Description

Technical Field

[0002] Aluminum is a lightweight metal material with good mechanical properties and excellent corrosion resistance, so it is widely used in many fields such as aerospace, automotive, construction, electronics, and consumer goods; the processing of aluminum materials mainly includes the following steps: die pressing, casting, and cutting and forming; there are various methods for cutting and forming aluminum materials, including sawing, laser cutting, water jet cutting, and numerical control cutting; and sawing is to use a sawing machine or a band saw for cutting, which can efficiently and accurately process aluminum materials. Compared with the other three cutting methods, it is suitable for large-scale production of aluminum materials;

[0003] When the existing tubular aluminum materials are cut on a sawing machine, a pressing device is required to fix and press the tubular aluminum materials, which can prevent the tubular aluminum materials 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 the cutting efficiency; and the device for pressing multiple aluminum tubes placed side by side is specifically designed to be wavy, because the wavy design can increase the contact area between the pressing device and the aluminum tubes, which helps to provide a stronger clamping force and prevent the multiple aluminum tubes placed side by side from moving during the cutting or processing process. However, when the wavy pressing device faces aluminum tubes with different diameters, it is necessary to stop the machine and replace the corresponding wavy pressing device, which not only reduces the cutting efficiency of the sawing machine, but also increases the labor intensity of the operator;

[0034] A positioning wheel 231, the positioning wheel 231 is rotatably connected to the lower end of the positioning block 23; hinge rods 24 distributed crosswise are rotatably connected to both sides of the positioning block 23; the hinge rods 24 between adjacent two positioning blocks 23 are rotatably connected; an electro-hydraulic push rod 25 is installed on one side of the pressing plate 2; one end of the electro-hydraulic push rod 25 is fixedly connected to the pressing plate 2, and the other end is connected to the positioning block 23 close to the stepping motor 124; a positioning belt 232 is arranged below the positioning wheel 231; the positioning belt 232 is fixedly installed on one side of the positioning block 23 close to the stepping motor 124; a winding unit is installed on the upper end of the pressing plate 2; the winding unit is used to wind the positioning belt 232.

[0035] As an implementation manner 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 pressing plate 2; a servo motor 31 is fixedly installed on the upper end of the pressing plate 2; the servo motor 31 is used to drive the winding rod 3 to rotate.

[0036] As an implementation manner of the present invention, a rotating cylinder 32 is rotatably connected to the surface of the winding rod 3; one end of the positioning belt 232 far from the stepping motor 124 is fixedly connected to the rotating cylinder 32; a slot 33 is formed on the surface of the winding rod 3; a tooth 331 is slidably and sealingly connected within the slot 33; the tooth 331 is connected to the bottom of the slot 33 through a connecting spring 332; an electromagnetic sheet 333 is embedded in the bottom of the slot 33; a tooth groove 321 matching with the tooth 331 is formed on the inner wall of the rotating cylinder 32;

[0037] During operation, when cutting existing tubular aluminum materials on a sawing machine 1, a pressing device is required to fix and press the tubular aluminum materials. This can prevent the tubular aluminum materials from moving or vibrating during the cutting process, thereby ensuring the cutting quality. Moreover, when cutting a large quantity of aluminum materials, multiple aluminum tubes are placed side by side to achieve simultaneous cutting and improve the cutting efficiency. The device for pressing multiple aluminum tubes placed side by side is specifically designed to be wavy. Because the wavy design can increase the contact area between the pressing device and the aluminum tubes, which helps to provide a stronger clamping force and prevent the multiple aluminum tubes placed side by side from moving during the cutting or processing. However, when the wavy pressing device faces aluminum tubes of different diameters, it is necessary to stop the machine and replace the corresponding wavy pressing device. This not only reduces the cutting efficiency of the sawing machine 1 but also increases the labor intensity of the operator.

[0038] In response to this, through the arrangement of the positioning wheels 231 and the positioning belt 232 in the present invention, the positioning wheels 231 can push the positioning belt 232 to descend. During the descent of the positioning belt 232, the positioning belt 232 can contact the aluminum tube. And under the obstruction of the aluminum tube, the positioning belt 232 can be bent and deformed, so that the positioning belt 232 between the two positioning wheels 231 can fit the aluminum tube between the two positioning wheels 231. Different-diameter aluminum tubes are pressed and clamped by the positioning belt 232 at the upper end of the sawing machine 1. Thus, there is no need for the operator to stop the machine and replace the pressing device, which not only improves the cutting efficiency of the sawing machine 1 but also reduces the labor intensity of the operator, further enhancing the practicality of the present invention.

