[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A stainless steel wire bending device includes a central support platform, on which multiple large bending pins and two movable small bending pins are slidably connected.

The central support platform 1 has scale lines. Since the workpiece 100 has a symmetrical structure, it is easy to place the steel wire 200 accurately by observing the scale lines. Driven by the first drive mechanism, each large bending pin 8 moves synchronously, thereby bending the workpiece 100 into four large bending portions 101; driven by the second drive mechanism, two movable small bending pins 5 move synchronously, thereby bending the workpiece 100 into small bending portions 102 at both ends, and simultaneously forming two straight segments 103.

[0017] The first drive mechanism includes a right support platform 2 welded to the right side of the central support platform 1. A support leg 17 is installed at the bottom of the right support platform 2. A first mounting plate 16 is welded on the right support platform 2. A first hydraulic cylinder 14 is installed on the first mounting plate 16. The end of the telescopic rod of the first hydraulic cylinder 14 is connected to a first bridging drive rod 9. Specifically, a first support connecting seat 15 is welded on the first bridging drive rod 9. The end of the telescopic rod of the first hydraulic cylinder 14 is inserted into the first support connecting seat 15. The first support connecting seat 15 and the telescopic rod of the first hydraulic cylinder 14 are fixed together by bolts. The bottom of each large bending pin 8 is welded to the first bridging drive rod 9. A first through hole 7 is provided on the central support platform 1. The first bridging drive rod 9 passes through the first through hole 7. The first through hole 7 is an elongated hole. The inner wall of the first through hole 7 is slidably connected to the bending pin 8, ensuring that the large bending pin 8 can move to the right side of the fixed small bending pin 6, so that the steel wire 200 can be placed between the fixed small bending pin 6 and the large bending pin 8, and ensuring that the large bending pin 8 can move to the left side of the fixed small bending pin 6 to complete the bending operation.

[0018] The second drive mechanism includes a left support platform 3 welded to the left side of the central support platform 1. A support leg 17 is installed at the bottom of the left support platform 3. A second mounting plate 13 is welded on the left support platform 3. A second hydraulic cylinder 12 is installed on the second mounting plate 13. The end of the telescopic rod of the second hydraulic cylinder 12 is connected to a second bridging drive rod 10. Specifically, a second support connecting seat 11 is welded on the second bridging drive rod 10. The end of the telescopic rod of the second hydraulic cylinder 12 is inserted into the second support connecting seat 11. The second support connecting seat 11 and the telescopic rod of the second hydraulic cylinder 12 are fixed together by bolts. The bottoms of the two movable small bending pins 5 are welded to the second bridging drive rod 10. A second through hole 4 is provided on the central support platform 1. The second bridging drive rod 10 passes through the second through hole 4. The inner wall of the second through hole 4 is slidably connected to the movable small bending pin 5. The second through hole 4 is also an elongated hole, which ensures that the movable small bending pin 5 can move to the right side of the fixed small bending pin 6, so that the steel wire 200 can be placed between the fixed small bending pin 6 and the movable small bending pin 5, and ensures that the movable small bending pin 5 can move to the left side of the fixed small bending pin 6 to complete the bending operation.

[0019] In practical use: like Figure 1 As shown, the steel wire 200 is placed on the central support platform 1. At this time, the steel wire is located between the fixed small bending pin 6 and the large bending pin 8. The first hydraulic cylinder 14 drives its telescopic rod to extend, thereby moving the first bridging drive rod 9. The first bridging drive rod 9 moves all the large bending pins 8 together, and with the assistance of the fixed small bending pins 6, bends the steel wire 200 into the shape shown. Figure 4 As shown, the second hydraulic cylinder 12 then drives its telescopic rod to retract, thereby driving the second bridging drive rod 10 to move. The second bridging drive rod 10 drives the two movable small bending pins 5 to move to bend the two ends of the steel wire 200 as shown. Figure 5 As shown, the machining of workpiece 100 is now complete.
