Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy production equipment, and particularly relates to a production equipment for aluminum alloy round ingots. Background Art

[0002] Aluminum is widely used in various industries of the national economy due to its excellent properties. The mechanical properties of pure aluminum are not high and it cannot bear large loads. Aluminum alloy made by adding some alloys to pure aluminum retains the advantages of low density and corrosion resistance, and its relative specific strength exceeds that of some alloy steels, and it gradually begins to replace materials such as wood, steel, and plastic. Aluminum alloy round ingots are common products in the aluminum smelting process and are made by casting. During casting, the aluminum alloy is melted and poured into a mold. After it cools and solidifies, the aluminum alloy round ingot is taken out of the mold. Due to its good corrosion resistance, thermal conductivity, plasticity and other characteristics, aluminum alloy round ingots are widely used in the fields of architecture, aviation, automobiles, etc.

[0003] Cooling is an important step in the production process of aluminum alloy round ingots. The existing cooling methods mostly adopt air cooling, that is, directly placing the product flat outdoors. Although cooling can be achieved, it takes a long time to completely cool the product, and there is a defect of low cooling efficiency; while using the water cooling method, although this method is fast and can improve the surface quality of the casting to a certain extent, its disadvantages are also obvious. In the case of rapid cooling, excessive stress will be generated, resulting in damage or deformation of the casting.

[0004] Therefore, referring to a cooling device for aluminum alloy round ingots with the application number 201822213038.3 in the prior art, it includes an air compressor, a swing box, an oil cylinder and a column supported on the ground. The top of the swing box is open, and the periphery and bottom of the swing box are closed. A hinge seat A is arranged at the bottom of the swing box, a hinge seat B is arranged on the side wall of the swing box, and a coil pipe is also welded at the bottom of the swing box. The hinge seat A is hinged to the acting end of the piston rod of the oil cylinder, the hinge seat B is hinged to the column, a gantry supported on the ground is erected outside the swing box, and an air outlet pipe is fixed in the cross beam of the gantry. The above patent cools the aluminum alloy round ingot by air through the air outlet pipe, and cools the aluminum alloy round ingot by water through the coil pipe. By combining air cooling and water cooling, the cooling rate of the aluminum alloy round ingot is increased, and at the same time, it is ensured that excessive stress will not be generated, and the aluminum alloy round ingot placed inside is rolled by the swing of the swing box to improve the cooling efficiency.

[0005] However, in the prior art, only one layer of aluminum alloy round ingots can be placed in the swing box. If the number of aluminum alloy round ingots is too large and multiple aluminum alloy round ingots need to be stacked vertically in multiple layers, first, the multiple aluminum alloy round ingots on the upper layer will block the downward flow of the cooling air, and second, it will also affect the rolling amplitude of the multiple aluminum alloy round ingots. If the length of the swing box is set longer, the floor area of the swing box is too large and does not meet the on-site production requirements. In summary, the prior art is not suitable for the cooling of a large number of aluminum alloy round ingots. Summary of the Invention

[0006] The present invention aims to provide a production device for aluminum alloy round ingots, so as to provide a swing box with a multi-layer structure for the cooling of a large number of aluminum alloy round ingots.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A production device for aluminum alloy round ingots includes a swing box. A plurality of partition plates are fixedly arranged in the swing box from top to bottom. The plurality of partition plates divide the internal space of the swing box into a plurality of cooling chambers. The swing box is bolted with baffles for closing each cooling chamber. Each cooling chamber is provided with an air outlet groove. The swing box is fixedly provided with an air inlet pipe. An air outlet sub-pipe is communicated between each air outlet groove and the air inlet pipe. The air outlet sub-pipe is provided with a first valve; it also includes a coil pipe arranged inside each partition plate. The swing box is fixedly provided with a drain pipe and a water inlet pipe. Each coil pipe is communicated between the drain pipe and the water inlet pipe. The water inlet pipe is also provided with a second valve for controlling the water inlet of each coil pipe.

[0009] The working principle and beneficial effects of the present invention:

[0010] According to the number of aluminum alloy round ingots to be cooled, the method from top to bottom is selected to be placed in a plurality of cooling chambers respectively. That is, after laying a flat layer (sufficient quantity) of aluminum alloy round ingots in the upper cooling chamber, the lower cooling chamber is placed.

[0011] According to the number of cooling chambers, the corresponding first valve and second valve are respectively opened to ensure that the air outlet groove blows air towards the cooling chamber where the aluminum alloy round ingots have been placed, and to ensure that the cooling water passes through the coil pipes where the aluminum alloy round ingots have been placed, thereby avoiding waste of cooling water and energy and improving the cooling efficiency. High-pressure air is blown into the air inlet pipe and the air outlet sub-pipe through an air compressor. The high-pressure air blows towards the aluminum alloy round ingots through the air outlet groove for air cooling. Cooling water is introduced into the water inlet pipe. The cooling water flows into the coil pipes. The cooling water absorbs the heat in the cooling chamber, thereby realizing the combination of air cooling and water cooling. The heated cooling water is discharged outwards through the drain pipe. Moreover, the swing box swings left and right to realize the rolling of the aluminum alloy round ingots, so that all surfaces of the aluminum alloy round ingots can be air-cooled and water-cooled, and the high-temperature aluminum alloy round ingots can be cooled in a short time.

[0012] This solution is provided with multiple cooling chambers compared with the prior art to solve the problems that when cooling a large number of aluminum alloy round ingots in the prior art, the upper aluminum alloy round ingots will block the downward flow of the cooling air, and also affect the rolling amplitude of the aluminum alloy round ingots, resulting in poor cooling effect of the aluminum alloy round ingots. At the same time, it also solves the problem of large floor area of the swing box.

