Abstract
Description
Technical Field
[0001] This invention relates to the field of cold bending processing technology, and in particular to a device and method for cold bending and shaping bamboo strips. Background Technology
[0002] Cold bending is a highly efficient metal plastic forming process that uses multiple, sequentially arranged forming rollers to progressively and continuously bend metal strips to obtain the desired complex cross-sectional shape. It is widely used in the manufacturing of products such as building steel structures, automotive parts, furniture, and warehouse racking.
[0003] Traditional cold bending and shaping equipment typically includes a frame, a drive system, and multiple forming frames arranged sequentially along the production line. Each forming frame is equipped with one or more pairs of horizontal or vertical forming rollers, with holes on the rollers that match the local shape of the target profile cross-section. Under the clamping and guidance of the rollers, the strip passes through each set of rollers in sequence, and its cross-sectional shape is gradually bent and shaped.
[0004] However, ordinary bamboo strip curved surface cold bending and shaping devices and methods usually have some problems in daily use. With the development of technology, technicians in related fields have also made a lot of optimizations to bamboo strip curved surface cold bending and shaping devices and methods to solve some of the problems that different consumer groups care about. In order to make a more accurate comparison, Chinese patent with publication number CN220329674U discloses an aluminum profile cold bending device, including a main body of the equipment and a cold bending part. A limit box is set on the top of one end of the main body of the equipment, a limit frame is set on one end of the limit box, and protruding side plates are set on both sides of one end of the limit box. The limit frame is equipped with limit rollers of different diameters inside. After the aluminum profile is placed inside the limiting box, the pressure plate is pressed down by the electric telescopic rod to hold the aluminum profile against it. Then, the clamping plate and blocking pad are used to limit the two sides of the aluminum profile. In this way, one end of the aluminum profile can be limited during cold bending, so that one end is fixed while the other end rotates. This can effectively prevent both ends from shrinking inward at the same time, ensuring the accuracy of the processing position, and also preventing the end position from swinging, thus ensuring the production quality of the product and improving the use effect.
[0005] However, the above-mentioned aluminum profile cold bending device still has some shortcomings in actual use:
[0006] 1. The above-mentioned aluminum profile cold bending device can place the aluminum profile inside the limiting box and then press down the pressure plate with the electric telescopic rod to make it hold the aluminum profile. Then, the clamping plate and blocking pad are used to limit the two sides of the aluminum profile. However, when clamping the material, it cannot change with the width of the material. It can only process materials of a specific width.
[0007] 2. The above-mentioned aluminum profile cold bending device uses an electric screw to drive the limiting frame and limiting rollers to different working heights via a spiral sleeve, so that the upper ends of the limiting rollers of different diameters are flush with the transmission mechanism inside the limiting box. However, it cannot fix the material well during processing, which causes the material to vibrate during processing.

[0038] The following is in conjunction with the appendix Figures 1 to 10 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.
[0039] This application discloses a cold bending and shaping device and method for bamboo strip curved surfaces. It is explained that this application is mainly used in the process of pressing aluminum material into bamboo strip curved surfaces. Technically, it can center aluminum materials of different sizes and specifications, thereby improving the practicality of the device. In particular, it can fix the aluminum material during processing to prevent vibration and thus prevent affecting the processing quality. Furthermore, this application can also cut the aluminum material into equal segments after processing, facilitating storage and transportation by operators.
