Description

Technical Field

[0001] This utility model belongs to the field of metallurgical machinery technology and relates to the flipping process of the pickling process of hot-rolled stainless steel medium and thick plates, specifically a fully hydraulic wide and thick plate flipping machine. Background Technology

[0002] In the pickling process of a medium-thick steel plate production line, a flipping machine is required to flip the medium-thick steel plates. There are two traditional types of flipping machines. One type has a single-sided flipping arm with a transport roller conveyor and an "L" shape. When the steel plate moves to the flipping area, the flipping arm rotates the steel plate 95°, and the steel plate becomes vertical, located on the vertical transport track. The impact of the steel plate on the vertical transport roller conveyor is relatively large, resulting in a high failure rate. The other type uses a "U"-shaped flipping arm. This structure ensures that when the steel plate is flipped to a vertical position, the impact is on the relatively robust flipping arm body rather than the vertical transport roller conveyor. However, the flipping arm can only return to a horizontal position and flip the next steel plate after the steel plate leaves the flipping area. This not only has low flipping efficiency but also causes scratches on the surface of the steel plate. Moreover, due to the different thicknesses of the steel plates, the position of the steel plate after flipping is uncertain. Utility Model Content

[0003] The purpose of this utility model is to provide a fully hydraulic thick plate flipping machine with a simple structure, which can be effectively applied to flipping steel plates of various thicknesses, and has a fast flipping efficiency. It can also effectively prevent scratches on the surface of medium and thick steel plates during the flipping process.

[0004] The technical solution adopted by this utility model to achieve the above objectives is as follows: A fully hydraulic wide and thick plate flipping machine includes a flipping mechanism and a receiving mechanism. The flipping mechanism is installed on a foundation steel structure fixed to the civil engineering foundation by anchor bolts, and the receiving mechanism is installed next to the flipping mechanism on a receiving steel structure fixed to the civil engineering foundation by anchor bolts.

[0005] Furthermore, the flipping mechanism includes a flipping platform, a main shaft, and a movable bumper. The flipping platform and the main shaft are connected by a key and reinforced by welding. The main shaft is hinged to the foundation steel structure. The flipping platform is composed of multiple equally spaced flipping arms. A main hydraulic cylinder is installed at the bottom of the flipping platform. The piston rod of the main hydraulic cylinder is hinged to the bottom of the flipping arm. The cylinder body hinge shaft of the main hydraulic cylinder is connected to the cylinder base. One end of the movable bumper is rotatably connected to the flipping platform through the bumper base. The end of the movable bumper away from the bumper base is connected to the bumper hydraulic cylinder through the bumper connecting rod.

[0006] Furthermore, the plate-receiving mechanism includes a plate, a plate-receiving connecting rod, and a plate-receiving hydraulic cylinder. One end of the plate is connected to the base steel structure of the flipping machine via a hinge, and the end of the plate away from the base steel structure is connected to the plate-receiving connecting rod. The plate-receiving connecting rod is connected to the plate-receiving hydraulic cylinder, which is fixed on the plate-receiving steel structure. The plate-receiving hydraulic cylinder drives the plate-receiving connecting rod to rotate the plate.

[0007] Furthermore, a movable pusher is also provided inside the tilting arm, which can extend out of the tilting arm. The movable pusher is driven by a pusher hydraulic cylinder fixed inside the tilting arm.

[0008] Furthermore, multiple nylon rollers are installed on the tilting arm.

[0009] The beneficial effects of this utility model are: This utility model has a simple structure and adopts a fully hydraulic drive. Through the coordinated action of each hydraulic cylinder, the steel plate flipping is mechanized. At the same time, the entire flipping process will not cause scratches on the surface of the steel plate. Attached Figure Description

[0012] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0013] like Figure 1 and Figure 2As shown, a fully hydraulic wide and thick plate flipping machine includes a flipping mechanism and a receiving mechanism. The flipping mechanism is installed on the foundation steel structure 2, which is fixed to the civil foundation 1 by anchor bolts. The receiving mechanism is installed next to the flipping mechanism and on the receiving steel structure 3, which is fixed to the civil foundation 1 by anchor bolts.

