[0010] Figure 1 The utility model is a schematic structural diagram of a blank centering device for a ring forging press. DETAILED DESCRIPTION
[0011] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.
[0012] like Figure 1As shown, a blank centering device for a ring forging press comprises: two centering units respectively arranged on the left and right sides of the press 10, each centering unit comprising: a base 1, a lifting seat 2 and a lifting drive mechanism capable of driving the lifting seat 2 to move up and down are arranged on the base 1, in this embodiment, the lifting seat 2 is vertically guided by a vertical column arranged on the base, and the lifting drive mechanism is an oil cylinder arranged below the ground; a centering clamp 3 located on the inner side of the lifting seat 2 is arranged on the lifting seat 2, A first centering oil cylinder 4 that can drive the centering splint 3 to move left and right, two side swing arms 5 located on both sides of the centering splint 3, one end of the two side swing arms 5 are respectively hinged to the two ends of the centering splint 3, a guide column 6 is arranged between the centering splint 3 and the lifting seat 2, the guide column 6 is penetrated in the lifting seat 2, the centering splint 3 is fixed to one end of the guide column 6, the guide column 6 can guide the left and right movement of the centering splint 3 and can support the centering splint 3, two guide columns 6 are arranged, the first centering oil cylinder 4 is located between the two guide columns A second centering oil cylinder 7 and a connecting rod 8 are respectively arranged between the two side swing arms 5 and the lifting seat 2. The second centering oil cylinder 7 is fixed on the lifting seat 2. The top of the piston rod of the second centering oil cylinder 7 is hinged to one end of the connecting rod 8, and the other end of the connecting rod 8 is hinged to the back of the side swing arm 5. After the piston rods of the two second centering oil cylinders 7 are extended, they can drive the two side swing arms 5 to swing toward each other through their respective connecting rods 8; the stroke of the second centering oil cylinder 7 is greater than that of the first centering oil cylinder 4, and the two centering oil cylinders 7 are connected to the lifting seat 2.
