Description

(54) CUTTING SUPPORT

one

The invention relates to shelling machines for the production of peeled veneer and can be used in the woodworking industry.

Known caliper shelling machine, including a knife holder with a shelling knife, traverse clamping line and undercutting knives, sliders and mechanisms of rotation of the knife holder and traverse clamping ruler 1.

Also known is a caliper of a shelling machine, including a knife holder, undercutting knives, traverse of the clamping ruler, sliders, mechanisms for changing the position of the clamping ruler, and a mechanism for automatically changing the cutting angle 2.

A disadvantage of the known supports is the impossibility of obtaining peeled veneer from low-grade raw materials with weakened wood in the central zone of the churaki.

The purpose of the invention is to expand the technological capabilities of the machine by producing peeled veneer from raw materials with a weakened central zone.

This goal is achieved by the fact that the knife holder is made with grooves perpendicular to the axis of the spindle, and the trimming knives are installed in the knife holder grooves with the possibility of adjusting their position with the help of locking elements.

, 0 The machine caliper includes a knife holder 1 with a shelling knife 2, traverse 3 of the pressure bar 4, sliders 5, a device for changing the degree of crimping of the veneer during cutting, consisting of a worm gear 6 and an eccentric shaft 7 traverse 3 of the pressure bar (when rotating worm gear the pair is provided with the inclination of the traverse of the pressure bar and the change of the distance between the pressure bar 4 and the shelling knife 2); presser lift mechanism 8

20 rulers; a cutting angle change mechanism consisting of a shaft 9, a worm gear pair 10 and an eccentric shaft 11 of the blade holder 1. The slide rails move along inclined guides of the machine 12, the position of which is changed by means of a set screw 13 which ensures automatic change of the cutting angle with decreasing diameter razlushivaemoy churaka due to the rotation of the knife holder in the vertical plane relative to the blade shelling knife during the forward movement of the caliper. The front wall of the knife holder I, on the KOTOpolw, the shelling knife 2 is attached, displaced by the value a to the axis of rotation of the spindles of the machine 0-0; this offset determines the depth of penetration of the knife into the separable churak. The side surfaces of the blade holder 1 are grooves 14, in which undercutting knives 15 are installed, which are secured in the required position by a locking bolt 16 and a spring lock 17, which are inserted into special slots 18 selected in the front wall of the knife holder 1., Shelling machine support works as follows. After turning the chorack into rotation from the shafts, the caliper moves along track screws (not shown) in the direction of the rotation center of the chorak at feed rate I. When approaching the choraka, the undercutting knives 15 start cutting the wood fibers, forming a groove in the chocker along the ends of the shelling knife 2 depth equal to the size of the advance installation of pruning knives. This creates conditions for the smooth introduction of the holder with shelling
