[0029] For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by showing examples of the present invention.

[0030] Figure 1 This is a three-dimensional diagram of an internal support tooling used for post-welding correction of a stainless steel rocket head according to an embodiment of the utility model; Figure 2 yes Figure 1 A partial enlarged view of Figure 3 It is a left view of an internal support tooling used for correcting the shape of a stainless steel rocket head after welding according to an embodiment of the utility model; Figure 4 The utility model is a top view of an internal support tooling used for correcting the shape of a stainless steel rocket head after welding according to an embodiment of the utility model.

[0031] like Figure 1 As shown, the utility model provides an internal support tooling for stainless steel rocket head after welding correction, including: an internal support base 1-1 and an internal support 1-5, the internal support 1-5 is arranged on the internal support base 1-1, and the internal support 1-5 is used to support the weld from the inside of the tank. The internal support 1-5 can move relative to the internal support base 1-1 to get close to or away from the weld.

[0032] The internal support tooling of this embodiment supports the longitudinal seams of the tank (such as the longitudinal seams of the melon slices of the head) from the inside of the tank (such as the inner side of the head), and cooperates with the rolling equipment to roll and level the longitudinal seams, which can improve the rolling effect and weld performance. The internal support 1-5 moves relative to the internal support base 1-1, away from the weld, to provide space for the rotation of the melon slices or the head. The side of the internal support 1-5 used to support the weld can adopt a contoured design, that is, its arc surface matches the inner surface of the short cylinder or the head. For example, the thickness of the internal support 1-5 can be 30~60mm.

[0033] According to one embodiment of the utility model, the inner support base 1-1 is provided with an inner support base guide rail 1-3, and the inner support 1-5 can move along the inner support base guide rail 1-3 to get closer to or away from the weld.

[0034] In this embodiment, the setting travel direction of the inner support base guide rail 1-3 is the radial direction of the melon slice or the head. The inner support base guide rail 1-3 can provide guidance and limit for the inner support 1-5.

[0035] According to one embodiment of the utility model, the inner support base 1-1 is provided with a stopper 1-10, and the inner support 1-5 is provided with a limit block 1-4 on the side opposite to the stopper 1-10. When the inner support 1-5 moves to the rolling position, the limit block 1-4 is blocked by the stopper 1-10, limiting the movement of the inner support 1-5.

[0036] like Figure 1 and 2 As shown, according to one embodiment of the utility model, the inner support base 1-1 is provided with a limit drive cylinder 1-2. The stopper 1-10 is provided on the telescopic rod of the limit drive cylinder 1-2. When the limit drive cylinder 1-2 is started, the stopper 1-10 is extended or retracted through the extension of the telescopic rod to limit or release the limit of the limit block 1-4.

[0037] In this embodiment, when the inner support 1-5 moves to the rolling position, the limit drive cylinder 1-2 is started, and the telescopic rod is extended, so that the stopper 1-10 limits the inner support 1-5 through the limit block 1-4, thereby preventing the inner support 1-5 from moving during the entire rolling process. The limit drive cylinder 1-2 can be a pneumatic cylinder, and the telescopic rod can be arc-shaped. The limit block 1-4 can be L-shaped.

[0038] According to one embodiment of the present utility model, the limit drive cylinder 1-2 can be arranged inside the inner support base 1-1.

[0039] In this embodiment, when there is no need to limit the inner support 1-5 or the limit block 1-4, the stop block 1-10 can be pulled back into the interior of the inner support base 1-1 by the telescopic rod.

[0040] According to one embodiment of the utility model, the stopper 1-10 is arranged on the outer side of the inner support base rail 1-3. A rectangular hole 1-11 is arranged on the side of the inner support base rail 1-3 facing the stopper 1-10 along the moving direction of the inner support 1-5. The limit block 1-4 extends out from the rectangular hole 1-11, and the limit block 1-4 can move along the length direction of the rectangular hole 1-11.

[0041] like Figure 3 and 4 As shown, according to one embodiment of the utility model, the inner support base 1-1 is provided with a linear gear guide rail 1-7, and the inner support 1-5 is provided with a gear 1-9 meshing with the linear gear guide rail 1-7. The gear 1-9 moves along the linear gear guide rail 1-7, driving the inner support 1-5 to move along the inner support base guide rail 1-3.

[0042] According to one embodiment of the utility model, the inner support 1-5 is provided with a gear drive motor 1-8, and the gear 1-9 is installed on the rotating shaft of the gear drive motor 1-8. When the gear drive motor is started 1-8, the driving shaft drives the gear 1-9 to move along the inner support base guide rail 1-3.

[0043] According to one embodiment of the utility model, the linear gear guide rail 1-7 is arranged in parallel with the inner support base guide rail 1-3.

[0044] In this embodiment, the linear gear guide 1-7, the gear drive motor 1-8 and the gear 1-9 cooperate to achieve linear movement of the inner support 1-5 relative to the inner support base guide 1-3.

[0045] According to one embodiment of the utility model, a lock buckle 1-6 is provided at the top end of the inner support, and the lock buckle 1-6 is used to lock with the external rolling equipment.

[0046] In this embodiment, when the longitudinal seam of the short tube or the head melon slice is rolled, the locking buckle 1-6 is locked with the external rolling equipment, and the rolling equipment and the inner support 1-5 are locked to ensure the rolling effect of the external rolling equipment.

[0047] According to an embodiment of the utility model, in addition to the inner support base 1-1 and the inner support 1-5, the inner support tooling also includes a top cover column arranged in the middle of the head. The top cover column is used to lock with the external rolling equipment and cooperate with the external rolling equipment to roll the annular seam of the head.

[0048] In this embodiment, the top cover column is locked with the external rolling equipment, which can ensure the rolling effect of the external rolling equipment on the head ring seam.

[0049] The above-mentioned embodiments of the present invention can be combined with each other and have corresponding technical effects.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
