[0002] In the welded pipe manufacturing process, the welded pipe turning mechanism is a key piece of equipment connecting welding and subsequent processes (such as cooling, flaw detection, straightening, and packaging), and its performance directly affects the efficiency and stability of the production line. With the rapid development of the welded pipe industry, downstream application fields (such as construction, petrochemicals, and machinery manufacturing) have increasingly diversified demands for welded pipes, with pipe diameters ranging from a few millimeters to several meters. The production process is also shifting from single-specification batch production to multi-specification flexible production, which places higher demands on the adaptability and automation level of the turning mechanism.

[0003] However, in the existing technology, there are many types of welded pipe turning mechanisms, such as roller conveyor type, chain type, and hydraulic turning machine. But they all have some problems. For example, when the roller conveyor type turns large diameter welded pipes, the welded pipes are heavy and the turning mechanism is prone to unstable turning. The chain type turns the chain wears out severely after long-term use, resulting in high maintenance costs. The hydraulic turning machine occupies a large area and the hydraulic system has the risk of oil leakage. Utility Model Content

[0027] The outer walls of both sets of tilting rollers 36 are fitted with anti-slip rubber sleeves 37, and the outer walls of the anti-slip rubber sleeves 37 are provided with multiple sets of annular grooves 38. The lower ends of both sets of guide rails 31 are fixed to the upper end of the processing table 1.

[0028] The specific settings and functions of this embodiment are described below. The processing table 1 serves as the basic support component of the entire mechanism. A power drive mechanism 2 and an adjustment and flipping mechanism 3 are set on its upper end. Four sets of slide grooves 14 are opened on the upper end of the processing table 1. A slider 15 is slidably installed in each set of slide grooves 14. The slider 15 is used to support and guide the movement of the movable plate 21 in the power drive mechanism 2.

[0029] The power drive mechanism 2 includes two sets of movable plates 21, four sets of transmission rods 24, two sets of reducers 22, and two sets of servo motors 23. The lower ends of the two sets of movable plates 21 are fixedly connected to the sliders 15 in the slide grooves 14 of the processing table 1, and can slide along the slide grooves 14. The reducers 22 are fixedly installed on the upper ends of the movable plates 21. One end of the reducers 22 is connected to the servo motors 23.

The other end of the two sets of transmission rods 24 is fixed to the output end of the reducer 22, thereby realizing power transmission. The outer wall of the two sets of turning rollers 36 is covered with anti-slip rubber sleeves 37. Multiple sets of annular grooves 38 are opened on the outer wall of the rubber sleeves to increase the friction between the rubber sleeves and the welded pipe, ensuring the stability of the welded pipe during the turning process.

[0031] Example 2: Figure 1 and Figure 2 As shown, a lifting mechanism 11 is installed at the lower end of the processing table 1, and an L-shaped plate 12 is fixedly installed at the upper end of the processing table 1. A photoelectric sensor 13 is fixedly installed at the top of the inside of the L-shaped plate 12. A control system 16 is installed at the front end of the lifting mechanism 11. The photoelectric sensor 13, two sets of servo motors 23 and two sets of telescopic rods 32 are all connected to the control system 16 via signals.

[0032] The overall effect of this embodiment is as follows: an L-shaped plate 12 is fixedly installed on the upper end of the processing table 1, and a photoelectric sensor 13 is set at the top of the L-shaped plate 12 to detect the position of the welded pipe. The lifting mechanism 11 installed at the lower end of the processing table 1 can adjust the height of the entire mechanism to adapt to the needs of different production scenarios. The control system 16 is installed at the front end of the lifting mechanism 11. The photoelectric sensor 13, two sets of servo motors 23 and two sets of telescopic rods 32 are all connected to the control system 16. The automatic control of each component is realized through a preset program. For example, according to the welded pipe position signal detected by the photoelectric sensor 13, the servo motors 23 are controlled to start and stop and the telescopic rods 32 are extended and retracted to realize the automatic flipping and position adjustment of the welded pipe.

[0033] The usage method and working principle of this device are as follows: First, when the welded pipe moves to the adjustment and turning mechanism through the preceding conveying equipment, the photoelectric sensor 13 installed at the top of the L-shaped plate 12 at the upper end of the processing table 1 continuously monitors the working area. Once the welded pipe enters the sensing range of the photoelectric sensor 13 and blocks the light transmission path of the sensor, the photoelectric sensor 13 immediately converts the detected signal into an electrical signal and transmits it in real time to the control system 16 located at the front end of the lifting mechanism 11.

[0034] Then, after receiving the signal, the control system 16 first judges the relevant parameters such as the specifications of the welded pipe according to the preset program (if the system has the function of automatically identifying welded pipes of different specifications, it can be analyzed based on sensor data; if manual preset is required, the operator can set the corresponding parameters in the control system 16 in advance). Subsequently, the control system 16 sends instructions to the two sets of telescopic rods 32 in the adjustment and flipping mechanism 3. The telescopic rods 32 perform telescopic movements according to the instructions. The concave rod 35 at the extended end of the telescopic rod 32 is connected to the movable plate 21. Through the telescopic movement of the telescopic rods 32, the movable plate 21 is driven to slide on the slider 15 in the slide groove 14 of the processing table 1, thereby adjusting the distance and angle of the two sets of flipping rollers 36 to adapt to the current pipe diameter and flipping requirements of the welded pipe.

[0035] After the position adjustment of the tilting roller 36 is completed, the control system 16 sends a start signal to the two sets of servo motors 23 in the power drive mechanism 2. The servo motors 23 start to run as a power source, and the high-speed rotational power output by them is transmitted to the reducer 22 connected to them. The reducer 22 reduces the power and increases the torque, and transmits the power with appropriate torque and speed to the tilting roller 36 through the transmission rod 24.

[0036] Since the outer walls of the four sets of transmission rods 24 are fixed to the inner walls of the bearing seats 34, and one end is fixed to both ends of the two sets of turning rollers 36, and the other end of the two sets of transmission rods 24 is fixed to the output end of the reducer 22, the two sets of turning rollers 36 rotate synchronously under the drive of the transmission rods 24. At the same time, the anti-slip rubber sleeve 37 and the annular groove 38 on the outer wall of the turning rollers 36 are in close contact with the surface of the welded pipe. The increased friction drives the welded pipe to turn. The two sets of servo motors 23 work together to ensure that the torque is uniform and stable during the turning process. Even when facing large-diameter, heavy welded pipes, the turning action can be carried out smoothly, avoiding jamming or asynchrony.

[0037] Finally, during the process of the rotating roller 36 driving the welded pipe to rotate, the control system 16 continuously monitors the rotation process according to the preset rotation angle parameters (such as 90°, 180°, etc.). When the welded pipe rotates close to the target angle, the control system 16 calculates the rotation based on the operating parameters of the servo motor 23 to determine whether the rotation is in place. When the preset angle is reached, the control system 16 immediately sends a stop signal to the servo motor 23, the servo motor 23 stops running, and the rotating roller 36 stops rotating, thus completing the precise rotation of the welded pipe.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
