Description

Technical Field

[0001] This invention relates to the field of electrical distribution cabinet stamping technology, and more specifically, to a stamping apparatus for producing electrical distribution cabinets. Background Technology

[0002] Sheet metal stamping is an important step in the manufacturing process of distribution cabinets. During the production and processing of the distribution cabinet shell, the square shell sheet metal parts with flanges require stamping equipment. Its function is to form the metal sheet through molds and pressure, realizing the flange and punching processing of the metal sheet.

[0003] However, existing sheet metal stamping equipment for distribution cabinets cannot avoid material jamming, and sheet metal for distribution cabinets formed by pushing with a single push rod will cause deformation of the sheet metal during demolding.

[0004] To address the aforementioned issues, Chinese Patent Publication No. CN223571758U discloses a sheet metal stamping and forming equipment for a power distribution cabinet, comprising a base, a supporting vertical plate, and a top plate. Sheet metal forming lower molds are mounted on both ends of the top of the base via the supporting plates, and sheet metal forming cavities are provided within the lower molds. Fixed plate grooves are provided at the bottom corners of the sheet metal forming cavities, and pre-drilled holes are connected to the bottom of these grooves. Top plates are provided within the fixed plate grooves, and top rods are welded to the bottom of the top plates, passing through the pre-drilled holes. An electric cylinder B is connected to the top of the base, located between the supporting plates, via a connecting plate. The output shaft of the electric cylinder B is connected via screws.

[0005] The above-mentioned sheet metal stamping equipment for the distribution cabinet achieves automatic demolding and material ejection, avoiding material jamming. It also applies simultaneous force from the four corners of the sheet metal bottom to prevent deformation during demolding. However, after the sheet metal parts are stamped and ejected from the lower die, manual removal of the ejected parts is still required, followed by manual placement of the next sheet metal piece onto the lower die for the next stamping operation. This results in a high workload and low levels of safety and automation.

[0006] Therefore, a solution needs to be proposed to address this problem. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the present invention aims to provide a stamping device for producing distribution cabinets. By setting up an automatic loading and unloading structure, manual loading and unloading is eliminated during the stamping process, making loading and unloading safer and reducing manual workload.

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a stamping device for producing distribution cabinets, comprising two supporting vertical plates and a processing table fixed above the supporting vertical plates. A lower die base is provided on the upper surface of the processing table, and an upper die base for stamping is provided on the upper surface of the processing table. A telescopic rod is fixedly installed on one side of the processing table, and a push plate is fixedly connected to the output end of the telescopic rod. A feeding port is opened on the upper surface of the processing table, located between the telescopic rod and the lower die base. Two support plates are fixed below the processing table, and a receiving plate for placing sheet metal is slidably connected between the two support plates. The plate and the feeding port are positioned correspondingly. Both sides of the support plate are equipped with lifting devices for raising and lowering the receiving plate. A fixed plate is fixedly installed on the upper surface of the processing table. A movable plate is slidably connected to the side wall of the fixed plate. A sliding device for moving the movable plate is installed on the fixed plate. A horizontal plate is fixedly installed on the side wall of the movable plate. An electric cylinder is fixedly installed on the upper surface of the horizontal plate. The output end of the electric cylinder passes through the horizontal plate and is fixedly connected to a driving plate. A mounting frame is fixedly installed on the lower surface of the driving plate. Several suction cups are fixedly connected to the lower surface of the mounting frame. The suction cups are connected to an external negative pressure system through flexible hoses.

[0009] By adopting the above technical solution, during the feeding operation, the sheet metal to be stamped is first stacked on the receiving plate. Then, the lifting device drives the receiving plate to rise, allowing the top sheet metal to pass through the feeding port and reach the upper surface of the processing table. At this time, the height of the top sheet metal corresponds to the height of the push plate, and the bottom wall of the top sheet metal is higher than the upper surface of the upper die base. Next, the telescopic rod is activated and drives the push plate to move, pushing the top sheet metal at the feeding port into the lower die base, completing the feeding process. After the upper die base has finished stamping the sheet metal, the sliding device drives the moving plate to move, causing the suction cup under the mounting frame to move above the lower die base. The electric cylinder is activated and drives the moving plate to descend, and the suction cup contacts the stamped sheet metal. The external negative pressure system generates negative pressure on the suction cup through the hose, thereby adsorbing and fixing the sheet metal. Afterward, the electric cylinder drives the sheet metal to rise, and the suction cup will lift the stamped sheet metal off the lower die base. The sliding device again drives the moving plate to move in the opposite direction, transporting the sheet metal to the designated unloading area. The negative pressure system stops working, and the sheet metal is detached from the suction cup, completing the unloading operation. The entire loading and unloading process requires no direct human intervention, effectively avoiding potential safety accidents that may occur when manually handling the sheet metal. It also greatly reduces the workload of operators and improves the automation level and production efficiency of stamping.

