Description

Technical Field

[0001] This application belongs to the technical field of beveling equipment, specifically relating to a beveling machine. Background Technology

[0002] Marine piping systems contain numerous metal pipes. The ends of these pipes, as well as those connecting to fittings, require beveling to create a slope that facilitates welding between pipes and / or fittings. Beveling machines are commonly used for this process; however, existing beveling machines are not well-suited for non-straight pipes, and direct processing can result in low-precision beveling, negatively impacting subsequent welding quality. Summary of the Invention

[0003] To address the technical problem that existing beveling machines are not well-suited for non-straight pipes, and that direct processing leads to low beveling accuracy, which affects the quality of subsequent welding, this application provides a beveling machine.

[0005] A clamping assembly is disposed on the base, the clamping assembly having at least three jaws to jointly clamp a first end of the pipe;

[0006] A limiting component is disposed on the base or the clamping component, the limiting component being operablely sleeved on the second end of the pipe, the first end of the pipe and the second end of the pipe having an included angle;

[0007] A cutting tool assembly, disposed on the base, is used to cut the first end portion of the pipe.

[0008] In some embodiments, when the limiting component is fitted onto the second end of the pipe, the axis of the second end of the pipe is located in the same vertical plane as the axis of the first end of the pipe.

[0009] In some embodiments, the limiting component is a pipe clamp, one side of the outer wall of the pipe clamp is disposed on the base, and the two ends of the pipe clamp are detachably connected in a ring shape by bolts.

[0010] In some embodiments, the inner wall of the clamp is provided with a first buffer pad.

[0011] In some embodiments, the base is in the shape of a cylindrical tube, and the tool assembly is disposed within the base;

[0012] The tool assembly includes a drive unit and a tool head that is pulsatorically connected to the drive unit. The drive unit is capable of driving the tool head to rotate axially about the base.

[0013] In some embodiments, the clamping assembly includes:

[0014] A radial slide rail is fixed and coaxially disposed on the base. The radial slide rail is provided with at least three radial strip holes, which are spaced apart around the axis of the radial slide rail.

[0015] An involute slide rail is coaxially arranged with the base and can rotate around the axis of the base. The involute slide rail is provided with at least three involute holes, which are spaced apart around the involute slide rail. The radial strip holes correspond one-to-one with the involute holes.

[0016] A guide is provided for each pair of radial strip holes and involute holes. The guide is slidably engaged with both the radial strip holes and the involute holes. When the involute slide rail rotates clockwise or counterclockwise, the guide will move closer to or further away from the axis of the base along the radial strip holes.

[0017] Each of the guide members is fixedly connected to a clamp, and at least three of the clamps can jointly clamp the first end of the pipe.

[0018] In some embodiments, the end of the gripper facing the axis of the base is provided with an arc surface.

Detailed Implementation

[0030] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] This application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Please see Figures 1-5According to a first aspect of this application, a beveling machine is provided for beveling curved pipes. The beveling machine includes a base 100, a clamping assembly 200, a limiting assembly 300, and a cutting tool assembly 400. The pipe 500 has a first end 510 and a second end 520, and the first end 510 and the second end 520 of the pipe 500 form an angle, that is, the angle between the axis of the first end 510 of the pipe 500 and the axis of the second end 520 of the pipe 500 is less than 180°.

[0033] The clamping assembly 200 is disposed on the base 100. The clamping assembly 200 has at least three jaws 240 to jointly clamp the first end 510 of the pipe 500 so that the position of the first end 510 of the pipe 500 relative to the base 100 remains unchanged. The end of the first end 510 of the pipe 500 is the part that needs to be beveled.

[0034] A limiting component 300 is disposed on the base 100 or the clamping component 200, and the limiting component 300 is operable to sleeve the second end 520 of the pipe 500; a cutting tool assembly 400 is disposed on the base 100 to cut the end of the first end 510 of the pipe 500, so that the end of the first end 510 of the pipe 500 forms a bevel.

