Description

Technical Field

[0001] The utility model relates to the technical field of waste treatment devices, in particular to an aluminum alloy waste flattening device. Background Technique

[0002] During the production process of aluminum alloy coils, some coiled waste materials (referred to as coiled waste) are usually generated. For example, during the cold rolling process, due to the fact that equipment parameters such as the rolling speed have not reached the stable setting state, key indicators such as the thickness of the head and tail parts of the coil are different from those of the stable rolling part in the middle and need to be cut off. Or when the coil is being cleaned or the shape is corrected, the quality of the head and tail parts during the equipment debugging process does not meet the standards or there are quality defects and need to be cut off. These coiled waste materials will have an adverse impact on subsequent digestion and use.

[0003] In aluminum alloy production enterprises with a melting and casting workshop, generally, the aluminum alloy waste generated in each process will be classified and returned to the melting for use, and each alloy waste will be remelted as needed, so as to achieve the purpose of reducing production costs. The coiled waste generated during the production process of aluminum alloy coils has a large volume, light weight, and a large volume-mass ratio, which not only affects the transportation efficiency, but more importantly, will affect the feeding weight during the re-melting process, affect the stock preparation and melting efficiency, and increase the melting energy consumption.

[0004] To deal with the adverse effects caused by coiled waste materials, the traditional common solution is to purchase a hydraulic flattening device for treatment. However, this method not only requires purchasing expensive equipment, but also has a large energy consumption for flattening relatively thick coiled waste. Moreover, the hydraulic flattening device has many processing operation steps and low efficiency. At the same time, due to the relatively flat bottom of the force application structure, there is also a situation where the coiled waste is likely to pop out and hurt people when pressing down. Of course, there are also simple methods, such as using the forklift front fork plate to flatten, but this method can only handle relatively thin coiled waste, usually requires pressing down multiple times with low processing efficiency, and is easy to damage the forklift, there is a hidden danger of causing vehicle failures, and at the same time, the coiled waste is easy to pop out and is easy to hurt people. Content of the Utility Model

[0005] Aiming at the above deficiencies, the utility model provides an aluminum alloy waste flattening device, which can solve the problems of cumbersome operation, low efficiency, and easy to pop out and hurt people in the existing flattening operation of coiled waste.

[0006] To achieve the above object, the utility model adopts the following technical scheme: an aluminum alloy waste flattening device, comprising:

[0007] A flattening frame, in the middle of which a gravity plate is arranged, a bottom plate is fixedly arranged below the gravity plate, a receiving cavity is formed between the bottom plate and the gravity plate, and the bottom plate is provided with a plurality of through holes;

[0008] Flattened columns, the number of which is the same as the number of the through holes, and are correspondingly and respectively inserted through the through holes in a matching manner. A flange with a size larger than the through hole is provided at the top of the flattened column so that the body of the flattened column can pass through the through hole while the flange cannot pass through the through hole.

[0009] Furthermore, the distance between the bottom surface of the flattened column and the flange is equal to the distance between the bottom surface of the gravity plate and the bottom plate.

[0010] Furthermore, the flattened columns are evenly distributed on the bottom plate.

[0011] Furthermore, a plurality of connecting columns are evenly arranged at the edge of the gravity plate. The bottom of the connecting column is fixedly connected to the bottom plate. A side plate is detachably arranged between the connecting columns to enclose the accommodating cavity through the side plate and the connecting column.

[0012] Furthermore, the top of the connecting column extends upward higher than the gravity plate, and a lifting ring is arranged at the top of each connecting column.

[0013] Furthermore, a hanging rod is arranged upward in the middle of the gravity plate, and a lifting ring is arranged at the top of the hanging rod.

[0014] Furthermore, a connecting rod is arranged between the hanging rod and the connecting column.

[0015] Furthermore, a counterweight block is placed on the top surface of the gravity plate.

[0016] Furthermore, vertical rods are evenly arranged on the top surface of the gravity plate. An insertion hole is formed in the middle of the counterweight block, and the counterweight block is sleeved into the vertical rod through the insertion hole in a matching manner.

[0017] Furthermore, the insertion hole is a special-shaped hole so that the counterweight block cannot rotate when the counterweight block is sleeved into the vertical rod;

[0018] A lifting ear is arranged at the top of the counterweight block, and a placing cavity is arranged at the bottom of the counterweight block so that when two or more counterweight blocks are sleeved into one vertical rod, the lifting ear of the counterweight block located below is located in the placing cavity of the counterweight block located above.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: When using the aluminum alloy waste flattening device of the present utility model to perform the flattening operation on the coiled waste, the self-weight of the flattening frame and the flattened columns is utilized to flatten the coiled waste.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] Please refer to Figures 1 to 5 , a preferred embodiment of the present utility model provides an aluminum alloy waste flattening device, which mainly includes a flattening frame 10 and flattening columns 20. The flattening frame 10 and the flattening columns 20 have a certain weight to flatten the coiled waste through their own weights.

