Description

Technical Field

[0001] The utility model relates to the technical field of shell shape correction, in particular to a thin-wall shell shape correction device. Background Art

[0002] After the semi-finishing process, the thin-walled shell needs to be shaped according to the wall thickness. During the shaping process, if the shaping force is not properly controlled, the shell will be over-shaped. After the subsequent finishing of the outer circle, the shaped parts often have different degrees of "sag". This phenomenon not only affects the appearance of the product, but also affects the product's use function, especially the metal shell, which is squeezed by external force during the processing and is easy to deform. Therefore, a shaping device is needed to assist in the correction of the shell.

The utility model has a simple structure, and the distance between the first supporting shaft and the second supporting shaft can be adjusted at any time, and metal cylinders of different diameters can be calibrated.

[0035] The working principle of the thin-walled shell shape correction device is described in detail below.

[0036] like Figure 1-5 As shown, when using the thin-walled shell correction device, first, the metal thin-walled shell to be corrected is passed between the limiting roller 47 and the correction component 34, and then the hydraulic cylinder 1 21 is started, and the telescopic limiting rod 1 22 is cooperated to drive the support roller 23 to rise, so as to assist in supporting the metal thin-walled shell, and the height of the support roller 23 is adjusted according to the position of the shell.

Thereby, the limiting slide bar 35 is cooperated to drive the correction component 34 to move in the horizontal direction, and the correction component 34 is moved to one end of the metal thin-walled shell, and then the slow-speed motor 345 is started to drive the correction wheel 1 346 to rotate and the belt drives the correction wheel 2 347 to rotate synchronously, so as to correct the outer surface of the metal thin-walled shell. During the correction process, the driving motor 31 is cooperated to drive the correction component 34 to move in the horizontal direction, so that the metal thin-walled shell can be corrected in all directions. Before the metal thin-walled shell is corrected, the fixing bolt 45 is rotated to make the connecting wheel 43 slide freely inside the support plate 42, so as to adjust the position of the rotating roller 44, so that the rotating roller 44 contacts the outer surface of the metal thin-walled shell, thereby assisting the metal thin-walled shell to be limited during the rotation correction process.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
