Therefore, a bending die with a multi-segment bending angle adjustment structure is urgently needed to address these issues. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bending die with a multi-segment bending angle adjustment structure. Its advantages include: enabling bending of workpieces at multiple angles to meet various bending requirements; and immediately stopping the machine when the die reaches the set bending angle to prevent over-bending and improve bending accuracy.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0016] The present invention is further configured such that a hook is threadedly connected to one side of both the material support block and the bending seat, and a second spring is hung inside the hook.
[0017] The above technical solutions enable the material support block to quickly return to its original position after bending, facilitating subsequent bending operations.
[0018] The present invention is further configured such that both outer walls of the bending seat are threadedly connected with fixing screws, and both outer walls of the bending seat are fixedly connected with limiting discs through the fixing screws, and one outer wall of the limiting disc is in contact with one outer wall of the material support block.

[0021] The above technical solutions enable precise adjustment of the bending angle of the entire mold, allowing for multiple bending operations at different angles on the workpiece, thus meeting people's bending needs for the workpiece.
[0022] The present invention is further configured such that a fixing nut is threadedly connected to the outer circumference of the threaded rod, and a fixing ring is fixedly connected to the top of the threaded rod.
[0023] The above technical solution allows for locking and fixing the threaded rod at any position using a fixing nut, ensuring that the threaded rod remains stable even after position adjustment.
[0024] The beneficial effects of this utility model are as follows:
[0025] 1. This utility model can effectively avoid excessive bending and improve the bending accuracy of the workpiece. Specifically, it is equipped with a connector, a touch switch, a material support block, and a bending head. The connector is fixedly connected to an external hydraulic cylinder, and the hydraulic cylinder is started. The hydraulic cylinder drives the upper die seat and the bending head to descend together, which can apply downward pressure to the surface of the workpiece. At this time, the two sets of material support blocks at the top of the bending seat will rotate. During the rotation, the workpiece will always be in contact with the surface of the material support block for bending. When the bending reaches the set angle, the connecting plate will be pressed against the touch switch on one side of the vertical plate, thereby disconnecting the touch switch and stopping the hydraulic cylinder that is electrically connected to it.
[0026] 2. In this utility model, the operator can adjust the position of the touch switch by sliding the threaded rod in the annular groove, thereby making the bending angle of the entire mold precisely adjustable, enabling the workpiece to be bent at multiple different angles to meet people's bending needs for the workpiece.

[0049] Working principle: When a workpiece needs to be bent in multiple segments, it can first be placed on the bending seat 6. Then, the connector 7 is fixedly connected to the external hydraulic cylinder, and the hydraulic cylinder is started. The hydraulic cylinder drives the upper die seat 2 and the bending head 27 to descend together, applying downward pressure to the surface of the workpiece. At this time, the two sets of material support blocks 8 at the top of the bending seat 6 will rotate. During the rotation, the workpiece will always be in contact with the surface of the material support block 8 for bending. When the bending reaches the set angle, the connecting plate 14 will press against the touch switch 31 on one side of the vertical plate 30, thereby disconnecting the touch switch 31 and stopping the hydraulic cylinder that is electrically connected to it, avoiding over-bending and improving the bending accuracy of the workpiece. At the same time, the operator can slide the threaded rod 18 in the annular groove 20 to adjust the position of the touch switch 31, thereby making the bending angle of the entire mold precisely adjustable, enabling multiple bending operations at different angles to meet people's bending needs.
