Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipeline processing technology, and in particular to a local cooling device for hydraulic pipelines. Background Technology

[0002] Hydraulic steel pipes are basically divided into fluid pipes used in hydraulic systems and oil steel cylinders, also known as honed pipes. Cold-drawn or cold-rolled precision seamless steel pipes also include hydraulic steel pipes. Since these workpieces need to be bent during processing, a cooling device is required to locally cool the heated pipe body.

[0003] The existing method for local cooling of hydraulic pipelines involves workers using pliers to clamp the hydraulic pipeline after it has been heated and place it into a cooling tank for cooling. However, this manual clamping and repeated operation over a long period of time is labor-intensive and demanding, and it is impossible to accurately control the length of the local cooling process (the depth of the hydraulic pipeline into the water).

[0004] Therefore, this application proposes a local cooling device for hydraulic pipelines to solve the above-mentioned problems. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a localized cooling device for hydraulic pipelines. A drive motor rotates a lead screw, which in turn moves a slider and a lower plate downwards until the bottom of the hydraulic pipeline is partially immersed in water inside a cooling tank. This provides automatic cooling without the need for manual operation, reducing workload and allowing for precise control of the depth to which the hydraulic pipeline is submerged, ensuring accurate cooling positioning.

[0006] To solve the above-mentioned technical problems, this utility model solves the problems of manual clamping being labor-intensive, requiring a lot of time and effort, and being unable to accurately control the length of the hydraulic pipeline for local cooling through the following technical solution.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A local cooling device for a hydraulic pipeline includes a cooling tank. A fixing block is fixedly installed on the outer edge of the cooling tank. A connecting plate is rotatably installed on the outer wall of the fixing block. A frame is installed on the top of the connecting plate. A motor is fixedly installed on the top of the frame. A lead screw is fixedly connected to the power output shaft of the motor. A slider is threadedly connected to the outer edge of the lead screw. A lowering plate is fixedly installed on the outer side of the slider. A disc is installed on the side of the lowering plate away from the slider. A through hole is opened in the middle of the disc. A clamping assembly is installed on the top of the disc.

[0009] As a preferred embodiment of this utility model, the bottom of the cooling tank is equipped with three support legs, the inner bottom of the cooling tank is equipped with an arc-shaped ramp, the bottom of the cooling tank is connected to a drain pipe, and a ball valve is installed on the inner wall of the drain pipe.

[0010] As a preferred embodiment of this utility model, two nuts are symmetrically installed on the outer wall of the connecting plate, and studs are threadedly connected to the inner walls of the two nuts. A handle is installed on one outer end of the stud, and the stud is inserted into the inner wall of the fixing block and the connecting plate.

[0011] As a preferred embodiment of this utility model, the clamping assembly includes a miniature electric push rod, which is mounted on the top of the disk. The output end of the miniature electric push rod is fixedly connected to a clamping plate. There are three miniature electric push rods and three clamping plates, and the three miniature electric push rods and clamping plates are arranged in a ring on the top of the disk.

[0012] As a preferred embodiment of this utility model, a limiting rod is installed on the inner wall of the frame, and the slider is slidably installed on the outer edge of the limiting rod.

[0013] As a preferred embodiment of this utility model, a limiting ring is fixedly installed at the inner bottom of the frame, and the bottom end of the lead screw is rotatably connected to the inner wall of the limiting ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This device provides a localized cooling system for hydraulic pipelines. A drive motor rotates a lead screw, which in turn moves a slider and a lower plate downwards until the bottom of the hydraulic pipeline is partially immersed in water inside a cooling tank. This allows for automatic cooling without the need for manual operation, reducing workload and facilitating precise control of the depth to which the hydraulic pipeline is submerged, ensuring accurate cooling positioning.

[0016] This is a local cooling device for hydraulic pipelines. By opening the ball valve, the water inside the cooling tank is discharged to the outside through the drain pipe. At the same time, the curved slope can be used to ensure the timely drainage of the cooling tank and reduce residue. By turning the handle to remove the stud from the inside of the fixing block, connecting plate and nut, the connecting plate and fixing block can be separated, thereby detaching the frame from the cooling tank. This reduces the space occupied at height and facilitates transportation. Attached Figure Description

[0027] Please see Figure 1-4 A local cooling device for a hydraulic pipeline includes a cooling tank 1. A fixing block 6 is fixedly installed on the outer edge of the cooling tank 1. A connecting plate 7 is rotatably installed on the outer wall of the fixing block 6. A frame 11 is installed on the top of the connecting plate 7. A motor 12 is fixedly installed on the top of the frame 11. A lead screw 13 is fixedly connected to the power output shaft of the motor 12. A slider 14 is threadedly connected to the outer edge of the lead screw 13. A lowering plate 15 is fixedly installed on the outer side of the slider 14. A disc 16 is installed on the side of the lowering plate 15 away from the slider 14. A through hole 17 is opened through the middle of the disc 16. A clamping assembly is installed on the top of the disc 16.

