The second steering seat 311 is arranged on the frame 1, and the second steering seat 311 is connected to the output end of the third motor 313. The lower end of the first screw 312 passes through the frame 1 and is connected to the second steering seat 311. The upper end of the first screw 312 is arranged in the lifting seat 32 and is threadedly matched with the lifting seat 32.

[0042] The first screw drive mechanism 31 can be configured to drive the lower die 35 below the upper die 34 to press the sheet metal product, so that the transmission device 4 drives the bending mechanism 2 to flip, thereby realizing the bending of the sheet metal product.

[0043] Each second screw drive mechanism 27 includes a third steering seat 271, a second screw 272 and a fourth motor 273. The third steering seat 271 is arranged at the bottom of the sliding arm 24.

[0047] The driving structure of the fifth motor 64 on the inner wall of the sliding arm 24 is arranged to rotate the output shaft of the fifth motor 64, and convert the rotational force into a longitudinal transmission force through the fourth steering seat 62, so as to drive the T-type screw rod 63 to rotate and at the same time drive the flip plate 21 to move forward and backward along with the second guide rail assembly 25 arranged longitudinally, so that the guide hole 213 of the flip plate 21 leaves or is sleeved on the locking column 65, so that the flip plate 21 can meet the two states of flipping and non-flipping.

[0049] Both ends of the lifting seat 32 are provided with limit seats 321 for preventing the transmission box 33 from slipping, which can effectively prevent the transmission box 33 from detaching from the lifting seat 32 to improve the safety of the planing mechanism 3.

[0050] The bending center composite machine of the present invention combines the two processes of bending and grooving, so that the two processes can be processed on the same equipment, and at the same time, the same sheet metal product can share a positioning method, and the sheet metal product can be processed without changing the positioning reference, so that the sheet metal product can be formed in the working cavity, thereby effectively improving the accuracy of grooving and bending of the sheet metal product, and also improving production efficiency.

[0051] The workflow of the present invention is:

[0052] The fifth motor 64 is started, and the lateral force of the fifth motor 64 is converted into a longitudinal transmission force through the fourth steering seat 62, which drives the rod portion of the T-type screw rod 63 to rotate, thereby driving the screw sleeve of the T-type screw rod 63 to move away from the workbench 12, and the flip plate 21 is pushed by the screw sleeve of the T-type screw rod 63 to move away from the workbench 12 on the second guide rail assembly 25. When the screw sleeve of the T-type screw rod 63 is away from the guide hole 213 on the flip plate 21;

[0053] Then, the cylinders 43 of the two transmission devices 4 extend out to drive the first steering seat 42 to rotate, so as to drive the transmission shaft 41 to rotate, and then drive the two flipping arms 22 to rotate at the same time, so as to drive the flip plate 21 and the flipping die 212 on the flip plate 21 to flip, so that the flipping die 212 is arranged horizontally, and the conveying rotating mechanism on the workbench 12 conveys the part of the sheet metal product to be bent and grooved to the working chamber, and the third motors 313 of the two first screw drive mechanisms 31 convert the horizontal force into a vertical force through the second steering seat 311, so as to drive the first screw 312 to rotate, so as to drive the lifting seat 32 Both ends slide downward on a pair of first guide rails 11 at the same time to drive the upper die pressing knife to press the sheet metal product downward onto the lower die, and then the fourth motor 273 of the two second screw drive mechanisms 27 converts the lateral force into a vertical force through the third steering seat 271 to drive the second screw 272 to rotate, thereby driving the sliding arm 24 to move away from the workbench 12 on the guide rail of the third guide rail assembly 26, and the flip plate 21 moves away from the workbench 12 under the push of the screw sleeve of the T-type screw 63, and the guide hole 21 on the flip plate 21 is no longer guided by the screw sleeve of the T-type screw 63;

[0054] When the sheet metal product needs to be reversely bent, the cylinders 43 of the two transmission devices 4 extend to drive the first steering seat 42 to rotate, so as to drive the transmission shaft 41 to rotate, thereby driving the two flip arms 22 to rotate at the same time, so as to drive the flip plate 21 to flip, and control the fourth motors 273 of the two second screw drive mechanisms 27 to start, and convert the lateral force into a vertical force through the third steering seat 271, so as to drive the second screw 272 to rotate, thereby driving the sliding arm 24 to move downward on the guide rail of the third guide rail assembly 26, and the flip plate 2 moves downward accordingly. At this time, the upper die pressing knife cooperates with the lower die to press the sheet metal product, and the flip knife mold 212 on the flip plate 2 presses against the portion of the sheet metal product close to the edge (this portion is the set reverse bending portion). At this time, the transmission device 4 flips according to the above steps, so that the flip knife mold 212 of the flip plate 2 is upward, so that the sheet metal product can achieve reverse flipping and bending;

[0055] When the sheet metal product needs to be positively bent, the flip plate 2 moves upward along the guide rail of the third guide rail assembly 26 under the drive of the two second screw drive mechanisms 27. When the flipping die 212 on the flipping plate 2 is upwardly fitted with the bottom surface of the sheet metal product near the edge (this position is the set positive bending position), the transmission device 4 drives the flipping plate 2 to rotate so that the lower part of the flipping plate 2 faces upward. During the flipping process, the flipping die 212 realizes positive bending of the sheet metal product.

[0056] After the bending is completed, the flip plate 2 is driven by the transmission device 4 to return to the original position, and the fifth motor 64 is started, and the output end of the fifth motor 64 drives the T-type screw rod 63 to move longitudinally through the fourth steering seat 62, so that the screw rod sleeve of the T-type screw rod 63 is inserted into the guide hole 213 of the flip plate 2 to complete the guiding and locking;

[0057] The forward bending part and the reverse bending part can be adjusted as needed, and after bending one wall of the sheet metal product, when the remaining walls need to be bent, the conveying and rotating mechanism on the workbench 12 will change the angle of the sheet metal product so that it can be bent in all directions of the sheet metal product.

[0058] When the sheet metal product needs to be grooved, the sixth motor 363 of the gear rack linear guide assembly 36 drives the gear to rotate, so as to drive the gear to move on the rack 362 to the working chamber. When it reaches the working chamber, the first motor 40 is started to drive the screw 30 to rotate. The sliding seat 38 moves downward on the second guide rail 37 under the thread force of the screw 30 and the screw sleeve 381, and the plurality of groove planing knives 39 installed at the lower part of the sliding seat 38 move downward accordingly to groove the sheet metal product. The installation setting The number and shape of the planing grooves are cut to meet the planing requirements. After the planing is completed, the first motor 40 is started to drive the screw rod 30 to rotate in the opposite direction. The sliding seat 38 moves upward on the second guide rail 37 under the thread force of the screw rod 30 and the screw sleeve 381, and the sixth motor 363 of the gear rack linear guide assembly 36 drives the gear to rotate, so as to drive the gear to move away from the working chamber on the rack 362 to achieve reset, which can prevent interference with the bending mechanism 2 during bending;

[0059] Bending and grooving can be performed in the order you want.
