Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ingot production and processing, in particular to an aluminum ingot demoulding and ingot protecting device. Background Art

[0002] Aluminum ingots are high-purity aluminum metal blocks obtained through a melting and smelting process. Currently, during the continuous casting process, a distributor evenly distributes hot molten aluminum into a mold. A sprocket drives a chain, which in turn moves the mold. The ingot is then solidified using indirect water cooling. When the ingot reaches the tail of the horizontal casting machine, a knocking device strikes the mold, causing it to vibrate and release the ingot.

[0003] During the demolding process of the aluminum ingots, in order to facilitate the subsequent cooling, arrangement and stacking of the aluminum ingots, the aluminum ingots need to fall onto the lower conveyor in a fixed direction. In the prior art, either a fixed arc-shaped structure with rollers is provided to wrap the aluminum ingots and the mold installed on the chain to prevent the aluminum ingots from falling prematurely, or a fixed ingot protection chain is provided to wrap the mold so that the aluminum ingots in the mold will not fall directly after demolding, but will slide down along the arc of the sprocket after demolding and fall onto the lower conveyor or ingot receiving device, or a structure including an ingot protection chain and a spring is provided to prevent the aluminum ingots from falling prematurely after demolding.

[0004] Although the above-mentioned ingot protection structure can protect the integrity of the aluminum ingot to a certain extent, it still has the following problems in actual use: 1. Although the aluminum ingot has been solidified and demolded at the ingot protection, it is still in a high temperature state (about 350°C). At this time, the aluminum ingot is very sticky, and the pin shaft of the roller in the roller arc structure or the pin shaft of the ingot protection chain will be worn, making the pin shaft difficult to rotate, which will cause the rolling friction between the aluminum ingot and the ingot protection structure to change to sliding friction. The appearance of the aluminum ingot is easily damaged during the sliding friction process; 2. Since the ingot protection device is fixedly installed, the distance between it and the sprocket is also fixed. When the cast aluminum ingot is too large or too small or is cast for the second time, the aluminum ingot will be stuck between the chain and the sprocket. Once the ingot is stuck, the resistance of the reducer will increase, causing the equipment to shake during operation, and then cause water ripples to appear on the surface of the aluminum liquid in the mold. In severe cases, it will also cause damage to the reducer or coupling. Utility Model Content

[0005] The utility model provides an aluminum ingot demoulding and protecting device, which solves the technical problems in the prior art that the appearance of the aluminum ingot is easily damaged during transportation and the aluminum ingot is easily stuck due to the different sizes of the aluminum ingots.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions for the aluminum ingot demoulding and protecting device:

[0007] An aluminum ingot demoulding and ingot protecting device, comprising:

[0008] a first drive sprocket, which is arranged on a first coupling, which is mounted on a main shaft of the casting machine, a conveying sprocket for conveying the casting mold is mounted on the first coupling, a conveying chain is mounted on the conveying sprocket, and a casting mold with an outward opening is mounted on the conveying chain;

[0009] a speed increasing box mounted on the support structure and located beside the conveying sprocket, wherein the input end sprocket of the speed increasing box is in driving connection with the first drive sprocket, and the output end sprocket of the speed increasing box is in driving connection with the second drive sprocket, so that the transmission speed of the second drive sprocket is greater than or equal to the transmission speed of the first drive sprocket;

[0010] A tensioning sprocket is located below the speed increasing box and is mounted on the supporting structure via a tensioning assembly. The tensioning assembly includes a horizontally extending sliding assembly mounted on the supporting structure. One end of the sliding assembly facing away from the conveying sprocket is connected to a horizontally arranged spring, and the other end of the spring is fixedly mounted on the supporting structure. The sliding assembly includes a slider, and the tensioning sprocket is rotatably mounted on the slider.

[0011] The passive sprocket is arranged below the conveying sprocket, and the second driving sprocket, the tensioning sprocket and the passive sprocket are connected by a first transmission chain. The first transmission chain contacts the mold toward the side of the conveying sprocket, and its transmission direction is opposite to the transmission direction of the mold.

