Abstract

The utility model discloses a patterned pipe, which comprises a carbon steel core and a copper layer. The copper layer is sleeved on the outer lateral face of the carbon steel core to be combined into a base in a matched manner, the base is machined so that patterns appear on the outer lateral face of the copper layer by means of cold rolling in a concave manner, and thereby the inner lateral face of the copper layer projects to form projections to be embedded onto the outer lateral face of the carbon steel core. The carbon steel core and the copper layer are laminated by means of cold rolling, and thereby elegant, vivid, delicate and beautiful patterns can be machined on profiles.

Description

A kind of pattern pipe

Technical field

The utility model relates to a kind of section bar, especially relates to a kind of pattern pipe.

Background technique

Existing section bar as tubing such as indoor and outdoor guardrail, ladder access guardrail, green belt guardrail or window guardrails, adopts the carbon element steel or stainless steel to be made mostly.Employing carbon steel is made, need carry out anti-corrosion treatment to the carbon steel surface, anti-corrosion treatment generally includes several methods such as paint spraying, plastic-blasting, spray zinc, aluminium-plated, aluminium-plated magnesium alloy or spray allumen, and these methods have following shortcoming: one, easily rust easily produces rust staining; Its two, not environmental protection; Its three, moulding is simple, can't process decorative pattern, poor effect can't reach long-term corrosion protection protection purpose.The employing stainless steel is made, though not perishable, also have following shortcoming: one, cost height; Its two, the noble metal use amount is big; Its three, moulding is single.

The model utility content

The utility model provides a kind of pattern pipe, and it has overcome the existing existing deficiency of section bar in the background technique.

The technological scheme that is adopted that the utility model solves its technical problem is:

A kind of pattern pipe, it comprises a carbon steel core body and a bronze medal layer, described copper layer is adaptive to be set in outside the carbon steel core body side and group is matrix, described matrix is by cold rolling rolling finishing, the side is concaved with floral designs outside the described copper layer, the side is protruding with projection within the described copper layer, described projection interlocking side outside the carbon steel core body.

Among one preferred embodiment: the side is set to concaveconvex structure outside the described carbon steel core body.

Among one preferred embodiment: the concaveconvex structure of described carbon steel core body is a waveform.

Among one preferred embodiment: the concaveconvex structure of described carbon steel core body is the square profile of tooth.

Among one preferred embodiment: described carbon steel core body is hollow body.

Among one preferred embodiment: described carbon steel core body is solid body.

The technical program is compared with background technique, adopt laminated carbon steel core body of cold rolling rolling finishing mode and copper layer, therefore it has overcome the existing deficiency of background technique, and has a following advantage: 1, can on section bar, process fineness, floral designs clear, exquisite, attractive in appearance, 2, can within the copper layer, generate projection in the side simultaneously, 3, projection can be rabbeted at the carbon steel core body, utilize laminated the fixing between projection interlocking realization carbon steel core body and the copper layer; 4, can reduce, avoid ambient air to enter between copper layer and the carbon steel core body, reduce, avoid dioxygen oxidation carbon steel core body, reduce, avoid the carbon steel core body to get rusty, corrode.

Because concaveconvex structure is arranged in the side outside the carbon steel core body, so the projection that generates when cold rolling roll extrusion of copper layer be easy to rabbet the outer side surface at the carbon steel core body, can guarantee the protruding outer side surface that can rabbet at the carbon steel core body.

Embodiment

First preferred embodiment

Please refer to 1 to Fig. 6, a kind of pattern pipe, it comprises a carbon steel core body 10 and a bronze medal layer 20.Described carbon steel core body 10 and copper layer 20 are suitable, for example are Spielpassung, so that socket assembling, certain not as limit, other also can be suitable for as crossing the cooperation of overflowing.

Among the present embodiment, be preferably in that the side is set to concaveconvex structure 11 outside the described carbon steel core body 10, described concaveconvex structure 11 for example is waveform, zigzag fashion, square profile of tooth, spirality (as establishing inclined groove, the inclined groove of the adjacent side of section bar is connected) etc.

Described copper layer 20 is adaptive to be set in outside the carbon steel core body 10 side and group is matrix, described matrix by cold rolling rolling finishing so that the side is arranged with out floral designs 21 outside the described copper layer 20, so that the side protrusion forms projection 22 within the described copper layer 20, so that described protruding 22 interlocking sides outside carbon steel core body 10.

Among the present embodiment, described cold rolling roller machine can adopt existing cold rolling roller, and it generally comprises two rolls, is arranged with mould on the described roll, convexes with the projection suitable with floral designs on the described mould.Add man-hour, described base material is by two rolls, and the mould action of two rolls makes that the side is arranged with out floral designs 21 outside the described copper layer 20 on base material, making that protrude the side within the described copper layer 20 forms projection 22, makes described protruding 22 interlocking sides outside carbon steel core body 10.
