Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of machining, and in particular to a high-precision die-cutting machine punch head. Background Technology
[0002] Die-cutting machines utilize steel blades to apply pressure to sheet metal, cutting it into specific shapes. They are widely used in printing and machining. In the prior art, utility model patent application number 202122585445.9 discloses a bidirectional feeding die-cutting machine, mainly composed of a cylinder and a die-cutting blade. During operation, the cylinder causes the piston rod to descend, bringing the die-cutting blade into contact with the sheet metal to complete the cutting. However, this design suffers from several problems. Since different die-cutting blades are used depending on the process requirements, the aforementioned prior art device only has one type of die-cutting blade, limiting its usability and making it inconvenient to use. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a high-precision die-cutting machine punch head that can be used with different types of die-cutting blade mechanisms as needed, which is convenient to use and highly practical.
[0004] This utility model relates to a high-precision die-cutting machine punching head, comprising a lifting frame and a three-jaw chuck; it also includes a lifting mechanism, a blade changing mechanism, and multiple die-cutting blade mechanisms. The three-jaw chuck is mounted on the lifting mechanism, which is used to raise and lower the three-jaw chuck. The multiple die-cutting blade mechanisms are of different types and are all mounted on the blade changing mechanism, which has the function of replacing the die-cutting blade mechanisms. The blade changing mechanism is mounted on the lifting frame, and the lifting mechanism is also mounted on the lifting frame. When die-cutting a sheet material, one die-cutting blade mechanism on the blade changing mechanism is mounted on the three-jaw chuck. Then, the lifting mechanism is opened, and the lifting mechanism lowers the connected die-cutting blade mechanism via the three-jaw chuck, thereby punching the sheet material. When it is necessary to change the die-cutting blade mechanism, the die-cutting blade mechanism on the three-jaw chuck is replaced via the blade changing mechanism. Because it has multiple different types of die-cutting blade mechanisms, and different types of die-cutting blade mechanisms can be replaced as needed, it is convenient to use and highly practical.
[0005] Preferably, the die-cutting mechanism includes a punching blade, an iron block, and a connecting shaft. The iron block is fixedly installed on the upper end of the punching blade, and the connecting shaft is fixedly installed on the upper end of the iron block. The punching blades on the multiple die-cutting mechanisms are all different. When punching the sheet metal, the iron block and connecting shaft on the corresponding die-cutting mechanism are moved to below the three-jaw chuck by the blade changing mechanism. Then, the three-jaw chuck is lowered by the lifting mechanism so that it clamps and fixes the connecting shaft below it. The sheet metal can then be punched by the punching blade below the three-jaw chuck. This facilitates the punching of the sheet metal.
[0006] Preferably, the lifting mechanism includes a hydraulic cylinder and a push rod. The hydraulic cylinder is fixedly installed on the upper end of the hoisting frame, and the push rod is slidably installed on the hoisting frame. The upper end of the push rod is connected to the output end of the hydraulic cylinder, and the three-jaw chuck is fixedly installed on the lower end of the push rod. When adjusting the height of the three-jaw chuck, the hydraulic cylinder is opened, and the hydraulic cylinder drives the push rod to rise and fall, thereby adjusting the height of the three-jaw chuck. When punching the sheet metal, the three-jaw chuck drives the connecting shaft, iron block and punching blade connected to it to fall when it descends. The punching blade contacts the sheet metal during the descent and punches the sheet metal.
