Description

Technical Field

[0001] This utility model belongs to the field of stainless steel product manufacturing, specifically relating to a flat steel ingot or steel slab turning device. Background Technology

[0002] Flat steel ingots or slabs refer to steel products with a width of 500-1300mm, a thickness of 100-300mm, a length of no more than 2000mm, and a rectangular cross-section with slightly blunt edges. Flat steel ingots can be finished steel products, or they can be used as billets for welded pipes and slabs for continuously rolled thin plates. They can be hot-forged into various forgings or hot-rolled into medium and heavy plates and hot-rolled strips, and are widely used in shipbuilding, pressure vessels, machinery and equipment, aerospace molds, cold-rolled precision strips, and other fields.

[0003] The production process of flat steel ingots involves pouring molten metal into a mold to cool and solidify. The resulting ingots contain oxides and residues. After hot forging, the surface of the ingots may exhibit defects such as folds, peeling, flaking, oxide scale, and cracks, requiring surface repair to remove these defects. Both sides of the flat steel ingot or slab need to be repaired. After one side is repaired, the ingot or slab needs to be flipped so that the other side faces upwards for easier repair. However, flat steel ingots or slabs are typically very heavy, and the current conventional method of flipping them involves a combination of manual labor and overhead cranes, which is time-consuming and labor-intensive. Furthermore, the large volume and weight of the flat steel ingot or slab during flipping can easily cause slippage and crush workers, resulting in injury. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the fact that the conventional method of turning flat steel ingots or steel slabs is to rely on the coordination of manual labor and cranes, which is time-consuming and labor-intensive. At the same time, if the large-volume and heavy flat steel ingots or steel slabs slip during the turning process, they are easy to crush the operators and cause certain degrees of personal injury to the operators.

[0005] To solve the above-mentioned technical problems, this utility model provides a flat steel ingot or steel slab turning device, including a workbench, a connecting frame, a first turning frame, a second turning frame, a first driving mechanism, and a second driving mechanism. The connecting frame is fixed to the top surface of the workbench. The first turning frame and the second turning frame are respectively arranged in the left and right halves of the connecting frame. The right side of the first turning frame is hinged to the left side of the center of the connecting frame, and the left side of the second turning frame is hinged to the right side of the center of the connecting frame. The first driving mechanism can drive the first turning frame to flip from a horizontal state to the right, and the second driving mechanism can drive the second turning frame to flip from a horizontal state to the left. The flat steel ingot or steel slab can be placed on the top surface of the first turning frame when it is in a horizontal state or on the top surface of the second turning frame when it is in a horizontal state.

[0006] Preferably, the workbench includes a tabletop and legs, with the tabletop fixed to the top of the legs.

[0007] Preferably, the first and second flippers are hinged to the platform.

[0008] Preferably, the first driving structure is a first hydraulic push rod, and the second driving structure is a second hydraulic push rod; the first hydraulic push rod includes a first oil cylinder and a first piston rod, the free end of the first oil cylinder is hinged to the bottom end of the left support leg, and the free end of the first piston rod is hinged to the first tilting frame; the second hydraulic push rod includes a second oil cylinder and a second piston rod, the free end of the second oil cylinder is hinged to the bottom end of the right support leg, and the free end of the second piston rod is hinged to the second tilting frame.

[0009] Preferably, the first tilting frame is provided with a first limiting protrusion on the right side, and the second tilting frame is provided with a second limiting protrusion on the left side.

[0010] The technical solution of this utility model has the following beneficial effects:

[0011] This utility model includes a workbench with a first flipping frame and a second flipping frame. The first and second flipping frames are respectively located on the left and right halves of the workbench. The right side of the first flipping frame is hinged to the left side of the center of the connecting frame, and the left side of the second flipping frame is hinged to the right side of the center of the connecting frame. The first driving mechanism can drive the first flipping frame to flip from a horizontal position to the right, and the second driving mechanism can drive the second flipping frame to flip from a horizontal position to the left. Flat steel ingots or steel slabs can be placed on the top surface of the first or second flipping frame when it is in a horizontal position. The driving mechanism can drive one of the flipping frames to flip towards the other, thereby flipping the flat steel ingots or steel slabs. This utility model improves the efficiency of flipping flat steel ingots or steel slabs and can prevent them from slipping during the flipping process, thus avoiding the safety hazard of flat steel ingots or steel slabs easily crushing and injuring people.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] This utility model provides a flat steel ingot or steel slab turning device, including a workbench 1, a connecting frame 2, a first turning frame 3, a second turning frame 4, a first driving mechanism, and a second driving mechanism. The connecting frame 2 is fixed on the top surface of the workbench 1. The first turning frame 3 and the second turning frame 4 are respectively arranged on the left and right halves of the workbench 11. The right side of the first turning frame 3 is hinged to the left side of the center of the connecting frame 2, and the left side of the second turning frame 4 is hinged to the right side of the center of the connecting frame 2. The first driving mechanism can drive the first turning frame 3 to flip from a horizontal state to the right, and the second driving mechanism can drive the second turning frame 4 to flip from a horizontal state to the left. The flat steel ingot 9 or steel slab 9 can be placed on the top surface of the first turning frame 3 when it is in a horizontal state or on the top surface of the second turning frame 4 when it is in a horizontal state.

