Problems solved by technology

[0005] However, the above-mentioned formal welding tool has the following defects: only the third profile 103 in the middle position is in contact with the corresponding third support plate 203, and the fifth profile 105 raised at the edge is pressed by the second clamping fixture 202 , the welding groove on the upper surface of the profile will be lifted instead, such as figure 2 and image 3 As shown, the groove of the fifth profile 105 is higher than the groove of the adjacent internal fourth profile 104, and the edge misalignment will occur during welding
[0013] Firstly, excessive positioning welding is performed on the weld seam, resulting in an increase in auxiliary time such as multiple arc welding and welding seam grinding, which reduces production efficiency; The side has a certain fixing effect, but it also restricts the free shrinkage deformation of the groove here. Once the wrong side occurs, it will be more difficult to adjust the wrong side
[0014] The second is that the whole groove is adjusted by hammering, which not only has high labor intensity and low adjustment efficiency, but also easily damages or dents the surface of the profile, resulting in a decrease in the strength of the profile

Embodiment 1

[0039] An embodiment of the present invention provides a tooling support plate, the support height at the edge of the tooling support plate is greater than the height of the corresponding position of the profile to be supported.

[0040] The support plate mainly refers to the support plate adjacent to the clamp at the top tight end in the formal welding tool. For other structures of the formal welding tool, please refer to figure 1shown. Of course, the tooling support plate can also be used in other places, and is used in the welding tooling where the arc profile has a radian position. For example, if necessary, the support plate can be used under the profile near the positioning end clamp, not limited to this Example.

[0041] The application principle of the support plate in the formal welding tool and welding method will be described in detail below by taking the support plate adjacent to the top tight end clamp as an example, and the principle and method of the support pl...

Embodiment 2

[0047] Embodiment 2 of the present invention also provides a formal welding tool, Figure 5 The schematic diagram of the overall assembly process of the curved profile workpiece provided by Embodiment 2 of the present invention, as shown in Figure 5 As shown, the formal welding tooling includes five sets of support plates, namely the first support plate 213, the second support plate 223, the third support plate 203, the fourth support plate 233 and the deformed support plate 243, and also includes the first pressing plate A jig 201 , a second pressing jig 202 , a positioning end jig 205 and a top tightening end jig 206 .

[0048] Of course, the number of sets of support plates depends on the number of profiles to be supported, usually the same as the number of profiles to be supported, each set of support plates supports one profile, and the support plates in each group can include multiple pieces of the same shape and size The support plate can also be a whole piece of supp...

Embodiment 3

[0054] Embodiment 3 of the present invention also provides a arc-shaped profile welding method, which can be implemented by using the formal welding tool provided in any embodiment of the present invention, and specifically includes the following steps:

[0055] The arc-shaped profile workpiece completed by reverse assembly welding is placed on the support plate of the formal welding tool, and clamped between the positioning end fixture and the top tightening end fixture, wherein the formal welding tool includes multiple support plates, the first pressing fixture, The second compression fixture, the positioning end fixture and the top tight end fixture, the support plate adjacent to the top tight end fixture is used as a deformed support plate, the support height at the edge of the deformed support plate is greater than the height of the corresponding position of the profile to be supported, and the deformed The edge of the support plate is located between the second clamping f...

Abstract

A fixture supporting plate, a forward assembly welding fixture and a method for welding an arc sectional material are disclosed. The supporting height at the edge of the fixture supporting plate is greater than the height at the corresponding position of the sectional material to be supported. The forward assembly welding fixture includes a deformable supporting plate (243) formed by the supporting plate which is adjacent to a resisting end clamp (206) and / or a locating end clamp (205). The method for welding the arc sectional material adopts above-mentioned forward assembly welding fixture during the welding process. The fixture supporting plate, the forward assembly welding fixture and the method for welding the arc sectional material can enhance the pressing-clipping effect of the fixture pressing clamp, and can control effectively the misalignment problem at the position of the butt joint groove of the long seam of the arc sectional material before welding without adjusting groove misalignment. The production efficiency of the long longitudinal seam arc sectional material is greatly improved.

Description

technical field [0001] The invention relates to profile welding and assembly technology, in particular to a frock support plate, formal welding frock and arc profile welding method. Background technique [0002] In the rail vehicle body structure, parts with curved profiles such as side walls and roofs are generally assembled with several profiles in the form of butt joints or lap joints, and then the long longitudinal welds of the connecting parts between adjacent profiles are welded Made into curved profile parts. [0003] With the continuous development of welding technology, the current long longitudinal welds are generally welded by automatic welding equipment such as welding robots or welding planes. Compared with the welding torch of manual welding machine, the welding torch of automatic welding equipment is generally larger in size, so it takes up a lot of space. Therefore, in the welding process, in order to leave a certain space, ensure that the welding torch can ...
