Therefore, it is widely used in aerospace, automobile, construction, electronics and consumer products. Aluminum processing mainly includes the following steps: die-casting, casting and cutting. There are many methods for aluminum cutting, including sawing, laser cutting, water jet cutting and CNC cutting. Sawing is cutting with a sawing machine or band saw, which can process aluminum efficiently and accurately. Compared with the other three cutting methods, it is suitable for large-scale aluminum production. When cutting existing tubular aluminum materials on a sawing machine, a clamping device is required to fix and clamp the tubular aluminum materials, so as to prevent the tubular aluminum materials from moving or vibrating during the cutting process, thereby ensuring the cutting quality; and when cutting large quantities of aluminum materials, multiple aluminum tubes are placed side by side to achieve simultaneous cutting and improve cutting efficiency; and the device for clamping multiple aluminum tubes placed side by side is specially designed to be wavy, because the wavy design can increase the contact area between the clamping device and the aluminum tube, which helps to provide a stronger clamping force and prevent multiple aluminum tubes placed side by side from moving during the cutting or processing process.

[0018] As an embodiment of the present invention, the winding unit includes a winding rod 3; the winding rod 3 is rotatably connected to the upper end of the pressure plate 2; a servo motor 31 is fixedly installed on the upper end of the pressure plate 2; the servo motor 31 is used to drive the pressure plate 2 to rotate.

[0019] As an embodiment of the present invention, the surface of the winding rod 3 is rotatably connected with a rotating drum 32; the end of the positioning belt 232 away from the stepping motor 124 is fixedly connected to the rotating drum 32; a slot 33 is provided on the surface of the winding rod 3; a tooth 331 is slidably and sealedly connected in the slot 33; the tooth 331 is connected to the bottom of the slot 33 by a connecting spring 332; an electromagnetic sheet 333 is embedded in the bottom of the slot 33; a tooth groove 321 matching the tooth 331 is provided on the inner wall of the rotating drum 32; During operation, when the existing tubular aluminum material is cut on the sawing machine 1, a clamping device is required to fix and clamp the tubular aluminum material, so as to prevent the tubular aluminum material from moving or vibrating during the cutting process, thereby ensuring the cutting quality; and when cutting a large number of aluminum materials, multiple aluminum tubes are placed side by side to achieve simultaneous cutting and improve cutting efficiency; and the device for clamping multiple aluminum tubes placed side by side is specially designed to be wavy, because the wavy design can increase the contact area between the clamping device and the aluminum tube, which helps to provide a stronger clamping force and prevent multiple aluminum tubes placed side by side from moving during the cutting or processing process. However, when the wavy clamping device faces aluminum tubes of different diameters, it is necessary to stop the machine and replace the corresponding wavy clamping device, which not only reduces the cutting efficiency of the sawing machine 1, but also increases the labor intensity of the operator; In this regard, the present invention arranges the positioning wheel 231 and the positioning belt 232 so that the positioning wheel 231 can push the positioning belt 232 to descend, so that the positioning belt 232 can contact the aluminum tube during the descent, and the positioning belt 232 can be bent and deformed under the obstruction of the aluminum tube, so that the positioning belt 232 between the two positioning wheels 231 can fit the aluminum tube between the two positioning wheels 231, so that the aluminum tubes of different diameters are clamped and clamped on the upper end of the sawing machine 1 by the positioning belt 232, so that the operator does not need to stop the machine to replace the clamping device, which not only improves the cutting efficiency of the sawing machine 1, but also reduces the labor intensity of the operator, so that the practicality of the present invention is further improved; In the initial state, the user controls the guide rail 14 to drive the push plate 13 to the end of the guide rail 14 away from the frame 11, and then the user places multiple aluminum tubes (tubular aluminum materials) of equal length on the sawing machine 1. At this time, the aluminum tube is located between the push plate 13 and the frame 11, and then the end of the aluminum tube away from the frame 11 is pushed to contact the push plate 13, and the guide rail 14 is controlled to operate, so that the guide rail 14 drives the push plate 13 to move toward the frame 11, so that the push plate 13 pushes the aluminum tube to the frame 11, so that the end of the aluminum tube close to the frame 11 passes over the cutting groove 12 to the bottom of the pressing plate 2, and at this time, the user manually pushes the multiple aluminum tubes arranged side by side. The tubes pass over one end of the pressing plate 2 to the center of the sawing machine 1, and are in contact with each other side by side; then, according to the total length of the diameters of the multiple aluminum tubes arranged side by side, the electric hydraulic push rod 25 is controlled to operate so that the electric hydraulic push rod 25 can push the positioning block 23 close to the stepping motor 