Generally, the metal plate is placed between the punching head and the die for extrusion, so that the metal plate is deformed. However, sometimes a metal plate may need multiple holes of different aperture sizes. In the prior art, multiple holes of different aperture sizes are punched out by replacing the stamping die and disassembling and repositioning the metal plate, but frequent disassembly will lead to low work efficiency.

[0006] The collector includes a plug rod, which is respectively sleeved on both sides of the main frame, and a central bin is sleeved on the outer side of the plug rod, and the central bin is fixedly installed inside the main frame. A pressure block is fixedly connected to one end of the plug rod inside the central bin, and an oblique slot hole is opened on the top side of the plug rod, and a triangular block is slidably installed inside the oblique slot hole. When the plug rod is pushed inward, the pressure block fixed on the inner end of the plug rod will squeeze the placement frame to play a role in squeezing and stabilizing it.

[0017] The present invention provides a punching device for electronic device boards. It has the following beneficial effects:

[0018] 1. The punching equipment for the electronic device board has a card block that is stuck at the bottom of the lower support plate, and the bottom of the card block is connected to the puncher, so the card block and the puncher will deflect accordingly to increase the reserved space, making it easier for the card block to be removed for replacement or repair.

[0020] 3. The punching equipment for electronic device boards plays a buffering role through the spring fixed at the top center of the punching ladder head. In addition, the number of punching components is five, and the punches at the bottom are of different shapes, so as to facilitate the replacement of the punches and punch out different hole types.

[0021] 4. The punching equipment for electronic device boards always maintains a slightly upward tilt through the abutment plate. Therefore, when the punch and the punched board squeeze it, it will deflect to the upper left, and then the bent rod moving downward will eventually hit the bottom sac. Because the bottom sac is filled with non-Newtonian fluid, the bottom sac will harden after the impact to limit the bent rod and the notched disk.

[0022] 5. The punching equipment for electronic device boards will form a torque through the surfaces of the resist plate and the notch disk that are in contact with the punched-down boards, so that the punched-down boards are subjected to a torsional force that causes them to flip to the left. With the downward squeezing of the resist plate and the upward movement of the notch disk, the punched-down boards will eventually flip to the left and fly up, and then be pulled by the upper traction plate and the lower traction plate respectively, and fall into the interior of the central warehouse for collection.

By rotating the support 23 to the left or right, wherein the support 23 is rotated by the rotating shaft 22, and the bottom of the support 23 is fixedly connected to the lower support plate 24, the lower support plate 24 will deflect to the left or right, and the clamping block 25 is clamped at the bottom of the lower support plate 24, and the bottom of the clamping block 25 is connected to the puncher 3, so the clamping block 25 and the puncher 3 will deflect accordingly, so as to increase the reserved space and facilitate the removal of the clamping block 25 for replacement or maintenance. Before this, the threaded rod 26 is not threadedly installed on the lower support plate 24.

[0035] The puncher 3 includes a slotted shell 31, the top of the slotted shell 31 is fixedly connected to the block 25, the inside of the slotted shell 31 is fixedly connected to a driver 38, the output end of the driver 38 is connected to a telescopic rod 39 through a coupling, a clamping strip 30 is arranged below the telescopic rod 39, the outer side of the clamping strip 30 is fixedly connected to the inner wall of the slotted shell 31, a punching assembly 32 is slidably installed inside the slotted shell 31, the number of the punching assemblies 32 is five and they are arranged in the form of a circular array inside the slotted shell 31, and the bottom of the punching assembly 32 is respectively fixedly connected with a punching fine head 33, a punching cone head 34, a punching ladder head 35, a punching column head 36 and a punching round head 37.

