Description

Technical Field

[0001] This invention relates to the field of electrical distribution cabinet stamping technology, specifically to a rapid stamping device for electrical distribution cabinet doors. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final stage equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in situations where the load is concentrated and there are more circuits. The cabinet doors of distribution cabinets need to be stamped during production.

[0003] When stamping the cabinet doors of electrical distribution cabinets, standard-sized sheet metal is placed on the lower die of the stamping machine. The upper die is then moved down by the machine to stamp the sheet metal in the lower die. During loading and unloading, workers need to repeatedly handle the sheet metal, which is time-consuming, labor-intensive, and inefficient. In addition, to ensure the quality of the stamped parts, impurities in the die need to be cleaned manually, which is also inefficient. Therefore, the normal production operation of the stamping equipment is hindered. We propose a rapid prototyping device for electrical distribution cabinet doors to solve this technical deficiency.

[0024] Three beneficial effects

[0025] Compared with the prior art, the present invention provides a rapid prototyping device for stamping distribution cabinet doors, which has the following advantages:

[0026] 1. This rapid prototyping device for power distribution cabinet doors pushes a mobile storage cart into the opening of the stamping machine, while simultaneously stacking cut sheet metal into the sheet metal storage box on the fixed platform. After placement, the limiting plates on the four sides of the sheet metal storage box are moved in the slide groove by adjusting the adjustment component to center the sheet metal. After the sheet metal is centered, the lower mold moves to below the upper mold by the guide sliding action of the guide rod through the set mobile platform. At the same time, the hollow rotary table is driven by the drive motor to rotate to the upper center of the sheet metal storage box, and the hydraulic push rod pushes the suction cup down to contact the sheet metal. After contact, the air extraction component works to extract air, so that the suction cup adsorbs the sheet metal and moves the sheet metal to the top. The drive motor drives the suction cup to rotate above the lower mold, and drives the suction cup down to place the sheet metal into the lower mold. The air extraction component exhausts air to separate the suction cup from the sheet metal. After separation, the suction cup is driven to move up and rotate to the side of the stamping machine, thus realizing automatic and uninterrupted sheet metal feeding.

[0027] After the material is loaded, the upper mold is pushed down by the hydraulic cylinder to stamp the sheet material in the lower mold. After stamping, the upper mold moves back to its original position, and the drive motor and hydraulic push rod 1 are driven again to move the suction cup above the upper mold and make the suction cup fit against the formed sheet material. The suction component is used to perform adsorption. After adsorption, the suction cup moves the formed sheet material above the upper mold. Then, the lower mold is moved to the leftmost position by the set moving platform. In this way, the hydraulic push rod 1 and the suction component work together to move the adsorbed formed sheet material down and stack it into the mobile storage cart for storage. This realizes the automatic unloading of the formed sheet material. Compared with the existing technology, it realizes the automatic loading and unloading of sheet material and formed parts, improving the processing efficiency.

[0028] 2. This rapid prototyping device for the cabinet door of the power distribution cabinet, through the exhaust component, after the stamping and blanking are completed, drives the hollow rotary table to be positioned between the lower mold and the upper mold. In conjunction with the exhaust component, high-pressure airflow is discharged into the hollow rotary table and discharged through the air hole, thereby cleaning the lower mold and the upper mold, ensuring the cleanliness of the mold, improving the quality of the processed parts, avoiding the low efficiency of manual cleaning, and further improving the processing efficiency.

A hydraulic push rod 7 is detachably installed and fixed inside the left side of the stamping machine body 1 by bolts. The push rod is connected and fixed to the moving seat 6 by a fixed connecting rod. When the moving seat 6 moves to the rightmost position, the lower mold 4 is exactly below the upper mold 3.

[0045] Other auxiliary structures include pads 8 fixed at the four corners of the upper surface of the stamping machine body 1, which fit against the lower surface of the moving seat 6, and serve as supports and positioning.

[0046] The device also includes a pair of positioning rails 15, which are fixed to the ground by bolts. The four corners of the lower end of the mobile storage vehicle 9 are equipped with casters 14, with the casters 14 on both sides located in the two positioning rails 15 respectively, which facilitates the stable movement and positioning of the mobile storage vehicle 9.

