Description

Technical Field

[0001] This utility model relates to the field of aluminum plate cutting technology, specifically to an aluminum plate curve cutting machine. Background Technology

[0002] Aluminum plates are rectangular sheets rolled from aluminum ingots. During processing, to produce more complex shapes, a curve cutting machine is typically used for curve cutting. In some aluminum plate curve cutting machines, workers place the aluminum plate on the cutting table, then adjust its position according to its length and width. A limiting component then fixes the plate in place for curve cutting. During curve cutting, a traveling unit moves the cutting section in a curved path to achieve the desired cut. However, because the curve cutting trajectory is usually programmed by a PLC, the initial cutting point is generally the same for all aluminum plates. Therefore, each time the plate is placed for curve cutting, workers must adjust its position on the cutting table according to its length and width, and then use the limiting component to fix it in place to ensure the initial cutting point remains the same. This process is quite cumbersome. Therefore, we propose an aluminum plate curve cutting machine. Utility Model Content

The input terminal of the second motor 9 is electrically connected to the output terminal of the microcontroller 2. The output ends are all fixedly connected to the adjacent studs 8. When using the device to perform curve cutting on the aluminum plate, the aluminum plate is first placed above the roller 73. The microcontroller 2 starts the laser cutting head 6 to perform curve cutting on the fixed aluminum plate. During the curve cutting process, the microcontroller 2 starts the upper motor 9 so that its output shaft drives the upper stud 8 to rotate forward or backward. The upper stud 8 rotates forward or backward, thereby causing the laser cutting head 6 to move laterally left and right along the guide rail 5, thereby adjusting the lateral position of the cutting point of the aluminum plate curve cutting part. The microcontroller 2 starts the lower motor 9 so that its output shaft drives the lower stud 8 to rotate forward or backward. The lower stud 8 rotates forward or backward, thereby causing the longitudinal moving frame 4 to move longitudinally back and forth along the guide rail 3, thereby adjusting the longitudinal position of the cutting point of the aluminum plate curve cutting part. It also includes a self-fixing mechanism 7.

