when the metal plate stamping machine starts to work, the handle 28 is held by hand, the right end face of the rubber pad 19 is tightly attached to the left end face of the metal plate to be stamped, the starting button 27 is pressed, the starting button 27 moves leftwards under the thrust action of the finger against the thrust action of the starting spring 30 to touch the contact switch 31, the contact switch 31 controls the air pump 16 and the motor 66 to start, the air pump 16 operates to pump air in the vacuum cavity 18 out through the ventilation cavity 15, so that the pressure in the vacuum cavity 18 is reduced, the metal plate is fixed on the right end face of the rubber pad 19 under the pressure action, the motor 66 is started to drive the driving shaft 65 to rotate, the driving shaft 65 rotates to drive the movable intermediate shaft 69 to rotate through the third belt wheel 64, the movable conveying belt 63 and the fourth belt wheel 68, the movable intermediate shaft 69 rotates to drive the front reversing gear shaft 53 to rotate through the driving bevel gear 50 and, the rotation direction of the front reversing gear 52 is opposite to the rotation direction of the rear reversing gear 52, the rotation of the front reversing gear 52 drives the conversion intermediate shaft 58 to rotate through the conversion gear 57, the conversion intermediate shaft 58 drives the conversion sleeve 61 to rotate, the conversion sleeve 61 drives the drill bit seat 14 to move rightwards through the rack gear 60 and the rack 26, the stamping spring 87 firstly loosens and then stretches to start to accumulate force, the drill bit seat 14 moves rightwards, the unlocking slide block 32 loses the magnetic attraction force of the magnet 47 and moves backwards under the pulling force of the unlocking spring 35, the unlocking pull rope 34 loosens, the locking pin 43 loses the pulling force of the unlocking pull rope 34 and moves rightwards under the pushing force of the locking spring 36 to the trigger cavity 42, the fixed gear shaft 11 is driven to rotate through the first belt pulley 72, the rotating transmission belt 71 and the second belt pulley 76 while the driving shaft 65 rotates, the fixed gear shaft 11 rotates to drive the drill, the drill head seat 14 moves rightwards to drive the fixing block 25 and the drill 20 to move rightwards, the drill 20 rotates while moving rightwards, and the drill 20 moves rightwards to drill a hole in the metal plate.

When the drill bit seat 14 moves rightmost to the right end of the stroke, the starting button 27 is released, the air pump 16 and the motor 66 stop working, the fixed block 25 just moves to the right side of the metal plate through the hole drilled by the drill bit 20, at the moment, the magnet 47 moves rightmost to the front side of the trigger cavity 42, the trigger slider 41 moves forwards under the action of the magnetic attraction force of the magnet 47 and overcomes the pulling force of the trigger spring 39 and is locked by the locking pin 43, the trigger slider 41 moves forwards to pull the tensioning block pull rope 37 and the conversion pull rope 38, the tensioning block 70 moves leftwards under the action of the pulling force of the tensioning block pull rope 37 and overcomes the pushing force of the tensioning block spring 75 to enable the rotating conveyor belt 71 to be loosened and incapable of normal operation, and the conversion gear 57 and the rear reversing gear 52 move backwards under the.

The fixed cylinder 82 is pushed to move leftwards, the fixed pin 85 enters the fixed pin groove 24, the fixed cylinder 82 is fixed on the drill bit shaft 46, the starting button 27 is pressed down again after the fixed cylinder 82 is fixed, the motor 66 is started to drive the drill bit seat 14 to move leftwards, so that the fixed cylinder 82 is driven to move leftwards, meanwhile, the speed of the left movement of the fixed cylinder 82 under the action of the pulling force of the stamping spring 87 is increased, the stamping block 77 stamps a metal plate in the left high-speed movement process of the fixed cylinder 82, the stamping spring 87 is in a release state after stamping, the drill bit seat 14 moves leftwards and resets, the stamping spring 87 restores to an initial state, the stamped metal block enters the stamping cavity 86, the stamping block 77 moves leftwards to touch the force storage plate 22, the force storage plate 22 overcomes the pushing force action of the force storage spring 17 to move leftwards under the pushing force of the stamping block 77, so that the metal plate is stamped, the drill bit seat 14, meanwhile, the unlocking slide block 32 moves forwards to reset under the action of the magnetic attraction of the magnet 47 and against the pulling force of the unlocking spring 35, the unlocking pull rope 34 is pulled, the locking pin 43 moves leftwards to reset under the action of the pulling force of the unlocking pull rope 34 and against the pushing force of the locking spring 36, the triggering slide block 41 is unlocked and moves backwards under the action of the pulling force of the triggering spring 39 to loosen the tensioning block pull rope 37 and the conversion pull rope 38, the tensioning block 70 moves rightwards to reset under the action of the pulling force of the tensioning block spring 75 and to re-tension the rotating transmission belt 71, the conversion disc 55 moves forwards to reset under the action of the pulling force of the conversion pull rope 38 and to re-engage the conversion gear 57 and the front reversing gear 52, the starting button 27 is released after the punching is finished, the motor 66 stops working, and when the punched metal block and the fixed cylinder 82 need to be taken out, the rotating knob, the fixing pin 85 moves outwards under the action of the pulling force of the fixing pull rope 81 and overcomes the pushing force of the fixing spring 84 to unlock the fixing cylinder 82 and the fixing block 25, the force storage plate 22 moves rightwards under the action of the pushing force of the force storage spring 17 to push the fixing cylinder 82 and the metal block to move rightwards, and the metal block is separated from the fixing cylinder 82.

The invention has the beneficial effects that: through at first fixing the punching press piece on the drill bit axle that passes the hole again to panel drilling, the punching press that removes the punching press piece at last and accomplish panel obtains required hole, this kind of punching press mode is applicable to under the different state of placing with the panel punching press of different materials, has increased the flexibility of punching press, the design of hand-held type can satisfy multiple construction environment simultaneously, it is more convenient to make the panel punching press, in addition, can obtain the punching press hole of different shapes through the punching press piece of changing different shapes.
