[0042] like Figure 1-7 As shown, this utility model provides a forming device for butt welding longitudinal seams of large plates in rocket propellant tank sections, comprising: a shaping and guiding component 3-2. The shaping and guiding component 3-2 includes an upper support component 3-2-3. The upper support component 3-2-3 includes an upper outer support component 3-2-3-1 and an upper inner support component 3-2-3-2. The upper outer support component 3-2-3-1 includes an outer guide component 3-2-3-1-3. The outer guide component 3-2-3-1-3 includes an outer arc-shaped guide plate 3-2-3-1-3-2. The upper inner support component 3-2-3-2 includes an upper inner guide component 3-2-3-2-2. The upper inner guide component 3-2-3-2-2 includes an inner arc-shaped guide plate 3-2-3-2-2-2. Each inner arc-shaped guide plate 3-2-3-2-2-2 is fitted onto the circumferential inner side of the corresponding outer arc-shaped guide plate 3-2-3-1-3-2, and the corresponding outer arc-shaped guide plates 3-2-3-1-3-2 and inner arc-shaped guide plates 3-2-3-2-2-2 are spaced apart.

[0043] The ends of the outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2 are respectively placed at the unloading port and loading port of the welding station. The outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2 are used to receive the steel plate output from the welding station, and respectively limit and guide the steel plate from both sides.

[0044] In this embodiment, the upper outer support component 3-2-3-1 and upper inner support component 3-2-3-2 of the upper support component 3-2-3 of the shaping guide component 3-2 cooperate to form a guiding and forming component, guiding and bending the steel plate. The outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2 are used to define the shape of the steel plate and guide it. This forming equipment has a simple structure and can be used in conjunction with welding and rolling equipment to weld and form short cylindrical plates. For example, the outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2 can be arc-shaped. The circumferential outer surface of the inner arc-shaped guide plate 3-2-3-2-2-2 and the circumferential inner surface of the outer arc-shaped guide plate 3-2-3-1-3-2 are profiles adapted to the tank section.

[0045] like Figure 5 and 7 As shown, according to one embodiment of the present invention, the outer arc-shaped guide plate 3-2-3-1-3-2 is provided with at least one rotatable outer rolling wheel 3-2-3-1-3-3 on its axial side. The inner arc-shaped guide plate 3-2-3-2-2-2 is provided with at least one rotatable inner rolling wheel 3-2-3-2-2-3 on its axial side. The outer rolling wheel 3-2-3-1-3-3 and the inner rolling wheel 3-2-3-2-2-3 are used to guide the steel plate.

[0046] In this embodiment, the outer rolling wheel 3-2-3-1-3-3 and the inner rolling wheel 3-2-3-2-2-3 assist the outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2 in guiding the steel plate, and convert the contact friction between the steel plate and the outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2 into rolling friction with the outer rolling wheel 3-2-3-1-3-3 and the inner rolling wheel 3-2-3-2-2-3, thereby reducing the risk of steel plate wear and uncontrollable scratches. For example, the outer rolling wheel 3-2-3-1-3-3 and the inner rolling wheel 3-2-3-2-2-3 may include rolling bearings and shafts. The shafts are locked to the outer arc-shaped guide plate 3-2-3-1-3-2 or the inner arc-shaped guide plate 3-2-3-2-2-2 by screws, and the rolling bearings are rotatable relative to the shafts. The arc length distance between two adjacent outer rolling wheels 3-2-3-1-3-3 or two adjacent inner rolling wheels 3-2-3-2-2-3 along the arc direction of the outer arc-shaped guide plate 3-2-3-1-3-2 or the inner arc-shaped guide plate 3-2-3-2-2-2 can be 300 to 700 mm. The rolling surfaces of the outer rolling wheel 3-2-3-1-3-3 and the inner rolling wheel 3-2-3-2-2-3 are 10-30 mm away from the inner arc surface of the outer arc guide plate 3-2-3-1-3-2 and the inner arc guide plate 3-2-3-2-2-2, respectively.

[0047] like Figure 5 and 7 As shown, according to one embodiment of the present invention, an outwardly inclined outwardly opening guide block 3-2-3-1-3-1 is respectively provided at both ends of the outer arc-shaped guide plate 3-2-3-1-3-2. An inwardly inclined upper inner guide block 3-2-3-2-2-1 is respectively provided at both ends of the inner arc-shaped guide plate 3-2-3-2-2-2. The outwardly opening guide block 3-2-3-1-3-1 cooperates with the corresponding upper inner guide block 3-2-3-2-2-1 to guide the steel plate to be conveyed between the outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2.

