[0002] With the development of the stamping industry, various stamping equipment has been widely used in industrial production. However, these devices still have some significant problems in actual use. Currently, stamping equipment on the market usually requires manual die changing, which is cumbersome and time-consuming, greatly affecting production efficiency. In addition, when changing dies, operators need to frequently enter the equipment for manual operation, which not only increases the labor intensity of operators but also poses certain safety risks.

[0003] To improve performance, some manufacturers have attempted to increase automation by adding automatic mold-changing devices. However, such improvements often lead to increased equipment complexity, higher costs, and greater maintenance difficulties, resulting in poor overall system stability. Meanwhile, patent CN117181882B, for example, reduces friction through pre-positioning components and ball bearings, improving mold installation accuracy and disassembly efficiency. While this design simplifies the mold-changing process to some extent, it relies on multiple pre-positioning and positioning components, making the equipment structure more complex and increasing maintenance difficulty. Furthermore, ball bearings are prone to wear over long-term use, affecting the long-term stability of the equipment. Therefore, this case arose from in-depth research into these issues.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, the quick-change device for stamping dies of this utility model includes a frame 1, a sliding guide rail 2, a die mounting platform 3, a quick-locking mechanism 4, a drive motor 5, a transmission mechanism 6, a controller 7, an operation panel 8, a locking pin 9, a drive cylinder 10, a connecting plate 11, guide rollers 12, positioning pins 13, positioning holes 14, and sensors 15, among other main components. The specific structure, installation steps, operating principle, and practical application scenarios of this quick-change device for stamping dies will be described in detail below.

[0022] First, the frame 1 serves as the foundation support for the entire device, used to support and secure all other components. The frame 1 is constructed of high-strength steel, providing excellent stability and durability. Two parallel sliding guide rails 2 are mounted on the upper part of the frame 1. These guide rails 2 are made of precision-machined stainless steel with a hardened surface treatment to reduce friction and extend service life. Multiple guide rollers 12 are mounted on the sliding guide rails 2, contacting them via bearings and allowing them to slide freely along the rails. The design of the guide rollers 12 not only reduces friction between the mold mounting platform 3 and the sliding guide rails 2 but also improves the accuracy and stability of the sliding motion.

[0023] The mold mounting platform 3 is a flat plate structure made of aluminum alloy, featuring lightweight and high strength. Multiple guide grooves are provided on both sides of the mold mounting platform 3, which match the guide rollers 12 on the sliding guide rail 2, allowing for smooth movement along the sliding guide rail 2. Multiple quick-locking mechanisms 4 are provided on the upper surface of the mold mounting platform 3 for quickly fixing and unlocking the mold. Each quick-locking mechanism 4 includes a locking pin 9 and a drive cylinder 10. The locking pin 9 is connected to the piston rod of the drive cylinder 10 via a connecting plate 11. The drive cylinder 10 is fixed to the bottom of the mold mounting platform 3; the extension and retraction of its piston rod moves the connecting plate 11 and the locking pin 9, achieving mold locking and unlocking. The head of the locking pin 9 is designed with a tapered structure, which can tightly fit with the locking holes on the mold, ensuring the stability and safety of the mold.

[0024] To enable rapid movement of the mold mounting platform 3, a power drive unit is also provided on one side of the frame 1. This power drive unit includes a drive motor 5 and a transmission mechanism 6. The drive motor 5 is a servo motor, characterized by high precision and high response speed. The transmission mechanism 6 uses a linear screw module. When the drive motor 5 starts, the screw of the linear screw module engages with the threaded connection of the mold mounting platform 3, causing the mold mounting platform 3 to move rapidly along the sliding guide rail 2. This transmission mechanism 6 design ensures the moving speed and positional accuracy of the mold mounting platform 3, improving the efficiency and reliability of mold replacement.

[0025] A control device is also installed on one side of the frame 1, including a controller 7 and an operation panel 8. The controller 7 uses a PLC (Programmable Logic Controller), which can receive and process various signals to achieve precise control of the drive motor 5 and the quick-locking mechanism 4. The operation panel 8 is equipped with multiple buttons and a display screen. Operators can input commands through the operation panel 8 to control the start and stop of the drive motor 5 and the locking and unlocking of the quick-locking mechanism 4. The controller 7 is electrically connected to the drive motor 5 and the drive cylinder 10, and can adjust the working status of the drive motor 5 and the drive cylinder 10 in real time according to the input signals of the operation panel 8 and the detection signals of the sensor 15.

[0026] To further improve the accuracy and safety of mold changing, the control device also includes multiple sensors 15. Sensors 15 include position sensors and status sensors. The position sensors are mounted at both ends of the sliding guide rail 2 to detect the movement position of the mold mounting platform 3. The status sensors are mounted near the quick-locking mechanism 4 to detect the locking status of the locking pin 9. The controller 7 determines whether the mold mounting platform 3 has reached the predetermined position based on the signals from the position sensors, and determines whether the locking pin 9 is correctly locked or unlocked based on the signals from the status sensors. The design of these sensors 15 enables the control device to monitor and control the entire mold changing process in real time, ensuring the accuracy and safety of each step.