[0021] Self-fixing mechanism 7: It includes an electro-hydraulic actuator 71, a rectangular frame 72, rollers 73, a transverse centering fixing component 74, and a longitudinal centering fixing component 75. The electro-hydraulic actuator 71 is respectively set at the four corners of the bottom wall of the curved cutting table 1. A rectangular frame 72 is provided between the telescopic ends of the electro-hydraulic actuator 71. The rectangular frame 72 is rotatably connected to the evenly distributed rollers 73 through a bearing. The transverse centering fixing component 74 and the longitudinal centering fixing component 75 are respectively provided inside the rectangular frame 72. The output end of the microcontroller 2 is electrically connected to the laser cutting head 6 and the input end of the electro-hydraulic actuator 71. The transverse centering fixing component 74 includes a cross groove 741, a transverse sliding seat 743, a rubber pad 744, and a pressure sensor 745. The cross groove 741 is respectively opened Located at the front and rear ends of the rectangular frame 72, two laterally symmetrically distributed transverse sliding seats 743 are slidably connected between the cross grooves 741. Each transverse sliding seat 743 has a rubber pad 744 and a pressure sensor 745 on its opposite inner surface. The pressure sensors 745 are bidirectionally electrically connected to the microcontroller 2. The transverse centering fixing assembly 74 also includes a bidirectional lead screw 742, a connecting seat 746, a first gear 747, a second gear 748, and a first motor 749. The bidirectional lead screw 742 is rotatably connected to the front cross groove 741 via a bearing 3. Both ends of the bidirectional lead screw 742 are threadedly connected to the adjacent transverse sliding seats 743. The lower front end of the rectangular frame 72 has a connecting seat 746, and the right side of the connecting seat 746 has a first motor 749. The motor 749's output... The input end is electrically connected to the output end of the microcontroller 2. The output shaft of the motor 749 is equipped with a gear 747. A groove is provided on the lower side of the rectangular frame 72. A gear 748 is provided at the rear end of the bidirectional lead screw 742. The gear 748 is located in the groove and meshes with the gear 747. The longitudinal centering fixing component 75 includes an electro-hydraulic actuator 751, a connecting rod 752, a longitudinal shift seat 753, a ball 754, and a laser sensor 755. The electro-hydraulic actuator 751 is respectively set at the front and rear ends of the lower side of the rectangular frame 72. The input end of the electro-hydraulic actuator 751 is electrically connected to the output end of the microcontroller 2. The telescopic end of the electro-hydraulic actuator 751 is provided with a longitudinal shift seat 753 through the connecting rod 752. The inner surfaces of the two longitudinal shift seats 753 are respectively connected. Each section has evenly distributed semicircular grooves, and each semicircular groove is rotatably connected to a ball bearing 754. Laser sensors 755 are installed on the opposing inner surfaces of the two longitudinal moving seats 753. Corrugated tubes 10 are installed between the front left and right ends of the longitudinal moving frame 4 and the adjacent laser cutting head 6, between the front and rear right ends of the curved cutting table 1 and the adjacent longitudinal moving frame 4, between the left and right ends of the front cross groove 741 and the adjacent transverse moving seat 743, and between the opposing inner surfaces of the two transverse moving seats 743. The corrugated tubes 10 are movably sleeved on the outer ends of the adjacent studs 8 and the bidirectional lead screw 742. When the operator activates the microcontroller 2, the telescopic end of the electro-hydraulic actuator 71 drives the rectangular frame 72 to move vertically, thereby adjusting the vertical position of the curved cutting position of the aluminum plate.Subsequently, the microcontroller 2 activates the electro-hydraulic actuator 751, causing its telescopic end to move the corresponding longitudinal shift seat 753 towards the longitudinal center of the device via the connecting rod 752. The two longitudinal shift seats 753 move closer together, thus longitudinally limiting the curved cutting of the aluminum plate. During this process, the microcontroller 2 activates the laser sensor 755, which emits a light signal that illuminates the adjacent side of the aluminum plate and reflects back to its initial position. Based on the propagation time and speed of the light signal, the distance between the front and rear sides of the aluminum plate and the adjacent longitudinal shift seats 753 is obtained, and the result is transmitted to the microcontroller 2 as an electrical signal. The microcontroller 2 then controls the two electro-hydraulic actuators 751 to move their telescopic ends towards the longitudinal center of the device with the same unit displacement. When the data uploaded by the optical sensor 755 approaches zero, the microcontroller 2 shuts off the electro-hydraulic actuator 751, thereby achieving automatic longitudinal limiting of the aluminum plate curve cutting through the two longitudinal sliding seats 753. Subsequently, the microcontroller 2 starts the motor 749, causing its output shaft to drive the gear 747. The gear 747, through a threaded connection with the gear 748, causes the gear 748 to drive the bidirectional lead screw 742 to rotate. During the rotation of the bidirectional lead screw 742, the two transverse sliding seats 743 move along the cross groove 741 towards the transverse center of the device, thus providing transverse limiting for the aluminum plate curve cutting. During this process, the microcontroller 2 activates the pressure sensor 745, which utilizes the piezoresistive effect of single-crystal silicon material and integrated circuit technology. The sensor, made of single-crystal silicon material, exhibits a change in resistivity when subjected to force. A measuring circuit outputs an electrical signal proportional to this force change, thus measuring the pressure on the pressure sensor 745 itself. The measurement result is then transmitted as an electrical signal to the microcontroller 2. During the process of the two transverse sliding seats 743 approaching each other, when one side of the transverse sliding seat 743 contacts the side of the aluminum plate, it pushes the aluminum plate laterally along the upper end of the roller 73. (During this lateral movement, both the front and rear sides of the aluminum plate contact adjacent rolling balls 754, which adaptively rotate around their corresponding semicircular grooves. The rolling balls 754 reduce the lateral resistance exerted on the aluminum plate by the longitudinal sliding seat 753 during the lateral movement.) At this time, the transverse sliding seat 743, due to its contact with the aluminum plate... Since there is side contact, the pressure sensor 745 on the transverse sliding seat 743 will display a measurement value. When both pressure sensors 745 measure the pressure value between the aluminum plate and the transverse sliding seat 743, and the pressure value tends to a certain level, the microcontroller 2 will shut down the motor 749 based on the result, thereby realizing the automatic lateral limit of the aluminum plate curve cutting. (During this process, the transverse sliding seat 743 is pressed and fixed to the left and right sides of the aluminum plate by the rubber pads 744. The rubber pads 744 increase the frictional resistance between the transverse sliding seat 743 and the left and right sides of the aluminum plate, avoiding relative sliding between the two, and thus improving the fixing effect between them.) The operation is convenient and intelligent. During the use of the device, the exposed parts of the stud 8 and the bidirectional lead screw 742 are wrapped by the bellows 10.To prevent dust and slag from interfering with the transmission of the stud 8 and the double-acting lead screw 742, this device, through transmission and detection elements, can automatically center and fix aluminum plates of different sizes during curved cutting. This facilitates subsequent curved cutting operations on the aluminum plates. The centering and fixing operation for curved cutting of aluminum plates is convenient and intelligent, requiring no manual intervention.

