Description

Technical Field

[0001] The present invention relates to the field of bevel processing for pipe openings, and specifically, to an angle-adjustable pipe bevel processing device and method. Background Art

[0002] In the modern industrial field, pipe systems are widely used in many industries such as petroleum, chemical industry, natural gas, and construction. The connection quality of pipes is directly related to the operation safety and stability of the entire system. And pipe bevel processing, as a key link before pipe connection, its accuracy and quality have a crucial impact on the effects of connection methods such as welding.

[0003] Traditional pipe bevel processing mainly relies on manual operation or simple mechanical devices, and there are many limitations. Although the manual processing method has high flexibility, it has a large labor intensity, low efficiency, and it is difficult to guarantee the processing accuracy. Differences in the technical level and experience of operators will result in inconsistent bevel angles and dimensions, thus affecting the sealing performance and mechanical properties of pipe connections. For example, in some high-pressure pipe systems with high requirements for bevel accuracy, the bevels processed manually may not meet strict engineering standards and are prone to safety hazards such as leakage.

[0004] Although some simple mechanical devices can improve the processing efficiency to a certain extent, they often lack the ability to precisely adjust the bevel angle. These devices usually can only process bevels with fixed angles and cannot meet the diverse requirements for bevel angles under different working conditions and engineering needs. For example, in complex pipe layouts, due to space limitations or special connection methods, bevels with different angles are required to achieve good docking, but the existing equipment cannot flexibly adjust the angle, restricting its application range.

[0005] In addition, some of the existing bevel processing equipment is not convenient to operate during the operation process, and the clamping, positioning, and adjustment processes of the equipment are relatively cumbersome, increasing the work burden and operation time of the operators.

[0006] With the continuous development of industrial technology, higher requirements are put forward for the quality and efficiency of pipe bevel processing. Especially in some large-scale engineering projects and high-end equipment manufacturing fields, there is an urgent need for a pipe bevel processing device and method that can precisely adjust the bevel angle, is easy to operate, and is efficient to meet the increasingly strict engineering quality standards and production requirements.

Detailed implementation manners

[0036] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustration and explanation of the present invention, and are not used to limit the present invention.

[0037] In the present invention, unless otherwise stated, the directional terms such as "up and down, left and right, front and back, inside and outside" included in the terms only represent the direction of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0038] SeeFigures 1-8 The angle-adjustable pipe beveling processing equipment shown in the figure includes a bearing table 1. Along the direction from one end to the other end on the bearing table 1, a grinding unit, a supporting unit, and a driving unit are sequentially arranged. The supporting unit is used to support the horizontally placed pipe 34 to be ground. The driving unit is used to clamp the end of the pipe 34 to be ground and drive it to rotate. The grinding unit includes a mounting frame 22 and a first cylinder 24 rotatably arranged at the lower end of the mounting frame 22. The end of the first cylinder 24 is hinged to an L-shaped plate. Both sides of the L-shaped plate are rotatably arranged at the end of the mounting frame 22 facing the pipe 34 to be ground through a pin shaft 30. A grinding motor 28 is installed on the L-shaped plate, and a grinding disc 29 is installed on the grinding motor 28.

[0039] By implementing the above technical solution, when using this processing equipment for beveling processing, first, the pipe that needs to be ground for bevel is supported by the supporting unit. Then, the first cylinder 24 is used to drive the L-shaped plate to flip the angle, adjusting the angle of the grinding disc 29 for beveling. Next, the end of the pipe is connected to the driving unit to drive the pipe to rotate. Finally, the pipe is gradually pushed to increase the grinding depth until the bevel grinding meets the process requirements. This angle-adjustable pipe beveling processing equipment and method can grind the bevel of the pipe and can grind the bevel at different angles according to the process requirements of the bevel, and the operation is convenient.

[0040] In this embodiment, in order to further provide a grinding unit, the grinding unit further includes a portal frame 21. The mounting frame 22 is vertically slidably arranged within the portal frame 21. A second cylinder 25 connecting the mounting frame 22 is installed on the portal frame 21. An extension arm 31 is arranged on the side of the mounting frame 22 facing the pipe 34 to be ground, and the pin shaft 30 is rotatably arranged on the extension arm 31. By driving the vertical movement of the mounting frame 22 by the second cylinder 25, the height position of the grinding disc 29 can be adjusted, enabling it to obtain more angles and height positions for bevel grinding.

