[0033] A forming device for supporting a plate during welding is provided in the embodiment. As shown in Figs. 1-3As shown, the device comprises a base 10 and a support structure 20, wherein the base 10 is arranged at the machining station along a first direction, and the length direction of the plate 100 is the same as the first direction during welding; the support structure 20 is arranged at both ends of the length direction of the base 10, and the support structure 20 is vertically connected to the base 10, the top surface 21 of the support structure 20 and the side walls 22 on both sides along the length direction can abut and support the plate 100, so that the plates 100 and the support structure 20 can be welded and formed into a workpiece 200.
[0034] In this device, the support structure 20 is vertically arranged at both ends of the length direction of the base 10, and the length direction of the plate 100 is the same as the length direction of the base 10 during welding, which ensures that both ends of the plate 100 can abut the top surface 21 and the side wall 22 of the support structure 20, and can play a good supporting and position reference role. Specifically, during welding, a plate 100 can be placed on the top surface 21 of the two support structures 20 for welding, and then the remaining plates 100 can be abutted to the side wall 22 and the above-mentioned plate 100 to continue welding, which is simple and convenient to operate, thereby effectively reducing the manufacturing cost and improving the forming quality.
[0035] It should be noted that in this embodiment, the workpiece 200 is formed by welding the plates 100 and the forming device, so that the base 10 can ensure the stability during welding, and the support structure 20 and the base 10 are vertically arranged to reduce the operation difficulty and improve the operability.
[0036] In addition, as shown, Figs. 1-3 The length direction of the support structure 20 is perpendicular to the first direction. This arrangement can further reduce the welding difficulty of the top surface 21 and the plate 100, facilitate the position comparison and reference during welding of the side wall 22 and the plate 100, and also improve the appearance of the workpiece 200.
[0037] It should be noted that the C-shaped steel beam in the prior art is mostly formed by splicing three plates 100, and the included angle between the two adjacent plates 100 is too large (about 90°), which can cause the welding seam to easily leak, thereby reducing the forming quality. To solve this problem, as shown, Fig. 1As shown, the support structure 20 includes a first side surface 221 and a second side surface 222 on each of the two side walls 22 along the length direction thereof, the first side surface 221 is connected to the base 10 perpendicularly, and the second side surface 222 is connected to the first side surface 221 at one end and to the top surface 21 at the other end, the distance between the two first side surfaces 221 remains unchanged in the vertical direction, and the distance between the two second side surfaces 222 gradually decreases in the direction away from the base 10. In this structure, the first side surface 221 is arranged perpendicularly and not inclined to the base 10, and one side of the plate 100 can be abutted against the first side surface 221, and one side can be placed vertically on the base 10 for welding, which greatly reduces the operation difficulty and improves the operation efficiency. In addition, the distance between the two second side surfaces 222 gradually decreases in the direction away from the base 10, that is, the two second side surfaces 222 are inclined towards each other, at this time, one side of the plate 100 can be abutted against the second side surface 222 and welded and fixed, and then the plate 100 and other plates 100 adjacent thereto are welded again, which ensures the convenience of welding. Most importantly, this arrangement realizes the welding of multiple plates 100 to form a workpiece 200, effectively reduces the included angle between two adjacent plates 100, thereby reducing the risk of weld leakage, and greatly improves the forming quality of the workpiece 200.
[0038] It should be noted that in the present embodiment, the workpiece 200 is formed by welding five plates 100 and a forming device, and the included angle between the plate A, the plate B and the base 10 is 45° by using the above support structure 20; the included angle between the plate C and the plate A and the included angle between the plate D and the plate B are also 45°, and the included angle between the plate E and the plate C and the included angle between the plate E and the plate D are both 60°, and the included angle between each plate 100 is less than 90°, which not only greatly reduces the welding angle, thereby effectively reducing the risk of weld leakage, but also avoids the problem that the welding head cannot smoothly extend in when the angle is too small. In other embodiments, the number of plates 100 can be adjusted according to actual needs, and a third side surface and a fourth side surface can be added in correspondence with the number of plates 100, as long as the included angle between two adjacent plates 100 is not too large or too small, and the present embodiment is not limited in other ways.

Specifically, when the angle welding of the plate 100 is carried out, TIG welding is used for bottoming, then MIG welding is used for filling, and finally the surface is treated by TIG welding, and at least two layers are welded at each step, and the oxide skin and foreign matter are removed by using acetone to clean between layers, so as to ensure good airtightness.
[0040] In order to ensure that the workpiece 200 has good heat exchange and heat conduction performance when in use, as shown in the figure, the support structure 20 is provided with a notch 23 along the first direction. This kind of setting can facilitate the heat exchange of the inside of the workpiece 200, and ensure its good use effect. In addition, it can also reduce the overall quality of the support structure 20, which is beneficial to save cost. Figs. 1-3
[0041] In order to solve this problem, as shown in the figure, the base 10 is also provided with a fixing rib 30, and the fixing rib 30 is used to fix the support structure 20. By setting the fixing rib 30, the problem of stability decline caused by the reduction of the mass of the support structure 20 can be made up. In addition, the fixing rib 30 is arranged at both ends of the support structure 20 along the length direction.
