Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum alloy production, and in particular relates to a short-process aluminum alloy slab casting system. Background Art

[0002] In an aluminum alloy slab casting system, after casting, it is necessary to detect the external dimensions and surface slag inclusion conditions of the slab. In the current casting system, there will inevitably be unqualified products, and the unqualified rate is about 0.5%. At present, the conventional detection methods include laser and weighing detection. After detecting the unqualified slabs, they can be removed. However, in this case, it will cause waste of aluminum ingot scraps, and subsequent recycling of the discarded slabs is often required, making the entire recycling process more cumbersome.

[0003] In the production of aluminum ingots, the external dimensions of the aluminum ingots are mainly determined by the casting molds. The cross-section of the slab is generally trapezoidal, so that adjacent slabs can be turned over and stacked in a positive and negative manner, increasing the stability of stacking and also improving the stability of transportation after bundling. Moreover, after the cast aluminum ingots are demolded, they are all with the large surface facing down, that is, the larger area surface is attached to the conveyor belt for transportation. However, during subsequent stacking, some slabs often need to be turned over so that their small surfaces face down, so that multiple slabs can be stacked on top of each other. Even when stacking by a robot, a slab turning device needs to be set up. This method has problems such as low efficiency and cumbersome process. Summary of the Invention

[0004] Aiming at the technical problems existing in the background art, the present invention provides a short-process aluminum alloy slab casting system, which can directly remelt the unqualified slabs when detecting the slabs, further simplifying the process flow, and can realize the turning operation of the slabs after detection, facilitating subsequent stacking.

[0005] To achieve the above object, the technical solution provided by the present invention is as follows:

[0006] A short-process aluminum alloy flat ingot casting system includes a flat ingot detection system. The flat ingot detection system includes a conveying device arranged in a T shape. The conveying device includes a first chassis and a second chassis arranged perpendicular to each other. On both sides of the first chassis, a first conveyor belt and a second conveyor belt are respectively arranged. A roller conveying mechanism is arranged between the first conveyor belt and the second conveyor belt. A third conveyor belt is arranged on the second chassis. The roller transmission mechanism includes a number of conveying rollers arranged on the first chassis, and there is a gap for the detection mechanism to extend between the conveying rollers in the middle position and the conveying rollers on both sides. A detection mechanism is arranged in the first chassis. The detection mechanism includes a lifting cylinder, a base, a weighing device, and a roller assembly. The piston rod of the lifting cylinder is connected to the base. The base is slidably arranged on the inner wall of the first chassis. A weighing device is arranged at the upper end of the base. A roller is arranged on the upper part of the weighing device. The roller assembly can extend out of the first chassis through the gap to lift the flat ingot for weighing. A pushing mechanism is arranged on one side of the first chassis. The pushing mechanism is arranged opposite to the second chassis and is used to push the unqualified flat ingots on the roller assembly onto the third conveyor belt on the first chassis.

[0007] Optionally, the roller assembly includes a U-shaped support rod. T-shaped support shafts are respectively arranged at the upper ends of the support rod, and rollers are respectively arranged on both sides of the support shaft. A connecting rod is arranged at the bottom end of the support rod.

[0008] Optionally, a blocking block is arranged on one side of the base close to the first conveyor belt. The blocking block can extend out of the first chassis through the gap between the two conveying rollers to the upper end.

[0009] Optionally, an installation block is arranged on one side of the base close to the second conveyor belt. A slider is arranged on the installation block. An abutting block is slidably arranged on the slider. The abutting block is arranged between the conveying roller and the second conveyor belt. The abutting block and the slider are connected by an elastic connecting piece. A limiting block is arranged on one side of the abutting block. When the bottom end of the limiting block closely adheres to the bottom wall of one of the conveying rollers, the upper end of the abutting block extends out of the first chassis. An L-shaped support block is arranged on one side of the installation block. A turning roller is rotatably arranged at the upper end of the support block. The turning roller is arranged between the two conveying rollers.

