[0002] A pipe beveling machine is a specialized tool for chamfering the front face of a pipe or flat plate before welding. It overcomes the shortcomings of flame cutting and grinding processes, such as irregular angles, rough surfaces, and high noise levels. It offers advantages such as ease of operation, precise angles, and smooth surfaces. Pipe beveling machines are used to bevel the weld seam during the pipeline welding process. Due to their lightweight design, they can be operated by just one person, making them suitable for workshops and construction sites.

[0003] Most of the existing cylindrical pipe beveling cutting machines have the following shortcomings:

[0005] 2. Low efficiency in groove processing: Traditional equipment often requires manual labor for multiple positioning and cutting, resulting in a lengthy and inefficient groove processing process that cannot meet the needs of fast processing.

[0006] 3. The processing environment is seriously polluted: Traditional equipment lacks a closed system, and chips and smoke can easily escape, causing pollution to the environment, and operators are easily irritated and injured.

[0007] 4. Chip handling is cumbersome: Chips collected by traditional equipment are difficult and usually require manual cleaning, which affects work efficiency and cannot achieve effective recycling of chips.

[0019] Furthermore, the working method of the cylindrical pipe cutting and beveling machine comprises the following steps:

[0020] Step 1: The beveling machine is flexibly moved by the mobile base, so that the beveling machine can be conveniently moved to one end of the cylindrical pipe, and the closing frame is covered on one end of the cylindrical pipe, and one end of the cylindrical pipe is moved into the inside of the closing frame. At this time, the two arc positioning frames are respectively on both sides of the surface of the cylindrical pipe. The two arc positioning frames are controlled by the electric slide 1 to approach the surface of the cylindrical pipe, and the supporting electric cylinder driving ends on the two arc positioning frames are controlled to contact the supporting block with the surface of the cylindrical pipe. The supporting electric cylinders on the two arc positioning frames are used to drive the supporting block to perform positioning control on one side of the end face of the cylindrical pipe.

[0021] Step 2: Inflate the sealing airbag so that it contacts the surface of the cylindrical pipe and controls the sealing between the cylindrical pipe and the closing frame.

[0022] Step 3: When performing outer bevel processing on the end face of the cylindrical pipe, first, one end of the cylindrical pipe is positioned inside the closed frame by using several positioning electric cylinder driving ends on the mounting frame, and then a servo electric cylinder driving end inside the connecting frame is controlled to drive the cutter to move to the outer end face of the cylindrical pipe, and the rotating frame is controlled to rotate, and the end face of the cylindrical pipe is subjected to outer bevel cutting processing by the rotating cutter. After one of the cutters is damaged, the cutter on the other servo electric cylinder is controlled to continue cutting the outer bevel of the end face of the cylindrical pipe. At the same time, coolant is introduced into the inside of the liquid guide ring through the liquid guide pipe, and the coolant enters the inside of the liquid guide frame through the liquid guide ring. Finally, the coolant is sprayed toward the end face of the cylindrical pipe through the spray nozzles on one side of the connecting frame, and the bevel processing of the end face of the cylindrical pipe is cooled and dusted;

[0023] Step 4: After the cylindrical pipe is positioned inside the closed frame, the rotating ring is controlled to move to the inside of the end face of the cylindrical pipe by sliding on the fixed frame. The drive ends of the servo electric cylinders are used to control the cutter to move to contact the inner wall of the cylindrical pipe. Then, the output shaft of the servo motor is combined with the meshing transmission between the drive gear and the internal tooth groove to allow the cutter to cut the inner groove of the end face of the cylindrical pipe. This allows the cylindrical pipe to be cut at the same time inside the closed frame.

[0024] Step 5. When the end face of the cylindrical pipe is beveled by the cutting mechanism, the generated cutting waste enters the interior of the collecting tank through the material guide rack. Inside the collecting tank, two relatively rotating collecting racks are used to scrape the cutting waste toward the bottom of the collecting tank. The coolant mixed with cutting dust is filtered by a filter plate, and finally the filtered coolant is sent out through a drain pipe. The collected cutting waste is scraped toward the front and back sides of the inner wall of the collecting tank by the two collecting racks, and finally the cutting waste is collected centrally by the two collection frames on the front and back sides of the frame.

