Detailed Implementation
[0028] 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.
[0029] 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.
[0030] The connection method for plastic pipe A is hot-melt welding. However, if the welding end face of pipe A is not flat or the oxide layer is not removed, it is very easy to cause a false weld when butt welding pipe A, which may cause the pipe to burst during use, resulting in flooding of houses or road collapse, causing significant losses.
[0031] To solve the above-mentioned technical problems, this application provides a pipe end face cutting device that can cut the end of pipe a to be welded, remove the oxide layer at the end of pipe a, and make the welding surface of the end of pipe a flat.
[0032] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1-11 A detailed description of the pipe end face cutting device is provided.
[0033] This application provides a pipe end face cutting device, which includes: a fixed base 1, including an upper end face and a lower end face disposed opposite to each other; 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 to be cut; a telescopic component 3, disposed on the lower end face of the fixed base 1, with one end passing through the fixed base 1 and connected to the end face cutting component 2; a rotating component 4, disposed on the other end of the telescopic component 3 away from the fixed base 1; and a locking component 5, with one end connected to the pipe a to be cut and the other end connected to the fixed base 1.
[0034] Specifically, the pipe end face cutting device includes: a fixed base 1, an end face cutting component 2, a telescopic component 3, a rotating component 4, and a locking component 5. The locking component 5 connects the pipe to be cut (a) and the fixed base 1, thereby fixing the pipe end face cutting device to the pipe to be cut (a). The fixed base 1 includes an upper end face and a lower end face that are arranged opposite to each other. The end face cutting component 2 is disposed on the upper end face of the fixed base 1. The telescopic component 3 drives the fixed base 1 to extend and retract, thereby driving the end face cutting component 2 to move. The rotating component 4 is disposed at the other end of the telescopic component 3 away from the fixed base 1. The end face cutting component 2 contacts the end face of the open end of the pipe (a). The rotating component 4 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 the pipe (a), making the end face of the open end of the pipe (a) perpendicular to the central axis of the pipe (a), which facilitates welding operations between two pipes (a) and can also remove the oxide layer generated by the pipe (a) due to oxidation caused by exposure to air.
[0035] In some optional embodiments, the end face cutting component 2 includes a cutting plate 21, a cutting element 22 and a push plate 23. The cutting plate 21 and the push plate 23 are stacked and fixedly connected. The cutting element 22 is disposed on the upper end face of the cutting plate 21 facing away from the push plate 23.
[0036] Specifically, the cutting plate 21 includes an upper end face and a lower end face, and the push plate 23 includes an upper end face and a lower end face. The lower end face of the cutting plate 21 is in contact with the upper end face of the push plate 23. The cutting plate 21 is provided with multiple third screw holes 212, and the push plate 23 is provided with multiple fourth screw holes 231. The third screw holes 212 and the fourth screw holes 231 are arranged in a one-to-one correspondence. A fixing bolt 24 passes through one third screw hole 212 and one fourth screw hole 231 to fix the cutting plate 21 and the push plate 23 together. The cutting element 22 is provided on the upper end face of the cutting plate 21. The cutting element 22 is a cutting head. The cutting head cuts the end face of the open end of the pipe a, making the end face of the open end of the pipe a flat and perpendicular to the central axis of the pipe a. While the cutting head cuts the end face of the open end of the pipe a, it can also remove the oxide layer generated by the long-term exposure of the pipe a to air oxidation.
[0037] Furthermore, the cutting plate 21 can be any shape, such as circular, elliptical, or regular polygonal. The shape of the push plate 23 is the same as that of the cutting plate 21.
[0038] In some alternative embodiments, multiple cutting elements 22 are provided, and the multiple cutting elements 22 are uniformly arranged along the circumference of the cutting plate 21.
[0039] Specifically, multiple cutting elements 22 process the end face of the open end of the pipe a, which usually has a higher cutting speed than a single cutting element 22. Multiple cutting elements 22 can remove the oxide layer at the end of the pipe a more quickly and grind the end of the pipe a flat more quickly so that the end of the pipe a can be welded to other pipes a, thereby improving productivity and reducing processing time.
[0040] In some optional embodiments, the cutting plate 21 is provided with a plurality of receiving grooves 211 recessed from its upper end to its lower end. The plurality of receiving grooves 211 are evenly arranged along the circumference of the cutting plate 21, and the cutting element 22 and the receiving grooves 211 are arranged in a one-to-one correspondence.
[0041] Specifically, the cutting element 22 is disposed inside the receiving groove 211. Each receiving groove 211 is provided with a first screw hole 25 penetrating the cutting plate 21, and the cutting element 22 is provided with a second screw hole 221. A locking element 26 penetrates the cutting element 22, the second screw hole 221, and the first screw hole 25, thereby installing the cutting element 22 in the receiving groove 211. Optionally, the locking element 26 is a screw. Multiple receiving grooves 211 are evenly arranged along the circumference of the cutting plate 21, and the cutting elements 22 and receiving grooves 211 are arranged in a one-to-one correspondence. Multiple cutting elements 22 are disposed on the upper end face of the cutting plate 21 and evenly arranged along the circumference of the cutting plate 21, which makes the cutting efficiency higher. When one or more cutting elements 22 are damaged during the operation of the end face cutting component 2, the cutting operation is not affected.

The first clamping plate 61, the second clamping plate 62, and the third clamping plate 63 work together to fix the telescopic component 3.

[0045] Specifically, the lower base of the cylinder is positioned between the third clamping plate 63 and the first clamping plate 61, and between the second clamping plate 62 and the first clamping plate 61. The distance between the second clamping plate 62 and the first clamping plate 61 is adjusted by adjusting the first adjusting bolt 64, thereby adjusting the tightness of the clamping of the lower end of the telescopic component 3 by the second clamping plate 62 and the first clamping plate 61. The distance between the third clamping plate 63 and the first clamping plate 61 is adjusted by adjusting the second adjusting bolt 65, thereby adjusting the tightness of the clamping of the lower end of the telescopic component 3 by the third clamping plate 63 and the first clamping plate 61.

The third fixing element 33 is fastened with bolts.
[0047] In some alternative embodiments, the rotating component 4 is a motor, and the output shaft of the motor is connected to the first clamping plate 61.
