[0045] like Figure 1-3 As shown in Figure 13, the present invention provides a rolling equipment used for the post-welding correction of stainless steel rocket heads, including: an external pressure component 2-3. The external pressure component 2-3 includes a rolling mechanism 2-3-4 and an external pressure component frame 2-3-1. The rolling mechanism 2-3-4 includes a rolling mechanism frame 2-3-4-6 and a rolling wheel 2-3-4-1. The rolling wheel 2-3-4-1 is arranged on the rolling mechanism frame 2-3-4-6. The rolling mechanism frame 2-3-4-6 is slidably connected to the inner side surface of the external pressure component frame 2-3-1, and the rolling wheel 2-3-4-1 can rotate relative to the rolling mechanism frame 2-3-4-6, so that the rolling wheel 2-3-4-1 rolls along the longitudinal weld of the tank to roll the longitudinal weld of the tank. The inner side surface of the external pressure component frame 2-3-4-6 is a profile that matches the tank.

[0046] In this embodiment, the rolling wheel 2-3-4-1 can move along the inner side of the external pressure component frame 2-3-1 (i.e., the side of the rolling mechanism frame 2-3-4-6 facing the tank) to roll along the longitudinal weld of the tank. The external pressure component frame 2-3-1 can be roughly triangular as a whole, such as a right triangle. The inner side of the external pressure component frame 2-3-1 adopts a profiling structure, which can be adapted to the outer shape of the tank (head melon slice). For example, the inner side of the external pressure component frame 2-3-1 can be an elliptical arc surface structure, and its arc surface characteristics are consistent with the arc surface characteristics of the head melon slice.

[0047] like Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, in addition to the rolling mechanism 2-3-4 and the external pressure component frame 2-3-1, the external pressure component 2-3 also includes a conveying mechanism 2-3-6. The conveying mechanism 2-3-6 includes a conveyor belt 2-3-6-1 arranged on the external pressure component frame 2-3-1, and the conveyor belt 2-3-6-1 is fixedly connected to the rolling mechanism frame 2-3-4-6. The conveyor belt 2-3-6-1 is used to drive the rolling mechanism 2-3-4 to move along the inner side of the external pressure component frame 2-3-1.

[0048] In this embodiment, the conveyor belt 2-3-6-1 can be a flexible conveyor belt.

[0049] According to one embodiment of the present invention, the external pressure component frame 2-3-1 is provided with a rotatable transmission guide wheel 2-3-6-3, and the conveyor belt 2-3-6-1 is sleeved on the transmission guide wheel 2-3-6-3.

[0050] In this embodiment, for example, the transmission guide wheel 2-3-6-3 can be installed on the rolling bearing sleeve of the external pressure component frame 2-3-1. A transmission guide wheel 2-3-6-3 can be set at each end of the external pressure component frame 2-3-1, for example, a transmission guide wheel 2-3-6-3 is set near each of the three corners of the external pressure component frame 2-3-1 that is triangular in shape as a whole.

[0051] like Figure 5-7 As shown, according to one embodiment of the present invention, the two ends of the conveyor belt 2-3-6-1 are connected by a conveyor belt linker 2-3-6-2, and the rolling mechanism frame 2-3-4-6 is fixedly connected to the conveyor belt linker 2-3-6-2.

[0052] In this embodiment, for example, both ends of the conveyor belt 2-3-6-1 can be locked with the conveyor belt linker 2-3-6-2 by locking screws 2-3-6-2-1 (such as four screws). A circular hole can be opened in the middle of the conveyor belt linker 2-3-6-2 for connecting with the rolling mechanism frame 2-3-4-6.

[0053] like Figure 2 , 4 , 8 and 9, according to one embodiment of the present invention, the external pressure component 2-3 also includes a conveyor belt drive mechanism 2-3-5 arranged on the external pressure component frame 2-3-1. The conveyor belt drive mechanism 2-3-5 includes a conveyor belt drive motor 2-3-5-1 and a conveyor belt drive guide wheel 2-3-5-2, and the conveyor belt drive motor 2-3-5-1 is fixedly connected to the conveyor belt drive guide wheel 2-3-5-2. The conveyor belt 2-3-6-1 is sleeved on the conveyor belt drive guide wheel 2-3-5-2. The conveyor belt drive motor 2-3-5-1 is started to drive the conveyor belt drive guide wheel 2-3-5-2 to drive the conveyor belt 2-3-6-1 to rotate.

