Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and in particular to a bending device for the production of wastewater treatment reactors. Background Technology

[0002] As a core piece of equipment in the wastewater treatment process, the rational layout and manufacturing quality of the internal piping system of a wastewater treatment reactor directly affect its operating efficiency and treatment effect. During the production of wastewater treatment reactors, it is often necessary to bend water pipes at different angles and shapes to meet the complex fluid transport and process requirements within the reactor.

[0003] Currently, in the field of water pipe bending, most bending devices are equipped with traditional universal mandrel structures. However, traditional universal mandrels have limitations in structural flexibility and adaptability during use. For example, for water pipes requiring different bending shapes, traditional universal mandrels cannot easily adjust their structure, resulting in insufficient precision in supporting the inner wall of the pipe during bending. This can easily lead to problems such as pipe deformation and wrinkling, affecting the quality and yield of the bent pipes, and potentially reducing the sealing and stability of the internal piping system of the wastewater treatment reactor.

[0004] In addition, existing bending devices mostly rely on manual manipulation of the mandrel body for alignment and insertion when inserting and removing the universal mandrel. The operation process is cumbersome, which not only consumes manpower and time, but also presents certain difficulties in connecting with automated equipment under the trend of automated production, which is not conducive to improving production efficiency and production continuity. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a bending device for wastewater treatment reactor production, which has the advantages of adapting to different bending requirements and facilitating integration with automated equipment, thus solving some of the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a bending device for producing a wastewater treatment reactor, comprising a CNC fully automatic pipe bending machine and articulated balls. Multiple sets of articulated balls are provided, each with a hexagonal screw threaded through and connected to its center. A first articulated component is rotatably mounted on the middle of the hexagonal screw. Second articulated components are rotatably mounted on the upper and lower sides of the first articulated component on the hexagonal screw. An internally threaded tube is rotatably mounted at the middle of the rear end of the second articulated component. A threaded rod is threaded inside the internally threaded tube. A transition rod is rotatably connected to the rear end of the threaded rod. A sliding groove is provided at the middle of both the upper and lower ends of the first articulated component. The transition rod is slidably connected within the sliding groove. Internal threads are provided at both the upper and lower ends of the transition rod. Fastening bolts are threaded to both the upper and lower ends of the transition rod via these internal threads, and the fastening bolts are pressed against the first articulated component.

[0007] Furthermore, the upper end of the CNC fully automatic pipe bending machine is provided with a mandrel drive mechanism near the left side. The front end of the mandrel drive mechanism is equipped with a mandrel body, and the joint component located on the rear side is rotatably installed in the middle of the front end of the mandrel body. The mandrel is generally made of high-quality steel, and its diameter is slightly smaller than the inner diameter of the pipe. During the pipe bending process, it is inserted into the inside of the pipe to support the inner wall of the pipe and prevent the pipe from elliptical deformation or wrinkling during bending.

[0008] Furthermore, a sleeve is slidably sleeved on the outer side of the mandrel body near the front side, and a fixing frame is fixedly sleeved on the outer side of the sleeve. A T-shaped slider is fixedly connected to the lower end of the fixing frame near the front side. A sliding cavity is provided at the upper end of the CNC fully automatic pipe bending machine at the corresponding fixing frame. The T-shaped slider is slidably connected inside the sliding cavity. The T-shaped slider not only provides support but also ensures that the sleeve can move linearly, thus serving as a guide.

[0009] Furthermore, a sleeve is fixedly installed in the middle of the inner rear wall of the sliding cavity, and a sliding rod is slidably connected through the front end of the sleeve. A return spring is installed between the inside of the sleeve and the sliding rod, and the front end of the sliding rod is fixedly connected to the T-shaped slider. This simple return and rebound structure ensures the continuity and automation of the sleeve during use.

[0010] Furthermore, the CNC fully automatic pipe bending machine has a pipe bending mechanism on the left front end, a rotating mechanism on the pipe bending mechanism, and an anti-wrinkle plate fixedly installed at the rear end of the pipe bending mold of the pipe bending mechanism. The CNC fully automatic pipe bending machine also has a clamping and pushing mechanism on the right side, with the clamps on the clamping and pushing mechanism being compatible with the anti-wrinkle plate. The anti-wrinkle plate can further improve the bending quality of the water pipe.

