Description

Technical Field

[0001] The invention belongs to the technical field of pipeline processing, and in particular relates to an ultra-fine high-pressure pipeline non-destructive cutting device. Background Art

[0002] Tube cutters are commonly used pipe cutting devices in industrial production. Due to the different materials of pipes (copper pipes, iron pipes, PVC hoses, etc.), there are various types of cutting tools. At present, the existing pipe cutters for cutting metal pipes are mainly suitable for hard thin-walled metal pipes or large-diameter metal pipes, and are not suitable for cutting extremely thin pipes.

[0003] In the field of pressure control, pressure control pipeline cutting and production are often involved, especially in high-pressure pressure control. In order to ensure its pressure resistance and high-pressure control accuracy, extremely fine and thick-walled stainless steel pressure pipelines (inner diameter 0.762mm) are often used. The production of such ultra-fine high-pressure pipelines is extremely difficult. Because of its very fine diameter, the existing pipe cutters or cutting tools are prone to tilting when cutting pipelines, and the cuts are uneven. This lossy cutting will cause deformation of the cut end face and blockage of the end face pores, making the pipeline unable to be used normally. In addition, the existing pipeline cutting device can usually only perform simple cutting on the pipeline, and often cannot meet the requirements of some special end face angles, which greatly affects the applicability of the pipeline cutting device.

[0004] It can be seen from the above that the existing technology has the problem of poor applicability of pipeline cutting devices, and a super-fine high-pressure pipeline non-destructive cutting device is needed. Summary of the invention

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] One embodiment of the present invention provides an ultra-fine high-pressure pipeline non-destructive cutting device. Figures 1 to 4 As shown, the ultra-fine high-pressure pipeline non-destructive cutting device of the embodiment of the present invention includes a base 1, a driving member 2, a cutting member 3, a cover plate 4, an angle adjustment member 6 and a first guide rail 8. The base 1 is provided with a mounting groove; the driving member 2 is drivingly connected to the cutting member 3 and both are arranged in the mounting groove; the cover plate 4 is covered on the notch of the mounting groove, and the cover plate 4 has an avoidance opening 5 so that at least a part of the cutting member 3 is exposed from the cover plate 4, and the pipeline to be cut is placed on the cover plate 4; the angle adjustment member 6 is rotatably arranged on the cover plate 4, the angle adjustment member 6 is connected to at least a part of the pipeline to be cut and drives the pipeline to be cut to rotate, so as to adjust the cutting end face angle of the pipeline to be cut, and the first guide rail 8 is arranged on the cover plate 4, the angle adjustment member 6 is slidably connected to the first guide rail 8, and can slide along the first guide rail 8 and drive the pipeline to be cut to move, so as to adjust the cutting end face position of the pipeline to be cut.

[0030] Through the above structural setting, the ultra-fine high-pressure pipeline non-destructive cutting device of the embodiment of the present invention can adjust the angle adjustment member 6 to the required position and angle according to the use requirements, and then drive the pipeline to be cut to rotate to the preset position, so as to obtain the required cutting end face angle, which greatly improves the applicability of the pipeline cutting device.

[0031] In one embodiment, the driving member 2 is a motor, the cutting member 3 is a cutting blade, and the cutting member 3 is sleeved on the output shaft of the motor, so that it rotates and cuts under the drive of the motor. It can be understood that the cutting member 3 is arranged vertically.

[0032] like Figure 3 As shown, the ultra-fine high-pressure pipeline non-destructive cutting device also includes a mounting bracket 14, which is arranged in the mounting groove, and the driving member 2 is fixedly connected to the mounting bracket 14, so that the driving member 2 and the cutting member 3 are fixed in the mounting groove.

[0033] like Figure 3 and Figure 4As shown, the base 1 is surrounded by a bottom plate 16, two left and right side plates 17, a front plate 18 and a rear plate 19 to form a base body with an opening, and a cover plate 4 is arranged on the base 1 to block the opening, that is, the notch of the installation groove, and the cover plate 4 is connected and fixed to the base 1 through a second connecting member 13. The size of the cover plate 4 is larger than the top size of the base 1, so that a part of the cover plate 4 extends horizontally from the base 1, thereby having sufficient operating space.

[0034] In one embodiment, in order to achieve precise cutting of the pipeline to be cut, the thickness of the cutting blade is less than 0.2 mm, and the speed of the motor is greater than 20,000 rpm. This makes the ultra-fine high-pressure pipeline non-destructive cutting device have a strong cutting ability and will not cause deformation of the cutting end surface or blockage of the end surface pores.

[0035] like Figure 1 to Figure 2 As shown, the ultra-fine high-pressure pipeline non-destructive cutting device also includes a first connecting member 7, which is passed through the angle adjustment member 6 and one end of which extends into the first guide rail 8, so that the angle adjustment member 6 can rotate relative to the first connecting member 7 and be slidably connected to the first guide rail 8 through the first connecting member 7.

