The invention provides a method for using a punching device for a bending section based on a movable ledge upper edge structure, which comprises the following steps,
The first step: all electric equipment is connected with the lead and electrified, and then the bending section of the movable ledge is placed between the pushing block 7 and the two baffles. Then, the transverse sliding motor 14 is started, the transverse sliding motor 14 drives the bidirectional screw rod 9 to rotate through the worm wheel 11 and the worm 12 which are meshed with each other, and as the two baffles are respectively screwed on two sections of external threads with opposite rotation directions of the bidirectional screw rod 9, the two baffles are driven to be close to each other or far away from each other when the bidirectional screw rod 9 rotates, so that the interval between one ends of baffle bodies 17 of the two baffles, on which the connecting rods 16 are arranged, corresponds to the movable ledge, and the transverse sliding motor 14 is stopped.
And a second step of: the longitudinal sliding motor 5 is started, the first screw 4 is driven to rotate through the longitudinal sliding motor 5, the first moving seat 6 is in threaded connection with the first screw 4, the first moving seat 6 is driven to slide forwards in the longitudinal sliding groove by the rotating first screw 4, the two ends of the first spring 8 are respectively connected with the first moving seat 6 and the push block 7, the first moving seat 6 drives the push block 7 to slide forwards in the longitudinal sliding groove through the first spring 8, the push block 7 pushes the movable ledge forwards, the first spring 8 is in a compressed state, and rigid collision of the push block 7 when pushing the movable ledge is avoided through the first spring 8. When the push block 7 pushes the movable ledge to move to contact with one end of the baffle bodies 17 of the two baffles, which are provided with the connecting rods 16, the longitudinal sliding motor 5 is stopped.
And a third step of: the electric push rods 18 on the two sides are started, the piston rods of the electric push rods 18 extend out, one ends, which are not provided with connecting rods 16, of the baffle bodies 17 of the two baffles rotate backwards around the connecting rods 16 until one ends, which are not provided with the connecting rods 16, of the baffle bodies 17 of the two baffles are contacted with the movable ledge, the bending degree of the baffle bodies 17 and the movable ledge is adapted, and then the electric push rods 18 are stopped. At this time, the movable ledge is stably clamped by the two baffles and the pushing block 7, so that the movable ledge is positioned.
Fourth step: after the living ledge is clamped and secured, the angle of the support tube 26 is adjusted according to the desired location of the opening. The positioning bolt is unscrewed first, the end part of the positioning bolt is separated from contact with the inner bottom surface of the arc-shaped positioning groove, so that the bearing tube 26 can rotate around the first connecting column 29, the positioning bolt slides in the arc-shaped positioning groove in the rotating process of the bearing tube 26, and the second connecting column 30 slides in the arc-shaped sliding groove. After the bearing tube 26 is rotated, the end part of the positioning bolt is tightly contacted with the inner bottom surface of the arc-shaped positioning groove by screwing the positioning bolt, so that the bearing tube 26 cannot rotate around the first connecting column 29, and the angle adjustment of the bearing tube 26 is finished; the support tube 26, when rotated, moves the drill bit 37 in an arc. After the angle adjustment of the supporting tube 26 is completed, the hand wheel 32 is rotated, the third screw 31 is driven to rotate inside the supporting tube 26 by the hand wheel 32, and the second moving seat 33 is screwed with the third screw 31, so that the second moving seat 33 is driven to slide inside the opening at the lower end of the supporting tube 26, and the drill bit 37 is driven to slide along a straight line until the drill bit 37 corresponds to the position on the movable ledge, which needs to be perforated.
Fifth step: the lifting motor 24 and the driving motor 35 are started, the second screw 21 is driven to rotate by the lifting motor 24, and as one end of the moving rod 23 is in threaded connection with the second screw 21, the other end of the moving rod 23 is sleeved on the outer side of the guide rod 22, so that the moving rod 23 slides along the vertical direction under the driving of the second screw 21, and the drill bit 37 is driven to descend. In the process of descending the drill bit 37, the driving motor 35 drives the spline cylinder 36 to rotate, the spline cylinder 36 drives the spline shaft 38 to rotate, and the spline shaft 38 drives the drill bit 37 to rotate. When the drill bit 37 contacts the living ledge, the second spring 39 is compressed so that the drill bit 37 begins to retract slightly, ensuring that the drill bit 37 does not come into direct rigid contact with the living ledge, thereby protecting the drill bit 37. While the drill bit 37 is lowered, it is simultaneously rotated to open holes in the curved section of the living ledge. When the hole is formed, the elevating motor 24 rotates reversely, so that the drill bit 37 starts to ascend, and is separated from the movable ledge.
Sixth step: when the curved section of the living ledge is to be polished, the arcuate push plate 40 is removed from the rear end opening of the mounting slot, with the sand roller 44 exposed. The sanding roller 44 is brought into contact with the movable ledge by starting the longitudinal sliding motor 5, and then the sanding motor 41 is started, and the sanding motor 41 drives the sanding roller 44 to rotate through the driving gear 42 and the driven gear 43 which are meshed, so that the curved section of the movable ledge is sanded. After finishing polishing, the longitudinal sliding motor 5 and the transverse sliding motor 14 are controlled to reversely rotate, so that the push block 7 and the baffle body 17 are separated from the movable ledge. And finally, powering off all the electric equipment and taking down the movable ledge.
