For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Please refer to Figures 1 to 7 As shown, the utility model is a bending device for titanium tubes 5, including a base 1. A workbench and a support frame 3 are arranged on the base 1. The support frame 3 is located on the side of the workbench. The support frame 3 is set in an L shape. A first driving device 6 is arranged on the support frame 3. The output end of the first driving device 6 is butted with a positioning component. The first driving device 6 is located above the workbench. The titanium tube 5 is placed on the workbench. The first driving device 6 can control the positioning component to move downward until the positioning component presses on the titanium tube 5. At this time, the titanium tube 5 can be positioned.

[0028] Among them, the positioning component includes a push block 7. The push block 7 is fixedly connected to the output end of the first driving device 6. When the first driving device 6 is driven, it can drive the push block 7 to move downward, so that the push block 7 can position the titanium tube 5. An arc-shaped track groove is arranged on the lower surface of the push block 7, and the cross-section of the track groove is also arc-shaped. When the push block 7 presses on the titanium tube 5, the titanium tube 5 is located in the track groove.

[0029] A first support component 4 and a second support component 8 are arranged on the workbench, and the horizontal heights of their upper ends are flush. The positioning component is located between the first support component 4 and the second support component 8. Before the position of the titanium tube 5 is restricted by the positioning component, the titanium tube 5 is placed on the first support component 4 and the second support component 8, and the first support component 4 and the second support component 8 support the titanium tube 5.

[0030] In addition, after the titanium tube 5 is positioned, the titanium tube 5 can also be bent by the second support component 8. Specifically, the second support component 8 includes a support box, which is composed of a box shell 802 and a movable plate 801. The box shell 802 has an upper opening, and the movable plate 801 is pivotally connected to the upper opening of the box shell 802, that is, the movable plate 801 can rotate upward. At the same time, a lifting and pushing device 803 is arranged in the support box. The lifting and pushing device 803 has a vertical telescopic structure. The upper end of the lifting and pushing device 803 is connected to the movable plate 801 through an inner support frame 804. When the lifting and pushing device 803 extends, it can drive the movable plate 801 to turn upward, so that the titanium tube 5 is bent.

[0031] Specifically, the inner support 804 is set in a "T" shape, specifically including a vertical rod and a horizontal push rod. The vertical rod is perpendicularly connected to the horizontal push rod, and the connection point is located at the midpoint of the length of the horizontal push rod. At this time, the top surface of the horizontal push rod is an arc surface, and the lower end of the vertical rod is butted against the lifting and pushing device 803. When the lifting and pushing device 803 expands and contracts, it can drive the inner support 804 to move in the vertical direction. At the same time, considering that there is an interaction force between the movable plate 801 and the inner support 804 during the process of the movable plate 801 driving the titanium tube 5 to rotate upward, in order to increase the stability of the movable plate 801, an arc-shaped groove is provided on the top surface of the horizontal push rod, and a corresponding protrusion 20 is provided on the lower surface of the movable plate 801. This protrusion 20 is strip-shaped and extends along the length direction of the movable plate 801, so that the movable plate 801 can cooperate with the inner support 804; when the lifting and pushing device 803 extends, the inner support 804 can contact and cooperate with the movable plate 801, so that the movable plate 801 can be pushed to rotate upward.

[0032] In order to enable the titanium tube 5 to form two bending effects during the bending process, the workbench includes a reference table 2 and an extended table board 10. One end of the extended table board is butted against the reference table, and the other end is connected to the base through a column, and the column forms a support for the extended table board 10; a limiting component is provided on the extended table board 10, and the limiting component can slide along the length direction of the titanium tube 5 on the extended table board 10, so as to adjust the position of the limiting component relative to the titanium tube 5.

[0033] Specifically, the limiting component includes two vertical arms 9, and a limiting rod 14 is connected between the two vertical arms 9. The limiting rod 14 is located above the extended table board 10. Both vertical arms 9 pass vertically through the extended table board 10. Two strip-shaped notches are provided on the extended table board 10, and the strip-shaped notches extend along the length direction of the titanium tube 5. Each vertical arm 9 passes through the strip-shaped notch. An adjustment disk is sleeved on the vertical arm 9, and the adjustment disk is located in the strip-shaped notch. By moving the adjustment disk, the positions of the vertical arm 9 and the limiting rod 14 can be adjusted.

[0034] The adjustment disk is set as a disk with through holes, so that the two vertical arms can pass through the through holes and cooperate with the disk; at the same time, rail grooves are provided on the two opposite side walls in the strip-shaped notch, and the edge of the disk is located in the rail grooves. At this time, the disk is located between the two rail grooves, so that the disk can be located inside the extended table board 10 and can slide inside the extended table board 10, so that the vertical arm can maintain a vertical state when moving in the horizontal direction.

