Description

Technical Field

[0001] The utility model relates to the technical field of medium frequency furnaces, in particular to an aluminum system on a medium frequency furnace. Background Art

[0002] At present, the aluminum adding process of medium frequency furnace mainly relies on manual addition, and manual aluminum adding has the following disadvantages: 1. The appearance of each aluminum ingot is about 1 meter long × 0.2 meter wide × 0.2 meter high, and the manual physical labor is heavy; 2. The medium frequency furnace mouth is hot and the working environment is poor; 3. The aluminum ingots added to the medium frequency furnace for the first time have melted, and there are safety risks such as workers slipping and falling into the furnace mouth and aluminum liquid splashing when adding aluminum ingots; 4. The diameter of the furnace mouth is 0.8-0.9 meters, and manual aluminum loading cannot be vertically and densely loaded, and the scaffolding seriously increases the power consumption.

[0003] In order to solve the above problems, we tried to introduce a robotic arm for automatic aluminum addition. The robotic arm was placed within 2 meters of the medium frequency furnace. After the aluminum stack was manually lifted to the designated position, aluminum was automatically added through the robotic arm, which successfully reduced the labor intensity of workers and personnel safety issues.

[0004] However, during use, it was found that the robotic arm was affected by high temperature: 1. The robotic arm was close to the medium frequency furnace, and the high temperature caused a high failure rate of the robotic arm, affecting production; 2. The machine had unclear recognition problems under high temperature conditions, which made it impossible to load the aluminum ingots upright and densely into the medium frequency furnace, causing the scaffolding to seriously increase power consumption.

[0005] Based on this, it is necessary to study an aluminum system on a medium frequency furnace. Utility Model Content

DETAILED DESCRIPTION

[0041] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0042] This embodiment aims to provide an aluminum loading system for a medium frequency furnace, which is mainly used to automatically add aluminum ingots to the medium frequency furnace, in order to solve the problems of high labor intensity and high risk factor of manual aluminum loading, and the influence of high temperature when a robotic arm is used instead of manual labor.

[0043] A medium frequency furnace aluminum system, such as Figure 1 , including an intermediate frequency furnace 1, a material area 2, a mechanical arm 3, a track 4, and a dump truck 5; the material area 2 is arranged away from the intermediate frequency furnace 1, and there are six stacking platforms in the material area 2, on which aluminum ingots are placed. The mechanical arm 3 is arranged in the material area 2, and is mainly used to stack the aluminum ingots on the stacking platform into the dump truck 5, and when stacking, the aluminum ingots are placed in the dump truck 5 in parallel along the extension direction of the track 4, so that when the dump truck 5 is unloading, the aluminum ingots can be loaded upright and densely into the intermediate frequency furnace 1. A track 4 is laid between the material area 2 and the intermediate frequency furnace 1, and the dump truck 5 is arranged on the track 4 and can move along the track 4.

[0044] like Figure 2 The dump truck 5 includes an automatic frame 6, a material box 7 and a dump mechanism 8. The automatic frame 6 is set on the track 4 and can move along the track 4. The automatic frame 6 can be combined with a control system to move and brake on the track 4 according to a predetermined path planning. It is mainly existing technology and will not be repeated here.

[0045] like Figure 2 and Figure 3 The lower left part of the material box 7 is hingedly arranged on the automatic frame 6, and a tipping mechanism 8 is arranged between the material box 7 and the automatic frame 6. The tipping mechanism 8 is mainly used to flip the material box 7 with the hinge point as the center of the circle, so that the material box 7 is in a state of being lower on the left and higher on the right after flipping. Figure 4 and Figure 5, the dumping mechanism 8 includes a first electrically-controlled telescopic rod 801, a middle connecting rod 802, an upper connecting rod 803 and a lower connecting rod 804; in this embodiment, the first electrically-controlled telescopic rod 801 adopts an oil cylinder, and the fixed end of the first electrically-controlled telescopic rod 801 is hingedly arranged on the automatic frame 6, and the telescopic end of the first electrically-controlled telescopic rod 801 is hingedly connected to the middle part of the middle connecting rod 802; both ends of the middle connecting rod 802 are hingedly connected to one end of the upper connecting rod 803 and the lower connecting rod 804 at the same time, that is, the upper connecting rod 803 and the lower connecting rod 804 are each provided with two groups, which are respectively located on both sides of the dumping truck 5; the other end of the upper connecting rod 803 is hingedly connected to the material box 7, and the other end of the lower connecting rod 804 is hingedly connected to the automatic frame 6; when the first electrically-controlled telescopic rod 801 is retracted, as shown Figure 5 , the angle between the upper connecting rod 803 and the lower connecting rod 804 is increased, and the material box 7 is turned counterclockwise with the hinge point between the material box 7 and the automatic frame 6 as the center of the circle, so that the material box 7 is tilted lower on the left and higher on the right, so that the aluminum ingots in the material box 7 have sliding potential energy.

