[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0021] The present application discloses a pipe cutting machine safety device, referring to Figure 1 、 Figure 2 and Figure 3 , comprising a base 1 for placing a pipe 10, on which a limiter 2 for limiting the rolling deviation of the pipe 10 is installed. A mounting plate 3 for mounting the pipe cutter body 4 is rotatably provided on the base 1, and the rotating shaft of the mounting plate 3 is parallel to the axis of the pipe 10. A cutting blade 41 is rotatably provided on the pipe cutter body 4, and a protective frame 5 is bolted to one end of the mounting plate 3 on the base 1. A mounting cavity for accommodating the cutting blade 41 is provided in the protective frame 5, and an avoidance opening 511 for the rotating shaft of the cutting blade 41 to pass through is provided on the side of the protective frame 5 close to the mounting plate 3. A through hole 52 for the pipe 10 to pass through is provided on the outer wall of the protective frame 5. A discharge port 11 for discharging pipe 10 debris is provided below the protective frame 5 on the base 1, and an elastic member 6 is installed on the base 1 for driving the mounting plate 3 to rotate and keep its movable end away from the pipe 10.
[0022] In the embodiment of the present application, the staff needs to first pass one end of the pipe 10 through the through hole 52, and use the limiter 2 to limit the rolling deviation of the pipe 10, then start the cutting machine body, and then rotate the mounting plate 3 to overcome the elastic force of the elastic member 6, and then move the cutting machine body so that the cutting blade 41 can cut the pipe 10. In the process of cutting the pipe 10, the debris of the pipe 10 can be discharged from the mounting cavity through the discharge port 11. A pipe cutting machine safety device of the present application, the cutting blade 41 is located in the protective frame 5, which can not only prevent the sparks generated by the steel pipe from flying onto the staff, but also prevent the staff from accidentally touching the cutting blade 41. It has the effect of improving the safety of the cutting work.
[0023] Specifically, the elastic member 6 includes a gas spring 61 , and two ends of the gas spring 61 are rotatably disposed on the mounting plate 3 and the base 1 , respectively.
[0024] Furthermore, a positioning member 7 is mounted on the mounting plate 3 to limit its rotation relative to the base 1. The positioning member 7 includes a positioning rod 71, which is slidably mounted on the mounting plate 3 along the axis of rotation of the mounting plate 3. The protective frame 5 is provided with a positioning hole 53 for receiving the positioning rod 71 when the movable end of the mounting plate 3 is away from the pipe 10.
[0025] In the embodiment of the present application, after the cutting work is completed, the worker can rotate the mounting plate 3 and align the positioning rod 71 with the positioning hole 53, and then insert the positioning rod 71 into the positioning hole 53 to limit the rotation of the mounting plate 3. This further improves the installation stability of the cutting machine body and the cutting blade 41 on the base 1.
[0026] Reference Figure 4 The stopper 2 includes two blocks 21. The base 1 is bolted to a mounting frame 8. The two blocks 21 are mounted on the mounting frame 8 so as to slide horizontally in opposite directions along the radial direction of the pipe 10. A transport channel for accommodating the pipe 10 is formed between the two blocks 21. A bidirectional screw 22 is mounted on the mounting frame 8 to drive the two blocks 21 to move in opposite directions. The two blocks 21 are respectively threadedly connected to the two threaded segments of the bidirectional screw 22, and a handle is connected to one end of the bidirectional screw 22.
[0027] In the embodiment of the present application, the staff needs to place the pipe 10 between the two blocks 21 and pass one end of it through the through hole 52. Then, by turning the handle, the two baffles can be driven to move toward each other and contact the outer wall of the pipe 10, so as to achieve the purpose of limiting the rolling deviation of the pipe 10.
[0028] Furthermore, a guide surface 211 for contacting the outer wall of the pipe 10 is provided on a side of the two stoppers 21 that is close to each other, and one end of the two guide surfaces 211 that is close to each other is higher than the other end thereof.
[0029] In the embodiment of the present application, by rotating the bidirectional screw 22, the guide surfaces 211 on the two baffles can jointly abut the outer wall of the pipe 10. Since the ends of the two guide surfaces 211 that are close to each other are higher than the other ends, the guide surfaces 211 can press down the pipe 10 when abutting the outer wall of the pipe 10, further improving the installation stability of the pipe 10 on the base 1.
[0030] Furthermore, a driving member 9 for driving the pipe 10 to vertically move up and down is vertically slidably provided on the base 1. The driving member 9 includes a top plate 91 and an electric push rod 92. The top plate 91 is vertically slidably provided on the base 1. The electric push rod 92 is installed at the bottom of the base 1. The movable end of the electric push rod 92 vertically passes through the base 1 upward and is connected to the top plate 91.
[0031] In the embodiment of the present application, the top plate 91 and the two stoppers 21 can cooperate with each other to limit pipes 10 with various outer diameters.
[0032] In order to facilitate the staff to observe the cutting of the pipe 10, the side of the protection frame 5 close to the mounting plate 3 is a transparent plate 51. The transparent plate 51 can be made of a high-temperature resistant PC board.
[0033] The implementation principle of the pipe cutting machine safety device in the embodiment of the present application is as follows: the worker must first pass one end of the pipe 10 through the through hole 52, and use the limiter 2 to limit the rolling deviation of the pipe 10, then start the cutting machine body, and then rotate the mounting plate 3 to overcome the elastic force of the elastic member 6, so that the cutting machine body can be moved so that the cutting blade 41 can cut the pipe 10. During the process of cutting the pipe 10, the debris of the pipe 10 can be discharged from the mounting cavity through the discharge port 11. The cutting blade 41 is located in the protective frame 5, which not only prevents the sparks generated by the steel pipe from flying onto the worker, but also prevents the worker from accidentally touching the cutting blade 41. This has the effect of improving the safety of the cutting work.
