Description

Technical Field

[0001] The invention relates to the technical field of aluminum processing, and in particular to a sawing line feeding system of a turnover mechanism for aluminum alloy ingots. Background Art

[0002] The aluminum alloy melting and casting workshop mainly produces ingots for rolling aluminum plate and strip products, also called aluminum plate ingots, which are one of the main products achieved by alloying with electrolytic aluminum liquid. The process includes smelting, alloying, insulation, purification, casting and sawing. After that, the ingots are sent to the rolling workshop and then, after removing the surface oxide scale and heating, they can be used in the rolling mill to roll out aluminum plates and aluminum coils.

[0003] At present, my country's melting and casting workshops have basically achieved automation from smelting to casting. After casting, the ingots are manually lifted out of the casting machine (also known as the casting well) using a crane and special lifting equipment and laid on the ground (see Figure 1 , Figure 2 ), there are potential safety hazards in the process of lifting the ingots out of the casting pit and laying them on the ground (see Figure 2 ), this is because, the length of the ingot is generally from 7 meters to 9 meters, and currently the longest can be 12 meters long. When the ingot is out of the well, the hoist is hung on the end of the ingot, and it is lifted vertically out of the casting well. When the lower end of the ingot falls on the ground, the ingot is lowered by the crane while releasing the wire rope, that is, the ingot is dragged down by the hook wire rope. As the weight of an ingot ranges from 15 to 40 tons, this process requires high operating skills of the crane operator, and the ground personnel should stay away from the area when lowering it to avoid operating errors and safety hazards caused by the falling of the ingot. Therefore, the difficulty in lowering the ingot and the safety hazards are problems that urgently need to be solved.

[0004] Therefore, a turning mechanism for aluminum alloy ingots with high safety and the ability to automatically turn over the aluminum ingots after casting has become a goal pursued by those skilled in the art. Summary of the invention

[0026] By adopting the above-mentioned technical scheme, the present invention can realize the safe flipping and laying flat of the ingot lifted from the casting pit. In particular, the ingot flipping and laying mechanism is installed on the flipping pit, and the middle part of the frame of the ingot flipping and laying mechanism is provided with rotational support by two supporting mechanisms installed in the platform foundation of the flipping pit. When the frame of the ingot flipping and laying mechanism is turned to an upright state, its lower half (about half of its length) enters into the flipping pit. When the ingot is lifted out vertically from the casting pit, it does not need to be lifted out to the ground completely, and it can be directly transferred into the flipping pit and placed on the frame of the ingot flipping and laying mechanism. At this time, the frame of the ingot flipping and laying mechanism has been driven to rotate to a roughly vertical state by the hydraulic lifting mechanism. Therefore, the ingot can be directly lifted and placed into the ingot slot at the end of the frame. The ingot is leaning against the frame roughly vertically, and then the rotating frame is driven to a horizontal state by the hydraulic lifting mechanism. When the ingot is rotated to a horizontal state along with the rack, the powered roller system on the ingot turning and laying mechanism rotates and outputs the ingot. At this time, a ground roller mechanism docked with the powered roller system can be set on the ground to further transport the ingot horizontally on the ground. Compared with the prior art, since the weight of the ingot is generally between 15 and 40 tons, the turning mechanism of the present invention does not need to be manually operated to lay the ingot down little by little after it is hoisted out of the casting well, thereby improving the safety of the turning process. Therefore, the ingot turning and laying mechanism of the present invention can achieve safe laying down of the ingot. A powered roller system is provided on the ingot turning and laying mechanism, thereby achieving horizontal roller conveying of the ingot without the need for horizontal lifting with special lifting tools. This makes the entire transportation process automatic, safe and reliable, and avoids potential safety hazards during the lifting process. Since the ingot turning and laying device is adopted and directly installed on the turning pit, the turning pit can be set adjacent to the casting well and communicated with the casting well. The ingot can be hoisted out of the casting well about half and then transferred into the turning pit and placed into the ingot turning and laying device. For the newly-built melting and casting workshop building, the building height can be reduced by about half of the height of the ingot, thus saving the building construction cost.

