Description

Technical Field

[0001] This application relates to the field of pipe bending technology, and in particular to a pipe bending feeding device. Background Technology

[0002] Pipe fittings often require processing during use. Among these processes, bending is necessary, which requires pipe bending equipment. During the pipe bending process, a pipe feeding device is needed to work with the bending structure to transport the pipe fittings, ensuring continuous processing.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist:

[0004] Firstly, some existing pipe bending devices directly feed the pipe into the clamping mechanism. However, this method may result in improper or unstable clamping due to poor precision, which will reduce the processing effect of the pipe in subsequent processing.

[0005] Secondly, most existing pipe bending devices use robotic arms to transport pipes, but in some smaller areas, some robotic arms may not be able to operate, which reduces the efficiency of pipe delivery.

[0006] To address the aforementioned problems, the inventors have proposed a pipe bending and feeding device to solve these issues. Utility Model Content

A circular ring is provided inside the rotating ring and fixedly installed in the middle of one side of the vertical plate. Multiple clamping blocks are slidably inserted into the outer surface of one side of the circular ring. The opposite ends of the clamping blocks are all in contact with the grooves. By using the electric push rod, the rotating ring can be driven to rotate, causing the rotating ring to squeeze the multiple clamping blocks to move towards the center, thereby positioning the pipe and improving accuracy.

[0019] 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.

[0020] Example: Figure 1-4 As shown, this utility model provides a pipe bending and feeding device, including a plate 1. An auxiliary clamping mechanism 2 is fixedly installed on one side of the upper surface of the plate 1. The auxiliary clamping mechanism 2 can initially position the pipe and prevent displacement during clamping. A feeding mechanism 3 is fixedly installed on the other side of the upper surface of the plate 1. The feeding mechanism 3 can feed the pipe into the auxiliary clamping mechanism 2. The auxiliary clamping mechanism 2 includes a vertical plate 21, which is fixedly installed on one side of the upper surface of the plate 1. An mounting member 28 is fixedly installed on the lower part of the vertical plate 21 and on the top surface of the plate 1. The mounting member 28 can fix the vertical plate 21 to the top of the plate 1 and prevent the vertical plate 21 from falling off. A through groove 27 is opened in the middle of the vertical plate 21, which allows the pipe to enter the auxiliary clamping mechanism 2. An electric push rod 25 is rotatably installed on the top of the vertical plate 21. The electric push rod 25 can be adjusted in direction during use. A rotating ring 22 is rotatably installed at the telescopic end of the electric push rod 25, which can drive the rotating ring 22 to rotate. The rotating ring 22 is rotatably installed in the middle of one side of the upright plate 21, so that the rotating ring 22 can rotate on the upright plate 21. Multiple grooves 26 are opened on the inner wall of the rotating ring 22. The grooves 26 are used to cooperate with the subsequent clamping blocks 23. A circular ring 24 is set inside the rotating ring 22. The outer surface of the circular ring 24 is in contact with the inner surface of the rotating ring 22. The circular ring 24 is fixedly installed in the middle of one side of the upright plate 21 and will not rotate. Multiple clamping blocks 23 are slidably inserted into the outer surface of one side of the circular ring 24. The clamping blocks 23 can position the pipe. The multiple clamping blocks 23 are arranged in a circular array, which can make the positioning more accurate. The opposite ends of the clamping blocks 23 are in contact with the grooves 26, so that the clamping blocks 23 can enter the grooves 26 to achieve the effect of releasing the pipe.

[0021] The feeding mechanism 3 includes a support plate 30. A feed trough 32 is fixedly installed on one side of the upper surface of the support plate 30. The feed trough 32 can conveniently store pipe fittings. The upper part of the feed trough 32 is inclined to allow the pipe fittings to enter the device better. A servo cylinder 33 is provided on one side of the feed trough 32. The servo cylinder 33 is fixedly installed inside the support plate 30 to prevent the servo cylinder 33 from shaking during use. A top plate 31 is fixedly installed on the output end of the servo cylinder 33, which can drive the top plate 31 to rise and fall. The upper part of the top plate 31 has an arc-shaped groove that cooperates with the pipe body. The arc-shaped groove can conveniently place pipe fittings and prevent the pipe fittings from rolling. Limit rods 34 are fixedly installed on both sides of the lower surface of the top plate 31, and the bottom end of the limit rod 34 is slidably inserted into the upper surface of the support plate 30. The limit rods 34 can make the rising and falling of the top plate 31 more stable. The other side of the top surface of the support plate 30 A bracket 37 is fixedly installed on the side. A through square groove 38 is opened on the upper surface of the bracket 37, so that the servo cylinder 33 can drive the pipe to rise onto the bracket 37 through the top plate 31. A servo motor 35 is fixedly installed on one side of the upper surface of the bracket 37. A threaded rod 36 is fixedly installed on the output end of the servo motor 35. The servo motor 35 can drive the threaded rod 36 to rotate. A movable plate 39 is threaded on the outer surface of the threaded rod 36, so that the threaded rod 36 drives the movable plate 39 to move. A sliding rod 361 is fixedly installed on one side of the top surface of the bracket 37, and the sliding rod 361 is slidably inserted into the movable plate 39. The sliding rod 361 can make the movable plate 39 more stable when moving. A push plate 391 is fixedly installed on the lower surface of one side of the movable plate 39, so that the movable plate 39 drives the push plate 391 to move. The push plate 391 extends into the square groove 38, so that the push plate 391 can push the pipe into the auxiliary clamping mechanism 2.

[0022] Working principle: First, the auxiliary clamping mechanism 2 is installed on the plate 1 via the mounting part 28. The plate 1 is then installed in a suitable location, with the auxiliary clamping mechanism 2 positioned behind the clamping device. The pipe to be bent is then placed sequentially into the feed trough 32, where it rolls until it enters the arc-shaped groove on the top plate 31. The arc-shaped groove restricts the pipe. Then, the servo cylinder 33 is activated, causing the top plate 31 to rise, which in turn causes the pipe to rise. Simultaneously, the top plate 31 rises more stably via the limit rod 34. When the top plate 31 carries the pipe through the square groove 38 to the bracket 37, the servo motor 35 is activated. The servo motor 35 drives the threaded rod 36 to rotate, causing the threaded rod 36 to move the moving plate 39. The moving plate 39 then slides on the sliding rod 361, simultaneously moving the push plate 391 to push the pipe from the rear into the through groove 27 of the vertical plate 21.

[0023] Then, start the electric push rod 25 to pull the rotating ring 22 to rotate. The clamping block 23 will disengage from the groove 26 and be squeezed by the inner wall of the rotating ring 22, causing the clamping block 23 to slide on the ring 24 and move towards the center, positioning the pipe inside the through groove 27. Then, the clamping device on the processing device can be used to fix the pipe, thereby improving the accuracy.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
