Improved, be provided with locating core in the described reducing groove, described locating core is along the axial setting of reducing groove.Further steel pipe is positioned effect.
Improved, described patrix is provided with the stair-stepping through hole II of accommodating locating core, described through hole II is connected with the reducing groove, the superposed aperture of described through hole II is greater than the aperture that is positioned at the bottom, the upper end of described patrix is connected to the lower end of cope match-plate pattern so that the upper end of locating core is against on the lower surface of cope match-plate pattern, and the lower end of described locating core exceeds the lower end of through hole II and stretches into the reducing groove.Removably connect between locating core and the patrix, locating core replaceable or also replaceable different length adapted to processing request when locating core damaged.
Improved, the axial line of described locating core overlaps with the axial line of reducing groove.Guarantee the reducing symmetry that steel pipe is processed to form.
Improved, described cope match-plate pattern is provided with the stair-stepping through hole I of accommodating die shank, and described through hole I is positioned at the aperture of bottom greater than superposed aperture, the upper end of described patrix be connected to cope match-plate pattern the lower end so that the lower end of die shank be against on the upper surface of patrix.Removably connect between die shank and the cope match-plate pattern, replaceable when die shank damages.
Beneficial effect:
After adopting technique scheme, this utility model steel pipe throat mould
1) comprises the lower die structure that the upper die structure that is detachably connected on the punch press and positioning steel tube are used, described upper die structure be located at the top of lower die structure and under the driving of punch press relatively lower die structure move up and down, upper die structure comprises patrix, the lower end of patrix is provided with the reducing groove, steel pipe is positioned on the lower die structure, and punch press drives upper die structure and moves down the upper end formation reducing that makes steel pipe;
2) upper end of lower die structure is provided with the position limiting structure of avoiding upper die structure excessively to move down, and the stroke of restriction upper die structure avoids steel pipe processing to scrap, and upper die structure, lower die structure are played certain protective action.
