Description

The invention relates to woodworking equipment and can be used in the woodworking industry.

A woodworking aggregate machine is known, including a frame, cutting, cutting and feeding mechanisms [1].

Also known aggregate machine for the manufacture of sawn timber, including a frame, a cutting mechanism in the form of band dust, the mechanisms of transverse and longitudinal incisions in the form of blocks of round saws, feed mechanism, remote conveyors and drives (2] ·

The disadvantages of the known machines are large intensity and increased size. '

The purpose of the invention is to reduce the metal capacity and size.

The goal is achieved by the fact that in a machine tool that includes a frame, a cutting mechanism in the form of a band saw, cross-cutting and longitudinal notching mechanisms in the form of blocks of circular saws, the feed mechanism, outboard conveyors and drives, the cutting mechanism is located between the cross-cutting and longitudinal notching mechanisms, and the band saw is equipped with teeth on both edges, the feed mechanism is made in the form of a caliper with clamping units, vertical movement and reciprocating movement in a direction perpendicular to the cutting edges of the ribbon pi ly.

FIG. 1 schematically shows the proposed machine, side view, in FIG. 2 is the same, top view, in FIG. 3 - section A-A. in fig. one .

An aggregate machine for making sawing products includes a frame 1, a cutting mechanism 2 in the form of a band saw 3, in which the teeth are made on both edges, a transverse incision mechanism 4 in the form of a block of circular saws 5, a longitudinal incision mechanism 6, also made in the form of a round block 7 saws, feed mechanism 8, outboard conveyors 9 and 10 and drives 11 and 12. Cutting mechanism 2 is located between cross-cutting mechanisms 4 and longitudinal 6 notching. The feed mechanism 8 is made in the form of a slide 13 with a beam 14 on which a clamping unit is installed, comprising a gripper 15 s.

the hydraulic cylinder 16, the node of the vertical movement, including the rails 17 and the toothed sectors 18, pivotally mounted in the brackets 19.

5 The latter are fixed on beam 14. · The gear sectors 18 are connected to the hydraulic cylinder 20. The support 13 is also provided with a reciprocating unit in the direction,

10 perpendicular to the cutting edges of the band saw, containing guides 21, sleeves 22 and hydraulic cylinder 23. The block of circular saws 5 has a mechanism 24 for adjusting it to a height of 6 in height.

15 pair of screw-nut. The block of circular saws 7 is mounted on a carriage 25 with rollers 26, equipped with a longitudinal movement drive 27 and a height adjustment mechanism 28 in the form of a screw-nut * 20 pair. . The machine is also supplied with a feeder 29,

The machine works as follows. Before starting, circular saws 5 are fixed to each other at a distance equal to the length of the planted planks, and the mechanism 24 is installed in height so that the cut in the workpiece is somewhat deeper than two thicknesses of planted plank.

30 Saws 7 are fixed to each other on

a distance equal to the width of the sawed boards, and the height is set by the mechanism 28 so that the depth of the cut in the workpiece is not much more than two thicknesses of the sawed boards. The feeder 29 serves the next billet 30 in the area of the mechanism 8 feed. The hydraulic cylinder 16 is turned on, which, by gripping the 15, holds the workpiece 30 in the caliper 13.

Further include a hydraulic cylinder 23, moving the caliper 13 to the block of circular saws 5, which cuts the workpiece to a depth of two thicknesses of 45 planks. Next, the workpiece passes over the band saw 3 and stops above the block of circular saws 7. The hydraulic cylinder 20 rotates the sectors 18, which roll over the rails 50 17, lower the beam 14 together with the workpiece 30 by an amount equal to two thickness of the plates. The drive 27 is turned on, moving the cart 25 with the block of circular saws 7, which produce a longitudinal notching of the workpiece. Then the hydraulic cylinder 23 moves the caliper 13 in the opposite direction - from the workpiece 30 passing

longitudinal incisions produce

production of sawn timber tare boards.

The proposed aggregate machine allows you to reduce the size and metal capacity of equipment for sawing a container plank.
