Description

Technical Field

[0002] Plastic pipes are typically connected using thermofusion welding: first, the ends of two pipes are heated and then butt-welded to create a molten pool, fusing the two pipes into a single, continuous pipe. Because the molten pool has inner and outer flanges, the outer flange does not affect the product's function, but the inner wall of the pipe is for water flow. The inner flange will inevitably reduce the water pipe's diameter, thus decreasing the water flow rate. If this pipe is a sewage pipe, the inner flanged molten pool will also accumulate various types of debris, becoming a blockage point. Utility Model Content

[0014] This application has at least the following technical advantages over the prior art:

[0015] This application provides a cutting device for pipe manufacturing and processing. The cutting device includes: a fixed base, an end-face cutting component, a molten pool cutting assembly, a telescopic component, and a rotating component. The fixed base includes an upper end face and a lower end face arranged opposite each other. The end-face cutting component is disposed on the upper end face of the fixed base. The rotating component is disposed on the other end of the telescopic component away from the fixed base. The end-face cutting component contacts the end face of the pipe opening. The rotating component drives the fixed base to rotate, and the fixed base drives the end-face cutting component to rotate. During rotation, the end-face cutting component cuts the end face of the pipe opening, making the end face of the pipe opening perpendicular to the pipe's central axis.

The telescopic component is located on the lower end face of the fixed base, with one end penetrating the fixed base and connected to the molten pool cutting component. The telescopic component drives the molten pool cutting component to move along the central axis of the pipe, thereby enabling the molten pool cutting component to achieve longitudinal cutting of the molten pool on the inner surface of the pipe. This thoroughly removes the molten pool from the inner surface of the pipe, preventing the problem of easy blockage inside the pipe caused by the natural folding after the butt welding of two pipes.

Detailed Implementation

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0031] Plastic pipes are typically connected using hot-melt welding: first, the ends of two pipes are heated and then butt-welded to create a molten pool (b), fusing the two pipes into a single, continuous pipe. Because molten pool (b) consists of inner and outer flanges, the outer flange does not affect the product's function, but the inner wall of the pipe is for water flow. The inner flange will inevitably reduce the water pipe's diameter, thus decreasing the water flow rate. If this pipe is a sewage pipe, the inner flanged molten pool (b) will also accumulate various types of debris, becoming a blockage point.

[0032] To solve the above-mentioned technical problems, this application provides a cutting device for pipe production and processing, which cuts the molten pool b on the inner surface of the pipe to avoid the problem of easy blockage inside the pipe a due to the natural flanging after the butt welding of two pipes a, and grinds the end face of the open end of the pipe a so that the end face of the open end of the pipe a is perpendicular to the central axis of the pipe a, and removes the oxide layer generated by the oxidation of the pipe a due to exposure to air.

[0033] The following is in conjunction with the instruction manual. Figures 1-12 A detailed description is provided of the cutting device used in pipe production and processing.

[0034] This application provides a cutting device for pipe manufacturing and processing. The cutting device includes: a fixed base 1, including an upper end face and a lower end face arranged back to back; an end face cutting component 2, disposed on the upper end face of the fixed base 1, and in contact with the end face of the open end of the pipe a; a molten pool cutting assembly 3, disposed on the upper end face of the fixed base 1, and capable of extending into the interior of the pipe a; a telescopic component 4, disposed on the lower end face of the fixed base 1, with one end penetrating the fixed base 1 and connected to the molten pool cutting assembly 3; and a rotating component 5, disposed at the other end of the telescopic component 4 away from the fixed base 1.

