Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As Figure 1-Figure 4, a kind of short tube for air-conditioning duct processes lower die, including clamping shell 1 and moving gripper die 2,
Described 1 one end of clamping shell is equipped with the clamping cavity for installing the moving gripper die 2, and the moving gripper die 2 can be in the clamping cavity
Interior axial movement；
Middle part on the moving gripper die 2 is equipped with centre bore 2-2, and the both ends of the centre bore 2-2 are respectively equipped with the first ring
Connected in star 2-21 and second annular groove 2-22, the first annular groove 2-21 and second annular groove 2-22 respectively with it is described
