Abstract

The utility model relates to an improved welding device for steel rail bond, which is composed of a welding die 1, welding moulds 2 and 3, and flux boxes 4 and 5. The flux boxes 4 and 5 are respectively installed on the welding moulds 2 and 3. The edge between an upper flat surface and a lateral surface of the hexahedral welding mould is provided with a sprue 6, and the lateral surface is provided with a welding chamber 7 and a wiring groove 8. The welding device for steel rail bond has the advantages of easy operation, small size, light weight, convenient carrying, and increased safety, increased welding efficiency and improved welding work.

Description

Welding device for steel rail bond

The utility model relates to operation and transportation and technical field of fixed buildings, specifically a kind of welder that adopts aluminothermy welding process welded rails bond wire.

The rail bond of welding needs welder, and its advance and practicality show easy to carry, and volume is little, and is in light weight, simple to operate, and welding quality is good.Existing half a century, the welder that adopts of U.S. ERICO company of welded rails bond wire history was weldering mould, weldering die clamp, white fuse piece etc., the weldering die clamp will weld the die clamp dress and place on the welding position of rail, during welding, welding from fuse device on the bottom outlet of mould reative cell, solder flux packed into weld in the reative cell of mould, remove detonator to the solder flux surface again, igniting welding then.Because the weldering mould is the overall structure of top reaction compartment and melting welding chamber, bottom, when so rail bond is welded in each igniting, all to install from fuse piece, solder flux in the welding flux box to be poured in the melting welding chamber, also to clear up the welding slag shell that welds in the mould reative cell with scraper, thereby make the operational sequence of welded rails continuous lines various, influence welding work efficiency, when working continuously, operating personnel operate under the hot conditions of weldering mould, security incident takes place easily and influence welding quality, and the volume of weldering mould is bigger, weight is also bigger, carries and use all inconveniences.

The purpose of this utility model provides a kind of improved rail bond welder, to simplify the welding operation operation, improves the welding work efficiency, strengthen the security of weld job, and volume is little, and is in light weight, is easy to carry.

Realize that the purpose of this utility model is by the weldering die clamp, weldering mould, welding flux box are formed, weldering die clamp and two weldering die clamp dresses, the welding flux box device is on the weldering mould, the weldering mould is a hexahedron, has cast gate on the rib of a plane on it and a side, and has melting welding chamber and wire casing in this side.

Welding flux box is that interior device has solder flux and ignite material and fuse cord, and the inwall at the bottom of the box is curved surface or the plane that favours horizontal plane at the bottom of the box, and has bottom outlet on the box portion bottom wall near lower end, inclined plane and box side wall, is stained with on the bottom outlet from the fuse piece sealing of hole.

The utility model is owing to adopted disposable many with welding flux box and the weldering mould that has improved, during use, its operational sequence is very simple, shorten weld interval, improved the welding work efficiency, and avoided continued operation at high temperature, strengthened the security of rail bond weld job, and its volume is little, and is in light weight, uses and carries all very convenient.

Describe in detail below in conjunction with accompanying drawing of the present utility model.

Fig. 5, the right view of Fig. 4.

As shown in Figure 1, the both sides of weldering die clamp have clamped weldering mould 2 and 3 respectively, welding flux box 4 and 5 installs respectively on weldering mould 2 and 3, wherein weld mould 2 with 3 and welding flux box 4 identical with 5 structures, weldering mould 2 is a hexahedron, on the rib of a plane on it and a side, has cast gate 6, and on this side, also have melting welding chamber 7 and wire casing 8, have the groove 9(that is installed in its bottom surface) referring to Fig. 2; Lid 10 lids are connected on the

welding flux box

4,11 inwall is curved surface or the plane that favours horizontal plane at the bottom of the box at the bottom of the box, and have bottom outlet 13 on 11 at the bottom of near the box of lower end, inclined-plane and box side wall, be bonded on the bottom outlet 13 and sealing of hole from fuse piece 12, solder flux is housed and ignite material 14 and fuse cord 15 in the box body 4, near the outer end of bottom outlet 13,

Antileaking plate

16 and 11 fuse (referring to Fig. 3) at the bottom of the box; Weldering die clamp 1 is installed in the draw-in groove 9 of weldering mould 2, and the bottom outlet 14 of welding flux box 4 is aimed at the cast gate 6 on the weldering mould 2.Here, the weldering mould is selected refractory material making such as graphite for use, and welding flux box selects for use materials such as pottery or hard fire clay to make, and selects steel plate for use from fuse piece, and the copper coin material is made.

During welding, the two ends of bond wire 17 are inserted respectively in the wire casing 8 of weldering mould 2 and 3, to weld again on the welding position that mould 2 and 3 is installed in rail 18, during device, the plane, top of weldering mould should be lower than the rail tread, and the Antileaking plate 16 of welding flux box 4 and 5 bottom sides is chosen the fuse cord 15 in welding flux box 4 and 5 near the side of rail, and lid installs lid 10, light fuse cord 15, the high temperature metal solution that the solder flux 14 that ignites produces enters the weldering mould, and bond wire 17 and rail 18 are welded together, after surplus treating ten second, unload the weldering mould, remove the welding point cast gate, promptly finish the welding of a bond wire, as long as change the welding flux box in the utility model, but then continuous several times is used.