[0007] Preferably, the tool changing mechanism includes a left-right moving mechanism, a stepper motor, a rotating shaft, multiple sets of connecting rods, and multiple sets of electromagnets. The left-right moving mechanism is mounted on a lifting frame, and the stepper motor is mounted on the left-right moving mechanism. The left-right moving mechanism is used to move the stepper motor left and right. A rotating shaft is provided at the output end of the stepper motor. Multiple sets of connecting rods are all fixedly mounted on the rotating shaft, and multiple sets of electromagnets are respectively fixedly mounted on the multiple sets of connecting rods. The multiple sets of electromagnets respectively attract and fix multiple sets of iron blocks. When changing the punching tool on the three-jaw chuck, the stepper motor is first turned on. The stepper motor drives the rotating shaft to rotate, and the rotating shaft drives the multiple sets of connecting rods to rotate, thereby causing the electromagnets not connected to iron blocks to rotate to the side closer to the three-jaw chuck. Then, by left-right moving... The actuator causes the stepper motor to drive the rotating shaft to move to the left. The rotating shaft drives the connecting rods and electromagnets to move to the left, causing the electromagnets not connected to the iron blocks to contact the iron blocks below the three-jaw chuck. Then, the electromagnets are opened, allowing them to attract and fix the iron blocks. Next, the three-jaw chuck is opened, and then the stepper motor is opened. The stepper motor drives the rotating shaft to rotate, which in turn drives multiple connecting rods to rotate. These connecting rods, through multiple electromagnets, cause multiple iron blocks to rotate, allowing the required punching blade to rotate to the bottom of the three-jaw chuck. The three-jaw chuck then clamps and fixes the connecting shaft below it. Finally, the electromagnets near the three-jaw chuck are closed, disengaging the corresponding electromagnets from the iron blocks they are connected to. This facilitates the replacement of punching blades on the three-jaw chuck.
[0008] Preferably, the left and right moving mechanism includes an electric slide rail and a sliding plate. The electric slide rail is fixedly installed on the hoisting frame, and the sliding plate is installed on the electric slide rail. The electric slide rail is used to move the sliding plate left and right. A stepper motor is fixedly installed at the lower end of the sliding plate. When the stepper motor moves left and right, the electric slide rail is opened, and the electric slide rail drives the sliding plate to move left and right. The sliding plate then drives the stepper motor to move left and right. This facilitates the left and right movement of 18.
[0009] Preferably, mounting plates are provided at both ends of the hoisting frame; this arrangement facilitates the connection between the hoisting frame and external devices.
[0010] Preferably, the hydraulic cylinder is equipped with a dust cover.
[0011] Compared with the prior art, the advantages of this utility model are: different types of die-cutting knife mechanisms can be replaced as needed, making it convenient to use and highly practical. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1
[0019] like Figures 1 to 5This utility model's high-precision die-cutting machine punching head includes a lifting frame 1, a three-jaw chuck 2, a lifting mechanism, a tool changing mechanism, and multiple die-cutting blade mechanisms. The three-jaw chuck 2 is mounted on the lifting mechanism, which is used to raise and lower the three-jaw chuck 2. The multiple die-cutting blade mechanisms are of different types and are all mounted on the tool changing mechanism, which has the function of replacing the die-cutting blade mechanisms. The tool changing mechanism is mounted on the lifting frame 1, and the lifting mechanism is mounted on the lifting frame 1. When die-cutting the sheet material, one die-cutting blade mechanism on the tool changing mechanism is mounted on the three-jaw chuck 2. Then, the lifting mechanism is opened, and the lifting mechanism lowers the die-cutting blade mechanism connected to the three-jaw chuck 2, thereby punching the sheet material. When it is necessary to change the die-cutting blade mechanism, the die-cutting blade mechanism on the three-jaw chuck 2 can be replaced through the tool changing mechanism. Because it is equipped with multiple different types of die-cutting blade mechanisms, and different types of die-cutting blade mechanisms can be replaced as needed, it is convenient to use and highly practical.
[0020] like Figure 3 and Figure 4 The die-cutting mechanism includes a punching blade 3, an iron block 4, and a connecting shaft 5. The iron block 4 is fixedly installed on the upper end of the punching blade 3, and the connecting shaft 5 is fixedly installed on the upper end of the iron block 4. The punching blades 3 on multiple die-cutting mechanisms are all different. When punching the sheet metal, the iron block 4 and the connecting shaft 5 on the corresponding die-cutting mechanism are moved to the underside of the three-jaw chuck 2 by the blade changing mechanism. Then, the three-jaw chuck 2 is lowered by the lifting mechanism so that the three-jaw chuck 2 clamps and fixes the connecting shaft 5 below it. The sheet metal can then be punched by the punching blade 3 below the three-jaw chuck 2. This facilitates the punching of the sheet metal.
