Description

Technical Field

[0001] The invention relates to the field of aluminum alloy round ingot processing, in particular to a surface grinding processing device for an aluminum alloy round ingot. Background Art

[0002] Aluminum alloy round ingots are made of pure aluminum and recycled aluminum as raw materials. Other elements are added according to international standards or special requirements to improve the deficiencies of pure aluminum in castability, chemical and physical properties. They are suitable for casting and can make castings have good performance. Aluminum alloy round ingots are an important product. During the processing of aluminum alloy round ingots, their surfaces need to be polished to remove excess burrs and impurities on the surface, improve the surface quality and performance of aluminum alloy round ingots, and facilitate subsequent processing.

[0003] Most of the existing grinding devices use grinding belts or grinding wheels to grind the outside of the round ingot. Since the round ingot itself has a certain length, grinding with either a grinding belt or a grinding wheel takes a certain amount of time. Grinding with a grinding belt or a grinding wheel for a long time is prone to excessive grinding pressure, and the debris generated during grinding is prone to adhere to the round ingot, affecting subsequent grinding.

[0004] Therefore, it is necessary to propose a surface grinding and processing device for aluminum alloy round ingots to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a surface grinding and processing device for aluminum alloy round ingots to solve the problem that most existing grinding devices use grinding belts or grinding wheels to grind the outer side of the round ingots.

[0015] Preferably, a second motor is fixed to one side of one of the fixing frames, and a driving shaft of the second motor is connected to the corresponding polishing roller.

[0016] Technical effects and advantages of the present invention: 1. The supporting polishing mechanism can not only support the lower surface of the round ingot when grinding the round ingot, but also rub against the surface of the round ingot when the round ingot rotates, so as to play the role of polishing and auxiliary grinding, and reduce the grinding pressure of the mobile grinding mechanism. The two cylinders can respectively drive the corresponding moving seats to move on the slide rail, so that the two moving seats can move relative to or away from each other, and round ingots of different lengths can be clamped and fixed, and the discharge and unloading of the round ingot can be convenient.

[0017] 2. In the actual operation of the present invention, after the round ingot is clamped and fixed, the third motor is started so that the conveyor belt can drive the mobile vehicle to move along the length direction of the round ingot. Since the round ingot itself is clamped and rotated by the clamping mechanism, the outer side of the round ingot will contact and rub against the rotating grinding belt. When the mobile vehicle moves from one end of the support frame to the other end, the grinding of the outer surface of the entire round ingot can be completed, and the burrs or tiny protrusions on the outer surface of the round ingot can be removed to make the surface smoother, so as to improve the surface quality and performance of the aluminum alloy round ingot, and achieve the purpose of one-time grinding along the length direction of the round ingot, with high grinding efficiency.

[0018] 3. Furthermore, when the mobile grinding mechanism is grinding, the fan is started, and the exhaust port of the fan is connected to the interior of the outer cover. Due to the shape of the outer cover itself, wind will enter the interior of the outer cover, and the wind will be discharged from the air outlet along the outside of the grinding belt, which is convenient for blowing and cleaning the outer surface of the grinding belt. Due to the effect of wind, debris and dust can be prevented from entering the interior of the outer cover, and the debris adhering to the grinding belt during grinding can be blown out. At the same time, when the mobile grinding mechanism moves along the length of the round ingot, the wind will also blow downward from the air outlet onto the round ingot, remove the debris and dust generated by grinding on the round ingot, play a cleaning role, and can dissipate heat for the round ingot and the grinding belt during the grinding process, reducing the pressure of overheating due to grinding.

[0019] 4. In the actual operation of the present invention, after the round ingot is clamped and fixed, the polishing belt can be extended upward by the two first electric push rods so that the upper surface of the polishing belt can fit the outer side of the round ingot. When the round ingot rotates, the outer surface of the polishing belt will rub against the outer side of the round ingot, thereby achieving the effect of polishing the entire round ingot. At the same time, due to the effect of friction, it can also assist the mobile grinding mechanism in grinding and reduce the grinding pressure of the mobile grinding mechanism.

[0020] 5. Furthermore, when the polishing belt is in contact with the round ingot, the grooves can scrape off dirt and impurities adhering to the surface of the round ingot.

