[0082] like Figures 2 to 5As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the internal support mechanism 2 includes an internal lifting body 201, which can be lifted and lowered in the punching machine frame 101; a main support unit, which is installed on the top of the internal lifting body 201, and has a pair of internal flip grooves 202 and a pair of internal flip support plates 203 that are mutually connected by a linkage 5; an auxiliary support unit, which is movably installed on the bottom of the internal lifting body 201, and has a pair of telescopic grooves 204, a pair of telescopic support plates 205 and a pair of transmission members 6, and the pair of transmission members 6 is used to make each internal flip support plate 203 and each telescopic support plate 205 synchronously extend / retract the inner flip groove 202 and the telescopic groove 204.

[0083] Furthermore, the linkage member 5 includes a lifting groove 501, which is arranged at the top of the inner lifting body 201 and is connected to a pair of inner flip grooves 202; a pair of rotating sleeves 502, which are rotatably installed at the top of each inner flip groove 202 through corresponding rotating shafts; a lifting linkage block 503, which can be lifted and installed in the lifting groove 501, and racks are arranged on both sides; a pair of transmission tooth groups 504, which are respectively fixedly arranged on each rotating sleeve 502, and are respectively engaged with the corresponding racks for transmission, and the upper ends of each inner flip support plate 203 are respectively fixedly connected to the corresponding rotating sleeve 502.

[0084] Furthermore, the linkage member 5 also includes a reset groove 505, which is arranged at the lower end of the lifting linkage block 503; a support block 506, which is fixedly installed at the inner end of the lifting groove 501; and a reset spring 507, which is arranged between the inner end of the reset groove 505 and the upper end of the support block 506, and always maintains a compressed state.

[0085] Furthermore, the transmission member 6 includes a connecting groove 601, which includes a vertical portion 6011 connected to the lower end of the inner flip groove 202, and a horizontal portion 6012 connecting the vertical portion 6011 and the telescopic groove 204; a floating block 602, which can be lifted and installed in the connecting groove 601, and the upper end is inclined on the inner side; a transverse groove 603, which is arranged at the lower end of the floating block 602, and has a transmission arc groove 605 on the opposite inner wall; a connecting block 604, one end of which is fixedly connected to the telescopic support plate 205, and the other end passes through the horizontal portion 6012 and extends into the transverse groove 603; a pair of transmission blocks 606, which can slide in the corresponding transmission arc grooves 605 respectively, and are fixedly connected to the connecting block 604, and the spacing between the upper ends of the pair of transmission arc grooves 605 is greater than the spacing between their lower ends.

[0086] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the inner lifting body 201 rises / falls under the drive of the joint actuating mechanism 4;

[0087] During the rising process of the inner lifting body 201, it extends into the door frame product, and the lifting linkage block 503 first contacts the top inner wall of the door frame product. As the inner lifting body 201 continues to rise, the lifting linkage block 503 descends in the lifting groove 501, and the racks on both sides thereof descend accordingly, cooperating with a pair of transmission tooth groups 504, driving a pair of rotating shaft sleeves 502 to rotate around the corresponding rotating shaft, and the lower end of each inner flip support plate 203 flips outward toward the corresponding inner flip groove 202. At the same time, the lower end of each inner flip support plate 203 contacts and cooperates with the inclined part of the upper end of the corresponding floating block 602, pushing the corresponding floating block 602 to slide to the bottom of the vertical portion 6011, and the corresponding transmission arc groove 605 descends with the floating block 602 , each transmission block 606 slides toward the upper end of the corresponding transmission arc groove 605, so that a pair of connecting blocks 604 and the corresponding telescopic support plate 205 slide outward of the telescopic groove 204, and the return spring 1 507 is compressed and shortened in this process. At the same time, a return spring 2 607 is provided between the floating block 602 and the lower end of the vertical portion 6011, and the return spring 2 607 is also compressed and shortened. This process continues until the top surface of the inner lifting body 201 and the top surface of the lifting linkage block 503 are in contact with the top inner wall of the door frame product at the same time. At this time, the outer wall of each inner flip support plate 203 is pressed against the inner wall of the door frame product, and the outer wall of each telescopic support plate 205 is pressed against the inner wall of the door frame product, so as to achieve support and limit of the inner wall of the door frame product;

[0088] During the descent of the inner lifting body 201, it moves downward to the door frame product, and its top surface is separated from the inner wall at the top of the door frame product. Under the action of the reset spring 507, the lifting linkage block 503 rises in the lifting groove 501, and the corresponding rack cooperates with a pair of transmission tooth groups 504, causing a pair of like rotating shaft sleeves to rotate around the corresponding rotating shaft, so that the corresponding inner flip support plate 203 moves into the inner flip groove 202 and breaks away from the contact with the inner wall of the door frame product. When the lower end of each inner flip support plate 203 breaks away from the contact with the upper end of the corresponding floating block 602, the floating block 602 rises in the corresponding vertical portion 6011, and each transmission block 606 slides toward the lower end of the corresponding transmission arc groove 605. At the same time, it drives each telescopic support plate 205 to retract into the corresponding telescopic groove 204 through the corresponding connecting block 604, thereby releasing the support for the inner wall of the door frame product.