[0011] The advantages of this utility model are as follows:

[0012] 1. This device adjusts the extension length of the threaded rod by rotating the internal threaded tube and adjusts the position of the transition rod in the slide groove by loosening the fastening bolt. It can flexibly change the spacing and bending position between adjacent joint balls, so that the joint balls rotate symmetrically with the transition rod as the center when bending, forming a flexible adjustable structure that can adapt to the pipe bending requirements of different angles. It meets the needs of preparing water pipes with various bending angles in the production wastewater treatment reactor process, provides multi-angle support inside the pipe, and improves the quality of pipe bending and the yield rate.

[0013] 2. This device houses the articulated ball assembly inside the sleeve. When inserting the universal mandrel structure into the water pipe, simply align the water pipe opening with the sleeve and push the water pipe with a little force to allow the water pipe opening to directly fit onto the outside of the articulated ball at the front end. This eliminates the need for manual mandrel alignment and insertion, making it more convenient and faster. It is also easy to interface with automated equipment, effectively eliminating the tedious manual operation process and improving production efficiency and continuity. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 A bending device for producing a wastewater treatment reactor includes a CNC fully automatic pipe bending machine 1 and articulated balls 5. Multiple sets of articulated balls 5 are connected to a hexagonal screw 6 threaded through their centers. A first articulated component 4 is rotatably mounted on the middle of the hexagonal screw 6. Second articulated components 7 are rotatably mounted on the upper and lower sides of the first articulated component 4 on the hexagonal screw 6. An internally threaded tube 8 is rotatably mounted at the middle of the rear end of the second articulated component 7. A threaded rod 9 is threaded inside the internally threaded tube 8. A transition rod 10 is rotatably connected to the rear end of the threaded rod 9. The upper and lower ends of the first articulated component 4... A groove 11 is provided in the middle, and a transition rod 10 passes through and slides between the grooves 11. Internal threads 12 are provided at both the upper and lower ends of the transition rod 10. Fastening bolts 13 are threaded to both ends of the transition rod 10 via the internal threads 12. The fastening bolts 13 abut against the joint component 4. The threaded rod 9 of this device is limited by the transition rod 10 and the groove 11. The extension length of the threaded rod 9 can be adjusted by directly rotating the internal thread tube 8, thereby changing the distance between two sets of adjacent joint balls 5. The rotatable connection between the transition rods 10 ensures better bending of the joint balls 5 during bending operations inside the water pipe. Furthermore, by loosening the fastening bolts 13, the fixing of the transition rods 10 can be released, thereby adjusting the position of the transition rods 10 within the slide groove 11. This changes the bending position of the two sets of joint balls 5 at the connection point, allowing the joint balls 5 to rotate symmetrically around the transition rods 10 as the center during bending. Simultaneously, the spacing between adjacent sets of joint balls 5 can be further adjusted, forming a flexible adjustable structure. Compared to traditional universal joint balls... The universal mandrel structure, consisting of a mandrel body 3, a ball joint 5, joint component 1 4, joint component 2 7, an internal threaded tube 8, a threaded rod 9, and a transition rod 10, can adapt to pipe bending requirements at different angles. This meets the needs of preparing water pipes with various bending angles during the production of wastewater treatment reactors. It provides multi-angle support inside the pipe. After debugging, the transition rod 10 is fixed by tightening the fastening bolts 13 to ensure stable support of the water pipe during bending, preventing pipe deformation and wrinkling, and improving the yield and quality of water pipe bends.

[0022] Please see Figures 2-3The upper end of the CNC fully automatic pipe bending machine 1 is provided with a mandrel drive mechanism 2 near the left side. The mandrel body 3 is installed at the front end of the mandrel drive mechanism 2. The joint 4 located at the rear side is rotatably installed in the middle of the front end of the mandrel body 3. The mandrel drive device usually adopts a servo motor or hydraulic system, which can accurately control the extension length and speed of the mandrel to adapt to different pipe bending process requirements.