124 to move in the direction close to the stepping motor 124; so that the distance between the two positioning blocks 23 at both ends of the groove 22 is the total length of the diameters of the multiple aluminum tubes arranged side by side, and the user manually controls one end of the multiple aluminum tubes arranged side by side to pass over the pressing plate 2 and to be located between the two positioning blocks 23 at both ends of the groove 22, so that when the hydraulic push rod 21 pushes the pressing plate 2 down, the pressing plate 2 pushes The positioning belt 232 accurately compresses the multiple aluminum tubes arranged side by side below; since the end of the positioning belt 232 close to the stepper motor 124 is connected to the positioning block 23 close to the end of the stepper motor 124 in the groove 22, when the electro-hydraulic push rod 25 pushes the positioning block 23 close to the stepper motor 124 to move, the positioning block 23 close to the stepper motor 124 can pull the positioning belt 232 to extend. In the initial state, the positioning belt 232 is wound around the surface of the reel 32, and the electromagnetic sheet 333 in the slot 33 is in a power-off state, so that the teeth 331 in the slot 33 are connected to the spring 3 The tooth 331 is pushed out of the slot 33 by the positioning block 23 and is located in the tooth groove 321, so that the tooth 331 is meshed with the tooth groove 321 on the inner wall of the rotating drum 32. Therefore, the electromagnetic sheet 333 is energized at this time, so that the electromagnetic sheet 333 can absorb the tooth 331 and squeeze the connecting spring 332 to enter the slot 33, so that the tooth 331 entering the slot 33 extends out of the tooth groove 321 and separates from the rotating drum 32; as the positioning block 23 pulls the positioning belt 232 close to the stepping motor 124, the positioning belt 232 is wound around one end of the rotating drum 32, driving the rotating drum 32 to rotate in the opposite direction, so that the positioning belt 232 wound on the rotating drum 32 is released; In the process of the positioning block 23 close to the stepper motor 124 moving to the specified distance, the positioning block 23 close to the stepper motor 124 will pull the positioning block 23 in the groove 22 to move synchronously through the hinged rod 24. Since the positioning block 23 far away from the stepper motor 124 is fixedly connected to the groove wall of the groove 22, and the two adjacent positioning blocks 23 are connected by the hinged rod 24 that forms a four-bar linkage, and the two adjacent hinged rods 24 that form a four-bar linkage are also in a connected state, the multiple positioning blocks 23 in the groove 22 and the hinged rod 24 together form a structure similar to a connecting rod variable pitch. Therefore, when the positioning block 23 close to the stepper motor 124 moves, the positioning block 23 close to the stepper motor 124 will pull the positioning block 23 to move synchronously through the hinged rod 24, and the distance between the two adjacent positioning blocks 23 is kept equidistant, so that the distance between the two adjacent positioning blocks 23 is the diameter of the cut aluminum tube;The hydraulic push rod 21 is controlled to push the pressing plate 2 down, so that the pressing plate 2 drives the positioning belt 232 below the positioning wheel 231 to descend through the positioning block 23 in the groove 22 at the lower end. As the positioning belt 232 continues to descend, the positioning belt 232 can continue to approach the aluminum tube below, so that the aluminum tube can contact the positioning belt 232, and the positioning block 23 drives the positioning wheel 231 to be located above the two aluminum tubes. As the hydraulic push rod 21 pushes the pressing plate 2 to continue to descend, the pressing plate 2 pushes the positioning block 23 and the positioning wheel 231 to descend until the positioning wheel 231 drives the positioning belt 232 to descend and is located between the two aluminum tubes and contacts the two aluminum tubes. At this time, the positioning belt 232 located between the two positioning wheels 231 can be blocked by the aluminum tubes and bend and deform. , so that the deformed positioning belt 232 becomes wavy, so that the wavy positioning belt 232 can wrap the aluminum tube, thereby increasing the contact surface between the positioning belt 232 and the aluminum tube, which is beneficial to increase the friction between the positioning belt 232 and the aluminum tube, and then control the electromagnetic sheet 333 to be powered off, so that the tooth 331 is pushed out of the slot 33 by the restoring force of the connecting spring 332 and contacts the inner wall of the rotating drum 32, and control the servo motor 31 to drive the winding rod 3 to rotate, so that the winding rod 3 can drive the tooth 331 to rotate, so that the tooth 331 is driven by the winding rod 3 to slide on the inner wall of the rotating drum 32 until the tooth 331 rotates to the notch of the tooth groove 321. At this time, the tooth 331 enters the tooth groove 321 under the push of the connecting spring 332, so that The winding rod 3 can drive the rotating drum 32 to rotate through the teeth 331, so that the rotating drum 32 can drive the positioning belt 232 fixed thereto to rotate during the rotation process, so that the positioning belt 232 is wound around the surface of the rotating drum 32. Since the positioning belt 232 under the pressure plate 2 half wraps the aluminum tube, when the positioning belt 232 is wound by the