Abstract
The utility model discloses a metal composite rod material technology which is composed of a metal sleeve and a metal rod core. The internal diameter of the metal sleeve is slightly larger than the external diameter of the metal rod core, and the metal rod core is inserted into the metal sleeve; the metal sleeve arranged outside and the metal rod core arranged in the middle can be tightly integrated into a gapless and weldless metal composite rod structure through the hard matching between an external mold and the draw-in process. The utility model has the advantages of reasonable structure, good quality of rod, and long service life; moreover, various welding and curving processes can be proceeded, and the metal rod core can be externally covered with various metal tubular products as required, such as copper tubes, brass tubes, bronze tubes, titanium alloy tubes, stainless steel tubes, alloy tubes, etc., so that the utility model is not only an ideal substitute to anti-theft doors, anti-theft windows, guard rails and staircase posts, but also a new industrial product.
Description
Affiliated technical field
The utility model relates to the metal composite processing technique field, the no gap solid bar that specifically a kind of metal bar core that the metal sleeve of outside is middle with being arranged on sleeve pipe is combined into one.
Background technology
At present, be widely used in metal materials such as antitheft door, burglary-resisting window, guardrail and stair column, most of carbon steel bar or stainless steel pipe of adopting.Along with improving constantly of the building and the standard of decoration, the tubing of these single metals or bar can not adapt to actual needs far away.Such as, though its appearance better appearance of stainless steel pipe, because its centre is hollow shape, thus be not easy to bending process, and intensity is also not enough.Carbon steel bar commonly used though certain intensity is arranged, gets rusty easily, and once paints every 1～2 year needs center of gravity brush.In order to address the above problem, Chinese patent CN2485066Y has proposed " the compound bar of a kind of carbon steel core stainless steel ", and pressing one deck stainless steel substrates promptly curls in the outside of carbon steel plug.The compound bar of this stainless steel is compared with single carbon steel bar or stainless steel pipe, and good looking appearance is corrosion-resistant, and has rigidity intensity preferably.But, because what be provided with in the outside of carbon steel core is one deck stainless steel substrates, by the composite bar that just constitutes after curl pressing and the welding.Therefore, the composite bar of this structure, its major defect are that the surface has weld seam, between the carbon steel plug of the stainless steel substrates of outside and centre certain clearance are arranged.This structural deficiency makes between surperficial weld seam and carbon steel core and the stainless steel substrates and produces oxidation and rusting, influences quality, reduction of service life.
Summary of the invention
In order to overcome the deficiency that existing metal composite rod structurally exists, it is a kind of easy to process that the utility model provides, and production cost is low, the no weld seam that specious and rigidity intensity is good, no gap metal composite bar.
The technical scheme that its technical problem that solves the utility model adopts is: this metal composite bar, constitute by metal sleeve and metal bar core, the internal diameter of described metal sleeve is slightly larger than the external diameter of metal bar core, the metal bar core inserts in the metal sleeve, hard cooperation by external mold and pulling-down, the metal sleeve and the middle metal bar core of outside closely are combined into one, form no gap, weldless metal composite bar structure; Between the internal diameter of metal sleeve and the metal bar core external diameter, compound preceding gap is 0.2～0.6mm.
As required, metal sleeve can be selected circle, square pipe for use, selects corresponding circle, square metal rod core simultaneously for use, makes the metal composite bar of shapes such as cylindrical, square tube shape.
The utility model major advantage compared with prior art is rational in infrastructure, and the bar quality is good.Owing to the metal bar core inserted in the metal sleeve and the hard cooperation by external mold and pulling-down, both closely is pressed into one.So there is not the gap between metal bar core and the metal tube, the no weld seam in surface, the rigidity intensity of bar is good, long service life, and can carry out the curved processing of various welderings.Next is according to various purposes, can coat various metal pipe materials in the outside of metal bar core.As copper tube, brass tube, bronze tube, Ti-gold tube, stainless steel tube and compo pipe etc., be antitheft door, burglary-resisting window, guardrail and the desirable substitute products of stair column, also be industrial new product.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is a structural representation of the present utility model.
1. metal bar core, 2. metal sleeves among the figure.
The specific embodiment
As shown in Figure 1, this metal composite bar, diameter are 12mm, and it is made of circular stainless steel metal sleeve pipe 2 and circular carbon steel metal rod core 1.The diameter of metal sleeve 2 is 12.4mm, and pipe thickness is 0.3mm, and its internal diameter is 11.8mm.The diameter of metal bar core 1 is 11.4mm, and between metal sleeve 2 internal diameters and metal bar core 1 external diameter, compound preceding gap is 0.2mm.The metal bar core 1 of shaping alignment is inserted in the metal sleeve 2 of shaping alignment,, the metal sleeve 2 of outside and the metal bar core 1 of centre closely are combined into one, form no gap, weldless metal composite bar structure by the hard cooperation of external mold and pulling-down.
Claims (2)
1, a kind of metal composite bar, comprise metal sleeve (2) and metal bar core (1), it is characterized in that: the internal diameter of described metal sleeve (2) is slightly larger than the external diameter of metal bar core (1), metal bar core (1) inserts in the metal sleeve (2), hard cooperation by external mold and pulling-down, the metal sleeve (2) and the middle metal bar core (1) of outside closely are combined into one, form no gap, weldless metal composite bar structure.
2, a kind of metal composite bar according to claim 1 is characterized in that between the internal diameter and metal bar core (1) external diameter of metal sleeve (2), and compound preceding gap is 0.2～0.6mm.