[0039] 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 machine frame 11. Subsequently, the user places multiple aluminum tubes (tubular aluminum materials) of equal length on the sawing machine 1. At this time, the aluminum tubes are located between the push plate 13 and the machine frame 11. Then, the end of the aluminum tube away from the machine 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 towards the direction close to the machine frame 11, causing the push plate 13 to push the aluminum tube close to the machine frame 11, and making the end of the aluminum tube close to the machine frame 11 cross over the cutting groove 12 to the lower side of the pressing plate 2. At this time, the user manually pushes the multiple side-by-side aluminum tubes across one end of the pressing plate 2 to the center of the sawing machine 1 and they are in side-by-side contact with each other; then, according to the total diameter length of the multiple side-by-side aluminum tubes, the electro-hydraulic push rod 25 is controlled to operate, so that the electro-hydraulic push rod 25 can push the positioning block 23 close to the stepping motor 124 to move towards the direction close to the stepping motor 124; making the distance between the two positioning blocks 23 at both ends of the groove 22 be the total diameter length of the multiple side-by-side aluminum tubes. The user manually controls the multiple side-by-side aluminum tubes to cross over one end of the pressing plate 2 and 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 to descend, the pressing plate 2 can push the positioning belt 232 to accurately press the multiple side-by-side aluminum tubes below; since one end of the positioning belt 232 close to the stepping motor 124 is connected to the positioning block 23 at one end of the groove 22 close to the stepping motor 124, during the process of the electro-hydraulic push rod 25 pushing the positioning block 23 close to the stepping motor 124 to move, the positioning block 23 close to the stepping motor 124 can pull the positioning belt 232 to elongate. Since in the initial state, the positioning belt 232 is wound around the surface of the reel 3 on the surface of the rotating cylinder 32, and the electromagnetic sheet 333 in the slot 33 is in a power-off state, the tooth 331 in the slot 33 extends out of the slot 33 under the push of the connecting spring 332 and is located in the tooth groove 321, making the tooth 331 mesh with the tooth groove 321 on the inner wall of the rotating cylinder 32. Therefore, at this time, the electromagnetic sheet 333 is controlled to be powered on, so that the electromagnetic sheet 333 can adsorb the tooth 331 to squeeze the connecting spring 332 into the slot 33, making the tooth 331 entering the slot 33 extend out of the tooth groove 321 and separate from the rotating cylinder 32; as the positioning block 23 pulls the positioning belt 232 close to the stepping motor 124, the positioning belt 232 wound around one end of the rotating cylinder 32 drives the rotating cylinder 32 to rotate in the reverse direction, so that the positioning belt 232 wound around the rotating cylinder 32 is released;

