[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figure 1-5 This utility model provides an embodiment of a bending device for precision alloys, comprising a base 1 and a bending table 2. A beam frame 3 is mounted above the bending table 2, and the beam frame 3 is connected to the base 1 and the bending table 2 by screws. A first mounting groove 8 is provided at the center of the bending table 2, and a die 9 is movably mounted inside the first mounting groove 8. A first hydraulic cylinder 4 is fixedly mounted above the base 1, and the telescopic end of the first hydraulic cylinder 4 is connected to the die 9 by screws. A mounting plate 11 is mounted on the top of the beam frame 3, and the mounting plate 11 is positioned above the bending table 2. A second hydraulic cylinder 6 is fixedly mounted above the beam frame 3, and the telescopic end of the second hydraulic cylinder 6 is connected to the mounting plate 9 by screws. Plate 11 is connected by screws. The lower end of the mounting plate 11 is provided with a second mounting groove 17. A punch 12 is installed below the mounting plate 11 and is slidably connected to the mounting plate 11. A sliding groove 15 is provided on the inner wall of the first mounting groove 8. There are two sliding grooves 15. A slider 16 is fixedly installed on both sides of the die 9. One end of the slider 16 extends into the interior of the sliding groove 15 and is slidably connected to the bending table 2. The cross-section of the punch 12 and the second mounting groove 17 are both T-shaped. A fastening bolt 18 is installed on the upper part of the mounting plate 11 and is threadedly connected to the mounting plate 11. The fastening bolt 18 is connected to the second mounting groove 17.
[0023] In use: Select the appropriate die 9 and install it with the first hydraulic cylinder 4 according to the alloy bending requirements. Install the punch 12 and the mounting plate 11 by fastening bolt 18. Drive the first hydraulic cylinder 4 to lift the die 9 to a suitable position, place the alloy on the die 9, and adjust the bending position of the alloy. Drive the second hydraulic cylinder 6 to drive the mounting plate 11 to descend. As the mounting plate 11 descends, the punch 12 falls down and contacts the alloy to apply pressure. The pressure causes the alloy to undergo plastic deformation, realizing the alloy bending process. After the bending is completed, drive the first hydraulic cylinder 4 to drive the die 9 to descend. The alloy bent part on the die 9 will be stuck by the first mounting groove 8, separating the alloy bent part from the die 9.

The infrared positioner assembly 14 emits infrared rays to illuminate the alloy. The bending part is adjusted by the infrared rays illuminating the alloy. The connecting rod 7 slides with the lifting and lowering of the mounting plate 11, guiding and limiting the lifting and lowering of the mounting plate 11, so that the mounting plate 11 can be lifted and lowered smoothly. The punch 12 can better bend the alloy and improve the bending accuracy of the alloy.
[0025] Please see Figure 1 and Figure 2 An electric telescopic cylinder 5 is fixedly installed above both ends of the bending table 2.
