Two upright posts 231 are wound with second springs 237, one ends of the second springs 237 are fixedly connected to the upright posts 231, and the other ends of the second springs 237 are fixedly connected to the lantern ring 232.
In the process of machining the steel pipe, the upper end of the second baffle 21 abuts against the ascending end 235, the second spring 237 is in a natural state, the upper end of the third baffle 22 abuts against the pressing end 236, and the lower end of the third baffle 22 is separated from the steel pipe on the base 1. When the mounting plate 41 drives the second baffle plate 21 to ascend, the second baffle plate 21 pushes the ascending end 235 of the rotating plate 233 to ascend, and the steel pipe blocked by the second baffle plate 21 rolls and is fed to the baffle plate unit 512; the pressing end 236 of the rotating plate 233 will descend and press the third stopper 22 down, the third stopper 22 will block the other prepared steel pipe, and the second spring 237 will deform.
When the mounting plate 41 drives the second baffle 21 to descend, the second spring 237 gradually returns to a natural state and urges the third baffle 22 to ascend, and the upper end of the third baffle 22 pushes the pressing end 236 to ascend, so that the ascending end 235 always abuts against the upper end of the second baffle 21; the prepared steel pipe stopped by the lower end of the third baffle 22 will roll downward and be stopped by the lowered second baffle 21 for subsequent feeding of the prepared steel pipe.
The implementation principle of the machining device for the hydraulic cylinder body in the embodiment of the application is as follows: in the process of processing the steel pipe, the hydraulic cylinder 422 drives the mounting plate 41 to descend, the second baffle 21 descends synchronously, the second spring 237 urges the third baffle 22 to ascend, and the prepared steel pipe blocked by the third baffle 22 rolls downwards and is blocked by the descending second baffle 21; the first baffle 51 is inserted into the positioning groove 516 and blocks the steel pipe rolling on the base 1, the pressure plate 31 descends and presses against the steel pipe blocked by the first baffle 51, and at this time, the pressure plate 31 cannot descend continuously; the sliding post 322 on the mounting plate 41 will slide downward in the cavity 315 and the roller 324 on the pressing post 323 will roll downward on the inclined surface 317 so that the lower end of the pressing post 323 is turned upward.
In the process of turning the pressing column 323, the pressing column 323 always abuts against the first arc-shaped surface 318, and the first arc-shaped surface 318 urges the roller 324 on the pressing column 323 to always press against the inclined surface 317, so that the pressure plate 31 always presses the steel pipe against the base 1 and the first baffle 51. When the roller 324 rolls downwards on the inclined surface 317, the motor 431 drives the cutter heads 432 to rotate, and the plurality of cutter heads 432 saw the steel pipe simultaneously.
After the steel pipe is sawed, the hydraulic cylinder 422 drives the mounting plate 41 to ascend, the sliding column 322 slides upwards in the cavity 315, the roller 324 rolls upwards on the inclined surface 317, the connecting rope 321 is in a tightened state, and the mounting plate 41 drives the pressure plate 31 to ascend through the connecting rope 321 and keep away from the steel pipe which is sawed. Then, the first baffle 51 is separated from the steel pipe after sawing, so that the steel pipe rolls on the base 1 for blanking; the second baffle 21 will rise synchronously with the mounting plate 41, and the steel pipe blocked by the second baffle 21 will roll towards the first baffle 51; at the same time, the second baffle 21 will push the rotating plate 233 to turn over, so that the third baffle 22 descends to block other prepared steel pipes.
To sum up, this application has both realized the automatic feeding of steel pipe, has compressed tightly and automatic unloading voluntarily, makes a plurality of blade discs 432 saw cut the steel pipe simultaneously again to the machining efficiency of pneumatic cylinder 422 cylinder body has been improved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