[0035] This application uses a clamping assembly 200 and a limiting assembly 300 to jointly restrict the first end 510 and the second end 520 of the pipe 500. This ensures that the pipe 500 remains stationary when the cutting tool assembly 400 is machining the first end 510, thereby reducing the possibility of the pipe 500 shaking during cutting. This improves the accuracy of the cutting tool assembly 400 in machining the first end 510 of the pipe 500, increases the accuracy of the beveling of the pipe 500, and improves the yield. Of course, without using the limiting assembly 300, the beveling machine in this application can also be used for beveling straight pipes, demonstrating high adaptability.

[0036] In some embodiments, when the limiting component 300 is sleeved on the second end 520 of the pipe 500, the axis of the second end 520 of the pipe 500 and the axis of the first end 510 of the pipe 500 are located in the same vertical plane. When the clamping assembly 200 clamps the first end 510 of the pipe 500, the limiting assembly 300 is located below or above the first end 510 of the pipe 500. After being clamped and limited by the clamping assembly 200 and the limiting assembly 300, the central axis of the first end 510 and the second end 520 of the pipe 500 are located on the same vertical plane. It can be understood that for a structure with a relatively regular shape like the pipe 500, the projection of the center of gravity of the pipe 500 on the horizontal plane will fall on the axis of the pipe 500 at the first end 510. The pipe 500 is less likely to rotate relative to the base 100 due to the weight of the second end 520. This is beneficial for the tool assembly 400 to process the pipe 500, reduces the possibility of low beveling quality due to displacement of the pipe 500, and improves the yield of the pipe 500 processed by the beveling machine.

[0037] In some embodiments, the limiting component 300 is a pipe clamp, with one outer wall of the clamp disposed on the base 100. The two ends of the clamp are detachably connected in a ring shape by bolts. The pipe clamp may include a clamp body, a connector, and bolts. The clamp body is a flexible metal sheet that can be bent. The connector is disposed on the outer wall of the flexible metal sheet, and the flexible metal sheet is installed on the base 100 through the connector. The two ends of the flexible metal sheet are bent outwards to form connecting plates. Each connecting plate is provided with a screw hole, and two connecting plates can be connected together by bolts. The distance between the two connecting plates can be adjusted according to the length of the bolts to accommodate pipes 500 of different sizes. Of course, the connecting plates can also be provided with through holes. The bolts and nuts are used. By adjusting the position of the nuts on the bolts, under the restoring force of the flexible metal sheet after being bent, one connecting plate abuts against the nut of the bolt, and the other connecting plate abuts against the nut, which can also complete the limiting of the second end 520 of the pipe 500 by the pipe clamp.

[0038] In some embodiments, a first buffer pad is provided on the inner wall of the pipe clamp. The first buffer pad can be made of a deformable material such as rubber or sponge. The first buffer pad increases the contact area with the pipe 500, reduces hard contact, and avoids scratching the pipe wall of the pipe 500.

[0039] In some embodiments, the limiting component 300 is a limiting rope. One end of the limiting rope is fixedly connected to the base 100, and the other end of the limiting rope is detachably connected to the base 100. By adjusting the position of the connection between the other end of the limiting rope and the base 100, the size of the limiting rope and the pipe 500 that can be fitted can be changed, resulting in high adaptability and low cost.

[0040] In some embodiments, the base 100 is cylindrical, and the tool assembly 400 is disposed within the base 100. The tool assembly 400 includes a drive member 410 and a cutter head 420 pulverically connected to the drive member 410. The drive member 410 is capable of driving the cutter head 420 to rotate about the axial direction of the base 100 and to move the cutter head 420 closer to or away from the pipe 500. The tool assembly 400 is disposed within the cylindrical base 100, thereby protecting the tool assembly 400 and reducing external impacts. The base 100 has an axis, and the pipe 500, which is stationary relative to the base 100, is beveled by rotating the cutter head 420.

[0041] In some embodiments, the clamping assembly 200 includes a radial slide plate 210, an involute slide plate 220, a guide 230, and at least three grippers 240.

[0042] The radial slide rail 210 is fixed and coaxially mounted on the base 100. The radial slide rail 210 is provided with at least three radial slots 211, which are spaced apart around the axis of the radial slide rail 210. The radial slots 211 are slots arranged radially along the length of the radial slide rail 210.

