[0023] Regarding the problems existing in the above-related technologies, such as Figure 1 As shown, a shaping device provided by an embodiment of the present invention is applied to a separator component 1. The shaping device includes a central positioning member 2, a plurality of first wing plates 3, a plurality of shaping screws 4, and support members 5 provided in one-to-one correspondence with the first wing plates 3. The plurality of first wing plates 3 are evenly distributed along the circumference of the central positioning member 2 and are symmetrically arranged with the central positioning member 2 as the center. One end of the first wing plate 3 is connected to the central positioning member 2, and the other end is connected to the support member 5. The shaping space enclosed by the central positioning member 2, the first wing plate 3, and the support member 5 is used to accommodate the separator component 1. The plurality of shaping screws 4 are respectively movably arranged on the plurality of first wing plates 3. The included angle between the moving direction of the shaping screw 4 and the axial direction of the central positioning member 2 is less than a preset angle. One end of the shaping screw 4 facing the separator component 1 is used to be connected to the separator component 1 for shaping the separator component 1.

[0024] Specifically, the shape correction device includes a central positioning member 2, a plurality of first wing plates 3, a plurality of shape correction screws 4, and a support member 5 corresponding to the first wing plates 3. Among them, the central positioning member 2 is a cylindrical structure. During shape correction, the central positioning member 2 is correspondingly arranged with the center of the separator component 1, that is, the central positioning member 2 and the separator component 1 maintain a concentric positional relationship, so that the shape correction device is located directly above the separator component 1 to complete precise positioning, thereby ensuring a uniform shape correction effect. Moreover, the central positioning member 2 provides a stable support point and can withstand the additional pressure exerted by the shape correction screws 4 when necessary. The plurality of first wing plates 3 are symmetrically arranged on the circumference of the column of the central positioning member 2, evenly distributed, and symmetrically arranged with the central positioning member 2 as the center. The number of the first wing plates 3 can be set according to the actual situation. For example, as Figure 1As shown, six first wing plates 3 are provided to evenly cover the separator component 1, facilitating the shape correction of the separator component 1. One end of the first wing plate 3 is connected to the central positioning member 2, and the other end is connected to the support member 5. The first wing plate 3 is horizontally arranged, and the support member 5 is vertically arranged. In this way, through the correspondingly connected central positioning member 2, first wing plate 3, and support member 5, a shape correction space can be enclosed to cover the separator component 1 in the shape correction space, facilitating shape correction. A plurality of shape correction screws 4 are respectively arranged on the plurality of first wing plates 3. One or more shape correction screws 4 can be arranged on each first wing plate 3, and the specific arrangement method can be set according to the actual situation. The shape correction screw 4 moves towards the separator component 1, that is, the shape correction screw 4 moves closer to the separator component 1 or moves away from the separator component 1 to correct the deformed area of the thin-walled stainless steel welding of the separator component 1, that is, to correct any thin plate welding deformation on the separator component 1. The included angle between the moving direction of the shape correction screw 4 and the axial direction of the central positioning member 2 is less than a preset angle, and the preset angle can be set according to the actual situation, with a range of 0° to 90°. During shape correction, for the convex deformed area on the surface of the separator component 1, the shape correction screw 4 can be screwed to make the shape correction screw 4 move closer to the separator component 1 to press down the convex deformed area on the surface of the separator component 1. After pressing down to the qualified level, the shape correction screw 4 is fixed and left stationary for a certain period of time to release the welding stress and ensure the shape correction effect; for the concave deformed area on the surface of the separator component 1, a shape correction screw 4 can be connected to the deformed area and fixed, and the shape correction screws 4 around it are screwed to make the shape correction screws 4 around it move closer to the separator component 1, pressing down the space around the concave deformed area, so that under the influence of the reaction force of the shape correction screws 4 around it, the operation of pulling up the concave area is realized, and it is left stationary for a certain period of time to release the welding stress and ensure the shape correction effect. Exemplarily, the stationary time is 4 to 5 hours. After the shape correction is completed, the shape correction screw 4 can be screwed in the reverse direction to release the action of the shape correction screw 4 on the separator component 1. Exemplarily, the preset angle can be set to 0°, that is, the moving direction of the shape correction screw 4 is parallel to the axial direction of the central positioning member 2.

