Description

Technical Field

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation in order to obtain a forging with certain mechanical properties, shape, and size.

[0003] For some wheel-shaped workpieces, forging equipment is required to press them into round billet shapes. Workers use fixtures to place cylindrical metal materials in round billet molds, and then use forging rams to flatten them into shape. Since the round billet is tightly fitted with the mold when forged, there will be material jams, which increases the ejection time. In order to make the discharge smoother, we propose an efficient ejection mechanism for forged workpieces, which can facilitate ejection to solve the above-mentioned deficiencies.

[0020] Hereinafter, embodiments of the forged workpiece efficient ejection mechanism of the present invention will be described with reference to the accompanying drawings.

The surface of the push rod 12 is sleeved with a spring 15, and the top and bottom ends of the spring 15 are fixedly connected to the slide cylinder 11 and the concave frame 13 respectively. A push plate 16 is slidably provided at the bottom of the inner surface of the mold frame 7. When the metal material of the mold frame 7 becomes a round blank and needs to be ejected, it only needs to drive the rotating rod 9 to rotate through the motor 8, and the rotation of the rotating rod 9 drives the cam 10 to rotate. By utilizing the design of its shape, when it rotates to the farthest position from the axis, the pulley 14 is lifted up, and the push rod 12 at the top of the concave frame 13 is driven to move through the sliding between the pulley 14, and the spring 15 is compressed. At the same time, the push rod 12 slides in the slide cylinder 11 and lifts the push plate 16, so that the push plate 16 slides in the mold frame 7, thereby ejecting the round blank in the mold frame 7. The worker only needs to use a manual clamp to clamp it out. By setting the above structure, the purpose of convenient ejection and avoiding jamming can be achieved.

[0023] In this embodiment, the initial position of the push rod 12 is located on the inner surface of the slide cylinder 11 , and the top end surface of the slide cylinder 11 is flush with the bottom surface of the inner cavity of the groove 20 , and the push rod 12 contacts the bottom of the top plate 16 when being ejected.

[0024] By setting the initial position of the push rod 12 to be located on the inner surface of the slide cylinder 11, and the top end surface of the slide cylinder 11 is flush with the bottom surface of the inner cavity of the groove 20, it is prevented that when the pressure head 5 applies pressure to the metal material, the bottom of the top plate 16 touches the slide cylinder 11, causing damage to the slide cylinder 11, thereby affecting the push rod 12 from sliding up and down in the slide cylinder 11.

[0025] In this embodiment: the bottom of the inner cavity of the mold frame 7 is annularly integrally formed with a convex edge, and the design of the convex edge can support the bottom edge of the metal material in the mold frame 7, and sliders 17 are fixedly connected to both sides of the surface of the top plate 16. The inner surface of the mold frame 7 forming the convex edge is provided with a sliding groove 18, and the surface of the slider 17 is slidably connected to the inner surface of the sliding groove 18.

[0026] By setting the surfaces on both sides of the top plate 16 to be fixedly connected with sliders 17, the inner surface of the convex edge of the mold frame 7 is provided with a sliding groove 18, and the surface of the slider 17 is slidably connected to the inner surface of the sliding groove 18, which plays a role of limiting and guiding the up and down movement of the top plate 16, and also supports the top plate 16.

[0027] Working principle: workers use manual clamps to place metal materials on the mold frame 7, and then use the mold frame 7 to transfer and place them in the groove 20 on the top of the support plate 2, and start the hydraulic cylinder 3. The hydraulic cylinder 3 drives the movable plate 4 to slide up and down on the surface of the sliding column 6, thereby moving the pressure head 5 at its bottom, and the pressure head 5 flattens the material in the mold frame 7 to make it into a round blank. When it needs to be ejected, start the motor 8, and the motor 8 drives the rotating rod 9 to rotate. The rotation of the rotating rod 9 drives the cam 10 to rotate. Using the design of its shape, when it rotates to the farthest position from the axis, the pulley 14 is lifted up, and the sliding between the pulley 14 drives the ejector rod 12 on the top of the concave frame 13 to move, and compress the spring 15. At the same time, the ejector rod 12 slides in the slide 11 and lifts the ejector plate 16, so that the ejector plate 16 slides in the mold frame 7, thereby ejecting the round blank in the mold frame 7. Workers only need to use manual clamps to clamp it out.

[0028] In summary, the efficient ejection mechanism for forging workpieces realizes convenient ejection and avoids the problem of material jamming through the arrangement of the die frame 7, the motor 8, the rotating rod 9, the cam 10, the slide 11, the ejector 12, the concave frame 13, the pulley 14, the spring 15 and the ejector plate 16.