[0010] The invention is further configured such that: the lifting device includes a receiving groove formed on the side wall of the support plate and a lead screw 1 rotatably connected to the inner wall of the receiving groove; a driving mechanism is provided between the two support plates; the driving mechanism is used to drive the lead screw 1 on both sides to rotate synchronously; a nut seat 1 is sleeved on each of the lead screw 1 on both sides; and the nut seats 1 on both sides are fixedly connected to the side wall of the receiving plate.

[0011] By adopting the above technical solution, when the receiving plate needs to be raised or lowered, the drive mechanism will drive the lead screws on both sides to rotate synchronously. Since the nut seat is threadedly connected to the lead screw and fixedly connected to the receiving plate, and the receiving plate is slidably connected between the two support plates, the nut seat cannot rotate with the lead screw; it can only move along the axial direction of the lead screw. Therefore, the nut seats on both sides will drive the receiving plate to rise or fall stably between the support plates, thereby adjusting the height of the plate on the receiving plate and ensuring that the plate at the top of the receiving plate can be accurately pushed to the lower die for stamping through the loading port. This lifting method achieved through the lead screw and nut structure features high transmission accuracy and smooth operation, precisely controlling the lifting height of the receiving plate and ensuring the smoothness and accuracy of the loading process.

[0012] The present invention is further configured such that: the driving mechanism includes two sets of mounting grooves respectively disposed on the two side support plates; one end of each of the two side lead screws extends into the mounting groove and is fixedly connected to a bevel gear; a rotating rod is rotatably connected between the inner walls of the two side mounting grooves; two bevel gears are fixedly sleeved on the outer wall of the rotating rod; the two bevel gears on both sides mesh with the two side bevel gears respectively; and a motor for driving the rotating rod to rotate is fixedly installed on the outer wall of one side support plate.

[0013] By adopting the above technical solution, when the motor starts, its output shaft drives the rotating rod to rotate. During the rotation of the rotating rod, the two bevel gears fixedly sleeved on its outer wall also rotate synchronously. Since the bevel gears on both sides mesh with the bevel gears on both sides that extend into the mounting slots, the rotation of the bevel gears drives the bevel gears to rotate, which in turn drives the lead screws fixedly connected to the bevel gears to rotate. In this way, by driving only one motor, the synchronous rotation of the lead screws on both sides can be achieved through the cooperation of the rotating rod, bevel gears, and bevel gears. This driving method is not only compact in structure and can realize the transmission and distribution of power in a limited space, but also ensures the synchronicity and stability of the rotation of the lead screws on both sides through gear meshing transmission, avoiding the problem of tilting or jamming when the receiving plate is raised or lowered due to asynchronous rotation speeds of the lead screws on both sides, further improving the reliability of the lifting device.

[0014] The present invention is further configured such that: the sliding device includes a groove formed on the side wall of the fixed plate and a second lead screw rotatably connected to the inner wall of the groove; a second motor for driving the second lead screw to rotate is fixedly installed on the side wall of the fixed plate; a second nut seat is sleeved on the second lead screw; and the second nut seat is fixedly connected to the side wall of the moving plate.

[0015] By adopting the above technical solution, when motor two starts, its output shaft drives screw two to rotate within the groove. Since nut seat two is threadedly connected to screw two and fixedly connected to the moving plate, the movement of nut seat two causes the connected moving plate to slide on the fixed plate. This, in turn, through components such as the horizontal plate and electric cylinder, drives the suction cup to achieve horizontal position adjustment. After the sheet metal is stamped, the sliding device can precisely move the suction cup above the lower die seat for material removal. After removal, the sheet metal can be smoothly transported to the unloading area. The entire process is characterized by smooth transmission and precise positioning, effectively ensuring the automation and accuracy of the unloading operation and avoiding the positional deviations and inefficiencies that may result from manual handling.

