As shown in fig. 1-5, the utility model provides a punching mechanism, which comprises a clamping die 1, a core bar 2 movably arranged at one side of the clamping die 1, a first hole site 3 arranged at the upper side of the core bar 2, and a second hole site 4 arranged on the clamping die 1 and corresponding to the first hole site 3, wherein a punching die 5 capable of radially moving along the core bar 2 is arranged in the first hole site 3, so that when the clamping die 1 clamps a pipe fitting, the core bar 2 penetrates through the pipe fitting, and the pipe fitting is punched through the punching die 5.

When the pipe fitting is required to be punched, the pipe fitting is clamped at the clamping die, the second hole position corresponds to the punching position of the pipe fitting, then the core rod is penetrated inwards from one end of the pipe fitting to enter the position to be processed of the pipe fitting, the first hole position corresponds to the second hole position, the pipe fitting is punched from inside to outside through the punching die, and the core rod and the clamping die are avoided when the punching die punches a hole due to the fact that the first hole position and the second hole position correspond to the position of the punching processing, and the punching processing is completed on the pipe fitting.

The clamping die comprises two clamping blocks which are oppositely arranged, and the clamping blocks are controlled to clamp or loosen through an air cylinder.

Preferably, the side of the clamping die 1, which is positioned at the second hole site 4, is provided with an avoidance hole site 6.

Specifically, when the pipe fitting needs to be continuously punched, in order to avoid interference between the punched position and the clamping die, the avoidance hole site is arranged, so that when the pipe fitting is subjected to subsequent punching, the punched position is moved to the avoidance hole site, and meanwhile, the position to be processed is moved to the second hole site, so that the clamping die can still clamp and fix the pipe fitting.