[0035] Specifically, the cutting device for pipe manufacturing includes: a fixed base 1, an end face cutting component 2, a molten pool cutting assembly 3, a telescopic component 4, and a rotating component 5. The fixed base 1 includes an upper end face and a lower end face arranged opposite each other. The end face cutting component 2 is located on the upper end face of the fixed base 1. The rotating component 5 is located on the other end of the telescopic component 4 away from the fixed base 1. The end face cutting component 2 contacts the end face of the open end of pipe a. The rotating component 5 drives the fixed base 1 to rotate, and the fixed base 1 drives the end face cutting component 2 to rotate. During the rotation, the end face cutting component 2 cuts the end face of the open end of pipe a, making the end face of the open end of pipe a perpendicular to the central axis of pipe a. This facilitates welding operations between two pipes a and also removes oxygen from pipe a exposed to air. The oxide layer produced by the process is removed. The molten pool cutting component 3 is located on the upper end face of the fixed base 1 and can extend into the interior of the pipe a. The rotating component 5 drives the fixed base 1 to rotate, and the fixed base 1 drives the molten pool cutting component 3 to rotate. The molten pool cutting component 3 can perform circumferential cutting along the molten pool on the inner surface of the pipe a. The telescopic component 4 is located on the lower end face of the fixed base 1. One end of the telescopic component 4 passes through the fixed base 1 and is connected to the molten pool cutting component 3. The telescopic component 4 drives the molten pool cutting component 3 to move along the central axis of the pipe a. The molten pool cutting component 3 can thus achieve longitudinal cutting of the molten pool b on the inner surface of the pipe a, thereby completely removing the molten pool b on the inner surface of the pipe a and avoiding the problem of easy blockage inside the pipe a due to the natural flange generated after the two pipes a are butt welded.

[0036] In some optional embodiments, the end face cutting component 2 includes a plurality of first cutting elements 21, which are disposed on the upper end face and uniformly arranged along the circumference of the fixed base 1.

[0037] Specifically, each of the first cutting elements 21 is a cutting head. The cutting head cuts the end face of the pipe opening, making the end face of the pipe a flat and perpendicular to the central axis of the pipe a. While the cutting head is cutting the end face of the pipe a, it can also remove the oxide layer formed by the pipe a being exposed to air for a long time. Multiple first cutting elements 21 are arranged on the upper end face and evenly distributed along the circumference of the fixed base 1, which makes the cutting efficiency higher. If one or more of the first cutting elements 21 are damaged during the operation of the end face cutting component 2, it will not affect the cutting operation.

[0038] In use, firstly, the end-face cutting component 2 is inserted into the welded integral pipe a. Then, the end face of one open end of the integral pipe a is pressed against the upper surface of the fixed base 1. Next, a level is used to align the integral pipe a and the cutting device used for pipe production and processing on the same horizontal axis, and they are fixed in place with relevant clamps. Then, the rotating component 5 is activated, causing it to drive the cutting device to rotate 360 ​​degrees at high speed. Because one end face of the integral pipe a is pressed against the fixed base 1, and the upper surface of the fixed base 1 is equipped with the first cutting element 21, the first cutting element 21 will cut the end face of the open end of the integral pipe a, making the end face of the open end of the integral pipe a flat and perpendicular to the central axis of the pipe a. While cutting the end face of the open end of the integral pipe a, the first cutting element 21 can also remove the oxide layer formed by the long-term exposure of the pipe a to air.

[0039] In some optional embodiments, the fixing base 1 is provided with a plurality of receiving grooves 11 recessed from the upper end face to the lower end face. The plurality of receiving grooves 11 are evenly arranged along the circumference of the fixing base 1, and the first cutting element 21 is provided in a one-to-one correspondence with the receiving grooves 11.

[0040] Specifically, each receiving groove 11 is provided with a first screw hole 111 penetrating the fixing base 1, and a fourth locking component 211 penetrates the first cutting element 21 and the first screw hole 111, thereby installing the first cutting element 21 into the receiving groove 11. Optionally, the fourth locking component 211 is a screw. Multiple receiving grooves 11 are evenly arranged along the circumference of the fixing base 1, and the first cutting element 21 and the receiving groove 11 are arranged in a one-to-one correspondence. Multiple first cutting elements 21 are arranged on the upper end face and evenly arranged along the circumference of the fixing base 1, which makes the cutting efficiency higher. When one or more of the first cutting elements 21 are damaged during the operation of the end face cutting component 2, the cutting operation is not affected.

