[0020] Beneficial Effects

[0021] The present invention provides a CNC turret punch press for producing aluminum veneer. Compared with the prior art, it has the following beneficial effects:

[0022] (1) The CNC turret punch press for aluminum veneer production can install a variety of commonly used punch heads on the mold selection mechanism in advance through the cooperation between the connecting column, the mold selection mechanism, the servo motor and the toothed belt. The servo motor is started to drive the mold selection mechanism to rotate, and the required punch head on the mold selection mechanism is rotated to the far right so that it is located directly under the hydraulic cylinder. This can achieve rapid switching of the punch head of the required shape and easily cope with the diverse aluminum veneer processing needs.

[0023] (2) The CNC turret punch press for aluminum single plate production cooperates with each other among the bearing column assembly, the air charging mechanism, the air storage mechanism, the spring, the functional ring and the hydraulic cylinder. When the hydraulic cylinder moves downward to press the bearing column assembly downward, the air charging mechanism and the air storage mechanism are driven downward at the same time. When the air charging mechanism is driven downward, the piston rod and the piston move downward along the inside of the hollow cylinder, and the external gas is sucked into the upper part of the inner cavity of the hollow cylinder through the upper air inlet pipe. At the same time, the gas in the lower part of the inner cavity of the hollow cylinder is pushed into the air storage box through the exhaust elbow. When the punch head completes the punching, the hydraulic cylinder moves upward. Under the elastic action of the spring, the bearing column assembly moves upward accordingly. The air charging mechanism and the air storage mechanism are driven upward at the same time. When the air charging mechanism is driven upward, the piston rod and the piston move downward along the inner part of the hollow cylinder. The L-shaped rod moves upward, and the external gas is sucked into the lower part of the inner cavity of the hollow cylinder through the lower air inlet pipe, and the gas in the upper part of the inner cavity of the hollow cylinder is pushed into the gas box through the exhaust pipe. Since the piston rod drives the L-shaped rod to move together, the L-shaped rod passes through the lower opening during the downward and upward movement, and seals the gas box. As the gas in the gas box increases, the air pressure increases until the bottom of the L-shaped rod is separated from the lower opening, and the high-pressure gas in the gas box enters the confluence cavity through the lower opening and the air guide pipe, and is finally discharged through various blowing holes. It can be automatically blown to the surface of the stamping head and the lower aluminum veneer without the help of an external air pump, and the metal chips adhered to the surface of the stamping head and the lower aluminum veneer can be blown away in time to avoid affecting the subsequent stamping effect, thereby realizing the integrated operation of stamping and blowing.

[0024] (3) The CNC turret punch press for aluminum single plate production can flexibly remove the punch head from the bearing column through the mutual cooperation between the bearing column, bolts, protrusions and punch head, and replace the punch head with the required shape, which can cope with various complex and changeable processing requirements and enhance the adaptability and flexibility of the punch press.

[0025] (4) The CNC turret punch press for aluminum single plate production, through the mutual cooperation between the gas storage box, L-shaped rod, air guide tube and the port, can simultaneously drive the inflation mechanism to fill the gas into the gas storage box as the bearing column assembly and the punch head move up and down during the punching process. As the gas is continuously injected, the pressure in the gas storage box gradually increases to form high-pressure gas. This process not only ensures sufficient gas supply, but also improves the strength and effect of blowing by increasing the pressure, thereby achieving effective blowing and cleaning of the surface of the punch head.

The hollow cylinder 781 is fixedly connected to the bottom of the pressure plate 752. An air inlet pipe 784 is fixedly provided at the upper and lower parts of one side of the hollow cylinder 781 close to the bearing column 751. An air inlet valve 785 is fixedly provided in the middle of the two air inlet pipes 784. An exhaust pipe 786 is fixedly provided at the upper part of the side of the hollow cylinder 781 away from the air inlet pipe 784. A first exhaust valve 787 is fixedly provided in the middle of the exhaust pipe 786. An exhaust elbow 788 is fixedly provided at the lower part of the side of the hollow cylinder 781 away from the air inlet pipe 784. A second exhaust valve 789 is fixedly provided in the middle of the exhaust elbow 788. The air storage mechanism 79 includes an air storage box 791. The air storage box 791 is fixedly penetrated through the upper part of the corresponding limiting groove 74. The upper and lower parts of the air storage box 791 are provided with through openings, and the inner wall of the through opening is fixedly provided with a sealing ring.An L-shaped rod 792 slides through the upper opening, the top of the L-shaped rod 792 is fixedly connected to the upper part of the piston rod 783, the bottom of the air storage box 791 is fixedly connected to an air guide pipe 793, the bottom of the air guide pipe 793 is fixedly connected to the side wall of the functional ring 711, and the exhaust pipe 786 and the exhaust elbow 788 are both fixedly connected to the air storage box 791.