[0054] In this embodiment, the conveyor belt drive mechanism 2-3-5 can be installed on the external pressure component frame 2-3-1 through the drive motor flange 2-3-5-3. For example, the conveyor belt drive mechanism 2-3-5 can be installed on the rolling bearing seat 2-3-9-1 of the external pressure component frame 2-3-1. The conveyor belt drive mechanism 2-3-5 can be arranged at the right angle of the external pressure component frame 2-3-1 in a right-angled triangle, and the two transmission guide wheels 2-3-6-3 are arranged at the acute angle. The conveyor belt drive guide wheel 2-3-5-2 can be arranged on the rotating shaft of the conveyor belt drive motor 2-3-5-1. The rolling equipment can drive the conveyor belt 2-3-6-1 through the conveyor belt drive motor 2-3-5-1 to drive the rolling mechanism 2-3-4 to move along the external pressure component frame 2-3-1 (for example, uniform motion).

[0055] like Figure 3As shown, according to one embodiment of the present invention, the rolling mechanism frame 2-3-4-6 is provided with a rotating driving component 2-3-4-3. The rotating driving component 2-3-4-3 is provided with a rotating motor and a rotatable rotating shaft, and the rolling wheel 2-3-4-1 is connected to the rotating shaft. When the rotating motor is started, the rotating shaft is driven to drive the rolling wheel 2-3-4-1 to rotate, so as to roll the welds in different directions.

[0056] The rolling device of this embodiment can adjust the orientation of the rolling wheel 2-3-4-1 by the rotating motor to achieve the rolling of the short cylinder longitudinal seam and the butt annular seam between the short cylinder and the head. For example, the rotating motor can rotate at least 110°. The rotating motor can be connected to the rolling mechanism frame 2-3-4-6 by screws, rivets or welding. The axis of the rotating motor can coincide with the axis of the rolling mechanism frame 2-3-4-6.

[0057] According to one embodiment of the present invention, the rolling mechanism frame 2-3-4-6 is provided with a telescopic thrust drive cylinder component 2-3-4-2. The telescopic thrust drive cylinder component 2-3-4-2 includes a telescopic rod and a drive cylinder, and the rolling wheel 2-3-4-1 is connected to the drive cylinder via the telescopic rod. When the drive cylinder is started, the drive telescopic rod drives the rolling wheel 2-3-4-1 to approach or move away from the weld by telescoping.

[0058] In this embodiment, for example, the telescopic thrust electric cylinder component 2-3-4-2 can be connected to the rotating shaft of the rotating drive component 2-3-4-3 by screws or pins. The rolling wheel 2-3-4-1 can be installed on the wheel seat of the telescopic rod of the telescopic thrust electric cylinder component 2-3-4-2 by pins. The central axis of the telescopic thrust electric cylinder component 2-3-4-2 (for example, the central axis of the telescopic rod) can coincide with the axis of the rotating shaft of the rotating drive component 2-3-4-3.

[0059] According to one embodiment of the present invention, the telescopic thrust electric cylinder component 2-3-4-2 can be arranged on the rotating shaft of the rotating driving component 2-3-4-3, and the rolling wheel 2-3-4-1 is arranged on the telescopic rod of the telescopic thrust electric cylinder component 2-3-4-2. The rotating motor of the rotating driving component 2-3-4-3 is started, and the rotating shaft is driven to drive the telescopic thrust electric cylinder component 2-3-4-2 and the rolling wheel 2-3-4-1 to rotate, so as to roll the welds in different directions.

