Description

Technical Field

[0001] The invention relates to the technical field of aluminum rod production equipment, and in particular to an aluminum rod casting explosion-proof production line. Background Art

[0002] Aluminum rod is a kind of aluminum product. It has a simple molding mold, a stable aluminum crystal structure, and is easy to transport and process. It is a widely circulated aluminum product. The casting process of aluminum rods includes melting, purification, impurity removal, degassing, slag removal and casting. At present, aluminum rod production usually adopts the method of melting recycled aluminum products at high temperature, then passing the aluminum liquid into the aluminum rod mold, and using cooling water to harden the aluminum liquid into aluminum rods.

[0003] During casting, the aluminum rod is usually placed vertically above the cooling water pool when it is formed. The molten aluminum rod falls into the cooling water pool by its own weight, and the heat is transferred to the cooling water through the aluminum rod surface that has been formed on the outside, so that the aluminum liquid in the center of the aluminum rod that has not yet hardened gradually hardens and forms, thereby cooling the molten aluminum rod as a whole quickly. However, due to the direct contact between the molten aluminum rod and the cooling water, when the molten aluminum rod is poorly formed in the mold and the hardness is insufficient, the molten aluminum rod will deform, and even the middle part will break due to severe deformation. The aluminum liquid in the center of the aluminum rod directly contacts the cooling water, causing a large amount of water to evaporate, and an explosion accident will occur. Summary of the invention

[0004] Based on this, in order to solve the above problems, the present invention provides an aluminum rod casting explosion-proof production line, and its specific technical solution is as follows:

[0043] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0044] like Figure 1 and Figure 2 , Figure 3 , Figure 4 As shown, an explosion-proof production line for casting aluminum bars in one embodiment of the present invention comprises:

[0045] The melting and casting tank 1 is provided with an aluminum liquid outlet;

[0046] The cooling device 2 includes a first cooling part 3 and a second cooling part 4. The first cooling part 3 includes a forming cylinder 31 arranged at the aluminum liquid outlet and a first cooling assembly 32 arranged outside the forming cylinder 31. The second cooling part 4 includes a conveying roller 41 arranged at the end of the forming cylinder 31 and a second cooling assembly 42.

[0047] The material separation device 5 includes a material separation plate 51 arranged at the end of the forming cylinder 31, and a material separation driving cylinder 52 for driving the material separation plate 51 to switch between a material separation state and a material passing state; in the material separation state, the material separation plate 51 is attached to the end of the forming cylinder 31; in the material passing state, the material separation plate 51 is lifted to the top of the forming cylinder 31.

[0048] The above-mentioned explosion-proof production line for casting aluminum rods drives the partition plate 51 to switch to the partition state through the partition driving cylinder 52, and passes the molten aluminum into the forming cylinder 31. The molten aluminum is cooled by the first cooling assembly 32 arranged on the outside of the forming cylinder 31. After the molten aluminum at the front end of the forming cylinder 31 is cooled into molten aluminum rods, the partition driving cylinder 52 drives the partition plate 51 to switch to the material passing state, and the molten aluminum rods are pushed away from the forming cylinder 31 by the molten aluminum, thereby realizing the continuous production of molten aluminum rods. At the same time, since the molten aluminum rods will not directly contact with the cooling water during the hardening and molding process of the forming cylinder 31, safety accidents caused by the contact between the molten aluminum and the water are avoided.

[0049] In one embodiment, the first cooling assembly 32 includes a cooling cylinder 321 disposed outside the forming cylinder 31, and a first water cooling unit 322. A first cooling space is formed between the forming cylinder 31 and the cooling cylinder 321. The first water cooling unit 322 is used to pump cooling water to the first cooling space. In this way, the cooling water is pumped to the first cooling space by the first water cooling unit 322, and the aluminum liquid in the forming cylinder 31 transfers heat to the water in the first cooling space through the cylinder wall, and the aluminum liquid is cooled and formed as the water flows.

[0050] In one embodiment, the first water cooling unit 322 includes a first water pump; the cooling cylinder 321 is provided with a water inlet at one end away from the molten casting tank 1 and a water outlet at one end close to the molten casting tank 1, and the first water pump pumps water from the water inlet into the first cooling space. In this way, since the temperature of the cooling water is relatively low when it just enters the first cooling space, the front part of the aluminum liquid of the formed aluminum rod is first cooled by the cooling water with a relatively low temperature, so as to facilitate the continuous forming of the molten aluminum rod; at the same time, the volume of the aluminum liquid gradually increases during the process of the aluminum liquid changing from liquid to solid, which plays a certain pushing role, so as to facilitate the removal of the molten aluminum rod from the forming cylinder 31.

