[0001] The utility model relates to the technical field of pipe processing, in particular to a beveling machine for pipe processing. Background Art

[0002] A beveling machine is a specialized tool for chamfering the front face of pipes or flat plates 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, standard angles, and smooth surfaces. Flatbed beveling machines are categorized as portable, self-propelled, and fixed.

[0003] During the production and processing of pipe fittings, a beveling machine is required to bevel the pipe fitting ports. The beveling machine drives a scraper to bevel the pipe fitting ports. Since the pipe diameters of the pipe fittings are different, after the pipe fittings are replaced, the distance between the pipe fittings and the scraper is inconvenient to control, thereby reducing the beveling effect of the pipe fittings. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Reference Figure 1-3 A beveling machine for pipe processing includes a first mounting plate 1, a motor 2 is fixedly connected to the first mounting plate 1, a scraper 3 is fixedly connected to the output end of the motor 2, a movable frame 4 is slidably inserted into the upper end of the first mounting plate 1, a groove block 5 is fixedly connected to the bottom end of the movable frame 4, an extrusion mechanism 6 for fixing the pipe is connected to the movable frame 4, the upper end of the first mounting plate 1 is rotatably connected to the second threaded rod 7, the upper end of the movable frame 4 is provided with a second threaded hole, and the second threaded rod 7 cooperates with the second threaded hole.

[0022] Working process:

[0023] Pipe fittings of different diameters are placed on the groove block 5, and the extrusion mechanism 6 squeezes and fixes the pipe fittings on the groove block 5, and then the second threaded rod 7 is rotated. After the second threaded rod 7 is rotated, the movable frame 4 moves downward, and the movable frame 4 drives the groove block 5 to move downward. Under the cooperation of the groove block 5 and the extrusion mechanism 6, the pipe fittings are driven to move downward. After moving downward for a distance, the pipe fittings come into contact with the scraper 3 to control the distance between the pipe fitting port and the scraper 3. After the motor 2 is powered on and started, it drives the scraper 3 to rotate. After the scraper 3 rotates, the pipe fitting port is beveled to improve the effect of pipe fitting processing.

[0024] Example 2: In Example 1, when fixing the pipe fitting, it is not possible to fix the pipe fitting quickly. Figure 4As another preferred embodiment of the present invention, the difference from Example 1 is that the extrusion mechanism 6 includes a pressing plate 61, a sliding groove 62 is provided on one side of the movable frame 4, and a movable hole 63 is provided on the other side of the movable frame 4. One end of the pressing plate 61 is slidably connected to the sliding groove 62, and the other end of the pressing plate 61 passes through the movable hole 63. A first threaded hole is provided on the pressing plate 61, and the upper end of the groove block 5 is rotatably connected to the first threaded rod 64, which cooperates with the first threaded hole, and the upper end of the first threaded rod 64 is fixedly connected to a handle. When fixing the pipe fitting, the first threaded rod 64 is driven to rotate by the handle. After the first threaded rod 64 rotates, the pressing plate 61 moves downward. After moving downward for a distance, the pressing plate 61 contacts the pipe fitting and squeezes and fixes it. The pipe fitting is fixed quickly and conveniently.

[0025] Example 3: In Example 1, when the pipe is moved, the friction between the pipe and the groove block 5 is large, making it inconvenient to move the pipe. Figure 4 As another preferred embodiment of the present invention, the difference from Example 1 is that a support mechanism 8 is fixedly connected to one side of the groove block 5, and the support mechanism 8 includes two parallel second mounting plates 81, which are fixedly connected to the groove block 5. A support rod 82 is rotatably connected between the two parallel second mounting plates 81. The upper end of the support rod 82 is flush with the bottom end of the notch of the groove block 5. The second mounting plate 81 fixes the support rod 82, and the support rod 82 supports the pipe fitting. The support rod 82 is in rolling contact with the pipe fitting, thereby facilitating the movement of the pipe fitting.

[0026] Example 4: In Example 1, when the scraper 3 rotates to bevel the pipe end, the friction between the scraper 3 and the pipe end will generate debris and dust, which will be scattered into the air, reducing the air quality in the processing area. Figure 4 As another preferred embodiment of the present invention, the difference from embodiment 1 is that a dust suction mechanism 9 for processing the dust gas generated during processing is fixedly connected to the first mounting plate 1. The dust suction mechanism 9 includes a suction pump 91, which is fixedly connected to the first mounting plate 1. The inlet of the suction pump 91 is connected to a circular pipe 92 through a first connecting pipe. The circular pipe 92 is located on the outside of the scraper 3. The inner wall of the circular pipe 92 is connected to an air intake pipe 93. The outlet of the suction pump 91 is connected to a filter box 94 through a second connecting pipe. The air intake pipe 93 is provided. There are several of them distributed at equal intervals along the axis direction. After the suction pump 91 is powered on and started, suction is generated on the air inlet pipe 93. The suction on the air inlet pipe 93 sucks the dust gas, and the sucked dust gas enters the annular pipe 92. The dust gas in the annular pipe 92 is introduced into the suction pump 91 through the first connecting pipe. The suction pump 91 introduces the dust gas into the filter box 94 through the second connecting pipe. The filter box 94 filters the dust in the dust gas and releases it to prevent the dust gas from spreading into the air, thereby not reducing the air quality in the processing area.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
