The lever type station lifting mechanism has the following working principle: as shown in fig. 2, when the piston rod of the cylinder 9 extends outwards, the translational slider 7 is driven to push forwards, the translational slider 7 pushes forwards through the middle rotating shaft 70 to force the connecting rod 5 and the swing seat 6 to slowly rise, when the connecting rod 5 and the swing seat 6 reach a vertical state, the guide plate 2 extends to the highest point, and because the component is in a vertical state, a self-locking effect is achieved, a four-two-poking jack effect is achieved for the stress of the cylinder 9, and the up-and-down motion of the whole mechanism is more stable and effective. As shown in fig. 3, the piston rod of the cylinder 9 retracts, and the guide plate 2 is at the lowest point, i.e. one lifting action is completed.

Because the cylinder 9 needs to swing, consequently the rear portion of cylinder 9 needs rotatable setting, therefore the rear portion of cylinder 9 can directly articulate at roof 11, also can be connected with back hanging seat 10 on roof 11, and back hanging seat 10 is articulated through the rear portion of back pivot with cylinder 9, and the rotation of certain angle can be realized to the back pivot on the back hanging seat 10 by cylinder 9 to satisfy the swing requirement of cylinder 9 during operation.

The working principle of the lever-type station lifting mechanism is described in detail below by taking a forming device as an example.

As shown in fig. 1, the forming device includes an upper forming die 14 and a lower forming die 13, and certainly includes the lever-type station lifting mechanism described above, the lever-type station lifting mechanism includes a guide plate 2, a box body 1 and a cylinder 9, the lower forming die 13 is connected to the guide plate 2, a left side plate 12 and a right side plate 12 are connected to the box body 1, an upper die holder 15 is installed on the side plates 12, the upper forming die 14 is connected to the upper die holder 15, the guide plate 2 is connected to a guide shaft 3, the box body 1 is installed with a guide sleeve 4, the guide shaft 3 is movably arranged in the guide sleeve 4, a hinge holder 20 is connected to the bottom of the guide plate 2, the hinge holder 20 is hinged to the upper end of a connecting rod 5 through an upper rotating shaft 51, the lower end of the connecting rod 5 is hinged to the upper end of a swing holder 6 through a middle rotating shaft 70, the lower end of the swing holder 6 is hinged to the box body 1 through a lower rotating shaft 61, a translation slider 7 is hinged to the middle rotating shaft 70, the translation slider 7 is connected to the piston rod of the cylinder 9, the rear portion of the cylinder 9 is hinged to a top plate 11, and the top plate 11 is connected to the box body 1.

The working principle of the lever type station lifting mechanism is described in detail above, and the detailed description is omitted here. When the guide plate 2 of the lever type station lifting mechanism moves up and down, the guide plate 2 drives the lower forming die 13 to move up and down, so that the lower forming die 13 and the upper forming die 14 are matched. Because the lever type station lifting mechanism has high bearing capacity, the upper forming die 14 and the lower forming die 13 can be completely closed, and the pressing is compact enough, so that an ideal forming effect is achieved.