[0047] A pair of symmetrically distributed slots 10 are provided on the left and right sides of the front surface of the stamping machine body 1. An electromagnet 11 is fixed in the slot 10. A fixed iron block 13 is attracted to the surface of the electromagnet 11. A connecting seat 12 that is connected and fixed to the mobile storage vehicle 9 is connected to the surface of the iron block 13, so as to realize the quick fixing and release of the mobile storage vehicle 9.

[0048] The adjustment assembly includes a nut 20 fixed to the four outer walls of the plate storage box 17. The nut 20 is internally threaded with a threaded adjustment rod 21 that passes through the plate storage box 17 and is rotatably engaged with the limiting plate 19. By rotating the threaded adjustment rod 21, the limiting plate 19 can be driven to move along the slide 18 to adjust the position of the plate in the plate storage box 17.

[0049] A scale 22 is fixed vertically and horizontally on the upper surface of the limiting plate 19. One end of the scale 22 is flush with the inner wall of the limiting plate 19, which facilitates accurate reading of the movement distance of the limiting plate 19 and ensures that the plate is placed in the center.

[0050] The air extraction assembly consists of an air pump 27 fixed to the right side surface of the press body 1, a mounting base 30 fixed to the upper surface of the hollow rotary table 24, a servo motor 31 fixed to the front surface of the mounting base 30 by bolts, a take-up drum 32 connected to the output end of the servo motor 31, and a flexible hose 33 wound around the outside of the take-up drum 32 and passing through the hollow rotary table 24 and communicating with the suction cup 26. The air extraction port of the air pump 27 is rotatably connected to the center of the rear surface of the take-up drum 32 through a rigid tube 28. An automatic exhaust valve 29 is connected to the outer surface of the rigid tube 28.

[0051] The exhaust assembly includes a booster fan 35 that is bolted to the upper surface of the press body 1. The exhaust port of the booster fan 35 is rotatably connected to the upper end of the hollow rotary table 24 via a connecting air pipe 34. This connection is used to input high-pressure airflow into the hollow rotary table 24, while ensuring that the air pipe 34 does not rotate synchronously when the hollow rotary table 24 rotates.

[0052] Multiple suction heads 37 are vertically connected to the upper surface of the movable seat 6, surrounding the outer side of the lower mold 4. A collection box 38 is fixed to the outside of the connecting rod. The upper end of the collection box 38 is open and equipped with a cover. The cover is connected to the movable seat 6 via a suction pipe 40. The lower end of the collection box 38 is connected to an exhaust fan 39. The exhaust port of the exhaust fan 39 is equipped with a dustproof net. By opening the cover, the impurities and dust stored in the collection box 38 can be poured out. The exhaust fan 39 is connected to the collection box 38 to collect the debris and dust generated during the stamping process.

[0053] Beneficial effects: Highly efficient automatic loading and unloading. Through the coordinated operation of the mobile storage cart 9, the sheet storage box 17, the hollow rotary table 24, the suction cup 26, and the air extraction component, the sheet material is automatically picked up from the sheet storage box 17, loaded into the lower mold 4, and after stamping, it can be automatically unloaded into the mobile storage cart 9 for storage, replacing manual repeated handling and greatly improving processing efficiency.

[0054] Precise sheet positioning is achieved by using an adjustment component to drive the limiting plate 19 to move within the slide groove 18. The displacement of the limiting plate 19 is precisely controlled by a scale 22, ensuring that the sheet is placed in the center within the sheet storage box 17. This provides a precise initial position for subsequent stamping and ensures the quality of the formed parts.

[0055] The mold is automatically cleaned by using an exhaust assembly to input high-pressure airflow into the hollow rotary table 24 and discharge it through the air hole 36 to effectively clean the lower mold 4 and the upper mold 3. At the same time, the collection system consisting of an exhaust fan 39 and a collection box 38 is used to absorb and store the debris and dust generated during cleaning, avoiding the tediousness and inefficiency of manual cleaning and further improving production efficiency and the quality of molded parts.