[0040] Example 1:
[0041] Reference Figure 1As shown, a cold bending and shaping device for curved bamboo strips includes a mounting plate 1, a support plate 10, a rotating shaft 11, a roller 12, a baffle 13, an H-shaped frame 14, a rotating shaft 15, an upper roller 16, a lower roller 17, a centering mechanism 2, and a stabilizing mechanism 3. Support plates 10 are symmetrically arranged on the top of one side of the mounting plate 1. A rotating shaft 11 is arranged between the support plates 10, and a roller 12 is sleeved on the rotating shaft 11. Aluminum material can be wound around the roller 12 for storage. The roller 12 can rotate under the constraint of the rotating shaft 11. Baffles 13 are symmetrically arranged on the outer wall of the roller 12 to prevent the aluminum material from detaching from the roller 12. An H-shaped frame 14 is also arranged on the top of the mounting plate 1. Multiple rotating shafts 15 are rotatably arranged between the inner walls of the top of the H-shaped frame 14, and the rotating shafts 15 can rotate under the constraint of the H-shaped frame 14. A roller 12 is sleeved on the rotating shaft 15. The machine is equipped with upper rollers 16 of different specifications. When the rotating shaft 15 rotates, it can drive the upper rollers 16 to rotate together. A lower roller 17 that cooperates with the upper rollers 16 is rotatably arranged between the top inner walls of the H-shaped frame 14. When the aluminum material passes between the upper rollers 16 and the lower rollers 17, the shape of the aluminum material gradually changes according to the shape of the upper rollers 16 and the lower rollers 17. A centering mechanism 2 is provided on the outer wall of the H-shaped frame 14 near the roller 12. The centering mechanism 2 is used to center the aluminum materials of different sizes and specifications, and can also determine the height of the aluminum material entering the device, thereby improving the practicality of the device. A stabilizing mechanism 3 is provided inside the H-shaped frame 14 and on both sides of the rotating shaft 15. The stabilizing mechanism 3 is used to fix the aluminum material during the processing of the aluminum material, prevent the aluminum material from vibrating during the processing, and thus prevent it from affecting the processing quality of the aluminum material.
[0042] In the specific implementation process, the operator winds the aluminum material around the roller 12. The aluminum material of different sizes is centered by the centering mechanism 2, thereby improving the practicality of the device. Then the aluminum material passes between the upper roller 16 and the lower roller 17. The stabilizing mechanism 3 drives the rotating shaft 15 to rotate. When the rotating shaft 15 rotates, it drives the upper roller 16 to rotate together, so that the aluminum material passes between multiple upper rollers 16 and lower rollers 17. Finally, the shape of the aluminum material is gradually changed according to the shape of the upper roller 16 and the lower roller 17. During this process, the aluminum material can be fixed to prevent vibration during processing, thereby preventing the processing quality of the aluminum material from being affected.
[0043] Reference Figure 2As shown, this is the centering mechanism 2 in this application; specifically, the centering mechanism 2 includes an arc-shaped lower plate 20, a fixed rod 200, a lower rotating roller 201, an arc-shaped upper plate 202, a moving rod 203, an upper rotating roller 204, a fixed plate 205, and a spring 206. The outer wall of the H-shaped frame 14 is symmetrically provided with arc-shaped lower plates 20, and a fixed rod 200 is arranged between the arc-shaped lower plates 20. The lower rotating roller 201 is rotatably sleeved on the fixed rod 200, and the lower rotating roller 201 can rotate under the restriction of the fixed rod 200. The outer wall of the H-shaped frame 14 is symmetrically rotatably provided with arc-shaped lower plates 20. The upper plate 202, which is arc-shaped, can rotate under the constraint of the H-shaped frame 14. A moving rod 203 is provided between the arc-shaped upper plates 202, which can drive the moving rod 203 to rotate together when the arc-shaped upper plate 202 rotates. An upper rotating roller 204 is rotatably sleeved on the moving rod 203, which can rotate under the constraint of the moving rod 203. A fixed plate 205 is provided on the outer wall of the H-shaped frame 14, and a spring 206 is provided between the arc-shaped upper plate 202 and the fixed plate 205. The spring 206 can always provide a downward pulling force to the arc-shaped upper plate 202.
[0044] In the specific implementation process, the bottom of the aluminum material wound on the roller 12 abuts against the lower rotating roller 201, thereby limiting the height of the aluminum material entering the H-shaped frame 14. Then, the arc-shaped upper plate 202 rotates downward under the action of the spring 206. When the arc-shaped upper plate 202 rotates, it can drive the moving rod 203 to rotate together. When the moving rod 203 rotates, it can drive the upper rotating roller 204 to rotate together, so that the upper rotating roller 204 abuts against the top of the aluminum material, thereby ensuring that the bottom surface of aluminum materials of different thicknesses is at the same horizontal plane when entering the H-shaped frame 14.