[0031] A gravity plate 14 is arranged in the middle of the flattening frame 10. A bottom plate 11 is fixedly arranged below the gravity plate 14. Both the bottom plate 11 and the gravity plate 14 are straight plate-like structures, and the gravity plate 14 is relatively thick and has a certain large weight. An accommodating cavity 12 is formed between the bottom plate 11 and the gravity plate 14, and the accommodating cavity 12 can accommodate the flattening columns 20. The bottom plate 11 is provided with a plurality of through holes 13. The through holes are round holes. The bottom plate 11 has a certain thickness so that the through holes 13 have a certain depth. When the flattening columns 20 are inserted into the through holes 13, the flattening columns 20 can only move up and down and will not swing sideways.

[0032] There are a plurality of flattening columns 20, and the number thereof is the same as that of the through holes 13 and they are correspondingly inserted into the through holes 13 one by one. At this time, the flattening columns 20 can move up and down in the through holes 13. A flange 21 with a size larger than the through holes 13 is arranged at the top of the flattening columns 20 so that the main body of the flattening columns 20 can pass through the through holes 13 while the flange 21 cannot pass through the through holes 13. At this time, when the flattening frame 10 is lifted, the flattening columns 20 naturally fall under their own action and are hung on the bottom plate 11 and extend downward from the bottom plate 11 under the limiting action of the flange 21.

[0033] The flattening frame 10 is vertically lifted or lowered through a hoisting device. For example, in a preferred embodiment, the aluminum alloy waste flattening device of the present utility model can be configured with a crane (not shown in the figure), and the flattening frame 10 is lifted or lowered through the crane. Of course, the coiled material needs to be hoisted by the crane when it is loaded onto and unloaded from the machine, and production enterprises are equipped with it, so there is no need to purchase and install it additionally and it can be directly used.

[0034] During implementation, the flattening frame 10 is lifted by a crane to a certain height. At this time, the coiled waste is placed directly below the flattening frame 10, and the flattening frame 10 is slowly lowered. When the flattening frame 10 descends, first, the flattening columns 20 come into contact with the coiled waste first. Since the coiled waste is irregular and the multiple flattening columns 20 cover the coiled waste in the vertical projection, therefore, the flattening column 20 that first contacts the coiled waste can only slightly press down the coiled waste due to insufficient weight and will be lifted by the coiled waste itself and gradually enter the accommodating cavity 12. And the other flattening columns 20 that have not contacted the coiled waste continue to descend until they contact the coiled waste (when there is coiled waste below the flattening column 20) and press down the coiled waste and are pushed into the accommodating cavity 12 by the coiled waste. The flattening frame 10 continues to descend until it contacts the ground or platform where the coiled waste is placed. At this time, the gravity plate 14 of the flattening frame 10 contacts the convex edge 21 of the flattening column 20, so that the weight of the flattening frame 10 is transmitted to the coiled waste through the flattening column 20, so as to realize the flattening of the coiled waste by the own weights of the flattening frame 10 and the flattening column 20. Since the flattening columns 20 that contact the coiled waste later can surround the coiled waste from the side, the multiple flattening columns 20 surrounding the coiled waste can limit the coiled waste, thereby effectively preventing the coiled waste from popping out and ensuring operation safety. Using the aluminum alloy waste flattening device of the present utility model to perform the flattening operation on the coiled waste, the own weights of the flattening frame 10 and the flattening column 20 are used to flatten the coiled waste. The operation is simple and efficient, can effectively flatten the coiled waste, and can avoid the coiled waste from popping out and hurting people to ensure production safety.

[0035] Furthermore, the distance between the bottom surface of the flattening column 20 and the convex edge 21 is equal to the distance between the bottom surface of the gravity plate 14 and the bottom plate 11. At this time, when the aluminum alloy waste flattening device of the present utility model is used to flatten the coiled waste, the flattening frame 10 continues to descend. Finally, when the bottom surface of the bottom plate 11 contacts the ground or platform where the coiled waste is placed, the bottom surface of the flattening column 20 just retracts into the through hole 13 and its bottom surface is flush with the bottom surface of the bottom plate 11, and the bottom surface of the gravity plate 14 just abuts against the top surface of the convex edge 21 of the flattening column 20. At this time, the weight of the entire gravity plate 14 and the components thereon is transmitted to the flattening column 20, and the flush bottom surfaces of the flattening column 20 and the bottom plate 11 can better flatten the coiled waste.