[0052] Through the cooperation among the bearing column assembly 75, the inflation mechanism 78, the gas storage mechanism 79, the spring 710, the functional ring 711 and the hydraulic cylinder 13, when the hydraulic cylinder 13 moves downward to press the bearing column assembly 75 downward, the inflation mechanism 78 and the gas storage mechanism 79 are driven downward at the same time. When the inflation mechanism 78 is driven downward, the piston rod 783 and the piston 782 move downward along the inside of the hollow cylinder 781, and the external gas is sucked into the upper part of the inner cavity of the hollow cylinder 781 through the upper air inlet pipe 784, and the gas in the lower part of the inner cavity of the hollow cylinder 781 is pushed into the gas storage box 791 through the exhaust elbow 788. After the stamping is completed, the hydraulic cylinder 13 moves upward. Under the elastic action of the spring 710, the bearing column assembly 75 moves upward accordingly, and the inflation mechanism 78 and the gas storage mechanism 79 are driven upward at the same time. During the upward driving of the inflation mechanism 78, the piston rod 783 and the piston 782 move upward along the inside of the hollow cylinder 781, and the external gas is sucked into the lower part of the inner cavity of the hollow cylinder 781 through the lower air inlet pipe 784. At the same time, the gas in the upper part of the inner cavity of the hollow cylinder 781 is pushed into the gas storage box 791 through the exhaust pipe 786. Since the piston rod 783 drives the L-shaped rod 792 to move together, the L-shaped rod 792 passes through the step of the lower opening during the downward and upward movement. The gas box 791 is sealed. As the gas in the gas box 791 increases, the gas pressure increases until the bottom of the L-shaped rod 792 is separated from the lower port. The high-pressure gas in the gas box 791 enters the confluence cavity 712 through the lower port and the air guide pipe 793, and is finally discharged through the blowing holes 713, automatically blowing to the surface of the punch head 77 and the lower aluminum single plate, and blowing away the metal chips adhered to the surface of the punch head 77 and the lower aluminum single plate in time to avoid affecting the subsequent stamping effect, thereby realizing the integrated operation of stamping and blowing. Through the cooperation between the bearing column 751, the bolt 753, the protrusion 76 and the punch head 77, the punch head can be 77 can be flexibly disassembled from the supporting column 751 and replaced with a punch head 77 of a required shape, which can cope with various complex and changeable processing requirements and enhance the adaptability and flexibility of the punch press. Through the cooperation between the gas storage box 791, the L-shaped rod 792, the air guide tube 793 and the port, as the supporting column assembly 75 and the punch head 77 move up and down during the stamping process, the inflation mechanism 78 can be driven to fill the gas storage box 791 with gas at the same time. As the gas is continuously injected, the pressure in the gas storage box 791 gradually increases to form high-pressure gas. This process not only ensures an adequate supply of gas, but also enhances the strength and effect of the purge through pressurization.

[0053] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0054] When in use, a variety of commonly used punching heads 77 are pre-installed at the bottom of each bearing column assembly 75, and controlled by the intelligent console 4, the servo motor 9 is started to drive the mold selection mechanism 7 to rotate, and the punching head 77 required on the mold selection mechanism 7 is rotated to the far right so that it is located directly below the hydraulic cylinder 13, and then the feeding mechanism 3 is operated to transport the aluminum single plate to be processed on the workbench mechanism 2 to the bottom of the mold selection mechanism 7, wherein the feeding mechanism 3 is mainly composed of a cross module, which belongs to the prior art well known to those skilled in the art, and is usually composed of two mutually perpendicular linear slides, which are driven by a motor to achieve precision in the X-axis and Y-axis directions. The feeding mechanism 3 transports the portion of the aluminum sheet to be punched to the right below the rightmost punching head 77, and then the hydraulic cylinder 13 works to press the bearing column assembly 75 and the punching head 77 downward, and the punching head 77 is used to punch and carve holes in the aluminum sheet. During the downward movement of the bearing column assembly 75, the air charging mechanism 78 and the air storage mechanism 79 are driven downward at the same time. During the downward driving of the air charging mechanism 78, the piston rod 783 and the piston 782 move downward along the inside of the hollow cylinder 781. During the process, the external gas is sucked into the upper part of the inner cavity of the hollow cylinder 781 through the upper air inlet pipe 784, and at the same time, the lower part of the inner cavity of the hollow cylinder 781 is sucked into the lower part of the inner cavity of the hollow cylinder 781 through the exhaust elbow 788. The gas is pushed into the gas storage box 791. When the punch head 77 completes the punching, the hydraulic cylinder 13 moves upward. Under the elastic action of the spring 710, the support column assembly 75 moves upward accordingly, and the inflation mechanism 78 and the gas storage mechanism 79 are driven upward at the same time. During the upward driving of the inflation mechanism 78, the piston rod 783 and the piston 782 move upward along the inside of the hollow cylinder 781. During the process, the external gas is sucked into the lower part of the inner cavity of the hollow cylinder 781 through the lower air inlet pipe 784, and the gas in the upper part of the inner cavity of the hollow cylinder 781 is pushed into the gas storage box 791 through the exhaust pipe 786. Since the piston rod 783 drives the L-shaped rod 792 to move together, the L-shaped rod 792 moves downward. During the process of moving down and up, the gas box 791 is sealed at the stage of passing through the lower opening. As the gas in the gas box 791 increases, the air pressure increases until the bottom of the L-shaped rod 792 separates from the lower opening. The high-pressure gas in the gas box 791 enters the confluence cavity 712 through the lower opening and the air guide pipe 793, and is finally discharged through the blowing holes 713, automatically blowing onto the surface of the punch head 77 and the lower aluminum plate, and blowing away the metal chips adhered to the surface of the punch head 77 and the lower aluminum plate in time, thereby realizing the integrated operation of punching and blowing. The blowing holes 713 on the inner wall of the functional ring 711 are designed to be inclined downward to guide the gas discharge downward.
