Example 1

Referring to fig. 1, the utility model discloses a high-purity aluminum ingot sampling device, which comprises a supporting base 1, a drilling assembly 5, a positioning assembly 6 and a cutting assembly 4.

The supporting base 1 is provided with a supporting surface 27 and a sampling groove 28, the supporting surface 27 is horizontally arranged and is used for supporting the aluminum crystal ingot 23 to be sampled, the sampling groove 28 extends along the vertical direction and penetrates through the supporting surface 27, the bottom of the aluminum crystal ingot 23 is provided with a sampling surface 26 to be sampled, and the sampling surface 26 is positioned above the sampling groove 28. The cutting assembly 4 is located at one side of the sampling groove 28 and faces the side wall of the aluminum ingot 23 for cutting the aluminum ingot 23 in the horizontal direction to form a horizontal cut surface. The positioning assembly 6 is located below the ingot for positioning the aluminium ingot 23. The drilling assembly 5 is accommodated in the sampling groove 28, the drilling assembly 5 comprises a sampling drill bit 13, the sampling drill bit 13 is a hollow drill bit and faces the sampling surface 26 of the aluminum ingot 23, and the sampling drill bit 13 can move upwards to drill the aluminum ingot 23. The sampling drill 13 is pushed to the cutting surface, and the sample is cut off in cooperation with the cutting assembly, thereby completing the sampling of the aluminum ingot 23.

As shown in fig. 5, the aluminum ingot 23 has a hollow conical shape, and has a cylindrical cavity therein, i.e., the positioning cavity 24. The bottom also has a flat surface to enable the aluminum ingot 23 to rest on the flat surface. The aluminum ingot 23 is irregularly shaped and has a large weight, and usually can be 30kg or more. Manual sampling by staff is very inconvenient. The conventional sampling apparatus is not capable of sampling the aluminum ingot 23.

The high-purity aluminum crystal ingot sampling device firstly positions the aluminum crystal ingot 23 placed on the supporting surface 27 through the positioning component 6, so as to ensure that the aluminum crystal ingot 23 cannot shake in the process of sampling. Next, the aluminum ingot 23 is transversely cut by the cutting means 4, and the aluminum ingot 23 is partially cut to form a horizontal cut surface. The aluminium ingot 23 is then drilled by the drilling assembly 5. The sampling drill 13 of the drilling assembly 5 is a hollow drill with its cutting edge facing upwards, capable of cutting the aluminium ingot 23 to form a cylindrical aluminium ingot sample 25. When the sampling drill 13 is advanced to the cut-off face, the cylindrical sample 25 is cut off and falls into the hollow drill. As the sampling drill 13 withdraws from the aluminum ingot 23, the sample 25 is withdrawn from the sampling drill 13, thereby completing the sampling of the aluminum ingot 23.

As shown in fig. 5, in a general case, the cutting assembly 4 only needs to cut the aluminum ingot 23 once. If it is desired to obtain samples 25 of different heights, the aluminum ingot 23 may be cut twice by the cutting assembly 4. Specifically, the method comprises the following steps that firstly, the cutting assembly 4 cuts the higher position of the aluminum ingot 23 once, and after the cutting is finished, the drilling assembly 5 drills the aluminum ingot 23 to obtain a first sample, wherein the height of the first sample is higher. The sampling drill bit 13 of the drilling assembly 5 pushes out the aluminum ingot 23. Then, the cutting unit 4 cuts the lower position of the aluminum ingot 23 for the second time, and after the cutting is completed, the drilling unit 5 drills the aluminum ingot 23 to obtain a second sample, and the second sample is lower in height.

Therefore, the high-purity aluminum ingot sampling device can conveniently and efficiently sample the aluminum ingot 23, and can drill samples 25 of the aluminum ingot 23 with different specifications according to actual requirements.