[0012] The beneficial effects of the aluminum ingot demoulding and protecting device provided by the utility model are:

[0013] 1. After the aluminum ingot is demoulded, since the transmission speed of the second drive sprocket is greater than or equal to the transmission speed of the first drive sprocket, the transmission speed of the first transmission chain is greater than or equal to the transmission speed of the conveyor chain, which can reduce the relative movement speed between the mold and the first transmission chain to zero, thereby minimizing the sliding or friction between the first transmission chain and the mold, reducing the risk of the first transmission chain scratching the surface of the aluminum ingot and ensuring the integrity of the appearance of the aluminum ingot;

[0014] The cam is connected to the transmission gear of the first transmission chain and the transmission gear of the second transmission chain is connected to the transmission gear of the second transmission chain.

[0015] Through the above arrangement, the utility model effectively solves the technical problems in the prior art that the appearance of the aluminum ingots is easily damaged during transportation, and the aluminum ingots are easily stuck due to the different sizes of the aluminum ingots.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] It should be noted that the main idea of the aluminum ingot demoulding and ingot protection device provided by the present invention is: by setting a tensioning sprocket and installing the tensioning sprocket on the slider, the tensioning sprocket is connected to the second driving sprocket and the passive sprocket through the first transmission chain, and the second driving sprocket is located next to the conveying sprocket, the tensioning sprocket is located below the second driving sprocket, and the passive sprocket is located below the conveying sprocket, so that the first transmission chain can form an arc between the second driving sprocket and the passive sprocket that matches the mold in contact with them, and the arc of the first transmission chain can change with the height of the mold and the aluminum ingot in the mold. The sprocket is automatically adjusted according to the different rotations of the first transmission chain to ensure that it is always in contact with the exposed surface of the aluminum ingot in the mold. The tensioning sprocket slides in the horizontal direction as the curvature of the first transmission chain changes, and automatically resets under the action of the spring force after the first transmission chain returns to its original position, thereby ensuring that the aluminum ingot will not get stuck when passing through this place. By setting up a speed increaser, the transmission direction of the second driving sprocket can be opposite to that of the first driving sprocket, and the transmission speed of the second driving sprocket can be greater than that of the first driving sprocket, so as to reduce the sliding and friction between the first transmission chain and the mold, and ensure the integrity of the appearance of the aluminum ingot.

[0034] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.

[0035] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0036] Example 1 of the aluminum ingot demoulding and protecting device provided by the utility model:

[0037] like Figures 1 to 4 As shown, the aluminum ingot demoulding and protecting device includes a first driving sprocket 1, a speed increasing box 2, two second driving sprockets 3, two tensioning sprockets 4 and two driven sprockets 5.

[0038] Regarding the first drive sprocket 1. A first coupling 6 is mounted on the main shaft of the casting machine, a conveying sprocket 7 for conveying the casting mold 8 is mounted on the first coupling 6, a conveying chain is mounted on the conveying sprocket 7, and a casting mold 8 with an outward opening is mounted on the conveying chain. The first drive sprocket 1 is mounted on the first coupling 6.

[0039] Specifically, there are two conveying sprockets 7 , each of which is equipped with a conveying chain, and an installation position for installing the casting mold 8 is formed between the two conveying sprockets 7 .

[0040] Regarding the speed increaser 2 and its connection to the first and second drive sprockets 1 and 3, the speed increaser 2 is mounted on the support structure and located to the left of the conveyor sprocket 7. Its input sprocket 10 is connected to the first drive sprocket 1 via a second transmission chain 17. Its output sprocket 11 is connected to a second coupling 15. The output end of the second coupling 15 is connected to a rotating shaft 16, on which two second drive sprockets 3 are mounted at intervals. The speed increaser 2 is designed to ensure that the transmission speed of the second drive sprocket 3 is greater than or equal to that of the first drive sprocket 1 through the transmission of its internal gears, and that the transmission direction of the second drive sprocket 3 is opposite to that of the first drive sprocket 1.

[0041] Specifically, the second coupling 15 is an overload coupling.

[0042] Regarding the tensioning sprocket 4 and its connection with the second drive sprocket 3 and the passive sprocket 5. The tensioning sprocket 4 is located below the speed increasing gearbox 2 and is mounted on the support structure via a tensioning assembly. The tensioning assembly includes a horizontally extending sliding assembly mounted on the support structure. The left end of the sliding assembly is connected to a horizontally arranged spring 12, and the other end of the spring 12 is fixedly mounted on the support structure. The sliding assembly includes two parallel and horizontally extending sliding shafts 18. Self-lubricating bearings are mounted at both ends of the slider 13. The self-lubricating bearings are sleeved on the sliding shaft 18. The tensioning sprocket 4 is mounted on the slider 13.