[0027] Multiple locating pins 13 are also provided on the upper surface of the mold mounting platform 3, and the locating pins 13 correspond to the locating holes 14 on the frame 1. When the mold mounting platform 3 moves to the predetermined position, the locating pins 13 automatically insert into the locating holes 14, thereby ensuring the precise positioning of the mold mounting platform 3. The design of the locating pins 13 and locating holes 14 not only improves the positioning accuracy of mold replacement, but also reduces the adjustment time for operators and improves production efficiency.

[0028] The following section details the operating principle and procedures of this quick-change die changing device for stamping, using a specific practical application scenario. Suppose a stamping workshop needs to frequently change dies of different specifications. Traditional methods require operators to manually adjust and fix the dies, which is time-consuming, labor-intensive, and poses safety hazards. Using the quick-change die changing device of this invention can significantly improve the efficiency and safety of die changing.

[0029] The operator first inputs a mold replacement command through the control panel 8. Upon receiving the command, the controller 7 first controls the piston rod of the drive cylinder 10 to retract, causing the locking pin 9 to disengage from the locking hole on the mold, thus unlocking the mold. Then, the controller 7 starts the drive motor 5, which, through the transmission mechanism 6, moves the mold mounting platform 3 along the sliding guide rail 2 towards the mold replacement area. During the movement, the position sensor 15 monitors the position of the mold mounting platform 3 in real time and sends a signal back to the controller 7. When the mold mounting platform 3 reaches the predetermined position, the position sensor 15 sends a signal, and the controller 7 immediately stops the drive motor 5.

[0030] Next, the operator places the new mold on the mold mounting platform 3. Using visual alignment or a positioning tool, the locking hole on the mold is aligned with the locking pin 9. Then, the operator inputs the mold-locking command through the control panel 8. Upon receiving the command, the controller 7 controls the piston rod of the drive cylinder 10 to extend, causing the locking pin 9 to insert into the locking hole of the mold, achieving rapid mold fixing. The status sensor 15 monitors the locking status of the locking pin 9 in real time and feeds the signal back to the controller 7. When the locking pin 9 correctly locks the mold, the status sensor 15 sends a signal, and the controller 7 confirms that the locking status is good.

[0031] Finally, the operator inputs a command via the control panel 8 to move the mold mounting platform 3 to the working position of the stamping machine. Upon receiving the command, the controller 7 restarts the drive motor 5, which, through the transmission mechanism 6, moves the mold mounting platform 3 along the sliding guide rail 2 to the working position of the stamping machine. During the movement, the position sensor 15 continues to monitor the position of the mold mounting platform 3 in real time to ensure it accurately reaches the predetermined position. When the mold mounting platform 3 reaches the working position of the stamping machine, the position sensor 15 sends a signal, and the controller 7 stops the drive motor 5. At this time, the operator can confirm the position and locking status of the mold mounting platform 3 through the display screen of the control panel 8 to ensure that the mold is installed correctly.

[0032] To further improve the efficiency and accuracy of mold changing, the device can also be equipped with an automatic identification system. The automatic identification system includes a camera and an image processing unit. The camera is mounted above the stamping machine and can capture real-time images of the mold on the mold mounting platform 3. The image processing unit is connected to the controller 7 and can automatically identify the mold's specifications and position based on the captured images, feeding the identification results back to the controller 7. The operator only needs to input the mold's specifications through the operation panel 8, and the controller 7 can automatically adjust the position and locking status of the mold mounting platform 3, achieving rapid mold changing and positioning.

[0033] In addition, the device can be equipped with a fault detection and alarm system. The fault detection system includes multiple sensors and alarms. The sensors are installed at various key locations and can monitor the operating status of the device in real time. When a fault is detected, the sensor sends a signal to the controller 7. The controller 7 controls the drive motor 5 and drive cylinder 10 to stop operating according to the fault type, and issues an alarm signal through the alarm to remind the operator to handle the fault in a timely manner and ensure the normal operation of the device.

[0034] In summary, the quick-change stamping die device of this invention enables rapid movement of the die mounting platform 3 via a sliding guide rail 2 and a power drive device, and achieves rapid fixing and unlocking of the die via multiple quick-locking mechanisms 4. The control device makes operation more intelligent, reduces the labor intensity of operators, and improves production efficiency and safety. The guide rollers 12 and positioning pins 13 improve sliding accuracy and stability, ensuring the reliability and consistency of die replacement. This device is widely used in various stamping workshops, significantly improving the efficiency and accuracy of die replacement, reducing production costs, and enhancing production safety.