[0060] According to one embodiment of the present invention, a rolling groove 2-3-4-7 is provided on the inner side of the external pressure component frame 2-3-1. A radially locking upper guide wheel component 2-3-4-5 and a radially locking lower guide wheel component 2-3-4-4 are provided on one end of the rolling mechanism frame 2-3-4-6 away from the rolling wheel 2-3-4-1. The radially locking upper guide wheel component 2-3-4-5 is provided inside the rolling groove 2-3-4-7, and the radially locking lower guide wheel component 2-3-4-4 is provided on the outer side of the rolling groove 2-3-4-7. The radially locking upper guide wheel component 2-3-4-5 is provided with a rotatable upper guide wheel, and the radially locking lower guide wheel component 2-3-4-4 is provided with a rotatable lower guide wheel, and the upper guide wheel and the lower guide wheel synchronously roll along the inner and outer sides of the rolling groove 2-3-4-7 to provide guidance for the movement of the rolling wheel 2-3-4-1.

[0061] In this embodiment, the rolling mechanism 2-3-4 moves along the rolling groove 2-3-4-7 under the driving action of the conveyor belt 2-3-6-1, and the rolling wheel 2-3-4-1 rolls along the weld (longitudinal weld) and applies pressure to the weld to correct the weld deformation and eliminate the excess height of the weld. The rolling groove 2-3-4-7 cooperates with the radial locking upper guide wheel component 2-3-4-5 and the radial locking lower guide wheel component 2-3-4-4 to achieve radial limitation of the rolling mechanism 2-3-4. In addition, the rolling groove 2-3-4-7 can provide a motion track and radial support for the radial locking upper guide wheel component 2-3-4-5. For example, the rolling groove 2-3-4-7 can be an elliptical arc groove. The rolling groove 2-3-4-7 can be a through structure with a T-shaped cross section (i.e., through the thickness direction of the external pressure component frame 2-3-1), and the upper guide wheel is arranged at the top of the T-shaped through structure. The rolling groove 2-3-4-7 can be roughly an elliptical arc surface, parallel to the side of the external pressure component frame 2-3-1 relative to the short cylinder. The groove width of the rolling groove 2-3-4-7 can be 40-80mm. The upper guide wheel and the lower guide wheel can be rolling bearings.

[0062] According to one embodiment of the present invention, a conveyor belt groove 2-3-4-8 is provided on the inner side surface of the external pressure component frame 2-3-1, and the conveyor belt groove 2-3-4-8 is used to provide a conveying space for the conveyor belt 2-3-6-1.

[0063] In this embodiment, for example, two conveyor belt grooves 2-3-4-8 are arranged on the inner side of the external pressure component frame 2-3-1, and the two conveyor belt grooves 2-3-4-8 are arranged on both sides of the rolling groove 2-3-4-7. The groove width of the conveyor belt groove 2-3-4-8 can be 40-80 mm.

[0064] like Figure 4 As shown, according to one embodiment of the present invention, the external pressure component 2-3 is provided with two sets of conveying mechanisms 2-3-6, and the rolling mechanism frame 2-3-4-6 is provided between the two sets of conveyor belts 2-3-6-1.

[0065] In this embodiment, for example, two sets of conveying mechanisms 2-3-6 can be respectively arranged on two side surfaces of the external pressure component frame 2-3-1. The external pressure component frame 2-3-1 can adopt a symmetrical structure in the thickness direction.

[0066] According to one embodiment of the present invention, for example, a left cover plate 2-3-9 and a right cover plate 2-3-10 may be respectively provided on both sides of the external pressure component frame 2-3-1 to increase the structural strength of the external pressure component frame 2-3-1.

[0067] According to one embodiment of the present invention, for example, the driving motor flange 2-3-5-3 of the conveyor belt driving mechanism 2-3-5 can be connected to the left cover plate 2-3-9 or the right cover plate 2-3-10 by screws.

[0068] like Figure 2 , 4 , 11 and 12, according to one embodiment of the present invention, the external pressure component also includes a conveyor belt clamping guide wheel 2-3-7 and a conveyor belt locking mechanism 2-3-8. The conveyor belt locking mechanism 2-3-8 is fixedly connected to the external pressure component frame 2-3-1, and the conveyor belt clamping guide wheel 2-3-7 is arranged between the conveyor belt locking mechanism 2-3-8 and the conveyor belt 2-3-6-1. The conveyor belt clamping guide wheel 2-3-7 is provided with a rotatable clamping wheel, and the clamping wheel is in contact with the conveyor belt 2-3-6-1. The conveyor belt locking mechanism 2-3-8 is provided with a fastener, and the fastener is tightened to press the conveyor belt clamping guide wheel 2-3-7, so that the clamping wheel clamps the conveyor belt 2-3-6-1.

