[0028] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.

[0029] like Figures 1-4 As shown, a pneumatic pipe cutting machine includes a carrier 1 that enables the pneumatic pipe cutting machine to stably cut pipes. Positioning components 2 are arranged on both sides of the carrier 1 to limit the pipes to be cut and move them horizontally in a quantitative manner. A cutting component 3 is arranged above the carrier 1 to cut the pipes moved into place according to production needs.

[0030] In this embodiment:

[0031] The carrier 1 includes a platform 101, in which a chip removal groove 102 is integrally formed. A first arc-shaped frame 103 is fixedly connected to the upper side of the platform 101, and a first rotating rod 104 is movably installed in the first arc-shaped frame 103; the first arc-shaped frame 103 is rotatably connected to the first rotating rod 104;

[0032] Parts of the components are mounted on the platform 101 to ensure stable operation of the pneumatic pipe cutting machine. The chip removal groove 102 facilitates the removal of debris generated by pipe cutting from the platform 101. The rotatable first rotating rod 104 installed in the first arc-shaped frame 103 appropriately limits the position of the pipe on the platform 101 and reduces friction between the pipe and the platform 101 during rotation.

[0033] In this embodiment:

[0034] The positioning assembly 2 includes a blocking member that can make the distance of the pipe material's single lateral movement in the pneumatic pipe cutting machine just meet the processing needs, a limiting member that can limit the pipe material and drive it to rotate and move horizontally, and a bearing member that can adjust the positions of the blocking member and the limiting member together. The bearing member includes a transverse rod 201 movably mounted under the platform 101, a transverse cylinder 202 is fixedly mounted on one side of the platform 101, and the blocking member includes a first support 203 fixedly connected to one end of the transverse rod 201, a vertical frame 204 is movably connected to the first support 203, a conical blocking block 205 is movably connected to the upper end of the vertical frame 204, and a locking knob 206 is fixedly connected to one side of the first support 203. The limiting member includes a second support 207 fixedly connected to one end of the transverse rod 201, a vertical rod 208 is fixedly connected to the upper side of the second support 207, a second arc frame 209 is fixedly connected between the vertical rods 208, and a second rotating rod 210 is movably installed in the second arc frame 209. The limiting member also includes a top plate 211 fixedly connected to the upper end of the vertical rod 208, a vertical cylinder 212 is fixedly installed on the top plate 211, and a lifting frame 213 is fixedly connected to the telescopic end of the vertical cylinder 212. A rotating shaft 214 is movably installed in the lifting frame 213, one end of the rotating shaft 214 is fixedly connected to a motor 215, and the outer side of the rotating shaft 214 is fixedly connected to a spiral feeding sleeve 216;

[0035] The platform 101 is slidably connected to the transverse rod 201, the first support 203 is slidably connected to the vertical frame 204, the vertical frame 204 is rotatably connected to the conical block 205, the second arc frame 209 is rotatably connected to the second rotating rod 210, the vertical rod 208 is slidably connected to the lifting frame 213, and the lifting frame 213 is rotatably connected to the rotating shaft 214;

[0036] The first support 203 and the second support 207 are installed and driven to move together on both sides of the platform 101 through the transverse rod 201, and the position of the second support 207 on one side of the platform 101 is directly adjusted by the operation of the transverse cylinder 202, and the position of the first support 203 on the other side of the platform 101 is indirectly adjusted synchronously. The conical block 205 is installed through the vertical frame 204 that can be raised and lowered relative to the first support 203, and the conical block 205 abuts against one end of the pipe to block the lateral movement of the pipe. The lifting of the vertical frame 204 relative to the first support 203 is limited by the locking knob 206. The second arc frame 209, the top plate 211, and the lifting frame 213 can be located at different heights directly above the second support 207 through the vertical rod 208 installed above the second support 207. The second curved frame 209 supports part of the pipe body to be cut to prevent one end of the pipe from tilting when the pipe moves horizontally. The second rotatable rotating rod 210 installed in the second curved frame 209 is used to appropriately limit the pipe on the second curved frame 209 and reduce the friction between the pipe and the second curved frame 209 when the pipe rotates. The vertical cylinder 212 installed above the top plate 211 drives the lifting frame 213 to rise and fall relative to the second curved frame 209. The lifting frame 213 is installed on the rotating shaft 214 with a spiral feeding sleeve 216 connected to the outer side. The motor 215 drives the rotating shaft 214 to rotate relative to the lifting frame 213. The spiral feeding sleeve 216 that can contact the pipe transmits the rotation of the rotating shaft 214 to the pipe, thereby driving the pipe to rotate and enabling the pipe to move horizontally.

[0037] In this embodiment:

[0038] The cutting assembly 3 includes a loading frame 301 movably mounted on the platform 101, a bracket 302 fixedly connected to the rear of the platform 101, an inclined cylinder 303 is provided between the loading frame 301 and the bracket 302, and a cutting machine 304 is fixedly mounted on the loading frame 301; the platform 101 and the loading frame 301 are rotatably connected;

[0039] The cutting machine 304 is installed through the loading frame 301 and driven to rotate relative to the platform 101. The inclined cylinder 303 is installed through the bracket 302. The loading frame 301 is driven to rotate relative to the platform 101 by the inclined cylinder 303. The cutting machine 304 contacts the pipe moved onto the platform 101 and cuts it.

[0040] Working principle:

[0041] When the pneumatic pipe cutting machine is installed and used for the production of metal doors, the pipe to be cut needs to be placed horizontally on the table 101 and the second arc frame 209. Then, according to the height of the axis of the pipe, the locking knob 206 is loosened and the height of the conical block 205 is adjusted. After the axis of the pipe and the conical block 205 coincide, the locking knob 206 is tightened. After that, after one end of the pipe is tightly against the conical block 205, the transverse cylinder 202 is used to drive the transverse rod 201 to move horizontally until the distance from the position where the pipe can contact the cutting machine 304 to the end where the pipe contacts the conical block 205 is equal to the pipe length required for the production of metal doors.

[0042] After the above adjustment work is completed, the vertical cylinder 212 can be operated to drive the lifting frame 213 to move down until the spiral feeding sleeve 216 is tightly against the upper edge of the pipe, thereby cooperating with the platform 101, the first arc frame 103, the conical block 205, the second arc frame 209 and other components to limit the pipe. After that, the inclined cylinder 303 can be operated to adjust the position of the running cutting machine 304, so that the cutting machine 304 is close to the pipe and cuts it. After a single cutting is completed, the cutting machine 304 can be reset, and after removing the cut part of the pipe, the motor 215 is operated to drive the rotating shaft 214 to rotate. Under the friction between the spiral feeding sleeve 216 and the pipe, the spiral feeding sleeve 216 will drive the pipe to rotate and move horizontally towards the conical block 205. After the pipe is tightly against the conical block 205 again, the position of the cutting machine 304 can be directly adjusted to cut the moved pipe again.

[0043] Before the cutting machine 304 cuts the moved pipe, the motor 215 can be used to continuously drive the rotating shaft 214 to rotate. Since the conical block 205 will prevent the pipe from moving laterally, the spiral feed sleeve 216 can only drive the pipe to rotate. When the continuously rotating pipe is cut, the pipe cut will be smoother and less deformed.

[0044] The preferred embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of technicians in the relevant technical field without departing from the purpose of the present invention.
