[0031] Specifically, the automatic rotation system driven by the servo motor 8 and the belt 9 enables the titanium alloy tube raw material 6 to automatically rotate during the straightening process, ensuring that the tube is evenly stressed during the straightening process and improving the efficiency and accuracy of the straightening. The slide groove 10 is set to drive the slider 11, the support column 12 and the support plate 13 to move, thereby controlling the position of the pressure plate 15.

[0032] Reference Figure 1 and Figure 3 The utility model provides an embodiment: the support mechanism 16 includes a support base 1601, the top of the support base 1601 is fixedly connected to the bottom of the support frame 7, the front and rear sides of the support base 1601 are fixedly connected with cylinders 1602, the output ends of the two cylinders 1602 are fixedly connected with connecting plates 1603, the tops of the two connecting plates 1603 are fixedly connected with multiple L-shaped connecting frames 1604, the adjacent sides of the multiple L-shaped connecting frames 1604 are fixedly connected with fixed plates 1605, and the bottoms of the multiple fixed plates 1605 are slidably connected to the left and right sides of the top of the support frame 7.

[0033] Specifically, the titanium alloy tube raw material 6 is fixed by the fixing plate 1605 to ensure stability during the straightening process. The traditional fixed fixture is divided into two halves, and the cylinder 1602 drives the connecting plate 1603 and the L-shaped connecting frame 1604 to move the fixing plate 1605.

[0034] Reference Figure 1 The utility model provides an embodiment: a console 22 is fixedly connected to the front side of the base 1, a controller 21 is fixedly connected to the front side of the console 22, and a protective cover 17 is rotatably connected to the top of the controller 21; an emergency stop button 18 is fixedly connected to the front side of the console 22, and the emergency stop button 18 is arranged on the right side of the controller 21.

[0036] Working principle: Support mold 1 3 and support mold 2 5 are used to place the titanium alloy tube raw material 6 that needs to be straightened. Both sides of the titanium alloy tube raw material 6 are fixed on the support frame 7. A belt 9 is arranged inside the support frame 7. The servo motor 8 drives the belt 9 to rotate under the action of the rotating shaft 20 and the fixed shaft 19. The titanium alloy tube raw material 6 is arranged above the belt 9. Therefore, when the belt 9 is running, the titanium alloy tube raw material 6 rotates by itself, and cooperates with the top pressure plate 15 to be pushed downward by the hydraulic cylinder 3 14, so as to straighten the titanium alloy tube raw material 6. The support plate 13 on the top of the pressure plate 15 is connected to the support column 12 on both sides to support The column 12 is connected with a slider 11, and the slider 11 can move in the slide groove 10 at the bottom of the base 1, so as to control the pressure plate 15 to move to the curved part of the titanium alloy tube raw material 6 for extrusion. When facing a smaller titanium alloy tube raw material 6, the hydraulic cylinder 12 is controlled to lower the support mold 13, and the hydraulic cylinder 24 is controlled to raise the support mold 25, leaving a smaller support mold 25 to support the titanium alloy tube raw material 6. When the titanium alloy tube raw material 6 is larger, the hydraulic cylinder 12 is controlled to raise the support mold 13, and the hydraulic cylinder 24 is controlled to lower the support mold 25. At this time, the support mold 13 supports the titanium alloy tube raw material 6.

[0037] The cylinder 1602 pushes the connecting plate 1603 and the L-shaped connecting frame 1604 to move, thereby driving the fixed plate 1605 to move. There is a hole between the two fixed plates 1605 on the same side for placing the titanium alloy tube raw material 6. When the titanium alloy tube raw material 6 is small, the cylinder 1602 can be started to squeeze the two fixed plates 1605 in the middle, leaving a small gap to clamp the titanium alloy tube raw material 6. When the titanium alloy tube raw material 6 is large, the fixed plates 1605 are moved relative to each other to expand the middle gap to ensure the fixation of the titanium alloy tube raw material 6.