[0036] The punching assembly 32 includes a fixed sleeve 323, which is slidably installed inside the slotted shell 31. The top of the fixed sleeve 323 is fixedly connected to a limiting ring 322, and the bottom of the limiting ring 322 is fixedly connected to a pressure rod 321. The pressure rod 321 is slidably installed inside the fixed sleeve 323. The outer side of the pressure rod 321 is fixedly connected to an insert ring 324. The surface of the insert ring 324 is sleeved with an insert plate 325. The bottom of the insert plate 325 is fixedly connected to the punching ladder head 35. The center position of the top of the punching ladder head 35 is fixedly connected to a spring 326, and the end of the spring 326 away from the punching ladder head 35 is fixedly connected to the pressure rod 321. After the above-mentioned disassembly, repair or replacement, the threaded rod 26 is threadedly installed on the lower support plate 24 to fix it, and then one of the five punching assemblies 32 is moved inward along the inner side of the slotted shell 31. At this time, the limiting ring 322 fixed on the top of the fixing sleeve 323 will enter the center position inside the slotted shell 31. At this time, the top of the clamping strip 30 fixed at the center position inside the slotted shell 31 will limit the downward movement of the limiting ring 322. At the same time, the end of the clamping strip 30 close to the center of the slotted shell 31 will squeeze the fixing sleeve 323, wherein the fixing sleeve 323 has a certain toughness, and the cross-sectional area of ​​the fixing sleeve 323 is slightly larger than the area surrounded by the inner ends of several clamping strips 30. Therefore, the clamping strip 30 will squeeze and fix the fixing sleeve 323 to fix the fixing sleeve 323.

[0037] Then, the driver 38 is started, so that the telescopic rod 39 connected to it through the coupling will move downward, and the telescopic rod 39 will squeeze the pressure rod 321 slidably installed inside the fixed sleeve 323, so that the pressure rod 321 moves downward, wherein the outer side of the pressure rod 321 is fixedly connected with an insert ring 324, and the surface of the insert ring 324 is sleeved with an insert plate 325, and the bottom of the insert plate 325 is fixedly connected with a punching ladder head 35, so that the punching ladder head 35 will eventually move downward and punch the device plate 40 to achieve a punching effect.

[0038] The spring 326 fixed at the top center of the punching ladder head 35 plays a buffering role. In addition, the number of punching assemblies 32 is five, and the punches at the bottom are of different shapes to facilitate the replacement of the punches and the punching of different hole types.

[0039] The second embodiment, as Figure 5-Figure 8As shown, the collector 4 includes an insertion rod 41, and the insertion rod 41 is respectively sleeved on both sides of the main frame 1. The outer side of the insertion rod 41 is sleeved with a central bin 46, and the central bin 46 is fixedly installed inside the main frame 1. One end of the insertion rod 41 inside the central bin 46 is fixedly connected to a pressure block 42, and an oblique slot hole 401 is opened on the top side of the insertion rod 41. A triangular block 43 is slidably installed inside the oblique slot hole 401. A limit strip 44 is arranged above the triangular block 43, and slide grooves 45 are slidably installed at both ends of the limit strip 44. The slide grooves 45 are opened in the central bin 46. The top of the central bin 46 is threadedly connected to the threaded rod 26, and a placement frame 47 is fixedly connected to the center position of the central bin 46. Through holes 48 are provided on both sides of the placement frame 47. A device plate 40 is slidably installed inside the through holes 48. A collection component 49 is provided below the device plate 40. The collection component 49 is fixedly installed inside the placement frame 47. A bottom capsule 402 is provided below the collection component 49. Both ends of the bottom capsule 402 are fixedly connected to external rods 403, and the external rods 403 are sleeved on the outside of the central bin 46. Pushing the insertion rod 41 inwards causes the pressing block 42 fixed on the inner end of the insertion rod 41 to squeeze the placement frame 47 to play a role in squeezing and stabilizing it. Then, the triangular block 43 is squeezed downward, so that the triangular block 43 moves downward along the inclined slot hole 401. At this time, the inclined side of the triangular block 43 will squeeze the top of the pressing block 42, and then the limiting strip 44 is slid along the inside of the slide slot 45 to the top of the triangular block 43, and then the limiting strip 44 is squeezed downward, wherein the limiting strip 44 has the ability to stretch up and down to fix the triangular block 43.

