Description
Technical Field
[0001] The utility model relates to the field of flange forging, in particular to a hoisting and transferring device for forging a steel billet. Background Art
[0002] When forging existing flanges of larger sizes, the cylindrical steel billet is first forged into a disc shape by a forging hammer, and a center hole is forged at the center of the disc. The steel billet is then turned vertically to forge the side of the steel billet. During this process, the steel billet needs to be transferred to a special support for fixation. When the existing lifting and transfer structure is in use, generally a support column is used to pass through the center hole of the steel billet, and then the support column and the steel billet are transported together. During the transportation process, the steel billet raw material can easily move relative to the support column, resulting in certain safety hazards in the lifting process. When the steel billet is lifted onto the support for subsequent forging, the support column continues to vibrate as the forging proceeds, which can easily cause the steel billet to fall from the support column. There is also a risk of the flange steel billet, which is larger in size and weight, falling off. As a result, the safety of the entire forging process of the existing flange needs to be further improved. Utility Model Content

[0006] Furthermore, a groove is provided at the bottom of the lifting ear, and the return spring is arranged between the top of the groove and the bottom of the slide groove.
[0007] Furthermore, a rotating wheel is rotatably connected to the side of the support, the clamping member is fixed to the side of the rotating wheel, and a power component for driving the rotating wheel to rotate is provided on the support.
[0008] Furthermore, the longitudinal section of the clamping piece is fan-shaped, and one end of the clamping piece is provided with an anti-slip stripe, and the anti-slip stripe is in contact with the side surface of the support column.

[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The structure of the utility model is that slide grooves are symmetrically arranged on both sides of the support column, and a lifting ear is connected in the slide groove along the vertical sliding. The bottom of the lifting ear is provided with a limit block used in conjunction with the top of the slide groove, and a return spring is provided between the bottom of the lifting ear and the bottom of the slide groove. In this structure, before the hook is lifted, the lifting ear slides downward to the inside of the slide groove under the action of the return spring, so that the operator can use the operating rod to more easily insert the support column as a whole into the center hole of the flange steel billet. When the hook and the lifting ear are lifted in cooperation, the lifting ear slides relative to the slide groove under the action of gravity until the limit block at the bottom of the lifting ear contacts the top of the slide groove, so that the lifting ear obviously protrudes from the top of the support column, forming an effective limit on both sides of the flange steel billet sleeved on the support column, preventing the flange steel billet from falling from the support column, and improving the safety during transportation;