[0040] During the process that the positioning block 23 near the stepper motor 124 moves to a specified distance, the positioning block 23 near the stepper motor 124 will pull the positioning block 23 in the groove 22 to move synchronously through the hinge rod 24. Since the positioning block 23 far from the stepper motor 124 is fixedly connected to the groove wall of the groove 22, and the adjacent two positioning blocks 23 are connected by the hinge rod 24 forming a structure similar to a four-bar linkage, and the adjacent two hinge rods 24 forming a structure similar to a four-bar linkage are also in a connected state, so the multiple positioning blocks 23 in the groove 22 and the hinge rod 24 jointly form a structure similar to a variable pitch linkage. Therefore, when the positioning block 23 near the stepper motor 124 moves, the positioning block 23 near the stepper motor 124 will pull the positioning block 23 to move synchronously through the hinge rod 24, and the distance between the adjacent two positioning blocks 23 remains equidistant, so that the distance between the adjacent two positioning blocks 23 is the diameter of the aluminum tube to be cut;Control the hydraulic push rod 21 to push the pressing plate 2 downwards, 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 lower groove 22 at the lower end. As the positioning belt 232 continuously descends, the positioning belt 232 can continuously approach the aluminum pipe below, enabling the aluminum pipe to contact the positioning belt 232. And the positioning block 23 drives the positioning wheel 231 to be above the two aluminum pipes. As the hydraulic push rod 21 continues to push the pressing plate 2 downwards, the pressing plate 2 pushes the positioning block 23 and the positioning wheel 231 downwards until the positioning wheel 231 pushes the positioning belt 232 downwards and is located between the two aluminum pipes and contacts the two aluminum pipes. At this time, the positioning belt 232 between the two positioning wheels 231 can be bent and deformed due to the obstruction of the aluminum pipes, making the deformed positioning belt 232 wavy, so that the wavy positioning belt 232 can wrap the aluminum pipe, thereby increasing the contact surface between the positioning belt 232 and the aluminum pipe, and further facilitating an increase in the friction force between the positioning belt 232 and the aluminum pipe. Subsequently, control the electromagnetic sheet 333 to cut off the power, so that the tooth 331 extends out of the slot 33 and contacts the inner wall of the rotating cylinder 32 under the pushing force of the restoring force of the connecting spring 332. 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, and the tooth 331 slides on the inner wall of the rotating cylinder 32 driven by the winding rod 3 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 pushing force of the connecting spring 332, enabling the winding rod 3 to drive the rotating cylinder 32 to rotate through the tooth 331, so that the rotating cylinder 32 can drive the positioning belt 232 fixedly connected thereto to rotate during the rotation process, and the positioning belt 232 is wound around the surface of the rotating cylinder 32. Since the positioning belt 232 below the pressing plate 2 semi-wraps the aluminum pipe, when the positioning belt 232 is wound by the rotating cylinder 32, the positioning belt 232 below the pressing plate 2 is stretched and in a taut state, so that the taut positioning belt 232 can be closely attached to the aluminum pipe, not only increasing the friction force generated by the positioning belt 232 on the aluminum pipe, but also improving the pressing and clamping effect of the positioning belt 232 on the aluminum pipe, helping to provide a stronger clamping force on the aluminum pipe, preventing the multiple juxtaposed aluminum pipes from moving during the cutting or processing process, ensuring the stability of the aluminum pipe cutting, and enhancing the actual application effect of the present invention; when the positioning belt 232 presses the aluminum pipe, control the driving motor 125 to operate, so that the driving motor 125 drives the saw blade 121 to rotate. Subsequently, control the stepping motor 124 to operate, so that the stepping motor 124 drives the screw rod 123 to rotate, and the screw rod 123 drives the slider 122 in spiral transmission connection with it to move away from the stepping motor 124, so that the slider 122 drives the saw blade 121 rotatably connected thereto to move synchronously, and the slider 122 drives the saw blade 121 to move along the cutting groove 12 towards the aluminum pipe, so that the rotating saw blade 121 can cut the juxtaposed aluminum pipes, and the aluminum pipes are cut into the required size and length;After the saw blade 121 finishes cutting the juxtaposed aluminum tubes, control the stepping motor 124 to rotate in the reverse direction, so that the stepping motor 124 can drive the slider 122 to drive the saw blade 121 to reset. After the saw blade 121 resets, the user first controls the servo motor 31 to rotate in the reverse direction, so that the servo motor 31 drives the rotating cylinder 32 to rotate, so that the positioning belt 232 wound on the surface of the rotating cylinder 32 is released, so that the positioning belt 232 wrapping the aluminum tube is in a slack state. At the same time, control the guide rail 14 to run, 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 have relative sliding, so that the cut end of the aluminum tube extends out of the frame 11. Until the extension length of the aluminum tube is a set value, control the servo motor 31 to drive the rotating cylinder 32 to rotate and make the positioning belt 232 wind on the rotating cylinder 32, so that the positioning belt 232 is tightened and presses the aluminum tube again; thus, a new round of cutting is carried out.

[0041] As an implementation manner of the present invention, a rectangular groove 233 is opened on the side wall of the positioning block 23; a rectangular rod 234 is slidably and sealingly connected in the rectangular groove 233; the rectangular rod 234 is fixedly connected with the groove wall of the groove 22 through a fixing spring 235; a cylindrical groove 236 communicating with the rectangular groove 233 is opened on the side wall of the positioning block 23; a cylindrical rod 237 is slidably and sealingly connected in the cylindrical groove 236; one end of the electro-hydraulic push rod 25 close to the hydraulic push rod 21 is fixedly connected with a U-shaped block 251.

[0042] As an implementation manner of the present invention, a T-shaped groove 26 is opened on the side of the positioning block 23 away from the hinge rod 24; one end of the positioning belt 232 close to the stepping motor 124 is fixedly connected with a T-shaped rod 261; the T-shaped rod 261 is slidably connected in the T-shaped groove 26.

[0043] As an implementation manner of the present invention, a blocking groove 27 communicating with the T-shaped groove 26 is opened on one side of the positioning block 23; a blocking rod 271 is rotatably connected in the blocking groove 27.

[0044] As an implementation manner of the present invention, the hinge rod 24 includes a straight rod 242 and a clamping rod 241; a straight rod 242 is rotatably connected to one side of two positioning blocks 23 at both ends of the groove 22; a circular groove 243 is opened 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 with the bottom of the circular groove 243 through a support spring 245; a clamping groove 246 is opened on the inner wall of the clamping rod 241.

