When the piston rod is operated to the maximum stroke, the working surface of the piston rod end block of the double-rod cylinder positioning assembly 411 is located at the second direction end of the preset door pocket plate; the working surface of the block is spaced apart from the running track of the head script body 2111.

[0120] Step 2) simultaneously start the seventh driving device 315 of the positioning platform 31, so that the positioning platform 31 moves horizontally along the second direction of the sizing guide frame 12 to a preset position, and the seventh driving device stops running at this time. The vertical distance between the running track of the sizing body 3211 and the running track of the head trimming body 2111 is the preset length of the door sleeve plate 5;

[0121] Step 3) place the door sleeve plate 5 on the workbench 111 and the moving platform 31, so that the clamping groove 51 of the bottom surface of the door sleeve plate 5 is inlaid and clamped with the first clamping position 112 and the second clamping position 311, and the inner edge of the clamping groove 51 is inlaid with the inner edge of the first clamping position 112 and the second clamping position 311, adjust the door sleeve plate 5 so that the first edge in the second direction abuts against the pressing block of the double-rod pneumatic cylinder positioning assembly 411;

[0122] Step 4) simultaneously start the pressing device 42, so that the door sleeve plate 5 is pressed and fixed on the workbench 111 and the positioning platform 31;

[0123] Step 5) start the head trimming device 21 and the sizing cutting device 32, and simultaneously make the piston rod of the positioning device 41 return to the original position, so as to complete the head trimming and sizing cutting of the door sleeve plate 5. After the above operation is completed, the head trimming device 21 and the sizing cutting device 32 are lifted upward, so that the cutting tool is away from the door sleeve plate 5, and the first direction is horizontally returned to the original position;

[0124] Step 6) start the slotting device, and the slotting body 2211 and the line marking body 2221 move along the first direction of the operation table 11 to perform the slotting and trimming operation on the bottom surface of the door sleeve plate 5. After the above operation is completed, the slotting body 2211 and the line marking body 2221 are horizontally returned to the original position along the first direction;

[0125] Step 7) start the pressing device 42, so that the piston rod returns to the original position, and the pressing and fixing of the door sleeve plate 5 are released;

[0126] Step 8) start the single-rod pneumatic cylinder positioning assembly 412 of the positioning device 41, and the piston rod extends to the maximum stroke. When the piston rod end of the single-rod pneumatic cylinder positioning assembly 412 abuts against the pressing block, the pressing block pushes the door sleeve plate 5 along the second direction, and the door sleeve plate is taken off;

[0127] Step 9) start the seventh driving device 315 of the moving platform 31, so that the moving platform 31 is horizontally returned to the original position along the second direction;

[0128] Step 10) repeat the above steps 1) to 9) to perform the next operation.