[0036] In this exemplary embodiment, the flattening columns 20 are evenly distributed on the bottom plate 11, and the flattening columns 20 are as close as possible to be densely arranged on the bottom plate 11. At this time, there are more flattening columns 20 and the coverage area is large enough, and the coiled waste can be flattened over a large area and evenly by the flattening columns 20.

[0037] In this exemplary embodiment, the gravity plate 14 is a square plate-like structure. A plurality of connecting columns 15 are uniformly arranged at the edge of the gravity plate 14. The connecting columns 15 are located at the four corners of the gravity plate 14. The bottom plate 11 is also a square plate-like structure, and its shape and vertical projection size are the same as those of the gravity plate 14. The bottom of the connecting column 15 is fixedly connected to the bottom plate 11, and the connection positions are at the four corners. At this time, an accommodation cavity 12 is formed at the middle position between the connecting column 15 and the bottom plate 11. Side plates 16 are detachably arranged between the connecting columns 15, and the detachable connection method is bolt connection, so as to enclose the accommodation cavity 12 through the side plates 16 and the connecting columns 15. By arranging the side plates 16, the accommodation cavity 12 can be temporarily formed into a closed structure to prevent external sundries from entering and affecting the movement of the flattening column 20 and the like.

[0038] The top of the connecting column 15 extends upward beyond the gravity plate 14. A lifting ring 17 is arranged at the top of each connecting column 15. By arranging the lifting ring 17, the connection with the overhead crane can be realized at the four corners. When the overhead crane lifts the flattening frame 10, it is respectively connected to the lifting rings 17 located at the four corners, so as to ensure the up-and-down stability of the flattening frame 10 and prevent the flattening frame 10 from shaking or tilting too much and affecting the flattening. A suspension rod 18 is arranged upward in the middle of the gravity plate 14, and a lifting ring 17 is arranged at the top of the suspension rod 18. At this time, the connection with the overhead crane is realized through the lifting ring 17 at the top of the suspension rod 18, strengthening the connection strength and effectively preventing the flattening frame 10 from shaking or tilting too much and affecting the flattening. A connecting rod 19 is arranged between the suspension rod 18 and the connecting column 15. At this time, the suspension rod 18 and the connecting column 15 are connected through the connecting rod 19, strengthening the strength of the suspension rod 18 and the connecting column 15, and preventing the suspension rod 18 or the connecting column 15 from being bent due to uneven force when shaking or tilting.

[0039] Considering that the thickness of the coiled waste is different, the required flattening weight is also different. Thinner coiled waste requires less flattening weight, while thicker coiled waste requires more flattening weight. If the flattening frame 10 and the flattening column 20 with a large weight are always used, an overhead crane with a large lifting force is required to lift and lower the flattening frame 10 and the flattening column 20. Then, when flattening thinner coiled waste, too much power is wasted; if the flattening frame 10 and the flattening column 20 with a small weight are always used, the flattening frame 10 and the flattening column 20 can be lifted and lowered by an overhead crane with a small lifting force to save power, but thicker coiled waste cannot be flattened well. At this time, by arranging the counterweight 30, the total weight of the flattening frame 10 and the flattening column 20 is adjusted to adapt to the flattening of different coiled wastes. Counterweights 30 are placed on the top surface of the gravity plate 14. The counterweights 30 can be multiple and can also be removed. When flattening thinner coiled waste, some or all of the counterweights 30 can be removed. When flattening thicker coiled waste, a certain amount of counterweights 30 can be placed to ensure the flattening of the coiled waste without wasting too much power of the overhead crane.

[0040] Vertical poles 110 are evenly arranged on the top surface of the gravity plate 14, and an insertion hole 31 is opened in the middle of the counterweight block 30. The counterweight block 30 is matched and inserted into the vertical pole 110 through the insertion hole 31. At this time, the counterweight block 30 will not move on the vertical pole 110, ensuring that the counterweight block 30 is placed in a certain position, and it is not easy to cause the center of gravity of the flattening frame 10 to shift to the edge and cause tilt. Preferably, the number of counterweight blocks 30 on each vertical pole 110 is the same. The insertion hole 31 is a special-shaped hole so that the counterweight block 30 cannot rotate when it is inserted into the vertical pole 110; the top of the counterweight block 30 is provided with a lifting ear 32, which is convenient for the staff to lift or put down the counterweight block 30. When lifting or putting down the counterweight block 30, a rope or the like is passed through the lifting ear 32, and the lifting ear 32 is located at a symmetrical position on both sides. A placement cavity 33 is provided at the bottom of the counterweight block 30 so that when two or more counterweight blocks 30 are inserted into a vertical pole 110, the lifting ear 32 of the counterweight block 30 at the bottom is located in the placement cavity 33 of the counterweight block 30 at the top. At this time, the counterweight blocks 30 can be stacked on each other and the stacking is stable and does not shake.

[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