[0043] Specifically, the tensioning assembly includes three springs 12 arranged in parallel.

[0044] Specifically, the support structure includes a support frame 9 and a horizontally arranged support surface at the top of the support frame 9. The bottom surface of the support surface is provided with a first mounting plate 19 and a second mounting plate 20 extending downward. The left end of the spring 12 is fixedly mounted on the first mounting plate 19, and the sliding shaft 18 of the sliding assembly is mounted on the second mounting plate 20.

[0045] Specifically, there is one first mounting plate 19, and its extension direction on the horizontal plane is perpendicular to the extension direction of the spring 12; there are four second mounting plates 20, and the four second mounting plates 20 are divided into two groups, each group includes two second mounting plates 20, and the two second mounting plates 20 in each group are respectively used to pass through one end of the sliding shaft 18 to fix the sliding shaft 18.

[0046] Regarding the passive sprocket 5 and its connection with the second drive sprocket 3 and the tensioning sprocket 4. The passive sprocket 5 is arranged below the conveying sprocket 7 and is connected to the second drive sprocket 3 and the tensioning sprocket 4 via a first transmission chain 14. The first transmission chain 14 contacts the mold 8 on the side facing the conveying sprocket 7 to prevent the aluminum ingot in the mold 8 from falling out. The transmission direction of the first transmission chain 14 is opposite to that of the mold 8.

[0047] Specifically, the transmission speed of the second drive sprocket 3 is greater than the transmission speed of the first drive sprocket 1, so that when the conveying chain and the first transmission chain 14 are in contact, when the conveying chain passes the length of a mold 8, the transmission length of the first transmission chain 14 is 2 to 3 mm longer than the length of the mold 8.

[0048] It should be noted that the first transmission chain 14 is a chain with a dust cover to effectively prevent aluminum slag from getting stuck in the chain.

[0049] The working principle of the aluminum ingot demoulding and ingot protecting device provided by the utility model is as follows: when the main shaft of the casting machine rotates, it drives the first coupling 6 to rotate, and the first coupling 6 drives the first driving sprocket 1 to rotate. The first driving sprocket 1 is connected to the input end sprocket 10 of the speed increaser 2 through the second transmission chain 17. Through the transmission of the gear inside the speed increaser 2, the transmission speed of the second driving sprocket 3 connected to the output end sprocket 11 of the speed increaser 2 is greater than the transmission speed of the first driving sprocket 1. The second driving sprocket 3 drives the tensioning sprocket 4 and the driven sprocket 5 to rotate in turn through the first transmission chain 14. The right side of the first transmission chain 14 contacts the mold 8 to ensure that the aluminum ingot will not fall directly after demoulding, and the sliding or friction between the first transmission chain 14 and the mold 8 is minimized, thereby reducing the risk of the first transmission chain 14 scratching the surface of the aluminum ingot and ensuring the integrity of the appearance of the aluminum ingot.

[0050] When the height of the aluminum ingot in the mold 8 is much higher than the height of the mold 8 due to reasons such as a large ingot or repeated casting, when the aluminum ingot passes through the first transmission chain 14, the first transmission chain 14 bulges toward the side of the tensioning sprocket 4 (i.e., bulges to the left) under the action of the mold 8. Since the total length of the first transmission chain 14 is fixed, at this time, the slider 13 will slide to the right along the sliding shaft 18 to allow the mold 8 to pass through the first transmission chain 14, avoiding the aluminum ingot from getting stuck. After passing through the first transmission chain 14, the aluminum ingot falls onto the conveyor belt located below the conveyor sprocket 7;

[0051] After the large ingot passes through the first transmission chain 14, the tensioning sprocket 4 is automatically reset under the action of the spring 12, so that the first transmission chain 14 can resume the normal conveying curvature.

[0052] Example 2 of the aluminum ingot demoulding and protecting device provided by the utility model:

[0053] The main difference between it and Example 1 is:

[0054] In Example 1, the sliding assembly includes two sliding shafts arranged in parallel and extending horizontally, and a slider is installed on the sliding shaft.

[0055] In this embodiment, the sliding assembly includes a horizontally extending sliding groove, in which a sliding block is installed.

[0056] Example 3 of the aluminum ingot demoulding and protecting device provided by the utility model:

[0057] The main difference between it and Example 1 is:

[0058] In Example 1, the tensioning assembly includes three springs arranged in parallel.

[0059] In this embodiment, the tensioning assembly includes one, two, or three or more springs.
