[0027] In one embodiment of the utility model, the inner bottom of the mounting frame 1 is fixedly connected with a support column 2, the top end surface of the support column 2 is fixedly connected with a placement plate 3, the top end surface of the placement plate 3 is fixedly connected with a mounting block 9, the top end surface of the placement plate 3 is provided with a through hole 4, the bottom end surface of the placement plate 3 is fixedly connected with a waste hopper 5, the cut part of the gear falls into the waste hopper 5 through the through hole 4, the side wall of the mounting block 9 is movably connected with a mounting column 10, one end of the mounting column 10 is fixedly connected with a connecting piece 11, the end of the connecting piece 11 away from the mounting column 10 is fixedly connected with a clamping arm 12, the inner wall of the clamping arm 12 is fixedly connected with a rubber bump, the rubber bump can increase the friction between the clamping arm 12 and the gear, the top end surface of the placement plate 3 is fixedly connected with a mounting plate 13, the side wall sleeve of the mounting column 10 is provided with a spring 14, one end of the spring 14 Abutting against the side wall of the mounting plate 13, the other end of the spring 14 is fixedly connected to the side wall of the mounting column 10, the mounting block 9 is movably connected to the abutting plate 16, an arc-shaped groove is provided at the bottom of the abutting plate 16, a rubber pad 17 is fixedly connected in the arc-shaped groove, an elastic member 15 is fixedly connected to the top end surface of the abutting plate 16, the top end surface of the elastic member 15 is fixedly connected to the top plate 18, the bottom end surface of the top plate 18 is fixedly connected to the elastic element 19, the bottom end surface of the elastic element 19 is fixedly connected to the placement plate 3, the side wall of the hydraulic rod 7 is fixedly connected to a limiting block 20, the diameter of the limiting block 20 is larger than the inner diameter of the opening provided on the top plate 18, the bottom end surface of the top plate 18 is fixedly connected to an ejector pin 21, the number of the ejector pins 21 is provided in several groups, and several groups of ejector pins 21 are circumferentially distributed on the bottom end surface of the top plate 18 with the axis of the top plate 18 as the rotation axis.

[0028] The gear is placed between the clamping arms 12, and the gear pushes the clamping arms 12 and the mounting plate 13 to deform, so that the clamping arms 12 can adapt to gears of different sizes. The rubber bumps arranged on the clamping arms 12 can increase the friction between the clamping arms 12 and the gear to prevent the gear from rotating. Since the clamping arms 12 are deformed, the positional relationship between the mounting plate 13 and the mounting column 10 will be changed. The spring 14 pushes the mounting column 10, the connecting piece 11 and the clamping arms 12 to tightly abut the gear. The hydraulic cylinder 6 pushes the hydraulic rod 7 to move downward, and further pushes the die 8 to move downward to punch the gear. When the hydraulic rod 7 moves downward, it pushes the limit block 20 and the top plate 18 to move downward, and further pushes the elastic member 15 and the abutment plate 16 to move downward, so that the abutment plate 16 is tightly abutted against the mounting column 10.

[0029] In addition, a pin 21 is fixedly connected to the bottom end surface of the top plate 18. The number of the pins 21 is arranged in several groups. The several groups of pins 21 are distributed in a circle on the bottom end surface of the top plate 18 with the axis of the top plate 18 as the rotation axis. The hydraulic rod 7 moves downward to push the limit block 20 to move downward, further pushing the top plate 18 to move downward, so that the pin 21 contacts the gear. The elastic element 19 causes the pin 21 to always contact the top end surface of the gear through elastic deformation, thereby preventing the gear from longitudinal displacement or rotation.

[0030] In the present invention, when in use, the gear is placed between the clamping arms 12, and the gear pushes the clamping arms 12 and the mounting plate 13 to deform, so that the clamping arms 12 can adapt to gears of different sizes. The rubber bumps arranged on the clamping arms 12 can increase the friction between the clamping arms 12 and the gear to prevent the gear from rotating. Since the clamping arms 12 are deformed, the positional relationship between the mounting plate 13 and the mounting column 10 will be changed. The spring 14 pushes the mounting column 10, the connecting piece 11 and the clamping arms 12 to tightly contact the gear, and the hydraulic cylinder 6 pushes the hydraulic rod 7 to move downward, further pushing the die 8 to move downward, so as to rotate the gear. Punching, when the hydraulic rod 7 moves downward, it pushes the limit block 20 and the top plate 18 to move downward, and further pushes the elastic member 15 and the abutment plate 16 to move downward, so that the abutment plate 16 is tightly abutted against the mounting column 10, and the rubber pad 17 can increase the friction between the abutment plate 16 and the mounting column 10 to prevent the mounting column 10 from being displaced during stamping. Further, the hydraulic rod 7 moves downward to push the limit block 20 to move downward, and further pushes the top plate 18 to move downward, so that the ejector pin 21 contacts the gear, and the elastic element 19 elastically deforms so that the ejector pin 21 is always abutted against the top end face of the gear to prevent the gear from being longitudinally displaced or rotated.

Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
