[0015] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0016] Please refer to Figs. 1-3 In the embodiments of the utility model, a novel bending center power hinge knife comprises a main body 1, a containing groove is formed on the lower side of the main body 1, a rotating handle 3 is rotatably installed on the inner side of the containing groove, a presser 4 is integrally formed at the bottom end of the rotating handle 3, a spring groove 13 recessed upward is formed at the bottom end of the main body 1, a tension spring 9 is hooked on the inner wall of the spring groove 13, the bottom end of the tension spring 9 is hooked with the top end of the rotating handle 3, an outer shell 5 is fixedly installed on the outer side of the main body 1 through bolts, a connecting rod mechanism connected with the rotating handle 3 is slidingly connected on the outer shell 5, and the connecting rod mechanism is used to drive the rotating handle 3 and the presser 4 to rotate upward or reset downward.

[0017] In this embodiment: First, the output end of the drive mechanism (e.g., an electric push cylinder, the output end of which is connected to the slot 8) is connected to the input end of the linkage mechanism. When pressing the workpiece below the edge, the drive mechanism is activated, which drives the linkage mechanism to move. When the linkage mechanism moves, the rotating handle 3 and the pressure knife 4 move from their initial positions ( Fig. 1 As shown, rotate upwards to make the pressure knife 4 rotate from a horizontal state to a vertical state until the bottom end of the main body 1 moves below the edge of the workpiece. At this time, the drive mechanism resets upwards, and the tension spring 9 resets, so that the rotating handle 3 and the pressure knife 4 can rotate to the initial position. When the pressure knife 4 is reset to the initial position, the bottom end of the pressure knife 4 has not yet contacted the top end of the workpiece. Therefore, after the pressure knife 4 is reset, the main body 1 continues to move downwards until the pressure knife 4 presses the bottom of the edge of the workpiece.

[0018] It should be noted that the lifting power of the main body 1 comes from another electric push cylinder connected to it.

[0019] Please refer to this carefully. Fig. 2 and Fig. 3 The linkage mechanism includes a vertically formed groove 6 on the outer shell 5, a sliding block 7 slidably connected to the inner wall of the groove 6, the sliding block 7 extending through the outside of the groove 6, and a downwardly recessed slot 8 at the top of the sliding block 7. The linkage mechanism also includes a connecting rod 10 rotatably connected to one end of the sliding block 7, the bottom end of the connecting rod 10 being rotatably connected to the rotating handle 3 via a connecting pin 12, and the rotating handle 3 being rotatably connected to the main body 1 via a rotating pin 11.

[0020] In this embodiment: when the electric push rod connected to the sliding block 7 extends, the sliding block 7 moves downward under force and slides along the slide groove 6. At this time, the sliding block 7 presses the connecting rod 10, and the pressed connecting rod 10 moves downward. Since the connecting rod 10 is in an inclined state, the connecting rod 10 applies a rotational force to the rotating handle 3 when it moves downward. The rotating handle 3 rotates upward around the rotating pin 11, thereby realizing the rotation of the pressure knife 4 from the horizontal state to the vertical state. At this time, the tension spring 9 deforms. When the pressure knife 4 passes the edge of the workpiece, the pressure applied to the sliding block 7 is removed, and the tension spring 9 returns to its original position, realizing the return of the pressure knife 4 from the vertical state to the horizontal state, thus achieving the pressing of the lower edge of the workpiece.

[0021] Please refer to this carefully. Fig. 3 A docking groove 14 is provided at the rotatable connection between the connecting rod 10 and the sliding block 7, and a protective plate 2 is installed on the main body 1 to seal the spring groove 13.

[0022] In this embodiment: This design facilitates the connection between the sliding block 7 and the connecting rod 10 via the docking groove 14;

[0023] The design of the protective plate 2 can protect the tension spring 9.

[0024] The above merely describes a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent substitutions or changes within the technical range disclosed by the present application, which should be covered within the scope of protection of the present application.
