Abstract
A bimetal wear-resistant elbow relates to a production process of a metal part, in particular to the technical field of the structure of the elbow of a material conveying system in the industries of nonferrous metal, black metal, steel, smelting, metallurgy, mine, electric power, building materials and the like. And sleeving a steel pipe outside the metal bent pipe main body, and welding pipe joints at two ends of the steel pipe through flange rings respectively. Because the utility model discloses having the high rigidity and better wearability of metal return bend main part, simultaneously, still having the weldability of steel pipe, accomplishing both to have, simple to operate is swift saves time, in addition, because the product wholeness can be good, long service life, the maintenance volume is few, has practiced thrift raw and other materials, makes the user show and has reduced intensity of labour and manufacturing cost, has realized energy-efficient environment-friendly production.
Description
Technical field
The utility model relates to a kind of production technology of metal parts, particularly is applied to the technical field of structures of the bend pipe of industry material-transporting systems such as coloured, black, iron and steel, smelting, metallurgy, mine, electric power and building materials.
Background technique
The abrasion-proof bent tube (or elbow) that industry material-transporting systems such as just coloured at present, black, iron and steel, smelting, metallurgy, mine, electric power and building materials adopt, according to user's use condition reflection for many years and expert investigation result of study show in the industry, abrasion-proof bent tube (elbow) uses, all the time be subjected to a puzzlement that is difficult to put the axe in the helve, exactly if will improve the product weldability, product hardness HRC＜30, but product wear-resisting property difference is not wear-resisting, and working life is short; If will improve the product wear resistance, product hardness HRC＞35, but the product weldability is poor, easily broken, crisp, split; Therefore can not accomplish that both get both.
The abrasion-proof bent tube (elbow) that existing material-transporting system adopts has three kinds, and first kind is alloyed steel and other abrasion-proof bent tube; Second kind is the cast stone abrasion-proof bent tube; The third is ceramic-lined composite abrasion-proof elbow.Three kinds of abrasion-proof bent tubes are all to adopt between welding and the material-transporting system equipment metalwork to realize being connected.Defective is: (1) alloyed steel and other abrasion-proof bent tube abrasion-resistance are poor, generally to increase the thickness of outer arc, prolong wearing-in period, can not fundamentally solve the problem of quick abrasion, and welding performance is poor, needs on-the-spot butt welded seam heat treatment, brings sizable difficulty for on-the-spot installation and maintenance.(2) cast stone abrasion-proof bent tube interlayer is thick, and wear surface knapsack wall thickness has 25～40 millimeters, thick heaviness, and the consumptive material feed consumption, fragmentation easy to crack, and often there is pore inside, easily stays hidden danger, not energy-conserving and environment-protective, in case worn out, the scene can't be repaired.(3) ceramic-lined composite abrasion-proof elbow microfissure is many, and matter is crisp frangible, and local shedding lost efficacy easily, and shock resistance is poor.(4) lack working life, the installing/dismounting maintenance is very inconvenient, has strengthened amount of maintenance, labor strength and cost of production.
The model utility content
The utility model purpose is to design a kind of hardness height, excellent wear resistance, duplex-metal abrasion-proof bent tube that weldability is strong.
The utility model comprises the metal winding pipe main body, is nested with steel pipe outside the metal winding pipe main body, at the two ends of described steel pipe respectively by flange circle welded stub connection.
Owing to the utlity model has the high hardness of metal winding pipe main body and wear resistance preferably, simultaneously, also had the weldability of steel pipe, accomplished that both get both, quick and easy for installation saving time, in addition, because the product overall performance is good, long service life, amount of maintenance is few, save raw material, made the user significantly reduce labor intensity and cost of production, realized highly effective energy-conserving environmental-protecting type production.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, steel pipe 2 is outer to be enclosed within outside the metal winding pipe main body 1, and the gap must not be greater than 2～4mm, and makes the two ends of steel pipe 2 slightly grow metal winding pipe main body 1.
The welded flange circle 3 respectively at the two ends of steel pipe 2 is nested with pipe joint 4 at the interior circle of flange circle 3, and the inner of pipe joint 4 is contacted with metal winding pipe main body 1, and is last, and pipe joint 4 and 3 welding of flange circle are fixed.
Claims (1)
1, duplex-metal abrasion-proof bent tube comprises the metal winding pipe main body, it is characterized in that outside the metal winding pipe main body, being nested with steel pipe, at the two ends of described steel pipe respectively by flange circle welded stub connection.