[0027] Furthermore, the present invention arranges two ingot guiding bars on both sides of the frame base structure near the ingot slot, and vertical rollers are arranged on both sides of the frame base structure, which can make the ingot easier to operate when it is hung on the frame and the ingot will not deviate when walking on the frame roller.

[0028] Furthermore, the rollers, the ground rollers and the transfer vehicle rollers are made into symmetrical cones with thick ends and thin middle, which can make the ingot move along the center on the rollers without deviating from the center.

[0029] Furthermore, the present invention provides two locking mechanisms on the support mechanism, which are used to lock the frame in a horizontal position or an upright position respectively when maintenance or replacement of the hydraulic cylinder is required, so that the equipment can be inspected and maintained. When in a locked state, the lock pin position sensor will give a signal to the control system, and at this time, it is in a locked state, and all operating mechanisms will not start.

[0030] Furthermore, the present invention provides two stop arms on both sides of the connecting base as a limiting mechanism, which is used to limit the frame from flipping to the upright position to prevent it from over-flipping. The preferred solution of the limiting mechanism is to directly set it at the bottom of the connecting base of the hydraulic lifting mechanism, and to extend the two stop arms in the horizontal direction.

[0031] Furthermore, the buffer base at the bottom of the ingot slot of the present invention can reduce the impact force when the ingot falls into the ingot slot.

[0032] Furthermore, the present invention provides a flip angle detection mechanism at the end of the flip shaft, so that the flip angle can be detected and transmitted to the control system for automatically controlling the flip to a specified upright position and a horizontal position.

[0033] The present invention adopts the feeding system of the sawing line of the above-mentioned turning device, by arranging a ground roller mechanism at the tail end of the turning mechanism, and arranging a transfer trolley mechanism for transferring ingots between the ground roller mechanism and the feeding roller of the sawing line. Therefore, it is possible to realize safe and convenient automatic turning of the ingots, and realize safe transportation and automatic loading. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the preferred embodiments cannot be used to limit the protection scope of the present invention.

[0051] See also Figure 4 , the figure shows a preferred embodiment of the present invention, a turning device for aluminum alloy ingots, which includes: an ingot turning and laying mechanism 1, used to turn the ingot from the vertical state lifted out of the casting well to the horizontal state, the ingot turning and laying mechanism 1 is arranged on a turning pit 4, the turning pit 4 is roughly rectangular, its length and width should be able to accommodate the length and width of the ingot turning and laying mechanism 1 turned to the horizontal state, and its depth should be greater than half the length of the ingot turning and laying mechanism 1 turned to the vertical state. Preferably, the turning pit 4 is arranged adjacent to the casting well 200, and the side adjacent to the casting well 200 is connected to the casting well, so that the ingot can be directly placed in the ingot turning and laying mechanism 1 after being lifted out of the casting well 200.

[0052] See also Figure 3 , Figure 3 It is a schematic diagram of the working state of the ingot turning and laying mechanism 1, which is installed on the turning pit 4 and can be switched between a horizontal position and an upright position (roughly 80-90 degrees upright). When it is turned to the upright state, it is used to receive the ingot. After the ingot is hoisted out of the casting well, it is directly hoisted into the ingot turning and laying mechanism 1, and then the ingot turning and laying mechanism 1 is rotated to a horizontal state, and transported by the power roller system 12 (described in detail later) thereon.

