Изобретение относитс  к лесот1льной ; промышленности.This invention relates to forest management; industry.

Известен механизм резани  лесопильной рамы, соцержаший пильную рамку с рычажной подвеской 1 .A known mechanism for cutting a saw-frame, a socceded saw frame with a lever suspension 1.

Известен механизм резани  лесопильной рамы, содержащий пильную рамку с подвеской, Выполненной в виде верхней и нижней пар однозвенных рычагов, шарнирно прикрепленных к станине, причем верхн   пара рычагов св зана с верхней поперечиной пильной рамки, а нижн  , через шатуны кривошипно-шатунного привода пильн.ой рамки - с нижней ее поперечиной 2.A sawing frame cutting mechanism is known, which contains a saw frame with a suspension made in the form of upper and lower pairs of single-link levers hinged to the frame, the upper pair of levers being connected to the upper cross-frame of the saw frame, and lower through rods of a crank-connecting rod drive saw. oh frame - with its lower cross member 2.

Недостаток такого устройства заключаетс  в том, что в крайних положени х пильной рамки траектори  ее движени  отридательно вли ет на эффективность процесса пилени .The disadvantage of such a device is that, in the extreme positions of the saw frame, its trajectory has a negative effect on the efficiency of the sawing process.

Цель изобретени  - повышение эффективности ПИЛЕНИЯ.The purpose of the invention is to increase the efficiency of PILING.

Указанна  цель достиг тс  тем, что в механизме резани  верхн   поперечинаThis goal is achieved by the fact that in the cutting mechanism the upper cross member

пильной рамки снабжена дополнительной парой рычагов, при этом обе верхние пары рычагов св заны с верхней поперечиной посредством коромысел, щарнирно установленных на ее пальцах, а каждый шатун привода имеет дополнительное плечо, с которым св зан один из рычагов нижней пары.The saw frame is provided with an additional pair of levers, with both upper pairs of levers being connected to the upper cross member by means of rocker arms, pivotally mounted on its fingers, and each drive rod has an additional arm, to which one of the lower pair arms is connected.

Кроме того, рычаги имеют противове10 сы.In addition, the levers have counterweights.

На фиг, 1 изображен механизм резани , общий втЩд.на фиг. 2 - траектори  движени  смежных зубьев пилы.FIG. 1 shows the cutting mechanism, the general case of FIG. 2 shows the trajectory of movement of adjacent saw teeth.

Механизм резани  содержит пильную рамку 1 с подвеской в виде двух верхних The cutting mechanism contains a saw frame 1 with a suspension in the form of two upper

15 пар 2 и 3 и нижней пары 4 однозвенньл рычагов с противовесами 5 шарнирно прикреп/юнными к станине 6, причем верхние пары 2 и 3 рычагов св заны с 15 pairs 2 and 3 and the lower pair 4 single-lever levers with counterweights 5 are pivotally attached to the frame 6, with the upper pair 2 and 3 of the levers being associated with

20 -верхней поперечиной 7 пильной рамки I коромыслами 8 и 9 через п:альцы 10 и 11 ве{5хней поперечины 7, а шатуны 12 и 13 .кривошипно-шату1шого механиз20 - upper cross member of 7 saw frame I with rocker arms 8 and 9 through n: alts 10 and 11 ve {5 cross bar 7, and connecting rods 12 and 13. Crank-and-pinion mechanism

Claims (2)

Формула изобретенияClaim 1. Механизм резания лесопильной РА-мы, содержащий пильную рамку с подвес- 15 кой, выполненной в вице верхней и нижней пар однозвенных.рычагов, шарнирно прикрепленных с станине, причем верхняя пара рычагов связана с верхней поперечиной -пильной рамки, а нижняя через шатуны кривошипно-шатунного привода пильной рамки - с нижней ее поперечиной, отличающийся тем, что, с целью повышения эффективности процесса пиления, верхняя поперечина снабжена дополнительной порой рычагов, при этом обе верхние пары связаны с верхней поперечиной посредством коромысел, шарнирно-установленных на ее пальцах, а каждый шатун имеет дополнительное плечо, с которым связан один из рычагов нижней пары.1. The cutting mechanism of the sawmill RA-we, containing a saw frame with suspension 15 , made in the vice of the upper and lower pairs of single-link levers pivotally attached to the bed, the upper pair of levers connected to the upper cross-member of the saw frame, and the lower through the connecting rods the crank drive of the saw frame with its lower cross member, characterized in that, in order to increase the efficiency of the sawing process, the upper cross member is provided with an additional pore of levers, while both upper pairs are connected to the upper cross member by short a thought pivotally mounted on her fingers, and each connecting rod has an additional shoulder, with which one of the levers of the lower pair is connected. 2. Механизм по π. 1, отличающий с я тем, что рычаги имеют противовесы.2. The mechanism by π. 1, characterized in that the levers have counterweights.