[0046] The material box 7 includes a material bin 701, a bin door 702 and a bin door opening and closing mechanism 703; Figure 5 The silo 701 has an upper opening chamber, which is mainly used to store aluminum ingots. Each aluminum ingot has an appearance of about 1 meter long × 0.2 meters wide × 0.2 meters high. The silo 701 can be loaded with 15-20 aluminum ingots at a time. A discharge port is provided on the left side of the silo 701. The upper end of the silo door 702 is rotatably arranged at the upper left end of the silo 701 through a rotating shaft. The silo door switch mechanism 703 is mainly used to lock the silo door 702. Figure 6 and Figure 7 When the door switch mechanism 703 is closed, the door 702 blocks the discharge port; Figure 7 When the door switch mechanism 703 is opened, the door 702 is unlocked and can rotate with the hinge point between the upper end and the silo 701 as the center, so that the aluminum ingots with sliding potential energy can slide out of the silo 701 from the discharge port.

[0047] The door switch mechanism 703 includes a second electrically-controlled telescopic rod 7031, a first switch rod 7032, a second switch rod 7033 and a slider 7034; the second electrically-controlled telescopic rod 7031 also adopts an oil cylinder, the fixed end of the second electrically-controlled telescopic rod 7031 is fixed to the lower part of the silo 701, and the telescopic end of the second electrically-controlled telescopic rod 7031 is hingedly connected to the lower end of the first switch rod 7032; one end of the second switch rod 7033 is hingedly connected to the middle part of the first switch rod 7032, and the other end is hingedly connected to the slider 7034; a slide groove 7035 adapted to the slider 7034 is horizontally arranged at the lower part of the silo 701, and the slider 7034 is slidably arranged in the slide groove 7035; when the second electrically-controlled telescopic rod 7031 is fully extended, the first switch rod 7032 is vertical and abuts against the left end face of the silo 702 to close the silo 702. The door switch mechanism 703 is mainly used to control the opening and closing of the door 702. Its specific structure is not limited. In other embodiments, a magnetic switch or other mechanisms with equivalent functions can also be used to implement it.

[0048] Furthermore, the first switch rod 7032 is fixedly connected to a switch plate 7037 on the side facing the bin door 702. The first switch rod 7032 is abutted against the bin door 702 through the switch plate 7037, so that the length of the first switch rod 7032 can be shorter, thereby preventing the first switch rod 7032 from obstructing the aluminum ingot when the aluminum ingot slides out, ensuring that the aluminum ingot slides out of the silo 701 smoothly, and improving the accuracy of aluminum loading.

[0049] Furthermore, although there is a control relationship between the second electrically-controlled telescopic rod 7031 and the control system, in order to facilitate the control system to identify the switch state of the warehouse door 702 and form a negative feedback mechanism, a contact switch 7036 is provided at the end of the slide slot 7035. When the second electrically-controlled telescopic rod 7031 is fully extended, the slider 7034 moves to the end of the slide slot 7035 and triggers the contact switch 7036. The contact switch 7036 is communicated with the control system. When the contact switch 7036 is triggered, a signal is fed back to the control system to form a negative feedback, so as to facilitate the control system to verify the current switch state of the warehouse door 702.

[0050] Further, such as Figure 2 The left side of the material box 7 extends outward to the left from the automatic frame 6, so that when the automatic frame 6 is parked in front of the intermediate frequency furnace 1, the left side of the material box 7 is located above the intermediate frequency furnace 1, so that when the dump truck 5 is unloading, the aluminum ingots can be directly discharged vertically to the middle of the intermediate frequency furnace 1, thereby improving the accuracy of aluminum loading.

[0051] Furthermore, tracks 4 are provided on opposite sides of the material area 2, a dump truck 5 is provided on each track 4, a medium frequency furnace 1 is provided at the end of each track 4, a robotic arm 3 is provided in the middle of the two tracks 4, and two dump trucks 5 travel alternately, so that by using one material area 2 and one robotic arm 3, two medium frequency furnaces 1 can be coated with aluminum at the same time, thereby improving resource utilization.

[0052] The specific operation process of this embodiment is as follows: first, the dump truck 5 stops in the material area 2, and the robotic arm 3 stacks the aluminum ingots into the dump truck 5; then the dump truck 5 travels along the track 4 and stops in front of the medium frequency furnace 1, and the dump mechanism 8 operates to flip the material box 7 and keep it in an inclined state, so that the aluminum ingots obtain sliding potential energy; then the bin door switch mechanism 703 opens and unlocks the bin door 702, and the aluminum ingots slide out of the bin 701 and fall into the medium frequency furnace 1, completing the aluminum loading; thereafter, the dump mechanism 8 is reset to reset the bin 701 and the bin door 702; then the bin door switch mechanism 703 is closed and the bin door 702 is locked; finally, the dump truck 5 returns to the material area 2 to prepare for the next round of aluminum loading.