[0045] Reference Figure 3 and Figure 4As shown, this is the centering mechanism 2 in this application; specifically, the centering mechanism 2 also includes a rotating plate 21, a central column 210, a centering ring 211, a threaded rod 212, a rotating ring 213, a slider 214, an adjusting plate 215, a synchronizing plate 216, a strip plate 217, an inclined plate 218, and a contact rod 219. The rotating plate 21 is rotatably mounted on the inner wall of the top of the H-shaped frame 14, and the rotating plate 21 can rotate under the restriction of the H-shaped frame 14; the central column 210 is mounted on the top of the rotating plate 21, and the rotating plate 21 can drive the central column 210 together when it rotates. Rotation; a central ring 211 is rotatably sleeved on the central column 210, and the central ring 211 can rotate under the restriction of the central column 210; a threaded rod 212 is provided inside the central column 210 through threaded engagement, and the height of the threaded rod 212 can be adjusted by rotating the threaded rod 212; a rotating ring 213 is sleeved on the threaded rod 212 through bearing engagement, and when the height of the threaded rod 212 is adjusted by rotation, it can drive the rotating ring 213 to move together; sliders 214 are symmetrically slidably arranged on the inner wall of the H-shaped frame 14, and the sliders 214 can be limited by the H-shaped frame 14. The slider 214 is hinged to the center column 210 and an adjusting plate 215 is provided. When the slider 214 moves, it can drive the adjusting plate 215 to move together, so that the adjusting plate 215 can rotate under the restriction of the center column 210, thereby changing the distance between the center column 210 and the slider 214. The top of the slider 214 passes through the H-shaped frame 14 and is connected by a synchronous plate 216. When the synchronous plate 216 moves, it can drive the slider 214 connected to it to move together. A strip plate is provided on the side of the slider 214 away from the centering ring 211, passing through the H-shaped frame 14. 217. When the slider 214 moves, it can drive the strip plate 217 to move together. A sloping plate 218 is provided on the side of the strip plate 217 away from the slider 214. When the strip plate 217 moves, it can drive the sloping plate 218 to move together. A contact rod 219 is provided on the side of the sloping plate 218 near the arc-shaped upper plate 202, which abuts against its bottom. When the sloping plate 218 moves, it can drive the contact rod 219 to move together. When the contact rod 219 moves, it can drive the arc-shaped upper plate 202 to rotate, so that the tilt angle of the arc-shaped upper plate 202 can be adjusted when the position of the slider 214 is adjusted.
[0046] In the specific implementation process, when the aluminum material passes through the upper rotating roller 204 and the lower rotating roller 201 and enters the H-shaped frame 14, the bottom surface of the aluminum material abuts against the central ring 211, and the side of the aluminum material abuts against the central column 210. Then, according to the thickness of the aluminum material, the threaded rod 212 is rotated to move up and down. When the threaded rod 212 moves up and down, it can drive the rotating ring 213 to move together, so that the top of the aluminum material abuts against the bottom of the rotating ring 213, thereby determining the position of the aluminum material entering the H-shaped frame 14, which is convenient for the next step of processing.
[0047] To ensure that the bottom of the aluminum material abuts against the centering ring 211 and the side of the aluminum material abuts against the center column 210, the operator adjusts the position of the synchronization plate 216 according to the width of the aluminum material. When the synchronization plate 216 moves, it drives the slider 214 connected to it to move together. When the slider 214 moves, it drives the adjustment plate 215 to move together, so that the adjustment plate 215 rotates under the restriction of the center column 210. When the center column 210 moves, it drives the rotating plate 21 to rotate, thereby changing the distance between the center column 210 and the slider 214. After the distance between the center column 210 and the slider 214 changes, it will drive the centering ring 211 and the rotating ring 213 to move together, centering aluminum materials of different sizes and specifications, thereby improving the practicality of the device.
