[0051] Embodiment 1

[0052] like Figures 1 to 4 As shown, a pipe cutting baffle device with a purging function is used to be installed on a cutting device 100, and includes a mounting seat 1, a sliding drive mechanism, a blocking mechanism 2, a flipping drive mechanism 3 and a purging mechanism 4;

[0053] The head cutting device 100 comprises a frame 5 and a workbench 6;

[0054] The mounting seat 1 is used to be slidably connected to the frame 5 along the front-rear direction;

[0055] The sliding drive mechanism is connected to the mounting seat 1 and is used to drive the mounting seat 1 to slide forward and backward;

[0056] The blocking mechanism 2 is connected to the mounting seat 1 by flipping up and down, and has a lifting position flipped up and a blocking position flipped down. When the blocking mechanism 2 is flipped to the blocking position, it is located above the workbench 6 and is used to block the end of the pipe on the workbench 6 to position the pipe;

[0057] The flip driving mechanism 3 is installed on the mounting seat 1, connected to the blocking mechanism 2 and used to drive the blocking mechanism 2 to flip and move between the lifting position and the blocking position;

[0058] The purge mechanism 4 is connected to the blocking mechanism 2, and the purge mechanism 4 is connected to the air source and is used to blow air to the workbench 6 to purge the chips on the workbench 6. Specifically, first, the flip drive mechanism 3 drives the blocking mechanism 2 to flip to the blocking position, at which time the blocking mechanism 2 is located above the workbench 6, and when the pipe is transported forward to the position on the workbench 6, the blocking mechanism 2 blocks the end of the pipe and then positions the pipe, and then the head cutting device 100 performs head cutting on the positioned pipe. After the head cutting is completed, the flip drive mechanism 3 drives the blocking mechanism 2 to rotate to the lifting position, at which time the pipe loses the blockage and continues to be transported forward on the workbench 6. When the blocking mechanism 2 rotates to the blocking position, the purge mechanism 4 installed on the blocking mechanism 2 is connected to the air source and blows air to the workbench 6, thereby clearing the chips on the workbench 6. While clearing the chips, the sliding drive mechanism can also drive the mounting seat 1 to slide back and forth, thereby driving the blocking mechanism 2 and the purge mechanism 4 to move back and forth together, thereby clearing all the chips on the workbench 6, preventing the chips from scratching the surface of the pipe, thereby helping to improve the surface quality of the pipe. In this embodiment, the head cutting device 100 can be a pipe gang saw.

[0059] like Figures 1 to 4 As shown, the blocking mechanism 2 may include a body 7 and a blocking plate 8;

[0064] like Figures 1 to 4 As shown, the blocking mechanism 2 may further include a telescopic driving component 9;

[0065] The blocking plate 8 is slidably connected to the body 7 along the front-rear direction and is used to block the pipe;

[0066] The telescopic driving component 9 is installed on the main body 7, connected to the blocking plate 8 and used to drive the blocking plate 8 to move forward and backward; specifically, the cutting device 100 has a cutting mechanism 10, and when the main body 7 flips down to the blocking position, the telescopic driving component 9 drives the blocking plate 8 to extend so that the blocking plate 8 is closer to the cutting mechanism 10, and then the pipe is transported forward on the workbench 6, and when the front end of the pipe is against the blocking plate 8, the pipe is positioned, and the pipe can be cut by the cutting mechanism 10 at this time. After the cutting is completed, the telescopic driving component 9 drives the blocking plate 8 to retract so that the blocking plate 8 is away from the cutting mechanism 10, thereby preventing the blocking plate 8 from colliding with the cutting mechanism 10 when the main body 7 flips upward, and when the flipping driving mechanism 3 drives the main body 7 to flip upward to the lifting position, the cut pipe loses the obstruction and can continue to be transported forward. Specifically, in Figure 2 The body 7 is in the raised position. Figure 1 , 3 , 4, and 5, the body 7 is located in the blocking position.

When the blocking mechanism 2 is flipped to leave the blocking position, the position switch is untriggered, and the controller controls the solenoid valve to close. At this time, the gas is cut off to achieve automatic gas cut-off, saving compressed air energy consumption. In this embodiment, the purge pipe 11 in the purge mechanism 4 is connected to the gas source through the air guide pipeline.

[0074] like Figures 1 to 4 As shown, the flip driving mechanism 3 may include a flip hydraulic cylinder 15 and a driving arm 16;

After the head cutting is completed, the flip drive mechanism 3 drives the blocking mechanism 2 to rotate to the lifting position, at which time the pipe loses the blockage and continues to be transported forward on the workbench 6. When the blocking mechanism 2 rotates to the blocking position, the purge mechanism 4 installed on the blocking mechanism 2 is connected to the air source and blows air to the workbench 6, thereby clearing the chips on the workbench 6. While clearing the chips, the sliding drive mechanism can also drive the mounting seat 1 to slide back and forth, thereby driving the blocking mechanism 2 and the purge mechanism 4 to move back and forth together, thereby clearing all the chips on the workbench 6, preventing the chips from scratching the surface of the pipe, thereby helping to improve the surface quality of the pipe.

[0094] The purge mechanism 4 is connected to the baffle plate 8 .

[0095] like Figure 1 , 2 As shown in , 3 and 5, the blocking mechanism 2 may further include a telescopic driving component 9;

[0096] The blocking plate 8 is slidably connected to the body 7 along the front-rear direction and is used to block the pipe;

[0097] The telescopic driving component 9 is installed on the main body 7, connected to the blocking plate 8 and used to drive the blocking plate 8 to move forward and backward; specifically, the cutting device 100 has a cutting mechanism 10, and when the main body 7 flips down to the blocking position, the telescopic driving component 9 drives the blocking plate 8 to extend so that the blocking plate 8 is closer to the cutting mechanism 10, and then the pipe is transported forward on the workbench 6, and when the front end of the pipe is against the blocking plate 8, the pipe is positioned, and the pipe can be cut by the cutting mechanism 10 at this time. After the cutting is completed, the telescopic driving component 9 drives the blocking plate 8 to retract so that the blocking plate 8 is away from the cutting mechanism 10, thereby preventing the blocking plate 8 from colliding with the cutting mechanism 10 when the main body 7 flips upward, and when the flipping driving mechanism 3 drives the main body 7 to flip upward to the lifting position, the cut pipe loses the obstruction and can continue to be transported forward.

[0121] In summary, first, the flipping drive mechanism 3 drives the blocking mechanism 2 to flip to the blocking position, at which time the blocking mechanism 2 is located above the workbench 6. When the pipe is transported forward to the workbench 6, the blocking mechanism 2 blocks the end of the pipe and positions the pipe, and then the head cutting device 100 performs head cutting on the positioned pipe. After the head cutting is completed, the flipping drive mechanism 3 drives the blocking mechanism 2 to rotate to the lifting position, at which time the pipe loses the obstruction and continues to be transported forward on the workbench 6.