[0020] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0021] Reference Figure 1 and Figure 2The utility model is a lifting and transferring device for forging a steel billet. The main structure includes a support column 2, a hook 3, and a support 4 that penetrates the center hole of the flange steel billet 1. The support column 2 is a cylindrical structure made of metal material and is used to transport the flange steel billet 1 with the center hole and support it during subsequent forging. The support 4 is used to support the support column 2 on which the flange steel billet 1 is sleeved. During forging, the flange steel billet 1 on the support column 2 is continuously rotated to achieve forging and forming of the size of the side surface of the flange steel billet 1. The hook 3 can adopt any structure of the hook 3 on the existing market, and it is driven and moved by lifting equipment such as a crane. The two sides of the support column 2 are symmetrically provided with lifting ears 5 used in conjunction with the hook 3, and the lifting ears 5 are arranged At the position near the two ends of the top of the supporting column 2, the hook 3 hooks the ear holes of the lifting ear 5 for connection, and the two sides of the supporting column 2 are symmetrically provided with slide grooves 6, and the slide groove 6 is recessed downward from the top of the supporting column 2. The lifting ear 5 is vertically slidably connected in the slide groove 6, and a return spring 7 is provided between the bottom of the lifting ear 5 and the bottom of the slide groove 6. When not in use, the lifting ear 5 slides downward into the slide groove 6 under the action of the return spring 7, so that a part of the lifting ear 5 is hidden in the slide groove 6, so that the height of the lifting ear 5 does not protrude too much from the top of the supporting column 2, thereby reducing the vertical height of the supporting column 2, making it easier to penetrate it into the center hole of the flange billet 1, which is suitable for lifting flange billets 1 of more sizes. The bottom of the lifting ear 5 is provided with a limit block 8 used in conjunction with the top of the slide 6. Specifically, a limit step used in conjunction with the limit block 8 is provided on the top of the slide 6. When the hook 3 hooks the lifting ear 5 for transportation, the lifting ear 5 slides upward relative to the slide 6 under the action of gravity until the limit block 8 contacts the limit step. At this time, the lifting ears 5 on both sides obviously protrude from the top of the support column 2, forming an effective limit to the position of the flange steel billet 1 on both sides of the support column 2 during the lifting process, thereby avoiding the flange steel billet 1 from falling off during the lifting process and improving the safety of the lifting. The top of the support 4 is provided with a placement groove 9 used in conjunction with the support column 2. The support column 2 with the flange steel billet 1 is lifted into the placement groove 9 to achieve the support column 2 position is effectively restricted, a clamping piece 10 used in conjunction with the support column 2 is provided on the side of the support 4, and the clamping piece 10 can contact and clamp the support column 2 in the placement groove 9 to avoid the support column 2 from moving relative to the support 4 due to vibration during the forging process, so that the flange billet 1 on the support column 2 is more stable, ensuring the safety of the side forging of the flange billet 1, and an operating rod 11 is welded or integrally formed at one end of the support column 2. When the support column 2 penetrates the center hole of the flange billet 1 and when the support column 2 is pulled out, the operator uses the operating rod 11 to operate the support column 2, which improves the convenience of the support column 2 and the flange billet 1. The risk of scalding caused by high temperature is reduced.
[0022] Preferably, refer to Figure 4A groove 12 is provided at the bottom of the lifting ear 5, and the groove 12 is recessed inward from the top of the lifting ear 5. The reset spring 7 is arranged between the top of the groove 12 and the bottom of the slide groove 6. Such a structure allows the lifting ear 5 to completely slide downward until the bottom contacts the bottom of the slide groove 6, so that the reset spring 7 can be completely hidden in the groove 12, so that the lifting ear 5 can slide downward and hide over a larger distance, further reducing the protruding height of both sides of the support column 2 at the position of the lifting ear 5, and improving the adaptability of the support column 2 to the center hole of flange steel billets 1 of different sizes.
[0023] Preferably, refer to Figure 3 The side of the support 4 is rotatably connected to a rotating wheel 13 through a bearing, and the clamping piece 10 is welded or bolted to the side of the rotating wheel 13. The support 4 is provided with a power component for driving the rotating wheel 13 to rotate. After the support column 2 is placed in the placement groove 9, such a structure drives the transport to rotate through the power component, so that the clamping piece 10 on the transport rotates to contact the side of the support column 2, thereby clamping the support column 2 in the placement groove 9, avoiding the separation of the support column 2 and the support 4 during the forging process, and further ensuring the convenience and stability of the clamping and fixing of the support column 2.
[0024] Preferably, the longitudinal cross-section of the clamping member 10 is fan-shaped. The fan-shaped structure makes it difficult for the clamping member 10 to interfere with the movement of other components as the rotating wheel 13 rotates, so that the movement of the clamping member 10 is smoother. One end of the clamping member 10 is provided with an anti-slip stripe 14, and the anti-slip stripe 14 is in contact with the side of the support column 2. Such a structure utilizes the anti-slip stripe 14 to increase the friction between the contact surface of the clamping member 10 and the support column 2, thereby improving the effect of clamping and fixing the support column 2.
[0025] Preferably, the power assembly includes a motor 15 and a gear 16. The motor 15 is welded or bolted to the side of the support 4. The gears 16 are two meshingly connected. The two gears 16 are respectively welded or bolted to the output shaft of the motor 15 and the rotating wheel 13. Such a structure enables the motor 15 to successfully drive the transfer and clamping member 10 to rotate under the meshing connection of the two gears 16 when it rotates, making the rotation control of the clamping member 10 more convenient and efficient. At the same time, the self-locking function of the motor 15 is used to maintain the clamping state of the clamping member 10 on the support column 2, further improving the convenience of clamping control.
[0026] Preferably, the hook 3 is a scissor-type structure, such a structure makes the hook 3 fit more firmly with the ears 5 on both sides, and an insulation rod 17 is provided at the end of the operating rod 11. The insulation rod 17 is made of insulation materials such as glass fiber or polymer plastic and is formed on the outside of a steel column or a wooden handle, so that the operator is not easily burned by high temperature when holding the insulation rod 17 during operation, thereby ensuring the convenience and safety of operating the support column 2.
[0027] Working principle: The structure of the utility model is symmetrically provided with slide grooves 6 on both sides of the support column 2, and a lifting ear 5 is connected to the slide groove 6 along the vertical sliding direction. The bottom of the lifting ear 5 is provided with a limit block 8 used to cooperate with the top of the slide groove 6, and a return spring 7 is provided between the bottom of the lifting ear 5 and the bottom of the slide groove 6. In this structure, before the hook 3 is lifted, the lifting ear 5 slides downward to the inside of the slide groove 6 under the action of the return spring 7, so that the operator can use the operating rod 11 to more easily penetrate the support column 2 as a whole into the center hole of the flange steel billet 1. When the hook 3 cooperates with the lifting ear 5 for lifting, the lifting ear 5 slides relative to the slide groove 6 under the action of gravity until the limit block 8 at the bottom of the lifting ear 5 contacts the top of the slide groove 6, so that the lifting ear 5 obviously protrudes from the top of the support column 2, forming a contact with the support column 2. The effective limiters on both sides of the sleeve flange billet 1 prevent the flange billet 1 from falling from the support column 2, thereby improving the safety during transportation; the hook 3 transfers the support column 2 with the flange billet 1 to the placement groove 9 of the support 4, and at this time, the clamping piece 10 on the side of the support 4 is used to clamp and fix the support column 2 to ensure the stability of the relative position of the support column 2 and the support 4, so that there is no gap between the two, so that the flange billet 1 on the support column 2 is not easy to fall off the support column 2, thereby ensuring the stability of the position of the flange billet 1 during the forging process. After forging is completed, the support column 2 is pulled out of the center hole of the flange billet 1 using the operating rod 11, and the flange billet 1 can be lifted alone, so that the flange billet 1 after lifting is more secure, thereby ensuring the safety of the subsequent forging process.