[0051] In one embodiment, a material pushing device 6 is further included; the material pushing device 6 includes a forming round rod 61 disposed at the bottom of the melting and casting tank 1, and a material pushing component 62 driving the forming round rod 61, and the forming round rod 61 is adapted to the inner cylinder cavity of the forming cylinder 31. In this way, the forming round rod 61 is driven by the material pushing component 62 to push out the molten aluminum rod, so as to avoid the forming aluminum rod being blocked in the forming cylinder 31 and affecting the production efficiency.

[0052] In one of the embodiments, the pushing component 62 includes a pushing bracket 63, a pushing drive assembly 64 fixedly arranged on the pushing bracket 63, a dividing barrel 65 movable along the axial direction of the forming barrel 31 relative to the pushing bracket 63, and a dividing drive assembly 66 for driving the dividing barrel 65 to move; the inner cylinder cavity of the dividing barrel 65 is adapted to the forming round rod 61; the aluminum liquid outlet at the bottom of the melting tank 1 is provided with an arc structure adapted to the outer cylinder surface of the dividing barrel 65. In this way, the dividing cylinder 65 is driven by the dividing drive component 66 to move toward the direction approaching the forming cylinder 31, and part of the molten aluminum is separated in the inner cylinder cavity of the dividing cylinder 65 and the forming cylinder 31. After the first cooling component 32 cools the molten aluminum in the forming cylinder 31, the molten aluminum in the forming cylinder 31 gradually hardens and takes shape, and the forming round rod 61 is driven by the pushing drive component 64 to make the molten aluminum rod in the forming cylinder 31 be formed and pushed out at the same time; when the forming round rod 61 enters the forming cylinder 31, the dividing drive component 66 drives the dividing cylinder 65 to move away from the forming cylinder 31. When the molten aluminum rod is completely pushed out of the forming cylinder 31, the dividing drive cylinder 52 drives the dividing plate 51 to switch to the dividing state, and the forming round rod 61 retracts to the original position, and the molten aluminum enters the forming cylinder 31 again. Repeating the above steps can realize continuous forming of the molten aluminum rod.

[0053] like Figure 1 and Figure 5 , Figure 6 As shown, in one embodiment, the second cooling assembly 42 includes a cooling fan 43 and a first air cooling unit 44. The first air cooling unit 44 is provided at a first wind box 441 above the conveying roller 41, and a plurality of first air nozzles 442 are provided at the bottom of the first wind box 441. The cooling fan 43 is connected to the first wind box 441 through a cooling pipe 45, and cools the formed aluminum bar on the conveying roller 41 through the first air nozzles 442. In this way, the cooling fan 43 blows cold air into the cooling pipe 45, so that the first air nozzles 442 on the first wind box 441 cool the formed aluminum bar on the conveying roller 41, thereby reducing the temperature of the formed aluminum bar and completing the stable production of the formed aluminum bar.

[0054] In one embodiment, an auxiliary air nozzle is further provided at the bottom of the first air box 441, and the auxiliary air nozzle is provided on both sides of the first air nozzle 442. In this way, the auxiliary air nozzle and the first air nozzle 442 are used to cool the formed aluminum rod on three sides, thereby accelerating the cooling efficiency of the formed aluminum rod and improving production efficiency.

[0055] In one embodiment, the conveying roller 41 includes a conveying bracket 411 and a plurality of conveying rollers 412 arranged at intervals on the conveying bracket 411; the second cooling assembly 42 also includes a second air cooling unit 46, the second air cooling unit 46 includes a second wind box 461 arranged on the conveying bracket 411, and a plurality of second air nozzles 462 connected to the second wind box 461, and the second air outlet of the second air nozzle 462 is arranged between two conveying rollers 412. In this way, the second air nozzle 462 cooperates with the first air nozzle 442 to achieve synchronous cooling of the upper and lower sides of the formed aluminum bar, accelerate the cooling efficiency of the formed aluminum bar, and improve production efficiency.

