Abstract
The utility model provides a hole extruding and hole flanging die of a numerical control turret punch press. The hole extruding and hole flanging die is large in processed flanging height and suitable for subsequent processing on a flanging under the condition of a small punching diameter. An upper die core is provided with a first upper die core section, a second upper die core section and a third upper die core section, diameters of the first upper die core section, the second upper die core section and the third upper die core section are sequentially reduced, the upper portion of the third upper die core section is cylindrical while the lower portion of the third upper die core section is conical, and a gap between the largest-diameter portion of the third upper die core section and core hole of a lower die return core is smaller than the thickness of a plate. The hole extruding and hole flanging die breaks a natural mode of traditional hole flanging of punched holes, a special conical upper die core is adopted, and the gap between the upper die core and the lower die return core is designed according to the plate thickness, and during punching, the upper die core drives the plate to extrude into the lower die return core to enable the flanging to be thinned and heightened, and consequently the high flanging can be obtained under the condition of the small punching diameter.
Description
Technical field
The utility model relates to numerical control mould, relates in particular to a kind of crowded hole hole flanging mold that is suitable for NC turret punch machine.
Background technology
At present, along with parts suitability for industrialized production, the requirement of counter-punching die tool also progressively improves, and aspect numerical control turret punching, adopts punching hole composite die more, i.e. subpunch pre-punched hole, then on the basis of pre-punched hole, carry out flange.But use the formed in mould flange height of this class often not high, make the following process (for example machining screw on flange) to piercing and flanging bring great difficulty.
Utility model content
The utility model, for above problem, provides a kind of in the situation that punching hole diameter is less, makes flange height relatively high, and is adapted at carrying out on flange the crowded hole hole flanging mold of following process.
The technical solution of the utility model is: comprise upper die component and lower membrane module, described upper die component comprises attacking head, cylindrical spring, guide pin bushing and upper mold core, and described guide pin bushing lower end is provided with pilot hole; Described lower membrane module comprises counterdie, counterdie material returned core, dish spring and counterdie fixed head, described upper mold core is coaxial with described counterdie material returned core, described counterdie material returned core has counterdie material returned core core hole, described upper mold core is provided with upper mold core section one, upper mold core section two and upper mold core section three, and the diameter of described upper mold core section one, upper mold core Duan Erzhi upper mold core section three reduces successively;
Described upper mold core section three tops are that cylindric, bottom is coniform;
It is thick that gap between the maximum gauge position of described upper mold core section three and described counterdie material returned core core hole is less than plate material.
Described in described upper mold core Duan Sanyu, pilot hole is matched in clearance.
The cone point of described upper mold core section three top in described guide pin bushing lower surface under off working state.
The break traditions natural mode of punching hole flanging of the utility model, adopt special circular cone upper mold core, simultaneously according to the gap of sheet thickness design upper mold core and counterdie material returned core, realize in the time of punching, drive plate to push in counterdie material returned core by upper mold core, make the thick attenuate of flange material, flange height increases, finally realize in the situation that punching hole diameter is less, obtain relatively high flange.

Detailed description of the invention
The utility model as shown in Figure 1, comprise upper die component and lower membrane module, described upper die component comprises attacking head 1, cylindrical spring 2, guide pin bushing 5 and upper mold core 7, described guide pin bushing 5 is cylindric, lower end is provided with pilot hole 51, at described guide pin bushing, 5 upper port places are provided with spring base 3, described cylindrical spring 2 is set on die shank 6, be provided with polyurethane chain shot 4 in described spring base 3 lower ends and described die shank 6 cooperation places, described die shank 6 upper ends are threaded connection on described attacking head 1, lower end is connected to described upper mold core 7, described upper mold core 7 is provided with columned upper mold core section 1, upper mold core section 2 72 and upper mold core section 3 73, described upper mold core section 1, upper mold core section 2 72 to the diameter of upper mold core section 3 73 reduces successively, described upper mold core section 3 73 tops are cylindric, it is coniform that bottom is, be matched in clearance with described pilot hole 51, the cone point of described upper mold core section 3 73 is the top in described guide pin bushing 5 lower surfaces under off working state, guarantee in the course of work, first push down plate by described guide pin bushing 5 lower surfaces, and then break plate by the cone spine of described upper mold core section 3 73, thereby ensure service life and the stamping-out quality of described upper mold core section 3 73.
Described lower membrane module comprises counterdie 8, counterdie material returned core 9, dish spring 10, counterdie fixed head 11 and cross recess countersunk head screw 12, described upper mold core 7 is coaxial with described counterdie material returned core 9, described counterdie material returned core 9 has counterdie material returned core core hole 91, and it is thick that the gap between the maximum gauge position of described upper mold core section 3 73 and described counterdie material returned core core hole 91 is less than plate material; Described counterdie 8 is fixing by described cross recess countersunk head screw 12 with described counterdie fixed head 11, makes to form a die cavity in the middle of described counterdie 8 and described counterdie fixed head 11; In described die cavity, by consistent described dish spring 10 being connected in described counterdie 89 activities of described counterdie material returned core of some specifications.
Operation principle of the present utility model is different from general piercing and flanging compound die, its operation principle is (as shown in the design sketch of Fig. 2-4): a complete sheet material is placed in to mould below, start punch press, because upper mold core section three bottoms are coniform, first with cone point, sheet material is pierced through, along with moving down of patrix stroke, upper mold core section three conus portion bands are lived sheet material and are moved downward, and clamp-on in counterdie material returned core; Because upper mold core Duan Sanyu counterdie material returned core fit clearance is less than sheet metal thickness, so the plate of sheet material flange is had to squeezing action, make sheet thickness attenuation, flange height processing, even the punching that aperture is less, also can by squeezing hole, to realize aperture little, the object that flange is high.