[0069] The rolling equipment of this embodiment can adjust the locking degree of the conveyor belt 2-3-6-1 by the conveyor belt locking mechanism 2-3-8 by adjusting the fastener. For example, the conveyor belt pressing guide wheel 2-3-7 and the conveyor belt locking mechanism 2-3-8 can be arranged at a right angle of the external pressure component frame 2-3-1 in a right-angled triangle. The fastener can be a screw, and the pressure applied by the fastener to the conveyor belt pressing guide wheel 2-3-7 can be adjusted by adjusting the tightening degree of the fastener. The conveyor belt locking mechanism 2-3-8 can be fixed to the external pressure component frame 2-3-1 by screws.

[0070] like Figure 1 and 13 As shown, according to one embodiment of the present invention, in addition to the external pressure component 2-3, the rolling equipment also includes an external pressure guide component. The external pressure guide component includes an external pressure base guide rail 2-1 and a base bracket 2-2, and the base bracket 2-2 is connected to the external pressure component frame 2-3-1. The base bracket 2-2 can move along the external pressure base guide rail 2-1 to drive the external pressure component 2-3 to approach or move away from the weld.

[0071] In this embodiment, the two sides of the external pressure component frame 2-3-1 are respectively provided with a left connecting plate 2-3-2 and a right linking plate 2-3-3 near the external pressure guide component, and the base bracket 2-2 is fixedly connected to the external pressure component frame 2-3-1 through the left connecting plate 2-3-2 and the right linking plate 2-3-3. For example, the left connecting plate 2-3-2 and the right linking plate 2-3-3 can be fixedly connected to the left cover plate 2-3-9 and the right cover plate 2-3-10 respectively. The external pressure guide component can be provided with multiple external pressure base guide rails 2-1.

[0072] like Figure 1 , 13 As shown in Figure 14, according to one embodiment of the present invention, the rolling equipment further comprises a weld inner support component 1. The weld inner support component 1 comprises an inner support base 1-1 and an inner support 1-5, the inner support 1-5 is arranged on the inner support base 1-1, and the inner support 1-5 is used to support the weld from inside the tank.

[0073] In this embodiment, the weld inner support component 1 cooperates with the external pressure component 2-3 to realize the rolling and leveling of the longitudinal weld of the head or short tube. The side of the inner support 1-5 used to support the weld can be designed in a profiling manner, that is, its arc surface matches the inner surface of the short tube or the head. For example, the thickness of the inner support 1-5 can be 30-60 mm.

[0074] According to one embodiment of the present invention, the inner support 1-5 can move relative to the inner support base 1-1 to get closer to or farther away from the weld.

[0075] In this embodiment, the inner support 1-5 moves relative to the inner support base 1-1 and away from the weld, thereby providing space for the rotation of the melon slices or the head.

[0076] like Fig.14 As shown, according to one embodiment of the present invention, 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 approach or move away from the weld.

[0077] 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.

[0078] According to one embodiment of the present invention, the inner support base 1-1 is provided with a limit drive cylinder 1-2. The inner support 1-5 is provided with a limit block 1-4 corresponding to the limit drive cylinder 1-2. When the inner support 1-5 moves to the rolling position, the limit drive cylinder 1-2 extends, and the inner support 1-5 is limited by the limit block 1-4.

[0079] In this embodiment, a rectangular hole may be provided on the side of the inner support base guide rail 1-3 facing the limit drive cylinder 1-2, and a limit block 1-4 may be provided on the side of the inner support 1-5 facing the rectangular hole, and the limit block 1-4 extends out of the rectangular hole. The limit drive cylinder 1-2 may be a pneumatic cylinder. The limit block 1-4 may be L-shaped. The limit drive cylinder 1-2 may include a telescopic cylinder and a (circular arc-shaped) limit rod. When the inner support 1-5 reaches the rolling position, the telescopic cylinder extends to push the limit rod out to block the limit block 1-4, so that the inner support 1-5 does not move during the entire rolling process.