[0025] The beneficial effects achieved by the present invention using the above structure are as follows:

[0026] 1. In the present invention, the beveling machine is flexibly moved by the mobile base frame, which makes it convenient to move the beveling machine to one end of the cylindrical pipe, so that the closing frame covers one end of the cylindrical pipe, and cooperates with the positioning mechanism on the top of the frame to fix and limit the surface of the cylindrical pipe, thereby ensuring the stability of the cylindrical pipe during beveling cutting. Inside the closing frame, the cutting mechanism is used to bevel one end of the cylindrical pipe, and the inner and outer bevels can be selectively processed according to one end of the cylindrical pipe. The inner and outer bevels of one end of the cylindrical pipe can be processed at one time inside the closing frame, which greatly improves the processing efficiency of the cylindrical pipe bevel. In addition, when the cylindrical pipe is beveled, the noise and smoke generated during the processing are isolated by the closing frame, which effectively reduces the pollution to the environment around the equipment during the cylindrical pipe bevel cutting process, and improves the environmental friendliness of the working operation of the beveling processing equipment.

[0027] 2. When performing groove cutting of cylindrical pipes, after moving the groove machine to one end of the cylindrical pipe, move one end of the cylindrical pipe to the inside of the closed frame. At this time, the two arc-shaped positioning frames are respectively on both sides of the surface of the cylindrical pipe. The two arc-shaped positioning frames are controlled by the electric slide to approach the surface of the cylindrical pipe. The driving end of the supporting electric cylinder on the two arc-shaped positioning frames controls the contact between the supporting block and the surface of the cylindrical pipe. The supporting electric cylinder on the two arc-shaped positioning frames drives the supporting block to position and control one side of the end face of the cylindrical pipe to ensure the stability of the cylindrical pipe during the groove cutting process.

[0028] 3. After inserting one end of the cylindrical pipe into the interior of the closing frame, the sealing airbag is inflated to allow the sealing airbag to expand and contact the surface of the cylindrical pipe. The sealing airbag is used to control the seal between the cylindrical pipe and the closing frame, so that the closing frame can play a role in sound insulation and dust isolation when the cylindrical pipe is cut.

[0029] 4. Coolant is introduced into the interior of the liquid guide ring through the liquid guide tube, and the coolant enters the interior of the liquid guide frame through the liquid guide ring. Finally, the coolant is sprayed toward the end face of the cylindrical pipe through the liquid spray nozzles on one side of the connecting frame, and the groove processing of the end face of the cylindrical pipe is cooled and dusted, thereby improving the processing quality of the groove of the end face of the cylindrical pipe and the service life of the processing tool.

[0030] 5. The generated cutting waste enters the interior of the collecting tank through the material guide rack. Inside the collecting tank, two relatively rotating collecting racks are used to scrape the cutting waste to the bottom of the collecting tank. The coolant mixed with cutting dust is filtered by the filter plate. Finally, the filtered coolant is sent out through the drain pipe. The collected cutting waste is scraped to the front and back sides of the inner wall of the collecting tank by the two collecting racks. Finally, the cutting waste is collected centrally by the two collecting frames on the front and back sides of the frame to reduce the waste of metal resources.

[0031] 6. By controlling the rotation of the rotating frame, the rotating cutter pair is used to perform outer bevel cutting on the end face of the cylindrical pipe. After one of the cutters is damaged, the cutter one on the other servo electric cylinder one is controlled to continue cutting the outer bevel of the end face of the cylindrical pipe, thereby ensuring the cutting efficiency of the outer bevel of the end face of the cylindrical pipe; through the output shaft of the servo motor combined with the meshing transmission between the drive gear and the internal tooth groove, the cutter two is allowed to cut the inner bevel of the end face of the cylindrical pipe, so that the inner and outer bevels of the cylindrical pipe can be cut at one time inside the closed frame, thereby greatly improving the bevel cutting efficiency of the cylindrical pipe.

[0057] Example 5: Specifically, this embodiment also discloses a working method of a cylindrical pipe cutting and beveling machine, comprising the following steps:

[0058] Step 1: The beveling machine is flexibly moved by the mobile base 1 to facilitate the movement of the beveling machine to one end of the cylindrical pipe, so that the closing frame 4 covers one end of the cylindrical pipe, and one end of the cylindrical pipe is moved into the inside of the closing frame 4. At this time, the two arc-shaped positioning frames 6 are respectively on both sides of the surface of the cylindrical pipe.
