Description

Technical Field

[0001] This utility model relates to the field of aluminum rod take-up technology, and in particular to an automatic cutting device for aluminum rod take-up in rolling mills. Background Technology

[0002] After passing through a casting machine, rough rolling, finish rolling, and cooling, molten aluminum forms aluminum rods with a diameter of approximately 10mm. These rods are then collected into a wire basket by a take-up machine. When the aluminum rods in the take-up basket reach a certain height, they are cut off, and an empty take-up basket is placed directly below the take-up machine to begin the next take-up operation.

[0003] During the aluminum rod take-up process, the aluminum rod is usually sheared without stopping the production line. Because the aluminum rod itself is in continuous motion, and there is a speed difference between the cutter and the aluminum rod when performing the shearing action, the instantaneous force on the aluminum rod is uneven, which causes the aluminum rod cut to be skewed, deformed, and burr-like, making it difficult to improve the cutting quality of the aluminum rod. Utility Model Content

[0004] To improve the quality of aluminum rod take-up and cutting, this application provides an automatic cutting device for aluminum rod take-up in rolling mills.

[0005] The automatic cutting device for aluminum rod take-up in a rolling mill provided in this application adopts the following technical solution: An automatic cutting device for aluminum rod take-up in a rolling mill includes a wire feeding bracket, a wire feeding pipe extending through the wire feeding bracket, a wire basket assembly below the wire feeding pipe for collecting aluminum rods, a rodless cylinder fixedly mounted on the wire feeding bracket, a lifting bracket fixedly mounted on the output end of the rodless cylinder, a pneumatic-hydraulic booster cylinder fixedly mounted on the lifting bracket, a moving blade body fixedly mounted on the output end of the pneumatic-hydraulic booster cylinder, a stationary blade body mounted on the lifting bracket, and a guide assembly shared between the stationary blade body, the moving blade body, and the lifting bracket for guiding the aluminum rods between the stationary blade body and the moving blade body. Both the stationary blade body and the moving blade body are located above the wire basket assembly.

[0006] By adopting the above technical solution, during the aluminum rod take-up process, after the aluminum rod passes through the feeding tube, the guide assembly guides the aluminum rod between the stationary blade body and the moving blade body. After the aluminum rod passes through the stationary blade body and the moving blade body, it is collected by the wire basket assembly. When the aluminum rod is stacked to a certain height in the wire basket assembly, the output end of the rodless cylinder drives the lifting bracket to move synchronously with the aluminum rod, so that both the stationary blade body and the moving blade body move towards the wire basket assembly synchronously with the aluminum rod. At the same time, the output end of the pneumatic-hydraulic booster cylinder drives the moving blade body to move towards the stationary blade body, so that the moving blade body and the stationary blade body cooperate to cut the aluminum rod. This reduces the speed difference between the shearing action and the aluminum rod, and makes it easier for the aluminum rod to be subjected to uniform force at the moment of shearing. This makes it less likely for the aluminum rod cut to be skewed, deformed, or burr-like, thereby improving the quality of aluminum rod take-up and cutting.

[0007] Preferably, the guide assembly includes a positioning arm and a positioning block, both located above the wire basket assembly and below the wire feeding tube. One end of the positioning arm is connected to the lifting bracket, and the other end is fixedly connected to the positioning block. A positioning through hole is formed on the positioning block for inserting an aluminum rod. A moving blade slot is formed on one side of the positioning block, communicating with the positioning through hole for inserting a moving blade body. A stationary blade slot is formed on the other side of the positioning block, communicating with the positioning through hole. The stationary blade body passes through the stationary blade slot and is fixedly connected to the positioning block.

[0008] By adopting the above technical solution, after the aluminum rod passes through the wire feeding tube, the aluminum rod then passes through the positioning through hole. The positioning block guides the aluminum rod, allowing it to pass between the stationary knife body and the moving knife body.

[0009] Preferably, the guide assembly further includes a threading swing arm and a threading block, both located above the wire basket assembly and below the wire feeding tube. One end of the threading swing arm is connected to the lifting bracket, and the other end is fixedly connected to the threading block. A threading through hole is formed through the threading block, located above the positioning through hole. The threading through hole and the positioning through hole are coaxially arranged. The diameter of the end of the threading through hole away from the positioning through hole is larger than the diameter of the end of the threading through hole near the positioning through hole, and the diameter of the end of the threading through hole near the positioning through hole is larger than the diameter of the end of the positioning through hole near the threading through hole.

