The invention relates to the woodworking industry, namely, machines for the production of rods special profile and purpose. The goal is to increase productivity and simplify the design of the machine. The essence of the invention lies in the fact that in a machine containing a support frame (C) 2, cutting tools, a billet feed mechanism of the workpiece with a movable carriage (PC) 19 and a pusher, a cassette 8, guides and drives, C 2 are made vertical and stationary. The side chamfering tools are made in the form of a pair of identical centering profile cutting heads (WG) 23, which center the workpiece both during processing and during transportation. WG 23 is installed between the intermediate guide (MO) 6 and the working guide (PH) 7 and is suspended on spring-loaded levers 27 fixed to PN 6. Cutting tools for applying the upper and lower marks processed after side chamfers are made in the form of a pair of cutters 33, fixed on C 2 and rotating from the drive, while the axis of their rotation is moved perpendicular to the longitudinal axis of the treatment zone. Cutting cutter 35 for cutting through the center 3 is fixed in the movable body of the lever 38, having a finger 39, interacting with the shaped lag 40 of the drive disk 41, fixed on C 2 and rotating from the drive. When this cutter 35 is made with the possibility of lifting and lowering in a cyclic mode in accordance with the processing technology of the workpiece. The rocker feed mechanism is made in the form of a movable carriage PC 19 with a cylindrical support 18 inside and a protrusion on which is mounted a centering grip pusher fed from cassette 8 and moved to its initial position for processing side chamfers WG 23. PC 19 moves along C-shaped guides 5, which are attached to the ends of the C 2 through the covering brackets 20, which provides not only the rigidity of the structure, but also the accuracy of the feed of the workpiece. C-shaped guide 20, PN 6 and PH 7 are installed in series with each other and are spaced apart with a certain gap between them. PN 6 is made in the form of a trough-shaped tray with end stops for fixing the cassette 8. The PH 7 is equipped at the top and bottom with through windows of appropriate shape for cutters 33, 35 and a movable profile roller 36 with a wedge-shaped groove, as well as for pulling rollers 52. A distinctive feature of the machine is the original design of the WG 23 centering profile cutting heads, each of which contains a base, a cover and a profile cutter placed between them, mounted in a shaped groove of the base and cover, the cross section of which corresponds to cheniyu cutter. These relationships provide high performance, simplicity and ease of use. 3 hp f-ly, 17 ill.
