Implementation

[0032] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] See also Figure 1The present embodiment provides a large PE pipe cutting machine, including a base 10, an electric control box 20, a clamping assembly 30, an edge grinding assembly 50, a driving assembly 60 and a cutting assembly 70. The electric control box 20 is provided with two groups, and the two groups of the electric control boxes 20 are relatively distributed on one side of the base 10, and are used to drive the clamping assembly 30 to rotate. The clamping assembly 30 is provided with two groups, and the two groups of the clamping assemblies 30 are respectively installed on the opposite side of the two groups of the electric control boxes 20, and are used to clamp the two ends of the pipe to be cut. The driving assembly 60 is arranged on one side of the base 10, and the cutting assembly 70 is installed at the output end of the driving assembly 60 and is controlled by the driving assembly 60 to move toward the base 10. The edge grinding assembly 50 is arranged on the side of the cutting assembly 60. After the cutting assembly 60 cuts the pipe, the edge grinding assembly 50 is used to grind the cut surface of the pipe.

[0035] When cutting a large PE pipe, the large PE pipe can be placed on one side of the base 10, and the two ends of the large PE pipe can be clamped respectively by the clamping assembly 30, and the clamping assembly 30 is driven to rotate by the electric control box 20, thereby driving the large PE pipe to rotate, and the cutting assembly 70 is driven to move toward the base 10 by the driving assembly 60, and the large PE pipe clamped by the clamping assembly 30 is cut by the cutting assembly 70, so that the large PE pipe is broken into two parts, and then the cut surfaces of the two broken pipes are polished by the edge grinding assembly 50 to remove burrs generated during the cutting process, thereby improving the quality of the pipe cross section.

[0036] See also Figure 1 In one embodiment, a support plate 40 is installed on one side of the base 10, and a mounting plate 402 is fixedly installed on one side of the support plate 40. The driving assembly 60 includes a hydraulic cylinder 601, a piston rod 602 and a U-shaped bracket 603. The hydraulic cylinder 601 is fixedly installed on one side of the mounting plate 402, one end of the piston rod 602 is connected to the output end of the hydraulic cylinder 601, and the other end is connected to the U-shaped bracket 603. The cutting assembly 70 includes a cutting saw blade 701 and a cutting motor 703. The cutting motor 703 is fixedly installed on the side wall of the U-shaped bracket 603, the cutting saw blade 701 is arranged on the inner wall of the U-shaped bracket 603, and the output end of the cutting motor 703 is connected to the cutting saw blade 701 through a rotating shaft 702.

[0037] The cutting motor 703 drives the rotating shaft 702 to rotate, thereby driving the cutting saw blade 701 to rotate, and the hydraulic cylinder 601 drives the piston rod 602 to extend, thereby driving the U-shaped bracket 603 to move. When the U-shaped bracket 603 moves, it can drive the cutting motor 703, the rotating shaft 702 and the cutting saw blade 701 to move toward the base 10 as a whole, and the large PE pipe located on one side of the base 10 is cut by the rotating cutting saw blade 701.

[0038] See also Figure 1 In one embodiment, a second guide rail 401 is fixedly provided on one side of the support plate 40 , and a slider is fixedly provided on one side of the U-shaped bracket 603 , and the slider is slidably matched with the second guide rail 401 .

[0039] Through the sliding cooperation between the slider and the second guide rail 401, the U-shaped bracket 603 can maintain stable movement, thereby achieving stable cutting of large PE pipes.

[0040] See also Figure 2 and Figure 3 In one embodiment, the edge grinding assembly 50 includes an arc-shaped grinding sheet 505 , which is arranged on one side of the cutting saw blade 701 and is hingedly connected to the U-shaped bracket 603 , and one end of the arc-shaped grinding sheet 505 is in contact with the cutting saw blade 701 .

[0041] After the cutting saw blade 701 cuts the large PE pipe, the end of the arc-shaped grinding sheet 505 away from the cutting saw blade 701 can act on the outer wall of the large PE pipe. The large PE pipe provides thrust to the arc-shaped grinding sheet 505, thereby driving the arc-shaped grinding sheet 505 to move, so that the end of the arc-shaped grinding sheet 505 that is in contact with the cutting saw blade 701 rotates to the inner wall of the pipe. At this time, the inner wall of the arc-shaped grinding sheet 505 can be in contact with the inner edge and the outer edge of the pipe section at the same time. As the clamping assembly 30 drives the pipe to rotate, the pipe rotates compared to the arc-shaped grinding sheet 505. At this time, the arc-shaped grinding sheet 505 is used to grind the inner edge and the outer edge of the pipe section at the same time to remove burrs on the inner edge and the outer edge of the pipe.

