[0023] The present utility model will be further described below in conjunction with the accompanying drawings.

[0024] As Figure 1 and Figure 2 shown, the semi-circular plate cutting device of an embodiment of the present utility model includes a cylinder body 1, a support mechanism 2 and a cutter 3. The support mechanism 2 includes a support plate 21 and a support beam 22 for supporting the semi-circular plate 100. The support plate 21 is arranged vertically, the support beam 22 is arranged horizontally, both ends of the support beam 22 are respectively connected to the cylinder body 1 and the support plate 21, and the cutter 3 is slidably arranged on the surface of the cylinder body 1 and close to the support beam 22.

[0025] The support beam 22 arranged horizontally is respectively connected to the support plate 21 and the cylinder body 1 at both ends. The support beam 22 can provide good support for the semi-circular plate 100, so that the semi-circular plate 100 remains stable during the cutting process. The cutter 3 slidably arranged on the surface of the cylinder body 1 can move stably along the surface of the cylinder body 1, and use a high-temperature flame to complete the cutting operation on the semi-circular plate 100 during the movement. The semi-circular plate cutting device of this embodiment has a simple structure and is easy to use, and can quickly complete the cutting operation on the semi-circular plate 100.

[0026] Furthermore, the number of the support beams 22 is three, including two first cross beams 221 and one second cross beam 222. The two first cross beams 221 are at the same height, the second cross beam 222 is located above the first cross beams 221, and the two first cross beams 221 are symmetrically arranged with respect to the second cross beam 222. If only two first cross beams 221 are arranged, the semi-circular plate 100 can also be supported, but adding one second cross beam 222 can also support the top of the semi-circular plate 100, thereby improving the stability of the semi-circular plate 100. In this embodiment, the two first cross beams 221 are symmetrically arranged in space with respect to the second cross beam 222, so that the two first cross beams 221 and one second cross beam 222 can all have good contact with the semi-circular plate 100.

[0027] As Figure 3As shown, the support plate 21 includes a top plate 211, a connecting plate 212, and a bottom plate 213. The top plate 211 is triangular. One end of the first cross beam 221 and one end of the second cross beam 222 are both connected to the top plate 211. The two ends of the connecting plate 212 are respectively connected to the top plate 211 and the bottom plate 213. In this embodiment, the end faces of the two first cross beams 221 and one second cross beam 222 are distributed at the three interior angles of an isosceles triangle. Therefore, the shape of the top plate 211 is set to be triangular to reduce the area of the top plate 211 while avoiding interference with the placement of the semi-circular plate 100. The connecting plate 212 positions the top plate 211 at an appropriate height, enabling the first cross beam 221 and the second cross beam 222 to remain horizontal. The bottom plate 213 provides a large contact area between the support plate 21 and the ground, ensuring good stability.

[0028] As Figure 1 , Figure 2 and Figure 4 shown, a clamping assembly 4 is provided on the first cross beam 221. The clamping assembly 4 includes a mounting bracket 41, a handwheel 42, and a stud 43. The mounting bracket 41 is disposed on the first cross beam 221. The handwheel 42 is disposed at one end of the stud 43. The stud 43 is threadedly connected to the mounting bracket 41. After the semi-circular plate 100 is placed on the support beam 22, the edge of the semi-circular plate 100 will be caught in the mounting bracket 41. By turning the handwheel 42, the stud 43 rotates and moves on the mounting bracket 41, thereby clamping the edge of the semi-circular plate 100 and achieving a better fixing effect on the semi-circular plate 100. After the semi-circular plate 100 is cut, it is only necessary to loosen the handwheel 42 to remove the semi-circular plate 100, which is very convenient.

[0029] As Figure 4 shown, specifically, the mounting bracket 41 includes a first vertical plate 411, a cross plate 412, and a second vertical plate 413. The first vertical plate 411 and the second vertical plate 413 are disposed opposite to each other. The two sides of the cross plate 412 are respectively connected to the first vertical plate 411 and the second vertical plate 413. The first vertical plate 411 is connected to the first cross beam 221. The stud 43 is disposed on the second vertical plate 413. There is a large space between the first vertical plate 411 and the second vertical plate 413 for the edge of the semi-circular plate 100 to be caught. The stud 43 is threadedly connected to the second vertical plate 413, and the overall structure is simple and highly reliable.

[0030] In this embodiment, the cross sections of the first cross beam 221 and the second cross beam 222 are both rounded rectangles, making the surfaces of the first cross beam 221 and the second cross beam 222 in contact with the semi-circular plate 100 relatively smooth and avoiding scratching the semi-circular plate 100. In addition, using this shape for the first cross beam 221 instead of a circular tube also facilitates the reliable and stable connection of the first vertical plate 411 thereto.

[0031] In this embodiment, the first vertical plate 411 is arranged on the sides of the two first cross beams 221 away from each other. After the semi-circular plate 100 is placed, there is no obstruction when the hand wheel 42 is rotated, facilitating the operation.

[0032] Furthermore, the clamping assembly 4 further includes a buffer block 44, and the buffer block 44 is arranged at one end of the stud 43 away from the hand wheel 42. The buffer block 44 is made of an elastic material such as rubber. On the one hand, it prevents the stud 43 from directly contacting the semi-circular plate 100 and causing damage to the semi-circular plate 100. On the other hand, it can better clamp the semi-circular plate 100 through the deformation of the buffer block 44.

[0033] As Figure 1 shown, a guide rail 5 is further provided on the surface of the cylinder body 1, and a slider 6 is arranged on the guide rail 5. The cutter 3 is arranged on the slider 6. By providing the guide rail 5 and the slider 6, the cutter 3 can only move along a preset arc path, preventing the cutter 3 from shifting, ensuring the flatness of the cut, and reducing the operation difficulty.

[0034] As Figure 1 shown, a support base 7 is provided below the cylinder body 1. The support base 7 includes a base 71 and two support plates 72. The bottom of the support plate 72 is connected to the base 71, and the top of the support plate 72 is connected to the surface of the cylinder body 1. Since the surface of the cylinder body 1 is arc-shaped, directly placing it on the ground has poor stability. Therefore, the support base 7 is provided below it. The two support plates 72 arranged at intervals, together with the base 71, can provide stable and reliable support.

[0035] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
