Description

Technical Field

[0001] The utility model belongs to the technical field of punching dies, and particularly relates to a punching die for metal connecting sheets with a protection structure. Background Technique

[0002] A punching die is a special process equipment that processes materials (metals or non-metals) into parts (or semi-finished products) in cold punching processing, and is called a cold punching die (commonly known as a cold die). Punching is a pressure processing method that applies pressure to the material by using a die installed on a press at room temperature to cause separation or plastic deformation, so as to obtain the required parts.

[0003] However, during the downward punching process of the punching die, the metal connecting sheet may generate elastic sheets or debris. These elastic sheets may fly out under the action of the tool pressure and hit the body of the staff, resulting in scratches on the body or eyes of the staff. Therefore, it is necessary to consider a safety protection structure to ensure that the operator will not be injured during use. Summary of the Invention

By setting the protection mechanism 2, it effectively avoids the staff being scratched by shrapnel or debris, and the protective cover can prevent the staff from accidentally contacting dangerous parts, resulting in serious injuries. By setting the punching mechanism 4, a buffering force is applied to the downward pressure during the punching process by using the buffering springs 46, which reduces the wear of the cutting tool 43 caused by too fast downward speed or too high acting force to a certain extent, and the setting of the collecting box 49 facilitates the recycling of metal debris.

[0035] A specific application of this embodiment is as follows: By setting up the protection mechanism 2, the staff grabs the grip rod 27 and pulls down the protective cover 25. Since the end of the torsion spring 24 is fixed inside the protective cover 25, rotating the protective cover 25 makes the torsion spring 24 inside the support rod 22 in a tightened state. The protective cover 25 rotates around the support rod 22, and the stop block 23 is used to block the protective cover 25 and fix it to the support rod 22. When pulling down the protective cover 25, the staff presses the button 214 to drive the latch rod 211 to slide rightward in the first chute 29. The latch rod 211 drives the spring 210 to make the spring 210 in a compressed state. At this time, the two latch blocks 213 on the protective cover 25 are pushed into the first chute 29. Then, the force acting on the button 214 is released, allowing the spring 210 to rebound and push the latch rod 211 to slide leftward. The latch rod 211 drives the two card slots 212 on it to move, enabling the two latch blocks 213 to be caught in the two card slots 212, thus completing the fixation of the protective cover 25. When it is necessary to repair or adjust the equipment after the punching is completed, press the button 214. Similarly, the fixed protective cover 25 is released. Since the torsion spring 24 is in a tightened state when the protective cover 25 is pulled down, when the protective cover 25 is released, the torsion spring 24 exerts a force to drive the protective cover 25 to rotate upward, and the elastic force of the torsion spring supports the protective cover 25 to stop falling. The protective glass 26 facilitates the staff to observe the punching process. When the staff presses the button to fix the protective cover, the protective cover can block the flying shrapnel or debris that may be generated during punching, effectively preventing the shrapnel or debris from scratching the staff, and the protective cover can also prevent serious injuries caused by the staff accidentally touching dangerous parts.

[0036] By setting up the cleaning mechanism 3, the debris generated by the device when punching the metal connecting piece falls into the cleaning housing 34 from the debris ports on the punching base 44 and the receiving plate 28. The double-shaft motor 32 synchronously drives the first bevel gears 33 on both output ends to rotate. Since the first bevel gear 33 meshes with the second bevel gear 38, the two first bevel gears 33 drive the two second bevel gears 38 to rotate. The two second bevel gears 38 synchronously drive the two threaded rods 36 to rotate. Since the first slider 37 is threadedly connected to the threaded rod 36, the two threaded rods 36 rotate to drive the two first sliders 37 to slide in the second chute 35. A connecting block 39 is connected between the two first sliders 37. The two first sliders 37 drive the connecting block 39 and several brush bristles 310 on the connecting block 39 to slide in the cleaning housing 34. The brush bristles 310 slide to clean the debris inside the cleaning housing 34 and on the bottom surface of the receiving plate 28, and sweep the debris towards the inclined surface on the inner wall of the punching die housing 1. The discharge chute 31 is provided to fix the double-shaft motor 32 and slide the metal connecting piece to the next processing procedure. It realizes the cleaning of the debris cut by the punching by using the double-shaft motor 32 to drive the connecting block 39 to drive several brush bristles 310, effectively reducing the impact of the flying debris on the device, preventing the debris from floating and scattering into the staff's eyes or being inhaled into the body, which endangers the life and health of the staff, and further enhancing the safety protection effect.

[0037] By setting up the punching mechanism 4, the output end of the hydraulic cylinder 41 on the support column 21 pushes the pressing block 42 downward. The pressing block 42 slides along a plurality of sliding rods 45 and drives the cutting tool 43 to punch the metal sheet on the punching base 44. A corresponding punching die is provided on the bottom surface of the pressing block 42. The buffer springs 46 on the plurality of sliding rods 45 are in a compressed state during the downward pressing of the pressing block 42 to buffer the downward pressing of the pressing block 42. After the cutting tool 43 punches the finished product, the metal connecting piece of the finished product slides down from the discharge chute 31. Under the cleaning action of the cleaning mechanism 3, the debris is swept into the punching die housing 1 and slides into the collection box 49. The staff can hold the handle 410 and pull out the collection box 49 from the punching die housing 1, driving the second slider 48 to slide in the third chute 47, which facilitates the removal of the collected debris. It realizes applying a buffering force to the downward pressure during the punching process by using the buffer spring 46, and to a certain extent reduces the wear of the cutting tool 43 caused by too fast downward pressing speed or too high acting force. Moreover, the setting of the collection box 49 facilitates the recycling of metal debris.