[0025] In this embodiment, since multiple first wing plates 3 are symmetrically arranged in the circumferential direction of the central positioning member 2, and one end of the first wing plate 3 is connected to the central positioning member 2 and the other end is connected to the support member 5, a sizing space can be formed by the central positioning member 2, multiple first wing plates 3 and the corresponding support members 5 for the support member 5, and the separator component 1 is entirely accommodated in the sizing space for sizing. Then, through the sizing screws 4 installed on different first wing plates 3, any deformed part on the separator component 1 can be sized, thereby improving the dimensional accuracy of the separator component 1, increasing the qualified rate of manufacturing the separator component 1, and further improving the manufacturing efficiency of the separator component 1. Moreover, the sizing device of the present invention has a simple structure and is easy to operate, which can greatly reduce the sizing cost.

[0026] Optionally, the sizing screw 4 includes a nut 41 and a screw body 42. The screw body 42 is arranged in the nut 41. The nut 41 is installed on the first wing plate 3, and the threaded hole of the nut 41 faces the separator component 1. The sizing device further includes at least one pulling member 6. One end of the pulling member 6 is connected to the extension plate 7 of the nut 41, and the other end is used to be connected to the separator component 1.

[0027] Specifically, as Figure 1 and Figure 2 shown, the sizing screw 4 includes a nut 41 and a screw body 42. The screw body 42 is arranged in the nut 41. The nut 41 is installed on the first wing plate 3, and the threaded hole of the nut 41 faces the separator component 1. And the screw body 42 is provided with an external thread corresponding to the threaded hole, so that the screw body 42 moves closer to or away from the separator component 1. The sizing device further includes at least one pulling member 6. The pulling member 6 is in an "L" shape. At least one pulling member 6 can be respectively arranged on different nuts 41 according to actual situations to meet different sizing requirements. One end of the pulling member 6 is connected to the extension plate 7 of the nut 41, and the other end is used to be connected to the separator component 1 to facilitate sizing the concave deformed area on the surface of the separator component 1. During sizing, the other end of the pulling member 6 is connected and fixed to the concave part of the separator component 1. The screw body 42 near the pulling member 6 is rotated to make the screw body 42 near the pulling member 6 move closer to the separator component 1, pressing down the space around the concave part, so that under the influence of the reaction force of the nearby sizing screw 4, the pulling member 6 realizes the operation of pulling up the concave deformed area and stays still for a certain time to release the welding stress and ensure the sizing effect.

[0028] Optionally, the sizing device further includes an extension plate 7. The extension plate 7 is arranged on the nut 41 and extends radially outward along the nut 41. One end of the pulling member 6 is connected to the extension plate 7, and the other end is used to be connected to the separator component 1.

[0029] Specifically, as Figure 2 shown, the shape correction device further includes an extension plate 7. The extension plate 7 is in an "L" shape and is arranged on the nut 41 and extends radially outward along the nut 41. One end of the upward pulling member 6 is connected to the extension plate 7. On the one hand, it can increase the angle at which the upward pulling member 6 can be connected to the separator component 1, thereby increasing the applicability. On the other hand, the connection between the upward pulling member 6 and the extension plate 7 is more firm, which can prevent the upward pulling member 6 from falling off the nut 41 to ensure the smooth progress of shape correction and increase the manufacturing efficiency of the separator component 1.

[0030] Exemplarily, arranging the upward pulling member 6 or the extension plate 7 on the nut 41 has higher practicality and applicability compared to arranging the upward pulling member 6 or the extension plate 7 on the screw body 42. Since the screw body 42 is threadedly connected to the nut 41, whether the screw body 42 moves away from or approaches the separator component 1, the screw body 42 needs to rotate itself to achieve movement. If the upward pulling member 6 or the extension plate 7 is arranged on the screw body 42, the upward pulling member 6 or the extension plate 7 will also rotate with the rotation of the screw body 42, making it difficult to fix to the separator component 1 and unable to perform the upward pulling or downward pressing operation. In addition, the screw body 42 is slidably arranged relative to the first wing plate 3, and the threaded connection can ensure the stability of the shape correction process. For example, it can ensure that the screw body 42 stays at the position of the depression for a preset time when acting on the depression to ensure the full release of the welding stress and thus improve the shape correction effect.

[0031] Optionally, adjacent two of the first wing plates 3 are connected by a second wing plate 8, and a plurality of the shape correction screws 4 are respectively movably arranged on a plurality of the first wing plates 3 and / or the second wing plate 8.