[0021] 6. Before polishing, inject kerosene into the groove in advance. When the round ingot rotates and the outer side of the round ingot contacts the upper surface of the polishing belt, the kerosene is applied to the outer side of the round ingot through extrusion force and friction, so that the kerosene and the friction of the polishing belt can remove and decompose the oil stains on the outer side of the round ingot, ensuring that the cleanliness of the surface of the round ingot meets the polishing requirements.

[0022] 7. In the actual operation of the present invention, after the round ingot is polished, the two clamping mechanisms move away from each other. Since the bottom end of the round ingot is supported by the polishing belt, the round ingot loses the clamping force at both ends and falls completely onto the polishing belt. The first electric push rod retracts, driving the polishing belt and the round ingot to descend, so that the polishing belt descends to be flush with the unloading rack. At this time, the third electric push rod is started to push the round ingot to the unloading rack through the push plate to carry out unloading. The polishing belt can also play a role in supporting and unloading. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. 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.

[0036] The present invention provides Figure 1 - Fig.11 The surface grinding and processing device of the aluminum alloy round ingot shown includes a support frame 1, two connecting rods 3 are fixed on both sides of the inside of the support frame 1, and slide rails 4 are fixed on the top of the two connecting rods 3. There are two clamping mechanisms slidingly matched on the two slide rails 4, and the round ingot is clamped between the two clamping mechanisms. A supporting and polishing mechanism is arranged below the round ingot, and a movable grinding mechanism 11 is arranged on one side of the round ingot. The movable grinding mechanism 11 and the supporting and polishing mechanism are both used for grinding the round ingot.

[0037] The supporting polishing mechanism can not only support the lower surface of the round ingot when grinding the round ingot, but also rub against the surface of the round ingot when the round ingot rotates, thereby playing the role of polishing and auxiliary grinding, and reducing the grinding pressure of the mobile grinding mechanism 11.

[0038] The clamping mechanism includes a movable seat 5, the bottom end of which is slidably fitted on two slide rails 4, and the top end of the movable seat 5 is fixed with two shaft holders 7 along the length direction. A connecting shaft 8 is rotatably connected between the two shaft holders 7, and a clamping plate 9 is fixed at one end of the connecting shaft 8 close to the round ingot. The round ingot is clamped between the two clamping plates 9, and the two shaft holders 7 can be used to support the corresponding connecting shafts 8.

[0039] Cylinders 10 are fixed at both ends inside the support frame 1, and the telescopic ends of the two cylinders 10 are fixedly connected to the corresponding moving seats 5 respectively. A first motor 14 is fixed on one of the moving seats 5, and the driving shaft of the first motor 14 is connected to the corresponding connecting shaft 8. When the first motor 14 is started, it can drive the corresponding connecting shaft 8 and the clamping disk 9 to rotate.

[0040] Specifically, the two movable seats 5 are respectively arranged at the two ends of the two slide rails 4, and the two cylinders 10 can respectively drive the corresponding movable seats 5 to move on the slide rails 4, so that the two movable seats 5 can move relative to or away from each other, and round ingots of different lengths can be clamped and fixed. At the same time, the discharge and unloading of the round ingots can be facilitated. When the two movable seats 5 move relative to each other and the two ends of the round ingot are clamped, the first motor 14 can be started to drive the clamped round ingot to rotate through the connecting shaft 8, and the outer side of the round ingot can be rubbed against the movable grinding mechanism 11 and the supporting polishing mechanism to achieve the effect of grinding and polishing.

[0041] The mobile grinding mechanism 11 includes a mobile vehicle 33, and mobile wheels 35 are arranged at the four corners of the bottom end of the mobile vehicle 33. Two guide rails 36 are fixed on one side of the support frame 1. The two guide rails 36 are distributed along the length direction of the support frame 1. The four mobile wheels 35 are respectively slidably matched on the corresponding guide rails 36. The guide rails 36 can support the mobile wheels 35 at the top of the mobile vehicle 33, so that the mobile vehicle 33 can move along a straight line, which can make the movement more stable and will not cause deviation.