[0048] like Figure 5 As shown, in this embodiment, the extending direction of the outward-opening guide block 3-2-3-1-3-1 is not tangent to the end of the outer arc-shaped guide plate 3-2-3-1-3-2, but forms a certain angle. For example, the angle range is 3 to 20°, and its extending length ranges from 100 to 400 mm. Similarly, the upper inner guide block 3-2-3-2-2-1 is not tangent to the end of the inner arc-shaped guide plate 3-2-3-2-2-2, but forms a certain angle. For example, the angle range is 3 to 20°, and its extending length ranges from 100 to 400 mm.

[0049] like Figure 4 and 6 As shown, according to one embodiment of the present invention, in addition to the outer guide component 3-2-3-1-3, the upper outer support component 3-2-3-1 also includes an upper outer support 3-2-3-1-1. The outer guide component 3-2-3-1-3 is disposed on the upper outer support 3-2-3-1-1, and the upper outer support 3-2-3-1-1 supports the outer guide component 3-2-3-1-3. In addition to the upper inner guide component 3-2-3-2-2, the upper inner support component 3-2-3-2 also includes an upper inner support 3-2-3-2-1. The upper inner guide component 3-2-3-2-2 is disposed on the upper inner support 3-2-3-2-1, and the upper inner support 3-2-3-2-1 supports the upper inner guide component 3-2-3-2-2.

[0050] In this embodiment, for example, the upper outer support 3-2-3-1-1 can be assembled and welded from square steel. The upper outer support 3-2-3-1-1 may include a multi-layer (e.g., five-layer) semi-rectangular frame structure, such as... Figure 12As shown, a straight rod perpendicular to the opening is welded to each side of the multi-layer semi-rectangular frame structure. One end of the straight rod can be welded to a tripod. For example, the upper inner support 3-2-3-2-1 may include a central channel steel. The side of the central channel steel is provided with multiple layers of outwardly extending branches. For example, the side of the central channel steel is provided with 5 layers of outwardly extending branches, each layer including 3 branches, and the end of each layer of 3 branches away from the central channel steel is used to be fixedly connected to the inner side of an inner arc-shaped guide plate 3-2-3-2-2-2 (e.g., by welding). In addition, an additional independent support channel steel can be welded to the side of the central channel steel, and this support channel steel and the central channel steel are fixed to the upper outer support 3-2-3-1-1 (e.g., the tripod provided at the bottom of the upper outer support 3-2-3-1-1).

[0051] like Figure 2 , 8 As shown in Figure -11, according to one embodiment of the present invention, in addition to the upper support component 3-2-3, the shaping guide component 3-2 also includes a lower right support component 3-2-5 and a lower left support component 3-2-4. The lower right support component 3-2-5 includes a lower right inner guide component 3-2-5-2. The lower left support component 3-2-4 includes a lower left inner guide component 3-2-4-2. The lower right inner guide component 3-2-5-2 includes a lower right arc-shaped guide plate 3-2-5-2-2. The lower left inner guide component 3-2-4-2 includes a lower left arc-shaped guide plate 3-2-4-2-2. The lower right arc-shaped guide plate 3-2-5-2-2 and the lower left arc-shaped guide plate 3-2-4-2-2 are placed at the two ends of the outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2, respectively, and are positioned along the extension of the circumferential center line between the outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2. The lower right arc-shaped guide plate 3-2-5-2-2 is used to guide the steel plate output from the welding station to the upper support component 3-2-3. The lower left arc-shaped guide plate 3-2-4-2-2 is used to cut the steel plate output from the upper support component 3-2-3.

[0052] In this embodiment, the lower right support component 3-2-5 guides the steel plate transported from the welding station to the upper support component 3-2-3 for bending and shaping. The lower left support component 3-2-4 can transport the steel plate transported by the upper support component 3-2-3 to the rolling station for rolling. For example, the shaping guide component 3-2 may include five sets of lower right inner guide components 3-2-5-2 and lower left inner guide components 3-2-4-2. For example, the arc length of the outer arc guide plate 3-2-3-1-3-2 and the inner arc guide plate 3-2-3-2-2-2 can be less than the circumference of the corresponding equal-diameter semicircle, and the arc length of the lower right arc guide plate 3-2-5-2-2 and the lower left arc guide plate 3-2-4-2-2 can be less than 1 / 4 of the circumference of the corresponding equal-diameter circle.

[0053] The outer arc-shaped guide plate 3-2-3-1-3-2 and the inner arc-shaped guide plate 3-2-3-2-2-2, together with the lower right arc-shaped guide plate 3-2-5-2-2 and the lower left arc-shaped guide plate 3-2-4-2-2, can be combined with the rolling station and the welding station to form an almost complete circle that fits the short cylinder.

