[0026] The plate is placed in the plate storage box on the fixed table, and the plate is placed in the plate storage box on the fixed table. After the plate is placed, the limiting plates on the four sides of the plate storage box are moved in the slide groove by adjusting the adjustment component to center the plate. After the plate is centered, the movable platform is driven by the guide sliding action of the guide rod to drive the lower mold to move to the bottom of the upper mold.

[0051] The exhaust assembly includes a booster fan 35 fixed to the upper end surface of the stamping machine body 1 by bolts. The exhaust port of the booster fan 35 is connected to the upper end of the hollow turntable 24 through a connecting air pipe 34 for rotating. It is used to input high-pressure airflow into the hollow turntable 24, while ensuring that the air pipe 34 will not be driven to rotate synchronously when the hollow turntable 24 rotates.

[0052] The upper end surface of the movable seat 6 surrounds the outside of the lower mold 4 and is vertically connected to multiple suction heads 37, and a collection box 38 is fixed to the outside of the connecting rod. The upper end of the collection box 38 is open, and a sealing cover is provided at the opening. The sealing cover and the movable seat 6 are connected through a suction pipe 40. The lower end of the collection box 38 is connected to the exhaust fan 39, and a dustproof net is provided at the exhaust port of the exhaust fan 39. By opening the sealing cover, the impurities and dust stored in the collection box 38 can be dumped. The exhaust fan 39 is connected to the collection box 38 to collect debris and dust generated during the stamping process.

[0053] Beneficial effect: efficient and automatic loading and unloading. Through the coordinated operation of the mobile storage cart 9, the plate storage box 17, the hollow rotary table 24, the suction cup 26 and the exhaust component, the plate can be automatically taken from the plate storage box 17 and loaded to the lower mold 4. After stamping and forming, it can be automatically unloaded to the mobile storage cart 9 for storage, replacing repeated manual picking, greatly improving processing efficiency.

[0054] Precise plate positioning: with the help of the adjustment component, the limit plate 19 is driven to move in the slide 18, and the displacement of the limit plate 19 is accurately controlled with the help of the scale 22 to ensure that the plate is placed in the center of the plate storage box 17, providing a precise initial position for subsequent stamping and forming, and ensuring the quality of the formed parts.

[0055] The mold is automatically cleaned by using the exhaust component to input high-pressure airflow into the hollow rotary table 24, which is discharged through the air hole 36 to effectively clean the lower mold 4 and the upper mold 3. At the same time, the collection system composed of the exhaust fan 39 and the collection box 38 is used to absorb and store the debris and dust generated by cleaning, avoiding the tedious and inefficient manual cleaning, and further improving production efficiency and molded part quality.

[0056] Structural installation and connection details, the stamping machine body 1 and the core components are installed, and the hydraulic cylinder 2 is firmly assembled on the upper end of the stamping machine body 1 to ensure that its push rod is vertically downward and accurately docked with the upper mold 3, so that the upper mold 3 can move downward smoothly under the drive of the hydraulic cylinder 2 to stamp the plate in the lower mold 4. The guide rod 5 is symmetrically installed at the front opening of the stamping machine body 1. Its smooth rod body ensures that the moving seat 6 can slide smoothly. The moving seat 6 and the lower mold 4 are connected with detachable connectors such as bolts, which is convenient for replacement and maintenance of the lower mold 4. The hydraulic push rod 2 7 is embedded in the left side of the stamping machine body 1. Its push rod is firmly connected to the moving seat 6 through a rigid connecting rod, providing a stable driving force for the lateral movement of the moving seat 6, so that the lower mold 4 can be accurately moved to the bottom of the upper mold 3 for stamping operations.

[0057] The mobile storage cart 9 is assembled with the fixed platform 16. The mobile storage cart 9 is made of high-strength steel as a whole and has sufficient carrying capacity. The universal wheels 14 at the four corners of the lower end are selected with a brake function, which is convenient for moving and fixing the position in the positioning track 15. The positioning track 15 is firmly fixed to the ground or work surface and precisely corresponds to the opening position of the stamping machine body 1, ensuring that the mobile storage cart 9 can be smoothly pushed into the interior of the stamping machine body 1. The upper end plane of the fixed platform 16 is finely processed to provide a stable installation foundation for the plate storage box 17.

