Thus, in the shaping process, the left side of the sheet workpiece is larger than the right side. The deformation space increases the degree of deformation of the left side of the workpiece, which is convenient for the workpiece to reach the preset flatness.

[0046] Preferably, referring to FIG. 3 and FIG. 6, in the embodiment, when the degree of warpage of the left and right sides of the sheet workpiece is greater than the degree of warpage of the middle portion, the left positioning component 318 and the right positioning component 328 respectively The second ejector unit 322 and the third ejector unit 332 are pushed up and down to be vertically separated from each other. The left support plate 319 and the right support plate 329 are arranged side by side and are parallel to the first substrate 301. The positioning form is used for fixing the position of the plate workpiece with the degree of warpage on the left and right sides greater than the degree of warpage in the middle portion. Thus, in the shaping process, the left and right sides of the sheet workpiece are respectively extended to the outside and are in a suspended state, thereby obtaining a deformation space. It is convenient for the sheet workpiece to reach the preset flatness.

The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. It will be apparent to those skilled in the art that various changes and modifications are possible. Any modifications, equivalent substitutions, improvements, etc. within the spirit and scope of the invention are intended to be included within the scope of the appended claims.
