Technical Field

[0001] This utility model relates to the field of valve body technology, specifically to an automatic bending processing equipment for gate valve components. Background Technology

[0002] Piping systems consist of multiple components, including pipes and valves. Gate valves are one type of valve used to control the direction, pressure, and flow of fluids. They control the flow of fluids by the vertical movement of a gate and play a crucial role in piping systems. Both ends of a gate valve are usually connected to pipes to restrict the direction of the fluid.

[0003] Pipes connected to gate valves generally require different bending requirements, necessitating pipe bending. However, most pipe bending equipment is currently quite basic, only capable of bending one side of the pipe. When multiple bends are needed, it cannot be completed in one go. Furthermore, the current pipe bending process requires workers to control and hold the raw material with one hand while performing the bending operation with the other, greatly increasing the workload and posing certain dangers.

[0028] 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.

[0029] like Figure 1-4 As shown, the device includes a base 10, a fixing component, and a bending component. A hydraulic cylinder 11 and a slide rail 12 are fixedly installed on the base 10. The fixing component is movably connected within the slide rail 12, and the bending component is installed on the hydraulic cylinder 11. The hydraulic cylinder 11 is driven by hydraulic pressure.

[0030] The bending assembly includes a bending block 20, a secondary bending wheel 22, and a primary bending wheel 24. The secondary bending wheel 22 and the primary bending wheel 24 are fixed inside the bending block 20. There are two secondary bending wheels 22, which are symmetrically arranged with the primary bending wheel 24 as the center. The concave surfaces of the two secondary bending wheels 22 and the primary bending wheel 24 on the side near the slide rail 12 are on the same horizontal line. That is, when the secondary bending wheel 22 is in the arc-shaped guide groove 21 on the side away from the hydraulic cylinder 11, the secondary bending wheel 22 and the primary bending wheel 24 will not bend the pipe when they come into contact with it, keeping the middle of the pipe straight. The radius of the primary bending wheel 24 is larger than the radius of the secondary bending wheel 22, so that the secondary bending wheel 22 will not come into contact with or restrict the primary bending wheel 24 during the movement and adjustment process.

[0031] The bending block 20 is semi-circular, with one end of its arc facing the hydraulic cylinder 11. The interior of the bending block 20 is hollow. The main bending wheel 24 is located at the center of the bending block 20, and the auxiliary bending wheel 22 is located at the edge of the bending block 20. Two symmetrically arranged arc-shaped guide grooves 21 are provided on the upper surface of the bending block 20. The auxiliary bending wheel 22 slides within the arc-shaped guide grooves 21. Several limiting grooves 25 are also provided on the upper surface of the bending block 20, arranged in two symmetrical groups along the edge of the arc-shaped guide grooves 21. A bending adjustment block 23 is fitted on the auxiliary bending wheel 22 for bending adjustment. Block 23 and the secondary bending wheel 22 are limited to prevent relative rotation. The bending adjustment block 23 is connected to the secondary bending wheel 22 by a bending spring 27. A limiting block 28 is also fixed on the outer periphery of the bending adjustment block 23. The limiting block 28 corresponds to the limiting groove 25. A hydraulic rod 26 is fixed on the end face of the bending block 20 away from the slide rail 12. The hydraulic rod 26 is installed in the hydraulic cylinder 11. By pulling out the bending adjustment block 23, the position of the secondary bending wheel 22 is adjusted so that the bending angle in the middle of the pipe can be adjusted at will to adapt to different bending requirements.

[0032] At least two fixing components are provided, including a slider 30 that slides on the slide rail 12 and a fixing wheel 31. The slide rail 12 has several slots, and the slider 30 is fastened in the slots to fix the slider 30. The slider 30 has two symmetrically arranged limiting cavities inside, and a fixing adjustment block 34 is slidably arranged in the limiting cavity. The fixing adjustment block 34 is fixed to the inner wall of the limiting cavity by a fixing spring 35. The fixing adjustment block 34 is U-shaped, with one leg of the U-shape cooperating with the slot and the other leg extending to the outside. By limiting the slider 30, it can be fixed at any position on the slide rail 12.

[0033] A turntable 33 is fixed on the slider 30, and a base plate 32 is rotatably connected to the turntable 33. A fixed wheel 31 is rotatably mounted on the base plate 32. By rotating the base plate 32, it can only serve as a limit during the process of not bending the end of the pipe, without causing bending (e.g.) Figure 9As shown in the figure, there is one fixed wheel 31 on the inner slider 30 and two fixed wheels 31 symmetrically arranged on the outer slider 30. The inner fixed wheel 31 allows the pipe to be easily removed after bending, while the two outer fixed wheels 31 can restrict the position of the pipe and prevent it from slipping during bending. Moreover, the rotatable fixed wheel 31 allows the pipe to be fed during bending, so that the pipe will not be damaged due to bending.

[0034] Working principle: When in use, the pipe can be directly inserted into the two fixed wheels 31. Adjust the position of the slider 30 and the auxiliary bending wheel 22 as needed, and then the hydraulic cylinder 11 can be started. The hydraulic rod 26 drives the bending block 20 to move. At this time, the main bending wheel 24 and the auxiliary bending wheel 22 abut against the pipe. Then the hydraulic cylinder 11 continues to run, which can bend the pipe. When the hydraulic rod 26 runs to the maximum distance, the pipe bending ends. The hydraulic cylinder 11 will drive the hydraulic rod 26 and the bending block 20 to return to the reset state. At this time, the slider 30 on one side needs to be removed to remove the bent pipe.

[0035] When adjusting the position of slider 30, the fixed adjusting block 34 needs to be squeezed inward at the same time to compress the fixed spring 35, so that the fixed adjusting block 34 enters the limiting cavity. At this time, the fixed adjusting block 34 cannot be stuck in the slot, so slider 30 can be moved at will to adjust its position.

[0036] When adjusting the position of the secondary bending wheel 22, the bending adjustment block 23 needs to be pulled upward to stretch the bending spring 27, so that the limiting block 28 is released from the limitation of the limiting groove 25. At this time, it can be moved to the corresponding position along the arc-shaped guide groove 21.

[0037] like Figure 5-9 The diagram shows various bending processes of the pipe, specifically the partial bending effects of the slider 30 and the auxiliary bending wheel 22 at different positions.

[0038] In summary, this automatic bending processing equipment for gate valve components, through the arbitrary adjustment of the auxiliary bending wheel 22 and the slider 30, can adapt to most pipeline bending requirements, greatly increasing the diversity of pipeline bending; moreover, through the setting of the hydraulic cylinder 11, the pipeline can automatically complete the bending process, avoiding manual bending by workers, only requiring loading and unloading, greatly reducing the workload of workers and improving the efficiency of pipeline bending.
