Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of steel pipe production, and more specifically, to a horizontal pipe end beveling machine. Background Art
[0002] After the anti-corrosion coating of the steel pipe is applied, during the on-site welding process of the steel pipe, in order to eliminate the influence of the welding heat affected zone on the anti-corrosion layer, the anti-corrosion coating at the pipe end part should be removed, and a bare pipe area with a length of 100 mm to 150 mm should be reserved to facilitate the repair coating of the anti-corrosion layer after the steel pipes are butted and welded. The chamfer angle of the polished anti-corrosion coating end face should be less than or equal to 30°. At present, the main anti-corrosion coating removal and chamfer forming devices are as follows: one is a manual operation device based on the lever principle: a wire brush wheel connected to a motor is used. The position for removing the anti-corrosion coating at the pipe end is aligned manually, and the pressure bar at the other end of the wire brush wheel is pressed to make the rotating wire brush wheel contact the grinding position. By manually controlling the magnitude of the contact force with the pipe end face, the anti-corrosion coating is removed and the chamfer is formed. Since it is difficult to control the pressure of the wire brush wheel, it is very difficult to form a chamfer angle less than or equal to 30°. Once the chamfer is not well processed, the adhesion ability of the repaired coating of the welded steel pipe will be reduced after the anti-corrosion coating is applied, and it is extremely easy to fall off. The existing beveling machines are difficult to maintain and have poor accuracy.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] As Figure 1-6 shown, a horizontal pipe end beveling machine includes a pipe rack 1, a positioning rack 2, a cutting tool 3, a bevel adjustment device 4, and a diameter adjustment device 5. A pipe 6 is arranged on the pipe rack 1, the positioning rack 2 is arranged at one end of the pipe 6, a bevel adjustment device 4 is arranged on one side of the positioning rack 2, the bevel adjustment device 4 is arranged on the diameter adjustment device 5, and the cutting tool 3 is arranged on the bevel adjustment device 4. The diameter adjustment device 5 adjusts the distance between the positioning rack 2 and the bevel adjustment device 4 according to the diameter of the pipe 6, which is equivalent to adjusting the distance between the positioning rack 2 and the cutting tool 3. The significance of this adjustment is that when the diameter of the pipe 6 changes, it is ensured that the positioning rack 2 can position the pipe 6, and the cutting tool 3 can perform beveling treatment on the pipe 6 according to requirements. At this time, with the positioning of the positioning rack 2 for the bevel, the accuracy of the bevel is improved; during the beveling process, the bevel adjustment device 4 is used to adjust the cutting tool 3, and the beveling treatment of the pipe 6 can meet the requirements such as the width and angle of the bevel, improving the accuracy and efficiency of the bevel; the cutting tool 3 is on one side of the pipe 6, which is convenient for observation during the beveling process. In case of problems, the machine can be stopped in time, and it is more convenient to replace the cutting tool 3 when it is damaged.
[0024] The bevel adjustment device 4 includes an angle adjustment device 41 and a position adjustment device 42, and the angle adjustment device 41 is arranged on the position adjustment device 42. According to the cutting of the cutting tool 3, it can be known that when the tangent of the point where the cutting tool 3 contacts the pipe 6 is perpendicular to the tool body, the cutting effect is the best. When the angle is too large or too small, cutting cannot be performed. Secondly, since the diameters of the pipes 6 are different, the distance between the cutting tool 3 and the pipe 6 needs to be adjusted. Therefore, not only the distance between the cutting tool 3 and the pipe 6 needs to be adjusted according to the diameters of different pipes 6, but also the included angle between the cutting tool 3 and the pipe 6 needs to be adjusted to prevent the cutting tool 3 from being unable to cut the coating or plating on the surface of the pipe 6 due to the diameter of the pipe 6 being too large or too small. Therefore, the angle adjustment device 41 is used to adjust the angle between the cutting tool 3 and the pipe 6, and the position adjustment device 42 is used to adjust the distance between the cutting tool 3 and the pipe 6.
