Based on the embodiments in the present application (for the convenience of description and understanding, the following is Figure 1 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0015] See also Figure 1-3The present application provides a technical solution for a connecting rod pressing mechanism of a flap-type automatic bending machine: a connecting rod pressing mechanism of a flap-type automatic bending machine, comprising a bed 1, two symmetrical columns 2 are arranged on the upper surface of the bed 1, a folding drive group 12 is arranged on the outer side of the column 2, the power output end of the folding drive group 12 passes through the column 2 and is connected to the bending lower wallboard 13, a folding tool 14 is installed on the bending lower wallboard 13, and also includes a pressing drive group 3, a pressing drive group 3 is arranged on the outer side of the column 2, and the pressing drive group 3 is arranged above the folding drive group 12, the power output end of the pressing drive group 3 passes through the column 2 and is connected to the bending lower wallboard 13 through the connecting rod mechanism 4 The bent upper wall panel 10 is connected, and the bent upper wall panel 10 is connected to the column 2 through a linear guide pair 11. The connecting rod mechanism 4 is mainly composed of an eccentric wheel disc 5, a first connecting shaft 6, a connecting disc 7, a second connecting shaft 8 and a bearing seat 9. The eccentric wheel disc 5 is installed on the power output end of the pressing drive group 3, and the eccentric wheel disc 5 is not concentric with the pressing drive group 3. The eccentric wheel disc 5 is rotatably connected to the connecting disc 7 through the first connecting shaft 6. The second connecting shaft 8 is rotatably connected to the connecting disc 7 at a position opposite to the first connecting shaft 6. The end of the second connecting shaft 8 facing away from the eccentric wheel disc 5 is connected to the bearing seat 9, and the bearing seat 9 is installed on the bent upper wall panel 10.

[0016] Specifically, the folding drive group 12 is mainly composed of a motor a and a reducer a. The reducer a is installed on the column 2, and the power output end of the reducer a is connected to the bent lower wall panel 13.

[0017] The column 2 is in a C-shape and can be formed by splicing and welding three plates. The column 2 is fixed to the bed 1 by bolts.

[0018] More specifically, the linear guide pair 11 is mainly composed of sliders and slide rails. There are two slide rails, which are vertically fixed on the columns 2 respectively. Each slide rail is slidably connected with at least one slider, and the slider is fixed to the bent upper wall panel 10 by bolts.

[0019] The first connecting shaft 6 is installed on the eccentric wheel disc 5, and is not concentric with the eccentric wheel disc 5. In this way, when the pressing drive group 3 is working, the eccentric wheel disc 5 drives the first connecting shaft 6 to rotate with the power output end of the pressing drive group 3 as the center. Since the second connecting shaft 8 on the connecting disk 7 is arranged opposite to the first connecting shaft 6, when the pressing drive group 3 is working, the first connecting shaft 6 can drive the connecting disk 7 and the second connecting shaft 8 to rotate, so that the second connecting shaft 8 drives the bearing seat 9 and the bending upper wall panel 10 to move along the linear guide pair 11, and through the forward or reverse rotation of the pressing drive group 3, the repeated up and down pressing movement of the bending upper wall panel 10 is realized.

[0020] Furthermore, the connecting disk 7 is mainly composed of a bearing 19, a bearing mounting plate and a disk body. The connecting disk 7 is provided with two oppositely arranged grooves, in which the bearing 19 is embedded, and the bearing 19 is fixed to the disk body through the bearing mounting plate.

[0021] Specifically, one of the bearings 19 is rotatably connected to the first connecting shaft 6 , and the other bearing 19 is rotatably connected to the second connecting shaft 8 .

[0022] This arrangement makes it easy for the first connecting shaft 6 to drive the connecting plate 7 and the second connecting shaft 8 to rotate, so that the second connecting shaft 8 drives the bearing seat 9 and the bent upper wall plate 10 to move along the linear guide pair 11.

[0023] Furthermore, the axes of the eccentric wheel disc 5, the first connecting shaft 6, the connecting disc 7 and the second connecting shaft 8 are all on the same plane.

[0024] Specifically, since the eccentric wheel disc 5 is not concentric with the power output end of the pressing drive group 3, the first connecting shaft 6 and the eccentric wheel disc 5 are not concentric to form a connecting rod structure, and the first connecting shaft 6 and the connecting disc 7 and the second connecting shaft 8 are not concentric to form a two-connecting rod structure.

[0025] Furthermore, the pressing drive group 3 is mainly composed of a motor 15 and a reducer 16 . The reducer 16 is installed on the column 2 , and the power output end of the reducer 16 is connected to the eccentric wheel 5 , and the power input end of the reducer 16 is connected to the motor 15 .

[0026] When in use: the motor 15 in the pressing drive group 3 rotates forward, and the motor 15 transmits power to the reducer 16, so that the reducer 16 transmits power to the eccentric wheel disc 5, and the eccentric wheel disc 5 drives the first connecting shaft 6 to rotate with the power output end of the pressing drive group 3 as the center. Since the second connecting shaft 8 on the connecting disk 7 is arranged opposite to the first connecting shaft 6, when the pressing drive group 3 is working, the first connecting shaft 6 can drive the connecting disk 7 and the second connecting shaft 8 to rotate, so that the second connecting shaft 8 drives the bearing seat 9 and the bending upper wall panel 10 to move downward along the linear guide pair 11 to press the plate, and then the motor a in the folding drive group 12 transmits power to the reducer a, and then the reducer a drives the bending lower wall panel 13 to rotate upward, thereby bending the plate.

[0027] Subsequently, the motor 15 in the pressing drive group 3 can be reversed to move the bent upper wall panel 10 upward along the linear guide rail pair 11 and reset.

[0028] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