[0041] In some optional embodiments, the molten pool cutting assembly 3 includes a first fixing element 31, a second cutting element 32, a tool head support 33, a fixing assembly 34, and a first locking component 35. The tool head support 33 is located between the second cutting element 32 and the fixing assembly 34, and is disposed on the fixing assembly 34. One end of the second cutting element 32 passes through the first fixing element 31 and is slidably connected to the tool head support 33. The fixing assembly 34 is connected to the telescopic component 4, and the first locking component 35 connects the first fixing element 31, the fixing assembly 34, and the fixing base 1.

[0042] Specifically, the second cutting element 32 is a cutting tool head, and multiple second cutting elements 32 are provided. The first fixing element 31 is provided with multiple square holes 312. Optionally, each square hole 312 is an inclined hole. One end of the second cutting element 32 passes through the square hole 312 and is slidably connected to the tool head support 33. The end face of the tool head support 33 facing the second cutting element 32 is provided with a slide rail 331. The second cutting element 32 is slidably connected to the slide rail 331. The fixing component 34 is used to fix the second cutting element 32, thereby connecting the first fixing element 31, the second cutting element 32, the tool head support 33, and the fixing component 34 into a whole. The first locking component 35 includes multiple first locking elements, each of which is a screw. The multiple screws are arranged along the circumference of the first fixing element 31. Each screw passes through the first fixing element 31, the fixing component 34, and the fixing base 1, thereby setting the second cutting element 32, the first fixing element 31, and the fixing component 34 on the fixing base 1. The telescopic component 4 is mounted on the fixed base 1. The telescopic component 4 is a cylinder. The stroke rod 41 of the cylinder passes through the first central hole 14 of the fixed base 1 and is connected to the fixed component 34.

[0043] In use, the telescopic component 4 is activated, causing the telescopic component 4 to extend its stroke rod 41 forward under increased internal hydraulic pressure. This pushes the fixed component 34 towards the direction of the second cutting element 32. The fixed component 34, the cutter head support 33, the first fixed element 31, and the second cutting element 32 will all move together towards the direction of the second cutting element 32. The second cutting element 32 is slidably connected to the cutter head support 33. The square hole 312 of the first fixed element 31 is an inclined hole, so the second cutting element 32 will move forward at an angle, that is, the second cutting element 32 is expanding outward. When the second cutting element 32 is close to the molten pool b of the integral pipe a, the rotating component 5 is activated again, causing it to drive the molten pool cutting component 3 to rotate 360 ​​degrees at high speed. At this time, the second cutting element 32 is expanding outward while also rotating at a high speed. In this way, when the second cutting element 32 reaches the molten pool b of the integral pipe a, it will slowly cut off the inner edge of the molten pool b. Once the interior of the entire pipe a becomes smooth and flat again, the internal pressure of the telescopic component 4 is no longer increased, but is slowly released, causing the travel rod 41 of the telescopic component 4 to retract. This causes the fixed component 34 to move towards the rotating component 5. Since the fixed component 34, the cutter head support 33, the first fixed element 31, and the second cutting element 32 are connected as a whole, these components will all move together towards the rotating component 5, thereby causing the second cutting element 32 to retract and simultaneously closing the rotating component 5. When the weld pool b of the entire pipe a and the pipe cutting device return to their original static state, the pipe cutting device is moved from the interior of the entire pipe a to the outside, thus completing the entire process.

[0044] In some optional embodiments, multiple second cutting elements 32 are provided, and multiple slides 331 are provided on the cutter head support 33. The multiple slides 331 extend radially from the center of the cutter head support 33 to the surrounding area, and the second cutting elements 32 are provided in a one-to-one correspondence with the slides 331.

[0045] Specifically, the number of slides 331 is the same as the number of second cutting elements 32. Each second cutting element 32 corresponds to one slide 331, and each second cutting element 32 is slidably connected along the slide 331. Each second cutting element 32 includes a cutting end 321, a support body 322, and a sliding end 323. The cutting end 321 and the sliding end 323 are respectively located at both ends of the support body 322, and the sliding end 323 is connected to the slide 331. The sliding end 323 is T-shaped, and the slide 331 formed by the tool head support 33 is also T-shaped. The sliding end 323 of each second cutting element 32 is slidably connected to the slide 331 of the tool head support 33.