[0048] Reference Figure 5 and Figure 6 As shown, this is the stabilizing mechanism 3 in this application. Specifically, the stabilizing mechanism 3 includes a square groove 30, a gear ring 31, a locking block 32, a locking groove 33, and a second spring 34. The top inner wall of the H-shaped frame 14 is provided with a square groove 30 for the rotating shaft 15 to slide. The rotating shaft 15 can slide up and down under the restriction of the square groove 30. When the rotating shaft 15 moves, it can drive the upper roller 16 to move together. A gear ring 31 is fitted on the rotating shaft 15 and inside the H-shaped frame 14. A locking block 32 is provided on the side of the gear ring 31 near the rotating shaft 15. A locking groove 33 is provided on the rotating shaft 15 at the bottom of the locking block 32. When the gear ring 31 drives the locking block 32 into the locking groove 33, the rotation of the gear ring 31 can drive the rotating shaft 15 to rotate together. A second spring 34 is provided between the locking groove 33 and the locking block 32. The second spring 34 can always provide an upward thrust to the locking block 32 and the gear ring 31.
[0049] In the specific implementation process, when the gear ring 31 drives the locking block 32 into the locking slot 33, the rotation of the gear ring 31 can drive the rotating shaft 15 to rotate together.
[0050] Reference Figure 7As shown, this is the stabilizing mechanism 3 in this application; specifically, the stabilizing mechanism 3 also includes a chamfered rod 35, a spur gear 36, a reset plate 37, a spring 38, and a drive unit 39. The chamfered rod 35 is rotatably mounted on the side of the rotating shaft 15 away from the upper roller 16, and when the rotating shaft 15 moves, it can drive the chamfered rod 35 to move together; a spur gear 36 that mates with the gear ring 31 is rotatably sleeved on the other side of the chamfered rod 35, and when the chamfered rod 35 moves, it can drive the spur gear 36 to move together, and when the spur gear 36 rotates, it can drive the spur gear 39. The moving gear ring 31 rotates; a reset plate 37 that abuts against the rotating shaft 15 is slidably disposed in the square groove 30, and a spring 38 is disposed between the reset plate 37 and the square groove 30. The spring 38 can always provide an upward thrust to the reset plate 37. When the reset plate 37 moves, it can drive the rotating shaft 15 to move together; a drive unit 39 is also disposed in the H-shaped frame 14. The drive unit 39 is used to drive the spur gear 36 to rotate and push the upper roller 16 to move downward, so that the upper roller 16 is in close contact with the aluminum material.
[0051] In the specific implementation process, the drive unit 39 pushes the upper roller 16 to move downward, so that the upper roller 16 is in close contact with the aluminum material. During this process, the drive unit 39 will also drive the spur gear 36 to rotate. During the downward movement of the upper roller, the locking block 32 does not enter the locking groove 33. When the spur gear 36 rotates, it will push the gear ring 31 to shake, but will not drive the gear ring 31 to rotate.
[0052] When the drive unit 39 drives the upper roller 16 to come into contact with the aluminum material, the upper roller 16 moves and drives the rotating shaft 15 to move together. The rotating shaft 15 moves and drives the shaped rod 35 to move together. The shaped rod 35 moves and drives the spur gear 36 to move together. The spur gear 36 rotates and drives the gear ring 31 to rotate. The gear ring 31 rotates and drives the rotating shaft 15 to rotate together. The rotating shaft 15 rotates and drives the upper roller 16 to rotate together.
[0053] Reference Figure 8As shown, this is the drive unit 39 in this application; specifically, the drive unit 39 includes a drive shaft 390, a drive motor 391, a gear chain 392, a transmission rod 393, a contact ring 394, and an arc-shaped triangular block 395. A drive shaft 390 is rotatably mounted inside the H-shaped frame 14 on the side away from the upper roller 16. A drive motor 391, connected to one pair of drive shafts 390, is mounted on the outer wall of the H-shaped frame 14 through a motor housing. When the drive motor 391 rotates, it can drive the drive shafts 390 to rotate together. Multiple drive shafts 390 are connected by belt drive, and the rotation of one pair of drive shafts 390 can drive multiple drive shafts 390 to rotate together via belt drive. The drive unit 390 is located inside the H-shaped frame 14 and is positioned relative to the drive shaft 390. A toothed chain 392 is provided on one side, and the drive shaft 390 can drive the toothed chain 392 to rotate together when it rotates. A transmission rod 393 is rotatably arranged inside the H-shaped frame 14. An abutment ring 394 is sleeved on the transmission rod 393 and located above the toothed ring 31. An arc-shaped triangular block 395 is provided on the outer wall of the abutment ring 394. When the transmission rod 393 rotates, it can drive the abutment ring 394 to rotate together. When the abutment ring 394 rotates, it can drive the arc-shaped triangular block 395 to rotate together. When the arc-shaped triangular block 395 rotates, it will push the toothed ring 31 to move downward, so that the locking block 32 enters the locking groove 33. The transmission rod 393 and the drive shaft 390 are connected by belt drive. When the drive shaft 390 rotates, it can drive the transmission rod 393 to rotate together.
