a plurality of puzzle modules 22 are removed in sequence.

Illustratively, the order in which the plurality of tile modules are removed is as follows: the first side module 225 and the second side module 226 are moved toward the center module 21 and then removed, and the first module 221, the second module 222, the third module 223 and the fourth module 224 are moved toward the first side module 225/the second side module 226-center module 21.

Illustratively, when the frame 60 is formed, the demolding operation is performed in step S400, and referring to fig. 8 to 10, the pressing mold 40 is removed, and the first mold 10 and the central module 21 are simultaneously removed, so that the puzzle modules 22 can be sequentially removed due to the limited size of the puzzle modules 22 and the removal of the central module 21; as shown in fig. 11a and 11b, the first edge module 225 may be moved downward and taken out, and similarly, the second edge module 226 may be moved upward and taken out; as shown in fig. 12a and 12b, the first module 221 is moved to the left for extraction, and similarly, the third module 223 is moved to the left for extraction; as shown in fig. 13a and 13b, the fourth module 224 is moved to the right for removal, and similarly, the second module 222 is moved to the right for removal; all of the puzzle modules 22 have been removed to this point.

For example, in the press forming process, the occupied area of the first mold 10 may be smaller than the inner frame area of the hemming frame 60, so that the excess metal sheet 30 may be press-filled by the press mold 40 and then simply ground according to the actual size requirement.

For example, the groove wall of the bottom mold 50 has a shape corresponding to the envelope of the frame 60, for example, the envelope is a right angle, the groove wall may be a square, if the envelope is a circle, the groove wall may be a quarter circle, and the position of the die 40 corresponding to the envelope may be protruded to form another quarter circle, so that the envelope may have a semicircular shape.

Similarly, when the pressing mold 40 and the bottom mold 50 are both right-angled, they may be polished by polishing to form a rounded outer frame (i.e., a semicircular envelope shape).

Illustratively, the embodiment of the application also provides a hemming frame, and the hemming frame is prepared by using the hemming die shown in fig. 4.

In some embodiments, the hemmed outer shell is made by a method of removing grinding material, for example, a square aluminum outer shell with a size of 20cm x 10cm and a 2cm hemmed outer shell with a size of 20cm x 10cm and an inner shell with a size of 16cm x 6cm is made by a method of forming a hollow structure in a rectangular aluminum block by first hollowing out a 16cm x 6cm inner shell area by laser, UV photo etching, etc., and then grinding the corresponding area of the hemmed outer shell to form the hemmed outer shell. In the manufacturing process, due to the fact that a hollow structure needs to be formed, most materials of the aluminum block are removed, a large amount of resources are wasted, the manufacturing process at least needs to be etched, edge covering and polishing are carried out, and the steps are complex. The existing production process of the edge-wrapping shell causes a large amount of material waste and complicated production process.

The edge covering die, the using method and the edge covering frame provided by the embodiment of the application can be used for specially producing the edge covering frame 60, and the edge covering die can be taken out in sequence after the edge covering frame 60 is formed, so that the technical effects of simplifying the manufacturing process and reducing material waste are achieved.
