Background
The punching operation is to punch a hole in a pipe, a plate, or the like, and generally, the punching operation is performed by a punching die. In the punching operation of the pipe, the pipe is generally fixed on a punching die through a fixing clamp, and then the punching operation is carried out manually or automatically; because the material variety that tubular product used is more, consequently to the less tubular product of material hardness, the phenomenon that tubular product warp can appear when punching a hole again, and does not have the equipment that can solve this type of problem among the current tubular product structure of punching a hole, consequently can appear a large amount of newspaper pieces in the operation of punching a hole, is unfavorable for saving the cost that tubular product punched a hole. In addition, in the existing pipe punching processing, only one hole can be processed by one-time punching operation, so that the phenomenon that the pipe deforms due to overlarge overall stress during punching can be greatly avoided, but the processing efficiency is low, and the time for punching processing is not saved. In addition, in the pipe punching process, for the punching process with smaller hole pitch, the interval between holes is smaller, so that the supporting force of the pipe to the punching position is also smaller in the punching process, and the pipe is more likely to deform and bend during the processing, thereby influencing the processing quality. In the punching process, the operation mode of punching is usually to punch from outside to inside, so after punching, burrs can appear in the interior of the pipe, and the pipe is difficult to clean and process, so the quality of the pipe processing can be influenced. In summary, there are drawbacks.
