Description

Technical Field

[0001] This utility model belongs to the field of hydraulic oil pipe technology, and in particular relates to a welding hydraulic oil pipe cleaning device. Background Technology

[0002] A hydraulic press is a device that works using hydraulic principles. It has a variety of functions and applications, mainly including: forming and processing, compression molding, powder metallurgy, metal heat treatment, straightening and shaping, mold making, pressure testing, composite material manufacturing, metal extrusion, packaging and compaction, forging, assembly and disassembly, etc. Due to its powerful pressure and precise control capabilities, hydraulic presses play an important role in industrial production.

[0003] Hydraulic pipelines play a crucial role in the hydraulic system of a hydraulic press. Their main functions can be summarized as follows: transmitting media, transmitting power, maintaining pressure, system layout, system protection, ease of maintenance, connecting various components, and regulating flow and pressure. In short, hydraulic pipelines are an indispensable part of the hydraulic system; they not only transmit power and media but also significantly impact the system's efficiency, safety, and maintainability.

[0004] Hydraulic pipelines typically consist of multiple straight and curved pipes connected together. These straight and curved pipes are joined together using pipe fittings. Therefore, welding issues are always encountered during the installation of hydraulic pipelines. Hydraulic pipelines are usually constructed from seamless steel pipes made of 20 steel. Over time, slag inclusions and corrosion can accumulate inside the pipelines (especially at the weld joints), affecting the cleanliness of the oil circuit.

[0005] The current production process is as follows: welding oil pipes (elbows, flanges, etc.) - pickling - water washing and air drying - high-pressure oil gun rinsing - assembly; due to the complexity of the pipeline, pickling always results in incomplete cleaning, with irregular rust marks still appearing on the inner wall, and welding slag spatter, etc., which poses a risk of contaminating the hydraulic oil circuit. Utility Model Content

[0006] The purpose of this utility model is to provide a welding hydraulic oil pipe cleaning device to grind the inside of the oil pipe after pickling, and remove stubborn rust and welding slag.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: a welding hydraulic oil pipe cleaning device, comprising a cleaning unit, a rotating unit, and a traction unit; the cleaning unit is used to clean the inside of the hydraulic oil pipe, and the cleaning unit can generate pressure with the inner wall of the hydraulic oil pipe; the rotating unit includes a rotating drive component and a transmission assembly, the transmission assembly includes a rotating flexible shaft and a traction flexible shaft, the traction flexible shaft has a rotating chamber along its length, the rotating flexible shaft is located in the rotating chamber and can rotate in the rotating chamber; both ends of the traction flexible shaft are rotatably connected to the rotating flexible shaft; one end of the rotating flexible shaft is connected to the driving end of the rotating drive component, and the other end is connected to the cleaning unit; the traction unit is used to traction the traction flexible shaft.

[0008] Furthermore, the traction unit includes a fixed base, a traction drive component, a first roller, and a second roller. Two sets of rotating shafts are rotatably connected to the fixed base. The first roller and the second roller are respectively fixed on the two sets of rotating shafts. The traction drive component is fixed on the fixed base, and the driving end of the traction drive component is fixed to one of the sets of rotating shafts. The first roller and the second roller are arranged side by side, and the traction flexible shaft can pass between the first roller and the second roller. There is friction between the first roller, the second roller, and the traction flexible shaft.

[0009] Furthermore, the cleaning unit includes a wire brush head, the outer diameter of which is larger than the inner diameter of the hydraulic oil pipe when not subjected to external force; the wire brush head is fixed to the rotating flexible shaft.

[0010] Furthermore, the fixing base includes a support plate, a base plate, a first C-shaped mounting bracket, and a second C-shaped mounting bracket. The support plate supports the base plate. The first C-shaped mounting bracket and the second C-shaped mounting bracket are mounted on the base plate with their openings facing each other. The two sets of rotating shafts are rotatably connected within the first C-shaped mounting bracket and the second C-shaped mounting bracket, respectively. The first C-shaped mounting bracket has a through hole, and a mounting plate is fixed on the first C-shaped mounting bracket. The traction drive component is fixed on the mounting plate, and the drive end of the traction drive component is connected to the corresponding rotating shaft through the through hole.

[0011] Furthermore, the drive end of the traction drive component is connected to the rotating shaft via a coupling, and the coupling can pass through the through hole.

[0012] Furthermore, the second C-shaped mounting bracket is slidably connected to the base plate, and the second C-shaped mounting bracket can slide towards or away from the first C-shaped mounting bracket. The second C-shaped mounting bracket is provided with a locking member for fixing the second C-shaped mounting bracket.

[0013] Furthermore, a threaded hole is provided on the support plate near the second C-type mounting bracket. The locking member is a threaded member, which is threadedly connected to the threaded hole. One end of the locking member is rotatably connected to the second C-type mounting bracket.