[0058] The plate storage box 17 adopts a box structure with an upward opening, and a slide groove 18 extending toward the middle is processed on the four sides of the bottom wall. The inner surface of the slide groove 18 is smooth, and the limit plate 19 is matched and slidably connected with it to ensure that the limit plate 19 can move smoothly to adjust the position. The limit plate 19 can be driven to move back and forth in the slide groove 18 by rotating the threaded adjustment rod 21 in the adjustment component. The scale 22 is made of metal and is firmly welded to the upper end of the limit plate 19, and ensures that one end thereof is flush with the inner wall of the limit plate 19, so as to facilitate intuitive reading of the moving distance of the limit plate 19 and realize accurate centering of the plate.

[0059] The driving motor 23 is connected to the hollow rotating platform 24. The driving motor 23 is a servo motor. The hollow rotating platform 24 has a cavity structure in the middle. The suction cup 26 is made of rubber material with high adsorption force, which can fit closely to the surface of the plate and cooperate with the vacuum component to achieve firm adsorption and rapid release of the plate.

[0060] When the servo motor 31 in the vacuum assembly is working, it can drive the reel 32 to rotate, realize the automatic reeling and loosening of the hose 33, and adapt to the movement requirements of the suction cup 26 in different positions. The automatic exhaust valve 29 is installed on the outside of the hard tube 28 to control the discharge of gas and ensure the precise switching of the vacuum and exhaust processes.

[0061] The suction head 37 adopts a tubular structure set vertically upward, and the collection box 38 adopts a closed structure. Its lower end is connected to the suction port of the exhaust fan 39. A dustproof net is installed at the suction port of the exhaust fan 39 to prevent large particles of impurities from being sucked into the fan and damaging the equipment. The entire collection system can effectively absorb the debris and dust generated during the stamping process, keep the working environment clean, and reduce the adverse effects of dust on equipment operation.

[0062] This device is equipped with a centralized control system and uses PLC as the core control unit, which is responsible for the automated control and coordination of the entire stamping process.

[0063] The control system also includes a human-machine interface connected to the PLC. Operators can use the HMI to perform operations such as parameter setting, start / stop control, and fault alarm viewing, allowing them to intuitively and conveniently control the operation of the entire device.

[0064] Workflow and usage steps, workflow overview, the workflow of this distribution cabinet door stamping rapid prototyping device covers the links of sheet material pre-storage, automatic sheet material loading, stamping and forming, automatic unloading and mold cleaning. Each link is closely connected with a high degree of automation. Under the coordinated command of the PLC control system, efficient and high-quality continuous stamping and forming production of distribution cabinet doors is achieved.

[0065] First, the cut sheets are stored in the sheet storage box 17, and the limit plate 19 is adjusted to the center by the adjustment component; then the suction cup 26 on the hollow rotary table 24 adsorbs the sheet with the cooperation of the exhaust component and transfers it to the lower mold 4 under the upper mold 3; then the hydraulic cylinder 2 drives the upper mold 3 to move downward to complete the stamping and forming; after forming, the suction cup 26 adsorbs the molded part again and transfers it to the mobile storage vehicle 9; finally, the exhaust component works to clean the mold, and the collection system absorbs the debris and dust generated by the cleaning, preparing for the next round of stamping and forming cycle.

[0066] Detailed usage steps: manually push the universal wheels 14 on both sides of the mobile storage cart 9 into the two positioning tracks 15 respectively, so that the mobile storage cart 9 enters the opening of the stamping machine body 1, and when the mobile storage cart 9 moves in, it drives the iron block 13 on the connecting seat 12 to be inserted into the slot 10 and contact the electromagnet 11. The electromagnet 11 is energized to adsorb the iron block 13, so that the mobile storage cart 9 can be directional moved to the opening of the stamping machine body 1 and fixed, which is convenient for unloading and storing the formed door panels;

[0067] The plates are pre-stored and the cut plates are stacked and placed in the plate storage box 17 on the fixed table 16. After the plates are placed, according to the size of the plates, the threaded adjustment rod 21 is rotated to screw the inner thread of the nut 20 in and out, and the four limit plates 19 in the plate storage box 17 are pushed to move in the slide 18. The adjustment size is determined by referring to the display scale of the scale 22 to ensure the accuracy of the adjustment. The four limit plates 19 are adjusted to center the plates, ensuring that each layer of plates is neatly stacked and tightly fitted with the limit plates 19 on all sides to prevent the plates from shifting or tipping over during storage and retrieval.