[0054] like Figure 8 and 9 As shown, according to one embodiment of the present invention, in addition to the lower left inner guide component 3-2-4-2, the lower left support component 3-2-4 also includes a lower left support 3-2-4-1. The lower left inner guide component 3-2-4-2 is disposed on the lower left support 3-2-4-1. The lower left support 3-2-4-1 is used to support the lower left inner guide component 3-2-4-2. In addition to the lower right inner guide component 3-2-5-2, the lower right support component 3-2-5 also includes a lower right frame 3-2-5-1. The lower right inner guide component 3-2-5-2 is disposed on the lower right frame 3-2-5-1. The lower right frame 3-2-5-1 is used to support the lower right inner guide component 3-2-5-2.

[0055] In this embodiment, for example, the lower right inner guide component 3-2-5-2 can be fixed to the lower right frame 3-2-5-1 by welding. The lower left inner guide component 3-2-4-2 can be fixed to the lower left bracket 3-2-4-1 by welding.

[0056] like Figure 8-11 As shown, according to one embodiment of the present invention, the lower right arc-shaped guide plate 3-2-5-2-2 is provided with at least one rotatable lower right rolling wheel 3-2-5-2-3 on its axial side. The lower left arc-shaped guide plate 3-2-4-2-2 is provided with at least one rotatable lower left rolling wheel 3-2-4-2-3 on its axial side. The lower right rolling wheel 3-2-5-2-3 and the lower left rolling wheel 3-2-4-2-3 are used to guide the steel plate.

[0057] In this embodiment, the lower right roller 3-2-5-2-3 and the lower left roller 3-2-4-2-3 can have the same or approximately the same structure and installation method as the outer roller 3-2-3-1-3-3 and the inner roller 3-2-3-2-2-3.

[0059] In this embodiment, the guide surface (i.e., the inner surface) of the lower left guide block 3-2-4-2-1 is used to guide the 6-inch steel plate. For example, the lower left guide block 3-2-4-2-1 can be approximately trapezoidal. The lower left guide block 3-2-4-2-1 can be fixedly connected to the lower left arc-shaped guide plate 3-2-4-2-2 by welding.

[0060] like Figure 1 , 2 As shown in Figure 12, according to one embodiment of the present invention, in addition to the shaping guide component 3-2, the molding equipment also includes a flipping bracket 3-1. The flipping bracket 3-1 includes a column base 3-1-3, a flipping column 3-1-4, and a C-shaped bracket 3-1-5. The flipping column 3-1-4 is disposed on the column base 3-1-3, and the C-shaped bracket 3-1-5 is disposed on the side of the flipping column 3-1-4, with the opening of the C-shaped bracket 3-1-5 away from the flipping column 3-1-4. Rotating motor components 3-2-1 are respectively disposed on the inner sides of the two opposite ends of the C-shaped bracket 3-1-5. The motor shaft of the rotating motor component 3-2-1 is connected to the shaping guide component 3-2 to flip the shaping guide component 3-2.

[0061] In this embodiment, the flipping bracket 3-1 supports the shaping guide component 3-2. The shaping guide component 3-2 guides the steel plate, transforming it from a planar state to a semi-circular cylindrical state, and then from a semi-circular cylindrical state to a circular cylindrical state suitable for forming a butt weld. After welding and rolling are completed, the forming equipment can flip the short cylinder, changing it from a horizontal to a vertical state for easy lifting. This forming equipment, in conjunction with welding and rolling equipment, can weld plates into short cylinders and then flip them for unloading. For example, the C-shaped bracket 3-1-5 and the flipping column 3-1-4 are locked together with screws.

[0062] like Figure 4 As shown, according to one embodiment of the present invention, an arc-shaped support plate 3-2-3-1-2 is provided near the end of the upper outer bracket 3-2-3-1-1. The arc-shaped support plate 3-2-3-1-2 is staggered from the outer arc-shaped guide plate 3-2-3-1-3-2. When the short cylinder formed by flipping and welding the shaping guide component 3-2 is flipped, the arc-shaped support plate 3-2-3-1-2 is used to support the short cylinder.

[0063] In this embodiment, for example, the arc-shaped support plate 3-2-3-1-2 can be an arc-shaped plate.