[0016] The invention is further configured such that: a base plate is fixedly connected between the two support plates; a sliding groove is provided at each of the four edges of the base plate; a slider is slidably connected to the inner wall of each sliding groove; an L-shaped folding plate is fixedly connected to the side wall of each slider; an mounting plate is provided on both sides of each slider; the mounting plate is fixedly connected to the upper end face of the base plate; a fastening hole is provided on the side wall of the folding plate; a through groove corresponding to the position of the fastening hole is provided on the mounting plate; fastening bolts are inserted into the fastening hole and the through groove; a limit rod is fixedly connected to the upper end face of the slider; the side wall of the limit rod is in contact with the side wall of the plate; and a limit groove is provided on the receiving plate for the limit rod to pass through.

[0017] By adopting the above technical solution, before placing the sheet material, the sliding block can be adjusted according to the size of the sheet material to change the position of the limiting rod. This ensures that the side wall of the limiting rod fits tightly against the side wall of the sheet material, effectively limiting the stacked sheet material on the receiving plate and preventing the sheet material from shifting or tipping over during the lifting and lowering of the receiving plate. Once the limiting rod is properly adjusted, the fastening bolts are passed through the fastening holes on the folding plate and the through groove on the mounting plate, and tightened to fix the sliding block in the groove, thus fixing the position of the limiting rod. This adjustable limiting structure allows the receiving plate to adapt to the placement requirements of sheet materials of different sizes, improving the versatility and practicality of the device, ensuring the stability of the sheet material during conveying, and guaranteeing the accuracy of feeding.

[0018] The present invention is further configured such that: a fixing rod is fixedly connected to the inner wall of the receiving groove, and a through hole is provided on the nut seat for the fixing rod to pass through.

[0019] By adopting the above technical solution, when the lead screw drives the nut seat to move up and down, the fixed rod can pass through the through hole and guide and limit the movement of the nut seat. This ensures that the nut seat will not rotate due to the rotation of the lead screw as it moves along the axial direction of the lead screw, thus guaranteeing the stability and straightness of the movement of the nut seat.

[0020] The present invention is further configured such that: a fixing rod 2 is fixedly connected to the inner wall of the groove, and a through hole 2 is provided on the nut seat 2 for the fixing rod 2 to pass through.

[0021] By adopting the above technical solution, when the lead screw 2 drives the nut seat 2 to move horizontally, the fixing rod 2 passes through the through hole 2, which can accurately guide the movement direction of the nut seat 2. This effectively prevents the nut seat 2 from deflecting or shaking due to the rotation of the lead screw 2 during movement, ensuring that the nut seat 2 can move smoothly and steadily along the axial direction of the lead screw 2. This, in turn, ensures the positional accuracy of the moving plate driving the suction cup to pick up and unload materials, avoiding the situation where the material is deflected or falls off due to unstable movement, and further improving the reliability and stability of the entire unloading process.

[0022] In summary, the present invention has the following beneficial effects: This invention automates the loading and unloading process of electrical control cabinet sheet metal during stamping by implementing an automatic loading and unloading structure. In practical application, a lifting device raises the receiving plate of the stacked sheet metal, bringing the top sheet metal to the upper surface of the processing table. A telescopic rod then drives a pusher plate to push the sheet metal to the lower die base, completing the loading. After stamping, a sliding device moves a moving plate, which, in conjunction with an electric cylinder, drives a suction cup to descend and absorb the sheet metal, which is then transported to the designated unloading area for unloading. The entire process requires no direct human intervention, avoiding the safety hazards of manual operation, significantly reducing manual workload, and effectively improving the automation level and production efficiency of stamping processing.

[0032] The lifting device includes a receiving groove 17 opened on the side wall of the support plate 8 and a lead screw 18 rotatably connected to the inner wall of the receiving groove 17.

[0036] A fixing rod 39 is fixedly connected to the inner wall of the groove 25, and a through hole 2 is provided on the nut seat 27 for the fixing rod 39 to pass through.

