Working principle of the present invention:

The driving part 1 adopted in the present invention is a motor, and is externally connected to a power supply and a control switch when in use. Firstly, the metal plate 22 to be punched is put into the first limiting groove 23 in parallel through the second limiting groove 25 , and the metal plate 22 is supported by the first limiting groove 23 and the second limiting groove 25 . When the driving part 1 is not activated, the eccentric part 6 does not rotate, and the rotating part 12 does not rotate either. At this time, the gear teeth 13-1 of the half gear 13 mesh with the gear 14; when the driving part 1 is started, the driving part 1 drives the eccentric part 6 to rotate, the eccentric part 6 drives the rotating part 12 to rotate, and the rotation of the rotating part 12 drives the half gear 13 to rotate. Rotation, the rotation of the gear 14 drives the movement of the rack 15 meshed with the gear 14. Since the top of the rack 15 is fixedly connected with the laterally moving plate 21, the laterally moving plate 21 and the rack 15 move synchronously. The lateral movement drives the lateral movement of the second fixed plate 11 connected to the lateral moving plate 21, and the lateral movement of the second fixed plate 11 causes the metal plate 22 in contact with the first limiting groove 23 to move laterally under the drive of friction, Thus, when the driving part 1 is activated and the rotation angle of the eccentric part 6 is 0-90°, the metal plate 22 moves, but at this time the contact point between the eccentric part 6 and the pulley 7-1 has not reached the lowest point, so this When the rotation of the eccentric part 6 did not make the punch 20 to punch the metal plate 22; A quarter, and when the eccentric member 6 rotates 90°, the half gear 13 rotates a quarter turn, so the gear teeth 13-1 of the half gear 13 are no longer meshed with the gear 14, so at this time, the lateral movement plate 21 When the lateral movement is stopped, the metal plate 22 also stops lateral movement. Since the eccentric member 6 rotates by 90°, the end with a larger arc of the eccentric member 6 will squeeze the limiting plate 8 on one side, causing the limiting plate 8 to move longitudinally. , when the limit plate 8 moves longitudinally, the second spring 2-2-1 will be squeezed by the second slider 8-1, and the longitudinal movement of the limit plate 8 drives the longitudinal movement plate 9 to move longitudinally. The longitudinally moving plate 9 is movably connected to the first support plate 3, so the longitudinally moving plate 9 can move longitudinally on the upper surface of the first support plate 3, and the longitudinal movement of the longitudinally moving plate 9 drives the movement in the first limiting groove 23. The metal plate 22 moves longitudinally, and the pulley 7-1 slides to the lowest point of the eccentric member 6 while the eccentric member 6 rotates, and when the eccentric member 6 rotates 90°, the contact point between the pulley 7-1 and the eccentric member 6 is the lowest point, so the rotation of the eccentric member 6 at this time makes the punch 20 punch the metal plate 22, and because the first spring 24 limits the lateral movement plate 21, the transverse movement plate 21 does not move longitudinally. Therefore, the collision of the rack 15 to the gear 14 can be avoided, so when the eccentric member 6 rotates 90°, the metal plate 22 moves longitudinally, and the punch 20 punches the metal plate 22; when the eccentric member 6 rotates 180° At this time, the gear teeth 13-1 of the half gear 13 do not mesh with the gear 14, so the metal plate 22 does not move laterally, and the connecting rod 17 is driven by the rotation of the eccentric member 6 to drive the T-shaped slider 18 on the T-shaped slider. Slot 2-1 It moves upwards, thereby driving the punching arm 19 to move upwards. At this time, no punching occurs. At the same time, because the eccentric member 6 rotates 90°, the second slider 8-1 squeezes the second spring 2-2-1. When the eccentric member 6 rotates 180°, the eccentric member 6 has no pressing force on the limit plate 8, so that the second spring 2-2-1 generates a reset force on the second slider 8-1, so that the second slider Block 8-1 drives the limiting plate 8 and the longitudinal moving plate 9 to reset; when the eccentric member 6 rotates 270°, at this time, the gear teeth 13-1 of the half gear 13 are not meshed with the gear 14, and the eccentric member 6 is on the limit. The position plate 8 is extruded, and the movement track of the limit plate 8 is opposite to the direction when the eccentric member 6 rotates 90°. Similarly, the longitudinal moving plate 9 also moves in the opposite direction, which drives the metal plate 22 to move in the opposite direction. And now the contact point between the pulley 7-1 and the eccentric part 6 is the lowest point, so the rotation of the eccentric part 6 makes the punch 20 punch the metal plate 22, so when the eccentric part 6 rotates 270 °, the metal plate 22 moves longitudinally in the opposite direction when the eccentric part 6 rotates 90°, and the punch 20 punches the metal plate 22; when the eccentric part 6 rotates 270°~360°, the gear teeth 13 of the half gear 13 -1 starts to mesh with the gear 14, and the driving gear 14 rotates, thereby driving the lateral movement of the rack 15, and then causing the metal plate 22 to move laterally. , will cause the first spring 24 to gradually increase the reset force of the limiting plate 8, thereby driving the metal plate 22 to gradually reset to the initial position; The gear teeth 13-1 are meshed with the gear 14. With the rotation of the eccentric member 6, the rotating member 12 drives the half gear 13 to rotate synchronously, realizing the lateral movement of the metal plate 22, and intermittently squeezing the limit plate 8, thereby realizing the above-mentioned alignment of the metal plate 22. When punching, it can not only punch holes in the longitudinal direction, but also punch holes in the transverse direction. When the number of punched holes reaches the preset number, the driving part 1 can be closed, and the metal plate 22 can be removed, thereby satisfying the The needs of producers have improved production efficiency and market competitiveness.

To sum up, the present invention provides an automatic punching device for metal plates, which controls the rotation of the eccentric part through the driving part, so that the eccentric part squeezes the limit plate, thereby driving the movement of the longitudinally moving plate, and then making the metal It can move longitudinally, and can punch holes after the longitudinal movement, which meets the needs of producers for longitudinal movement and punching of metal plates; through the rotation of the eccentric, it drives the rotation of the half gear, and the teeth of the half gear rotate When it is in the state of meshing with the gear, it will drive the gear to rotate, thereby driving the rack meshed with the gear to move, and the movement of the rack drives the lateral movement of the plate and the metal plate, thus satisfying the requirements of the producer for the metal plate. The need for lateral movement; the movement trajectory of the metal plate when it starts to move from a static state is: lateral movement-vertical movement-reset-longitudinal movement-lateral movement-reset, through multiple cycles of the above movement trajectory, the punching position can be avoided Repeatedly, it can realize the horizontal and vertical punching of the metal plate separately, which improves the production efficiency and market competitiveness; the change of the entire moving track is completed through the control of one driving part, and the control of multiple driving parts is avoided. increase in cost.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should all belong to the protection scope of the appended claims of the present invention.
