[0002] A bending machine is a machine capable of bending thin plates, and its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket, and the workbench is composed of a base and a pressing plate. Especially for some plate parts that need to be bent, the use of a bending machine is indispensable.

[0003] Some existing bending machines, in order to be applicable to different models of plate parts or the plate parts need to be bent to different degrees, most of their bending bases and bending heads can be disassembled and replaced. However, most of their bending bases are limited and fixed by screws, and they do not have a good locking structure. When disassembling and replacing, it is necessary to loosen the screws one by one, which is rather troublesome and inconvenient, affecting the work efficiency. To sum up, the existing bending machines still have the following problems:

[0008] Preferably, the locking device includes an adjusting frame and a servo motor. Chute grooves are formed in the left and right fronts of the front end of the adjusting frame. Sliders are installed in both chute grooves. Locking blocks are installed at the rear ends of both sliders. Thread grooves are formed in the front parts of the right ends of both sliders. A support base is installed at the lower right end of the adjusting frame. The output end of the servo motor is fixedly installed with a forward and reverse screw rod. The forward and reverse screw rod is installed between the left inner wall and the right inner wall of the adjusting frame. The two sliders are respectively installed on the left part and the right part of the outer surface of the forward and reverse screw rod through the thread grooves. The servo motor is installed on the upper end of the support base. The adjusting frame is installed at the front part of the upper end of the base. The servo motor drives the forward and reverse screw rod on it to rotate between the left inner wall and the right inner wall of the adjusting frame. When the forward and reverse screw rod rotates, it will drive the two sliders to move relatively in the chute grooves, thereby driving the locking blocks on them to insert into the locking grooves on the bending seat, so as to quickly lock the bending seat.

[0009] Preferably, the bending device includes a connecting plate and a bending head. A connecting groove is formed at the lower end of the connecting plate. A connecting block is installed in the middle of the upper end of the bending head. The bending head is installed at the lower end of the connecting plate. The connecting plate is fixedly installed on the output end of the hydraulic cylinder. The bending head can be quickly clamped into the connecting groove by the connecting block on it, and then the screws on the connecting plate are screwed into the bending head to fix the bending head. Therefore, loosening the screws can disassemble the bending head, enabling the device to replace the bent components according to the needs of the plate bending.

[0010] Preferably, a limiting groove is formed in the middle of the upper end of the base. Locking grooves are formed in the front parts of the left and right ends of the bending seat. A bending groove is formed in the middle of the upper end of the bending seat. The bending seat is placed in the limiting groove and locked with the locking block, effectively improving the stability of the bending seat after installation.

[0011] Preferably, both the connecting groove and the connecting block are in a T shape.

[0012] Preferably, the locking block and the locking groove are of the same size and their positions correspond to each other left and right.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

The two sliders are respectively installed on the positive thread and the reverse thread of the forward and reverse screw rod through the thread grooves on them. Therefore, when the forward and reverse screw rod rotates, it will drive the two sliders to move relatively in the chute grooves, thereby driving the locking blocks on them to insert into the locking grooves on the bending seat, so as to quickly lock the bending seat. In addition, driving the forward and reverse screw rod in the reverse direction by the servo motor will drive the locking block to withdraw from the locking groove, which is convenient for the installation or disassembly of the bending seat.

[0015] 2. The folding head on the folding device can be quickly snapped into the connection groove through the connecting block on it, and then the screw on the connecting plate is screwed into the folding head to fix the folding head. Therefore, the folding head can also be disassembled, enabling the device to replace the folding component according to the needs of plate folding, improving the practicability of the device.