[0010] Optionally, rotating shafts are symmetrically arranged on both sides of the turning roller. A bushing is arranged at the upper end of the support block. The rotating shaft is rotatably arranged in the bushing. [[ID=1X]]

[0011] Optionally, sliding shafts are respectively arranged on both sides of the turning roller. Chute grooves are arranged on both sides of the first chassis. The sliding shafts are slidably arranged in the chute grooves.

[0012] Optionally, a discharge chute is provided at the upper end of the first chassis. The discharge chute is arranged opposite to the second chassis and the pushing mechanism. The pushing mechanism includes a pushing cylinder and a pushing block, and the piston rod of the pushing cylinder is connected to the pushing block.

[0013] Optionally, an inclined feeding plate is provided inside the second chassis. The feeding plate is arranged on the side close to the first chassis and above the third conveyor belt.

[0014] Optionally, the short-process aluminum alloy slab casting system further includes a melting furnace, a slab casting system, and a slab palletizing system. The melting furnace, the slab casting system, the slab detection system, and the slab palletizing system are sequentially connected by a conveying device. The slab detection system is used to detect whether the shape dimensions and weight of the slab are qualified. If qualified, the slab is conveyed to the slab palletizing system; if unqualified, the slab is conveyed to the melting furnace for remelting.

[0015] The present invention has the following advantages and beneficial effects:

[0016] In the present invention, the slab detection system includes a conveying device arranged in a T shape. The conveying device includes a first chassis and a second chassis arranged perpendicular to each other. A first conveyor belt and a second conveyor belt are respectively arranged on both sides of the first chassis, and a roller conveying mechanism is arranged between the first conveyor belt and the second conveyor belt. A third conveyor belt is arranged on the second chassis. When the slab reaches the roller conveying mechanism, the lifting cylinder controls the weighing device and the roller assembly to rise synchronously and extend to the upper end of the first chassis to lift and weigh the slab. After weighing, if it is qualified, it resets and continues to be conveyed away; if unqualified, the unqualified slab on the roller assembly is pushed onto the third conveyor belt on the first chassis by the pushing mechanism. This design can quickly and accurately weigh the slab, recycle the unqualified slab, and directly remelt the unqualified slab, further simplifying the process flow.

[0017] Furthermore, a slab flipping mechanism is provided to perform a flipping operation on the qualified slab after detection. Using the detection mechanism, an installation block is arranged on the side of the base close to the second conveyor belt. A slider is arranged on the installation block, and a contact block is slidably arranged on the slider. A limiting block is arranged on one side of the contact block. When the bottom end of the limiting block closely adheres to the bottom wall of one of the conveying rollers, the upper end of the contact block extends to the upper end of the first chassis to limit the qualified slab. When the lifting cylinder continues to extend, the flipping roller continues to rise to lift and flip the slab. At this time, the contact block is limited and will not rise, only playing a role in limiting the slab until the flipping roller completes the flipping operation of the slab. This structure realizes the slab flipping function while using the slab detection mechanism. The overall structure is ingenious and compact, and multiple functions can be concentrated, facilitating subsequent palletizing. Description of the Drawings

Detailed implementation manners

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1

[0038] As Figure 2 shown, a short-process aluminum alloy flat ingot casting system includes a melting furnace 1, a flat ingot casting system 11, a flat ingot inspection system 12 and a flat ingot stacking system 13. The melting furnace 1, the flat ingot casting system 11, the flat ingot inspection system 12 and the flat ingot stacking system 13 are sequentially connected by a conveying device. The flat ingot inspection system 12 is used to detect whether the outer dimensions and weight of the flat ingot 5 are qualified. If qualified, the flat ingot 5 is conveyed to the flat ingot stacking system 13. If unqualified, the flat ingot 5 is conveyed to the melting furnace 1 for remelting. This short-process aluminum alloy flat ingot casting system can directly remelt the unqualified flat ingots 5 when inspecting the flat ingots 5, further simplifying the process flow.

