[0038] The cushion group is arranged on the support body 1, and the cushion group is sleeved on the fixing group; the pressing group is sleeved on the fixing group. In the pressing state, the workpiece to be pressed is placed on the cushion group, and the workpiece to be pressed is pressed between the cushion group and the pressing group through the cooperation of the pressing group and the fixing group; specifically, the workpiece to be pressed is placed on the cushion group, and the workpiece to be pressed is limited through the cooperation of the pressing group and the fixing group; and subsequent welding operations are carried out after the limiting.
[0039] In addition, in the present utility model, a plurality of first bolts (not shown in the figure) pass through from one surface of the workbench 11 to the other surface of the workbench 11 and are connected to the cushion group; specifically, the cushion group is fixed on the workbench 11 through a plurality of first bolts to prevent the cushion group from moving during use; in addition, the number of the first bolts can be set as required. In the present utility model, preferably, there are 4.
[0040] As Figure 2 or Figure 4 shown, the cushion group includes a die blank 31 and a backing plate 32, and the die blank 31 is arranged on the support body 1; the backing plate 32 is arranged inside the die blank 31; during fixation, the die blank 31 is connected through a plurality of first bolts passing through the workbench 11; as Figure 4 shown, an installation ring 33 is arranged on the die blank 31, and the backing plate 32 is arranged inside the installation ring 33; ensuring that the backing plate 32 will not move on the die blank 31; in addition, a cavity is arranged inside the die blank 31, and the second bolts can be placed in the cavity, and the second bolts (not shown in the figure) pass through from one end of the die blank 31 to the installation ring 33 and are connected to the backing plate 32; this can further increase the firmness of the fixation of the backing plate 32; the number of the second bolts can be set as required. In the present utility model, preferably, there are 4.
[0041] As Figure 2As shown, the die blank 31 includes a fixing part 311 and a protruding part 312. The fixing part 311 is arranged on the support body 1, and the protruding part 312 is arranged on the fixing part 311. Specifically, a number of first bolts pass through the workbench 11 and then are connected to the fixing part 311. The second bolt passes through from one end of the protruding part 312 into the mounting ring 33 and is connected to the backing plate 32. At the same time, after the workpiece to be pressed is installed, the position of the workpiece to be pressed can be restricted by the protruding part 312 to prevent the workpiece to be pressed from moving. Additionally, to better adapt to the size of the workpiece to be pressed, preferably, the protruding part 312 is a frustum. In this way, even if the diameter of the workpiece to be pressed changes, the protruding part 312 can be adapted at different heights.
[0042] As Figure 2 shown in FIG. 3 or FIG. 4, the pressing group includes a first pressing ring 41 and a second pressing ring 42. The first pressing ring 41 is sleeved on the fixing group; the second pressing ring 42 is sleeved on the fixing group. In the pressing state, the first pressing ring 41 is connected to the cushion group through a number of third bolts 43; the second pressing ring 42 is placed inside the first pressing ring 41. When the workpiece to be pressed is placed on the cushion group, it is pressed on the workpiece to be pressed through the first pressing ring 41. And the second pressing ring 42 is placed inside the workpiece to be pressed. In this way, after the first pressing ring 41 is fixed to the cushion group through the third bolts 43 and the second pressing ring 42 is fixed through the fixing group, the movement of the workpiece to be pressed in both the horizontal and vertical directions can be restricted simultaneously.
[0043] As Figure 4 shown, the fixing group includes a screw rod 21 and a nut 22 arranged on the screw rod 21. Specifically, the screw rod 21 penetrates through the workbench 11, the die blank 31 and the second pressing ring 42.

[0045] In the present invention, the workpiece to be pressed is preferably: a flange 5 and a top cover 6. Among them, the inner diameter of the top cover 6 is selected to be 500 mm; the outer diameter of the flange 5 is selected to be 500 - 0.3 mm for the flange.
[0046] Before welding, the support body 1, the cushion group, the pressing group, the fixing group, the top cover 6 and the flange 5 are dried to eliminate the influence of water droplets on the welding quality. At the same time, the front and back sides of the top cover 6 and the flange 5 are also polished to remove the surface oxide film.
[0047] Connect the top cover 6 to the flange 5. Due to the size selection of the flange 5 and the top cover 6, the flange 5 and the top cover 6 are connected by interference fit.
[0048] Place the backing plate 32 into the mounting ring 33 on the protruding portion 312 and fix the backing plate 32 in the mounting ring 33 with the second bolt; Place the fixing portion 311 on the workbench 11 and connect the fixing portion 311 to the workbench 11 with the first bolt; Pass the screw rod 21 through the workbench 11 and the die blank 31 so that both ends of the screw rod 21 are respectively on both sides of the workbench 11 and the die blank 31; Place the assembled top cover 6 and flange 5; Place the top cover 6 on the protruding portion 312; Slip the second compression ring 42 onto the screw rod 21 and make the second compression ring 42 contact the top cover 6.
[0049] Tighten the nut 22 on the screw rod 21 and connect the third bolt 43 on the first compression ring 41 to the fixing portion 311; Thus, the positioning of the top cover 6 and the flange 5 is completed; Among them, an up-and-down force is formed through the cooperation of the workbench 11, the die blank 31, the backing plate 32, the first compression ring 41, the second compression ring 42 and the screw rod 21 to limit the displacement of the top cover 6 and the flange 5 in the vertical direction; The displacement of the flange 5 in the horizontal direction is restricted by the cooperation of the second compression ring 42 and the first compression ring 41; The displacement of the top cover 6 in the horizontal direction is restricted by the protruding portion 312; Therefore, the horizontal and vertical displacements of the top cover 6 and the flange 5 can be restricted through the overall structure.
[0050] Weld the flange 5 and the top cover 6, and after welding is completed, place them indoors for cooling. After cooling, clean and inspect.
[0051] Trim the weld seam to ensure a smooth transition between the top cover 6 and the flange 5.
[0052] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