[0042] See also Figure 2 and Figure 3 In one embodiment, a support rod 501 is fixedly provided on one side of the U-shaped bracket 603, and a pin rod 503 is fixedly provided on the end of the support rod 501 away from the U-shaped bracket 603. A sliding groove 504 for the pin rod 503 to extend into is opened on the side wall of the arc-shaped grinding sheet 505. The arc-shaped grinding sheet 505 is also connected to the U-shaped bracket 603 by an elastic member 502, and the elastic member 502 is used to provide elastic support for the arc-shaped grinding sheet 505.

[0043] When one end of the arc-shaped grinding sheet 505 away from the cutting saw blade 701 acts on the outer wall of the large PE pipe and the arc-shaped grinding sheet 505 moves, the pin rod 503 adaptively slides along the inside of the slide groove 504, and the elastic member 502 is compressed at this time; when the arc-shaped grinding sheet 505 has completed grinding and removing the burrs on the cross section of the pipe, the hydraulic cylinder 601 drives the piston rod 602 to retract, and then drives the U-shaped bracket 603 to move in the opposite direction, so as to drive the cutting motor 703, the rotating shaft 702 and the cutting saw blade 701 to move in the opposite direction as a whole, so that the cutting saw blade 701 is removed from between the two pieces of pipe, and the elastic support of the elastic member 502 can drive the arc-shaped grinding sheet 505 to move in the opposite direction until one end of the arc-shaped grinding sheet 505 is again attached to the side wall of the cutting saw blade 701, so as to realize the resetting of the arc-shaped grinding sheet 505, so as to facilitate the subsequent cutting and edge grinding of the large PE pipe.

[0044] See also Figure 3 In one embodiment, the side wall of the cutting saw blade 701 is provided with an annular groove 704 for one end of the arc-shaped grinding sheet 505 to extend into. Through this arrangement, one end of the arc-shaped grinding sheet 505 can smoothly follow the cutting saw blade 701 into the interior of the pipe, ensuring that when the end of the arc-shaped grinding sheet 505 away from the cutting saw blade 701 subsequently acts on the outer wall of the large PE pipe, the arc-shaped grinding sheet 505 can be turned into the inner side of the pipe, so that the inner wall of the arc-shaped grinding sheet 505 can be in contact with the inner edge and the outer edge of the pipe section at the same time.

[0045] In one embodiment, the elastic member 502 may be a spring or a metal spring, which is not limited here.

[0046] See also Figure 1 In one embodiment, the two groups of electric control boxes 20 are slidably arranged on one side of the base 10. After the large PE pipe is placed on one side of the base 10, the two groups of electric control boxes 20 slide relative to each other, thereby driving the two groups of clamping assemblies 30 to move relative to each other, and the two ends of the large PE pipe are clamped by the two groups of clamping assemblies 30. Then, the two groups of electric control boxes 20 drive the two groups of clamping assemblies 30 to rotate synchronously, thereby driving the large PE pipe to rotate, so that when the arc-shaped grinding sheet 505 is transferred to the inside of the pipe, the inner and outer edges of the pipe section can be synchronously polished.

[0047] See also Figure 1 In one embodiment, a first guide rail 101 is fixedly provided on one side of the base 10, and a slot compatible with the first guide rail 101 is opened on one side of the two groups of electric control boxes 20, and a limit plate 201 is fixedly provided on the side wall of the two groups of electric control boxes 20, and a locking bolt is provided on the limit plate 201.

[0048] One side of the two groups of electrical control boxes 20 is slidably matched with the first guide rail 101 through a slot to drive the two groups of clamping assemblies 30 to move toward each other to clamp the two ends of the large PE pipe. Then, by tightening the locking bolt, the limit plate 201 is limited to one side of the base 10 to limit the electrical control box 20 and ensure stable clamping of the large PE pipe.

[0049] In one embodiment, the clamping assembly 30 is a three-jaw chuck.

[0050] See also Figure 1 In one embodiment, a blade groove 102 is formed on one side of the base 10 for the cutting saw blade 701 to extend into.

[0051] In the embodiment of the present invention, when a large PE pipe is to be cut, the large PE pipe can be placed on one side of the base 10, and the two ends of the large PE pipe can be clamped by the clamping assembly 30 respectively, and the clamping assembly 30 is driven to rotate by the electric control box 20, thereby driving the large PE pipe to rotate, and the cutting assembly 70 is driven to move toward the base 10 by the driving assembly 60, and the large PE pipe clamped by the clamping assembly 30 is cut by the cutting assembly 70, so that the large PE pipe is cut into two parts, and then the cut surfaces of the two cut pipes are polished by the edge grinding assembly 50 to remove burrs generated during the cutting process, thereby improving the quality of the pipe cross section. Compared with the prior art, the automatic cutting of the large PE pipe can be realized, and the burrs on the cross section of the pipe after cutting can be automatically polished to improve the cutting quality of the pipe.

[0052] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
