[0020] A method for using an adjustable multi-curvature forming die device for stainless steel fastener wire: Step 1: Place the hydraulic rod 2 into the second placement groove, and insert the limiting column 26 into the positioning hole to stabilize the hydraulic rod 2, and then place the memory metal plate 21 into the forming groove. At this time, the telescopic end of the hydraulic rod 2 is extended and inserted into the second connecting sleeve 23. Then, use the first cross bolt 24 to penetrate the second internal threaded countersunk hole of the second connecting sleeve 23 and the first through hole of the hydraulic rod 2 to fix the second connecting sleeve 23 on the telescopic end of the hydraulic rod 2. Then place the first limiting plate 3 into the slide groove, and use the second cross bolt 31 to penetrate the first countersunk hole and screw it to the first threaded hole to fix the first The limiting plate 3 is fixed in the slide groove. At this time, the rear side of the first limiting plate 3 is in contact with the front side of the memory metal plate 21. Then the second limiting plate 35 is inserted into the first placement groove of the first limiting plate 3. Then, the third cross bolt 32 is rotated to drive the inserting plate 34 to be inserted into the slot of the second limiting plate 35 through the limiting ring 33, so as to limit the second limiting plate 35 in the first placement groove of the first limiting plate 3. At this time, the rear side of the second limiting plate 35 is in contact with the front side of the hydraulic rod 2, the handle 25 is located in the first avoidance groove of the second limiting plate 35, and the infusion tube of the hydraulic rod 2 is located in the second avoidance groove of the second limiting plate 35.

[0021] Step 2: Use a fixing bolt to pass through the fixing ear 16 and screw it into the threaded hole on the workbench, then put the first connecting sleeve 15 on the telescopic rod of the external hydraulic press, and open a threaded hole on the front side of the telescopic rod of the external hydraulic press, and then use a fixing bolt to pass through the second countersunk hole of the first connecting sleeve 15 and screw it into the threaded hole on the telescopic rod of the external hydraulic press to complete the installation of the device.

[0022] Step three: The multiple sets of hydraulic rods 2 in the lower mold 1 are telescopically moved, so that the telescopic end of the hydraulic rod 2 pulls the memory metal plate 21 to bend through the first cross bolt 24, the second connecting sleeve 23 and the rubber buffer pad 22, thereby changing the curvature of the memory metal plate 21. Similarly, the curvature of the memory metal plate 21 in the forming groove of the upper mold 11 can be changed by the multiple sets of hydraulic rods 2 in the upper mold 11. At this time, the stainless steel wire is placed in the forming groove of the lower mold 1, and then the upper mold 11 is driven downward by an external hydraulic press to close the mold with the lower mold 1, so that the memory metal plate 21 in the upper mold 11 presses the stainless steel wire downward on the memory metal plate 21 in the lower mold 1, thereby stamping the curvature of the stainless steel wire into the curvature of two sets of memory metal plates 21.

[0023] Step 4: When a group of hydraulic rods 2 needs to be repaired, it is only necessary to rotate the third cross bolt 32 located on the front side of the group of hydraulic rods 2 counterclockwise, so that the third cross bolt 32 can pull the insert plate 34 out of the slot of the second limit plate 35 through the limit ring 33, thereby unlocking the second limit plate 35. At this time, the second limit plate 35 can be moved forward through the easy-pull groove to separate and disassemble it from the first limit plate 3, then unscrew the first cross bolt 24 and retract the telescopic end of the hydraulic rod 2 to separate it from the second connecting sleeve 23, and then the hydraulic rod 2 can be pulled forward from the second position through the handle 25. When the second limiting plate 35 is fixed in the first placement slot of the first limiting plate 3 by the third cross bolt 32 and the insert plate 34, the movement of the first limiting plate 3 will drive the second limiting plate 35 to move synchronously.
