DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described below in combination with the drawings in the embodiments of the present application.

[0026] Please refer to Figures 1-6 , the present application provides a galvanized pipe cutting device, which comprises a cutting assembly 10 and a positioning assembly 20.

[0027] Embodiment one

[0028] Please refer to Figure 1 ,Figure 5 and Figure 6 , the cutting assembly 10 comprises an operating table 110, a cutting part 120 is installed on the operating table 110, a cutting seat 130 is installed on the operating table 110 directly below the cutting end of the cutting part 120, a downwardly inclined discharge plate 140 is arranged between the side of the cutting seat 130 away from the installation box body 210 and the operating table 110, a loading box 150 is installed on the side wall of the operating table 110 at the end of the discharge plate 140, and a dust removal box 151 with a hollow bottom is stacked inside the loading box 150; wherein the galvanized pipe body 30 is placed on the cutting seat 130, then the cutting part 120 is started, the cutting part 120 is lowered to cut the galvanized pipe body 30, and the cut galvanized pipe body 30 falls along the discharge plate 140 into the dust removal box 151, while the debris generated during cutting of the galvanized pipe body 30 enters the loading box 150 through the hollow bottom when falling. The specific structure and cutting principle of the cutting part 120 are prior art, which will not be described in detail here.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 , the positioning assembly 20 comprises an installation box body 210, the installation box body 210 is installed on the operating table 110, a driving part 220 is installed inside the installation box body 210, and two rollable limiting parts 230 are installed at both ends of the installation box body 210, the bottom end of the rollable limiting part 230 away from the cutting part 120 is connected with the driving part 220, and the driving part 220 drives the rollable limiting part 230 to move. Wherein, when cutting the galvanized pipe body 30, the galvanized pipe body 30 is placed on the two rollable limiting parts 230 and extends into the cutting seat 130, the cutting part 120 is started to cut it, when the galvanized pipe body 30 needs to be cut to a shorter length, the driving part 220 is started to drive one of the rollable limiting parts 230 to move, and the other rollable limiting part 230 is approached, so that the shorter galvanized pipe body 30 can still be positioned during cutting. The distance between the two rollable limiting parts 230 can be shortened or the side length can be adjusted by driving one of the rollable limiting parts 230 to move by the driving part 220, so that the positioning distance can be adjusted according to the actual length of the galvanized pipe body 30, preventing the galvanized pipe body 30 from being effectively positioned due to its shorter length. By arranging the rollable limiting part 230, the galvanized pipe body 30 can still be pushed forward to realize cutting without loosening the galvanized pipe body 30 during positioning, thereby improving the cutting efficiency of the galvanized pipe body 30.

[0030] In this embodiment, the two rollable limiting members 230 include a base portion 231 and a rollable pressing portion 232. The base portion 231 is installed at both ends of the mounting box 210, and the rollable pressing portion 232 is installed directly above the base portion 231. The bottom end of the base portion 231 away from the cutting member 120 is connected to the driving member 220. The base portion 231 includes a mounting plate 2311. The mounting plate 2311 near the cutting member 120 is fixedly connected to the side wall of the mounting box 210, and the mounting plate 2311 away from the cutting member 120 is slidably connected to the mounting box 210. Vertical plates 2312 are fixedly connected to both ends of the two mounting plates 2311 respectively. The two vertical plates 2312 are rotatably connected to a limiting roller 2313a with a concave middle and convex ends on opposite surfaces. The rollable clamping part 232 includes a U-shaped frame 2321, which is mounted on a mounting plate 2311. A cylinder 2322 is mounted on the top of the U-shaped frame 2321. The output end of the cylinder 2322 movably passes through the top wall of the U-shaped frame 2321 and is fixedly connected to a U-shaped seat 2323. A clamping roller 2324 with a concave center and convex ends is rotatably connected inside the U-shaped seat 2323. The driving component 220 includes a motor 221, which is mounted on the side wall of the mounting box 210 away from the cutting component 120. A long screw 222 is fixedly connected to the output end of the motor 221. The other end of the long screw 222 movably passes through the side wall of the mounting box 210 and is rotatably connected to the inner wall of the other side of the mounting box 210. The bottom of the mounting plate 2311 away from the cutting component 120 is screwed to the long screw 222. A threaded sleeve 260 is fixedly connected to the bottom of a mounting plate 2311 located away from the cutting component 120. The threaded sleeve 260 is screwed to a long screw 222. When it is necessary to change the limiting distance, the motor 221 is started, causing the long screw 222 to rotate. This causes the threaded sleeve 260 to move on the long screw 222, thus moving the rolling limiting component 230. This changes the distance between the two rolling limiting components 230, placing the galvanized pipe body 30 on the two limiting rollers 2313a. Then, the two cylinders 2322 are activated, causing the pressing roller 2324 to press against the upper surface of the galvanized pipe body 30. Since both the limiting rollers 2313a and the pressing roller 2324 are rotatable, the galvanized pipe body 30 can be pushed directly without needing to be released, thus improving cutting efficiency.

[0031] In this embodiment, strip plates 250 are fixedly connected to both side walls of the mounting box 210. Connecting blocks 270 are fixedly connected to both ends of the bottom of a mounting plate 2311 away from the cutting member 120. Both connecting blocks 270 have grooves that mate with the two strip plates 250. The cooperation between the strip plates 250 and the grooves makes the rolling limiting member 230 more stable during movement.

[0032] Example 2

[0033] The difference from Example 1 is that:

[0034] Please see Figure 1 , Figure 2 and Figure 4 Two mounting plates 2311 are fixedly connected with positioning seats 2313b with V-shaped grooves. In particular, replacing the limiting roller 2313a with the positioning seat 2313b makes the galvanized pipe body 30 more stable during positioning.

[0035] Working principle of the galvanized pipe cutting device:

[0036] When cutting the galvanized pipe body 30, the galvanized pipe body 30 is placed on two rolling limiting members 230 and extended into the cutting seat 130. The cutting member 120 is then activated to cut it. When the galvanized pipe body 30 is cut to a shorter length and still needs to be cut, the driving member 220 is activated, allowing one rolling limiting member 230 to move closer to the other rolling limiting member 230. This ensures that the shorter galvanized pipe body 30 can still be limited during cutting. By driving one rolling limiting member 230 to move, the distance between the two rolling limiting members 230 can be shortened or lengthened. This allows the positioning distance to be adjusted according to the actual length of the galvanized pipe body 30, preventing ineffective positioning due to a short galvanized pipe body 30. By setting the rolling limiter 230, when limiting the galvanized pipe body 30, the galvanized pipe body 30 can still be pushed forward to achieve cutting without loosening the galvanized pipe body 30, thereby improving the cutting efficiency of the galvanized pipe body 30.

[0037] It should be noted that the specific model specifications of motor 221 and cylinder 2322 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] The power supply and operating principle of the motor 221 and cylinder 2322 are clear to those skilled in the art and will not be described in detail here.