Referring to fig. 1, in the present embodiment, the supporting surface 27 is U-shaped and partially surrounds the positioning assembly 6. The support surface 27 is of U-shaped design to facilitate ingot placement and removal. Specifically, the bearing surface 27 includes an arcuate segment and a feed segment. The feeding sections extend along the horizontal direction, the number of the feeding sections is two, and the two feeding sections are arranged at intervals and are respectively positioned on two sides of the positioning assembly 6. Typically, the aluminum ingot 23 is fed from one end of the feed section and gradually moves in a direction toward the arcuate section. Through setting up the interval between two feeding sections, can be convenient for staff or arm carry out the material loading. The two ends of the arc section are respectively connected with the two feeding sections, and the shape of the arc section is adapted to the shape of the horizontal section of the aluminum ingot 23 so as to accommodate the aluminum ingot. Specifically, the arcuate segment is semi-circular. The sampling slot 28 extends through the arcuate section of the bearing surface 27.

Further, an upwardly extending stop wall is provided at the outer edge of the support surface 27 for guiding the aluminum ingot 23. During the feeding process, the aluminum ingot 23 enters from the outer end of the feeding section, and the aluminum ingot 23 is finally positioned right above the positioning unit and the sampling groove 28 along with the gradual shrinkage of the arc section.

Referring to fig. 1 and 2, in the present embodiment, a positioning component 6 of the high-purity aluminum ingot sampling device is located at one side of a drilling component 5, and includes a lifting column 8 and a positioning block 9. The lifting column 8 is movable in the vertical direction. The aluminum crystallization ingot 23 is conical, a positioning cavity 24 with a downward opening is arranged in the aluminum crystallization ingot, the positioning cavity 24 is cylindrical, a positioning unit is located right below the positioning cavity 24, and the lifting column 8 is connected with the positioning block 9 and used for driving the positioning block 9 to move upwards to the inside of the positioning cavity 24. The number of the positioning blocks 9 is plural, and the plurality of positioning blocks 9 uniformly encircle the periphery of the lifting column 8 and can move along the direction away from the lifting column 8 so as to abut against the inner side wall of the positioning cavity 24, thereby positioning the aluminum ingot 23.

In particular, the positioning assembly 6 may employ an internal-bracing jaw comprising: the hydraulic lifting device comprises an external expansion type clamping block (namely a positioning block 9), a hydraulic telescopic rod 7 and a hydraulic lifting column 8 (namely a lifting column 8). When the aluminum ingot 23 is placed, the internal supporting type clamping jaw (positioning component 6) is lowered, so that the aluminum ingot is placed conveniently. The lifting column 8 is a hydraulic lifting column 8, and can drive the hydraulic telescopic rod 7 and the positioning block 9 to ascend, so that the hydraulic telescopic rod and the positioning block enter the positioning cavity 24 of the aluminum crystallization ingot 23. The hydraulic telescopic rod 7 extends along the horizontal direction, the inner side of the hydraulic telescopic rod is connected with the upper end part of the lifting column 8, and the outer side of the hydraulic telescopic rod is connected with the positioning block 9. The number of the hydraulic telescopic rods 7 is a plurality of the same as the number of the positioning blocks 9. The hydraulic telescopic rods 7 are uniformly distributed around the lifting columns 8, and the hydraulic telescopic rods 7 can synchronously extend or synchronously retract along the horizontal direction, so that the positioning blocks 9 are driven to be outwards opened to be abutted against the inner surface of the positioning cavity 24 of the aluminum ingot 23, and the aluminum ingot 23 is clamped; or a plurality of hydraulic telescopic rods 7 drive the positioning blocks 9 to retract inwards so as to release the aluminum ingot 23. The positioning block 9 is connected with the lifting column 8 through the hydraulic telescopic rod 7.

Illustratively, the number of the positioning blocks 9 and the number of the hydraulic telescopic rods 7 are 3, and the 3 hydraulic telescopic rods 7 can be synchronously extended or retracted in the horizontal direction to drive the 3 positioning blocks 9 to move in the direction away from the lifting column 8 or in the direction approaching the lifting column 8. The hydraulic telescopic rod 7 drives the positioning block 9 to move to abut against the inner side wall of the positioning cavity 24, so that the aluminum crystal ingot 23 is clamped.

