Description

Technical Field

[0001] The utility model relates to the technical field of coil production, in particular to a plate turning and blanking device used for a hot-rolled high-strength coil production line. Background Art

[0002] Coil (hot rolled coil) is made from slab (mainly continuous casting slab) as raw material, which is heated and made into strip steel by rough rolling unit and finishing rolling unit. The hot steel strip coming out of the last rolling mill of the finishing rolling is cooled to the set temperature by laminar flow and rolled into a steel strip coil by a plate rolling machine. The cooled steel strip coil is processed into steel plates, flat coils and longitudinally cut steel strip products through different finishing lines (flattening, straightening, cross-cutting or longitudinal cutting, inspection, weighing, packaging and marking, etc.) according to different needs of users. Since hot-rolled steel plate products have high strength, good toughness, easy processing and forming, and good weldability, the coils are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels. However, in the current hot-rolled high-strength coil opening and longitudinal shearing combined production line, the finished plates are generally stacked by clamping and throwing during the processing of the coils. In this way, when the finished plates fall freely, they need to be pushed again, which will cause more scratches on the plate surface, and the stacking neatness is not good, affecting the subsequent packaging effect. Therefore, we propose a plate flipping and blanking device for a hot-rolled high-strength coil production line to solve the above problems. Utility Model Content

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment

[0024] As Figure 1 , Figure 2 and Figure 5As shown in the figure, a turning plate blanking device for a hot-rolled high-strength coil plate production line proposed by an embodiment of the present utility model includes a bottom plate 1. On the top of the bottom plate 1, a first roller path body 2 and a second roller path body 3 are fixed. Four support rods 4 are fixed on the top of the bottom plate 1. On the top of the four support rods 4, a support plate 5 is fixed. At the bottom of the support plate 5, a U-shaped seat 6 is fixed. Four sets of pull-out blanking mechanisms 7 are arranged on the U-shaped seat 6. At one end of the U-shaped seat 6, two side baffles 8 are fixed. At the other end of the U-shaped seat 6, a rear baffle 9 is fixed. A lifting frame mechanism 10 is arranged on the top of the bottom plate 1. When using this turning plate blanking device for the hot-rolled high-strength coil plate production line, after installing it in a suitable position, the flat and cut finished coil plate can be conveyed through the first roller path body 2. With the cooperation of the side baffles 8 and the rear baffle 9, at this time, the finished coil plate will be conveyed onto the four sets of pull-out blanking mechanisms 7 inside the U-shaped seat 6. Then, the lifting frame mechanism 10 can be started to move up into the U-shaped seat 6. At this time, the finished coil plate located inside the U-shaped seat 6 will be limited inside the lifting frame mechanism 10. Then, operate the four sets of pull-out blanking mechanisms 7 to release the support for the finished coil plate. Finally, under the limitation of the lifting frame mechanism 10, the plate can fall onto the second roller path body 3. Then, after resetting the lifting frame mechanism 10, the conveying can continue. Repeating this way, the finished coil plates can be neatly stacked on the second roller path body 3 without scratching the plate surface. When the finished coil plates are stacked to a certain number, continue to move the lifting frame mechanism 10 down. Finally, the second roller path body 3 can convey them to a suitable position for packaging.

[0025] As Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the pulling and blanking mechanism 7 includes a frame 701 fixed to one side wall of the U-shaped seat 6. A cylinder 702 is fixed to one inner wall of the frame 701. A pulling plate 703 is fixed to the ejecting end of the cylinder 702. Limiting grooves 706 are formed in both inner walls of the frame 701. Limiting blocks 707 adapted to the limiting grooves 706 are fixed to both side walls of the pulling plate 703, which can play a role in limiting and supporting the pulling plate 703, so as to make it more stable during sliding. One side of the pulling plate 703 slides through the U-shaped seat 6 and extends into its interior. Five guide pulleys 704 are rotatably connected to one side wall of the pulling plate 703 through bearings. Rubber protection rings 708 are fixed to the surfaces of the guide pulleys 704, which can play a role in protecting the conveyed metal plates and prevent the guide pulleys 704 from damaging the surface of the metal plates during blanking. Two reinforcing bars 705 are fixed to the top of the frame 701, and the other ends of the reinforcing bars 705 are fixedly connected to the U-shaped seat 6. During use, after the finished rolled plate moves into the interior of the U-shaped seat 6, it will be located on the guide pulleys 704. When the ejecting end of the cylinder 702 contracts, it drives the pulling plate 703 to move. After the pulling plate 703 moves, it drives the guide pulleys 704 to move. When the guide pulleys 704 move outward, the support for the finished rolled plate can be released, and then blanking of the finished rolled plate can be achieved. After blanking is completed, the pulling plate 703 can be reset into the interior of the U-shaped seat 6 again, so as to continue to support and blank the conveyed finished rolled plates. The provided reinforcing bars 705 can play a role in auxiliary support for the frame 701, so as to make it more stable after installation.

[0026] As Figure 1 and Figure 4As shown, in some embodiments, the lifting frame mechanism 10 includes two hydraulic cylinders 1001 fixed to the top of the bottom plate 1. A moving plate 1002 is fixed to the ejecting ends of the two hydraulic cylinders 1001. Four L-shaped auxiliary plates 1005 adapted to the moving plate 1002 are fixed to the top of the bottom plate 1. The top ends of the L-shaped auxiliary plates 1005 are fixedly connected to the bottom of the second roller path body 3, which can play a role in guiding and supporting the moving plate 1002, so that it will be more stable when moving up and down. Two first vertical plates 1003 and eight second vertical plates 1004 are fixed to the top of the moving plate 1002. The tops of the first vertical plates 1003 and the second vertical plates 1004 slide through the second roller path body 3 and extend above it. During use, the ejecting ends of the two hydraulic cylinders 1001 are started to push the moving plate 1002 upward. After the moving plate 1002 moves upward, it will drive the first vertical plates 1003 and the second vertical plates 1004 to move upward. At this time, the tops of the first vertical plates 1003 and the second vertical plates 1004 will move upward to a state where they are about to fit with the top of the U-shaped seat 6. At this time, the finished product can be limited between the first vertical plates 1003 and the second vertical plates 1004, so as to facilitate the blanking operation of the finished product coil plate. When the finished product coil plate is conveyed into the U-shaped seat 6 again, it is only necessary to move the first vertical plates 1003 and the second vertical plates 1004 downward to a height that does not affect the conveyance of the finished product coil plate into the U-shaped seat 6. Subsequently, when a certain number of stacked finished product coil plates are conveyed and packaged through the second roller path body 3, at this time, the first vertical plates 1003 and the second vertical plates 1004 can be moved downward to a position not higher than the contact surface of the conveying rollers of the second roller path body 3.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
