Description

Technical Field

[0001] This invention belongs to the field of shipbuilding, and specifically relates to an auxiliary tooling and method for correcting plate edge deformation. Background Technology

[0002] like Figure 1 As shown, during the segmented construction phase, the free edges of the side plates are prone to wave deformation due to the heat stress from nearby welding and other external forces. Previously, workers used a combination of heat treatment and jacking to correct the deformation. However, this method requires the installation of auxiliary plates at the jacking location, increasing welding workload and making subsequent removal difficult, resulting in high labor intensity and limited work area. Therefore, an auxiliary force-applying fixture needs to be designed to address the issues of high labor intensity and limited work area during edge deformation correction. Summary of the Invention

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0029] The technical solution of the present invention provides an auxiliary tooling for correcting plate edge deformation, the auxiliary tooling including:

[0030] The main body of the tooling is a hollow cavity, and a detachable pushing device is installed inside the main body of the tooling.

[0031] A connecting groove is located at one end of the tooling body and is used to connect the side plate 5 and the tooling body.

[0032] like Figures 2 to 3 As shown, in one embodiment of the present invention, the tooling body includes:

[0033] Connecting plate 1 consists of two side plates of the main body of the tooling, and its front end is connected to the connecting groove.

[0034] Back plate 2 is the rear panel of the main body of the tooling, and is connected to connecting plate 1 on both sides;

[0035] Base plate 3 is located at the bottom of the tooling body;

[0036] The connecting plate 1, the back plate 2, and the bottom plate 3 constitute the frame structure.

[0037] In this embodiment, connecting plates 1 are disposed on both sides of the tooling and are used to connect the plate to be straightened and the back plate 2. The front end of connecting plate 1 is welded to U-shaped plate 4, the rear end is welded to back plate 2 (230×145×15mm), and the bottom is welded to bottom plate 3 (300×230×5mm), forming a "frame" structure. The bottom plate is welded to the bottom of the tooling and serves to support the jacking equipment.

[0038] like Figure 4 As shown, in one embodiment of the present invention, a weight-reducing hole 6 is provided in the middle of the connecting plate 1 to reduce the overall weight of the tooling.

[0039] like Figure 5 As shown, in one embodiment of the present invention, the connecting groove is a U-shaped plate 4 structure, which is disposed at both ends of the connecting plate 1.

[0040] In one embodiment of the present invention, the connecting plate 1 is welded to the U-shaped plate 4.

[0041] In one embodiment of the present invention, the connecting plate 1, the back plate 2, and the bottom plate 3 are connected by welding.

[0042] In addition to providing an auxiliary tooling for correcting edge deformation, the present invention also provides a method for correcting edge deformation using the aforementioned tooling, the method comprising the following steps:

[0043] Step 1: Clamp the opening of the connecting groove onto the edge 7 of the plate to be straightened, and place the jacking device inside the main body of the tooling to perform the jacking operation to straighten and deform the edge 7 of the plate to be straightened.

[0044] Step 2: After the correction is completed, move the connecting groove along the edge of the plate to allow the auxiliary tooling to enter the next position for correction, until all correction work is completed.

[0045] like Figure 6 As shown, in one embodiment of the present invention, the tooling is clamped onto the edge 7 of the plate to be corrected through the opening of the U-shaped plate 4. A jack is placed inside the "frame" for jacking operation. The back plate 2 and connecting plate 1, etc., have sufficient rigidity, and the bearing area of ​​the back plate 2 is larger than that of the plate edge. Under the same jacking force, the plate edge is more likely to undergo corrective deformation, such as... Figure 6 As shown in the diagram. The arrows in the diagram indicate the direction in which the jack applies force.

[0046] The fixture is not fixed when clamped to the edge of the plate by the U-shaped plate 4, and can be moved to the next position along the edge of the plate for correction. At the same time, the relative position of the fixture and the edge of the plate is fixed, which can adapt to the correction of plate edges deformed at different angles, and has a wider range of applications.

[0047] The "frame" structure composed of connecting plate 1, back plate 2, bottom plate 3 and U-shaped plate 4 provides force support for jacks and other jacking and straightening equipment, and helps to achieve deformation correction.

[0048] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