[0032] Specifically, as Figure 2 shown, a second wing plate 8 is further provided between adjacent two of the first wing plates 3. Adjacent two of the first wing plates 3 are connected by the second wing plate 8, and a plurality of the shape correction screws 4 are respectively arranged on a plurality of the first wing plates 3 and / or the second wing plate 8. The second wing plate 8 arranged between adjacent two of the first wing plates 3 can not only increase the shape correction range but also ensure the rigidity and stability of the shape correction device. The shape correction screw 4 can be arranged on the first wing plate 3 or the second wing plate 8, and the number of arrangements is not limited and can be set according to the actual situation to meet different shape correction requirements. Exemplarily, 6 first wing plates 3 and 6 second wing plates 8 can be arranged. The 6 second wing plates 8 can enclose a hexagon. One shape correction screw 4 can be arranged on each first wing plate 3, and 3 shape correction screws 4 can be arranged on each second wing plate 8. Such an arrangement can make the shape correction screws 4 cover the entire welding deformation area of the separator component 1, meet different shape correction requirements, and at the same time make the structure of the shape correction device more stable.

[0033] Optionally, a spacer 9 is further provided between the shape correction screw 4 and the separator component 1.

[0034] Specifically, as Figure 2 shown, a spacer block 9 is further provided between the sizing screw 4 and the separator component 1. The number of spacer blocks 9 can be set according to the actual situation. One or more spacer blocks 9 are stacked in sequence between the sizing screw 4 and the separator component 1 to increase the length that the sizing screw 4 can be pressed down, so as to meet different sizing requirements and different sizes of separator components.

[0035] Optionally, the support member 5 includes a support plate 51 and a bottom plate 52. The bottom plate 52 is horizontally laid, the support plate 51 is vertically arranged, and one end of the support plate 51 is connected to the first wing plate 3, and the other end is connected to the bottom plate 52.

[0036] Specifically, as Figure 1 and Figure 2 shown, the support member 5 includes a support plate 51 and a bottom plate 52. The bottom plate 52 is horizontally laid on the sizing steel platform, the support plate 51 is vertically arranged, and one end of the support plate 51 is connected to the first wing plate 3, and the other end is connected to the bottom plate 52 to support the sizing device and form a sizing space.

[0037] Optionally, a reinforcing member 10 is provided at the connection between the first wing plate 3 and the support member 5.

[0038] Specifically, as Figure 2 shown, a reinforcing member 10 is provided at the connection between the first wing plate 3 and the support member 5 to enhance the stability between the first wing plate 3 and the support member 5.

[0039] Optionally, the reinforcing member 10 includes a backing plate 101 and a rib plate 102. The backing plate 101 is arranged at a position on the first wing plate 3 close to the support member 5, and one end of the rib plate 102 is connected to the backing plate 101, and the other end is connected to the support member 5.

[0040] Specifically, as Figure 2 shown, the reinforcing member 10 includes a backing plate 101 and a rib plate 102. The backing plate 101 is arranged at a position on the first wing plate 3 close to the support member 5 to make the backing plate 101 and the support member 5 in the same plane, that is, to make both ends of the rib plate 102 in the same plane. In this way, one end of the rib plate 102 is connected to the backing plate 101, and the other end is connected to the support member 5 which is in the same plane as the backing plate 101, which can increase the stabilizing effect.

[0041] Optionally, a reinforcing rib is provided at the connection between the support plate 51 and the bottom plate 52.

[0042] Specifically, a reinforcing rib is provided at the connection between the support plate 51 and the bottom plate 52 to increase the stability between the support plate 51 and the bottom plate 52.

[0043] Optionally, the shape correction device further includes a locking screw. A locking threaded hole corresponding to the locking screw is provided on the side wall of the nut 41, and the locking screw passes through the locking threaded hole and abuts against the side surface of the screw body 42.

[0044] Specifically, the shape correction device further includes a locking screw. The locking screw is provided with an external thread, and a locking threaded hole corresponding to the locking screw is provided on the side wall of the nut 41. The locking threaded hole is provided with a corresponding internal thread. When the screw body 42 is screwed to the corresponding position and needs to be stationary, the locking screw is screwed so that the locking screw passes through the locking threaded hole and abuts against the side surface of the screw body 42, thereby fixing the screw body 42.