[0010] By adopting the above technical solution, after the aluminum rod passes through the wire feeding tube, the aluminum rod first passes through the wire through hole and then through the positioning through hole. The diameter of the holes is gradually narrowed through the wire through hole and the positioning through hole, which buffers and limits the high-speed moving aluminum rod, making it easier for the aluminum rod to run stably between the stationary knife body and the moving knife body.

[0011] Preferably, a laser ranging sensor is fixedly installed on the lifting bracket.

[0012] By adopting the above technical solution, the laser ranging sensor detects the stacking height of aluminum rods inside the wire basket assembly. When the aluminum rods are stacked to a certain height inside the wire basket assembly, the output ends of the rodless cylinder and the pneumatic-hydraulic booster cylinder both activate. After the output ends of the rodless cylinder and the pneumatic-hydraulic booster cylinder have both activated, they reset. After the output ends of the rodless cylinder and the pneumatic-hydraulic booster cylinder have both reset, the laser ranging sensor detects that the aluminum rods are stacked to a certain height inside the wire basket assembly, and the output ends of the rodless cylinder and the pneumatic-hydraulic booster cylinder activate again.

[0013] Preferably, the wire basket assembly includes a wire basket slide, a first wire basket, and a second wire basket. A wire basket slide groove is formed on the wire basket slide. The bottom ends of the first wire basket and the second wire basket are slidably disposed in the wire basket slide groove. The first wire basket and the second wire basket are both disposed below the laser rangefinder, the stationary blade body, and the moving blade body.

[0014] By adopting the above technical solution, when the aluminum rods are stacked to a certain height in the first wire basket, the aluminum rods are cut off, and the first and second wire baskets move so that the second wire basket moves below the aluminum rods. When the aluminum rods are stacked to a certain height in the second wire basket, the aluminum rods are cut off, and the first and second wire baskets move so that the first wire basket moves below the aluminum rods. The effect of switching between empty and full baskets is achieved by using the first and second wire baskets.

[0015] Preferably, a sliding frame is slidably arranged within the wire basket groove. The bottom ends of the first and second wire baskets are rotatably connected to the top of the sliding frame. A drive shaft and an auxiliary shaft are rotatably arranged on the sliding frame. Drive wheels are fixedly arranged at both ends of the drive shaft, and auxiliary wheels are fixedly arranged at both ends of the auxiliary shaft. The drive wheels and auxiliary wheels are rotatably arranged within the wire basket groove. A drive motor is fixedly arranged on the sliding frame. A drive pulley is fixedly arranged on the output shaft of the drive motor. A transmission pulley is sleeved on the drive shaft. The drive shaft and the transmission pulley are fixedly connected. A drive belt is sleeved on both the drive pulley and the transmission pulley.

[0016] By adopting the above technical solution, when the first wire basket and the second wire basket are moved, the drive motor starts and drives the drive pulley to rotate. The rotation of the drive pulley drives the transmission pulley to rotate through the drive belt. The rotation of the transmission pulley drives the drive shaft to rotate. The rotation of the drive shaft drives the drive wheel to rotate, thereby achieving the effect of the sliding frame moving within the wire basket groove, thus enabling the sliding frame to move the first wire basket and the second wire basket.

[0017] Preferably, a first rotating shaft is rotatably mounted on the sliding frame, the first rotating shaft is fixedly connected to the bottom of the first wire basket, a first driven pulley is sleeved on the first rotating shaft, the first rotating shaft and the first driven pulley are fixedly connected, a first motor is fixedly mounted on the sliding frame, a first driving pulley is fixedly mounted on the output shaft of the first motor, and the first driving pulley and the first driven pulley are together sleeved on a first belt.

[0018] By adopting the above technical solution, when the aluminum rod falls into the first wire basket, the first motor starts and drives the first drive pulley to rotate. The rotation of the first drive pulley drives the first driven pulley to rotate through the first belt. The rotation of the first driven pulley drives the first rotating shaft to rotate. The rotation of the first shaft drives the first wire basket to rotate, so that the aluminum rod is evenly collected in the first wire basket.

