Description

Technical Field

[0001] This utility model relates to the field of spiral tube processing technology, specifically to a spiral tube chamfering device that is easy to clean. Background Technology

[0002] Spiral welded pipes are increasingly popular in industries such as oil and gas, slurry transportation, and urban construction due to their advantages such as high pressure resistance, low resistance, low temperature resistance, corrosion resistance, and convenient installation and maintenance. In the production process of spiral welded pipes, both ends of the steel pipe need to be chamfered, and the existing chamfering process usually uses a chamfering machine.

[0003] In the spiral tube chamfering device disclosed in CN214053791U, a protective cover is installed on the side wall of its frame to prevent waste from splashing and injuring the operator, while also gathering the waste for easy collection.

[0004] When chamfering the spiral tube, the cut waste material is in strips and tends to accumulate after winding together. However, the above-mentioned document first guides the waste material with a protective cover. This step easily causes the strip-shaped waste material to accumulate inside the protective cover and is not easy to be discharged into the waste bin. In addition, the waste material is temporarily collected in the waste bin. The accumulated waste material occupies a lot of space, causing the waste bin to fill up easily. This requires pulling out and emptying the waste bin multiple times, which is more cumbersome and also affects the processing efficiency of the spiral tube. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] In this technical solution, a spiral tube chamfering device that is easy to clean includes a base 1 and a mounting plate 2. The mounting plate 2 is installed on the upper wall of the base 1, and a chamfering mechanism 3 is installed on the side wall of the mounting plate 2. The chamfering mechanism 3 can fit against the side wall of the external spiral tube.

[0024] A collection mechanism 4 is installed on the upper wall of the base 1. The collection mechanism 4 is located below the chamfering mechanism 3. The collection mechanism 4 includes a collection cylinder 41, a discharge port 42, a rotating shaft 43, a roller 44, and a protruding plate 45. The collection cylinder 41 is installed on the upper wall of the base 1. The discharge port 42 is opened on the side wall of the collection cylinder 41. The rotating shaft 43 is inserted into the side wall of the collection cylinder 41. The roller 44 is installed on the outer side wall of the rotating shaft 43. The roller 44 is located inside the collection cylinder 41. The protruding plate 45 is installed on the outer side wall of the roller 44.

[0025] In this technical solution, when using this device to chamfer the spiral tube, the spiral tube is first placed on an external conveying device, which drives the spiral tube to rotate and move forward. Then, this device is fixed in front of the spiral tube to support it, and the position of the chamfering mechanism 3 is adjusted so that its cutting tool 34 fits against the outer wall of the spiral tube to chamfer the spiral tube.

[0026] During the chamfering process, the strip-shaped waste material cut off will fall directly into the collection cylinder 41. The waste material entering the collection cylinder 41 will be driven by the roller 44 and discharged directly from the discharge port 42, and then fall into the collection trough 7 on the outside of the collection cylinder 41. This avoids the accumulation of waste material in the collection cylinder 41, which would affect the chamfering of the spiral tube by this device. At the same time, it does not require the collection cylinder 41 to be tilted multiple times, which can speed up the chamfering efficiency of the spiral tube.

[0027] The protruding plate 45 can be used to move the waste material into the collection trough 7.

[0028] In addition, the rotating shaft 43 in this paper is connected to an external motor so that the motor can drive the rotating shaft 43 to rotate.

[0029] In some technical solutions, a material collection trough 5 is installed on the side wall of the collection cylinder 41. The inner cavity of the material collection trough 5 is connected to the inner cavity of the collection cylinder 41 through the discharge port 42. An electrically controlled push rod 6 is installed on the side wall of the material collection trough 5. The electrically controlled push rod 6 is electrically connected to an external power source. A pressure plate 7 is installed at the output end of the electrically controlled push rod 6. The pressure plate 7 can slide up and down in the material collection trough 5.

[0030] In this technical solution, an installation hole is provided on the outer side of the collection cylinder 41, and a pin is installed on the side wall of the collection trough 5. By inserting the pin into the installation hole, the collection trough 5 is installed on the side wall of the collection cylinder 41.

[0031] After the waste material is discharged into the collection trough 5, the staff can control the electric push rod 6 to push it downward, which will cause the pressure plate 7 to slide downward, compressing the waste material and making it concentrated into blocks, which will facilitate its collection and stacking later.

[0032] In some technical solutions, the mounting plate 2 includes a plate body 21, a connecting hole 22, a connecting rod 23, a screw 24, and a threaded hole 25. The connecting rod 23 is installed on the upper wall of the base 1, and the connecting hole 22 is opened on the lower wall of the plate body 21. The connecting rod 23 can be inserted into the connecting hole 22. The threaded hole 25 is opened on the side wall of the plate body 21. The threaded hole 25 is connected to the connecting hole 22. The screw 24 is screwed into the threaded hole 25 and can fit against the side wall of the connecting rod 23.