Further, the positioning block 9 is provided in the vertical direction, and therefore, the movement of the aluminum ingot 23 in the horizontal direction can be restricted. When the positioning block 9 is abutted against the inner side wall of the positioning cavity 24, friction is generated between the outer surface of the positioning block 9 and the inner side wall of the positioning cavity 24, and further movement of the aluminum ingot 23 in the vertical direction can be restricted. The positioning assembly 6 can realize positioning of the aluminum ingot 23. Preferably, the clamping force applied to the inner side wall of the positioning cavity 24 (i.e. the pressure applied to the inner side wall of the positioning cavity 24 by the positioning block 9) is 300-1600N, and in this pressure range, the aluminum ingot 23 can be clamped without damaging the inner side wall of the aluminum ingot 23. Still more preferably, the clamping force is preferably 500-1500N, and specifically includes: 500. 800, 1100, 1400N. The lifting speed of the lifting column 8 is in the range of 10-30mm/min; preferably, the lifting speed of the lifting column 8 is 20-28mm/min, and specifically comprises: 22. 24, 26, 28mm/min.

Furthermore, since the positioning cavity 24 of the aluminum ingot 23 is cylindrical, in order to increase the contact area between the positioning block 9 and the inner side wall of the positioning cavity 24, the outer side wall of the positioning block 9 is provided with an arc surface, and the radian of the arc surface is adapted to the shape of the inner side wall of the positioning cavity 24. By increasing the contact area between the positioning block 9 and the positioning cavity 24, the positioning assembly 6 can better position the aluminum ingot 23.

Referring to fig. 4, in the present embodiment, the cutting assembly 4 includes a circular saw cutter 19 and a propulsion unit 21. The saw blade of the circular saw cutter 19 is horizontally disposed and faces the side wall of the aluminum ingot 23. The propulsion unit 21 extends in a horizontal direction, the direction of extension of the propulsion unit 21 being on the same extension as the central radial axis of the aluminium ingot 23. The propulsion unit 21 is connected to the circular saw cutter 19 for driving the circular saw cutter 19 to move in a direction approaching the aluminum ingot 23 so that the circular saw cutter 19 cuts the side wall of the aluminum ingot 23.

Specifically, the propulsion unit 21 may be a hydraulic push rod, a pneumatic push rod, an electric push rod, or the like. Preferably, the feed speed of the propulsion unit 21 is in the range of 20-50mm/min. In this embodiment the feed speed of the propulsion unit 21 is kept in the range of 30-40 mm/min. Within this speed range, the operator is better able to control the progress of the circular saw cutter 19. Illustratively, the propulsion unit 21 is a hydraulic ram, and its running speed may be adjusted in multiple stages, where the multiple stages of adjustment include: 30. 32, 34, 36, 38, 40mm/min.

Preferably, the rotational speed of the saw blade of the circular saw cutter 19 ranges from 1500-2000rpm. In this embodiment, the rotational speed of the circular saw cutter 19 is 1700 to 1900rpm, and in this rotational speed range, the circular saw cutter 19 can effectively cut off the aluminum ingot 23. Illustratively, the rotational speed of the circular saw cutter 19 may include 1700, 1750, 1800, 1850, 1900rpm, in particular.

Still further, in order to obtain aluminum ingot samples 25 of different heights, the height of the circular saw cutter 19 in the cutting assembly 4 needs to be adjusted to cut the aluminum ingot 23 at different height positions. The present cutting assembly 4 includes a lifting support base 221, and the lifting support base 221 can be lifted. The propulsion unit 21 and the circular saw cutter 19 are mounted on the elevation support base 221 to be elevated in synchronization with the elevation support base 221. The lifting support base 221 can be subjected to stepless adjustment, and the height of the lifting support base is adjusted to be 38-70mm so as to meet the sampling requirement of the aluminum ingot sample 25. The circular saw cutter 19 and the propulsion unit 21 are fixed to the lifting support base 221 by the fixing block 20, and the propulsion unit 21 and the circular saw cutter 19 can be fixed to the lifting support base 221, so that the risk caused by the possibility that the circular saw cutter 19 falls down is reduced.

