DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1-Figure 1 -4, the utility model discloses a bearing bending forming device, comprising a base 1, two columns 2 are arranged on the upper end of the base 1, a sliding groove 3 is opened on the upper end of the base 1, a clamping mold 4 is arranged inside the sliding groove 3, a driving mechanism 5 is arranged on one side of the base 1, a first turntable 6 and a second turntable 7 are rotatably installed on the opposite sides of the top ends of the two columns 2, a bevel gear 8 is fixedly arranged on the side of the first turntable 6 away from the second turntable 7, and a first turntable 6 is opened near the edge An arc groove 9, a mounting hole 10 is provided at a position of the second turntable 7 corresponding to one end of the arc groove 9, an axial handle 11 is provided inside the mounting hole 10, and one end of the axial handle 11 is inserted into the arc groove 9, a connecting rod 12 is rotatably connected to the outer surface of the axial handle 11, a pressure rod 13 is rotatably provided at the bottom end of the connecting rod 12, a cavity 14 is provided inside the pressure rod 13, a vibration mechanism 15 is provided inside the cavity 14, and a cylindrical pressure rod 16 is provided at the bottom end of the pressure rod 13.

[0026] In this embodiment, when in use, the driving mechanism 5 is used to drive the clamping die 4 and the first turntable 6 to rotate the first turntable 6. Since the shaft handle 11 is inserted into the arc groove 9, the shaft handle 11 and one end of the arc groove 9 are in contact with each other during the rotation of the first turntable 6, and the shaft handle 11 is driven to rotate around the first turntable 6. When the shaft handle 11 rotates to the upper end of the first turntable 6, the first shaft handle 11 moves downward along the arc surface of the arc groove 9 under the action of the gravity of the connecting rod 12, the pressure rod 13 and the cylindrical pressure rod 16, so that the cylindrical pressure rod 16 can be pressed on the top of the clamping die, thereby achieving the effect of bending the metal plate placed on the top of the clamping die 4.

[0027] After the cylindrical pressure rod 16 contacts the metal plate under the action of gravity, the vibration mechanism 15 located inside the cavity 14 will vibrate violently under the action of the spring, and then frequently apply pressure to the metal plate again, causing the metal plate to further deform and bend;

[0028] In the above process, the first turntable 6 is still rotating, and when the groove wall of the arc groove 9 contacts the shaft handle 11 again, pressure is applied to the shaft handle 11, so that the shaft handle 11 is pushed downward, thereby applying pressure to the cylindrical pressure rod 16 again, so as to achieve the purpose of bending the metal plate again;