[0046] In some optional embodiments, the fixing component 34 includes a second fixing plate 341, a third fixing plate 342, a second locking component 343, and a third locking component 344. The second fixing plate 341 and the third fixing plate 342 are stacked. The second fixing plate 341 is provided with a limiting hole 3411. The cutter head support 33 is disposed in the limiting hole 3411. The second locking component 343 passes through the limiting hole 3411 and is connected to the cutter head support 33. The third locking component 344 connects the second fixing plate 341 and the third fixing plate 342. The third fixing plate 342 is connected to the telescopic component 4.

[0047] Specifically, the cutter head support 33 is provided with a second screw hole 332, and the second fixing plate 341 is provided with multiple sixth screw holes 3423. The second screw holes 332 and the sixth screw holes 3423 are arranged one-to-one. The second locking component 343 is a screw, and multiple second locking components 343 are provided. Each second locking component 343 passes through the sixth screw hole 3423 and the limiting hole 3411 and connects to the second screw hole 332. The third locking component 344 is a screw, and multiple third locking components 344 are provided. The second fixing plate 341 is provided with multiple third screw holes 3413, and the third fixing plate 342 is provided with multiple fourth screw holes 3422. The third screw holes 3413 and the fourth screw holes 3422 are arranged one-to-one. The screws pass through the third screw holes 3413 and the fourth screw holes 3422, thereby connecting the second fixing plate 341 and the third fixing plate 342 together.

[0048] Furthermore, the first fixing element 31 is provided with multiple first screw holes 311, the second fixing plate 341 is provided with multiple second screw holes 3412, the third fixing plate 342 is provided with multiple third screw holes 3421, and the fixing base 1 is provided with multiple fourth screw holes 12. The first screw holes 311, second screw holes 3412, third screw holes 3421, and fourth screw holes 12 are provided in a one-to-one correspondence. The first locking component 35 includes multiple first locking elements, each of which is a screw. The multiple screws are arranged circumferentially along the first fixing element 31, and each screw passes through the fourth screw hole 12, the third screw hole 3421, the second screw hole 3412, and the first screw hole 311, thereby setting the second cutting element 32, the first fixing element 31, and the fixing assembly 34 on the fixing base 1. The telescopic component 4 is provided on the fixing base 1. The telescopic component 4 is a cylinder. The stroke rod 41 of the cylinder passes through the first central hole 14 of the fixing base 1 and connects to the second central hole 3424 of the third fixing plate 342. The rotating component 5 is connected to the telescopic component 4. The rotating component 5 can drive the telescopic component 4, the fixed base 1, the end face cutting component 2, and the molten pool cutting component 3 to rotate together.

[0049] In some alternative embodiments, the shape of the limiting hole 341 formed by the second fixing plate 341 is the same as the cross-sectional shape of the cutter head support 33.

[0050] Specifically, the shape of the limiting hole 341 formed by the second fixing plate 341 is the same as the cross-sectional shape of the cutter head support 33, so that the cutter head support 33 can be just locked in the limiting hole 3411 so that the cutter head support 33 can be installed on the second fixing plate 341.

[0051] In some alternative embodiments, a clamping member 6 is also included, which connects the telescopic member 4 and the rotating member 5.

[0052] Specifically, the fixed base 1 is provided with a fifth screw hole 13, and there are multiple fifth screw holes 13. The upper end of the telescopic component 4 is provided with a fixing post 42. The fifth screw holes 13 and the fixing posts 42 are provided one-to-one. The fixing posts 42 pass through the fifth screw holes 13, thereby installing the telescopic component 4 onto the fixed base 1. The lower end of the telescopic component 4 is fixed by the clamping component 6. The rotating component 5 is connected to the clamping component 6, so that the rotating component 5 can drive the telescopic component 4, the fixed base 1, the end face cutting component 2, and the molten pool cutting assembly 3 to rotate together.

[0053] In some optional embodiments, the clamping component 6 includes a first clamping plate 61, a second clamping plate 62 and a third clamping plate 63, the second clamping plate 62 and the third clamping plate 63 being located at both ends on the same side of the first clamping plate 61, and the second clamping plate 62 and the third clamping plate 63 being connected to the first clamping plate 61 by bolt assemblies.
