Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~3, in the utility model embodiment, a kind of automobile manufacture punching die with defencive function
Provision for disengagement, including die setting base 1 and punching die 2, the die setting base 1 are cylindrical body, and center is provided with mold peace
Hole 11 is filled, mould installion hole 11 is provided with the second material-dropping hole 12 in center below, and one week centered on second material-dropping hole 12
Threaded hole 13 and four bearing mounting grooves 14 there are four uniformly distributed, the bearing mounting groove 14 are spacedly distributed with threaded hole 13, institute
The bearing mounting groove 14 stated is provided with the thrust bearing 9 of clearance fit, and 14 depth specific thrust bearing of bearing mounting groove, 9 height is big
1mm is equipped with the punching die 2 of transition fit in the mould installion hole 11, and 2 center of punching die is provided with through-hole 5,
Through-hole 5 includes the upper through-hole 51 of upper section and the first material-dropping hole 52 of lower section, through-hole 51 on 52 aperture ratio of the first material-dropping hole
The big 5mm in aperture, 12 the first material-dropping hole of aperture ratio of the second material-dropping hole, the 52 big 5mm in aperture, to facilitate in punch process smoothly
Blanking, there are four mounting hole 4 and four removal holes 3 by 5 surrounding Zhou Junbu of through-hole, and 4 position of mounting hole is located at threaded hole 13
Surface, the second step hole 41 of mounting hole 4 including upper end and the tapped through hole 42 of lower end, the tapped through hole 42 and spiral shell
Pit 13 is provided with identical internal screw thread, and the removal hole 3 is located at the surface of thrust bearing 9, and removal hole 3 includes first step
Hole 31 and disassembly threaded hole 32, the disassembly threaded hole 32 are provided with internal screw thread, and punching die 2 passes through fixed spiral shell after being installed in place
Bolt 8 is fixed on die setting base 1, and mould upper surface 21 is generally aligned in the same plane with mounting base upper surface 15, fixing bolt 8 and punching
The elastic washer 6 and flat shim 7 for preventing loosening are installed, 8 height of head of fixing bolt is than second step hole 41 between punch die 2
