Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, and specifically to a welded backplate equipped with a circulating water function. Background Technology

[0002] With the rapid development of EMU technology and the increase in train operating speed, the design of the car body structure is becoming more and more mature. In the future, it will be possible to upgrade the overall technology by not changing the large components of the car body, but only changing the small parts assembled on the car body. This shows the importance and complexity of the small parts.

[0003] As a crucial component of aluminum alloy EMU trains, the internal components require rigorous internal quality control for every weld, aesthetically pleasing appearance on both sides of the weld, and conformity to the design drawings for each part's shape. These components are structurally complex, involve numerous welds, and experience significant deformation during welding. Designers typically design single-sided beveling of the base material (in the industry, this refers to HV welds), requiring single-sided welding with double-sided forming. To enhance the aesthetics of the weld's back-view appearance, designers often employ a single-sided weld with a removable welding backplate (removable welding backplate designation: MR). However, currently, there is a lack of suitable manufacturing tooling for this purpose.

[0004] Therefore, to meet practical needs, a welded backplate with a circulating water function is provided. Summary of the Invention

[0049] In summary, the technical solution of this application provides an auxiliary tooling for a welding backplate with circulating water function for HV+MR welds, proposing a highly practical and efficient welding backplate. The auxiliary tooling is highly practical and has a significant anti-deformation effect, greatly reducing welding deformation. Furthermore, this application provides some experience and reference for similar welding structures.

[0050] Furthermore, the design aims to propose a novel welding backplate with circulating water function to specifically address the problem of excessive workpiece deformation caused by high heat input during HV+MR welding of aluminum alloys. The goal is to create a practical welding auxiliary process equipment with significant anti-deformation effects, effectively solving the problem of excessive workpiece deformation due to high heat input during HV+MR welding, reducing the intensity of post-weld shaping work, and improving production efficiency. The auxiliary tooling includes a water tank 1, a submersible pump 2, and the first metal extension pipes 4, first main water pipe 5, second main water pipe 6, and F-type clamps 8 inside the welding backplate 3.

[0052] When the submersible pump 2 is started before welding, a large amount of circulating water flows in the welding back plate 3, which effectively removes the heat around the weld, reduces welding deformation, reduces the amount of adjustment work, and saves time.

[0053] Each of the first metal extension tubes 4 is used for the first main water pipe 5 and the second main water pipe 6. The first main water pipe 5 and the second main water pipe 6 can be made of commonly used rubber water pipes on the market, which are highly flexible and can be used in various complex environments.

[0054] Adapter 7 uses a multi-functional quick connector, which effectively improves the installation efficiency of the hose;

[0055] Submersible pump 2 is the type of submersible pump used in medium to large-sized aquariums, with appropriate power and easy to purchase.