[0041] In this embodiment, a chute 23 is arranged on the inner side of the portal frame 21, and a slider sliding in the chute 23 is arranged on the outer side of the mounting frame 22. The L-shaped plate includes a horizontal plate 27 and a vertical plate 26. The grinding motor 28 is installed on the horizontal plate 27, and a first hinge seat 35 for connecting with the cylinder rod of the first cylinder 24 is arranged on the back of the vertical plate 26. By the extension or shortening of the first cylinder 24, the L-shaped plate is driven to swing around the pin shaft 30, enabling the grinding motor 28 to obtain different angular postures, thereby adjusting the bevel grinding angle.

[0042] In this embodiment, in order to further provide a support unit, the support unit includes a sliding plate 6 that slides on the carrier table 1. A plurality of lower support seats are arranged on the sliding plate 6, and an upper pressing cover is hinged above the plurality of lower support seats. A horizontal plate is arranged in the middle of the sliding plate 6, and a lead screw nut 7 is arranged above one of the horizontal plates. A lead screw motor 8 is installed on the carrier table 1 on one side of the horizontal plate. The lead screw 9 of the lead screw motor 8 is in threaded connection with the lead screw nut 7. The sliding plate 6 is slidably connected with a track bar 3 arranged on the carrier table 1.

[0043] First, through the slidable sliding plate 6, it is convenient to push the pipeline and change the feeding depth. Specifically, by rotating the lead screw motor 8, under the guidance of the track bar 3 and the cooperation of the lead screw 9 and the lead screw nut 7, the sliding plate 6 can move forward or backward. When the pipeline needs to be placed, the upper pressing cover is flipped open to one side. When the bevel needs to be polished, the upper pressing cover is flipped to cover the pipeline.

[0044] In this embodiment, the lower support seat includes a support seat main body. Support columns 2 are detachably installed at both ends of the support seat main body, and the lower ends of the support columns 2 are fixedly connected to the sliding plate 6. The support seat main body includes a lower arc plate 5 in the middle and connecting columns 4 fixedly connected to both ends of the lower arc plate 5. The connecting columns 4 and the support columns 2 are connected by flanges. Through such a setting, the connecting columns 4 and the support columns 2 are connected by flanges to achieve detachability, so as to replace the support seat main body with different support inner diameters and process the bevels of pipelines with different diameters.

[0045] In this embodiment, a vertically penetrating through-hole is arranged on the lower arc plate 5, and a lower arc support 37 is inserted into the through-hole. Mounting plates 36 at both ends of the lower arc support 37 are connected to the connecting columns 4 by countersunk head screws 32. A plurality of lower support wheels 33 are arranged along the arc direction on the lower arc support 37. Through such a setting, the lower arc support 37 is arranged in the lower arc plate 5, and the plurality of lower support wheels 33 arranged on the lower arc support 37 directly contact the outer wall of the pipeline, providing rolling support when the pipeline rotates, thereby increasing the smoothness of the pipeline rotation. The provided detachable connection method is also convenient for later maintenance and replacement. When the lower support wheel 33 is damaged, it can also be temporarily supported by the lower arc plate 5, with high safety.

[0046] In this embodiment, the upper pressing cover includes an inverted U-shaped plate 13. A rectangular hole 14 is provided at the top of the U-shaped plate 13. Two upper pressing arms 15 are symmetrically arranged in the rectangular hole 14. An upper pressing wheel 16 is installed at the lower end of the upper pressing arm 15. The upper pressing arm 15 is connected to the side surface of the rectangular hole 14 through a spring pin. With the spring pin, in the normal state, the two opposite upper pressing arms 15 are distributed in a V-shape. When the upper pressing wheel 16 presses on the pipeline, it is elastically extruded outward to provide elastic compression on the pipeline. Of course, the outer side of the upper pressing arm 15 and the rectangular hole 14 can also be connected through an elastic rod.

[0047] In this embodiment, adjacent two U-shaped plates 13 are connected through a connecting plate 12. A second hinge seat 17 is arranged on the outer side of the U-shaped plate 13 located in the middle. A second hinge seat 10 is arranged on the same side of the sliding plate 6 as the second hinge seat 17. A third air cylinder 11 is hingedly connected between the second hinge seat 10 and the second hinge seat 17. Through such a setting, multiple U-shaped plates 13 are connected into a whole, and the multiple U-shaped plates 13 are integrally turned over or covered by the extension and shortening of the third air cylinder 11.

[0048] In this embodiment, the driving unit includes a motor frame 18 fixedly connected to the end of the sliding plate 6. A reduction motor 20 is installed on the motor frame 18. A pipe clamp 19 is installed at the shaft end of the reduction motor 20. The motor frame 18 and the reduction motor 20 move along with the movement of the sliding plate 6. The pipeline is driven to rotate by the reduction motor 20. The pipe clamp 19 can use a conventional pneumatic clamp. For example, a plurality of clamping air cylinders that expand and contract in the radial direction are arranged around the clamping surface to clamp the pipeline wall.
