Description

Technical Field

[0001] This invention relates to the field of manifold processing technology, specifically to a manifold bending device. Background Technology

[0002] Pipe bending is an important step in pipe processing, especially metal pipe processing. After the pipe is formed, it is difficult for users to achieve a good bending effect. Therefore, professional bending equipment is generally required to bend the pipe. Diverter pipes are a common type of metal pipe. They are generally characterized by a small diameter and usually need to be used in conjunction with other pipes. Bending them is inconvenient, and existing bending tools have relatively fixed bending angle settings, resulting in poor applicability. Therefore, we propose a diverter pipe bending device. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a shunt pipe bending device, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a shunt pipe bending device, comprising a processing table, a top mounting groove on the top of the processing table, a pre-tightening fixing mechanism inside the top mounting groove, a fixing block fixedly mounted on the top of the processing table, a bottom mounting frame fixedly mounted at the bottom of the processing table and below the fixing block, a bending mechanism inside the processing table and the bottom mounting frame, the bending mechanism comprising two first servo motors, both of which are fixedly mounted at the bottom of the bottom mounting frame, a first connecting shaft fixedly mounted at the output end of the first servo motors, the first connecting shaft passing through the fixing block and rotatably connected to it, two arc-shaped sliding grooves inside the processing table, a second connecting shaft slidably mounted inside each of the two arc-shaped sliding grooves, a bending drive block fixedly mounted on the outer side of the first connecting shaft, one side of the bending drive block being fixedly connected to the outer side of the second connecting shaft, and a bending fixture fixedly mounted on the outer side of the second connecting shaft and above the processing table.

A second servo motor is fixedly installed on one side of the slide table, and the output end of the second servo motor is fixedly connected to one end of the lead screw. A slider is slidably connected inside the slide table, and the lead screw passes through the slider and is threadedly connected to it. A connecting block is fixedly installed on one side of the slider, and a movable clamping block is fixedly installed on one side of the connecting block. The movable clamping block cooperates with the fixed block, and the fixing mechanism facilitates the fixing of the pipe to be bent.

[0006] Preferably, the bottom of the processing table is fixedly installed with four base support frames in a rectangular array, which increases the stability of the processing table.

[0007] Preferably, the bottom of the bending fixture near the fixed block and the bottom of the outer side of the fixed block are both provided with arc-shaped grooves, so that the contact area between the pipe to be bent and the fixed block and the bending fixture is larger and the placement is more stable.

[0008] Preferably, the center of the arc-shaped groove is on the same axis as the center of the first connecting shaft.

[0009] Preferably, two guide sliders are fixedly installed at the bottom of the movable clamping block, and two guide grooves are opened at the top of the processing table.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0014] Please see Figures 1 to 6 This invention provides a technical solution: a shunt pipe bending device, including a processing table 1, a top mounting groove 2 on the top of the processing table 1, a pre-tightening fixing mechanism inside the top mounting groove 2, a fixing block 9 fixedly mounted on the top of the processing table 1, and a bottom mounting frame 3 fixedly mounted at the bottom of the processing table 1 and below the fixing block 9. A bending mechanism is provided inside the processing table 1 and the bottom mounting frame 3, and the bending mechanism includes two first servo motors 4, both of which are fixedly mounted at the bottom of the bottom mounting frame 3. The output of the first servo motors 4... A first connecting shaft 5 is fixedly installed at the end, passing through the fixed block 9 and rotatably connected to it. Two arc-shaped slides 10 are opened inside the processing table 1. The center of the arc-shaped slides 10 and the center of the first connecting shaft 5 are located on the same axis. A second connecting shaft 7 is slidably installed inside both arc-shaped slides 10. A bending drive block 6 is fixedly installed on the outside of the first connecting shaft 5. One side of the bending drive block 6 is fixedly connected to the outside of the second connecting shaft 7. A bending fixture 8 is fixedly installed on the outside of the second connecting shaft 7 and above the processing table 1.

[0015] The pre-tightening fixing mechanism includes a slide table 11, which is fixedly installed inside the top mounting groove 2. A lead screw 13 is rotatably installed inside the slide table 11. A second servo motor 12 is fixedly installed on one side of the slide table 11. The output end of the second servo motor 12 is fixedly connected to one end of the lead screw 13. A slider 14 is slidably connected inside the slide table 11. The lead screw 13 passes through the slider 14 and is threadedly connected to it. A connecting block 15 is fixedly installed on one side of the slider 14. A movable clamping block 16 is fixedly installed on one side of the connecting block 15. Two guide sliders 17 are fixedly installed at the bottom of the movable clamping block 16. Two guide grooves 18 are opened on the top of the processing table 1. The guide sliders 17 are inserted into the guide grooves 18 and slidably connected to them, which increases the stability of the movable clamping block 16 when sliding on the top of the processing table 1. The movable clamping block 16 cooperates with the fixed block 9, and the fixing mechanism facilitates the fixing of the pipe to be bent.

[0016] The bottom of the processing table 1 is fixedly equipped with four bottom support frames 19 in a rectangular array, which increases the stability of the processing table 1. The bottom of the bending fixture 8 near the fixed block 9 and the bottom of the outer side of the fixed block 9 are both provided with arc-shaped grooves, which makes the contact area between the pipe to be bent and the fixed block 9 and the bending fixture 8 larger and the placement more stable.

[0017] In summary, when using this shunt pipe bending device, the pipe to be bent is first placed on the side of the fixed block 9 near the movable clamping block 16, and in contact with the bending fixture 8. Then, the second servo motor 12 is started using an external controller, which drives the lead screw 13 to rotate, causing the slider 14 to slide inside the slide table 11 towards the side near the fixed block 9. At this time, the movable clamping block 16 contacts the pipe to be bent, thus clamping the pipe. Subsequently, the two first servo motors 4 are started using the external controller, so that the first servo motors 4 can drive the bending drive block 6 to rotate via the first connecting shaft 5. At the same time, the second connecting shaft 5... Shaft 7 slides inside the arc-shaped groove 10, simultaneously driving the bending fixture 8 to squeeze the pipe, thereby bending the pipe. The bending angle can be adjusted by using an external controller to adjust the rotation angle of the output end of the first servo motor 4. In this case, only one first servo motor 4 can be started to perform unilateral bending, or the rotation angles of the output ends of the two first servo motors 4 can be set to different values ​​to achieve bending at different angles on both sides. After the bending is completed, the first servo motor 4 and the second servo motor 12 are controlled again to make the moving clamping block 16 and the bending fixture 8 return to their initial positions, so that the bent pipe can be taken out for subsequent use.
