Definitions
- the invention relates to a method for producing a bung from a metal barrel, in particular the making of a bung in a barrel with a relatively thin sheet metal wall, typically less than 2 mm thick. It relates to an improvement making it possible to simplify the production of such a drain and to reduce the cost price.
- a known method for producing a plug in a metal barrel in particular a barrel with a thin wall, consists in attaching to the wall of the barrel a collar, prefabricated, relatively thick and internally threaded.
- a collar has a flat base with an octagonal outline.
- the wall of the barrel is drilled and the metal is conformed around the bore by making both an octagonal imprint on the internal side and a cylindrical chimney extending outwards.
- the flange is inserted in the chimney so that its octagonal base takes place in the corresponding cavity, with the interposition of a seal. The fixing of the flange is ensured by a roll of the latter on the edge of said chimney.
- the invention makes it possible to eliminate purely and simply the flange and the seal while simplifying the operations for forming the plug.
- the invention relates to a method for producing a bung of a metal barrel, consisting in particular of shaping a substantially cylindrical chimney by stamping the wall of the barrel, characterized in that it consists in forming a thread inside. from this fireplace.
- a thread tapping for a thin sheet, a thread tapping, known per se, is used, making it possible to obtain the thread without removing any metal. It should be noted that this type of thread tapping is traditionally not possible on thin sheets.
- said chimney is reinforced externally during the production of the threading to avoid any risk of tearing of the sheet.
- the peripheral part of this dish remains at the base of the chimney, which produces a sort of bowl favoring the complete emptying of the barrel, at the end of use. The possible cleaning of the barrel is also greatly facilitated by this arrangement.
- FIG. 1 illustrates the main operations for forming a metal drum plug in accordance with the principle of the invention.
- the drain is here shaped in an end wall 1 1 of the barrel, generally flat or very slightly curved; it could also be made in the cylindrical wall of said barrel.
- a first operation illustrated in Figure 1 is to achieve a slight bulge 12, by deformation of the sheet in the wall 1 1 from the inside to the outside, at the desired location of the plug. An internal bowl is thus defined.
- the second operation illustrated in FIG. 2 consists in shaping a substantially cylindrical chimney 14 by stamping with a puncture in the wall of the barrel, at the location of the bulge.
- FIG. 3 A third operation illustrated in FIG. 3 consists in folding down the projecting edge of the chimney to form an outside roll 16.
- the tools necessary for carrying out the operations illustrated in FIGS. 1 to 3 are conventional and have therefore not been shown.
- FIG. 4 illustrates a step more particularly representative of the method of the invention. This step takes place after the roll 16 has been formed.
- FIG. 4 shows the wheel tap 18 before the threading operation.
- the chimney is surrounded by a rigid ring 20, consisting of at least two annular sectors, during the production of the thread.
- This ring or any similar structure defines a cylindrical annular abutment surface which comes to bear against the external face of the chimney 14.
- the sectors of the ring define an external frustoconical bearing 22.
- An external, annular, monobloc support, comprising a bearing complementary frustoconical (not shown) bears against this frustoconical bearing 22 to keep the sectors in place during the tapping operation.
- FIG. 5 illustrates the withdrawal of the sectors constituting the rigid ring 20, once the thread 26 has been formed in the wall of the chimney 14.
