The whole flow of the invention is as follows:
1. firstly, the flange is placed on a lifting table of the feeding device, the lifting table is driven to ascend by a motor, and after the flange ascends to a certain height, the lifting table drives the flange to ascend to the first automatic feeding mechanism 20.
2. When the conveying device 50 drives the flange to move to the material supporting platform 233 of the lifting material supporting device 23 on the first automatic feeding mechanism 20 and is stopped by the cylindrical positioning rod 2341 positioned between the material supporting conveying roller ways, the control system controls the conveying roller ways to stop conveying operation, then controls the piston rods of the lifting cylinders 2313 of the lifting material supporting device 23 to extend out, drives the material supporting conveying roller ways to lift to the material pushing height position of the telescopic material pushing device 24, and then controls the material pushing cylinders 2423 of the telescopic material pushing device 24 to move, so that the flange end plate is pushed out from the material supporting conveying roller way to the processing station of the lathe device 10.
3. After the flange is machined on the lathe device 10, the chuck loosens the flange, the pushing cylinder 2423 pushes the flange out of the chuck, and the conveying device 50 continues to drive the flange to move forwards.
3. The flange is then moved onto the pallet 233 of the lifting pallet 23 on the second automatic feeding mechanism 25 in a manner consistent with the first automatic feeding mechanism, and is then pushed out from the pallet conveyor table position onto the processing station of the first punch press device 30.
4. When the flange is placed on the positioning plate 3411 in the positioning device 341 in the first punching device 30, the guide rod 3416 moves vertically downward along the guide sleeve 3415 under the driving of the lifting cylinder 3417, so as to drive the positioning plate 3411 to descend. After the positioning plate 3411 contacts the upper surface of the fixing plate 3415, the positioning block 3413 protrudes from the positioning hole 3412 to position the flange. In the process of lowering the positioning plate 3411, the flange is driven to descend together, and finally the flange is placed on the supporting portion 34321 of the rotating plate 3432 of the rotary tensioning device 343, and at this time, the clamping head 3431 passes through the through hole of the flange and is located at the upper end of the flange. The platen lock 345 is then actuated and the platen 3454 is moved horizontally over the flange by the push cylinder 34511 in the push actuator 3451, with the collet 3431 now just falling within the cavity of the platen 3454. Under the driving of the lifting air cylinder 34524 in the lifting transmission mechanism 3452, the guide pillar 34523 moves downwards along the guide sleeve 34522, so that the pressure plate cover plate 3453 is driven to downwards press the pressure plate 3454, and then under the driving of the rotating device 3435 in the rotating tensioning device 343, the chuck 3431 is driven to downwards press, so that the pressure plate 3454 is driven to press and lock the workpiece. The flange is securely locked to the press tooling station by the cooperation of the swivel tensioner 343 and the platen lock 345.
5. And then the punching head 33 of the punching machine punches the flange, and the indexing device 3433 in the rotary tensioning device 343 drives the transmission device 3434 to drive the turntable 3432 to rotate by a certain angle to drive the part of the flange, which is not punched, to rotate to the processing area of the punching head 33 so as to complete the next punching period of the punching head 33 in a matching way. In the punching process, the punching force is transmitted to the piston rod of the buffer cylinder 3421 through the buffer plate 3422 in the buffer device 342, the piston rod is compressed and retreated under the action of the punching force, the initial punching force of the punch 33 is unloaded to a certain extent, the punch 33 is prevented from rigidly contacting with the flange during punching, and the service life of the punch 33 is prolonged. After the punching is completed, under the driving of the turning device 3435, the chuck 3431 is lifted upwards, then the lifting cylinder 34524 pushes the platen cover plate 3453 to lift, the pushing transmission mechanism 3451 drives the platen 3454 to retract, the positioning plate 3411 is lifted under the driving of the lifting cylinder 3417, and meanwhile, the flange is driven to return to the position before the punching, then the pushing cylinder 2423 of the telescopic pushing device 24 pushes the unprocessed flange to the positioning plate 3411 in the first punching device 30, and the punched flange is pushed to the conveying device 50 to continue to advance.
6. When the flange is at the feeding end of the drilling and tapping machine 40, under the control of the control device 46, the oil cylinder 4511 in the automatic material taking mechanism 45 drives the sliding block 4512 to move along the guide rail 4513, the first vertical moving device 452 is driven to move to the feeding station of the flange feeding end, the second vertical moving device 457 is driven to move to the machining station of the flange drilling and tapping machine, the control device 46 controls the air cylinders 4523 in the first vertical moving device 452 and the second vertical moving device 457 to act, the first material taking device 453 and the second material taking device 458 move downwards to the flange, the electromagnet 4531 is electrified to generate magnetic force, after the flanges on the two stations are respectively absorbed, the control device 46 controls the oil cylinder 4511 to drive the sliding block 4512 to move reversely along the guide rail 4513, the first vertical moving device 452 and the second vertical moving device 457 are driven to be right above the next station along the guide rail 4513, the electromagnet 4531 is powered off, the first vertical moving device 452 lowers the absorbed flange to the corresponding station of the drilling and then the three-jaw positioning chuck 43 is fixed, the driving part 44 is driven to rotate, and then the driving device 46 is controlled to control the tap head 46 to tap the flange and tap the flange 46 to be machined. At the same time, the ram 4511 thus drives the slide 4512 in a reverse direction along the rail 4513, returning the first and second vertical movement devices 452, 457 to the previous station.
7.