[0035] In order to position the opposing arm 9 in the vertical direction, an external thread is provided on the vertical arm 9, and an upper pressing plate 12 and a bottom tray 13 are screwed on through the external thread. Loosen the upper pressing plate 12 and the bottom tray 13, adjust the horizontal height of the limiting rod 14. After the horizontal height of the limiting rod 14 is adjusted, the upper pressing plate 12 can be screwed to move downward until the upper pressing plate 12 contacts the upper surface of the outer extension table plate 10. Then, control the bottom tray 13 to be screwed to move upward until the bottom tray 13 contacts the lower surface of the outer extension table plate 10. At this time, the horizontal height of the limiting rod 14 is locked;

[0036] In addition, the above-mentioned vertical arm 9 can also be set to the following structure: improve the connection structure between the bottom tray 13 and the vertical arm 9 so that the bottom tray 13 is fixed at the lower end of the vertical arm 9. At this time, the bottom tray 13 is located below the outer extension table plate 10, and a threaded hole is provided on the bottom tray 13. A locking screw 15 is screwed into this threaded hole. The locking screw 15 is parallel to the vertical arm 9. After adjusting the limiting rod 14 to the required height position, by screwing the locking screw 15, its upper end abuts against the lower surface of the outer extension table plate 10. At this time, the position of the limiting rod 14 is also locked. At this time, a spacer 16 can also be inserted between the bottom tray 13 and the outer extension table plate 10 to make the vertical arm 9 and the limiting rod 14 more stable;

[0037] Since the titanium tube 5 passes through between the two vertical arms 9 at this time and the limiting rod 14 is located above the titanium tube 5, when the movable plate 801 is turned upward to bend the titanium tube 5, the titanium tube 5 is blocked by the limiting rod 14. At this time, the movable plate 801 continues to turn upward, but the titanium tube 5 blocked by the limiting rod 14 cannot continue to move upward along the original trajectory. Therefore, the titanium tube 5 will form a bend again at the free end of the movable plate 801. In this way, through one action of turning the movable plate 801 upward, two bending effects are formed on the titanium tube 5, increasing the processing efficiency of bending the titanium tube 5;

[0038] At the same time, considering that the distance between the two bending positions on the titanium tube 5 is affected by the length of the movable plate 801, the movable plate 801 is set to have a telescopic structure, that is, the distance between the two ends of the movable plate 801 can be adjusted. Specifically as follows:

[0039] A jack is provided at the free end of the movable plate 801. The jack extends towards the pivot end of the movable plate 801. An extension arm 18 is inserted into the jack. A support arm 17 is fixed to the outer end of the extension arm 18. A threaded positioning hole 19 is provided on the lower surface of the movable plate 801. The threaded positioning hole 19 communicates with the jack. After the extension arm is pulled out or inserted by a certain length, a bolt rod can be screwed into the threaded positioning hole. The inner end of the bolt rod abuts against the extension arm. At this time, the positioning of the extension arm is formed. In order to increase the stability of the extension arm and prevent the extension arm from moving into the jack during the bending process of the titanium tube 5, a plurality of threaded positioning holes can be provided, and the plurality of threaded positioning holes extend along the length direction of the jack, thus increasing the stability of the extension arm;

[0040] To ensure that the titanium tube 5 remains relatively stable during the bending process and prevent the titanium tube 5 from shifting laterally, in the above-mentioned first support assembly 4, it includes a support platform 401. The upper surface of the support platform 401 is a flat surface. A plurality of limiting assemblies are provided on the upper surface of the support platform 401. The limiting assembly includes two limiting seats 402. The two limiting seats 402 can move towards or away from each other, so as to adjust the distance between the two limiting seats 402 and lock the distance between the two limiting seats 402. The titanium tube 5 can be placed between the two limiting seats 402, that is, the distance between the two limiting seats 402 can be the diameter of the titanium tube 5. At this time, the lateral movement of the titanium tube 5 can be avoided;

[0041] The above-mentioned limiting seat 402 is connected to the support platform 401 through two bolt vertical rods 403. The limiting seat 402 includes a bottom sliding plate and a vertical baffle. A long slot is provided on the bottom sliding plate. Both of the two bolt vertical rods 403 pass through the long slot on the bottom sliding plate, and the lower ends of the two bolt vertical rods 403 are fixed on the upper surface of the support platform 401, and the vertical baffle is fixed to the inner end of the bottom sliding plate. That is, when limiting the titanium tube 5, the vertical baffle plays a blocking role on the titanium tube 5. Then a nut 404 is screwed onto the bolt vertical rod 403. The nut 404 is located above the bottom sliding plate. When the nut 404 is tightened, it plays a role in locking and positioning the bottom sliding plate. At this time, the distance between the two limiting seats 402 is locked.

[0042] Finally, the first driving device and the lifting and pushing device adopted in this device are products such as hydraulic cylinders or electric push rods in the prior art. This application is only a basic application of their power function and telescopic function, and does not improve their structure. Therefore, the specific structure of this device will not be described in detail.