[0020] The working principle of this utility model is as follows: When it is necessary to flip the flat steel ingot 9 or steel slab 9, the flipping rack on which the flat steel ingot 9 or steel slab 9 is placed is first flipped. For example, if the flat steel ingot 9 or steel slab 9 was originally placed flat on the top surface of the first flipping rack 3, and it is necessary to flip the flat steel ingot 9 or steel slab 9:

[0021] Step 1. First, use the first drive mechanism to slightly lift the first tilting frame 3, and then use the second drive mechanism to slightly lift the second tilting frame 4. The lifting speed of the second tilting frame 4 is faster than that of the connecting frame. Stop tilting when the second tilting frame 4 tilts to a 290-degree angle with the connecting frame. This serves two purposes: firstly, it can block and buffer premature tilting of the flat steel ingot 9 or steel slab 9; secondly, it can effectively ensure the stability of the transfer of the flat steel ingot 9 or steel slab 9, and greatly reduce the impact damage to the equipment caused by the flat steel ingot 9 or steel slab 9 falling from a long distance.

[0022] Step 2. After the second tilting frame 4 stops tilting, the first tilting frame 3 continues to tilt until it tilts to a 290-degree angle with the connecting frame and also stops tilting. At this time, the flat steel ingot 9 or steel plate billet 9 completes the transfer operation and is transferred from the first tilting frame 3 to the second tilting frame 4.

[0023] Step 3. The second flipping frame 4 descends slowly, while the first flipping frame 3 remains stationary. The first flipping frame 3 protects the flat steel ingot 9 or steel slab 9, preventing it from sliding to the left. When the flat steel ingot 9 or steel slab 9 is in a horizontal position, the first flipping frame 3 flips to the left to reset, thus completing the flipping of the flat steel ingot 9 or steel slab 9.

[0024] Specifically, the workbench 1 includes a table plate 11 and support legs 12. The table plate 11 is fixed to the top of the support legs 12. The first flipper 3 and the second flipper 4 are hinged to the table plate 11. The support legs 12 mainly serve to raise the table plate 11, so that the flat steel ingot 9 or steel billet 9 is raised to a suitable height position, which makes it convenient for workers to finish the surface of the flat steel ingot 9 or steel billet 9.

[0025] Specifically, the first driving structure is a first hydraulic push rod 5, and the second driving structure is a second hydraulic push rod 6. The first hydraulic push rod 5 includes a first oil cylinder and a first piston rod. The free end of the first oil cylinder is hinged to the bottom end of the left support leg 12, and the free end of the first piston rod is hinged to the first tilting frame 3. The second hydraulic push rod 6 includes a second oil cylinder and a second piston rod. The free end of the second oil cylinder 61 is hinged to the bottom end of the right support leg 12, and the free end of the second piston rod is hinged to the second tilting frame 4. When the first piston rod extends, the first tilting frame 3 can be lifted (or flipped). When the second piston rod extends, the second tilting frame 4 can be lifted (or flipped).

[0026] The first tilting frame 3 has a first limiting protrusion 7 on its right side, and the second tilting frame 4 has a second limiting protrusion 8 on its left side. If the flat steel ingot 9 or steel slab 9 was originally placed on the first flipping frame 3, when the first flipping frame 3 transfers the flat steel ingot 9 or steel slab 9 to the second flipping frame 4, the first limiting protrusion 7 can ensure that when the first flipping frame 3 flips from a horizontal state to a state 90° with the connecting frame 2, the flat steel ingot 9 or steel slab 9 is ultimately in a vertical state and will not tilt, thus avoiding failure of the transfer operation. If the flat steel ingot 9 or steel slab 9 was originally placed on the second flipping frame 4, when the second flipping frame 4 transfers the flat steel ingot 9 or steel slab 9 to the first flipping frame 3, the second limiting protrusion 8 can ensure that when the second flipping frame 4 flips from a horizontal state to a state 90° with the connecting frame 2, the flat steel ingot 9 or steel slab 9 is ultimately in a vertical state and will not tilt, thus avoiding failure of the transfer operation.

[0027] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