[0036] In one embodiment, the first guide rail 8 is parallel to the cutting member 3. Specifically, the first guide rail 8 extends along the width direction of the cover plate 4. Similarly, the avoidance opening 5 is in the shape of a strip extending along the width direction of the cover plate 4.

[0037] Specifically, the first guide rail 8 is a T-shaped guide rail, and one end of the first connecting member 7 has a matching T-shaped block, which is accommodated in the T-shaped guide rail and slides along the T-shaped guide rail. In a specific embodiment, the first connecting member 7 includes a screw and a T-shaped nut, and the angle adjustment member 6 has a central through hole, one end of the screw passes through the central through hole and is threadedly connected to the T-shaped nut, and the T-shaped nut is accommodated in the T-shaped guide rail and slides along the T-shaped guide rail, so that the angle adjustment member 6 can rotate relative to the screw and can follow the first connecting member 7 to slide along the first guide rail 8.

[0038] In one embodiment, the angle adjustment member 6 includes a rotating block and a baffle disposed on the rotating block, and the baffle abuts against the pipeline to be cut. Specifically, the rotating block is a circular block with a portion cut off to form a straight edge, and the baffle is located at the straight edge, and the center of the circle has the above-mentioned central through hole. It can be understood that the angle between the baffle and the cutting member 3 is the cutting end face angle of the pipeline to be cut.

[0039] Furthermore, the angle adjustment member 6 also includes a clamping member, which is used to clamp and fasten the pipeline to be cut and the blocking bar. By providing the clamping member, the pipeline to be cut can be fixed on the angle adjustment member 6, thereby ensuring that the pipeline to be cut will not shake during the cutting process, avoiding uneven incisions, affecting the cutting effect, and blocking the pipeline.

[0040] In one embodiment, the ultra-fine high-pressure pipeline non-destructive cutting device also includes a lifting mechanism, which is arranged in the installation groove, and the lifting mechanism is connected to the driving member 2 and the cutting member 3, and is used to drive the driving member 2 and the cutting member 3 to move up and down. Specifically, the lifting mechanism includes a lifting platform and a lifting motor, and the mounting bracket 14 is located on the lifting platform. The lifting motor is connected to the lifting platform to drive the lifting platform to move up and down. Through the above arrangement, the height of the cutting member 3 exposed from the cover plate 4 can be adjusted according to the diameter of the pipeline to be cut, so as to meet the cutting requirements of different types of pipelines.

[0041] like Figure 1 , Figure 2 , Figure 4 As shown, the ultra-fine high-pressure pipeline non-destructive cutting device also includes a bending member 9 and a limiting column 12. There are two limiting columns 12, and the two limiting columns 12 are arranged at intervals. The pipeline to be cut is located between the two limiting columns 12. The bending member 9 is movably arranged on the cover plate 4, and the bending member 9 drives the pipeline to be cut to rotate so that the pipeline to be cut is bent along the limiting column 12.

[0042] like Figure 1 to Figure 2 As shown, a second guide rail 11 is provided on the cover plate 4, and the second guide rail 11 is arc-shaped, and the bending member 9 is located in the second guide rail 11. The ultra-fine high-pressure pipeline non-destructive cutting device also includes a rotating handle 10, which is located at the bottom of the cover plate 4, and one end of the rotating handle 10 is rotatably connected to the cover plate 4, and the other end extends horizontally from the cover plate 4. The bending member 9 is connected to the rotating handle 10, so that the rotating handle 10 drives the bending member 9 to move along the second guide rail 11. When it is necessary to bend the pipeline to be cut, the operator holds the rotating handle 10 by hand and rotates the rotating handle 10, so that the bending member 9 drives the pipeline to be cut to rotate relative to the limit column 12 to achieve bending. Furthermore, the bending member 9 is a bending roller.

[0043] In one embodiment, the ultra-fine high-pressure pipeline non-destructive cutting device further includes a length mark 15, which is disposed on the cover plate 4 and is used to measure the length of the pipeline to be cut. Specifically, the length mark 15 extends along the length direction of the cover plate 4.

[0044] In one embodiment, the bending member 9 and the angle adjustment member 6 are respectively located at the two ends of the cover plate 4 along the length direction. Correspondingly, the first guide rail 8 and the second guide rail 11 are also respectively located at the two ends of the cover plate 4 along the length direction, so as not to interfere with each other and complete the angle adjustment and bending process independently.

[0045] The ultra-fine high-pressure pipeline non-destructive cutting device of the above-mentioned embodiment of the present invention achieves the following technical effects: the angle adjustment member can be adjusted to the required position and angle according to usage requirements, thereby driving the pipeline to be cut to rotate to a preset position, thereby obtaining the required cutting end face angle, greatly improving the applicability of the pipeline cutting device.

[0046] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
