[0038] Reference below Figure 1-Figure 3 An automatic pipe cutting machine is described in detail with a specific embodiment. It is worth noting that the following description is only an exemplary description and not a specific limitation of the utility model.

[0039] like Figure 1-Figure 3 As shown, an automatic pipe cutting machine includes a rotating mechanism, a feeding mechanism and a cutting mechanism.

[0040] Among them, the rotating mechanism includes a pneumatic chuck 100 and a stepper motor 110. The stepper motor 110 drives the pneumatic chuck 100 to rotate through a belt. The pneumatic chuck 100 is provided with an inlet 120 and an outlet 130. The loading mechanism is arranged on one side of the inlet 120, including a feeding assembly and a discharging assembly. The feeding assembly includes a trough 140 for placing pipe fittings, a feeding wheel 150 located on both sides of the trough 140, an abutting cylinder 160 for driving the feeding wheel 150 to abut the pipe fitting, and a feeding motor 170 for driving the feeding wheel 150 to rotate so that the pipe fitting moves forward from the inlet 120. The discharging assembly includes an inclined material rack 180 arranged on the side of the trough 140, and a pressing piece 190 and a pressing cylinder 200 are provided above the inclined material rack 180. A pipe fitting is allowed to pass between the material 190 and the inclined material rack 180. The pressing cylinder 200 is used to drive the pressing piece 190 to press the pipe fittings above the lowest pipe fitting of the inclined material rack 180. A material blocking rod 210 and a material blocking cylinder 220 are provided at the bottom of the inclined material rack 180. The material blocking cylinder 220 is used to drive the material blocking rod 210 to open and close to release the pipe fitting to the material trough 140. The cutting mechanism is arranged on one side of the discharge port 130, including a positioning assembly and a cutting assembly. The positioning assembly includes a positioning block 230 arranged opposite the discharge port 130, and a positioning cylinder 240 that drives the positioning block 230 to move to abut against the end of the pipe fitting. The cutting assembly includes a cutter 250 arranged on the side of the discharge port 130, and a cutting cylinder 260 that drives the cutter 250 to move. When in use, the pressing cylinder 200 drives the pressing piece 190 to press the pipes above the lowest pipe of the inclined material rack 180, the blocking cylinder 220 drives the blocking rod 210 to open and close so that the lowest pipe of the inclined material rack 180 is released to the material trough 140, the abutting cylinder 160 drives the feeding wheel 150 to abut the pipe, and the feeding motor 170 drives the feeding wheel 150 to rotate so that the pipe moves forward from the feeding port 120. It should be noted that the two ends of the pipes on the inclined material rack 180 should extend out of the two sides of the inclined material rack to ensure that the feeding wheel 150 can drive the pipe to be transported forward after the pipe enters the material trough 140. At the same time, the positioning cylinder 240 drives the The dynamic positioning block 230 moves to abut the end of the pipe fitting, so that the pipe fitting extends out of the discharge port 130 to a set distance, and then the pneumatic chuck 100 clamps the pipe, the abutting cylinder 160 drives the feeding wheel 150 to loosen, the positioning cylinder 240 drives the positioning block 230 to retract, the stepper motor 110 drives the pneumatic chuck 100 to rotate and thus drives the pipe fitting to rotate, and the cutting cylinder 260 drives the cutter 250 to move in the direction of the pipe fitting to cut the material. After the cutting is completed, the pneumatic chuck 100 stops rotating and loosens the pipe fitting, and the feeding assembly, the rotating mechanism, and the cutting mechanism repeat the above movement. After a pipe fitting is cut, the discharge assembly releases a pipe fitting again. Therefore, the cutting length of the pipe fitting can be set, and the automatic pipe cutting is completed, thereby improving production efficiency.

[0041] It should be noted that it also includes a machine 270, and the rotating mechanism, the feeding mechanism and the cutting mechanism are all arranged on the machine 270. The machine 270 is provided to facilitate the installation of the rotating mechanism, the feeding mechanism and the cutting mechanism. In addition, the cutting assembly also includes a cooling pipe 280 arranged on the side of the discharge port 130. The cooling pipe 280 can spray coolant for lubrication and cooling when cutting the pipe. Moreover, an inclined blanking plate 290 is provided below the discharge port 130. The inclined blanking plate 290 can guide the fallen pipe fittings to the designated position after the pipe cutting is completed, so as to prevent the pipe fittings from piling up and affecting the subsequent processing. Furthermore, a material frame 300 is provided at the output end of the blanking plate 290. The material frame 300 is provided to collect the cut pipe fittings for easy transportation to the next process.

[0042] like Figure 2 As shown, the pressing piece 190 is a pressing rod, which is arranged in a direction perpendicular to the pipe fittings, and the bottom surface of the pressing rod is parallel to the inclined material rack 180. This arrangement facilitates the pressing cylinder 200 to drive the pressing piece 190 to press the pipe fittings above the bottom pipe fitting of the inclined material rack 180.

[0043] Specifically, Figure 1 As shown, two feeding wheels 150 are respectively provided on both sides of the material trough 140. The two feeding wheels 150 are respectively provided to facilitate the conveying of the pipe fittings to the feeding port and ensure accurate guiding.

[0044] like Figure 3 As shown, a slider 310 is provided at the output end of the abutting cylinder 160, and the feeding wheel 150 is mounted on the slider 310. Such a configuration is conducive to the installation of the feeding wheel 150. Specifically, the feeding motor 170 is mounted on one of the feeding wheels 150. In this way, only one feeding motor 170 is required to drive the pipe to move forward, saving costs while preventing the feeding wheel 150 from rotating asynchronously. It can be understood that an arc groove 320 is provided on the side of the feeding wheel 150 to cooperate with the pipe. The arc groove 320 provided on the side of the feeding wheel 150 is conducive to cooperation with the pipe, ensuring that the pipe is separated from the trough 140 during transportation and processing.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
