The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
As shown in Figure 1, the utility model comprises patrix 1, and patrix 1 comprises upper bolster 11 and the die plate insert 12 that is fixed on upper bolster 11 lower surfaces; The below of patrix 1 be provided with one be used to place pending plate 6 blank holder 2, the upper surface of blank holder 2 is corresponding with the horizontal component of the lower surface of die plate insert 12; The lower surface of blank holder 2 is provided with a plurality of vertical push rods 4, and the other end of push rod 4 is connected with the press hydraulic die cushion; Be fixed with a plurality of identical balance weights 5 around the die parting line of the upper surface of blank holder 2, the height of balance weight 5 is slightly larger than the thickness of plate 6; The below of blank holder 2 is provided with counterdie 3; Counterdie 3 comprises die shoe 31, and die shoe 31 comprises die shoe body 31a and along the upwardly extending die shoe flange of the edge-perpendicular 31b of die shoe body 31a; The upper surface vertical fixing of die shoe body 31a has a plurality of identical nitrogen springs 32; Be pressed with an installing plate 33 on the nitrogen spring 32, the edge of installing plate 33 cooperates with the internal surface gaps of die shoe flange 31b, is provided with guide plate 37 between the inner surface of the edge of installing plate 33 and die shoe flange 31b; The upper surface center fixation of installing plate 33 has punch insert 34, and the convex surface of punch insert 34 is corresponding with the concave surface of die plate insert 12, and the centre of blank holder 2 is provided with first through hole, and the maximum gauge of punch insert 34 is slightly less than the internal diameter of first through hole; The central vertical of die shoe body 31a upper surface is fixed with hole flanging drift 35; The peak of hole flanging drift 35 can be a little less than the upper surface of punch insert 34; Installing plate 33 and punch insert 34 are provided with second through hole corresponding to the position of hole flanging drift 35, and hole flanging drift 35 cooperates with second via clearance; The center of die plate insert 12 is provided with third through-hole, and third through-hole and hole flanging drift 35 are on same axis, and the radial distance of the outer diametric plane of the aperture surface of third through-hole and hole flanging drift 35 is slightly larger than the thickness of plate 6; The upper surface of die shoe body 31a is fixed with the dead piece 36 of a plurality of identical piers, and the dead piece 36 of pier is positioned at the below of installing plate 33; The position of said installing plate 33 and said die shoe 31 corresponding said push rods 4 is provided with fourth hole, push rod 4 and fourth hole matched in clearance.
As shown in Figure 2, because the hydraulic coupling of the push rod 4 of support blank holder 2 is less, patrix 1 is together descending with blank holder 2.Plate 6 successively contacts with die plate insert 12 with punch insert 34, the beginning drawing and forming.In this process; Because the support force of nitrogen spring 32 is greater than the plastic force of plate 6; Installing plate 33 basic maintenances are motionless, and hole flanging drift 35 is positioned at punch insert 34 inside fully, with on the plate 6 does not treat that the hole flanging zone comes in contact; Plate 6 correspondence positions can not cool off fast, still keep higher temperature and formability.When plate 6 contacted with die plate insert 12 with punch insert 34 fully, plate 6 basic shaping under punch insert 34, die plate insert 12 effects finished, and the heat forming technology of phase I is accomplished.
As shown in Figure 3, patrix 1 continues descending.The downforce of press slide is greater than the support force of nitrogen spring 32, and installing plate 33 is under guide plate 37 guide effects, and is together descending with punch insert 34, plate 6.Because hole flanging drift 34 is to be fixed on the die shoe 31; And produce relative motion upwards between the punch insert 34, contact and begin hole flanging, contact with the dead piece 36 of the pier on being fixed on die shoe 31 until installing plate 33 with the hole flanging zone of treating on the plate 6; Arrive lower dead center, hot flange hole technology finishes.
It is to be noted; The specification of nitrogen spring 32, quantity and arrangement form; Need to carry out designing and calculating according to punch insert 34 and installing plate 33 weight and plastic force size; The total support force that guarantees nitrogen spring 32 can be guaranteed after the hot forming operation is thoroughly accomplished, to carry out hot hole flanging again greater than punch insert 34 and installing plate 33 weight and plastic force sum like this.
After plate 6 hot formings and hot hole flanging finish,, generally can be coated on punch insert 34 and the hole flanging drift 35 because cooling is shunk.During discharging, up along with press slide and patrix 1, the plastic force of press slide is removed, and under the support force effect of nitrogen spring 32, punch insert 34 moves upward with installing plate 33 relative hole flanging drifts 35, makes the plate 6 and 35 disengagements of hole flanging drift that have been shaped.Then, under the effect of push rod 4, blank holder 2 relative punch inserts 34 move upward, and the plate 6 that has been shaped is thrown off with punch insert 34, and the discharging manipulator can be taken the plate that has been shaped 6 away.
The utility model can carry out conventional hot forming earlier in same operation, before the cooling of plate 6 corresponding positions, accomplish hot hole flanging then, realizes the manufacturing than complex parts.
More than a kind of hot-forming die that possesses shaping hole flanging complex function that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum; This description should not be construed as the restriction to the utility model, and all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