Referring to fig. 1 and 3, in the present embodiment, the drilling assembly 5 includes a motor 14, a lifting unit, and a moving unit. The moving unit comprises a guide rail 10 and a sliding block 11, wherein the guide rail 10 is installed on the supporting base 1 and is positioned in the sampling groove 28. The guide rail 10 extends along the longitudinal direction of the support base 1, and the slider 11 is slidably connected to the guide rail 10 and is movable along the extending direction of the guide rail 10. Specifically, the moving unit further includes a hydraulic rod 15, and the hydraulic rod 15 is connected to the slider 11. The central axis direction of the hydraulic rod 15 coincides with the extending direction of the guide rail 10, and is used for driving the slider 11 to slide along the extending direction of the guide rail 10. Preferably, the hydraulic lever 15 is moved at a speed in the range of 15-24mm/min. Illustratively, the hydraulic ram 15 may move at a speed of 20mm/min as the ram 11 is driven to move, so as to ensure that the operator is assured that the sampling drill 13 is aligned with the sampling location of the aluminum ingot 23.

Further, the elevating unit is mounted on the slider 11. The lifting unit includes a lifting base 17, and the lifting base 17 is movable in a vertical direction. The motor 14 is installed on the lifting base 17, and its output is connected with the sampling drill bit 13 for driving the rotation of sampling drill bit 13, sampling drill bit 13 is the ring shape, and the cutting edge sets up. The moving component is used for driving the lifting unit and the sampling drill bit 13 to move to the sampling position of the aluminum ingot 23, and the lifting unit is used for driving the sampling drill bit 13 to push upwards through the lifting base 17 so as to cut and sample the aluminum ingot 23.

For example, the motor 14 may be a commercially available motor with a power of 1KW and an output shaft rotation speed of 300r/min, so as to drive the sampling drill 13 to rotate at a rotation speed of 300r/min, thereby performing longitudinal sampling cutting on the aluminum ingot 23.

Specifically, the lifting unit further includes a screw 16 and a guide bar 12, and both the screw and the guide bar 12 extend in the vertical direction. The lower ends of the lead screw 16 and the guide rod 12 are connected with the sliding block 11, and the upper ends are connected with the lifting base 17. The screw rod is in threaded connection with the lifting base 17, and the guide rod 12 penetrates through the lifting base 17 and is used for guiding the lifting base 17. The movable gear is mounted on the screw 16, and the screw 16 is driven to rotate by a motor or other equipment, so that the lifting base 17 can be lifted up and down smoothly. Preferably, the moving speed of the lifting base 17 is 5-20mm/min, namely the pushing speed of the sampling drill 13. Illustratively, the lifting base 17 is moved at a speed of 5mm/min at which the sampling drill bit 13 assembly is able to drill the aluminum ingot 23 and avoid the sampling drill bit 13 from advancing too fast, resulting in chipping of its cutting edge. Moreover, maintaining the speed of advance of the sampling drill 13 within a low speed range allows the operator sufficient reaction time to retract the sampling drill 13 in the event of an accident during the sampling process.

Further, the drilling assembly 5 further comprises an ejector rod 18. An ejector rod 18 is mounted on the slide 11 and extends upwardly through the center of the lifting base 17 and the sampling drill 13. The ejector rod 18 is used to eject the sample 25 from the sampling drill 13 when the lifting base 17 is lowered. Specifically, during sampling, the lifting base 17 drives the motor 14 and the sampling drill 13 to rise synchronously, while the ejector rod 18 remains unchanged in height. After sampling is completed, the cylindrical sample 25 is dropped into the hollow drill. The lifting base 17 drives the sampling drill bit 13 to move downwards, and the ejector rod 18 can eject the cylindrical sample 25 in the hollow drill bit as the height of the sampling drill bit 13 gradually decreases to the height of the ejector rod 18.

It should be noted that, in the existing sampling equipment, the hollow drill is pushed forward to sample through the electric push rod, one side of the segregation ingot is perforated in the process, then the sample in the hollow drill is taken out, the length of the drill sample is about 180mm, and the phenomenon of clamping can occur in the long-stroke drilling process due to the fact that the high-purity aluminum is extremely easy to stick a cutter.