[0054] In the specific implementation process, when the drive motor 391 rotates, it can drive the drive shaft 390 to rotate together. The rotation of one pair of drive shafts 390 can drive multiple drive shafts 390 to rotate together through belt transmission. When the drive shaft 390 rotates, it can drive the transmission rod 393 to rotate together. The rotation of the transmission rod 393 can drive the contact ring 394 to rotate together. The rotation of the contact ring 394 can drive the arc-shaped triangular block 395 to rotate together. When the arc-shaped triangular block 395 abuts against the gear ring 31, the rotation of the arc-shaped triangular block 395 will push the gear ring 31 to move downward. The gear ring 31 pushes the rotating shaft 15 and the upper rolling roller to move together, so that the upper rolling roller 16 is in close contact with the top of the aluminum material. At this time, the upper rolling roller 16 and the rotating shaft 15 no longer move, so that the locking block 32 enters the locking groove 33. At the same time, when the drive shaft 390 rotates, it can drive the gear chain 392 to rotate together. The rotation of the gear chain 392 can drive the spur gear 36 to rotate together.

[0056] Reference Figure 9As shown, based on Embodiment 1, to facilitate the storage and transportation of processed aluminum materials by operators, in this specific embodiment, a cutting mechanism 4 is provided at the top of the H-shaped frame 14. Specifically, the cutting mechanism 4 includes a T-shaped block 40, a square block 41, a limiting groove 42, a reciprocating lead screw 43, and a connecting rod 430. The T-shaped block 40 is symmetrically slidably arranged at the top of the H-shaped frame 14, and the square block 41 is provided on the top of the T-shaped block 40. The square block 41 can slide under the restriction of the T-shaped block 40, and the T-shaped block 40 can be restricted by the H-shaped frame 14. The square block 41 is provided with a limiting groove 42, through which the processed aluminum material can pass through the square block 41. The H-shaped frame 14 is provided with a reciprocating lead screw 43, and a connecting rod 430 connected to the square block 41 is sleeved on the reciprocating lead screw 43. The reciprocating lead screw 43 and the drive shaft 390 are connected by belt drive. When the drive shaft 390 rotates, it can drive the reciprocating lead screw 43 to rotate together. When the reciprocating lead screw 43 rotates, it can drive the connecting rod 430 to move back and forth. When the connecting rod 430 moves back and forth, it can drive the square block 41 to move together.
[0057] In the specific implementation process, when the drive shaft 390 rotates, it can drive the reciprocating lead screw 43 to rotate together. When the reciprocating lead screw 43 rotates, it can drive the connecting rod 430 to move back and forth. When the connecting rod 430 moves back and forth, it can drive the square block 41 to move together. The square block 41 can slide under the restriction of the T-shaped block 40. The T-shaped block 40 can slide under the restriction of the H-shaped frame 14. The processed aluminum material can pass through the square block 41 through the limiting groove 42.
