Abstract

The invention relates to woodworking machinery. The purpose of the invention is to reduce the metal intensity of the machine. The machine comprises a bed, a feed mechanism, milling calipers with tables equipped with guide lines and basing knives. The working edges of the 15 knives are installed in the machining plane at an angle of 2-8 to the feed direction, and the top of the angle is directed toward the feed. The working edges 15 of the blades are made with sinuses 18, on the side surfaces of which they form additional working edges 19. The total height of the remaining sections of the working edge is 1 / 2-1 / 3 the height of the knives above the surface of the machine. Additional working edges are located at an angle of 60-90 °. to the working edge of the knife. When processing lumber 20, in addition to the spin forces appearing on the working edges 15, pulling forces appear on the additional working edges 19, which reduces the overall pressing force of the lumber. 5 il. tjD About c

FIG. five

The invention relates to wood processing equipment and can be used in wood processing industry.

The purpose of the invention is to reduce the metal capacity of the machine by decreasing it (spin extraction.

FIG. 1 shows the proposed machine, top view; in FIG. 2 — the A-A phases in FIG. one; in fig. 3 - view B and FIG. 2; Fig. 4 is a notch pattern; in fig. 5 device | 5th knife

Milling and edging machine vk: shakes: tannin 1, feed mechanism 2 with facing rollers 3 and 4, milling supports 5 and 6 with working parts - cutters 7 and 8 and supporting tables 9 and lOj equipped with guide rails tH rulers 1 1 and 12 and 11: 14 and 14. The base knives 13 and protrude above the supporting posts 9 and 10, the working edges 15 of the knives J13 and 14 are installed in the planes of the 16 and 17 planes at an angle of 2-8 ° to the feed direction, the vertex head sent to meet the pitch.

The working edges 15 of the bases 13 and 14 are made with the sinuses 8, 3. whose side surfaces form additional working edges 19,

i The total height h, o..h of the remaining sections of the working edge 15 is 1 / 2-1 / 3 the height of the knives 13 and 14 above the twelve tables 9 and 10,: Additional working edges 19: angled 60 -90 to work- Whose-edge knives 13 and 14, 20 - sawn material.

The machine works as follows

Timber 20s, for example, a two-punch 1-bar, serves myka 2 feeds to the base knives 13 and 14,

The base knives 13 and 14 cut into the lower face of the sawn timber 20; the obstacle thereby to its transverse per bazirobash; o, an incision in the lumber begins to form working edges 15. In this case, at each section of the working edge, a cutting force Yi arises; vertical component

where Fg {is part of the circumference (lumber pressing force RD-). Further, an additional working edge 19 is cut into the wood, which is a cutter for seamless cutting, which deepens a cut in the lumber. At this additional edge there is a cutting force F, the vertical component of which FJ is a part of the total force FJ of pulling in the material, i.e. a part of the pressing force is compensated by the force of pulling.

Upon further movement of the sawn timber, the cutters 7 and 8 process the edges of the sawn timber, and thanks to the cuts made by the knives 13 and 14 on the bottom of the wood, chipping at the tool exit from the cutting zone is eliminated. The finished sawing blade enters between the rulers 1 and 12, which stabilize the movement of the material when it leaves the knives 13 and 14.

The use of the proposed milling and trimming machine allows to reduce the metal intensity of the machine by reducing the pressing forces of lumber.

Claims (1)

Invention Formula A milling edger, including a frame, a feed mechanism, milling calipers with supporting tables, equipped with guide lines and knife basing (-1i, protruding above the table surface, the working edges of which are installed in the working plane at an angle of 2-8 ° to the direction feed, and the vertex of the angle is directed towards the feed, which is due to the fact that, in order to reduce the metal intensity of the machine by reducing spin forces, the working edges of the clamping knives are filled with sinuses, on the side surfaces of which additional working edge, wherein the total height ostavschihs working edge portions is 1 / 2-1 / 3 the height of the blades above the table surface, and additional Started Chie edge 60-90 located at an angle to the leading edge of the knife. 1 a-a Thebes.2 Phie.