[0089] Embodiment 3:

[0090] like Figures 2 to 5As shown, in the present embodiment, in addition to the structural features of the aforementioned embodiments, the external support mechanism 3 includes a pair of external lifting bodies 301, each including a lifting part and a boss 302 extending toward the inner lifting body 201; a pair of external grooves 303, each arranged on the side wall of each lifting part facing the inner lifting body 201, with the upper end extending to the lower side of the corresponding boss 302; a pair of external flip support plates 304, the upper ends of which are rotatably mounted on the middle and lower parts of the corresponding outer grooves 303 through corresponding rotating shafts; a pair of flip plates 305, the inner ends of which are rotatably mounted on the upper ends of the corresponding outer grooves 303 through corresponding rotating shafts, and the outer ends extend to the bottom of the boss 302; a pair of transmission gear sets, used to make the inner ends of the flip plates 305 transmission-connected with the corresponding outer flip support plates 304, so that each flip plate 305 and the outer flip support plate 304 can synchronously extend out of the outer groove 303 / retract into the outer groove 303.

[0091] Furthermore, the transmission gear set includes a first gear 306, which is fixedly mounted on the inner end of the flip plate 305; a second gear 307, which is rotatably mounted on the outer side of the middle part of the outer groove 303; and a third gear 308, which is fixedly mounted on the upper end of the outer flip support plate 304, and the first gear 306 and the third gear 308 are connected through the second gear 307.

[0092] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the outer side of the lower end of the door frame product usually has an outer convex structure to ensure strength, and the outer supporting structure utilizes the structure of the door frame product. The inner lifting body 201 is driven by the joint actuating mechanism 4 to descend / ascend;

[0093] When the outer lifting body 301 descends, the outer ends of a pair of flip plates 305 first contact the outer convex structure of the door frame product, and as the outer lifting body 301 continues to descend, the inner ends of the pair of outer flip plates 305 rotate around the corresponding rotating shafts, and the upper ends of the outer flip support plates 304 are driven to rotate around the corresponding rotating shafts through the first gear 306, the second gear 307 and the third gear 308, and the outer flip support plates 304 approach the outer wall of the door frame product until the top surface of the flip plate 305 is tightly pressed against the top of the corresponding outer groove 303, and the bottom surface and the lower surface of the boss 302 are located in the same plane, and both are in contact with the outer convex structure of the door frame product. At this time, the outer wall of the corresponding outer flip support plate 304 is in contact with the lower part of the outer wall of the door frame product, supporting and positioning the open end side wall of the door frame product that is easily deformed;

[0094] A return spring 309 is provided between the flip plate 305 and the top of the outer groove 303. When the outer end of the flip plate 305 enters the top of the outer groove 303, the return spring 309 is compressed and shortened to store elastic potential energy.

[0095] When the outer lifting body 301 rises, the boss 302 moves away from the outer convex structure of the door frame, and the reset spring 309 releases its elastic potential energy, pushing the outer end of the flip plate 305 to move outside the top of the outer groove 303. The inner end of the flip plate 305 rotates around the corresponding rotating shaft, and the corresponding outer flip support plate 304 is driven to rotate around the corresponding rotating shaft through the first gear 306, the second gear 307 and the third gear 308, so that each outer flip support plate 304 is out of contact with the outer wall of the door frame product, thereby releasing the support for the outer wall of the door frame product.

[0101] The motor 405 drives the output gear 404 to rotate, and drives the pair of sliding blocks 403 to approach each other in the slide groove 402 through a pair of corresponding racks. The upright portions 7061 and the bent portions 7062 of the plurality of connecting rods 706 rotate around the corresponding rotating shafts, and push an inner lifting body 201 to rise, until the upright portions 7061 of each connecting rod 706 rotate to a vertical state. At this time, a side wall of the upright portion 7061 abuts against a side wall of the corresponding groove 701 and cannot continue to rotate. The pair of sliding blocks 403 are still close to each other. In this process, the pressing slider 704 slides toward the outer end of the pressing groove, the preload spring 705 is compressed and shortened, and the adjacent ends are extended between the bottom of the inner lifting block and the sliding groove 402, and abut against the bottom end of the inner lifting block. At the same time, each transmission groove 802 moves with the corresponding sliding block, so that the corresponding transmission slider 803 passes from the upper transverse groove 8021 through the inclined groove 8022 and enters the corresponding lower transverse groove 8023. In this process, the outer lifting body 301 descends;

[0102] The motor 405 drives the output gear 404 to rotate, and drives a pair of sliding blocks 403 to move away from each other in the sliding groove 402 through a pair of corresponding racks. Each preload spring 705 releases its elastic potential energy, causing the corresponding clamping slider 704 to slide to the other end of the corresponding clamping groove. During this process, the inner end of each sliding block 403 withdraws from the bottom of the inner lifting body 201. As the sliding block 403 continues to move, the upright portion 7061 and the bent portion 7062 of each connecting support rod 706 rotate around the corresponding rotating shaft, and the upright portion 7061 descends, causing the inner lifting body 201 to descend. At the same time, each transmission slider 803 enters the corresponding upper horizontal groove 8021 from the corresponding lower horizontal groove 8023 through the inclined groove 8022, driving the outer lifting body 301 to rise.