[0023] Please see Figures 1-2 A sleeve 14 is slidably fitted onto the outer side of the mandrel body 3 near the front. A fixing frame 15 is fixedly fitted onto the outer side of the sleeve 14. A T-shaped slider 16 is fixedly connected to the lower end of the fixing frame 15 near the front. A sliding cavity 17 is provided at the upper end of the CNC fully automatic pipe bending machine 1 at the corresponding fixing frame 15. The T-shaped slider 16 is slidably connected inside the sliding cavity 17. A sleeve 18 is fixedly installed in the middle of the inner rear wall of the sliding cavity 17. A sliding rod 19 is slidably connected through the front end of the sleeve 18. A return spring is installed between the inside of the sleeve 18 and the sliding rod 19. The front end of the sliding rod 19 is fixedly connected to the T-shaped slider 16. This device can accommodate the assembly of the articulated ball 5 inside the sleeve 14. When it is necessary to insert the universal mandrel structure into the water pipe, simply align the opening of the water pipe with the sleeve 14 and push it with a little force. The water pipe moves backward, causing the sleeve 14 to move backward. During this process, the buffer spring contracts, and the slide rod 19 slides into the sleeve 18, so that the open end of the water pipe is directly fitted onto the outside of the front joint ball 5. Then, the clamping and pushing mechanism 22 and the anti-wrinkle plate 23 are engaged to clamp and position the water pipe. After running the mandrel drive mechanism 2, the universal mandrel structure can automatically enter the water pipe. Compared with the current operation of manually moving the mandrel body 3 for alignment and then inserting it into the interior, it is more convenient and faster, and it is easy to connect with automated equipment, saving the tedious process of manual operation. At the same time, the structure is simple. When the bent pipe is removed, the return spring rebounds and causes the slide rod 19 to slide out of the sleeve 18 again, driving the T-shaped slider 16 to move the sleeve 14 forward, so that the joint ball 5 and other structures can be directly retracted into the sleeve 14 for the next use.

[0024] Please see Figure 1The CNC fully automatic pipe bending machine 1 has a pipe bending mechanism 20 on the left front end, and a rotating mechanism 21 on the pipe bending mechanism 20. An anti-wrinkle plate 23 is fixedly installed at the rear end of the pipe bending mold of the pipe bending mechanism 20. A clamping and pushing mechanism 22 is set on the right side of the CNC fully automatic pipe bending machine 1. The chuck on the clamping and pushing mechanism 22 is adapted to the anti-wrinkle plate 23. After the water pipe is fixed in the pipe bending mold on the pipe bending mechanism 20 by the clamping and pushing mechanism 22 and the anti-wrinkle plate 23, the rotating mechanism 21 can be used to drive the water pipe to bend around the pipe bending mold. The technology of CNC automated pipe bending machine is relatively mature in the market. Therefore, the pipe bending mechanism 20, the rotating mechanism 21 and the clamping and pushing mechanism 22 will not be described in detail here. This technical solution focuses on optimizing the universal mandrel structure.

[0025] Working Principle: The threaded rod 9 of this device is limited by the transition rod 10 and the slide groove 11. The extension length of the threaded rod 9 can be adjusted by directly rotating the inner threaded tube 8. The rotatable connection between the threaded rod 9 and the transition rod 10 ensures better bending of the joint balls 5 when bending inside the water pipe. Furthermore, by loosening the fastening bolt 13, the fixing of the transition rod 10 can be released, thereby adjusting the position of the transition rod 10 in the slide groove 11. This changes the bending position of the two sets of joint balls 5 at the connection, allowing the joint balls 5 to rotate symmetrically around the transition rod 10 as the center during bending. Simultaneously, the spacing between adjacent sets of joint balls 5 can be further adjusted, together forming a flexible... In addition to the adjusted structure, this device can house the assembly of the articulated ball 5 inside the sleeve 14. When it is necessary to insert the universal mandrel structure into the water pipe, simply align the opening of the water pipe with the sleeve 14 and push the water pipe with a little force to move the sleeve 14 backward. During this process, the buffer spring contracts, and the slide rod 19 slides into the inside of the sleeve 18, so that the open end of the water pipe is directly fitted onto the outside of the articulated ball 5 at the front end. Then, the clamping and pushing mechanism 22 and the anti-wrinkle plate 23 are engaged to clamp and position the water pipe. After running the mandrel drive mechanism 2, the universal mandrel structure can automatically enter the inside of the water pipe. Compared with the current operation of manually moving the mandrel body 3 for alignment and insertion, it is more convenient and faster.
