[0002] In the process of chamfering the outer circle of steel pipes, a pipe end chamfering device is generally used to chamfer the steel pipes. Since a large amount of heat is generated when the tool cuts the steel pipe, a coolant is used to cool the cut portion during the chamfering process. The coolant in the existing pipe end chamfering device is generally installed near the tool in the form of a cooling pipe (wherein the cooling pipe is exposed to the outside world), and the cut portion is cooled as the tool moves. However, due to the exposure of the cooling pipe, collisions are likely to occur when the equipment moves, thereby damaging or knocking the cooling pipe crooked, and the cut portion cannot be dissipated in time. In addition, since the coolant collection frame in the existing pipe end chamfering device is located below the entire device, the coolant is prone to splashing and dirtying the workbench.

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] Example: Please refer to Figure 1-3, a pipe end chamfering device, comprising a tool 6 installed on a support frame 1 through a driving mechanism 4, a fixing mechanism 3 installed on the top of the support frame 1 and used to fix the pipe 2, and an isolation box 5 installed on a first movable plate 41 of the driving mechanism 4, the tool 6 and the end of the pipe 2 are both located inside the isolation box 5, a cooling pipe 51 connected to a liquid inlet hose 52 is fixedly connected to the top of the isolation box 5, the cooling pipe 51 runs through the isolation box 5, the liquid outlet of the cooling pipe 51 is located inside the isolation box 5 and the liquid outlet is aligned with the tool 6, the bottom of the isolation box 5 is connected to a liquid outlet hose 55, the liquid outlet hose 55 is connected to a cooling box 54, the liquid outlet pipe of the cooling box 54 is connected to a hydraulic pump 53, the liquid outlet pipe of the hydraulic pump 53 is connected to the liquid inlet hose 52, the fixing mechanism 3 and the driving mechanism 4 are connected to the top of the support frame 1 through a slide rail 12; when the hydraulic pump 53 is started , the coolant in the cooling box 54 will flow through the liquid outlet pipe, the hydraulic pump 53, the liquid inlet hose 52 and the cooling pipe 51 in sequence, and spray from the cooling pipe 51 to the tool 6, thereby taking away the heat generated by the tool 6 when chamfering the pipe material 2, and finally flow back to the cooling box 54 from the liquid outlet hose 55. In this process, since the chamfering point and the cooling pipe 51 are both located inside the isolation box 5, the cooling pipe 51 is isolated from the outside world, thereby reducing the possibility of collision when the equipment is moved, preventing the cooling pipe 51 from being damaged or distorted, thereby failing to dissipate heat at the cutting point in time; in addition, the isolation box 5 prevents the coolant from splashing, thereby improving the cleanliness of the workbench. In addition, a filter assembly 56 is provided inside the cooling box 54 to facilitate filtering of debris in the coolant and prevent damage to the hydraulic pump 53.

[0022] In this embodiment, an inclined mesh plate 510 is provided inside the isolation box 5 for preliminary filtering of chamfered debris; an inclined plate 59 is provided at the bottom of the isolation box 5 with its inclination direction toward the liquid outlet hose 55 to facilitate the coolant to converge on the liquid outlet hose 55; a through hole is provided on the isolation box 5, on which an annular rubber ring 511 is fixedly connected, and the pipe material 2 and the annular rubber ring 511 are clearance-matched to prevent the coolant from splashing out of the through hole; a rotating boss is also provided on the isolation box 5, and the rotating shaft of the tool 6 is rotatably connected to the rotating boss through a bearing 58, and an oil seal 57 cooperating with the rotating shaft is provided on the side of the rotating boss close to the interior of the isolation box 5, thereby playing a sealing role to prevent the coolant from damaging the bearing 58.

[0023] In this embodiment, the fixing mechanism 3 includes a slider 34 slidably connected to the slide rail 12, a second movable plate 36 fixedly connected to the slider 34, and a first clamping plate 31 fixedly connected to the top of the second movable plate 36. A cylinder 33 is also fixedly connected to the top of the second movable plate 36. The output end of the cylinder 33 is fixedly connected to the second clamping plate 32 for clamping the pipe material 2. When the cylinder 33 is started, the second clamping plate 32 clamps the pipe material 2. In addition, a fastening bolt 35 is also provided on the top of the slider 34. The end face of the fastening bolt 35 is in close contact with the top of the slide rail 12, which is convenient for adjusting the position of the second movable plate 36, so as to adapt to pipe materials 2 of different lengths and improve the practicality of the device. The driving mechanism 4 includes a first movable plate 41 slidably connected to the slide rail 12. A first reduction box 48 is provided on the first movable plate 41. The output end of the first reduction box 48 is connected to the tool 6. The input end is connected to the output end of the first motor 46, and the first motor 46 is fixedly connected to the top of the first reduction box 48 through the first mounting frame 47. When the first motor 46 is started, the tool 6 will rotate, thereby chamfering the pipe material 2; in addition, the driving mechanism 4 also includes a moving platform 45 fixedly connected to the bottom of the first moving plate 41, a screw 42 threadedly connected to the moving platform 45, and a second reduction box 43 installed on the second mounting frame 11, the output end of the second reduction box 43 is fixedly connected to the screw 42, and the end of the screw 42 away from the second reduction box 43 is rotatably connected to the support frame 1, and a second motor 44 is fixedly connected to the second mounting frame 11, and the output end of the second motor 44 is connected to the input end of the second reduction box 43. When the second motor 44 is started, the screw 42 will rotate, thereby driving the moving platform 45 to move, thereby realizing chamfering the pipe material 2.

[0024] How it works

[0025] When the pipe 2 needs to be chamfered, the pipe 2 is first placed on the first clamping plate 31, and then the cylinder 33 is started. The second clamping plate 32 clamps the pipe 2, and then the second motor 44 and the first motor 46 are started. When the cutter 6 rotates, the screw 42 also rotates, thereby driving the cutter 6 to move toward the pipe 2 and chamfer the pipe 2. During this process, one end of the pipe 2 will pass through the through hole into the interior of the isolation box 5, and then the hydraulic pump 53 is started, and the coolant will flow through the liquid outlet pipe, the hydraulic pump 53, the liquid inlet hose 52 and the cooling pipe 51 in sequence. And it is sprayed from the cooling pipe 51 to the tool 6, thereby taking away the heat generated by the tool 6 when chamfering the pipe material 2, and finally flows back to the cooling box 54 from the liquid outlet hose 55; therefore, since the chamfered part and the cooling pipe 51 are both located inside the isolation box 5, the cooling pipe 51 is isolated from the outside world, thereby reducing the possibility of collision when the equipment is moved, preventing the cooling pipe 51 from being damaged or distorted, thereby failing to dissipate heat at the cutting part in time; in addition, the isolation box 5 prevents the coolant from splashing, thereby improving the cleanliness of the workbench.
