Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1 and Fig. 2, a kind of shown anti-rebound sheet material flanging die, including upper bolster 1, die shoe 2, with
Lower molding glassware 6 that die holder 2 is slidably connected, upper bolster 1 is fixedly mounted on by trip bolt 14 and coordinated with lower molding glassware 6
Carry out the flange cutter block 3 of flange and be fixedly mounted on the upper molding glassware 7 of upper bolster 1, in addition to be fixedly mounted on die shoe 2
And the nitrogen spring 5 of the symmetrical distribution of lower molding glassware 6 is withstood, the upper end of nitrogen spring 5 is fixed with cushion block 11, it is to avoid
Lower molding glassware 6 is directly contacted with nitrogen spring 5.
The lower molding glassware 6 is slidably connected by being located at the guide plate 12 of lower molding glassware 6 side with die shoe 2.Lower mould
The edge of eccentric swage 6 is uniformly provided with multiple second balance weights 9, for transmitting the power that upper bolster 1 is moved downward, it is to avoid upper bolster 1 with
Lower molding glassware 6 is directly contacted.
The side of die shoe 2 is provided with side pin 13, the movement travel for limiting lower molding glassware 6.Four of die shoe 2
Angle is provided with the first balance weight 8, for bearing or balancing power when upper bolster 1 moves to minimum point, it is to avoid upper bolster 1 and lower mould
Seat 2 is directly contacted, because of the limitation in mould structure and space, and two the first balance weights 8 are set on each angle.Also set on die shoe 2
There are several the 3rd balance weights 10 coordinated with the lower downside of molding glassware 6, minimum point is moved to for balancing the lower flange of molding glassware 6
When power.
Be provided with upper bolster 1 and the contact site of die shoe 2 carried out when coordinating upper bolster 1 and die shoe 2 it is spacing spacing
Mechanism, the position-limit mechanism includes multiple front and rear conical limit blocks 4 for being symmetricly set on the upside of die shoe 2 and is located at upper bolster 1
The spacing hole that downside coordinates with the conical limit block 4.
During specific works, upper molding glassware 6 and flange cutter block 3 are moved downwardly together with upper bolster 1.When motion certain distance
Upper bolster 1 is spacing by corresponding spacing hole progress on conical balance block 4 and upper bolster 1 with die shoe 2 afterwards, then upper molding compound
Device 6 contacts with the type face of die shoe 3 and starts binder, while plate is contacted with flange cutter block 3, with the progress of motion, upper bolster 1
Local to be contacted with the second balance weight 9, the lower molding stress of glassware 6 is moved downward by guide plate 12, passes through the power transmission of cushion block 11 and then pressure
Contracting nitrogen spring 5, starts flange work.When upper bolster 1 moves to minimum point, lower molding glassware 6 connects with the 3rd balance weight 10
Touch, upper bolster 1 is contacted with the first balance weight 8, and flange terminates.Subsequent upper bolster 1 is moved upwards, upper molding glassware 7 and flange knife
Block 3 makees drawback movement upwards with upper bolster 1.Meanwhile, nitrogen spring 5 release pressure, lower molding glassware 6 by guide plate 12 to
Upper motion, until upper bolster 1 departs from the second balance weight 9, returns to initial position, that is, returns to peak, lower molding glassware 6 is in nitrogen
Vertically to the overall liftout backhaul of flange product to initial position in the presence of the release of the pressure of gas spring 5, one complete
Turn-up process terminates.