rotating drum 32, the positioning belt 232 under the pressure plate 2 is stretched and is in a taut state, so that the taut positioning belt 232 can fit tightly with the aluminum tube, which not only increases the friction force generated by the positioning belt 232 on the aluminum tube, but also improves the pressing and clamping effect of the positioning belt 232 on the aluminum tube, which helps to provide a stronger clamping force for the aluminum tube and prevent multiple aluminum tubes placed side by side from moving during cutting or processing. , to ensure the stability of aluminum tube cutting, so that the practical application effect of the present invention is improved; when the positioning belt 232 presses the aluminum tube, the driving motor 125 is controlled to operate, so that the driving motor 125 drives the saw disk 121 to rotate, and then the stepping motor 124 is controlled to operate, so that the stepping motor 124 drives the screw 123 to rotate, so that the screw 123 drives the slider 122 connected to its spiral transmission to move away from the stepping motor 124, so that the slider 122 drives the saw disk 121 connected to its rotation to move synchronously, so that the slider 122 drives the saw disk 121 to move along the cutting groove 12 in the direction close to the aluminum tube, so that the rotating saw disk 121 can cut the side-by-side aluminum tubes, so that the aluminum tubes are cut into the required size and length;When the saw disc 121 has finished cutting the aluminum tubes in parallel, the stepper motor 124 is controlled to rotate in the reverse direction, so that the stepper motor 124 can drive the slider 122 to drive the saw disc 121 to reset. After the saw disc 121 is reset, the user first controls the servo motor 31 to rotate in the reverse direction, so that the servo motor 31 drives the rotating drum 32 to rotate, so that the positioning belt 232 wrapped on the surface of the rotating drum 32 is released, so that the positioning belt 232 wrapped around the aluminum tube is in a relaxed state, and at the same time controls the guide rail 14 to operate, so that the guide rail 14 drives the push plate 13 to push the aluminum tube to move, so that the aluminum tube and the positioning belt 232 slide relative to each other, so that the cut end of the aluminum tube extends out of the frame 11, until the extended length of the aluminum tube reaches the set value, the servo motor 31 is controlled to drive the rotating drum 32 to rotate and the positioning belt 232 is wound around the rotating drum 32, so that the positioning belt 232 is tightened and the aluminum tube is pressed again; thus a new round of cutting is performed. ;

[0022] As an embodiment of the present invention, a blocking groove 27 communicating with the T-shaped groove 26 is formed on one side of the positioning block 23 ; a blocking rod 271 is rotatably connected in the blocking groove 27 .

[0023] As an embodiment of the present invention, the hinged rod 24 includes a straight rod 242 and a clamping rod 241; the two positioning blocks 23 located at both ends of the groove 22 are rotatably connected to the straight rod 242 on one side; a circular groove 243 is provided on the side wall of the straight rod 242; a connecting rod 244 is slidably connected in the circular groove 243; the connecting rod 244 is fixedly connected to the bottom of the circular groove 243 by a support spring 245; and a clamping groove 246 is provided on the inner wall of the clamping rod 241.

[0024] As an embodiment of the present invention, the side wall of the straight rod 242 is slidably connected with a push piece 28; the push piece 28 and the connecting rod 244 are connected by a steel wire rope 281; During operation, in the initial state, the blocking rod 271 in the positioning block 23 close to the stepping motor 124 is located in the blocking groove 27 connected to the T-slot 26, so that the blocking rod 271 blocks the T-bar 261 in the T-slot 26; when the number of aluminum tubes to be cut needs to be increased, the user not only needs to increase the number of aluminum tubes on the sawing machine 1, but also needs to increase the number of positioning blocks 23; when the user needs to increase the number of positioning blocks 23, the user first controls the electro-hydraulic push rod 25 to pull the positioning block 23 close to the stepping motor 124 away from the The stepper motor 124 makes the positioning belt 232 under the positioning block 23 in a relaxed state, and then pulls the blocking rod 271 in the T-slot 26 to rotate downward, so that the blocking rod 271 in the blocking groove 27 rotates and extends out of the blocking groove 27, so that the blocking rod 271 no longer blocks the T-bar 261 in the T-slot 26; at this time, the user can pull out the T-bar 261 in the T-slot 26, at this time, separate the positioning belt 232 from the positioning block 23, and then take out the added positioning block 23 and push the positioning block 23 to move forward. The cylindrical rod 237 on the side enters the cylindrical groove 236; since the cylindrical groove 236 is connected to the rectangular groove 233 and the cylindrical groove 236 is filled with hydraulic oil, during the process of the cylindrical rod 237 being inserted into the cylindrical groove 236, the cylindrical rod 237 can push the hydraulic oil in the cylindrical groove 236 into the rectangular groove 233; so that the rectangular rod 234 in the rectangular groove 233 is pushed by the hydraulic oil to squeeze the fixing spring 235 into the rectangular groove 233, and then push the end of the