[0021] like Figure 1 and Figure 4 The lifting mechanism includes a hydraulic cylinder 6 and a push rod 7. The hydraulic cylinder 6 is fixedly installed on the upper end of the hoisting frame 1, and the push rod 7 is slidably installed on the hoisting frame 1. The upper end of the push rod 7 is connected to the output end of the hydraulic cylinder 6, and the three-jaw chuck 2 is fixedly installed on the lower end of the push rod 7. When the height of the three-jaw chuck 2 is adjusted, the hydraulic cylinder 6 is opened, and the hydraulic cylinder 6 drives the push rod 7 to rise and fall, thereby adjusting the height of the three-jaw chuck 2. When punching the sheet metal, the three-jaw chuck 2 drives the connecting shaft 5, the iron block 4 and the punching blade 3 connected to it to descend when it descends. The punching blade 3 contacts the sheet metal during the descent and punches the sheet metal.
[0022] like Figure 3 and Figure 5The tool changing mechanism includes a left-right moving mechanism, a stepper motor 8, a rotating shaft 9, multiple sets of connecting rods 10, and multiple sets of electromagnets 11. The left-right moving mechanism is mounted on the lifting frame 1, and the stepper motor 8 is mounted on the left-right moving mechanism. The left-right moving mechanism is used to move the stepper motor 8 left and right. The output end of the stepper motor 8 is provided with a rotating shaft 9. The multiple sets of connecting rods 10 are all fixedly mounted on the rotating shaft 9, and the multiple sets of electromagnets 11 are respectively fixedly mounted on the multiple sets of connecting rods 10. The multiple sets of electromagnets 11 respectively attract and fix multiple sets of iron blocks 4. The stepper motor 8 is a motor with angle self-locking capability. When changing the punching blade 3 on the three-jaw chuck 2, the stepper motor 8 is first turned on. The stepper motor 8 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the multiple sets of connecting rods 10 to rotate, thereby causing the electromagnets 11 that are not connected to the iron blocks 4 to rotate to the side closer to the three-jaw chuck 2. Then, through The left-right movement mechanism causes the stepper motor 8 to drive the rotating shaft 9 to move to the left. The rotating shaft 9 drives the connecting rod 10 and the electromagnet 11 to move to the left, thereby making the electromagnet 11, which is not connected to the iron block 4, contact the iron block 4 below the three-jaw chuck 2. Then, the electromagnet 11 is opened, so that the electromagnet 11 attracts and fixes the iron block 4. Then, the three-jaw chuck 2 is opened, and then the stepper motor 8 is opened. The stepper motor 8 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives multiple connecting rods 10 to rotate. The multiple connecting rods 10 rotate multiple iron blocks 4 through multiple electromagnets 11, so that the required punching blade 3 is rotated to the bottom of the three-jaw chuck 2. Then, the three-jaw chuck 2 clamps and fixes the connecting shaft 5 below it. Then, the electromagnet 11 near the three-jaw chuck 2 is closed, so that the corresponding electromagnet 11 is disengaged from the iron block 4 it is connected to. This makes it convenient to change the punching blade 3 on the three-jaw chuck 2.
[0023] like Figure 3 The left and right moving mechanism includes an electric slide rail 12 and a sliding plate 13. The electric slide rail 12 is fixedly installed on the hoisting frame 1, and the sliding plate 13 is installed on the electric slide rail 12. The electric slide rail 12 is used to move the sliding plate 13 left and right. The stepper motor 8 is fixedly installed at the lower end of the sliding plate 13. When the stepper motor 8 is moved left and right, the electric slide rail 12 is opened, and the electric slide rail 12 drives the sliding plate 13 to move left and right. The sliding plate 13 then drives the stepper motor 8 to move left and right. This facilitates the left and right movement of 18.
[0024] Mounting plates 14 are provided at both ends of the hoisting frame 1; the above-mentioned configuration facilitates the connection between the hoisting frame 1 and external devices. Example 2
[0025] Based on Example 1, a dust cover is provided on the hydraulic cylinder 6.