[0053] See also Figure 5-15 Specifically, the ingot turning and laying mechanism 1 comprises:

[0054] A frame 11, which includes: a roughly planar frame base structure 111, the frame base structure 111 is used to carry ingots, the frame base structure 111 is formed of structural steel arranged vertically and horizontally, and a pedal 18 is also provided on the frame base structure 111 for maintenance personnel to stand. It can roughly carry the area of ​​an ingot; there is a U-shaped ingot slot 112 at one end of the frame base structure 111. In this embodiment, the ingot slot 112 is formed by connecting one end of an L-shaped member 119 to one end of the frame base structure 111. Obviously, it can also be formed by: one side of a component with a U-shaped cross-section is connected to one end of the frame base structure 111, or a U-shaped ingot slot 112 is directly formed at one end of the frame base structure 111. The U-shaped ingot slot 112 formed at the end is used to place the ingot. The frame base structure 111 is rotatably mounted in the upper foundations on both sides of the turning pit 4 through two supporting mechanisms 13. The supporting mechanisms 13 are mounted in the foundations on both sides of the turning pit 4. When the frame base structure 111 is rotated to an upright state, about half of the length of the frame base structure 111 is rotated into the turning pit 4. When the frame base structure 111 is rotated to a horizontal state, the frame base structure 111 is located above the ground, and the powered roller system 12 on the frame base structure 111 can output the ingots horizontally on the ground. At this time, a ground roller mechanism docking with it can be designed on the ground to further transport the ingots.

[0055] The ingot turning and laying mechanism 1 also includes a powered roller system 12. In this embodiment, it includes six rollers 125 arranged on the frame base structure 111 and parallel to the turning axis (i.e., the center lines of the turning axes 115 on the two supporting mechanisms 13) and a roller driving mechanism for driving the rollers 125 to rotate. Three rollers 125 are respectively arranged on both sides of the supporting mechanism 13. The roller driving mechanism includes a roller driving motor 121 and a chain transmission mechanism 123; there are two roller driving motors 121, which are respectively arranged below both sides of the frame 11; the chain transmission mechanism 123 is arranged between the roller driving motor 121 and the roller 125 adjacent to the roller driving motor 121, and between adjacent rollers 125, for transmitting the power of the roller driving motor 121 to each roller 125; the two roller driving motors 121 are respectively used to drive the rollers 125 on both sides of the supporting mechanism 13.

[0056] The ingot flipping and laying mechanism 1 also includes a hydraulic lifting mechanism 14, which is arranged below the end of the frame 11 opposite to the ingot slot 112, and is used to drive the frame 11 to flip between a horizontal state and an upright state; the hydraulic lifting mechanism 14 includes a connecting base 144 installed at the bottom of the flipping pit 4. In this embodiment, the lower ends of the two hydraulic cylinders 142 are hinged to the connecting base 144, and the upper ends are hinged to the frame basic structure 111 of the frame 11; in this embodiment, more specifically, the connecting base 144 is composed of a horizontal mounting plate and a vertical mounting plate vertically arranged at the rear end of the horizontal mounting plate. The horizontal mounting plate and the vertical mounting plate are pre-buried in the foundation of the flip pit 4. Two hinge seats 143 are arranged between the horizontal mounting plate and the vertical mounting plate. The lower end of the hydraulic cylinder 142 is hinged to the hinge seat 143 through a hinge shaft 141. Two hinge seats 143 are arranged under the frame basic structure 111. The upper end of the hydraulic cylinder 142 is hinged to the two hinge seats 143 under the frame basic structure 111 through the hinge shaft 141.

[0057] The aluminum alloy ingot turning device of the present invention is used when the ingot is solidified and the crystallizer rises. The ingot is pushed out of the wellhead surface by the hydraulic cylinder and is in a nearly upright state. First, the ingot turning and laying mechanism 1 is lifted and rotated to the upright position by the hydraulic lifting mechanism 14. Figure 4As shown, the position is preferably close to vertical, preferably about 80 degrees to the ground. Then, the ingot is lifted vertically from the casting well 200 by a crane and a special lifting device, and moved to the bottom ingot slot 112 of the ingot turning and laying mechanism 1 on the turning pit 4. The ingot is tilted against the roller 125 of the frame base structure 111. At this time, the frame base structure 111 of the ingot turning and laying mechanism 1 is in an 80-degree state. Then, the hydraulic lifting mechanism 14 falls back to make the frame 11 turn to a horizontal position. At this time, the ingot is horizontally output from the ingot turning and laying mechanism 1 through the driving roller 125 of the roller drive mechanism through the power roller system 12. At this time, in actual application, a ground roller mechanism can be docked at the output position of the ingot turning and laying mechanism 1 to transport the ingot horizontally to the designated position. Then, the ingot turning and laying mechanism 1 is lifted and rotated to the upright position by the hydraulic lifting mechanism 14, waiting for the next ingot to be turned and output.