[0014] The flipping mechanism includes a flipping platform 4, a main shaft 5, and a movable bumper 6. The flipping platform 4 and the main shaft 5 are connected by a key and reinforced by welding. The main shaft 5 is hinged to the foundation steel structure 2. The flipping platform 4 is composed of multiple equally spaced flipping arms 41. A main hydraulic cylinder 7 is installed at the lower part of the flipping platform 4. The piston rod 71 of the main hydraulic cylinder 7 is hinged to the lower part of the flipping arm 41. The cylinder body hinge shaft 72 of the main hydraulic cylinder 7 is connected to the cylinder base 8. The movable bumper 6 is used for the steel plate to be placed against the edge. One end of the movable bumper 6 is rotatably connected to the flipping platform 4 through the bumper base 61. The end of the movable bumper 6 away from the bumper base 61 is connected to the bumper hydraulic cylinder 63 through the bumper connecting rod 62.

[0015] Multiple nylon rollers 42 are installed on the tilting arm 41 to prevent scratching the surface of the steel plate during the tilting process. The tilting arm 41 is also equipped with a movable push head 43 that can extend out of the tilting arm 41. The movable push head 43 is driven by a push head hydraulic cylinder 44 fixed inside the tilting arm 4.

[0016] The connecting plate mechanism includes a connecting plate 9, a connecting plate connecting rod 10, and a connecting plate hydraulic cylinder 11. One end of the connecting plate 9 is connected to the base steel structure 2 of the flipping plate mechanism by a hinge. The end of the connecting plate 9 away from the base steel structure 2 is connected to the connecting plate connecting rod 10. The connecting plate connecting rod 10 is connected to the connecting plate hydraulic cylinder 11. The connecting plate hydraulic cylinder 11 is fixed on the connecting plate steel structure 3. The connecting plate hydraulic cylinder 11 drives the connecting plate connecting rod 10 to drive the connecting plate 9 to rotate.

[0017] Work process: S1, Initial state; like Figure 3 As shown, the steel plate 12 moves to the flip plate working area. At this time, the flipping arm 41 of the flip plate frame 4 is in a low position, the movable bumper 6 is in a high position, and the receiving plate 9 of the receiving plate mechanism is in the initial position. S2, Flipping process; like Figure 4 As shown, the main hydraulic cylinder 7 drives the piston rod 71 to push the flipping arm 41 of the flipping platform 4 to flip. The stroke and synchronization of the main hydraulic cylinder 7 are controlled by the built-in displacement sensor. When the flipping arm 41 reaches the set angle, the plate receiving hydraulic cylinder 11 of the plate receiving mechanism drives the plate receiving rod 10 to rotate the plate receiving 9, so that the plate receiving 9 is in the plate receiving position. S3, Connecting process; like Figure 5As shown, after the connecting plate 9 is in the connecting plate position, the main hydraulic cylinder 7 extends through the piston rod 71 to drive the tilting arm 41 to rotate to the limit position, and the connecting plate hydraulic cylinder 11 drives the connecting plate connecting rod 10 to drive the connecting plate 9 to retract, completing the tilting; at the same time, the bumper hydraulic cylinder 63 drives the bumper connecting rod 62 to drive the movable bumper 6 to rotate to the retracted position. S4, Steel plate fine-tuning process; like Figure 6 As shown, the hydraulic cylinder 44 drives the movable pusher 43 to push the steel plate 12 from the tilting arm 41 to the receiving plate 9, and push the steel plate 12 to the final position. S5, Tilting arm recovery process; like Figure 7 As shown, the main hydraulic cylinder 7 drives the piston rod 71 to retract the tilting arm 41 to the lowest position, and the bumper hydraulic cylinder 63 drives the bumper connecting rod 62 to return the movable bumper 6 to the highest position, thus completing the entire tilting operation.