[0022] The working principle of the aluminum plate curve cutting machine provided by this utility model is as follows: When using the device to perform curve cutting on the aluminum plate, the aluminum plate is first placed above the roller 73. Then, the operator starts the microcontroller 2, causing the telescopic end of the electro-hydraulic push rod 71 to drive the rectangular frame 72 to move vertically, thereby adjusting the vertical position of the aluminum plate curve cutting position. Then, the microcontroller 2 starts the electro-hydraulic push rod 751, causing its telescopic end to drive the corresponding longitudinal shift seat 753 to move towards the longitudinal center of the device through the connecting rod 752. The two longitudinal shift seats 753 move closer to each other, thereby longitudinally limiting the aluminum plate curve cutting. During this process, the microcontroller 2 starts the laser sensor 755. The laser sensor 755 emits a light signal to illuminate the adjacent side of the aluminum plate and reflects it back to the initial position. The optical signal propagation time and speed are measured to obtain the distance between the front and rear sides of the aluminum plate and the adjacent longitudinal shifter 753. The result is transmitted to the microcontroller 2 as an electrical signal. The microcontroller 2 controls the two electro-hydraulic actuators 751 to move the longitudinal shifter 753 towards the longitudinal center of the device with the same unit displacement at their extension ends. When the data uploaded by the two laser sensors 755 approach zero, the microcontroller 2 closes the electro-hydraulic actuators 751. The two longitudinal shifters 753 thus achieve automatic longitudinal limiting for the curved cutting of the aluminum plate. Subsequently, the microcontroller 2 starts the motor 749, whose output shaft drives the gear 747. The gear 747 is threadedly connected to the gear 748, which in turn drives the bidirectional lead screw 742 to rotate. During the rotation of the bidirectional lead screw 742, the two transverse sliding seats 743 move along the cross groove 741 towards the transverse center of the device via a threaded connection, thereby limiting the transverse movement of the aluminum plate during curved cutting. During this process, the microcontroller 2 activates the pressure sensor 745. The pressure sensor 745 is a sensor made using the piezoresistive effect of single-crystal silicon material and integrated circuit technology. When single-crystal silicon material is subjected to force, its resistivity changes. A measuring circuit can then output an electrical signal proportional to the force change, thereby measuring the pressure on the pressure sensor 745 itself and transmitting the measurement result as an electrical signal to the microcontroller 2. As the two transverse sliding seats 743 move closer together, when one side of the transverse sliding seat 743 contacts the side of the aluminum plate, it pushes the aluminum plate along the roller... The upper end of cylinder 73 moves laterally (during the lateral movement of the aluminum plate, both the front and rear sides of the aluminum plate contact the adjacent rolling balls 754, and the rolling balls 754 adaptively rotate around the corresponding semicircular groove, thereby reducing the lateral resistance exerted on the aluminum plate by the longitudinal moving seat 753 during the lateral movement). At this time, since the transverse moving seat 743 is in contact with the side of the aluminum plate, the pressure sensor 745 on the transverse moving seat 743 will display a measurement value. When both pressure sensors 745 measure the pressure value between the aluminum plate and the transverse moving seat 743, and the pressure value tends to a certain level, the microcontroller 2 shuts down motor 749 according to the result, thereby realizing the lateral automatic limit of the aluminum plate curve cutting (during this process, the transverse moving seat 743 is pressed and fixed to the left and right sides of the aluminum plate by the rubber pads 744).Rubber pads 744 increase the frictional resistance between the transverse sliding seat 743 and the left and right sides of the aluminum plate, preventing relative sliding and improving the fixing effect. Operation is convenient and intelligent. The microcontroller 2 then starts the laser cutting head 6 to perform curved cutting on the fixed aluminum plate. The microcontroller 2 starts the upper motor 9, causing its output shaft to drive the upper stud 8 to rotate forward or backward. The upper stud 8, by rotating forward or backward, causes the laser cutting head 6 to move laterally left and right along the guide rail 5, thus cutting the aluminum plate in a curved manner. The cutting point of the cutting section is adjusted laterally. The microcontroller 2 starts the lower motor 9, causing its output shaft to drive the lower stud 8 to rotate forward or backward. The stud 8's rotation causes the longitudinal moving frame 4 to move longitudinally back and forth along the guide rail 3, thus adjusting the longitudinal position of the cutting point of the aluminum plate's curved section. During use, the exposed portions of the stud 8 and the bidirectional lead screw 742 are wrapped with corrugated pipe 10 to prevent dust and cutting debris from entering and interfering with the transmission of the stud 8 and the bidirectional lead screw 742.

[0023] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be a COP8CBE9, the laser cutting head 6 can be an LC80 / LC80Plus, the pressure sensor 745 can be a CY-YB-200 strain gauge pressure sensor, both motor 1 749 and motor 2 9 can be DT-D02, both electro-hydraulic actuator 1 71 and electro-hydraulic actuator 2 751 can be DYZW integral straight micro electro-hydraulic actuators, and the laser sensor 755 can be a WH-LRF laser rangefinder. The microcontroller 2 controls the operation of the laser cutting head 6, electro-hydraulic actuator 1 71, pressure sensor 745, motor 1 749, electro-hydraulic actuator 2 751, motor 2 9, and laser sensor 755 using methods commonly used in the prior art.
