[0002] Electric furnace aluminum billet refers to aluminum material in a preliminary forming state produced by an electric furnace smelting process. It is the basic raw material for subsequent aluminum processing and usually has a certain shape and size specifications, such as aluminum ingots, aluminum bars, etc.

[0003] In order to facilitate storage, transportation and subsequent processing, the existing aluminum ingots are generally in the shape of long strips or trapezoids. When forming aluminum ingots, aluminum liquid is poured into the mold, and the mold is generally an open long strip notch. The personnel need to pour the aluminum liquid along the notch. When the pouring speed is too fast, the impact force of the aluminum liquid on the mold is large, which is easy to cause splashing and turbulence. This will cause the distribution of aluminum liquid in the mold to be uneven, and the surface will fluctuate. In addition, the notch of the mold is open, which will form an uneven surface after solidification. The uneven surface will affect the subsequent stacking of aluminum ingots, resulting in gaps between the aluminum ingots that fit together, causing the stacking to be skewed and affecting the stability of the stacking.

DETAILED DESCRIPTION

[0027] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 4 , a finishing equipment for electric furnace aluminum blanks shown in the figure includes a conveyor belt 1, a block for placing aluminum ingots is installed on the conveyor belt 1, and also includes a bracket 2 installed on the outside of the conveyor belt 1, a slide bar 3 is fixedly installed on the bracket 2, a mobile frame 4 is slidably installed on the outside of the slide bar 3, a grinding roller 5 for grinding the surface of the aluminum ingot is rotatably installed on the mobile frame 4, a rotating plate 6 is rotatably installed on the outside of the mobile frame 4, and a grinding power unit 7 for driving the grinding roller 5 to rotate is installed on the rotating plate 6; and a driving member 8 installed on the outside of the bracket 2, which drives the mobile frame 4 to reciprocate along the slide bar 3, a track frame plate 9 is fixed on the bracket 2 through a connecting plate, and docking parts 10 connected to the track frame plate 9 are installed at both ends of the rotating plate 6, and the angle of the rotating plate 6 is adjusted by the movement of the two docking parts 10 and the track frame plate 9;

[0029] In this solution, the driving member 8 drives the moving frame 4 to move along the slide bar 3, and cooperates with the grinding power unit 7 to provide power, so that the grinding roller 5 can grind along the surface of the aluminum ingot, grind and flatten the raised part of the surface of the aluminum ingot, so that the aluminum ingot is more flat and stable when it is stored and stacked later;

[0030] It should be noted that the rotating plate 6 in the present embodiment can rotate due to the movement of the two docking parts 10 at different positions in the track frame plate 9, and can follow the forward and backward movement of the grinding roller 5 and correspondingly drive the forward and reverse rotation of the grinding roller 5, so as to effectively discharge the aluminum chips generated during grinding to the outside, and avoid the aluminum chips remaining on the surface of the aluminum ingot.

[0031] For further information, see Figure 3 , Figure 4 and Figure 6 The grinding power unit 7 includes two grinding motors 11 fixed at both ends of the rotating plate 6 through a motor frame, a driving gear 12 is fixed to the output end of the two grinding motors 11, and a docking gear 13 is fixed to the outer end of the shaft of the grinding roller 5. The driving gear 12 is meshed with the docking gear 13, and then the rotation of the driving gear 12 drives the rotation of the grinding roller 5, and the two grinding motors 11 rotate in opposite directions;

[0032] In this solution, the rotation of the grinding motor 11 is used to drive the gear 12 to rotate, so that the mating gear 13 meshing therewith rotates synchronously. At the same time, because the radius of the driving gear 12 is twice the radius of the mating gear 13, the rotation speed of the grinding roller 5 is faster and the grinding effect is better.