In order to avoid the phenomenon of drill bit jamming, in this embodiment, the high-purity aluminum ingot sampling device further comprises a control unit (not shown in the figure), and the control unit comprises a controller and a position sensor. The controller is preset with a target pushing distance and a tool retracting distance, wherein the target pushing distance is the distance of the sampling drill bit 13 to be pushed in the aluminum crystal ingot 23, the tool retracting distance is the distance of the sampling drill bit 13 needing tool retracting operation, and the tool retracting distance is smaller than or equal to the target pushing distance. The position sensor is electrically connected to the controller for detecting the actual advance distance of the sampling drill 13 and transmitting the actual advance distance to the controller. The control unit is electrically connected with the drilling assembly 5 and is used for comparing the received actual pushing distance with the retracting distance, and when the actual pushing distance reaches the retracting distance, the sampling drill bit 13 is controlled to withdraw the aluminum crystal ingot 23 so as to complete one retracting operation. The control unit is further configured to control the sampling drill 13 to continue to drill the aluminum ingot 23 upwards after the withdrawal operation of the sampling drill 13 is completed, and repeat the above operations until the actual pushing distance of the sampling drill 13 reaches the target pushing distance. Specifically, the position sensor may be a commercially available position sensor, and the controller may be a commercially available industrial personal computer or the like.

In other words, the target advance distance of the hollow drill (i.e., the depth of upward advance of the drill) was set to 40mm, and the retracting distance was set to 10mm. Every 10mm of the hollow drill bit is drilled upwards, the cutter is required to be retracted once, and the hollow drill bit is withdrawn from the aluminum ingot 23 so as to discharge aluminum scraps.

Illustratively, the sample height is 38mm, and the target advance distance that the pilot bit (sampling bit 13) needs to drill up is set to 40mm. It should be noted that the sample height is usually required to be lower than the target pushing distance, so as to ensure that the sawed sample 25 is completely cut off and can fall down by itself. Before the drilling is performed, the height of the cutting assembly 4 needs to be set, and the setting height of the cutting assembly 4 is 38mm. It is easy to understand that the cutting height of the cutting assembly 4 is the sample height. The cutting assembly 4 adjusts the height of the circular saw cutter 19 to a position 38mm from the bottom surface of the aluminum ingot 23 by lifting the supporting base 221, and then the circular saw cutter 19 advances forward to cut the aluminum ingot 23, leaving a cut-off section.

Then, the sampling drill 13 is started, and the lifting assembly drives the sampling drill 13 to push upwards. The controller controls the sampling drill 13 to perform a retracting operation every 10mm of upward drilling through a set program therein. When the cutter is retracted, the sampling drill bit 13 completely withdraws from the aluminum crystal ingot 23 so as to discharge aluminum scraps, then drilling is carried out again, the cutter is reciprocated for 4 times, and finally, the aluminum scraps in the drilling and cutting process can be normally discharged, and the drill bit is prevented from being blocked. After the sampling drill 13 completes the drilling, the sample 25 after sawing can fall off by itself because the drilling depth is greater than the height of the cut surface.

Referring to fig. 1, in the present embodiment, the high-purity aluminum ingot sampling apparatus further includes an aluminum scrap conveying belt 3, and the aluminum scrap conveying belt 3 is located at one side of the supporting base 1 and is used for conveying aluminum scraps to a recycling place. The support base 1 is further provided with a chip removal port 2, specifically, the chip removal port 2 is a groove arranged on the right side of the support base 1, and the bottom surface of the chip removal port can be obliquely arranged so as to guide aluminum scraps onto the aluminum scraps conveying belt 3. The chip discharge port 2 is located at a side close to the rotational direction of the circular saw cutter 19 and faces the aluminum chip conveyor 3 for discharging aluminum chips generated during cutting by the circular saw cutter 19 onto the aluminum chip conveyor 3. Illustratively, when the circular saw cutter 19 rotates clockwise (turns rightward), aluminum scraps generated by cutting are splashed rightward by the cutting force, and at this time, the exhaust port 2 is provided at the right side of the circular saw cutter 19, so that the splashed aluminum scraps can be received better. Similarly, when the circular saw cutter 19 rotates counterclockwise, the exhaust port 2 is provided at the left side of the circular saw cutter 19.