[0039] As Figure 1 、 3As shown in FIG. -16, the flat ingot detection system 12 includes a conveying device arranged in a T shape. The conveying device includes a first chassis 2 and a second chassis 4 arranged perpendicular to each other. A first conveyor belt 21 and a second conveyor belt 22 are respectively arranged on both sides of the first chassis 2, and a roller conveying mechanism is arranged between the first conveyor belt 21 and the second conveyor belt 22; a third conveyor belt 41 is arranged on the second chassis 4. The structures of the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 41 adopt the prior art, such as a chain plate conveying mechanism, etc., and are driven by a motor to drive the chain plate to move to realize the feeding operation of the flat ingot 5. The roller transmission mechanism includes a plurality of conveying rollers 3 arranged on the first chassis 2. A plurality of connection holes 26 are arranged in the middle of the upper end of the first chassis 2. Both ends of the conveying roller 3 are rotatably arranged in the connection holes 26, and there is a gap for the detection mechanism to extend between the conveying roller 3 in the middle position and the conveying rollers 3 on both sides. That is, there is a gap between the conveying rollers 3, and the gap between the middle conveying roller 3 and the adjacent conveying rollers 3 on both sides is large enough to allow the detection mechanism to extend upward, while the gap between the conveying rollers 3 at other positions is small enough to allow the flat ingot 5 to pass through. The rotation of the conveying roller 3 is also driven by a separate motor. An installation groove 25 is arranged in the first chassis 2. The installation groove 25 is located below the conveying roller 3. A detection mechanism is arranged in the installation groove 25. The detection mechanism includes a lifting cylinder 7, a base 71, a weighing device 72, and a roller assembly. The piston rod of the lifting cylinder 7 is connected to the base 71. The base 71 is slidably arranged on the inner wall of the installation groove 25. A weighing device 72 is arranged at the upper end of the base 71. The weighing device 72 can adopt the prior art and does not require additional design. A roller assembly is arranged on the upper part of the weighing device 72. The roller assembly can extend out to the upper end of the first chassis 2 through the gap at the middle conveying roller 3 and lift the flat ingot 5 for weighing. A pushing mechanism is arranged on one side of the first chassis 2. The pushing mechanism is arranged opposite to the second chassis 4 and is used to push the unqualified flat ingot 5 on the roller assembly onto the third conveyor belt 41 on the first chassis 2.

[0040] When the flat ingot 5 reaches the roller conveying mechanism (reaches the position of the middle conveying roller 3), the lifting cylinder 7 controls the weighing device 72 and the roller assembly to rise synchronously and extend out to the upper end of the first chassis 2 to lift the flat ingot 5 for weighing; after weighing, if it is qualified, it resets and continues to be conveyed away. If it is unqualified, the pushing mechanism pushes the unqualified flat ingot 5 on the roller assembly onto the third conveyor belt 41 on the first chassis 2. This design can quickly and accurately weigh the flat ingot 5, recycle the unqualified flat ingot 5, and directly remelt the unqualified flat ingot 5, further simplifying the process flow.

[0041] Furthermore, the idler assembly includes a U-shaped support rod 9. At the upper ends of the support rod 9, T-shaped support shafts 92 are respectively arranged, and idlers 91 are respectively arranged on both sides of the support shafts 92. At the bottom end of the support rod 9, a connecting rod 93 is arranged. At the upper end of the weighing device 72, a number of connecting sleeves 721 are arranged, and the connecting rod 93 is threadedly connected in the connecting sleeves 721. This U-shaped support structure can rise and ascend from the gaps on both sides of the middle conveyor roller 3 to stably lift the flat ingot 5 for weighing. After weighing, if the flat ingot 5 is qualified, the idler assembly descends to place the qualified flat ingot 5 on the conveyor roller 3 and convey it to the second conveyor belt 22. If the flat ingot 5 is unqualified, the pushing mechanism directly pushes the flat ingot 5 on the idler assembly onto the third conveyor belt 41. Moreover, due to the arrangement of the idlers 91, the flat ingot 5 can be smoothly pushed onto the third conveyor belt.

