[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0021] Reference Figures 1-2 The bending center pressing mechanism of this utility model is implemented in the following embodiments: The bending center pressing mechanism of this embodiment includes: a base assembly 100, a pressing knife assembly 200, and a pressing drive assembly.

[0022] In this embodiment, the base assembly 100 includes a fixed base 110 and a swing base 120. The swing base 120 is located above the fixed base 110, and the rear end of the swing base 120 is hinged to the rear end of the fixed base 110. In this embodiment, the rear end of the swing base 120 is hinged to the rear end of the fixed base 110 by a first hinge shaft 130 along the left-right direction, so that the front part of the swing base 120 can swing up and down relative to the fixed base 110.

[0023] like Figure 2 As shown, the pressing knife assembly 200 in this embodiment includes an upper pressing knife module 210 and a lower pressing knife module 220. The upper pressing knife module 210 is installed at the front end of the swing seat 120, and the lower pressing knife module 220 is installed at the front end of the fixed base 110. The upper pressing knife module 210 and the lower pressing knife module 220 are arranged vertically opposite each other. In this embodiment, the upper pressing knife module 210 and the lower pressing knife module 220 abut against the top and bottom surfaces of the plate respectively to achieve pressing of the plate.

[0024] The upper pressing module 210 includes multiple upper cutting bodies arranged in the left-right direction. The corresponding number of upper cutting bodies can be selected and combined according to the bending requirements. The lower pressing module 220 includes lower cutting bodies arranged in the left-right direction.

[0025] In this embodiment, the pressing drive assembly is connected to the swing seat 120. The pressing drive assembly is used to drive the swing seat 120 to swing up and down relative to the fixed base 110, so as to drive the upper pressing knife module 210 to move closer to or away from the lower pressing knife module 220. When it is necessary to press the plate, first control the upper pressing knife module 210 to move away from the lower pressing knife module 220, place the plate between the upper pressing knife module 210 and the lower pressing knife module 220, and then control the upper pressing knife module 210 to move closer to the lower pressing knife module 220 to press the plate.

[0026] This invention achieves the pressing and releasing of the plate by swinging the swing seat 120 up and down. It can use the gravity of the swing seat 120 to press the plate, which makes the pressing effect of the plate more stable.

In this embodiment, the rotation drive structure 330 is used to drive the second transmission arm 320 to rotate, so as to drive the swing seat 120 to swing up and down relative to the fixed base 110, thereby improving the stability of the drive. In this embodiment, the rotation drive structure 330 adopts a servo motor.

[0028] Furthermore, the fixed base 110 includes a base plate 111, a front plate 112, and two side plate 113. The two side plate 113 are vertically connected to the left and right ends of the base plate 111, and the front plate 112 is vertically connected to the front end of the base plate 111. In this embodiment, the pressing knife module 220 is installed on the top of the front plate 112.

[0029] The swing seat 120 includes a pressure frame 121 and two swing arms 122. The two swing arms 122 are respectively connected to the left and right ends of the pressure frame 121. The two swing arms 122 are inclined backward and downward. The upper pressure knife module 210 is installed at the bottom of the pressure frame 121. The rear ends of the two swing arms 122 are respectively hinged to the upper part of the two side plate seats 113. In this way, a space for installing the bending knife mechanism is formed between the swing seat 120 and the fixed base 110, which also improves the swing stability of the swing seat 120.

[0030] In this embodiment, the first transmission arm 310 is hinged to the pressure frame 121, and the second transmission arm 320 is hinged to the side plate seat 113.

[0031] And, as Figure 2 As shown, the first transmission arm 310 in this embodiment has an upper hinge arm 311 and a lower hinge arm 312 that bend forward at its upper and lower ends, respectively. The upper hinge arm 311 is hinged to the pressure frame 121 via a second hinge shaft 340 extending in the left-right direction. The lower hinge arm 312 is hinged to the second transmission arm 320 via a third hinge shaft 350 extending in the left-right direction. The second transmission arm 320 is hinged to the side plate seat 113 via a fourth hinge shaft 360 extending in the left-right direction.

[0032] To improve the structural strength of the swing seat 120, this embodiment has at least one crossbeam 123 connected between the two swing arms 122.

[0033] Furthermore, in order to improve the structural strength of the fixed base 110, a first reinforcing seat 114 is connected between the two side plate seats 113 and the base plate seat 111, and a hinge seat 115 is provided between the first reinforcing seat 114 and the side plate seats 113. The swing arm 122 is hinged to the hinge seat 115 to improve the stability of the connection between the swing seat 120 and the fixed base 110.

[0034] Furthermore, a plurality of second reinforcing seats 116 are connected between the front plate seat 112 and the bottom plate seat 111. The plurality of second reinforcing seats 116 are arranged at intervals in the left and right direction to reinforce the connection between the front plate seat 112 and the bottom plate seat 111.

[0035] In order to improve the balance of the swing of the swing seat 120, two swing drive modules 300 are provided in this embodiment. The two swing drive modules 300 are arranged at intervals in the left and right direction on the opposite side between the two side plate seats 113 and the two swing arms 122. The two swing drive modules 300 are used to drive the swing seat 120 to swing synchronously.