[0043] The involute slide rail 220 is coaxially arranged with the base 100 and can rotate around the axis of the base 100. The involute slide rail 220 is provided with at least three involute holes 221, which are spaced apart around the involute slide rail 220. The radial strip holes 211 correspond one-to-one with the involute holes 221. The involute holes 221 are arc-shaped and have a first end 510 close to the axis of the involute slide rail 220 and a second end 520 away from the axis of the involute slide rail 220.

[0044] Each pair of radial slots 211 and involute holes 221 is fitted with a guide member 230. The guide member 230 is slidably engaged with both the radial slots 211 and the involute holes 221. When the involute slide rail 220 rotates clockwise or counterclockwise, the guide member 230, which is slidably engaged with the involute holes 221, is restricted by the radial slots 211 and can only move along the length of the radial slots 211, thus moving closer to or away from the axis of the involute slide rail 220. The guide member 230 will move closer to or away from the axis of the base 100 along the radial slots 211. Each guide member 230 is fixedly connected to a gripper 240, and at least three grippers 240 can jointly hold the first end 510 of the pipe 500.

[0045] The groove wall of the involute hole 221 not only pushes the guide member 230 to move, but also forms an angle with the groove wall of the radial strip hole 211. When the involute slide rail 220 and the radial slide rail 210 remain relatively stationary, the groove walls of the involute hole 221 and the radial strip hole 211 will jointly restrict the guide member 230, so that the guide member 230 can be stably set in the radial strip hole 211 and the involute hole 221. Of course, a protruding ridge parallel to the radial strip hole 211 can also be provided on the radial slide rail 210, and an internal threaded hole communicating with the radial strip hole 211 can be provided on the protruding ridge. By rotating the screw 212 threadedly connected to the internal threaded hole, the screw 212 abuts against the guide member 230, which can also fix the guide member 230, so as to fix the position of the clamp 240.

[0046] Of course, both the slide rail plate and the involute slide rail plate 220 are provided with through holes in the middle that are coaxial with the axis of the base 100, so that the pipe 500 can extend into the base 100 and contact the tool assembly 400.

[0047] In some embodiments, the end of the gripper 240 facing the axis of the base 100 is provided with an arc surface 241 to accommodate the arc surface 241 of the pipe 500.

[0048] Considering that the beveling machine can process pipes 500 of different diameters, in some embodiments, a second buffer pad is provided at one end of the gripper 240 facing the axis of the base 100. By providing the second buffer pad, the end face of the gripper 240 facing the pipe 500 can be adapted to pipes 500 of different diameters, which not only increases the contact area and friction, but also prevents scratching the outer wall of the pipe 500.

[0049] In some embodiments, at least three jaws 240 are equally spaced to improve the stability when clamping the pipe 500. For example, the clamping assembly 200 has three jaws 240 with an included angle of 120 degrees between them, and there are three radial strip holes 211 and three involute holes 221. Alternatively, the clamping assembly 200 may have four jaws 240 with an included angle of 90 degrees between them, and there are four radial strip holes 211 and four involute holes 221.

[0050] In some embodiments, the involute slide rail plate 220 is disposed between the radial slide rail plate 210 and the base 100, and the limiting component 300 is disposed on the side of the radial slide rail plate 210 facing away from the base 100, so as to facilitate the mounting of the limiting component 300 on the clamping component 200. Specifically, since the radial slide rail plate 210 remains stationary relative to the base 100, the limiting component 300 can be disposed between the radial slide rail plate 210 to ensure that the relative position between the limiting component 300 and the clamping component 200 remains unchanged, thereby reducing errors and improving the accuracy of positioning the pipeline 500. The limiting component 300 can be a U-shaped plate with connecting plates on both sides. The connecting plates have screw holes, and the radial slide rail plate 210 has multiple screw holes in a direction perpendicular to the radial direction. The connecting plates can be fixed to the radial slide rail plate 210 using bolts. By replacing U-shaped plates of different widths, pipes of different diameters 500 can be adapted, improving the stability of the bend during beveling, reducing swaying, and thus improving the accuracy of the bevel and increasing the yield.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