positioning block 23 equipped with the rectangular rod 234 to be inserted into the groove 22; so that The positioning block 23 drives the rectangular rod 234 to be located in the groove 22, and the cylindrical rod 237 is released. At this time, the cylindrical rod 237 no longer generates a driving force on the hydraulic oil in the cylindrical groove 236, so that the rectangular rod 234 squeezes the hydraulic oil in the rectangular groove 233 into the cylindrical groove 236 under the driving force of the restoring force of the fixing spring 235, so that the rectangular rod 234 extends out of the rectangular groove 233 and is located in the groove 22, so that the rectangular rod 234 slides and contacts with the groove wall of the groove 22, so that the positioning block 23 is clamped in the groove 22 through the rectangular rod 234; The connection between the positioning block 23 and the electro-hydraulic push rod 25 is through the U-shaped block 251 and the cylindrical rod 237, that is, the electro-hydraulic push rod 25 pushes the cylindrical rod 237 through the U-shaped block 251 to drive the positioning block 23 to slide in the groove 22. Therefore, when disassembling the positioning block 23 and the electro-hydraulic push rod 25, the user first uses a pressing tool, such as a ratchet wrench, to push the cylindrical rod 237 on one side of the positioning block 23 connected to the electro-hydraulic push rod 25 into the cylindrical groove 236, so that the cylindrical rod 237 entering the cylindrical groove 236 is no longer located in the U-shaped groove of the U-shaped block 251; that is, at this time, the cylindrical rod 237 is separated from the U-shaped block 251, and then the electro-hydraulic push rod 25 is controlled to push the U-shaped block 251 over the positioning block 23, and then When inserting the new positioning block 23 into the groove 22, it is only necessary to place the new positioning block 23 under the U-shaped block 251 so that the columnar rod 237 on one side of the new positioning block 23 is located directly under the U-shaped groove of the U-shaped block 251; when the new positioning block 23 is inserted, the columnar rod 237 is loosened so that the columnar rod 237 can extend out of the columnar groove 236 under the push of the hydraulic oil, and the columnar rod 237 extending out of the columnar groove 236 can be inserted into the U-shaped groove of the U-shaped block 251, thereby realizing the connection between the positioning block 23 and the electro-hydraulic push rod 25; and the installation of the hinged rod 24 between two adjacent positioning blocks 23 is to first connect the hinged rod 24 group similar to the four-bar linkage mechanism on one side of the new positioning block 23 with the adjacent One side of the positioning block 23 is connected with a hinged rod 24 group similar to a four-bar linkage mechanism, that is, the clamping rod 241 in the hinged rod 24 group of the new positioning block 23 is connected with the straight rod 242 in the other hinged rod 24 group, and the push piece 28 on one side of the straight rod 242 is pushed first, so that the push piece 28 can pull the connecting rod 244 connected thereto through the wire rope 281 to squeeze the support spring 245 into the circular groove 243, and then the clamping rod 241 of the new hinged rod 24 group is aligned with one end of the straight rod 242 of the hinged rod 24 group close to the connecting rod 244, so that the straight rod 242 is inserted into the U-shaped groove of the clamping rod 241 until the clamping groove 246 of the clamping rod 241 is aligned with the circular groove 243 of the straight rod 242, and the push piece 28 is released. The connecting rod 244 extends out of the circular groove 243 and enters the clamping groove 246 under the push of the restoring force of the supporting spring 245, so that the connecting rod 244 connects the straight rod 242 and the clamping rod 241 of the two articulated rod 24 groups; thereby completing the connection of the new positioning block 23, and finally inserting the T-shaped rod 261 fixedly connected to one end of the positioning belt 232 into the T-shaped groove 26 of the new positioning block 23, and then rotating the blocking rod 271 upward, so that the blocking rod 271 is inserted into the blocking groove 27, so that the blocking rod 271 blocks the T-shaped rod 261 in the T-shaped groove 26, thereby ensuring that the positioning belt 232 is stably connected to the new positioning block 23 through the T-shaped rod 261; and for each additional aluminum tube, a positioning block 23 needs to be added; The present invention can freely disassemble and assemble the positioning block 23, so that the user can add the positioning block 23 to cooperate with the added aluminum tube to stably compress it, which can prevent the aluminum tubes after the increase in number from being missed, so that the aluminum tube group after the increase in number can be stably compressed and clamped by the positioning belt 232, thereby eliminating the need for the user to completely replace the entire positioning block 23 assembly, which not only reduces the downtime for replacement and improves production efficiency; but also eliminates the need to prepare too many positioning block 23 assemblies, thereby saving costs. In addition, separate storage and inspection of a single positioning block 23 is conducive to the maintenance and repair of the positioning block 23, greatly extending the service life of the positioning block 23, and further improving the practical application effect of the present invention.