[0045] As an implementation manner of the present invention, a push piece 28 is slidably connected to the side wall of the straight rod 242; the push piece 28 is connected with the connecting rod 244 through a steel wire rope 281;

[0046] During operation, in the initial state, the blocking rod 271 in the positioning block 23 near the stepping motor 124 is located in the blocking groove 27 communicating with the T-shaped groove 26, so that the blocking rod 271 blocks the T-shaped rod 261 in the T-shaped groove 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 near the stepping motor 124 away from the stepping motor 124, so that the positioning belt 232 below the positioning block 23 is in a relaxed state, and then pulls the blocking rod 271 in the T-shaped groove 26 to rotate downward, so that the blocking rod 271 located 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-shaped rod 261 in the T-shaped groove 26; at this time, the user can pull out the T-shaped rod 261 in the T-shaped groove 26, at this time, separate the positioning belt 232 from the positioning block 23, then take out the increased positioning block 23 and push the cylindrical rod 237 on one side of the positioning block 23 into the cylindrical groove 236; since the cylindrical groove 236 communicates with 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 into the groove 22; so that the positioning block 23 drives the rectangular rod 234 to be located in the groove 22, release the cylindrical rod 237, 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 is pushed by the restoring force of the fixing spring 235 to squeeze the hydraulic oil in the rectangular groove 233 into the cylindrical groove 236, 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 is in sliding contact 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;

[0047] The connection between the positioning block 23 and the electro-hydraulic push rod 25 is achieved through a U-shaped block 251 and a 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 within 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 using 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 within 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. Then, control the electro-hydraulic push rod 25 to push the U-shaped block 251 over the positioning block 23. When inserting a new positioning block 23 into the groove 22, only need to place the new positioning block 23 below the U-shaped block 251, so that the cylindrical rod 237 on one side of the new positioning block 23 is directly below the U-shaped groove of the U-shaped block 251; when the insertion of the new positioning block 23 is completed, release the cylindrical rod 237, so that the cylindrical rod 237 can extend out of the cylindrical groove 236 under the push of hydraulic oil, and the cylindrical rod 237 extending out of the cylindrical groove 236 can be inserted into the U-shaped groove of the U-shaped block 251, thus realizing the connection between the positioning block 23 and the electro-hydraulic push rod 25; for the installation of the hinge rod 24 between two adjacent positioning blocks 23, first connect the hinge rod 24 group similar to a four-bar linkage on one side of the new positioning block 23 with the hinge rod 24 group similar to a four-bar linkage on one side of the adjacent positioning block 23, that is, connect the clamping rod 241 in the hinge rod 24 group of the new positioning block 23 with the straight rod 242 in another hinge rod 24 group. First, push the push piece 28 on one side of the straight rod 242, so that the push piece 28 can pull the connecting rod 244 connected to it through the steel wire rope 281 to squeeze the support spring 245 into the round groove 243. Then, align the clamping rod 241 of the new hinge rod 24 group with the end of the straight rod 242 of the old hinge 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 card slot 246 of the clamping rod 241 is directly opposite to the round groove 243 of the straight rod 242. Release the push piece 28, so that the connecting rod 244 extends out of the round groove 243 and enters the card slot 246 under the pushing force of the restoring force of the support spring 245, thereby connecting the straight rod 242 and the clamping rod 241 of the two hinge rod 24 groups by the connecting rod 244; thus completing the connection of the new positioning block 23. Finally, insert 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 rotate the stop rod 271 upward so that the stop rod 271 is inserted into the blocking groove 27, so that the stop rod 271 blocks the T-shaped rod 261 in the T-shaped groove 26, thereby ensuring the stable connection between the positioning belt 232 and the new positioning block 23 through the T-shaped rod 261; and for each additional aluminum tube, one positioning block 23 needs to be added;

[0048] In the present invention, by setting the positioning block 23 to be freely disassembled and assembled, it is convenient for the user to add the positioning block 23 to cooperate with the stable pressing of the added aluminum tubes, which can prevent the omission of the aluminum tubes after the quantity is increased, so that the aluminum tube groups after the quantity is increased can be stably pressed and clamped by the positioning belt 232. Therefore, it is not necessary for the user to replace the entire positioning block 23 assembly, which not only reduces the downtime for replacement and improves production efficiency, but also does not require preparing too many positioning block 23 assemblies, thus saving costs. In addition, storing and inspecting the single positioning block 23 separately is beneficial to the maintenance and repair of the positioning block 23, greatly prolonging the service life of the positioning block 23 and further enhancing the practical application effect of the present invention.