[0042] Secondly, the arrangement of this flat ingot detection system 12 also has an advantage. Refer to Figure 1 , Figure 2 . On the first chassis 2, when the flat ingots 5 are conveyed, they are conveyed horizontally, that is, the long sides of the flat ingots 5 are adjacent to each other. In this way, multiple flat ingots 5 can be conveyed on the first chassis 2 for detection, and at the same time, multiple qualified flat ingots 5 are also conveyed to the next palletizing process. The flat ingots 5 on the second chassis 4 are unqualified flat ingots 5 and are conveyed vertically, that is, the wide sides of the flat ingots 5 are adjacent to each other. Therefore, the width of the second chassis 4 can be set narrower. And since the proportion of unqualified flat ingots 5 in the qualified flat ingots 5 is very small, when the unqualified flat ingots 5 are conveyed vertically on the third conveyor belt 41, the interval time between two adjacent unqualified flat ingots 5 is very long, and there will be no mutual extrusion and collision. This kind of structural arrangement can reduce the volume occupation of the conveying device, can reasonably optimize the conveying direction of the flat ingots 5 according to the number of flat ingots 5 on each conveyor belt, and at the same time, the pushing mechanism directly pushes the unqualified flat ingots 5 onto the third conveyor belt 41 without changing the position and direction of the flat ingots 5.

[0043] Embodiment 2

[0044] Furthermore, a blocking block 73 is arranged on one side of the base 71 close to the first conveyor belt. The blocking block 73 can extend to the upper end of the first chassis 2 through the gap between the two conveyor rollers 3 or the gap between the first conveyor belt 21 and the conveyor roller 3. Such a design aims to limit the conveyed flat ingots 5 and prevent too many flat ingots 5 from accumulating on the conveyor roller 3, which may affect the detection. As Figure 6 shown, at this time, the lifting cylinder 7 descends and the blocking block 73 contracts, and the flat ingots 5 on the first conveyor belt 21 can be freely conveyed to the conveyor roller 3; as Figure 7As shown in the figure, when there is an ingot blank 5 on the conveying roller 3, the lifting cylinder 7 rises, the blocking block 73 rises and extends to the upper end of the conveying roller 3 to block the ingot blank 5 on the first conveyor belt 21, preventing it from reaching the conveying roller 3 and not affecting the detection of the ingot blank 5 on the current conveying roller 3. After the detection is completed, the lifting cylinder 7 descends. By repeating the above steps, the blocking block 73 descends, and the ingot blank 5 on the first conveyor belt 21 can be placed on the conveying roller 3 for detection.

[0045] Embodiment 3

[0046] Furthermore, on one side of the base 71 close to the second conveyor belt 22, there is a mounting block 74. On the mounting block 74, there is a sliding block 75. A contact block 77 is slidably arranged on the sliding block 75. A guiding groove 771 is arranged inside the contact block 77. The sliding block 75 is slidably arranged closely against the inner wall of the guiding groove 771. The contact block 77 is arranged between the conveying roller 3 and the second conveyor belt 22. The contact block 77 and the sliding block 75 are connected by an elastic connecting member 78, such as a spring. The spring is arranged in the guiding groove 771 and one end is fixed in the guiding groove 771, and the other end of the spring is fixedly connected to the sliding block 75. A limiting block 79 is arranged on one side of the contact block 77. When the bottom end of the limiting block 79 closely abuts against the bottom wall of one of the conveying rollers 3, the upper end of the contact block 77 extends to the upper end of the first chassis 2 (as Figure 7 、 8 shown); on one side of the mounting block 74, there is an L-shaped support block 76. A turning roller 10 is rotatably arranged at the upper end of the support block 76. The turning roller 10 is arranged between two conveying rollers 3.

