Description of the reference numerals:

the die comprises a female die 1, a female die holder 2, a male die 3, a male die holder 4, a blank holder 5, a guide sleeve 6, a guide pillar 7, a spring 8, a first screw 9, a cylindrical pin 10, a lifting ring screw 11 and a second screw 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-7, the cold drawing deep die for the pure titanium interior trim cover-shaped sheet metal part on the airplane comprises a female die 1, a male die 3, a female die holder 2 and a male die holder 4, wherein the female die holder 2 is connected with an upper platform of a press machine and is fixed; the female die 1 is connected to the female die holder 2 through the butt joint positioning effect of the cylindrical pin 10 and the fastening effect of the second screw 12; the convex die holder 4 is connected with the lower platform of the press and is fixed; the male die 3 is connected to the male die holder 4 through the butt joint positioning function of the cylindrical pin 10 and the fastening function of the second screw 12;

a blank holder 5 capable of moving up and down is arranged outside the male die 3, a plurality of first screws 9 are connected to the male die base 4, and the male die base 4 and the blank holder 5 are in positioning connection through the first screws 9; a spring 8 is assembled on the first screw 9, and the spring 8 is positioned between the blank holder 5 and the convex die holder 4; the male die 3 and the blank holder 5 are not fixed, the blank holder 5 can move up and down according to the stroke size of the first screw 9, when the male die 3 and the female die 1 are not matched, the spring 8 is in a loose state without compression, when the male die 3 and the female die 1 are matched, the spring 8 is tightly pressed, the compression is generated, elastic force is generated, and after the parts are matched, when the female die 1 is upward, the spring 8 releases the elastic force to push the blank holder 5 to unload.

A plurality of groups of guide sleeves 6 and guide pillars 7 for butt joint and guiding are arranged between the male die holder 4 and the female die holder 2, the guide sleeves 6 are fixedly arranged on the male die holder 4, and the guide pillars 7 are fixedly arranged on the female die holder 2; the guide sleeve 6 and the guide post 7 play a role in butt joint and guide between the male die and the female die 1;

the outer sides of the male die holder 4 and the female die holder 2 are respectively provided with a plurality of lifting bolts 11, and the lifting bolts 11 play a role in assembling and disassembling the die.

The working principle is as follows:

the die is assembled and installed on a press, and the punch-die base 2 is connected with the upper platform and the lower platform of the press respectively and is fixed. The next blank is placed on the blankholder 5 with the edge of the blank aligned with the edge of the blankholder 5. The upper platform of the press machine drives the female die 1 to move downwards, and when the female die 1 is contacted with the blank holder 5

And the female die 1 continues to move downwards, the blank holder 5 generates blank holding force at the moment, the materials around the blank are dragged to be free from generating wrinkles, and when the male die 3 and the female die 1 are closed, the part forming is finished. The female die 1 moves upwards, the spring 8 releases elasticity to push the blank holder 5 to move upwards, and the part loosens and falls off.