[0056] In one embodiment, the second cooling assembly 42 further includes a second water cooling unit 47, and the second water cooling unit 47 includes a first spray group 471 disposed on the first wind box 441. In this way, through the cooperation of the first air cooling unit 44 and the second water cooling unit 47, the effect of synchronous cooling of air cooling and water cooling is achieved, the cooling efficiency of the formed aluminum rod is accelerated, and the production efficiency is improved.

[0057] In one embodiment, the first spray group 471 includes a vertical spray head and auxiliary spray heads arranged on both sides of the vertical spray head. In this way, the vertical spray head and the auxiliary spray head form a spray area with a fan-shaped cross section greater than 180°, which accelerates the cooling efficiency of the formed aluminum rod and improves production efficiency.

[0058] In one embodiment, the second cooling assembly 42 further includes a water return tank 48 disposed on the support bracket 411. Specifically, the water return tank 48 is connected to the circulating water pool through a pipeline. In this way, the water sprayed by the first spray group 471 can be prevented from being sprayed onto the ground and other working areas through the water return tank 48, and the water can be recycled through the water return tank 48, which is energy-saving and environmentally friendly.

[0059] like Figure 7 and Figure 8 As shown, in one of the embodiments, it also includes a material collecting device 7, which includes a material collecting trough body 71 arranged at the end of the forming cylinder 31, and a conveying component 72 for conveying the material collecting trough body 71; the conveying component 72 includes a horizontal moving component 73 and a lifting moving component 74, the horizontal moving component 73 is used to drive the material collecting trough body 71 to move horizontally, and the lifting moving component 74 is used to drive the material collecting trough body 71 to move up and down.

[0060] In one embodiment, the lifting and moving assembly 74 includes a base, a workbench, an articulated rod group and a screw rod group; the articulated rod group includes a first rod seat, a second rod seat, a first articulated rod and a second articulated rod; one end of the first articulated rod is fixedly connected to the base, and the other end is fixedly connected to the workbench; the first rod seat is arranged at the hinge of the first articulated rod, and the second rod seat is arranged at the hinge of the second articulated rod; the screw rod group drives the first rod seat and the second rod seat to move closer to or away from each other; the horizontal moving assembly 73 includes a first track and a first trolley arranged on the first track, and the lifting and moving assembly 74 is arranged on the first trolley. During the trial operation, there is a possibility that the aluminum liquid may fall into the aggregate tank body 71 before cooling and hardening. In this way, the screw rod group is used to drive the first rod seat and the second rod seat to move away from each other, thereby realizing the upward movement of the loading tray collecting trough body 71, so that the collecting trough body 71 is closer to the gap between the first cooling part 3 and the second cooling part 4, and the scrap aluminum material that has not been cooled and hardened by the aluminum liquid can fall into the collecting trough body 71; when the collecting trough body 71 is loaded with scrap aluminum material, the screw rod group drives the first rod seat and the second rod seat to move closer to each other, and the collecting trough body 71 drops to a preset height, which is convenient for the next conveying action.

[0061] In one embodiment, the horizontal moving assembly 73 further includes a second track and a second trolley disposed on the second track, the second track being disposed perpendicularly to the first track; the second trolley is provided with a track seat that can be connected to the first track, and the first trolley can move from the first track to the track seat. In this way, after the first trolley moves from the first track to the track seat, the second trolley moves along the second track, thereby realizing the conveying action of the collecting trough body 71 in a 90° reversing route, with a compact structure and convenient for saving working space.

[0062] like Figure 4As shown, in one of the embodiments, the material separation device 5 also includes a limiting connecting rod assembly, which includes a positioning seat, a triangular seat arranged on the positioning seat, a first connecting rod connecting the triangular seat and the material separation plate 51, a positioning rod connecting the output end of the material separation drive cylinder 52 and the middle of the first connecting rod, and a second connecting rod connecting the output end of the material separation drive cylinder 52 and the triangular seat, and a positioning convex edge adapted to the first connecting rod is provided on the positioning rod, and the cylinder body of the material separation drive cylinder 52 is hinged on the positioning seat. In this way, when the output end of the material separation drive cylinder 52 extends, the material separation plate 51 rotates with the hinge point as the center of the circle, and the positioning convex edge on the positioning rod presses on the first connecting rod, thereby limiting the material separation plate 51 to be in a material separation state, and the working state of the material separation plate 51 can only be switched by driving the material separation plate 51 in the extending direction of the output end of the material separation drive cylinder 52, and the structure is stable and reliable.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