[0019] Preferably, a second rotating shaft is rotatably mounted on the sliding frame, the second rotating shaft is fixedly connected to the bottom of the second wire basket, a second driven pulley is sleeved on the second rotating shaft, the second rotating shaft and the second driven pulley are fixedly connected, a second motor is fixedly mounted on the sliding frame, a second driving pulley is fixedly mounted on the output shaft of the second motor, and the second driving pulley and the second driven pulley are together sleeved on a second belt.

[0020] By adopting the above technical solution, when the aluminum rod falls into the second wire basket, the second motor starts and drives the second drive pulley to rotate. The rotation of the second drive pulley drives the second driven pulley to rotate through the second belt. The rotation of the second driven pulley drives the second rotating shaft to rotate. The rotation of the second shaft drives the second wire basket to rotate, so that the aluminum rod is evenly collected in the second wire basket.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a wire feeding bracket, wire feeding pipe, wire basket assembly, rodless cylinder, lifting bracket, pneumatic-hydraulic booster cylinder, moving blade body, stationary blade body and guide assembly, the speed difference between the shearing action and the aluminum rod is reduced, which makes it easier for the aluminum rod to be subjected to uniform force at the moment of shearing, and makes the aluminum rod cut less likely to be skewed, deformed and burr-like, thus improving the quality of aluminum rod wire take-up and cutting. 2. By setting a positioning swing arm, positioning block, positioning through hole, moving knife slot and stationary knife slot, the positioning block guides the aluminum rod so that the aluminum rod passes between the stationary knife body and the moving knife body; 3. By setting up a wire basket slide, a first wire basket, a second wire basket, and a wire basket slide groove, the effect of switching between empty and full baskets can be achieved using the first and second wire baskets.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses an automatic cutting device for aluminum rod take-up in a rolling mill. (Refer to...) Figure 1 and Figure 2The assembly includes a wire feeding bracket 11, through which a wire feeding pipe 1 is installed, through which aluminum rods 8 protrude. A wire basket assembly 2 is mounted below the wire feeding pipe 1 to collect the aluminum rods 8. A rodless cylinder 3 is fixedly installed on the wire feeding bracket 11, and a lifting bracket 31 is fixedly installed on the output end of the rodless cylinder 3. A laser rangefinder sensor 34 is fixedly installed on the lifting bracket 31 to detect the stacking height of the aluminum rods 8 within the wire basket assembly 2. A pneumatic-hydraulic booster cylinder 321 is fixedly installed on the lifting bracket 31, and a moving blade body 32 is fixedly installed on the output end of the pneumatic-hydraulic booster cylinder 321. A stationary blade body 33 is installed on the lifting bracket 31, and the stationary blade body 33 is positioned opposite the moving blade body 32. Both the stationary blade body 33 and the moving blade body 32 are located above the wire basket assembly 2. A guide assembly 4 is provided between the stationary blade body 33, the moving blade body 32, and the lifting bracket 31 to guide the aluminum rods 8 between the stationary blade body 33 and the moving blade body 32. During the take-up process of aluminum rod 8, after passing through the wire feeding tube 1, the guide assembly 4 guides the aluminum rod 8 between the stationary blade body 33 and the moving blade body 32. After passing through the stationary blade body 33 and the moving blade body 32, the aluminum rod 8 is collected by the wire basket assembly 2. When the aluminum rod 8 is stacked to a certain height in the wire basket assembly 2, the output end of the rodless cylinder 3 drives the lifting bracket 31 to move synchronously with the aluminum rod 8, so that both the stationary blade body 33 and the moving blade body 32 move towards the wire basket assembly 2 synchronously with the aluminum rod 8. At the same time, the output end of the pneumatic-hydraulic booster cylinder 321 drives the moving blade body 32 to move towards the stationary blade body 33, so that the moving blade body 32 and the stationary blade body 33 cooperate to cut the aluminum rod 8. This reduces the speed difference between the shearing action and the aluminum rod 8, making it easier for the aluminum rod 8 to be subjected to uniform force at the moment of shearing. This makes it less likely for the cut of the aluminum rod 8 to be skewed, deformed, or burr-like, thereby improving the take-up and cutting quality of the aluminum rod 8. After both the output ends of the rodless cylinder 3 and the pneumatic-hydraulic booster cylinder 321 have completed their actions, they both reset. Once both have reset, when the laser rangefinder 34 detects that the aluminum rods 8 have stacked to a certain height within the wire basket assembly 2, the output ends of the rodless cylinder 3 and the pneumatic-hydraulic booster cylinder 321 activate again.