[0033] In this proposal, see Figure 4 and Figure 6 The docking portion 10 includes a rotating rod 14 that is rotatably docked with the outer end of the rotating plate 6, and a roller 15 is fixed to the outer side of the rotating rod 14;

[0034] Also, see Figure 2 , Figure 3 , Figure 7 as well as Figure 8 The shape of the track frame plate 9 is an isosceles trapezoid, the horizontal end length of the top of the track frame plate 9 is greater than the horizontal end length of the bottom, a groove 16 adapted to the roller 15 is opened in the track frame plate 9, and recesses 17 for the roller 15 to pass through are opened at both ends of the track frame plate 9.

[0035] The principle of driving the rotating plate 6 to rotate by moving the docking part 10 in the track frame plate 9 is as follows: first, the roller 15 in the docking part 10 is slidably docked with the groove 16 in the track frame plate 9. When driving the moving frame 4 to move along the slide bar 3, the two rollers 15 in the two docking parts 10 are respectively slidably connected with the grooves 16 at the top and bottom of the track frame plate 9. When it is about to move to the end of the slide bar 3, the roller 15 at one end begins to contact the inclined plates at both ends of the track frame plate 9, and as the moving frame 4 continues to move, the roller 15 begins to move to the inclined plate of the track frame plate 9, and at the same time, the other roller 15 begins to move outward through the notch 17. As the moving frame 4 moves to the end of the slide bar 3, the roller 15 moves from the bottom of the track frame plate 9 through the inclined plate to the top of the track frame plate 9, that is, a rotation adjustment of the rotating plate 6 is completed, so that the other driving gear 12 begins to mesh with the docking gear 13. The whole process is as follows Figure 8 As shown, the reciprocating screw 18 then continues to rotate, driving the movable frame 4 to start moving in the opposite direction along the slide bar 3, thereby driving the grinding roller 5 to start moving in the opposite direction, and the two rollers 15 at the other end of the track frame plate 9 continue to adjust the angle of the rotating plate 6.

[0036] It should be noted that, by adjusting the angle of the rotating plate 6, the two driving gears 12 with opposite directions are engaged with the docking gear 13 in turn, so that the grinding roller 5 has different directions when moving forward and backward, so that each time it moves, the aluminum chips generated by grinding can be ejected in the direction of movement, and then the ejected aluminum chips are collected by an external baffle to prevent the aluminum chips from adhering to the surface of the aluminum ingot and being transported away with the conveyor belt 1.

[0037] In this solution, in order to avoid residual aluminum chips on the surface of the aluminum ingot, brushes 20 are fixed at both ends of the rotating plate 6. The length of the brush 20 is consistent with the length of the grinding roller 5. Each time the rotating plate 6 rotates, the brush 20 at the corresponding end will be driven to move downward and contact the surface of the aluminum ingot. Most of the aluminum chips generated by grinding on the surface of the aluminum ingot will be carried out due to the rotation direction of the grinding roller 5, and some of the residual aluminum chips will be brushed away by the brush 20, so that there is no residual aluminum chips on the surface of the aluminum ingot, which is convenient for recycling the aluminum chips.

[0038] For further information, see Figure 2 and Figure 3 The driving member 8 includes a reciprocating screw 18 rotatably mounted on the bracket 2, a driving motor 19 is fixed to the outer side of the bracket 2 through a motor frame, an output end of the driving motor 19 is fixed to the outer end of the reciprocating screw 18 through a coupling, and the reciprocating screw 18 is threadedly connected to the moving frame 4;

[0039] In this solution, the driving motor 19 generates power to rotate the reciprocating screw 18, thereby driving the movable frame 4 to move back and forth along the slide bar 3, so that the grinding roller 5 can grind the aluminum ingot every time it moves, thereby improving the grinding efficiency.

