specific Embodiment approach 1
[0018] Specific implementation mode one: combine figure 1 Describe this embodiment, this embodiment comprises punch 1, blank holder ring 2, sealing ring 3, coil 4 and die 5, and the upper end surface of described die 5 is provided with die cavity 5-1 and The binder ring groove 5-2, the bottom surface of the binder ring groove 5-2 is provided with an annular coil groove 5-2-1, the coil 4 is arranged in the annular coil groove 5-2-1, the inner side wall of the binder ring 2 There is an annular sealing ring groove 2-2, the punch of the punch 1 is a round table 1-1, the tail of the punch 1 is a cylinder 1-2, the blank holder 2 is set on the cylinder 1-2, and the blank holder There is a liquid channel 6 between the inner wall of 2 and the cylinder 1-2, the sealing ring 3 is set on the cylinder 1-2 and arranged in the annular sealing ring groove 3-1, and the side wall of the blank holder 2 is provided with an upward The liquid passage 2-1, the side wall of the die 5 is provided wi...
specific Embodiment approach 2
[0019] Specific implementation mode two: combination figure 1 To illustrate this embodiment, the upper liquid inlet channel 2-1 and the lower liquid channel 6-1 of this embodiment are arranged facing each other up and down. Other connection relationships are the same as those in the first embodiment.
specific Embodiment approach 3
[0020] Specific implementation mode three: combination figure 1 Describe this implementation mode, this implementation mode is realized through the following steps:
[0021] Step 1. Place the composite sheet 7 on the bottom surface of the blankholder groove 5-2, and move the blankholder 2 down to a place where the lower end surface of the blankholder 2 is 0.5mm to 2mm away from the upper end surface of the composite sheet 7. Blankholder 2 applies blankholder force F BH 5kN~200kN;
[0022] Step 2. The punch 1 moves down to the upper surface of the composite sheet 7, and at the same time, the positive liquid is applied to the liquid channel 6 from the upper liquid channel 2-1, and its positive liquid pressure P 1 2MPa~50MPa, the reverse liquid is applied from the lower liquid inlet channel 5-3 to the die cavity 5-1, and its reverse liquid pressure P 2 Should be greater than 1.5 times the positive liquid pressure P 1 , less than 100MPa (that is, 100MPa≥P 2 ≥P 1 ), then the...