[0013] Optimally, it further includes a bracket. The bracket is fixedly provided with a water pump. The water pump and the water inlet pipe are connected with a water inlet hose, and the air compressor and the air inlet pipe are connected with an air outlet hose. High-pressure water is pumped into the water inlet pipe by the water pump. Moreover, the water inlet hose and the air outlet hose have the characteristics of flexible deformation and are suitable for the swing of the swing box.

[0014] Optimally, the swing amplitude of the swing box is -15 to +15 degrees. The aluminum alloy round ingots are conducive to rolling under this swing amplitude.

[0015] Optimally, the shape of the swing box is rectangular.

[0016] Optimally, each cooling chamber is provided with multiple rolling grooves for the aluminum alloy round ingots to roll respectively. Each rolling groove is for 1 aluminum alloy round ingot to roll, avoiding mutual influence between the aluminum alloy round ingots, so that the aluminum alloy round ingots can roll sufficiently.

[0017] Optimally, the number of the cooling chambers is 3 to 8. Brief Description of the Drawings

[0022] The following is further detailed through specific embodiments:

[0023] The reference numerals in the attached drawings of the specification include: water inlet hose 1, water inlet pipe 2, second valve 3, air inlet hose 4, air inlet pipe 5, baffle 6, swing box 7, air outlet groove 8, aluminum alloy round ingot 9, air outlet sub-pipe 10, partition 11, first valve 12, coil pipe 13, air outlet hole 14, drain pipe 15.

[0024] Embodiment: A production device for aluminum alloy round ingots includes a swing box 7. For the specific method of how the swing box 7 swings left and right, refer to the prior art 201822213038.3 - An aluminum alloy round ingot cooling device, and the content does not belong to the protection scope of this application, so it will not be elaborated here. There are many ways to achieve the left - right swing of the swing box 7 in the prior art. For example, the bottom of the swing box 7 is hinged to the ground, and the side of the swing box 7 is pushed by a cylinder, etc.

[0025] As Figure 1 and Figure 2 shown, six layers of partition plates 11 are fixedly arranged in the swing box 7 from top to bottom. The six layers of partition plates 11 divide the internal space of the swing box 7 into five cooling chambers. Baffles 6 for closing each cooling chamber are bolt - connected to the front side and the rear side of the swing box 7. As Figure 2 shown, an air outlet groove 8 is fixedly arranged in each cooling chamber. As Figure 4 shown, the air outlet groove 8 is provided with a plurality of air outlet holes 14.

[0026] As Figure 3 shown, an air inlet pipe 5 is fixedly arranged on the right side of the swing box 7. An air outlet sub - pipe 10 is fixedly connected and communicated between each air outlet groove 8 and the air inlet pipe 5. Each air outlet sub - pipe 10 is provided with a first valve 12; it also includes a coil pipe 13 fixedly arranged inside each layer of partition plate 11. The swing box 7 is fixedly provided with a drain pipe 15 and a water inlet pipe 2. Each coil pipe 13 is fixedly communicated between the drain pipe 15 and the water inlet pipe 2. The water inlet pipe 2 is also fixedly provided with a second valve 3 for controlling the water inlet of each coil pipe 13. The top of the water inlet pipe 2 is fixedly connected with a water inlet hose 1, and water is pumped into the water inlet hose 1 by a water pump. The top of the air inlet pipe 5 is fixedly provided with an air inlet hose 4, and air is pumped into the air inlet hose 4 by an air compressor. Moreover, the water inlet hose 1 and the air inlet hose 4 are reserved with sufficient lengths for the left - right swing of the swing box 7.

[0027] Moreover, the unit - time flow rate of water in the water inlet pipe 2 is greater than the sum of the unit - time flow rates of water in all coil pipes 13. In this solution, according to the number of aluminum alloy round ingots 9 to be cooled, they are placed in the five cooling chambers respectively in a top - down manner. That is, the baffle 6 on the front side is opened, and after a sufficient number of aluminum alloy round ingots 9 are placed in the upper - layer cooling chamber, the lower - layer cooling chamber is placed, and then the baffle 6 on the front side is installed.

[0028] According to the number of aluminum alloy round ingots 9 placed in the cooling chamber, the corresponding first valve 12 and second valve 3 are opened respectively to ensure that the air outlet groove 8 blows air towards the cooling chamber where the aluminum alloy round ingot 9 has been placed, and to ensure that the cooling water passes through the coil pipe 13 where the aluminum alloy round ingot 9 has been placed, thereby avoiding waste of cooling water and energy and improving the cooling efficiency. High-pressure air is blown into the air inlet pipe 5 and the air outlet sub-pipe 10 by an air compressor. The high-pressure air blows towards the aluminum alloy round ingot through the air outlet groove 8 and the air outlet holes 14 for air cooling. The water inlet pipe 2 passes through the cooling water, and the cooling water flows into the coil pipe 13. The cooling water absorbs the heat in the cooling chamber, thereby realizing the combination of air cooling and water cooling. The heated cooling water is discharged outwards through the drain pipe 15.

[0029] Compared with the prior art, five layers of cooling chambers are provided in this solution to solve the problems that when the prior art cools a large number of aluminum alloy round ingots 9, the upper-layer aluminum alloy round ingots 9 will block the downward flow of the cooling air, and will also affect the rolling amplitude of the multiple aluminum alloy round ingots 9, resulting in poor cooling effect of the aluminum alloy round ingots 9. At the same time, the problem of large floor area of the swing box 7 is also solved.

[0030] For those skilled in the art, without departing from the technical concept of the present invention, multiple deformations and improvements can also be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
