[0014] The following further describes the present utility model in conjunction with the embodiments and the drawings: First Embodiment

[0015] As Figure 1 and Figure 2 shown, the hydraulic pressing mechanism includes a base 1, a pressing oil cylinder 21, a rotating pressing arm, an upper push oil cylinder 41, a middle plate 52 and a push rod 51. The upper ends of the pressing oil cylinder 21 and the upper push oil cylinder 41 are both chamfered rectangular parallelepipeds, and the lower ends are both cylindrical. The base 1 is respectively provided with mounting holes matching the shapes and sizes of the lower ends of the pressing oil cylinder 21 and the upper push oil cylinder 41, and the lower ends of the pressing oil cylinder 21 and the upper push oil cylinder 41 are both embedded in the mounting holes of the base 1. In order to stably connect the pressing oil cylinder 21 and the upper push oil cylinder 41 to the base 1, the dimensions of the upper ends of the pressing oil cylinder 21 and the upper push oil cylinder 41 are larger than those of the lower ends, and through mounting holes are opened at the corners of the upper ends of the pressing oil cylinder 21 and the upper push oil cylinder 41, and threaded holes corresponding to the mounting holes are opened on the base 1. Bolts pass through the mounting holes of the pressing oil cylinder 21 and the upper push oil cylinder 41 and are tightened in the threaded holes of the base 1, so that both the pressing oil cylinder 21 and the upper push oil cylinder 41 are fixedly connected to the base 1.

[0016] The pressing oil cylinder 21 is provided with an oil pressure piston rod 22, and the upper end of the oil pressure piston rod 22 is connected to the rotating pressing arm. The rotating pressing arm includes a main body 31 and an arm rod 32. One side of the upper end of the rotating pressing arm extends laterally to form the arm rod 32, so that the main body 31 and the arm rod 32 are seamlessly connected into a whole. An installation hole is opened at the lower end of the main body 31 of the rotating pressing arm, an internal thread is provided in the installation hole, an external thread is provided at the upper end of the oil pressure piston rod 22, and the oil pressure piston rod 22 is in threaded fit connection with the rotating pressing arm. Starting the pressing oil cylinder 21 can make the oil pressure piston rod 22 stretch and retract, thereby driving the rotating pressing arm to move vertically downward or vertically upward.

[0017] The jacking oil cylinder 41 is provided with a jacking piston rod 42. A through installation hole is opened on the middle plate 52, an internal thread is provided in the installation hole, external threads are provided at the upper end of the jacking piston rod 42 and the lower end of the jacking rod 51, and the upper end of the jacking piston rod 42 and the lower end of the jacking rod 51 are both screwed into the installation hole of the middle plate 52. The jacking piston rod 42 and the jacking rod 51 are connected together through the middle plate 52. The length of the jacking rod 51 can be determined according to the height difference between the bottom of the arm rod 32 and the top of the jacking piston rod 42, and the stroke of the pistons of the jacking oil cylinder 41 and the pressing oil cylinder 21; while the length of the arm rod 32 is determined according to the distance between the outer side of the main body 31 of the rotating pressing arm and the jacking piston rod 42.

[0018] The processing process of the hydraulic pressing mechanism of this embodiment for the corners or lugs of the box body is as follows: First, move the box body close to the jacking rod 51, and extend a corner or lug of the box body into the space between the jacking rod 51 and the arm rod 32. Start the jacking oil cylinder 41 to make the jacking piston rod 42 drive the jacking rod 51 to move upward; and start the pressing oil cylinder 21 to make the oil pressure piston rod 22 drive the rotating pressing arm to move downward. Make the top of the jacking rod 51 and the bottom of the arm rod 32 press the corner or lug of the box body, so as to extrude and shape the corner or lug of the box body. Then change the movement directions of the pistons of the jacking oil cylinder 41 and the pressing oil cylinder 21, so that both the jacking rod 51 and the rotating pressing arm move away from the corner or lug of the box body, complete the processing of the corner or lug of the box body, and finally move the box body away.

[0019] Obviously, without departing from the principle described in the present invention, several improvements or modifications made should be regarded as the protection scope of the present invention.