[0042] A protective cover 2 is fixed to one side along the length direction of the top of the support frame 1, a conveyor belt 13 is arranged inside the protective cover 2, a moving vehicle 33 is fixed on the conveyor belt 13, and a third motor 32 is fixed to the side of the protective cover 2 away from the fixed seat 12, a driving shaft of the third motor 32 is connected to one of the rotating shafts, and the third motor 32 can use a servo motor, which can drive the moving vehicle 33 to move back and forth on the support frame 1 by rotating forward and reverse.

[0043] The mobile vehicle 33 is fixed on the conveyor belt 13, and fixed seats 12 are fixed at both ends inside the protective cover 2. A rotating shaft is rotatably connected inside the two fixed seats 12, and gears are sleeved on the outer sides of the two rotating shafts. The inner side of the conveyor belt 13 is provided with teeth connected to the two gears, and the conveyor belt 13 is connected to the outer sides of the two gears, so that after the rotating shaft rotates, the conveyor belt 13 can be driven to move for transmission. After the conveyor belt 13 is transmitted and moved, it can drive the mobile vehicle 33 to move along the length direction of the support frame 1.

[0044] In the actual operation of the present invention, after the third motor 32 is started, it can drive the rotating shaft to rotate, and after the rotating shaft rotates, the conveyor belt 13 can be moved, and the movement of the conveyor belt 13 can drive the moving vehicle 33 to move.

[0045] An outer cover 22 is provided on the mobile vehicle 33, and a fan 19 is fixed on the top of the outer cover 22. The exhaust port of the fan 19 is connected to the inside of the outer cover 22. The outer cover 22 is tilted downward on one side of the round ingot and is provided with an air outlet 15. Side plates 18 are fixed on both sides of the outer cover 22. A grinding roller 20 and two second pressing rollers 37 are rotatably connected between the two side plates 18. A grinding roller 20 and two second pressing rollers 37 are distributed in a triangle, and a grinding belt 21 is transmission-connected to the outer side of a grinding roller 20 and two second pressing rollers 37. It should be noted that there is a gap between the inner end of the outer cover 22 and the outer side of the grinding belt 21.

[0046] The outer cover 22 can protect the internal structure, prevent external dust and debris from entering the interior, and avoid clogging and interference problems.

[0047] The outer side of the grinding belt 21 is attached to the outer surface of the round ingot, and a fourth motor 34 is fixed to one side of one of the side plates 18. The driving shaft of the fourth motor 34 is connected to one of the grinding rollers 20. After the fourth motor 34 is started, it can drive the grinding roller 20 and the grinding belt 21 to rotate.

[0048] In the actual operation of the present invention, after the round ingot is clamped and fixed, the third motor 32 is started so that the conveyor belt 13 can drive the moving vehicle 33 to move along the length direction of the round ingot. Since the round ingot itself is clamped and rotated by the clamping mechanism, the outer side of the round ingot will contact and rub against the rotating grinding belt 21. When the moving vehicle 33 moves from one end of the support frame 1 to the other end, the grinding work of the outer surface of the entire round ingot can be completed, and the burrs or tiny protrusions on the outer surface of the round ingot can be removed to make the surface smoother, so as to improve the surface quality and performance of the aluminum alloy round ingot.

[0049] Furthermore, when the mobile grinding mechanism 11 is grinding, the fan 19 is started, and the exhaust port of the fan 19 is connected to the interior of the outer cover 22. Due to the shape of the outer cover 22 itself, wind will enter the interior of the outer cover 22, and the wind will be discharged from the air outlet 15 along the outside of the grinding belt 21, which is convenient for blowing and cleaning the outer surface of the grinding belt 21. Due to the effect of the wind, debris and dust can be prevented from entering the interior of the outer cover 22, and the debris adhering to the grinding belt 21 during grinding is blown out. At the same time, when the mobile grinding mechanism 11 moves along the length of the round ingot, the wind will also blow downward from the air outlet 15 onto the round ingot, removing the debris and dust generated by grinding on the round ingot, thereby playing a cleaning role.

