Description

Technical Field

[0001] This utility model relates to the field of titanium tube processing technology, specifically to a titanium tube bending machine. Background Technology

[0002] Titanium is a silvery-white transition metal characterized by its light weight, high strength, metallic luster, and resistance to corrosion from moist chlorine gas. Titanium tubes are tubular materials made of titanium metal, possessing the advantages of light weight, high strength, and superior mechanical properties. Titanium tubes are widely used in heat exchange equipment, such as shell-and-tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators, and transport pipelines. Titanium tubes often require bending during processing, necessitating the use of a titanium tube bending machine.

[0003] Currently, in actual use, most of the bending components of titanium tube bending machines are fixedly connected to the machine base. This means that they can only bend titanium tubes of one size. When the size of the titanium tube changes, it is necessary to replace the bending machine or the bending components on the machine base, which is a rather troublesome process. Utility Model Content

[0004] The purpose of this invention is to provide a titanium tube bending machine to address the aforementioned shortcomings in the technology.

[0008] Two plug-in rods are provided, with their bottom ends fixedly connected to the top ends of the first and second support rods, respectively. The fixed bend plate and the fixed column are both provided with plug-in grooves in the middle. The plug-in rods pass through the plug-in grooves, and the top ends of the plug-in rods are provided with limiting components.

[0010] Preferably, a limiting frame is fixedly connected to the fixed bending plate to facilitate the limiting and fixing of the end of the titanium tube.

[0011] Preferably, the inner diameter of the limiting frame is the same as the inner diameter of the titanium tube groove on the fixed bending plate and the rotating bending plate.

[0012] Preferably, the limiting component includes a mounting cavity formed inside the top of the plug rod, a movable plate is provided inside the mounting cavity, and a limiting block is fixedly provided at the bottom outer side of the movable plate. One end of the limiting block passes through the plug rod and extends to both sides of the plug rod. One end of the limiting block is an arc surface. Multiple limiting blocks are respectively provided at the top of the fixed bend disc and the fixed column. Two movable slots are formed at the top of the plug rod, and the top of the movable plate passes through the movable slots to facilitate limiting and fixing the fixed bend disc and the fixed column.

[0013] Preferably, a fixed guide rod is fixedly provided inside the mounting cavity. The two ends of the fixed guide rod pass through the two movable plates respectively. A spring is sleeved on the outer end of the fixed guide rod.

[0014] Preferably, a push plate is fixedly provided at the top of the movable plate, and the push plate is located at the top of the plug rod to facilitate the movement of the movable plate.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By using limiting components to fix the fixed bending disc and the rotating bending disc at the top of the first and second support rods, the replacement process of the fixed bending disc and the rotating bending disc is relatively simple and convenient, with high replacement efficiency. Therefore, it can be used for bending processing of titanium tubes of different sizes, making it highly practical. Attached Figure Description

[0028] This utility model provides, for example Figures 1 to 7 The titanium tube bending machine shown includes:

[0029] Fixed base 1, with an L-shaped support platform 2 fixedly installed at the top of fixed base 1, a first support rod 3 fixedly installed at the top of one end of L-shaped support platform 2, and a fixed bent pipe disc 4 installed at the top of the first support rod 3.

[0030] Motor 5 is fixedly mounted on the top of fixed base 1. The output shaft of motor 5 is fixedly mounted with rotating rod 6. The top of rotating rod 6 is rotatably connected to the bottom of one end of L-shaped support platform 2 through bearing. Rotating plate 7 is fixedly mounted on the outer end of rotating rod 6. Fixed support plate 8 is fixedly mounted on the top of one end of rotating plate 7. Second support rod 9 is fixedly mounted on the top of fixed support plate 8. Fixed column 10 is mounted on the top of second support rod 9. Rotating bending plate 11 is rotatably connected to the outer end of fixed column 10. Titanium tube grooves are opened on the outer ends of fixed bending plate 4 and rotating bending plate 11. Limit frame 14 is fixedly connected on fixed bending plate 4. The inner diameter of limit frame 14 is the same as the inner diameter of titanium tube grooves on fixed bending plate 4 and rotating bending plate 11.

[0031] Two plug-in rods 12 are fixedly connected at their bottom ends to the top ends of the first support rod 3 and the second support rod 9, respectively. The fixed bend plate 4 and the fixed column 10 are both provided with plug-in slots 13 in the middle. The plug-in rods 12 pass through the inside of the plug-in slots 13. The top end of the plug-in rods 12 is provided with a limiting component. The cross-sections of the plug-in rods 12 and the plug-in slots 13 are both square.

[0032] The limiting assembly includes a mounting cavity 15 opened inside the top of the plug rod 12. A movable plate 17 is provided inside the mounting cavity 15. A limiting block 16 is fixedly provided on the bottom of the outer side of the movable plate 17. One end of the limiting block 16 passes through the plug rod 12 and extends to both sides of the plug rod 12. One end of the limiting block 16 is arc-shaped. Multiple limiting blocks 16 are respectively provided on the top of the fixed bend plate 4 and the fixed column 10. Two movable slots 18 are opened at the top of the plug rod 12. The top of the movable plate 17 passes through the interior of the movable slots 18. A fixed guide rod 19 is fixedly provided inside the mounting cavity 15. The two ends of the fixed guide rod 19 pass through the two movable plates 17 respectively. A spring 20 is sleeved on the outer end of the fixed guide rod 19. The two ends of the spring 20 are fixedly connected to the inner side of the two movable plates 17 respectively. A push plate 21 is fixedly provided at the top of the movable plate 17. The push plate 21 is provided at the top of the plug rod 12.

[0033] One end of the titanium tube is passed through the titanium tube groove on the fixed bending plate 4 and the rotating bending plate 11. The other end of the titanium tube is inserted into the limiting frame 14. At this time, the motor 5 is started. The output shaft of the motor 5 drives the rotating rod 6 to rotate. The rotating rod 6 drives the rotating plate 7 to rotate. The rotating plate 7 drives the fixed support plate 8 and the second support rod 9 to rotate. The second support rod 9 drives the insertion rod 12 and the fixed column 10 to rotate. The fixed column 10 drives the rotating bending plate 11 to rotate. The rotating bending plate 11 will bend the titanium tube.

[0034] Press the two push plates 21 with two fingers simultaneously to bring them closer together. The two push plates 21 drive the two movable plates 17 to move closer together. The two movable plates 17 drive the two limiting blocks 16 into the mounting cavity 15 and compress the spring 20. When one end of the limiting block 16 is flush with the outer side of the plug rod 12, the fixed bending plate 4 can be removed from the plug rod 12. Similarly, the fixed column 10 and the rotating bending plate 11 can be removed from the other plug rod 12. This allows the fixed bending plate 4 and the rotating bending plate 11 to be replaced. By opening titanium tube grooves of different sizes on the outer ends of different fixed bending plates 4 and rotating bending plates 11, different titanium tubes can be bent.

[0035] This invention uses a limiting component to fix the fixed bending disc 4 and the rotating bending disc 11 at the top of the first support rod 3 and the second support rod 9, making the replacement process of the fixed bending disc 4 and the rotating bending disc 11 simpler, more convenient, and more efficient. This allows it to be used for bending titanium tubes of different sizes, making it highly practical. Specifically, this invention solves the problem in existing titanium tube bending machines where most bending components are fixedly connected to the machine base, limiting bending to only one size of titanium tube. When the size of the titanium tube changes, the bending machine or the bending components on the machine base need to be replaced, which is a cumbersome process.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
