Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary tools, in particular to a heat-resistant steel welding wire. Background Art

[0002] A welding wire is a welding material in the form of a metal wire used as a filler metal or simultaneously as a conductor for electricity, including carbon steel welding wires, low-alloy structural steel welding wires, alloy structural steel welding wires, stainless steel welding wires, non-ferrous metal welding wires, etc. The surface of the welding wire is not coated with a flux for anti-oxidation. During gas welding and tungsten inert gas shielded arc welding, it is used as a filler metal. Therefore, when welding heat-resistant steel materials, a heat-resistant steel welding wire is used.

[0003] The existing heat-resistant steel welding wires still have the following problems when in use: Most of them adopt a single-material welding wire structure design of a single strip. They are usually directly wound on a winch for storage. There is a lack of protection on the outside of the welding wire itself, making it extremely easy to oxidize or wear, resulting in damage to the welding wire body. At the same time, since the welding wire body is made of heat-resistant steel material, it often needs to be used with a flux. That is, during transportation, the welding wire and the flux often need to be transported separately, which is rather inconvenient. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a heat-resistant steel welding wire, which solves the problems put forward in the background art.

[0005] To achieve the above object, the utility model provides the following technical solution: A heat-resistant steel welding wire includes a welding wire mechanism; a winch mechanism for winding the welding wire mechanism. The winch mechanism includes a winch disc body. The welding wire mechanism includes a rubber sheath wound around the outside of the winch disc body, and a welding wire main body is slidably fitted to the inner wall of the rubber sheath.

[0006] As a further scheme of the utility model: The welding wire main body is a heat-resistant steel welding wire strip slidably fitted to the inner wall of the rubber sheath. A group of through holes are opened in the middle of the heat-resistant steel welding wire strip. The group of through holes are three and are arranged at equal distances from front to back. A fitting groove is opened in the middle of the outer side walls at the upper and lower ends of the heat-resistant steel welding wire strip, and a solid flux strip is fixedly connected in the fitting groove. The separated ends of the two solid flux strips are slidably fitted to the inner wall of the rubber sheath.

[0007] As a further scheme of the utility model: An annular groove is opened on the periphery of the outer side walls at the front and rear ends of the winch disc body. The two annular grooves are arranged symmetrically front and back, and a group of reinforcing blocks are fixedly connected to the inner side walls at the opposite ends of the two annular grooves. The group of reinforcing blocks are multiple and are arranged at equal distances in a ring shape.

[0008] As a further solution of the present utility model: in the middle of the annular inner wall of the winch disc body, three hollow frames are fixedly connected in an annular equidistant manner. One connecting seat is fixedly connected to the opposite ends of the three hollow frames. An axial mating hole is formed between the central positions of the front and rear side walls of the connecting seat, and a keyway is formed at the top of the axial mating hole. An arc-shaped reinforcing frame is fixedly connected between the outer side walls of every two adjacent hollow frames on the opposite sides, and the three arc-shaped reinforcing frames are arranged in an annular equidistant manner.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] 1. In the present utility model, a rubber sheath is arranged on the outer side of the welding wire main body. When the welding wire main body is wound on the winch mechanism, in addition to the protection of the welding wire main body by the winch mechanism, the rubber sheath on the outer side of the welding wire main body can also provide good protection to reduce the oxidation and wear of the welding wire main body of the welding wire mechanism.

[0011] 2. In the present utility model, the welding wire main body adopts a soldering aid structure design. The welding wire main body includes a heat-resistant steel welding wire strip. Fitting grooves are formed at the upper and lower ends of the heat-resistant steel welding wire strip, and solid soldering aid strips are fixedly connected in the fitting grooves. At the same time, a plurality of through holes are formed in the middle of the heat-resistant steel welding wire strip to facilitate gas circulation. When the overall welding wire main body is heated and melted, it is easier to melt compared with the single-material heat-resistant steel welding wire structure. Moreover, during transportation, it is not necessary to transport the welding wire and the soldering aid separately, which is more convenient. Description of the Drawings

At the same time, a plurality of through holes 122 are provided in the middle of the heat-resistant steel welding wire strip 121 to facilitate gas flow. When the whole welding wire main body 12 is heated and melted, it is easier to melt compared with the structure of a single-material heat-resistant steel welding wire. And when transporting, it is not necessary to transport the welding wire and the soldering flux separately, which is more convenient.

[0020] Circular grooves 22 are respectively provided on the peripheries of the outer side walls at the front and rear ends of the winch body 21. The two circular grooves 22 are arranged symmetrically from front to back. The circular grooves 22 play a role in reducing the weight of the winch body 21.

The group of reinforcing blocks 23 are multiple and are arranged at equal distances in a ring shape.

[0021] In the middle of the annular inner wall of the winch body 21, three hollow frames 24 are fixedly connected in an annular equidistant manner. The opposite ends of the three hollow frames 24 are fixedly connected to the same connecting seat 25.
