Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural equipment technology, specifically to a horizontal pipe end beveling device. Background Technology
[0002] After the anti-corrosion coating is applied to the steel pipe, during on-site welding, to eliminate the influence of the heat-affected zone on the anti-corrosion layer, the anti-corrosion coating at the pipe end should be removed, leaving a 100mm-150mm bare pipe area to facilitate recoating after butt welding. The ground anti-corrosion coating end face should form a chamfer of less than or equal to 30°. Currently, the main anti-corrosion layer removal and chamfering devices used are: 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 layer at the pipe end is manually aligned, and the pressure rod at the other end of the wire brush wheel is pressed, causing the rotating wire brush wheel to contact the grinding position. The contact force with the pipe end face is manually controlled to remove the anti-corrosion layer and form the chamfer. Due to the difficulty in controlling the pressure of the wire brush wheel, it is difficult to form a chamfer of less than or equal to 30°. If the chamfer is not handled well, the adhesion of the anti-corrosion layer after welding is reduced, and it is very easy to fall off.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0030] like Figure 1-6 As shown, a horizontal pipe end beveling device includes a pipe frame 1, a positioning frame 2, a cutter 3, a beveling adjustment device 4, and a diameter adjustment device 5. A pipe 6 is mounted on the pipe frame 1, the positioning frame 2 is mounted on one end of the pipe 6, the beveling adjustment device 4 is mounted on one side of the positioning frame 2, the beveling adjustment device 4 is mounted on the diameter adjustment device 5, and the cutter 3 is mounted on the beveling adjustment device 4. The diameter adjustment device 5 adjusts the distance between the positioning frame 2 and the beveling adjustment device 4 according to the diameter of the pipe 6. This is equivalent to adjusting the distance between the positioning frame 2 and the cutter 3. The significance of this adjustment is that when the diameter of the pipe 6 changes, it ensures that the positioning frame 2 can position the pipe 6, and the cutter 3 can perform beveling on the pipe 6 as required. At this time, the beveling is positioned by the positioning frame 2, and the beveling accuracy is improved. During the beveling process, the beveling adjustment device 4 is used to adjust the cutter 3, so that the beveling of the pipe 6 can meet the requirements of the beveling width, angle, etc., improving the beveling accuracy and efficiency. The cutter 3 is on one side of the pipe 6, which makes it easy to observe during the beveling process. If a problem occurs, the machine can be stopped in time, and it is more convenient to replace the cutter 3 when it is damaged.
[0031] The bevel adjustment device 4 includes an angle adjustment device 41 and a position adjustment device 42, with the angle adjustment device 41 mounted on the position adjustment device 42. Based on the cutting distance of the cutter 3, the best cutting effect is achieved when the tangent at the point of contact between the cutter 3 and the pipe 6 is perpendicular to the blade. Cutting is impossible when the angle is too large or too small. Furthermore, the distance between the cutter 3 and the pipe 6 needs to be adjusted depending on the pipe 6's diameter. Therefore, it is necessary not only to adjust the distance between the cutter 3 and the pipe 6 according to different pipe 6 diameters, but also to adjust the included angle between them to prevent the cutter 3 from failing to cut the plating or coating on the pipe 6 surface if the pipe 6's diameter is too large or too small. Thus, the angle adjustment device 41 is used to adjust the angle between the cutter 3 and the pipe 6, and the position adjustment device 42 is used to adjust the distance between the cutter 3 and the pipe 6.

When the swing frame 411 swings, the angle between the cutter 3 and the tube 6 can be adjusted to meet the cutting requirements.
[0033] The cutter pressure plate 413 is L-shaped, with one side of the cutter pressure plate 413 mounted on the first movable frame 412.

When the swing power device 414 extends or retracts, the first swing column 4151, the second swing column 4152, and the third swing column 4153 apply a pushing or pulling force to the swing groove 4111 on the swing frame 411, thereby realizing the swing of the swing frame 411.
