Abstract
The present invention relates to a method for socket jointing a metal pipe and a wooden piece. An inserting end of a wooden piece is inserted into a metal pipe, and a hob is used for rolling on the surface of the metal pipe along a radial direction in a rolling mode, so a ring-shaped impression or a spiral impression is formed on the metal pipe for fixing the wooden piece in the metal pipe. The present invention has the advantages of stable structure and beautiful and harmonious appearance.
Description
The invention belongs to metal tube furnature construction technical field.
Existing metal tube furniture, the general metal tube structure that adopts, even idol has ligneous piece to occur, also just rely on screw or bonding being fixed in the structure, structure technology development along with metal tube furniture, a kind of noble quality, elegance of both having paid attention to plastic arts has the Piao of returning again and returns very, and the furnature construction that goes back to nature obtains exploitation.Promptly, on the metal tube structure, be inserted in a section ligneous piece that has natural wood veins in the middle of metal tube, because the Metal furniture steadiness that requires structurally, with harmony attractive in appearance, this has proposed the corresponding techniques requirement with regard to the connecting means of giving ligneous piece and metal tube.
Purpose of the present invention in order to solve ligneous piece and metal tube in being connected manufacturing process, had both required its structure to have steadiness just, can satisfy it again and have harmony attractive in appearance and a kind of metal tube that proposes and the new method of ligneous piece's socket.
The objective of the invention is to realize by following technical solution:
The insertion section that cooperates with metal tube of ligneous piece termination is made the size that its diameter equals hole dimension in the metal tube, insert in the metal tube then, adopt the mode of roll extrusion that radially roll extrusion is carried out on the metal tube surface that the roll extrusion cutter head withstands outside the insertion section again, the part produces radial compression after making the metal tube pressurized, ligneous piece is fastened in the metal tube, the cutter head of roll extrusion both can be perpendicular to the rotation of metal tube shaft axis and exert pressure, make metal tube boil down to one closed ring, also can be to exert pressure along the rotation of metal tube shaft axis spiral, making the metal tube impression is a helical, for ease of roll extrusion, can insert on the section in ligneous piece and process impression in advance.
Further set forth the utility model content below in conjunction with Figure of description and embodiment:
Fig. 1 is closed ring impression processing schematic representation;
Fig. 2 helical impression processing schematic representation.
Ligneous piece 2 makes and the identical cylinder of metal tube 1 outside dimension usually, and it inserts section 3 and makes the size that certain tolerance is arranged with metal tube 1 internal diameter.If size is big slightly, executing certain pressure slightly is inserted into the insertion section 3 of ligneous piece 2 in the endoporus of metal tube 1, then, color roller is aimed at the radial surface that inserts the outer metal tube of section with the roll extrusion cutter head and is carried out roll extrusion, through one week of roll extrusion, make impression become a close ring (see figure 1) on perpendicular to the metal tube shaft axis.Thereby ligneous piece is fastened on the metal tube.For ease of roll extrusion and enhancing tightness, can insert on the section in ligneous piece and process impression in advance.Rotary knife cutter on the also available cutting metal pipe of roller, the impression processing cutter that only needs cutter head to be changed into blunt mouth gets final product.Closed impression can be processed a ring, and two rings or more are mainly looked and inserted segment length, non-some the impression rings of the corresponding cooperation of mold pressing decorative pattern that insert section of also visual metal tube.
Processing helical impression only needs the movement locus of roll extrusion cutter head is designed to make corkscrew motion along the metal tube shaft axis on the metal tube surface, and the impression of processing just is the helical (see figure 2).
The present invention has overcome ligneous piece and metal duct ligation compared with prior art Close and adopt screw to connect or bonding defective, it is more firm to have a connection, outward appearance The obvious advantage of coordination more attractive in appearance.
Claims (3)
1, metal tube and ligneous piece's socketing method, relate to Metal furniture structure fabrication technology, it is characterized in that: the termination of ligneous piece (2) is provided with the insertion section (3) that one section diameter equals the interior hole dimension of metal tube (1) and matches with metal tube, after inserting section (3) insertion metal tube (1) endoporus, adopt roll squeezing type that roll extrusion cutter head (4) is withstood the metal tube appearance of inserting section and carry out radially roll extrusion, make the local radial contraction that produces of metal tube pressurized, ligneous piece is fastened in the metal tube.
2, method according to claim 1, it is characterized in that: roll extrusion cutter head (4) both can revolve axle perpendicular to metal tube (1) shaft axis exerts pressure, making the metal tube impression is a closed ring, also can be to exert pressure along the rotation of metal tube shaft axis spiral, and making the metal tube impression is a helical.
3, method according to claim 1 and 2 is characterized in that: can process impression in advance before inserting metal tube on ligneous piece's insertion section.
