Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of steel pipe processing equipment, and more specifically, to a vertical 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 should be removed, leaving a bare pipe area with a length of 100 mm to 150 mm. This is to facilitate the repair coating of the anti-corrosion layer after the steel pipes are butted and welded. The end face of the polished anti-corrosion coating should form a chamfer of 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. By manually aligning the position of the pipe end to remove the anti-corrosion coating, the pressing rod at the other end of the wire brush wheel is pressed, so that the rotating wire brush wheel contacts the polishing 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 of less than or equal to 30°. Once the chamfer is not well processed, after the repair coating of the anti-corrosion layer of the welded steel pipe is applied, the adhesion ability is reduced and it is extremely easy to fall off.

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.
[0019] As Figures 1-7 shown, a vertical pipe end beveling machine includes a loading and unloading cart 7, on which a pipe 8 is arranged. At the end of the pipe 8, a working frame 1 is cooperatively arranged. On the working frame 1, a cutting tool 3 and a positioning wheel 4 that slide up and down, and a rotatable positioning roller 62 are arranged. On one side or both sides of the pipe 8, a bench 81 is arranged. When beveling the end of the pipe 8, the cutting tool 3 is selected for cutting. The cutting tool 3 on the working frame 1 slides along the working frame 1 according to the diameter of the pipe 8, so as to meet pipes 8 of different diameters. The traditional grinding method cannot meet the beveling of pipes 8 of different diameters. During the cutting process, the cutting tool 3 can move up and down along the working frame 1 according to the angle requirement, meeting the requirement of a given degree, reducing the difficulty of beveling, improving the efficiency and accuracy; the positioning wheel 4 can slide up and down along the working frame 1 according to the diameters of different pipes 8, pressing the pipe 8 to prevent the pipe 8 from jumping up and down when the cutting tool 3 bevels the end of the pipe 8, further increasing the beveling accuracy of the pipe 8.
[0020] Through the above analysis, it can be seen that the up and down movement of the cutting tool 3 is related to the accuracy of pipes 8 of different diameters and the beveling chips. In order to accurately control the up and down movement of the cutting tool 3, a main guide rail 11, a first driving device 12 and a first driving screw 13 are arranged on the working frame 1. A main slider 22 is slidably arranged on the main guide rail 11. The main slider 22 is fixedly connected to a slide plate 21. The slide plate 21 is connected to a sliding frame 2. The cutting tool 3 is arranged on the sliding frame 2; the first driving screw 13 is rotatably arranged on the working frame 1, the first driving screw 13 is arranged parallel to the main guide rail 11, the first driving device 12 is in transmission connection with the first driving screw 13, and the first driving screw 13 is in threaded cooperation with the slide plate 21. The up and down movement of the sliding frame 2 can meet the beveling treatment of pipes 8 of different diameters.
[0021] A fixed frame 33 and a transverse frame 23 are arranged inside the sliding frame 2, and the transverse frame 23 is slidably arranged on the fixed frame 33; a fixed slideway 24 is further arranged on the fixed frame 33, and the transverse frame 23 is slidably arranged on the fixed slideway 24; a fixed power motor 25, a fixed power reducer 26, a fixed screw rod 31 and a fixed nut 32 are further arranged on the fixed frame 33, the fixed power motor 25 is in transmission connection with the fixed power reducer 26, the fixed power reducer 26 is in transmission connection with the fixed screw rod 31, the fixed screw rod 31 is in threaded transmission connection with the fixed nut 32, and the fixed nut 32 is fixedly connected with the transverse frame 23; a driving wheel 27 is in transmission connection with the output end of the fixed power reducer 26, a driven wheel 28 is coaxially fixed on the fixed screw rod 31, and a transmission belt 29 is wound between the driving wheel 27 and the driven wheel 28.
[0022] A beveling cylinder 33, a beveling guide rail 32 and a tool holder 31 are arranged on the transverse frame 23, the tool holder 31 is slidably arranged on the beveling guide rail 32, and the beveling cylinder 33 drives the tool holder 31 to move back and forth along the beveling guide rail 32. When removing the bevel angle coating of the pipe 8, it only needs to drive the tool holder 31 to move up and down when the cutting tool 3 moves horizontally. At this time, the cutting tool 3 moves up and down under the drive of the tool holder 31 to complete the processing of the established angle. Completing the processing of the bevel angle is more conducive to the processing of the surface coating after welding.
[0023] The positioning wheel 4 is connected with a positioning wheel adjusting device 5, the positioning wheel adjusting device 5 is arranged on the sliding frame 2, the positioning wheel adjusting device 5 includes an adjusting power device 51, a positioning seat 52, a positioning wheel frame 53, a positioning slider 54 and a positioning slide bar 55, the positioning wheel 4 is arranged on the positioning seat 52, and the adjusting power device 51 drives the positioning seat 52 to move up and down; the positioning wheel frame 53 is fixedly arranged on the side of the sliding frame 2 away from the working frame 1, and the adjusting power device 51 is fixedly arranged on the working frame 1; the positioning slide bar 55 is fixedly arranged on the positioning wheel frame 53, the positioning slider 54 is slidably arranged on the positioning slide bar 55, and the positioning slider 54 is fixedly connected with the positioning seat 52.

Two loading and unloading devices 71 are arranged on the loading and unloading vehicle 7, one of which has a flip plate 712 hinged on one side of the loading and unloading vehicle 7, and the other flip plate 712 is hinged on the other side of the loading and unloading vehicle 7. The flip plates 712 of the two loading and unloading devices 71 are hinged on the loading and unloading vehicle 7 at positions opposite to each other, and the steel pipe loading and unloading positions are on both sides of the loading and unloading vehicle 7. The loading and unloading vehicle 7 can load and unload pipes 8 on both sides, and each loading and unloading device 71 is matched with a stand 81, which has a wider application range and is more convenient to use.
[0027] The flip plate 712 includes a first receiving surface 221 and a second receiving surface 222, and the angle between the first receiving surface 221 and the second receiving surface 222 is less than 180°. The angle between the first receiving surface 221 and the second receiving surface 222 is generally selected to be 120°, at which time the steel pipe can be better arranged between the first receiving surface 221 and the second receiving surface 222, the pipe 8 is positioned, and the accuracy of the groove cutting is improved.
[0028] It also includes a first processing roller 73 and a second processing roller 74, which are rotatably arranged on the loading and unloading vehicle 7.