[0037] A base plate 29 is fixedly connected between the two side support plates 8. Slide grooves 30 are provided around the four edges of the base plate 29. Sliding sliders 31 are slidably connected to the inner walls of the slide grooves 30. L-shaped folding plates 32 are fixedly connected to the side walls of each slider 31. Mounting plates 33 are provided on both sides of each slider 31, and are fixedly connected to the upper surface of the base plate 29. Fastening holes are provided on the side walls of the folding plates 32. Through grooves 34 corresponding to the fastening holes are provided on the mounting plates 33. Fastening bolts 35 pass through the fastening holes and through grooves 34. A limiting rod 36 is fixedly connected to the upper surface of the slider 31. The side wall of the limiting rod 36 fits against the side wall of the material. A limiting groove 37 is provided on the receiving plate 9 for the limiting rod 36 to pass through. The height of the limiting rod 36 is lower than the height of the feeding port 7 to prevent the limiting rod 36 from colliding with the push plate 6 when pushing the material.

[0038] Working principle: When using this stamping device, firstly, adjust the position of the upper limit rod 36 on the base plate 29 according to the size of the distribution cabinet plate to be processed. Specifically, loosen the fastening bolts 35 to allow the slider 31 to slide within the groove 30, moving the limit rod 36 until the side wall of the limit rod 36 fits tightly against the side wall of the plate. Then, retighten the fastening bolts 35 to fix the slider 31, thus completing the limit adaptation for plates of different sizes. Next, place the neatly stacked plates on the receiving plate 9; the plates remain stable under the action of the limit rod 36.

[0039] After the device is started, motor 24 drives rotating rod 22 to rotate. Through the meshing transmission of bevel gear 23 and bevel gear 21, it drives the lead screws 18 on both sides to rotate synchronously. Under the action of the thread of lead screw 18, nut seat 19 drives the receiving plate 9 to rise smoothly along the guide direction of fixed rod 38, so that the uppermost plate passes through the loading port 7 and rises to a position flush with the upper end surface of processing table 2. Then, motor 24 is turned off, and receiving plate 9 stops at the current height. At this time, telescopic rod 5 is activated, and its output end pushes push plate 6 to push the plate into lower die base 3. Subsequently, electric cylinder 13 drives the mounting table to lower upper die base 4, which closes with lower die base 3 to complete the stamping process of the plate in lower die base 3.

[0040] After stamping, the upper die base 4 rises, motor 28 starts, driving lead screw 26 to rotate. Nut seat 27 moves along fixed rod 39, guiding the moving plate 11 to move, causing suction cup 16 to move above the lower die base 3. Next, electric cylinder 13 drives plate 14 and mounting bracket 15 to descend, bringing suction cup 16 into contact with the upper surface of the processed sheet metal. The external negative pressure system, through a hose, generates suction force on suction cup 16, holding the sheet metal in place. Multiple suction cups 16 are spaced apart, ensuring more even force distribution on the sheet metal during suction. Afterward, electric cylinder 13 drives suction cup 16 to rise, and motor 28 again drives moving plate 11, conveying the sheet metal horizontally to the designated unloading area, staggered from the upper die base 4 and lower die base 3. The negative pressure system stops working, and the sheet metal detaches from suction cup 16, completing the unloading process. During this process, fixed rod 38 and fixed rod 39 provide stable guidance for the movement of nut seat 19 and nut seat 27, respectively, ensuring smooth lifting of the receiving plate 9 and precise movement of suction cup 16.

[0041] Then, the motor 24 drives the lead screw 18 to rotate again, causing the receiving plate 9 to rise again. This brings the next piece of material stacked on the receiving plate 9 to the height corresponding to the push plate 6. The push plate 6 can then push the next piece of material onto the lower die base 3 for reprocessing through the extension and retraction of the telescopic rod 5. This cycle is repeated to continuously feed the stacked materials on the receiving plate 9. After the entire stack of materials is fed, the motor 24 drives the rotating rod 22 to rotate in the opposite direction. This drives the lead screw 18 on both sides to rotate in the opposite direction through the bevel gear 21 and bevel gear 23, causing the nut seat 19 to lower the receiving plate 9 back to its original position. The operator then places new raw materials on the receiving plate 9. The entire loading and unloading process is more automated, reducing manual intervention steps and effectively improving the efficiency and safety of the stamping process of the power distribution cabinet materials.

[0042] The above method can be coordinated and controlled by a controller and a preset program. All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer, which is a mature existing technology and will not be elaborated here.