[0058] Reference Figure 10As shown, this is the cutting mechanism 4 in this application; specifically, the cutting mechanism 4 also includes a vertical plate 44, a cutting block 45, a take-up shaft 46, a take-up ring 460, a steel cable 461, an arc-shaped triangular tooth 462, a limiting block 47, a rack 48, and a spring 49. The vertical plate 44 is symmetrically arranged on the top of the square block 41, and when the square block 41 moves, it can drive the vertical plate 44 to move together. The cutting block 45 is slidably arranged between the vertical plates 44, and can slide under the restriction of the vertical plate 44. The cutting block 45 is used to cut the processed aluminum material. The take-up shaft 46 is rotatably arranged on the side of the square block 41 near the reciprocating lead screw 43, and when the square block 41 moves, it can drive the take-up shaft 46 to move together. A take-up ring 460 is sleeved on the take-up shaft 46, and when the take-up ring 460 rotates, it can drive the take-up shaft 46 to move within the square block 41. The cutting block 45 is restricted from rotating; a steel cable 461 is provided on the top of the cutting block 45 and wound on the take-up ring 460. When the take-up ring 460 rotates, it can drive the steel cable 461 to move. When the steel cable 461 moves, it can drive the cutting block 45 to move up and down. Multiple arc-shaped triangular teeth 462 are arranged around the take-up ring 460. A limit block 47 is provided on the inner wall of the H-shaped frame 14. A rack 48 that cooperates with the arc-shaped triangular teeth 462 is slidably arranged in the limit block 47. The rack 48 can slide under the restriction of the limit block 47. When the take-up ring 460 moves, it can drive the arc-shaped triangular teeth 462 to move together. When the arc-shaped triangular teeth 462 abut against the rack 48, it can drive the take-up ring 460 to rotate. Multiple springs 49 are connected between the limit block 47 and the rack 48. The springs 49 can always provide an upward thrust to the rack 48.
[0059] One point to note is that the arc-shaped triangular teeth 462 are not evenly distributed around the circumference of the take-up ring 460, but are left with gaps. This means that when the take-up ring 460 rotates to the gap position under the drive of the rack 48, the arc-shaped triangular teeth 462 are no longer restricted by the rack 48, causing the cutting block 45 to move downward under the action of gravity, and causing the take-up ring 460 to reset.
[0060] In the specific implementation process, after the processed aluminum material passes through the limiting groove 42 and the square block 41 for a certain distance, the drive shaft 390 rotates, which drives the reciprocating screw 43 to rotate together. When the reciprocating screw 43 rotates, it drives the connecting rod 430 to move back and forth. When the connecting rod 430 moves back and forth, it drives the square block 41 to move together. When the square block 41 moves, it drives the take-up shaft 46 and the take-up ring 460 to move together. When the take-up ring 460 moves, it drives the arc-shaped triangular tooth 462 to move together. When the arc-shaped triangular tooth 462 moves... When the take-up ring 460 contacts the rack 48, it drives the take-up ring 460 to rotate. The rotation of the take-up ring 460 drives the take-up shaft 46 to rotate as well. The rotation of the take-up shaft 46 winds the steel cable 461 around it. As the steel cable 461 winds around, it drives the cutting block 45 to move upwards under the constraint of the vertical plate 44. When the take-up ring 460 rotates to the empty position under the drive of the rack 48, the arc-shaped triangular tooth 462 is no longer constrained by the rack 48, causing the cutting block 45 to move downwards under gravity, thus cutting the processed aluminum material.
[0061] The take-up shaft 46 and take-up ring 460 are reset via the steel cable 461. After the aluminum material is cut, the reciprocating screw 43 drives the square block 41 to reset. When the square block 41 resets, it drives the take-up shaft 46 and take-up ring 460 to reset together. This causes the arc-shaped triangular teeth 462 to press the rack 48, which is then driven to slide downward under the restriction of the limit block 47, so that the take-up shaft 46 and take-up ring 460 will not rotate.
[0062] In addition, the present invention also provides a method for cold bending and shaping of curved bamboo strips, comprising the following steps:
[0063] Step 1: The operator winds aluminum material onto roller 12. The bottom of the aluminum material wound on roller 12 abuts against the lower rotating roller 201, thereby limiting the height of the aluminum material entering the H-shaped frame 14. Then, the arc-shaped upper plate 202 rotates downward under the pull of spring 206. When the arc-shaped upper plate 202 rotates, it can drive the moving rod 203 to rotate together. When the moving rod 203 rotates, it can drive the upper rotating roller 204 to rotate together, so that the upper rotating roller 204 abuts against the top of the aluminum material, thereby ensuring that the bottom surface of aluminum materials of different thicknesses is at the same level when entering the H-shaped frame 14.
[0064] Step 2: When the aluminum material passes through the upper rotating roller 204 and the lower rotating roller 201 and enters the H-shaped frame 14, the bottom surface of the aluminum material abuts against the central ring 211, and the side of the aluminum material abuts against the central column 210. Then, according to the thickness of the aluminum material, the threaded rod 212 is rotated to move up and down. When the threaded rod 212 moves up and down, it can drive the rotating ring 213 to move together, so that the top of the aluminum material abuts against the bottom of the rotating ring 213, thereby determining the position of the aluminum material entering the H-shaped frame 14, which is convenient for the next step of processing.
