When the stamping machine works, the rotary driving mechanism drives the driving shaft 5 to rotate, the pinion 5a on the driving shaft 5 rotates to drive the big gears 4 to rotate, the big gears 4 are meshed with each other, the crankshafts 3 rotate simultaneously, the crankshafts 3 drive the connecting rods to swing, the connecting rods drive the sliding blocks to move up and down, and the upper dies on the sliding blocks are matched with the lower dies 2 of the machine body 1 to complete stamping; when the piston 13a pressing part 13a1 of the annular cylinder 13 presses the friction plate 16 of the second friction disc body 20, the friction plate 16 on the other side of the second friction disc body 20 is tightly attached to the joint disc 12, the flywheel 8 and the second friction disc body 20 rotate simultaneously, the first friction disc body 15 is spaced from the piston 13a, and the first friction disc body 15 is hung on the fixed rod 19 through the first connecting plate 17, and is in a clutch state; the piston 13a pressing part 13a1 of the annular cylinder 13 presses the friction plate 16 of the first friction disc 15, the friction plate 16 on the other side of the first friction disc 15 is attached to the brake disc 14, the piston 13a is separated from the friction plate 16 of the second friction disc 20, the first connecting plate 17 of the first friction disc 15 is fixed to the machine body 1 through the fixing rod 19, the brake disc 14 performs braking, and the driving shaft 5 performs braking, and at the moment, the braking state is achieved. The invention indirectly obtains the abrasion loss of the friction plate 16 by indirectly measuring the axial displacement of the first connecting plate 17 fixedly connected with the first friction plate body 15 and the axial displacement of the arc-shaped detection strip 28 fixedly connected with the second friction plate body 20. The invention has the advantages that: and a temperature sensor 6 and a displacement sensor 7 on the detection tool monitor the abrasion loss and the temperature of the clutch brake mechanism. The invention can monitor the clutch brake mechanism of the press machine and realize the intelligent detection and control of the clutch brake mechanism during working.
