[0005] The technical solution adopted by the utility model to solve its technical problems is: a press brake disc assembly, including a wheel hub, a flywheel is arranged on the outer side of the wheel hub, the flywheel is in contact with friction wheels on both sides, a plurality of groups of support frames are fixedly installed on the inner side of the wheel hub, a group of brake pads can be detachably installed on each group of the support frames, each group of the brake pads are spliced ​​and installed to form a circular ring, and a brake mechanism is arranged on the outer side of the brake pads.

[0006] Furthermore, a mounting plate is fixedly mounted on the inner side of each group of support frames, and a screw rod is fixedly mounted on the lower end of the mounting plate.

[0007] Furthermore, the support frame is provided with a plurality of groups of threaded holes, the brake pad is provided with through holes, the through holes and the threaded holes are arranged correspondingly, and the through holes and the threaded holes are fastened and installed by bolts.

[0008] Furthermore, the brake mechanism includes a gantry, which is fixedly mounted on the outside of the press housing, and two groups of cylinders are fixedly mounted on the lower end of the gantry. The telescopic ends of the cylinders are fixedly connected to friction plates, and the inner side of the friction plate contacts the side of the brake pad.

[0009] The beneficial effects of the utility model are as follows: multiple groups of brake pads can be detachably installed by bolts, so that each group of brake pads can be spliced ​​and installed to form a circular ring. When one group of brake pads is damaged, the corresponding brake pad can be replaced without disassembling the entire group, which is convenient for replacement. When braking, two groups of cylinders are started at the same time, so that the cylinders drive the friction plate to move inward, so that the friction plate and the side of the brake pad are in friction contact, and braking is achieved without causing damage to the side of the flywheel, thereby ensuring the normal operation of the flywheel.