[0068] Start the automatic stamping and forming cycle. After the sheet is centered, the hydraulic push rod 2 7 is used to push the movable seat 6. Under the guiding sliding action of the guide rod 5, the lower mold 4 is driven to move to the bottom of the upper mold 3. At the same time, the hollow rotating table 24 is driven by the driving motor 23 to rotate to the upper middle of the sheet storage box 17, and the hydraulic push rod 1 25 is used to push the suction cup 26 downward to contact the sheet. After contact, the air is extracted by the vacuum pump 27. At the same time, the air between the suction cup 26 and the sheet is sucked out by the mutual communication between the vacuum pump 27, the hard pipe 28, the automatic exhaust valve 29, the winding drum 32, the hose 33 and the suction cup 26, so that the adsorption and fixation of the sheet are achieved.

[0069] After the sheet is adsorbed, the hydraulic push rod 25 works to move the sheet to the top. While the suction cup 26 moves, the servo motor 31 works to drive the reel 32 to rotate, and the hose 33 is wound and released. It is adaptively wound and released as the suction cup 26 moves, and the hollow rotary table 24 and the suction cup 26 are driven by the drive motor 23 to rotate to the top of the lower mold 4. The hydraulic push rod 25 is driven to move the suction cup 26 downward to place the sheet into the lower mold 4. The suction cup 26 is separated from the sheet by the automatic exhaust valve 29. After separation, the hydraulic push rod 25 and the drive motor 23 are driven to move the suction cup 26 upward and rotate to the side of the stamping machine body 1, thereby realizing the automatic and uninterrupted sheet material loading from the sheet material storage box 17 to the lower mold 4.

[0070] After the loading is completed, the upper mold 3 is pushed down by the hydraulic cylinder 2 to stamp and form the sheet in the lower mold 4. After stamping and forming, the upper mold 3 moves back to its original position, and the driving motor 23 and the hydraulic push rod 1 25 are driven again to move the suction cup 26 to the top of the upper mold 3, and make the suction cup 26 fit the formed sheet, and cooperate with the air pump 27 to adsorb. After the adsorption is completed, the hydraulic push rod 1 25 is driven to make the suction cup 26 drive the formed sheet to move to the top of the upper mold 3, and then cooperate with the hydraulic push rod 2 7 to drive the lower mold 4 to move to the far left, so as to cooperate with the hydraulic push rod 1 25 and the air pump 27 to move the adsorbed formed sheet downward and stacked and put it into the mobile storage car 9 for storage, thereby realizing the automatic unloading of the formed sheet. Compared with the existing technology, it realizes the automatic loading and unloading of sheets and formed parts and improves the processing efficiency;

[0071] After the forming material is discharged into the mobile storage vehicle 9, the hollow rotary table 24 is positioned between the lower mold 4 and the upper mold 3 by driving the driving motor 23 and the hydraulic push rod 25, and the high-pressure airflow is discharged into the hollow rotary table 24 through the air pipe 34 in cooperation with the booster fan 35, and discharged through the air hole 36 to achieve the cleaning of the lower mold 4 and the upper mold 3. During the cleaning, the cleaned debris and dust are exhausted by the exhaust fan 39 at the same time, and the exhaust fan 39, the collection box 38, the suction pipe 40, the movable seat 6, and the suction head 37 are interconnected to suck the debris and dust into the collection box 38 for storage, thereby ensuring the cleanliness of the mold, improving the quality of the processed molded parts, avoiding the low efficiency of manual cleaning, and further improving the processing efficiency.

[0072] After the work is finished and the production task is completed, the cover of the collection box 38 is opened to clean the debris and dust stored inside to prevent clogging of the suction pipe 40 and affecting the subsequent collection effect.

[0073] Cut off the main power supply of the device and conduct a comprehensive inspection and maintenance of the equipment, including wiping the oil stains on the surface of each component, checking the tightness of key connection parts, adding lubricating oil to moving parts, etc., to ensure that the equipment can operate normally when it is started next time.

[0074] Conclusion: This distribution cabinet door stamping rapid prototyping device, through innovative structural design and intelligent control system, successfully realizes the automatic loading and unloading, automatic mold cleaning and automatic storage of molded parts in the distribution cabinet door stamping forming process, and effectively solves the problems of low loading and unloading efficiency, cumbersome manual mold cleaning and affecting the forming quality of traditional stamping forming equipment.