[0056] Structural installation and connection details: Installation of the stamping machine body 1 and core components: The hydraulic cylinder 2 is securely mounted on the upper end of the stamping machine body 1, ensuring that its push rod is vertically downward and accurately aligned with the upper mold 3. This allows the upper mold 3 to move smoothly downward under the drive of the hydraulic cylinder 2 to stamp the sheet metal inside 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 by detachable connectors such as bolts, which facilitates the replacement and maintenance of the lower mold 4. The hydraulic push rod 7 is embedded inside 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 lower mold 3 directly below 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 and has sufficient load-bearing capacity. The four casters 14 at the bottom are of the model with braking function, which facilitates movement and fixation within the positioning rail 15. The positioning rail 15 is firmly fixed to the ground or workbench and corresponds precisely to the opening position of the stamping machine body 1, ensuring that the mobile storage cart 9 can be smoothly pushed into the stamping machine body 1. The upper surface of the fixed platform 16 is finely machined to provide a stable installation base for the sheet metal storage box 17.

[0058] The plate storage box 17 adopts an upward-facing box structure. The bottom wall of the box has four sides machined with grooves 18 extending towards the center. The inner surface of the grooves 18 is smooth. The limiting plate 19 is matched and slidably connected to it to ensure that the limiting plate 19 can move smoothly to adjust its position. The limiting plate 19 can be driven to move back and forth in the grooves 18 by rotating the threaded adjusting rod 21 in the adjustment component. The scale 22 is made of metal and is firmly welded to the upper end of the limiting plate 19, ensuring that one end of it is flush with the inner wall of the limiting plate 19, so as to intuitively read the movement distance of the limiting plate 19 and achieve precise centering of the plate.

[0059] The drive motor 23 is connected to the hollow rotary table 24. The drive motor 23 is a servo motor. The hollow rotary table 24 has a hollow cavity structure in the middle. The suction cup 26 is made of rubber with high adsorption force, which can closely adhere to the surface of the board. Together with the air extraction component, it can achieve firm adsorption and rapid release of the board.

[0060] When the servo motor 31 in the air extraction assembly is working, it can drive the winding drum 32 to rotate, realize the automatic winding and unwinding of the hose 33, adapt to the movement requirements of the suction cup 26 in different positions, and the automatic exhaust valve 29 is installed on the outside of the rigid tube 28 to control the gas discharge and ensure the precise switching between the air extraction and exhaust processes.

[0061] The suction head 37 adopts an upwardly vertically arranged tubular structure, 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, which uses a PLC as the core control unit to automate and coordinate the entire stamping process.

[0063] The control system also includes a human-machine interface connected to the PLC, allowing operators to perform parameter settings, start / stop control, and fault alarm viewing, thus intuitively and conveniently controlling the operation of the entire device.

[0064] Workflow and Usage Steps: Workflow Overview: The workflow of this rapid prototyping device for power distribution cabinet doors includes pre-storage of sheet metal, automatic feeding of sheet metal, stamping, automatic unloading, and mold cleaning. Each step is closely connected and highly automated. Under the coordination and command of the PLC control system, it realizes efficient and high-quality continuous stamping production of power distribution cabinet doors.

[0065] First, the cut sheet metal is stored in the sheet metal storage box 17, and the limiting plate 19 is adjusted to be centered by adjusting the component. Then, the suction cup 26 on the hollow rotary table 24, with the help of the air extraction component, adsorbs the sheet metal and transfers it to the lower mold 4 below the upper mold 3. Then, the hydraulic cylinder 2 drives the upper mold 3 to move down to complete the stamping. After forming, the suction cup 26 adsorbs the formed 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 during cleaning, preparing for the next stamping cycle.

[0066] Detailed usage steps: Hold and 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. When the mobile storage cart 9 moves in, it drives the iron block 13 on the connecting seat 12 to insert into the slot 10 and contact the electromagnet 11. When the electromagnet 11 is energized, it attracts the iron block 13, so that the mobile storage cart 9 can be oriented to move into the opening of the stamping machine body 1 and be fixed, which facilitates the unloading and storage of the formed door panel.

