Description

The proposed tool for drilling knots in table products and. The manufacture of stoppers for sealing the holes thus obtained is one of the tools of this kind, in which drills are used to make stoppers and perks for drilling holes.

In FIG. 1 depicts the external appearance of the proposed tool; FIG. 2 is a front view with a partial vertical section; FIG. 3rd view from above; FIG. 4 a horizontal section along the line AB in FIG. 2; FIG. 5, 6.9 and 10 perks; FIG. 7 and 11-kind drills. partial vertical section; FIG. 8 and 12 are the top of these drills; FIG. 13-cutting drill elements in expanded form.

The proposed tool consists of a chuck 11 (Fig. 1) in which the perks are fixed and the drills are screwed. The perks have an ordinary design, and the drills 3 (Fig. 7) used in this tool are hollow cylindrical bodies with a thread at one end for screwing in and into the cartridge, and at the other, cutting end they are circumferentially spaced in groups cutters a, b, c (fig. 13), with cutters b having semicircular cutting edges, are separated in different directions and serve as cutters, and cutters c have a wedge-shaped shape and their cutting edges are somewhat elevated in relation to cutters a and b - the cutter’s operation is reduced to stripping the incised a and b h STI wood shavings ejection, skaplivayuscheys in troughs g with bevels d.

The drill rotates in the drilling machine, makes a round thread with its cutters, which deepens as the spindle of the drill machine is pressed, and cuts the board through, and the part of the tree that goes inside the drill and will serve as a stopper, which upon repeated operation is automatically thrown through windows and cartridge.

The combination of a drill and a perk l (figs. 1,2,5, 6) inserted inside it serves to form the corresponding holes. A set of plug drills is designed so that a plug made by a large number of drill 1 (Fig. 1, 2) enters a hole made by a smaller number-drill 2-7 (Fig. 5-7), and the plug made by a drill 2 will enter into the hole of the next smaller drill number 3-8 (fig. 9-11), etc.

The subject of the patent.

A tool for drilling knots in tableware and making stoppers for fixing the holes thus obtained, using a conventional type of cork drill and a conventional perk, characterized by the fact that the cutting elements of a cylindrical drill 3 (Fig. 7) are formed along its periphery to cutting groups a, b, eV (fig. 13), of which the cutters a and b, divorced in different directions, are cutters, and the cutter c serves between the cut parts of the chips placed in the hollows d, which drill 3 one is used to obtain traffic jams With a perk L inserted inside it (Figs. 1, 2, 5, 6) - for the formation of a corresponding hole, the drills are selected in groups so that the cork made by drill 1 (Fig. 1, 2) enters the hole reproduced the next drill bit 2-7 (fig. 5-7), the cork delivered by the drill 2, corresponded to the hole formed by the drill 3-8 which is further along the non-drill number (fig. 9-11), etc.
