[0050] In some specific embodiments, the first adjusting structure 230 comprises a sliding block 232 capable of sliding in the first direction, and the sliding block 232 is capable of rebounding, so that the sliding block 232 can be automatically reset to enable repeated and continuous edge covering operation; the flattening member 231 is arranged on the sliding block 232, that is, the flattening member 231 can slide in the first direction together with the sliding block 232.

[0051] Specifically, the sliding of the sliding block 232 is realized by a guide rod, the rebounding of the sliding block 232 is realized by a spring or a spring piece structure, the sliding block 232 is sleeved on the guide rod, the guide rod is fixed on the second adjusting structure, the guide rod is provided with limiting blocks at both ends, and the spring is sleeved on the guide rod and located at the side away from the limiting member 202 of the sliding block 232.

[0052] In some embodiments, the second adjusting structure comprises a floating block 250 capable of sliding in the second direction, the floating block 250 is arranged to be resilient so as to automatically return to the original position after the edge covering is completed, facilitating repeated and continuous edge covering operation; the first adjusting structure 230 is arranged on the floating block 250, that is, the first adjusting structure 230 can follow the floating block 250 to float up and down for adjusting.

[0053] In some specific embodiments, the edge covering die further comprises a lower die base 201 and a positioning member 202, the positioning member 202 and the edge covering assembly are arranged on the lower die base 201.

[0054] In the embodiment, the spring is selected as the resilient member 260. The guide shaft 270 is fixed on the lower die base 201, the floating block 250 is provided with a guide hole matched with the guide shaft 270, and the spring is arranged between the floating block 250 and the lower die base 201.

[0055] In some embodiments, the edge covering assembly further comprises a knife 210 and a block 220, the knife 210 and the block 220 are configured to move synchronously in the same direction, in the embodiment, the knife 210 and the block 220 are arranged on the upper die base, the upper die base can move towards the lower die base 201 to close the die, and the lower die base 201 is further provided with a knife stopper 280 matched with the knife 210.

[0056] In the movement process of the knife 210 and the block 220, the knife 210 first abuts against the sliding block 232 to drive the sliding block 232 to move towards the guide groove, so as to drive the ear portion 121 to be inclined and bent towards the middle column of the door frame, and the block 220 abuts against the sliding block 232 or the flattening member 231 after the ear portion 121 is inclined, so as to drive the flattening member 231 to push the ear portion 121 in the second direction, thereby driving the ear portion 121 to complete the edge covering operation by abutting against the guide groove.

[0057] In some embodiments, as shown in Figure 8 and Figure 9 the movement direction of the knife 210 is parallel to the second direction, that is, the movement direction of the knife 210 is a vertical direction, and the sliding block 232 is driven by the knife 210 through a wedge structure. The vertical movement of the knife 210 is converted into the horizontal movement of the sliding block 232 or the flattening member 231 by the wedge structure.

[0058] Specifically, the first inclined surface 211 is arranged on the knife 210, the second inclined surface 233 is arranged on the sliding block 232, and the first inclined surface 211 is parallel to the second inclined surface 233. In the closing process of the upper die base and the lower die base 201, as shown in Figures 8 to 12As shown, the first inclined surface 211 on the insert 210 cooperates with the second inclined surface 233 of the sliding block 232, so that the flattening piece 231 moves along the horizontal direction towards the guide groove following the sliding block 232. During the process from contact to disengagement of the first inclined surface 211 and the second inclined surface 233, the flattening piece pushes the ear portion 121 to incline towards the inside of the door frame column. When the first inclined surface 211 and the second inclined surface 233 disengage, the flattening piece 231 stops moving along the first direction. When the upper die holder and the lower die holder 201 continue to close, the block 220 contacts the sliding block 232 or the flattening piece 231 and drives the flattening piece 231 to move along the vertical direction, so that the flattening piece 231 can be Figure 11 and Figure 12 As shown, the ear portion 121 is pressed to fit and cover the guide groove, so that the inner edge covering operation is completed.