[0047] Such a design can realize the turning function of the ingot blank 5. As Figure 6 shown, at this time, the lifting cylinder 7 descends and the limiting block 79 is arranged away from the conveying roller 3; as Figure 7 shown, at this time, the lifting cylinder 7 just rises so that the supporting roller 91 abuts against the ingot blank 5. At this time, the limiting block 79 also closely abuts against the bottom wall of the conveying roller 3, and the upper end of the contact block 77 extends to the upper end of the conveying roller 3; as Figure 8 shown, when the lifting cylinder 7 continues to rise to weigh the ingot blank 5, the sliding block 75 continues to rise, but the contact block 77 is limited and fixed, and the sliding block 75 rises relative to the contact block 77 and the spring is compressed; as Figure 9 shown, at this time, the qualified ingot blank 5 after detection is conveyed to one side of the contact block 77 and is limited by the contact block 77. At this time, the conveying roller 3 and the turning roller 10 are on the same horizontal line to support the ingot blank 5; as Figure 10As shown, at this time, the lifting cylinder 7 rises, controlling the slider 75, the support block 76, and the turning roller 10 to rise synchronously, pushing up the flat ingot 5. Since one end of the flat ingot 5 is limited by the abutting block 77, the flat ingot 5 is pushed up and turned. During this period, the spring is continuously compressed until the turning roller 10 turns the flat ingot 5 onto the second conveyor belt 22. After the flat ingot 5 is turned over, the lifting cylinder 7 descends and resets.

[0048] In the present invention, on the basis of using the detection mechanism, the flat ingot 5 is lifted and weighed, and after weighing, the unqualified flat ingots 5 can be pushed and recycled, or the qualified flat ingots 5 can be directly conveyed onto the third conveyor belt 41, or the qualified flat ingots 5 can be turned over and then conveyed onto the third conveyor belt 41. With this structure, the entire detection mechanism is integrally arranged, and functions such as weighing, pushing, and turning can be achieved. The overall structure is ingenious, and there is no need to additionally set up an aluminum ingot turning device for stacking later. During the detection, the subsequent turning operation of the flat ingot 5 can be synchronized. The operation is simple and fast, with high efficiency, and only a single lifting cylinder 7 can achieve multiple functions.

[0049] Further, rotating shafts 101 are symmetrically arranged on both sides of the turning roller 10, and a bushing 761 is provided at the upper end of the support block 76. The rotating shaft 101 is rotatably arranged within the bushing 761.

[0050] Further, sliding shafts 102 are respectively arranged on both sides of the turning roller 10, and sliding grooves 24 are provided on both sides of the first chassis 2. The sliding shafts 102 are slidably arranged in the sliding grooves 24 to enhance the lifting guiding accuracy of components such as the turning roller 10 and the overall lifting cylinder 7.

[0051] Further, a discharge chute 23 is provided at the upper end of the first chassis 2. The discharge chute 23 is arranged facing the second chassis 4 and the pushing mechanism. The pushing mechanism includes a pushing cylinder 6 and a pushing block 61. The piston rod of the pushing cylinder 6 is connected to the pushing block 61. As Figure 7 shown, when the flat ingot 5 is placed on the conveying roller 3, the height of the discharge chute 23 is higher than the bottom end of the flat ingot 5, which can limit the flat ingot 5; as Figure 8 shown, when the supporting roller 91 lifts the flat ingot 5, the height of the flat ingot 5 is higher than the discharge chute 23, and the flat ingot 5 can be recycled through the discharge chute 23.

[0052] Further, an inclined feeding plate 42 is arranged inside the second chassis 4. The feeding plate 42 is arranged on the side close to the first chassis 2 and above the third conveyor belt 41. With such a design, after the flat ingot 5 is pushed to a certain position, it will slide onto the feeding plate 42 by its own weight and then slide along the feeding plate 42 onto the third conveyor belt 41. This structure can also shorten the stroke of the pushing cylinder 6.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