[0064] like Figure 2 and 13 As shown, according to one embodiment of the present invention, in addition to the upper support component 3-2-3, the lower right support component 3-2-5, and the lower left support component 3-2-4, the shaping guide component 3-2 also includes two sets of flip-connecting components 3-2-2. The flip-connecting components 3-2-2 include a connecting rod component 3-2-2-1, an upper lead screw component 3-2-2-3, and a lower lead screw component 3-2-2-2. The upper lead screw component 3-2-2-3 and the lower lead screw component 3-2-2-2 are respectively disposed on opposite sides of the connecting rod component 3-2-2-1 and are perpendicular to the connecting rod component 3-2-2-1. The two sets of flip-connecting components 3-2-2 are respectively disposed on opposite sides of the upper support component. The connecting rod component 3-2-2-1 is perpendicular to the plane containing the outer arc-shaped guide plate 3-2-3-1-3-2. The two sides of the upper outer support component 3-2-3-1 (e.g., upper outer support 3-2-3-1-1) are respectively connected to the screw slider of the upper screw component 3-2-2-3 of a set of flip-connecting components 3-2-2. The screw slider of the upper screw component 3-2-2-3 drives the upper outer support component 3-2-3-1 (e.g., upper outer support 3-2-3-1-1) to slide relative to the upper screw component 3-2-2-3. The lower right support component 3-2-5 (e.g., lower right frame 3-2-5-1) and the lower left support component 3-2-4 (e.g., lower left support 3-2-4-1) are respectively connected to the lead screw slider of the lower lead screw component 3-2-2-2 of a set of flip-connecting components 3-2-2. The lead screw slider of the lower lead screw component 3-2-2-2 drives the lower right support component 3-2-5 (e.g., lower right frame 3-2-5-1) and the lower left support component 3-2-4 (e.g., lower left support 3-2-4-1) to slide relative to the lower lead screw component 3-2-2-2.

[0065] In this embodiment, when the short cylinder is in a horizontal position, the sliders of the lower lead screw component 3-2-2-2 and the upper lead screw component 3-2-2-3 can respectively drive the lower right frame component 3-2-5, the lower left support component 3-2-4, and the upper support component 3-2-3 to move up and down, thereby controlling the distance between the lower right frame component 3-2-5, the lower left support component 3-2-4, and the upper support component 3-2-3. This allows the forming equipment to be compatible with the production of short cylinders of various diameters (e.g., compatible with various specifications of large-diameter short cylinders). For example, the lower right frame 3-2-5-1 and the lower left support 3-2-4-1 can be locked and fixed to the lower lead screw component 3-2-2-2 with screws. The upper lead screw component 3-2-2-3 and the lower lead screw component 3-2-2-2 can be linear lead screw guides. For example, along the length of the connecting rod component 3-2-2-1, multiple sets (e.g., three sets) of upper lead screw components 3-2-2-3 and lower lead screw components 3-2-2-2 can be spaced apart. The lead screw sliders of the multiple sets of upper lead screw components 3-2-2-3 move synchronously, and the lead screw sliders of the multiple sets of lower lead screw components 3-2-2-2 move synchronously to control the overall movement of the upper support component 3-2-3, the lower right frame component 3-2-5, and the lower left support component 3-2-4, respectively, so as to adapt to various specifications of large-diameter short cylinders.

[0066] like Figure 2 As shown, according to one embodiment of the present invention, the rotating motor component 3-2-1 includes a base, a motor, and an adapter plate. The base can be mounted on the C-type bracket 3-1-5 with screws. The motor can be mounted inside the base with screws. The adapter plate is welded to the end of the motor shaft. The adapter plate is fixedly connected to the connecting rod component 3-2-2-1 of the connecting component 3-2-2 of the shaping guide component 3-2 with screws. When the motor starts, it drives the motor shaft to rotate the connecting component 3-2-2, thereby causing the shaping guide component 3-2 to flip the short cylinder.

[0067] like Figure 12 As shown, according to one embodiment of the present invention, in addition to the column base 3-1-3, the flip column 3-1-4, and the C-shaped bracket 3-1-5, the flip bracket 3-1 also includes a flip base 3-1-1. The flip base 3-1-1 is provided with a flip linear guide rail 3-1-2. The column base 3-1-3 and the flip linear guide rail 3-1-2 are slidably connected to drive the shaping guide component 3-2 to move.

[0068] In this embodiment, the column base 3-1-3 slides relative to the flipping linear guide rail 3-1-2, driving the shaping guide component 3-2 to move, thereby removing the welded and rolled short cylinder from the welding or rolling station. For example, the flipping base 3-1-1 can be fixedly installed on the ground. The flipping linear guide rail 3-1-2 can be a linear guide rail with an effective stroke greater than the height of the short cylinder. For example, the column base 3-1-3 can be provided with a guide rail groove and a drive motor adapted to the flipping linear guide rail 3-1-2 to control the movement of the column base 3-1-3 along the flipping linear guide rail 3-1-2.

[0069] In this utility model, the aforementioned components, parts, or components can be connected and fixed by means of screws, riveting, welding, etc., and this utility model does not impose specific limitations on this. For example, the outer arc-shaped guide plate 3-2-3-1-3-2 is fixedly connected to the upper outer bracket 3-2-3-1-1 by welding, the lower left inner guide component 3-2-4-2 is fixedly connected to the lower left bracket 3-2-4-1 by welding, and the lower right inner guide component 3-2-5-2 is fixedly connected to the lower right frame 3-2-5-1 by welding, etc.

[0070] The above embodiments of this utility model can be combined with each other and have corresponding technical effects.

[0071] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
