The lower die is fixed at the bottom of the press machine die through a lower die fixing seat, the upper die is fixed at the top of the press machine die through an upper die fixing seat, the forming oil cylinder is fixedly connected with the lower die through an oil cylinder fixing seat, the lower die closing correcting seat is positioned in the lower die and matched with an upper die closing correcting seat positioned in the upper die, and when die closing is carried out, the lower die closing correcting seat is buckled with the upper die closing correcting seat; the punching die comprises a punching oil cylinder, a punching fixing seat and a punching punch, the punching die is arranged in an upper die and a lower die, one end of the punching fixing seat is connected with the punching oil cylinder, the other end of the punching fixing seat is connected with the punching punch, the punching punch keeps consistent with the punching position of the tubular part to be punched, and after the tubular part is formed, the punching oil cylinder drives the punching punch through the punching fixing seat to punch the tubular part.
And the punching oil cylinder moves along the sliding rail when moving.
Furthermore, the number of the upper die clamping correction seat and the lower die clamping correction seat is at least 2.
Further, the number of the punching dies is 2-8.
The utility model discloses the beneficial effect who brings as follows:
firstly, the shaping of pipe and punching a hole are accomplished in same process, have reduced solitary punching a hole process, have saved time and equipment cost.
And secondly, the punching operation is immediately carried out after the tube blank is formed, the production efficiency is high, and the requirement of batch production is met.
Thirdly, the punching die can be arranged in any die and matched with the tube blank to complete punching operation, and the universality is strong.