[0067] The pre-stored boards are stacked into the board storage box 17 on the fixed platform 16 after being cut. After placement, the boards are adjusted according to their dimensions. By rotating the threaded adjustment rod 21 and screwing it in and out of the nut 20, the four limiting plates 19 inside the board storage box 17 are moved in the slide groove 18. The adjustment size is determined by referring to the scale of the ruler 22 to ensure the accuracy of the adjustment. The adjustment of the four limiting plates 19 centers the boards, ensuring that each layer of boards is neatly stacked and that the boards are tightly fitted to the limiting plates 19 on all sides, preventing displacement or tipping of the boards during storage and retrieval.

[0068] The automatic stamping and forming cycle is started. After the sheet is centered, the hydraulic push rod 27 pushes the moving seat 6 under the guidance of the guide rod 5, which moves the lower mold 4 to below the upper mold 3. At the same time, the drive motor 23 drives the hollow rotary table 24 to rotate to the middle above the sheet storage box 17. The hydraulic push rod 25 pushes the suction cup 26 down to contact the sheet. After contact, the air pump 27 works to extract air. The air pump 27, rigid pipe 28, automatic exhaust valve 29, winding drum 32, hose 33 and suction cup 26 are interconnected to extract the air between the suction cup 26 and the sheet, so that the sheet is adsorbed and fixed.

[0069] After the sheet material is adsorbed, the hydraulic push rod 25 moves the sheet material to the top. While the suction cup 26 moves, the servo motor 31 drives the winding drum 32 to rotate, winding and unwinding the hose 33. The winding and unwinding adapts to the movement of the suction cup 26. The drive motor 23 drives the hollow rotary table 24 and the suction cup 26 to rotate above the lower mold 4. The hydraulic push rod 25 is driven to move the suction cup 26 down and place the sheet material into the lower mold 4. The automatic exhaust valve 29 exhausts the air and separates the suction cup 26 from the sheet material. After separation, the hydraulic push rod 25 and the drive motor 23 are driven to move the suction cup 26 up and rotate it to the side of the stamping machine body 1, thereby realizing the automatic and uninterrupted feeding of the sheet material from the sheet material storage box 17 into the lower mold 4.

[0070] After the material is loaded, the upper mold 3 is pushed down by the hydraulic cylinder 2 to press the sheet material in the lower mold 4. After the stamping is completed, the upper mold 3 moves back to its original position and drives the drive motor 23 and the hydraulic push rod 25 to move the suction cup 26 above the upper mold 3 and make the suction cup 26 fit with the formed sheet material. The suction pump 27 works to perform adsorption. After adsorption is completed, the hydraulic push rod 25 is driven to move the suction cup 26 and the formed sheet material above the upper mold 3. Then, the lower mold 4 is moved to the leftmost position in conjunction with the hydraulic push rod 25 and the suction pump 27 to move the adsorbed formed sheet material down and stack it into the mobile storage cart 9 for storage. This realizes the automatic unloading of the formed sheet material. Compared with the existing technology, it realizes the automatic loading and unloading of sheet material and formed parts, improving the processing efficiency.

[0071] After the molded material is placed 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 drive motor 23 and the hydraulic push rod 25. With the help of the booster fan 35, high-pressure airflow is discharged into the hollow rotary table 24 through the air pipe 34 and discharged through the air hole 36, thereby cleaning the lower mold 4 and the upper mold 3. During cleaning, the debris and dust are extracted by the exhaust fan 39. At the same time, the debris and dust are sucked into the collection box 38 for storage by utilizing the interconnection between the exhaust fan 39, the collection box 38, the suction pipe 40, the moving seat 6, and the suction head 37. This ensures the cleanliness of the mold, improves the quality of the processed parts, avoids the low efficiency of manual cleaning, and further improves the processing efficiency.

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

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

[0074] In conclusion, this rapid prototyping device for distribution cabinet doors, through its innovative structural design and intelligent control system, successfully achieves automatic loading and unloading, automatic mold cleaning, and automatic storage of molded parts during the distribution cabinet door stamping process. It effectively solves the problems of low loading and unloading efficiency and tedious manual mold cleaning that affect molding quality inherent in traditional stamping equipment. Its efficient production process, precise sheet metal positioning, and stable molding quality give it significant technical advantages and application value in the field of distribution cabinet door production. It can meet the stringent requirements of modern manufacturing for production efficiency and product quality, and possesses broad market prospects and good economic benefits.