[0040] In this scheme, the method for grinding the surface of the aluminum ingot to improve the surface flatness of the aluminum ingot includes the following process:

[0041] In the first step, the personnel first place the formed aluminum ingots on the block on the conveyor belt 1, and as the conveyor belt 1 is driven, the aluminum ingots are moved to the bracket 2 in sequence;

[0042] The second step is to provide power through the driving member 8 so that the moving frame 4 can reciprocate along the sliding rod 3;

[0043] The third step is to move the docking part 10 in the track frame plate 9 so that the grinding power unit 7 drives the grinding roller 5 to rotate, and the raised part of the surface of the aluminum ingot is ground and flattened by the grinding roller 5;

[0044] In the fourth step, the polished aluminum ingot is removed by the operation of the conveyor belt 1, and the next aluminum ingot is moved to the bracket 2, and the polishing roller 5 starts to move in the reverse direction. At the same time, the docking part 10 moves in the track frame plate 9, driving the rotating plate 6 to rotate, and replacing the driving gear 12 meshing with the docking gear 13, so that the polishing roller 5 rotates in the reverse direction;

[0045] The fifth step is to repeat the first to fourth steps to achieve batch finishing of the aluminum ingots, grind and flatten the raised parts on the surface of the aluminum ingots to improve the flatness.

[0046] It should be noted that when the grinding roller 5 moves back and forth, the two docking parts 10 on the rotating plate 6 move along the track frame plate 9 and drive the rotating plate 6 to rotate accordingly, so that when the grinding roller 5 moves back and forth, it turns in the opposite direction and can make the aluminum chips generated by grinding be ejected from the front end in the forward direction. At the same time, the surface of the aluminum ingot is cleaned with a brush 20 to avoid residual aluminum chips on the surface of the aluminum ingot. The ejected aluminum chips are recovered through an external baffle to achieve the recycling of the aluminum chips.

[0047] In the present solution, it should be noted that, by rotating the rotating plate 6, the two driving gears 12 are engaged with the docking gear 13 in turn, thereby being able to change the forward and reverse rotation of the grinding roller 5, so that when the grinding roller 5 moves in one direction, the aluminum chips generated by grinding can be ejected in the direction of movement through its own rotation, so that the ejection direction of the aluminum chips is stable and recovery is easier.

[0048] Example 2: Please refer to Figure 3 and Figure 5 This embodiment further explains the first embodiment, and the difference lies in that a detection member 25 for detecting the surface flatness of the aluminum ingot is added. The detection member 25 can achieve targeted grinding, and the grinding effect is better.

[0049] Specifically, two connecting plates 21 are fixed on the mobile frame 4, and the two connecting plates 21 are distributed on both sides of the grinding roller 5. A connecting sleeve 22 is fixed at the bottom of the two connecting plates 21, and a plug rod 23 is slidably inserted in the connecting sleeve 22. A contact wheel 24 is rotatably installed at the bottom of the plug rod 23, and a detection member 25 is installed on the connecting plate 21;

[0050] The detection member 25 includes a button-type pressure sensor 26 fixed on the connecting plate 21 , an end plate 27 fitted with the inner wall of the connecting sleeve 22 is fixed on the top of the insertion rod 23 , and a buffer spring 28 abutting against the button-type pressure sensor 26 is fixed on the end plate 27 .

[0051] In this solution, during the movement of the mobile frame 4, the contact wheel 24 will be driven to move along the surface of the aluminum ingot. During the movement, the contact wheel 24 will squeeze the buffer spring 28 due to contact with the raised part, thereby applying force to the button-type pressure sensor 26. When the pressure value detected by the button-type pressure sensor 26 is larger, the driving motor 19 is controlled to rotate slower, so that the grinding roller 5 moves more slowly, thereby improving the grinding effect on the surface of the aluminum ingot.

[0052] Example 3: Please refer to Figure 3 and Figure 5 This embodiment further illustrates other embodiments, and the difference lies in that a magnetic block 29 is added to facilitate the rotation of the rotating plate 6.

[0053] Specifically, magnetic blocks 29 are fixed at both ends of the top of the track frame plate 9, and the rotating rod 14 is made of metal that is attracted to the magnetic blocks 29. When the roller 15 moves to the high point of the inclined plate end of the track frame plate 9, in order to enable the roller 15 to better enter the top of the track frame plate 9 instead of moving back along the inclined plate, the magnetic blocks 29 are designed to adsorb the rotating rod 14, so that the roller 15 can smoothly enter the top of the track frame plate 9, making the rotation of the rotating plate 6 smoother.
