Abstract
The utility model provides a cored electrode with a composite structure, which adopts welded metal pipes or seamless metal pipes for manufacturing wear resistant build-up welding cored electrodes with composite structures. The utility model is characterized in that a metal pipe or a seamless metal pipe is adopted as a welding pipe (1); an electrode coating is coated on the outer side of the pipe; pulverous or granular alloy medicine cores (3) are filled in the pipe; the front end of the cored electrode is screwed and pressed into an arc-shaped sealing (2) and is provided with an arc striking tip (4); the terminal end of the cored electrode is provided with a receiving head (5) and a clamping part (6). The utility model has the advantages that because the welding pipe or a seamless pipe is used for replacing an original folding pipe and the spinning forming of a pipe end replaces a cylindrical sealing head, large quantity of investment for production devices can be saved; production cost is greatly reduced; the sealing of the medicine core is good; powders can not leak and moisture can not be absorbed; metals are uniformly distributed on each of sections along the length direction of the welding electrode; the shape of the utility model is designed with smoothness, beautiful appearance and practicality; the stable combustion of electric arc and the uniformity of deposited metal components and deposited metal organization can be fully ensured.
Description
The utility model proposes and adopt weld metal pipe or seamless metal pipe manufacturer composite construction hardfacing flux-cored electrode.This novel wear resistant built-up welding flux-cored electrode, mine, dig up mine, quarry, dredge, in the engineering such as building, railway, power plant construction, in industries such as building materials, chemical industry, oil, metallurgy, transportation, purposes is very extensive.
The hardfacing flux-cored electrode of the up-to-date production of Britain " Vldaplate " company is put on display in Essen, Germany welding exhibition in recent years.This welding rod is to load powdery medicine core by folding steel pipe, and the tubular end socket is formed on the terminal suit.On the terminal tubular end socket retained part is arranged, the welding rod outside is coated with the skim coating.
The tubulose flux-cored electrode is because diameter is big and the conduction of medicine core, thermal conductivity is very low, therefore electric arc only concentrates on pipe end and burns in the form of a ring, has that welding current is little, the heat input is low, distortion is little, not burning of metal, dilution rate are low, cover characteristics such as efficient and welding productivity height.The tubulose flux-cored electrode of " VIdaplate " company adopts the tubular structure that folds steel pipe and suit, has following several problem: 1, the sealing of powdery medicine core is bad, leaks the powder and the moisture absorption easily.2, the Metal Distribution inequality of steel pipe folded part produces harmful effect to the smooth combustion of electric arc and composition, the structural homogenity of deposite metal.3, the investment of the manufacturing cost height of tubular end socket, folding pipe production line is big.4, in order to improve the covering efficient of deposited metal, increase core diameter and the built-up welding requirement of satisfying special material, simply folding tubular structure flux-cored electrode can not adapt to requirement.
The utility model is achieved in that adopting a kind of metal tube or seamless metal pipe is welded tube 1, pipe is outer to scribble coating, is filled with powdery or granular alloy medicine core 3 in the pipe, and the front end of welding rod is spun into and circular-arcly seals 2, and there are striking tip 4, its end to have to receive 5 and retained part 6.
In the middle of described alloy medicine core 3, wire 8 is housed.
In the middle of described alloy medicine core 3, small diameter metal tube whose 9 can be housed, metal dust 7 is housed in the metal tube 9.
Described alloy medicine core 3 is that the adhesive substance may by powdery alloy and 1%～10% mixes.
The welding rod external form is round or oblate type.
Further specify below in conjunction with accompanying drawing:

Fig. 2, major diameter flux-cored electrode end structure figure
Fig. 3, (a, b) oblate type flux-cored electrode structure chart
Fig. 4, (a, b) silk type composite construction flux-cored electrode structure chart
Fig. 5, (a, b) cast composite construction flux-cored electrode structure chart
See Fig. 1, the utility model adopts commercially available mild steel or other metal minor diameters, and ((thick 0.4～1.2mm) welded pipe or seamless pipe are made flux-cored electrode to 4～20mm) thin-walleds.The welding rod front end directly is spun into steel pipe and circular-arcly seals 2, and processes striking tip 4.The terminal steel pipe spinning of welding rod receives 5, or spinning to receive the prolongation that is pressed into bar-shaped end socket 6 behind the head be the retained part 6 of welding rod.
See Fig. 2, the utility model also can adopt large diameter thin wall pipe flux-cored electrode, its end in pipe, pack into be fit to the end socket that retained part is arranged 6 of caliber after, spinning receives 4 again.
On the basis of welded pipe or the round flux-cored electrode of seamless pipe, the utility model proposes and adopt oblate type flux-cored electrode, see Fig. 3, round flux-cored electrode just can be made oblate type welding rod through flattening or draw down, can make powdery medicine core fine and close more simultaneously.
All belong to the two-layer composite flux-cored electrode among described Fig. 4 and Fig. 5, Fig. 4 is the silk type, and Fig. 5 is a cast, and wire 8 diameters in the general medicine core are 1.0～6.0mm, can be mild steel weldinmg rod or other alloy welding wires 8; Metal tube 9 diameters in the medicine core are 4.0～10.0m, mainly are thin-wall low carbon steel pipe or other metal tubes, interior dress specific alloy powder or other materials.Silk or pipe adopt the suit crimping with the connection of end socket and retained part 5.
The utility model has the advantages that:, manufacture with the mould pressing replacement tubular end socket of pipe end owing to adopt welded pipe or seamless pipe to replace original folded tube.So can save investment of production equipment in a large number, reduce production costs significantly, medicine core good seal, do not leak powder, nonhygroscopic, even along the Metal Distribution on each section of welding rod length direction, the configuration design slyness, attractive in appearance, be suitable for, fully guarantee the uniformity of the smooth combustion of electric arc and deposited metal composition, tissue.When using oblate type flux-cored electrode to implement the built-up welding operation, the built-up welding of the image-tape utmost point is the same, can improve the covering efficient of deposited metal effectively.Composite construction medicine core bar allows to increase core diameter, and arc shape and temperature field are distributed with regulating action, can control mother metal fusion penetration and alloy packing ratio effectively, to satisfy the built-up welding requirement of special material.