[0028] See Figure 1 and Figure 4 As shown: The bottom of the cooling tank 1 is equipped with three support legs 2, and the inner bottom of the cooling tank 1 is equipped with an arc-shaped ramp 3. The bottom of the cooling tank 1 is connected to a drain pipe 4, and a ball valve 5 is installed on the inner wall of the drain pipe 4. This allows the cooling tank 1 to be stably placed on the ground using the three support legs 2, and the water inside the cooling tank 1 can be discharged to the outside through the drain pipe 4 by opening the ball valve 5. At the same time, the arc-shaped ramp 3 can ensure the timely drainage of the cooling tank 1 and reduce residue.

[0029] See Figure 2 and Figure 3 As shown: Two nuts 8 are symmetrically installed on the outer wall of the connecting plate 7. The inner walls of the two nuts 8 are threaded with studs 9. A handle 10 is installed on one end of the outer side of the stud 9. The stud 9 is inserted into the inner wall of the fixing block 6 and the connecting plate 7, so that the stud 9 can be threaded to the inner wall of the two nuts 8. This allows the fixing block 6 to be stably installed on the inner wall of the connecting plate 7, ensuring that the connecting plate 7 will not easily rotate. Conversely, after the stud 9 is removed from the inside of the fixing block 6, the connecting plate 7 and the nuts 8, the connecting plate 7 and the fixing block 6 can be separated, thereby detaching the frame 11 from the cooling tank 1, thus reducing the space occupied at high positions and facilitating transportation.

[0030] See Figure 2As shown: The clamping assembly includes a miniature electric push rod 18, which is mounted on the top of the disk 16. The output end of the miniature electric push rod 18 is fixedly connected to a clamping plate 19. There are three miniature electric push rods 18 and three clamping plates 19, and the three miniature electric push rods 18 and clamping plates 19 are arranged in a ring on the top of the disk 16. This allows the hydraulic pipe to be inserted into the inner wall of the through hole 17, and then the miniature electric push rod 18 can be driven to move the clamping plate 19 to clamp the hydraulic pipe from three different directions, ensuring that it will not easily fall onto the inner wall of the cooling tank 1 when it moves downward into the cooling tank 1 for local cooling.

[0031] See Figure 2 As shown: A limit rod 20 is installed on the inner wall of the frame 11, and the slider 14 is slidably installed on the outer edge of the limit rod 20, so that the slider 14 can be used to limit the slider 14, ensuring the stability of the slider 14 when it moves up and down on the inner wall of the frame 11, and ensuring that it will not easily deviate from its position.

[0032] See Figure 2 As shown: A limiting ring is fixedly installed on the inner bottom of the frame 11, and the bottom end of the lead screw 13 is rotatably connected to the inner wall of the limiting ring, so that the lead screw 13 can be used to limit the position of the lead screw 13 and ensure that the lead screw 13 will not easily shift or swing in position when rotating.

[0033] Working principle:

[0034] First, after heating the hydraulic pipe, use pliers to clamp the hydraulic pipe and place it on the inner wall of the through hole 17. Then, drive the miniature electric push rod 18 to move the clamping plate 19 to clamp the hydraulic pipe from three different directions. Then, drive the motor 12 to rotate the lead screw 13, which in turn drives the slider 14 and the lower plate 15 to move downward until the bottom of the hydraulic pipe is partially immersed in the water inside the cooling tank 1 for automatic cooling. This is convenient and requires no manual labor.

[0035] Then the motor 12 can be driven again to rotate the lead screw 13, which in turn drives the slider 14 and the lower plate 15 to move upward until the hydraulic pipe is removed from the interior of the cooling tank 1. Then the workers can use pliers to clamp the hydraulic pipe again for the bending process.

[0036] Finally, the ball valve 5 can be opened to discharge the water inside the cooling tank 1 to the outside through the drain pipe 4. At the same time, the curved ramp 3 can be used to ensure the timely drainage of the cooling tank 1 and reduce residue. Meanwhile, by turning the handle 10, the stud 9 can be removed from the inside of the fixing block 6, the connecting plate 7 and the nut 8, and the connecting plate 7 and the fixing block 6 can be separated, thereby detaching the frame 11 from the cooling tank 1, which can reduce the space occupied at high places and facilitate transportation.

[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
