[0035] During the process of shipbuilding, in order to eliminate bone prints or thin horses, thereby improving the appearance of the ship's outer plate, as Figures 1-4 shown, the present utility model provides a deformation correction tooling. The deformation correction tooling includes a fixed frame 1, a heating component 4, a pressing component 2 and a pressing head 3.

[0036] Among them, the fixing frame 1 includes an upper support 11 and a lower support 12 which are oppositely arranged. The upper support 11 and the lower support 12 are detachably connected, and the workpiece to be corrected is clamped between the upper support 11 and the lower support 12. The heating assembly 4 is arranged on the upper support 11 and is used to heat the position to be corrected of the workpiece to be corrected.

[0037] When processing the workpiece to be corrected, first clamp the workpiece to be corrected between the upper support 11 and the lower support 12, and then use the heating assembly 4 to heat the position to be corrected, so as to reduce the hardness of the position to be corrected and facilitate subsequent processing. Use the extrusion assembly 2 to drive the pressing head 3 to press the position to be corrected, so as to eliminate the bone print or thin horse and improve the appearance of the ship's outer plate.

[0038] In some embodiments, a magnetic attraction assembly 13 is arranged between the upper support 11 and the lower support 12. The magnetic attraction assembly 13 includes a magnet 132 and a magnetic attraction device 131.

After the correction is completed, it is convenient to quickly disassemble. In this embodiment, the magnetic attraction device 131 adopts an electromagnet. When attraction is required, the electromagnet is energized to cooperate with the magnet 132, so as to stably clamp the workpiece to be corrected. After the correction is completed, the electromagnet is powered off, and the upper support 11 and the lower support 12 can be separated.

[0039] In some embodiments, the heating assembly 4 includes a first fixing sleeve 41 and a flame cutting head 42. The first fixing sleeve 41 is fixedly arranged on the upper support 11, the flame cutting head 42 is arranged in the first fixing sleeve 41, and a first fastener is arranged on the first fixing sleeve 41. The first fastener is used to lock the flame cutting head 42. By the above method, it is convenient to install the flame cutting head 42, so as to heat-treat the position to be corrected, reduce the hardness and strength, and facilitate subsequent extrusion processing.

[0040] In some embodiments, the pressing head 3 includes an impact part and a mounting ear which are connected to each other. The mounting ear is detachably connected to the driving end of the extrusion. Through the impact part, the position to be corrected can be impacted, so as to eliminate the bone print or thin horse.

[0041] In some embodiments, the end face of the impact portion facing away from the mounting ear is an arc surface. Through the above arrangement, when impacting the position to be corrected, the impact portion is in line contact with the position to be corrected, so that the acting pressure can be increased, ensuring that the position to be corrected can be quickly extruded and processed.

[0042] In some embodiments, the extrusion assembly 2 includes a hydraulic cylinder 21, a first connecting ear, and a first locking member 221.

During use, the first connecting ear is fixed on the piston of the hydraulic cylinder 21, and then the pressing head 3 is connected to the first connecting ear by using the first locking member 221. When processing the position to be corrected, the hydraulic cylinder 21 is started, so that the piston of the hydraulic cylinder 21 extends, thereby driving the pressing head 3 to impact the position to be corrected to eliminate bone marks or thin horses.

[0043] In some embodiments, the first connecting ear includes a first sleeve and a first ear portion 22 connected to each other. The first sleeve is sleeved on the piston of the hydraulic cylinder 21.