Referring to fig. 1, the following will specifically describe the working procedure of the present high purity aluminum ingot sampling device:

First, a worker transports the aluminum ingot 23 onto the support surface 27 by a manual or mechanical transfer device. The aluminium ingot 23 is guided by the stop wall around the support surface 27 until the aluminium ingot 23 is positioned above the sampling slot 28 and the positioning assembly 6. Then, the positioning assembly 6 drives the positioning block 9 and the hydraulic telescopic rod 7 to ascend into the positioning cavity 24 of the aluminum crystallization ingot 23 through the lifting column 8. The hydraulic telescopic rod 7 is then extended and the positioning block 9 is moved outwards to abut against the inner side wall of the aluminium ingot 23, thereby clamping the ingot. The cutting assembly 4 starts to operate, and the circular saw cutter 19 moves horizontally forward under the action of the pushing unit 21 to saw the aluminum ingot 23 horizontally to form a horizontal cut surface. After the aluminum ingot 23 is partially cut by the circular saw cutter 19 of the cutting unit 4, the ingot is withdrawn, and the cutting operation is completed.

Then, as shown in fig. 5, the hydraulic rod 15 of the drilling assembly 5 pushes the slide 11 to move to the first sampling point a, and the sampling drill 13 is started. The lifting unit drives the lifting base 17 to move upwards through the lead screw 16 and the guide rod 12 to sample the position A. The sampling depth is 40mm (i.e. the target pushing distance) and the sampling drill 13 is pushed up by 10mm during the drilling process, and then a tool retracting operation is performed. After the sampling at the a position is completed, the control unit controls the sampling drill 13 to descend to the lowest position. Then, the slide 11 in the drilling assembly 5 drives the sampling drill 13 to move to the second sampling point B. The sampling drill 13 moves upward to sample the position B and drill to 40 mm. After the sampling of the B position is completed, the sampling drill bit 13 descends to the lowest point, and the slide block 11 drives the sampling drill bit 13 to return to the initial position, and the sampling process is finished. When A, B sawing of the sample 25 is completed, the ejector rod 18 in the sampling drill bit 13 can push out the sample 25 in the sampling drill bit 13 when the lifting base 17 descends, so that the sampling drill bit falls down by itself. In addition, aluminum chips generated during the cutting process of the cutting assembly 4 can fall onto the aluminum chip conveyor belt 3 through the chip discharge port 2. Aluminium scraps can be conveyed to the recovery place through the aluminium scraps conveyer belt 3, so that the aluminium scraps are convenient to clean. The whole process is simple, and the sampling is convenient.

In summary, the high-purity aluminum crystallization ingot sampling device has the following advantages:

1. The sampling device guides the aluminum crystallization ingot 23 through the U-shaped supporting surface 27 and the stop wall, so that the positioning cavity 24 of the aluminum crystallization ingot 23 is positioned above the positioning assembly 6, the positioning accuracy of the sampling position can be improved, and then the aluminum ingot is positioned through the positioning assembly 6, so that the aluminum crystallization ingot is prevented from shaking in the sampling process;

2. The sampling device can realize the effect of high-efficiency sampling by matching the cutting assembly 4 with the drilling assembly 5;

3. According to the sampling device, the ejector rod 18 is arranged in the sampling drill bit 13, and when the sampling drill bit 13 descends to a lower position, the ejector rod 18 can push out a sample 25 in the sampling drill bit 13, so that the sampling efficiency is further improved;

4. The sampling device also controls the sampling drill bit 13 to retract once when the sampling drill bit is pushed for a retracting distance through the control unit, so that the problems that the hollow drill is easy to be blocked in the drilling process and aluminum scraps are difficult to remove are solved.
