Description

Technical Field

[0001] This utility model relates to the technical field of gas pipe processing equipment, specifically to a rapid cutting device for the oxide layer of PE pipe electrofusion welding joint. Background Technology

[0002] PE pipes are widely used in urban gas pipeline systems, meeting the gas needs of various sectors. Before welding, PE pipe ends typically require cutting and grinding. This grinding removes burrs from the weld seam, improving the pipe's sealing and preventing leaks, bursts, and other safety accidents. Grinding also eliminates internal and external blind holes, residual impurities, and oxide scale, preventing pollution and corrosion of the pipe and its surrounding environment, thus extending its service life. Traditionally, this is done manually using a cutter to remove the oxide layer; however, manual cutting is inefficient and physically demanding for workers. Utility Model Content

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Example: Please refer to Figure 1-3A rapid cutting device for the oxide layer of an electrofusion welding joint of a PE pipe includes a cutting table 1, a cutting assembly 2, and a first clamping assembly 3. The cutting table 1 is provided with a gasket 10 for placing a PE pipe 11. The first clamping assembly 3 clamps the PE pipe 11. Specifically, the first clamping assembly 3 includes a second cylinder 301 and a first clamping plate 302. The second cylinder 301 is fixedly connected to the cutting table 1, and its output shaft is connected to the first clamping plate 302. A baffle 6 is provided on the opposite side of the first clamping plate 302, and the baffle 6 is fixedly connected to the cutting table 1. The PE pipe 11 is positioned at the first clamping assembly 302. Between the clamping plate 302 and the baffle 6, the first clamping plate 302 is moved by the second cylinder 301, causing the first clamping plate 302 to press against the outer wall of the PE pipe 11, thereby fixing the PE pipe 11. Since the PE pipe 11 is relatively long, a second clamping assembly 7 is also provided on the cutting table 1 to achieve a better clamping effect. The second clamping assembly 7 includes a third cylinder 701 and a second clamping plate 702. The output shaft of the third cylinder 701 is connected to the second clamping plate 702, and the second clamping plate 702 is moved by the third cylinder 701, causing the second clamping plate 702 to press against the PE pipe 11. The outer wall of the PE pipe 11 is clamped by the second clamping plate 702 and the second clamping plate 702 respectively, making the PE pipe 11 more secure on the cutting table 1. In actual production, the length of the PE pipe 11 varies in different application scenarios. In order to accommodate PE pipes 11 of different lengths, the third cylinder 701 is slidably connected to the cutting table 1. Preferably, in order to achieve smooth sliding of the third cylinder 701, the cutting table 1 is provided with a slide rail 8. The bottom of the third cylinder 701 is connected to a slider that matches the slide rail 8. The slider is connected to a fourth cylinder 9. The fourth cylinder 9 is fixedly connected to the cutting table 1. Cylinder 9 drives the slider to move along the slide rail 8. The third cylinder 701 moves with the slider, thereby driving the second clamping plate 702 to move, so that the position of the second clamping plate 702 is adapted to the length of the PE pipe 11, thus meeting the usage requirements. The end faces of the first clamping plate 302, the baffle 6 and the second clamping plate 702 are all provided with anti-slip textures. The end faces with anti-slip textures are tangent to the outer wall of the PE pipe 11. Under the action of the anti-slip textures, the friction between the PE pipe 11 and the first clamping plate 302, the baffle 6 and the second clamping plate 702 is greater, thereby preventing the PE pipe 11 from rotating during cutting operations.The cutting assembly 2 includes a tool holder 201 and a blade 202 mounted on the tool holder 201. The blade 202 is used to cut the PE pipe 11. The cutting assembly 2 also includes a support plate 203, which is fixedly connected to the cutting table 1. A first cylinder 4 is connected to the tool holder 201. A support column 5 for mounting the first cylinder 4 is connected to the support plate 203. The first cylinder 4 is rotatably connected to the support column 5. A connecting lug is provided on the output shaft of the first cylinder 4, and the connecting lug is rotatably connected to the tool holder 201. The bottom of the tool holder 201 is rotatably connected to the support plate 203 through a rotating shaft. The tool holder 201 is pushed by the first cylinder 4, causing the tool holder 201 to rotate around the rotating shaft. The first cylinder 4 is tilted, and the tool holder 201 is set in an arc shape. The cutting table 1 is shaped such that when its output shaft drives the tool holder 201 to rotate, the tool holder 201 drives the blade 202 to move. The blade 202 moves along the direction of the PE pipe 11. The blade 202 is connected to a motor, which is fixedly connected to the tool holder 201. While the blade 202 moves, the motor drives the blade 202 to rotate, thereby quickly cutting the PE pipe 11. The cutting table 1 has a first clamping assembly 3 and a second clamping assembly 7 on both sides. The cutting groove is located in the middle of the cutting table 1. The structures of the first clamping assembly 3 and the second clamping assembly 7 on both sides are symmetrically arranged, so cutting operations can be performed on both sides of the cutting table. The blade 202 alternately cuts the PE pipe 11 on both sides, further improving the efficiency of the cutting operation.

[0017] The working principle of this embodiment is as follows: During use, the PE pipe 11 is placed on the gasket 10 and pushed to a suitable position so that the oxide layer of the PE pipe 11 is located on the other side of the blade 202. The fourth cylinder 9 is activated, which pushes the third cylinder 701 to move, causing the second clamping plate 702 to move to one-third of the position of the PE pipe 11. Simultaneously, the second cylinder 301 and the third cylinder 701 are activated. The second cylinder 301 pushes the first clamping plate 302 to move, and the third cylinder 701 pushes the second clamping plate 702 to move. Under the action of the first clamping plate 302 and the baffle 6, one end of the PE pipe 11 is clamped, and under the action of the second clamping plate 702 and the baffle 6, the other end of the PE pipe 11 is clamped. Then, the first cylinder 4 is activated, which drives the blade holder 201 to rotate around the axis, causing the blade 202 to move along the direction of the PE pipe 11, thereby rapidly cutting the PE pipe 11. Therefore, this utility model eliminates the need for manual cutting of the PE pipe 11, greatly improving work efficiency and reducing the labor intensity of workers.