[0040] The collecting assembly 49 includes a fixing rod 491, both ends of which are fixedly connected to the inner side of the placing frame 47, a sleeve 492 is fixedly connected to the outer side of the fixing rod 491, a clamping frame 493 is fixedly connected to the top of the sleeve 492, a deformation ring 4903 is fixedly connected to the inner sides of the clamping frame 493 and the sleeve 492, an elastic bar 494 is fixedly connected to the bottom of the sleeve 492, a bent rod 495 is fixedly connected to the end of the elastic bar 494 away from the sleeve 492, and a notched disk 496 is fixedly connected to the end of the bent rod 495 away from the elastic bar 494. A butt plate 499 is provided on the side of the notch disk 496, and the outer side of the butt plate 499 is rotatably connected to a hinge seat 4901, and the top of the hinge seat 4901 is fixedly connected to a vertical plate 498, and the bottom of the vertical plate 498 is fixedly connected to a hole plate 497, and the outer side of the hole plate 497 is fixedly connected to the placement frame 47, and an upper traction plate 4902 is provided above the vertical plate 498, and the top of the upper traction plate 4902 is fixedly connected to the sleeve 492, and the outer side of the sleeve 492 is provided with a lower traction plate 490, and the lower traction plate 490 is fixedly connected to the inner wall of the placement frame 47. Then, the device plate 40 is inserted from the through hole 48 and placed on the clamping frame 493, and then the device plate 40 is punched, wherein the deformation ring 4903 respectively fixed on the inner wall of the clamping frame 493 and the sleeve 492 can be contracted or expanded to play a role in limiting the punch.

[0041] When the device plate 40 is punched, the punching assembly 32 and the punch will continue to move downward due to inertia, and the punch will move the punched plate downward together and squeeze it on the notched disk 496, wherein the cross-sectional area of ​​the punched plate is slightly larger than the size of the punch, because the bottom of the notched disk 496 is fixedly connected with a bent rod 495, and the top of the bent rod 495 is connected to the spring bar 494, so the notched disk 496 will stretch the spring bar 494 to continue to move downward, so the punched plate, the punch and the punching assembly 32 will continue to move downward. When the punch and the plate rushing down, the plate 499 will be squeezed, wherein the plate 499 is deflected by the hinge seat 4901, and the plate 499 is always kept in a slightly tilted upward state, so when the punch and the plate rushing down squeeze it, it will be deflected to the upper left, and then the bent rod 495 moving downward will eventually hit the bottom bag 402. Because the bottom bag 402 is filled with non-Newtonian fluid, the bottom bag 402 will harden after the impact to limit the bent rod 495 and the notched disk 496. When the punching is completed, the punch assembly 32 and the punch head will return to their original positions, and the notched disk 496 and the punched-down plate will also move upward through the spring bar 494. Because the speed at which the punch assembly 32 returns to its original position is much greater than the speed at which the spring bar 494 recovers, the resisting plate 499 that has deflected to the upper left will return to its original state so that its bottom will contact part of the surface of the top of the punched-down plate. However, the punched-down plate will continue to move upward, and most of the bottom surface of the punched-down plate will contact the notched disk 496. Therefore, the surfaces of the resisting plate 499 and the notched disk 496 that are in contact with the punched-down plate will form a torque, thereby causing the punched-down plate to be subjected to a torsional force that flips to the left. With the downward squeezing of the resisting plate 499 and the upward movement of the notched disk 496, the punched-down plate will eventually flip to the left and fly up, and then be pulled by the upper traction plate 4902 and the lower traction plate 490 respectively, and fall into the interior of the central bin 46 for collection.

[0042] The upward deflection angle of the support plate 499 is limited because it is blocked by the hinge seat 4901.

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