[0065] To ensure that the bottom of the aluminum material abuts against the centering ring 211 and the side of the aluminum material abuts against the center column 210, the operator adjusts the position of the synchronization plate 216 according to the width of the aluminum material. When the synchronization plate 216 moves, it drives the slider 214 connected to it to move together. When the slider 214 moves, it drives the adjustment plate 215 to move together, so that the adjustment plate 215 rotates under the restriction of the center column 210. When the center column 210 moves, it drives the rotating plate 21 to rotate, thereby changing the distance between the center column 210 and the slider 214. After the distance between the center column 210 and the slider 214 changes, it will drive the centering ring 211 and the rotating ring 213 to move together, centering aluminum materials of different sizes and specifications, thereby improving the practicality of the device.
[0066] Step 3: When the drive motor 391 rotates, it drives the drive shaft 390 to rotate as well. One pair of drive shafts 390, through belt drive, can drive multiple drive shafts 390 to rotate together. The rotation of the drive shaft 390 drives the transmission rod 393 to rotate, which in turn drives the contact ring 394 to rotate. The rotation of the contact ring 394 drives the arc-shaped triangular block 395 to rotate. When the arc-shaped triangular block 395 contacts the gear ring 31, its rotation pushes the gear ring 31 downwards. This movement of the gear ring 31 drives the rotating shaft 15 and the upper roller 16 to move together, ensuring that the upper roller 16 is in close contact with the top of the aluminum material. Simultaneously... When the rotating shaft 15 moves, it can drive the convex rod 35 to move together. When the convex rod 35 moves, it can drive the spur gear 36 to move together. At this time, the upper roller 16 and the rotating shaft 15 no longer move. The arc-shaped triangular block 395 continues to rotate, causing the locking block 32 to enter the locking groove 33. When the gear ring 31 drives the locking block 32 into the locking groove 33, the drive shaft 390 rotates, which can drive the gear chain 392 to rotate together. When the gear chain 392 rotates, it can drive the spur gear 36 to rotate together. When the spur gear 36 rotates, it can drive the gear ring 31 to rotate together. When the gear ring 31 rotates, it can drive the rotating shaft 15 to rotate together. When the rotating shaft 15 rotates, it can drive the upper roller 16 to rotate together, driving the aluminum material to move forward.
[0067] Step 4: After the processed aluminum material passes through the limiting groove 42 and the square block 41 for a certain distance, the drive shaft 390 rotates, which drives the reciprocating screw 43 to rotate as well. The reciprocating screw 43 rotates, which drives the connecting rod 430 to move back and forth. The reciprocating movement of the connecting rod 430 drives the square block 41 to move as well. The movement of the square block 41 drives the take-up shaft 46 and the take-up ring 460 to move as well. The movement of the take-up ring 460 drives the arc-shaped triangular tooth 462 to move as well. When the arc-shaped triangular tooth 462 abuts against the rack 48, it drives the take-up ring 460 to move as well. When the take-up ring 460 rotates, it drives the take-up shaft 46 to rotate as well. The rotation of the take-up shaft 46 winds the steel cable 461 around it. As the steel cable 461 winds, it drives the cutting block 45 to move upwards under the constraint of the vertical plate 44. When the take-up ring 460 rotates to the empty position under the drive of the rack 48, the arc-shaped triangular teeth 462 are no longer constrained by the rack 48, causing the cutting block 45 to move downwards under gravity, cutting the processed aluminum material. The steel cable 461 then drives the take-up shaft 46 and the take-up ring 460 to reset. After the aluminum material is cut, the reciprocating screw 43 drives the square block 41 to reset. The reset of the square block 41 drives the take-up shaft 46 and the take-up ring 460 to reset together. The arc-shaped triangular teeth 462 then press against the rack 48, causing the rack 48 to slide downwards under the constraint of the limit block 47, preventing the take-up shaft 46 and the take-up ring 460 from rotating.