[0080] like Fig.15 As shown, 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.

[0081] In this embodiment, the linear gear guide 1-7 is parallel to the inner support base guide 1-3. The gear 1-9 can be installed on the rotating shaft of the gear drive motor 1-8 to be driven by the gear drive motor 1-8. The linear gear guide 1-7, the gear drive motor 1-8 and the gear 1-9 cooperate to achieve the linear motion of the inner support 1-5 relative to the inner support base guide 1-3.

[0082] like Figure 2 , 14 As shown in Figures 16 and 16, according to one embodiment of the present invention, a vertical locking mechanism 2-3-12 is provided at the top of the external pressure component frame 2-3-1 near the tank, and a lock buckle 1-6 cooperating with the vertical locking mechanism 2-3-12 is provided at the top of the inner support 1-5. The vertical locking mechanism 2-3-12 includes an annular rotating rod 2-3-12-3 and a rotating driving machine 2-3-12-2. The rotating driving machine 2-3-12-2 is started to drive the annular rotating rod 2-3-12-3 to rotate, so that the annular rotating rod 2-3-12-3 is locked or disengaged with the lock buckle 1-6, and the external pressure component frame 2-3-1 is locked or unlocked with the inner support 1-5.

[0083] In this embodiment, when the longitudinal seam of the short tube or the head melon slice is rolled, the rolling mechanism frame 2-3-4-6 and the inner support 1-5 are locked by the annular rotating rod 2-3-12-3 and the lock buckle 1-6, thereby ensuring the rolling effect of the rolling mechanism.

[0084] For example, the rotary drive machine 2-3-12-2 can be a motor. The rotary drive machine 2-3-12-2 can be rotatably connected to the external pressure component frame 2-3-1 through the rotary motor base 2-3-12-1. The lock buckle 1-6 can be set on the top of the non-rolling surface (i.e., the vertical surface) of the inner support 1-5. The annular rotating rod 2-3-12-3 can be an annular rod with an opening, one end of the opening is connected to the rotating shaft of the rotary drive machine 2-3-12-2, and is connected to one side of the external pressure component frame 2-3-1 (such as the left cover 2-3-9) through the rotary motor base 2-3-12-1, and the other end is rotatably connected to the other side of the external pressure component frame 2-3-1 (such as the right cover 2-3-10). The rotating motor base 2-3-12-1 is started, and the rotating shaft of the rotating motor base 2-3-12-1 rotates, driving the annular rotating rod 2-3-12-3 to rotate relative to the external pressure component frame 2-3-1 to move toward or away from the lock buckle 1-6 to lock or disengage with it.

[0085] like Figure 4 , 17 As shown in Figures 18 and 18, according to one embodiment of the present invention, the rolling equipment also includes a top cover column 3 arranged in the middle of the head. A horizontal locking mechanism 2-3-11 is arranged on the external pressure component frame 2-3-1 near the top of the head. The horizontal locking mechanism 2-3-11 includes a horizontal locking motor 2-3-11-1 and a locking rod 2-3-11-2, and the locking rod 2-3-11-2 is rotatably connected to the external pressure component frame 2-3-1 through the horizontal locking motor 2-3-11-1. The horizontal locking motor 2-3-11-1 is started to drive the locking rod 2-3-11-2 to rotate horizontally close to or away from the top cover column 3, so that the locking rod 2-3-11-2 is locked or disengaged from the top cover column 3, and the external pressure component frame 2-3-1 is locked or unlocked with the top cover column 3.

[0086] In this embodiment, for example, the top cover column 3 can be provided with a groove corresponding to the locking rod 2-3-11-2 to lock the locking rod 2-3-11-2.

[0087] The above-mentioned embodiments of the present invention can be combined with each other and have corresponding technical effects.

[0088] 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.
