An extrusion sleeve 45 is provided on the lower part of the outer surface of the cam 44. The lower part of the outer surface of the cam 44 fits with the outer surface of the extrusion sleeve 45. The lower part of the outer surface of the extrusion sleeve 45 is fixedly connected with a punching rod 46. When the cam 44 rotates to make the extrusion sleeve 45 move upward, the compressed first spring 47 will release elastic potential energy to help the punching rod 46 quickly return to its initial position and prepare for the next punching action. The outer surface of the punching rod 46 is sleeved with a first spring 47. The upper and lower ends of the first spring 47 are fixedly connected to the lower part of the outer surface of the extrusion sleeve 45 and the top surface of the base 1. The outer surface of the punching rod 46 and the top surface of the base 1 are movably penetrated.

[0020] When the extrusion sleeve 45 moves downward under the push of the cam 44, the punching rod 46 will move downward synchronously. The outer surface of the punching rod 46 and the top surface of the base 1 are movably penetrated. The punching rod 46 can extend downward from the top surface of the base 1 to realize the punching action, causing the blank to undergo plastic deformation, and the blank can be effectively stamped and pre-formed.

[0021] The ejection device 3 includes a fixed box 301, the top surface of the fixed box 301 is fixedly connected to the bottom ends of the four support rods 2, the top surface of the fixed box 301 is fixedly connected to a placement block 302, the top surface of the fixed box 301 is movably penetrated by a push rod 304, the top surface of the placement block 302 is provided with a placement groove 303, the upper outer surface of the push rod 304 is movably penetrated by the bottom end of the placement block 302, the top end of the push rod 304 is fixedly connected to a top plate 305, the bottom end of the push rod 304 is fixedly connected to a support plate 306, the outer surface of the push rod 304 is sleeved with a second spring 307, the upper and lower ends of the second spring 307 are respectively fixedly connected to the lower inner wall of the fixed box 301 and the top surface of the support plate 306, the bottom surface of the support plate 306 is fixedly connected to two fixed plates 308, and the two fixed plates 308 are rotatably connected. The roller 309 and the lower inner wall of the fixed box 301 are fixedly connected to the limit plate 310, and the top surface of the limit plate 310 is slidably connected to the arc plate 311. When the arc plate 311 slides, it will push the roller 309 to roll upward, and the roller 309 rolls upward, driving the support plate 306 connected above it to move upward. The outer surface of the roller 309 fits into the inner wall of the arc plate 311, and the bottom surface of the arc plate 311 is fixedly connected to the slide plate 312. The top surface of the limit plate 310 is provided with a slide groove 313 for cooperating with the slide plate 312. One end of the arc plate 311 is fixedly connected to the pull rod 314, and one end of the pull rod 314 is movably penetrated through the side of the fixed box 301 and fixedly connected to the pull plate 315. Pull the pull plate 315, and the pull plate 315 drives the arc plate 311 to slide horizontally on the top surface of the limit plate 310 through the pull rod 314.

[0022] The roller 309 rolls upward, thereby driving the ejector rod 304 to move upward. When the ejector rod 304 moves upward, the top plate 305 at its top gradually extends into the placement groove 303 in the placement block 302, exerting an upward ejecting force on the preformed automobile bearing forging placed in the mold, ejecting the forging from the mold, and quickly taking out the stamped preformed blank.

[0023] Working principle: first place the automobile bearing forging blank in the placement groove 303, start the motor 43 and its output end drives the rotating shaft 42 to rotate, and the cam 44 installed on the outer surface of the rotating shaft 42 will rotate together with the rotating shaft 42. During the rotation of the cam 44, the lower part of the outer surface and the outer surface of the extrusion sleeve 45 are always kept in contact with each other. As the cam 44 rotates, different parts of its outer surface contact the extrusion sleeve 45, thereby pushing the extrusion sleeve 45 to move up and down. When the extrusion sleeve 45 moves downward under the push of the cam 44, the punching rod 46 will move downward synchronously. During the downward movement of the punching rod 46, the first spring 47 sleeved on its outer surface will be compressed. The upper and lower ends of the first spring 47 are fixedly connected to the lower outer surface of the extrusion sleeve 45 and the top surface of the base 1 respectively. When the cam 44 rotates to make the extrusion sleeve 45 move upward, the compressed first spring 47 releases elastic potential energy, helping the punching rod 46 to quickly return to its initial position and prepare for the next punching action. Since the outer surface of the punching rod 46 and the top surface of the base 1 are movably penetrated, the punching rod 46 can extend downward from the top surface of the base 1 to realize the punching action, causing the blank to undergo plastic deformation, thereby achieving the purpose of effectively punching and preforming the blank.

[0024] When it is necessary to eject the automobile bearing forging that has been pre-formed by stamping from the die, the operator pulls the pull plate 315, and the pull plate 315 drives the arc plate 311 to slide horizontally on the top surface of the limit plate 310 through the pull rod 314. When the arc plate 311 slides, it will push the roller 309 to roll upward. The upward rolling of the roller 309 drives the support plate 306 connected above it to move upward, and then drives the ejector rod 304 to move upward. When the ejector rod 304 moves upward, the top plate 305 at its top will gradually extend into the placement groove 303 in the placement block 302, applying an upward ejecting force to the pre-formed automobile bearing forging placed in the die, and ejecting the forging from the die, thereby achieving the purpose of quickly removing the stamped pre-formed blank.

[0025] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