[0030] Reference Figures 1 to 3The guide assembly 4 includes a positioning swing arm 41, a positioning block 42, a wire threading swing arm 43, and a wire threading block 44. The positioning swing arm 41 and positioning block 42 are both located above the wire basket assembly 2, and the wire threading swing arm 43 and wire threading block 44 are both located above the positioning swing arm 41 and positioning block 42, and below the wire feeding pipe 1. One end of the positioning swing arm 41 and one end of the wire threading swing arm 43 are connected to the lifting bracket 31, and the other end of the positioning swing arm 41 is fixedly connected to the positioning block 42, and the other end of the wire threading swing arm 43 is fixedly connected to the wire threading block 44. A positioning through hole 421 is formed through the positioning block 42, and a wire threading through hole 441 is formed through the wire threading block 44. Both the positioning through hole 421 and the wire threading through hole 441 are for inserting aluminum rods 8. The wire threading through hole 441 is located above the positioning through hole 421 and is coaxially arranged with the positioning through hole 421. The diameter of the end of the through hole 441 furthest from the positioning through hole 421 is larger than the diameter of the end of the through hole 441 closest to the positioning through hole 421, and vice versa. A movable blade slot 422 is provided on one side of the positioning block 42, communicating with the positioning through hole 421, and the movable blade body 32 is inserted into the slot. A stationary blade slot 423 is provided on the other side of the positioning block 42, communicating with the positioning through hole 421, and the stationary blade body 33 passes through the stationary blade slot 423 and is fixedly mounted on the positioning block 42. After the aluminum rod 8 passes through the wire feed tube 1, it first exits through the through hole 441, then passes through the positioning through hole 421, allowing the aluminum rod 8 to pass between the stationary blade body 33 and the movable blade body 32. By gradually narrowing the aperture through the through hole 441 and the positioning through hole 421, the high-speed moving aluminum rod 8 is buffered and limited, which facilitates the stable operation of the aluminum rod 8 between the stationary knife body 33 and the moving knife body 32.

[0031] Reference Figures 1 to 5 The wire basket assembly 2 includes a wire basket slide 21, a first wire basket 22, and a second wire basket 23. A wire basket slide groove 211 is formed on the wire basket slide 211, and a sliding frame 5 is slidably disposed within the wire basket slide groove 211. The bottom ends of both the first wire basket 22 and the second wire basket 23 are rotatably connected to the top of the sliding frame 5. Both the first wire basket 22 and the second wire basket 23 are positioned below the laser rangefinder sensor 34, the stationary blade body 33, and the moving blade body 32. When the aluminum rod 8 is stacked to a certain height within the first wire basket 22, the aluminum rod 8 is cut off, and the first wire basket 22 and the second wire basket 23 move, causing the second wire basket 23 to move below the aluminum rod 8. The first wire basket 22 and the second wire basket 23 achieve the effect of switching between empty and full baskets.

[0032] Reference Figures 1 to 5A drive shaft 511 and an auxiliary shaft 521 are rotatably mounted on the sliding frame 5, and the drive shaft 511 and auxiliary shaft 521 are arranged in parallel. Drive wheels 51 are fixedly mounted at both ends of the drive shaft 511, and auxiliary wheels 52 are fixedly mounted at both ends of the auxiliary shaft 521. Both drive wheels 51 and auxiliary wheels 52 are rolled within the basket groove 211. A drive motor 53 is fixedly mounted on the sliding frame 5, and a drive pulley 531 is fixedly mounted on the output shaft of the drive motor 53. A transmission pulley 532 is sleeved on the drive shaft 511, and the drive shaft 511 and transmission pulley 532 are fixedly connected. A drive belt 533 is sleeved on both the drive pulley 531 and the transmission pulley 532. When the first wire basket 22 and the second wire basket 23 are moved, the drive motor 53 starts and drives the drive pulley 531 to rotate. The rotation of the drive pulley 531 drives the transmission pulley 532 to rotate through the drive belt 533. The rotation of the transmission pulley 532 drives the drive shaft 511 to rotate. The rotation of the drive shaft 511 drives the drive wheel to rotate, thereby realizing the effect of the sliding frame 5 moving within the wire basket groove 211, thus causing the sliding frame 5 to drive the first wire basket 22 and the second wire basket 23 to move.