[0014] Furthermore, the first and second rollers are rubber rollers, and the traction flexible shaft is a rubber sleeve.

[0015] Furthermore, the cleaning unit is detachably connected to the rotating flexible shaft.

[0016] The working principle of this technical solution is as follows: The traction flexible shaft is inserted into the pickled hydraulic oil pipe after passing through the first and second rollers until it extends from the other end of the pickled hydraulic oil pipe, fixing the wire brush head onto the rotating flexible shaft. Then, the locking component is rotated, causing the second C-shaped mounting bracket to move towards the first C-shaped mounting bracket until the first and second rollers press the traction flexible shaft together, generating friction. Then, the rotating drive and traction drive are activated. The rotating drive drives the rotating flexible shaft to rotate, which in turn drives the wire brush head to rotate. The traction drive drives the first roller to rotate, and due to friction, the traction flexible shaft also moves, thus causing the wire brush head to rotate and move simultaneously. The wire brush head deforms after being positioned behind the hydraulic oil pipe, generating pressure inside the pipe, thereby polishing the pickled hydraulic oil pipe. After polishing, the hydraulic oil pipe needs to be washed with water to remove the pickling liquid, rust, and polished residue, and then air-dried. Finally, the pipeline is flushed with a high-pressure oil gun.

[0017] The beneficial effects of this technical solution are as follows:

[0018] ①The wire brush head contact grinding method in this technical solution can remove stubborn stains, rust, welding slag and other debris from inside the hydraulic oil pipe, thereby improving the cleanliness of the hydraulic oil pipe.

[0019] ② This technical solution uses a rotating flexible shaft and a traction flexible shaft, which can deform to adapt to the shape of the hydraulic oil pipe.

[0020] ③ In this technical solution, the cleaning unit and the rotating flexible shaft are detachably connected, and different wire brush heads can be replaced according to the inner diameter of the hydraulic oil pipe.

[0021] ④ In this technical solution, the second C-type mounting bracket is slidably connected to the base plate and is equipped with a locking device to facilitate the loading and unloading of the traction flexible shaft. It can also adapt to different traction flexible shafts. Attached Figure Description

[0030] The rotating unit includes a rotating drive component 3 and a transmission assembly 2, such as Figure 4 As shown, the transmission assembly 2 includes a rotating flexible shaft 10 and a traction flexible shaft 11. The traction flexible shaft 11 has a rotating chamber along its length. The rotating flexible shaft 10 is located within the rotating chamber and can rotate within it.

One end of the rotating flexible shaft 10 is connected to the drive end of the rotating drive component 3, and the other end is detachably connected to the wire brush head 4, specifically using screws.

[0031] like Figure 1-3As shown, the traction unit is used to traction the traction flexible shaft 11. The traction unit includes a fixed base 5, a traction drive component 6, a first roller 7, and a second roller 8. The first roller 7 and the second roller 8 are rubber rollers, and the traction flexible shaft 11 is fitted with a rubber sleeve. The fixed base 5 includes a support plate 13, a base plate 14, a first C-shaped mounting bracket 15, and a second C-shaped mounting bracket 16. The support plate 13 supports the base plate 14. The first C-shaped mounting bracket 15 and the second C-shaped mounting bracket 16 are mounted on the base plate 14 with their openings facing each other. The second C-shaped mounting bracket 16 is slidably connected to the base plate 14 and can slide towards or away from the first C-shaped mounting bracket 15. The second C-shaped mounting bracket 16 is equipped with a locking member 12, which is used to fix the second C-shaped mounting bracket 16. Specifically, the support plate 13 near the second C-shaped mounting bracket 16 has a threaded hole. The locking member 12 is a threaded part, and the locking member 12 is threadedly connected to the threaded hole. One end of the locking member 12 is rotatably connected to the second C-shaped mounting bracket 16. Two sets of rotating shafts 9 are respectively rotatably connected in the first C-shaped mounting bracket 15 and the second C-shaped mounting bracket 16. The first C-shaped mounting bracket 15 has a through hole, and a mounting plate 17 is fixed on the first C-shaped mounting bracket 15. The traction drive member 6 is fixed on the mounting plate 17.

Due to friction, the traction flexible shaft 11 also moves, so the wire brush head 4 rotates and moves simultaneously. The wire brush head 4 deforms after being positioned behind the hydraulic oil pipe 1, generating pressure inside the hydraulic oil pipe 1, thereby polishing the pickled hydraulic oil pipe 1. After grinding, hydraulic oil pipe 1 needs to be washed with water to remove pickling liquid, rust, and grinding residue, and then air-dried. Finally, the pipeline is flushed with a high-pressure oil gun.