[0058] It can be seen that the aluminum alloy ingot flipping device of the present invention can realize that the ingot is safely turned from the vertical state of lifting to the horizontal state, and is output horizontally. In particular, the ingot flipping and laying mechanism 1 is arranged in the flipping pit 4. When it is turned to the horizontal state, it can be horizontally docked with a ground roller mechanism to output the ingot. Therefore, the present invention does not need to use a sling to lift it to the ground and then lay it flat little by little. It can realize automatic flipping and automatic output. The biggest advantage is that its safety is greatly improved, avoiding the potential safety hazards in horizontal lifting, and can realize the automatic control of ingot feeding. See Figure 4 In this example, the turning pit 4 is arranged adjacent to the casting well 200 (casting machine), and the turning pit 4 extends all the way to be connected with the casting well 200; the advantage of this is that when the ingot is ejected by the casting lifting cylinder 201 and lifted out of the casting well 200 by a crane and special tools, it can be directly placed in the ingot turning and laying mechanism 1 for turning without being lifted out of the ground, thereby greatly reducing the height of the ingot lifted out of the casting well, reducing the difficulty of the lifting workers' operation, improving safety, and also reducing the height of the melting and casting workshop building. The building height can reduce the height of the ingot by about half, saving the building construction cost.

[0059] See also Figure 5-8The turning device of aluminum alloy ingots of the present invention, further, as a preferred embodiment, the frame 11 also includes: two ingot guide bars 114 arranged on both sides of the frame basic structure 111 and close to the L-shaped member, the upper ends of the ingot guide bars 114 are in an open shape tilted outward; vertical rollers 116 for guiding the movement of the ingot are arranged on both sides of the frame basic structure 111. The ingot guide bars 114 and the vertical rollers 116 play a guiding role when the ingot is suspended on the frame basic structure 111 to prevent the ingot from deviating. On the other hand, the vertical rollers 116 play a guiding role when the ingot is horizontally transported to the ground roller mechanism 2 to prevent it from deviating.

[0060] See also Figure 5-8 Further, as a preferred embodiment, the frame 11 further includes a buffer base 113 disposed at the bottom of the ingot slot 112. The buffer base 113 can be made of impact-resistant soft material, thereby reducing the excessive impact force when the ingot falls into the bottom of the ingot slot 112, thereby preventing the equipment from being damaged by the excessive impact force.

[0061] See also Fig.10 , 11 , further, as a preferred embodiment, the support mechanism 13 is used to provide support for the frame 11 to rotate, and includes: a support seat 131 fixedly installed on both sides of the turning pit 4, and a turning bearing seat 132 arranged on the support seat 131; the frame base structure 111 of the frame 11 is provided with an axle seat 117 on both sides, two turning shafts 115 for rotation, one end of the turning shaft 115 is arranged in the axle seat 117 through a self-lubricating bearing, and the other end is installed in the turning bearing seat 132 through a self-lubricating bearing. Through the support seat 131 installed in the foundation on both sides of the turning pit 4, the frame 11 can be rotatably installed on the support seat 131 on both sides of the frame base structure 111 through two turning shafts 115. The turning bearing seat 132 of the ingot turning and laying mechanism 1 is designed for heavy load bearing, the bearing is a self-lubricating bearing 133, and a bearing baffle 134 is provided at the end.