[0033] In this technical solution, the height of the mounting plate 2 can be adjusted to adjust the position of the chamfering mechanism 3, so that the upper pressure roller 31 in the chamfering mechanism 3 is as shown in the attached figure. Figure 2 As shown, it can be pressed above the inner wall of the lower end of the spiral tube. After adjusting the height of the mounting plate 2, the height of the mounting plate 2 can be locked by tightening the screw 24.

[0034] In some technical solutions, the chamfering mechanism 3 includes an upper pressure roller 31, a sliding groove 32, a slider 33, a cutting tool 34, and an adjusting bolt 35. The upper pressure roller 31 is installed on the side wall of the mounting plate 2. The side wall of the mounting plate 2 is provided with a sliding groove 32. The slider 33 is slidably installed in the sliding groove 32. The cutting tool 34 is installed on the side wall of the slider 33. The cutting tool 34 can fit against the side wall of the external spiral tube. The adjusting bolt 35 is screwed into the lower wall of the mounting plate 2. The adjusting bolt 35 can be inserted into the sliding groove 32 and rotatably installed on the lower wall of the slider 33.

[0035] In this technical solution, after the upper pressure roller 31 is in contact with the inner wall of the lower end of the spiral tube, the position of the cutting tool 34 can be adjusted by sliding the slider 33 according to the thickness of the spiral tube, so that the cutting tool 34 can be in contact with the outer wall of the spiral tube. Then the external conveying equipment drives the spiral tube to rotate, and at this time the cutting tool 34 will perform chamfering on the spiral tube.

[0036] During the chamfering process, the adjusting bolt 35 needs to be rotated slowly and at a constant speed to allow the cutting tool 34 to rise slowly until the chamfer of the spiral tube meets the standard.

[0037] In some technical solutions, the side wall of the plate 21 is provided with a spherical groove 8, and a ball bearing 9 is installed in the spherical groove 8. The ball bearing 9 can fit against the side wall of the external spiral tube.

[0038] In this technical solution, since the spiral tube is in a rotating state during the processing, the device is equipped with a ball bearing 8 and a ball bearing 9 on the side wall of its plate 21. The ball bearing 9 reduces the friction generated when the spiral tube contacts the plate 21, thus avoiding affecting the rotation of the spiral tube.

[0039] In some technical solutions, the upper wall of the base 1 is equipped with a reinforcing rib 10, and the side wall of the reinforcing rib 10 can fit against the side wall of the plate 21.

[0040] In this technical solution, the reinforcing rib 10 can support the mounting plate 2, improve the strength of the mounting plate 2, and prevent the mounting plate 2 from bending or other issues that would affect the processing effect of the spiral tube chamfer.

[0041] Working principle: First, adjust the height of the mounting plate 2 so that it can block the spiral tube and the upper pressure roller 31 in the chamfering mechanism 3 can press against the inner wall of the lower end of the spiral tube. After adjusting the height of the mounting plate 2, the height of the mounting plate 2 can be locked by tightening the screw 24.

[0042] Then the conveying equipment drives the spiral tube to rotate and move forward. Then the device is fixed in front of the spiral tube to support the spiral tube. Then, according to the thickness of the spiral tube, the sliding block 33 can be slid to adjust the position of the cutting tool 34 so that the cutting tool 34 can fit against the outer wall of the spiral tube. Then the external conveying equipment drives the spiral tube to rotate, and at this time the cutting tool 34 will chamfer the spiral tube.

[0043] During the chamfering process, the adjusting bolt 35 needs to be rotated slowly and at a constant speed to allow the cutting tool 34 to rise slowly until the chamfer of the spiral tube meets the standard.

[0044] During the chamfering process, the strip-shaped waste material cut off will fall directly into the collection cylinder 41. The waste material entering the collection cylinder 41 will be driven by the roller 44 and discharged directly from the discharge port 42, and then fall into the collection trough 7 on the outside of the collection cylinder 41. This avoids the accumulation of waste material in the collection cylinder 41, which would affect the chamfering of the spiral tube by this device. At the same time, it does not require the collection cylinder 41 to be tilted multiple times, which can speed up the chamfering efficiency of the spiral tube.

[0045] After the waste material is discharged into the collection trough 5, the staff can control the electric push rod 6 to push it downward, which will cause the pressure plate 7 to slide downward, compressing the waste material and making it concentrated into blocks, which will facilitate its collection and stacking later.
