[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Example

[0029] To address the issue that existing bending equipment cannot handle, for example... Figure 1 The connector shown has shortcomings due to the subsequent bending process on one side after the sealing molding is completed. (Refer to...) Figure 2 and Figure 3 As shown, this application discloses a horizontal and vertical synchronous continuous bending mechanism, including a mold base 10 and a horizontal bending unit 20, a first vertical bending unit 30 and a second vertical bending unit 40 connected synchronously.

[0030] The mold base 10 is arranged along the left and right direction to support the movement of the material strip;

[0031] The transverse bending unit 20 is located at the rear of the die base 10 and is used to perform transverse stamping and bending on the workpiece.

[0032] The first vertical bending unit 30 is located at the rear of the horizontal bending unit 20 and is used to perform the first vertical punching and bending of the workpiece.

[0033] The second vertical bending unit 40 is located at the rear of the first vertical bending unit 30 and is used to perform a second vertical stamping and bending on the workpiece.

[0034] refer to Figure 2 As shown (where A is the initial state, A1 is the state of the workpiece blank after horizontal bending, A2 is the state of the workpiece blank after the first vertical bending, and A3 is the state of the workpiece blank after the second vertical bending), it should be noted that the horizontal bending unit 20, the first vertical bending unit 30, and the second vertical bending unit 40 of this application move synchronously. When the workpiece blank passes through the horizontal bending unit 20, the horizontal bending unit 20 will perform a horizontal bending on the workpiece blank in advance. When the workpiece blank passes through the first vertical bending unit 30, the first vertical bending unit 30 will perform a vertical bending on the workpiece blank for the first time. When the workpiece blank passes through the second vertical bending unit 40, the second vertical bending unit 40 will perform a vertical bending on the workpiece blank for the second time.

[0035] The transverse bending unit 20 includes a first support 21, a first inverted L-shaped bending block 22, and a first punch 23. The first support 21 is arranged on the rear side of the mold base 10 in the transverse direction, and a first dovetail groove 211 is provided above the first support 21 in the transverse direction. The bottom of the first inverted L-shaped bending block 22 is provided with a first dovetail slider 221 that slides in the first dovetail groove 211. A first inclined edge 222 is provided on the right side of the first inverted L-shaped bending block 22. The first punch 23 is located above the first inverted L-shaped bending block 22, and a second inclined edge 231 corresponding to the first inclined edge 222 is provided at the bottom of the first punch 23. Under the action of the first punch 23, the first inclined edge 222 and the second inclined edge 231 work together to drive the first inverted L-shaped bending block 22 to move in the transverse direction. While the first inverted L-shaped bending block 22 moves in the transverse direction, the workpiece blank will be pre-bent in the transverse direction.

[0036] As a necessary structure for the transverse bending unit 20, this application provides a clearance groove 11 at the rear of the mold base 10 to allow the first inverted L-shaped bending block 22 to move laterally within the clearance groove 11 under the action of the first punch 23.

[0037] In one specific embodiment, the first vertical bending unit 30 includes a second support 31, a second inverted L-shaped bending block 32, and a second punch 33. The second support 31 is arranged on the rear side of the mold base 10 along the vertical direction, and a second dovetail groove 311 is formed on the upper part of the second support 31 along the vertical direction. The bottom of the second inverted L-shaped bending block is provided with a second dovetail slider 321 that slides in the second dovetail groove 311. A third inclined side 322 is formed on the rear side of the second inverted L-shaped bending block 32. The second punch 33 is located above the second inverted L-shaped bending block 32, and a fourth inclined side 331 corresponding to the third inclined side 322 is formed on the bottom of the second punch 33. Under the action of the second punch 33, the third inclined side 322 and the fourth inclined side 331 cooperate to drive the second inverted L-shaped bending block 32 to move along the vertical direction. While the second inverted L-shaped bending block 32 moves vertically, the workpiece blank will be bent vertically for the first time.

[0038] The second vertical bending unit 40 includes a third support 41, a third inverted L-shaped bending block 42, and a third punch 43. The third support 41 is arranged vertically on the rear side of the mold base 10, and a third dovetail groove 411 is formed vertically above the third support 41. A third dovetail slider 421 is provided at the bottom of the third inverted L-shaped bending block 42 and slides in the third dovetail groove 411. A fifth inclined side 422 is formed on the rear side of the third inverted L-shaped bending block 42. The third punch 43 is located on the third vertical bending block 10. Above the three inverted L-shaped bending blocks 42, and at the bottom of the third punch 43, a sixth inclined side 431 corresponding to the fifth inclined side 422 is provided. Under the action of the third punch 43, the fifth inclined side 422 and the sixth inclined side 431 cooperate to drive the second inverted L-shaped bending block 32 to move vertically. While the third inverted L-shaped bending block 42 moves vertically, the workpiece blank will be bent vertically for the second time. Based on the second vertical bending unit 40, the workpiece is bent, and the entire bending work is completed.

[0039] In one specific embodiment, the first punch 23, the second punch 33, and the third punch 43 of this application are synchronously driven by an external drive source. In a specific implementation, the external drive source can be a lifting plate driven by a hydraulic cylinder, and the first punch 23, the second punch 33, and the third punch 43 can all be installed at the bottom of the lifting plate. Based on this, when the hydraulic cylinder drives the lifting plate to rise and fall, the first punch 23, the second punch 33, and the third punch 43 will move synchronously.

[0040] It should be emphasized that this application only illustrates one action. The subsequent reset of the first inverted L-shaped bending block 22, the second inverted L-shaped bending block 32, and the third inverted L-shaped bending block 42 are not the subject of this application. Of course, those skilled in the art can design their own based on the application documents according to their own needs, and will not elaborate further here.