[0050] Two supporting polishing mechanisms are arranged along the length direction of the supporting frame 1, and the supporting polishing mechanism includes a connecting frame 16, the connecting frame 16 is fixed to the bottom end inside the supporting frame 1, a first electric push rod 17 is fixed to the bottom end of the connecting frame 16, the top end of the first electric push rod 17 extends out of the connecting frame 16, and the top of the extended end is connected to a top plate 23, and a fixing frame 27 is fixed on the two top plates 23, and a polishing belt 25 is arranged between the two fixing frames 27, the polishing belt 25 is arranged in an inverted triangle, and a groove 26 is opened on the upper surface of the polishing belt 25 along the length direction, the groove 26 can be filled with kerosene, and the upper surface of the polishing belt 25 is movably fitted to the lower surface of the round ingot.

[0051] The inner side of the polishing belt 25 is respectively connected to two polishing rollers 28 and a first clamping roller 31 by transmission. The first clamping roller 31 is arranged in the middle below the two polishing rollers 28. The two polishing rollers 28 are rotatably connected between the two fixed frames 27. The middle of the two fixed frames 27 are embedded with second electric push rods 29. The top ends of the two second electric push rods 29 are fixed with lifting plates 30. The first clamping roller 31 is rotatably connected between the two lifting plates 30.

[0052] A second motor 24 is fixed to one side of one of the fixed frames 27. The driving shaft of the second motor 24 is connected to the corresponding polishing roller 28. The second motor 24 can drive the polishing roller 28 to rotate, thereby causing the polishing belt 25 to rotate. During specific use, the second motor 24 can be started or not as needed.

[0053] In the actual operation of the present invention, after the round ingot is clamped and fixed, the polishing belt 25 can be extended upward by the two first electric push rods 17 so that the upper surface of the polishing belt 25 fits the outer side of the round ingot. When the round ingot rotates, the polishing belt 25 will rub against the outer side of the round ingot, thereby achieving the effect of polishing the entire round ingot. At the same time, due to the effect of friction, it can also assist the mobile polishing mechanism 11 in polishing and reduce the polishing pressure of the mobile polishing mechanism 11.

[0054] Furthermore, when impurities and dirt are inevitably adhered to the outer side of the round ingot during production or transportation, the present invention provides a groove 26 on the polishing belt 25. When the polishing belt 25 contacts the round ingot, the groove 26 will contact the protruding impurities or dirt, and the groove 26 can scrape off the dirt and impurities adhered to the surface of the round ingot.

[0055] During the production process of aluminum alloy round ingots, a small amount of demoulding grease is applied to the end faces of the mold, the end faces of the ingot tube and the end faces of the extrusion gasket to prevent aluminum from sticking. After the round ingot is demoulded, the grease is easy to adhere to it, which will affect the subsequent polishing, and the grease will be more likely to adhere to dust and impurities.

[0056] Therefore, before polishing, kerosene can be injected into the groove 26 in advance. When the round ingot rotates and the outer side of the round ingot contacts the upper surface of the polishing belt 25, the kerosene is applied to the outer side of the round ingot through extrusion force and friction, so that the kerosene cooperates with the friction of the polishing belt 25 to remove and decompose the oil stains on the outer side of the round ingot, ensuring that the cleanliness of the surface of the round ingot meets the polishing requirements.

[0057] A material unloading rack 6 is arranged on the side of the support frame 1 away from the protective cover 2, and a third electric push rod 39 is fixed on the side of the support frame 1 close to the protective cover 2. The third electric push rod 39 is higher than the material unloading rack 6, and a push plate 40 is fixed on the side of the third electric push rod 39 close to the material unloading rack 6. The bottom end of the material unloading rack 6 is connected to a support block 38, and the bottom end of the support block 38 is fixed to the connecting rod of the support frame 1.

[0058] The two supporting polishing mechanisms are arranged between the two slide rails 4 , and the unloading rack 6 is arranged below the slide rails 4 .

[0059] In the actual operation of the present invention, after the round ingot is polished, the two clamping mechanisms move away from each other. Since the bottom end of the round ingot is supported by the polishing belt 25, the round ingot loses the clamping force at both ends and falls completely onto the polishing belt 25. The first electric push rod 17 retracts, driving the polishing belt 25 and the round ingot to descend, so that the polishing belt 25 descends to be flush with the unloading rack 6. At this time, the third electric push rod 39 is started to push the round ingot to the unloading rack 6 through the push plate 40 to carry out unloading. The polishing belt 25 can also play a role in supporting and unloading.
