

Изобретение относитс к лесопильной и деревообрабатывающей промышленности.The invention relates to the sawmill and woodworking industries.

Известен ленточнопильный станок, включающий станину, ведущий и ведомые шкивы , поворотный рычаг, шарнирно соеаинен- ный с опорой веаомого щкива, перемещаемой по направл ющим при помощи винтового механизма, пневматический амортизатор и привод (l .A band saw machine is known, which includes a frame, leading and driven pulleys, a pivot arm hingedly connected with the support of a wide scraper moved along the guides by means of a screw mechanism, a pneumatic shock absorber and a drive (l.

Недостаток данного станка - громозд- кость конструкции иэ-за расположени вала ведомого шкива на двух опорах.The disadvantage of this machine is the bulkiness of the design due to the location of the driven pulley shaft on two supports.

Наиболее близким к предлагаемому &л етс ленточнопильный станок, включающий станину, смонтированные нв валах ведомый и ведущий шкивы с установленной на них аильной лентой, механизм ее нат жени с перемещаемой по направл ющим кареткой, на которой консольно смонтирован вал ведомого щкива, механизм перемещени каретки и привод 2 .The closest to the offer is a band saw machine, including a frame, mounted and driven pulleys in shafts with an aiyl tape mounted on them, a mechanism for tensioning it from a carriage moved along a guideway, on which a driven shaft is mounted, a mechanism for moving the carriage and a drive 2

Цель изобретени - упрощение конструкции и уменьшение габаритов стпика,The purpose of the invention is to simplify the design and reduce the size of the stitch,

UJis этого вал ведомого шкива выполнен полым и установлев на каретке при UJis this driven pulley shaft is hollow and installed on the carriage when

На фиг. 1 показан предлагаемый станок , общий вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 2.FIG. 1 shows the proposed machine, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

Ленточнопильный станок содержит станину 1, смонтированные на валах 2 н 3 соответственно ведущий 4 и ведомый 5 шкивы, механизм нат жени 6 пилы 7 с подвижной кареткой 8 и привод 9 шкивов Каретка может перемещатьс в направл иощих 1О при помощи, например, гидроцн- линдра 11.The band saw machine contains frame 1 mounted on shafts 2 and 3, respectively, leading 4 and driven 5 pulleys, tensioning mechanism 6 saws 7 with movable carriage 8 and driving 9 pulleys. The carriage can move in directions 1O using, for example, hydraulic cylinder 11. .

Вал 3 ведомого шкива 5 консольно смонтирован на каретке 8 при помощи сферической цапфы 12. Внутри врла 3 закреплен стакан 13, в котором раомещв- на головка 14 цапфы между двум вкладышами 15 к 16. Друтхэй конец 17 цапфы закреплен на каретке 8 механизма нат жени 6.The shaft 3 of the driven pulley 5 is cantilevered mounted on the carriage 8 by means of a spherical pin 12. Inside the time of the barrel 3 is fixed the cup 13, in which the head 14 of the pin is between two inserts 15 to 16. The druthey end of the 17 pin is fixed on the carriage 8 of the tension mechanism 6 .

Claims

The shaft 3 of the driven pulley 5 with the help of the gig 18 rests on the carriage 8. One of the ends g 18 of the hinge is connected to the ox 3 of the upper pulley 5, and its other end is threaded and screwed into the support nut 19, which is also attached to the carriage 8 . Works as a grinding machine as follows. When the working fluid is pumped into the piston section of the hydraulic cylinder 11, its rod extends and mixes the carriage 8 in the right angle with 1O, and the tension of the saw 7 is achieved. To implement the driven pulley 5, in order to ensure a stable position of the saw 7 on the bars 4 and 5 The ha 18 is screwed (turned out) into the nut 19, the shaft 3 of the pulley 5 being rotated on the head 14 of the spherical pin 12 and the pulley is inclined. Placing a pin inside the shaft of the driven pulley significantly reduces the overall width of the machine, since the pin, located with the main bearing of the driven pulley, is located inside the shaft. Performing the same head spherical spherical. The ski allows the pulley to be tilted by simple means — tight with one at one of its ends. Claim banding machine, including a frame, mounted on the shafts driven and; Driving pulleys with a saw tape mounted on them, its tension mechanism with a slide carriage moved along the guide rail on which the driven pulley shaft is mounted, the movement mechanism of the carriage and the drive, that, in order to simplify the design and reduce the dimensions of the machine, the driven pulley shaft is hollow and mounted on a carriage with a spherical pin mounted in the shaft cavity.