[0033] Reference Figure 4 and Figure 5 A first rotating shaft 221 is rotatably mounted on the sliding frame 5, and the first rotating shaft 221 is fixedly connected to the bottom of the first wire basket 22. A first driven pulley 62 is sleeved on the first rotating shaft 221, and the first rotating shaft 221 and the first driven pulley 62 are fixedly connected. A first motor 6 is fixedly mounted on the sliding frame 5, and a first driving pulley 61 is fixedly mounted on the output shaft of the first motor 6. The first driving pulley 61 and the first driven pulley 62 are together sleeved on a first belt 63. When the aluminum rod 8 falls into the first wire basket 22, the first motor 6 starts and drives the first driving pulley 61 to rotate. The rotation of the first driving pulley 61 drives the first driven pulley 62 to rotate through the first belt 63. The rotation of the first driven pulley 62 drives the first rotating shaft 221 to rotate. The rotation of the first rotating shaft 221 drives the first wire basket 22 to rotate, so that the aluminum rod 8 is evenly collected in the first wire basket 22.

[0034] Reference Figure 4 and Figure 5A second rotating shaft 231 is rotatably mounted on the sliding frame 5, and the second rotating shaft 231 is fixedly connected to the bottom of the second wire basket 23. A second driven pulley 72 is sleeved on the second rotating shaft 231, and the second rotating shaft 231 and the second driven pulley 72 are fixedly connected. A second motor 7 is fixedly mounted on the sliding frame 5, and a second driving pulley 71 is fixedly mounted on the output shaft of the second motor 7. The second driving pulley 71 and the second driven pulley 72 are together sleeved on a second belt 73. When the aluminum rod 8 falls into the second wire basket 23, the second motor 7 starts and drives the second driving pulley 71 to rotate. The rotation of the second driving pulley 71 drives the second driven pulley 72 to rotate through the second belt 73. The rotation of the second driven pulley 72 drives the second rotating shaft 231 to rotate. The rotation of the second rotating shaft 231 drives the second wire basket 23 to rotate, so that the aluminum rod 8 is evenly collected in the second wire basket 23.

[0035] The implementation principle of the automatic cutting device for taking in aluminum rod 8 in this embodiment of the application is as follows: During the taking in process of aluminum rod 8, after passing through the wire feeding pipe 1, aluminum rod 8 first passes through the wire passing through hole 441, and then passes through the positioning through hole 421, so that aluminum rod 8 passes between the stationary knife body 33 and the moving knife body 32. After the aluminum rod 8 passes through the stationary knife body 33 and the moving knife body 32, it is collected through the first wire basket 22 or the second wire basket 23. When the aluminum rods 8 are stacked to a certain height in the first wire basket 22 or the second wire basket 23, the output end of the rodless cylinder 3 drives the lifting bracket 31 to move synchronously with the aluminum rods 8. This causes both the stationary blade body 33 and the moving blade body 32 to move closer to the wire basket assembly 2 simultaneously with the aluminum rods 8. At the same time, the output end of the pneumatic-hydraulic booster cylinder 321 drives the moving blade body 32 to move closer to the stationary blade body 33. This allows the moving blade body 32 and the stationary blade body 33 to work together to cut the aluminum rods 8, reducing the speed difference between the shearing action and the aluminum rods 8. This ensures that the aluminum rods 8 are subjected to uniform force during the shearing process, making it less likely for the cut of the aluminum rods 8 to be skewed, deformed, or burr-like, thus improving the quality of the aluminum rods 8's take-up and cutting. After both the output ends of the rodless cylinder 3 and the pneumatic-hydraulic booster cylinder 321 have completed their actions, they both return to their original positions. After the output ends of the rodless cylinder 3 and the pneumatic-hydraulic booster cylinder 321 are both reset, the laser rangefinder 34 detects that the aluminum rod 8 has been stacked to a certain height in the wire basket assembly 2, and the output ends of the rodless cylinder 3 and the pneumatic-hydraulic booster cylinder 321 are activated again.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
