Description

Technical Field

[0001] This invention relates to the field of stamping, specifically to a metal lampshade stamping apparatus. Background Technology

[0002] Stamping refers to a processing method that uses a press and dies to apply external force to sheet metal, strip, tube, and profile, causing plastic deformation or separation to obtain workpieces (stamped parts) of the required shape and size. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Of the world's steel, 60-70% is sheet metal, most of which is stamped into finished products, including metal lampshades, which are also formed by stamping.

[0003] The prior art patent document CN218963755U provides a metal stamping forming device. After the metal part is stamped, it can be easily removed from the stamping groove, avoiding the metal part from getting stuck in the stamping groove. However, when using the patent CN218963755U, the metal sheet is manually placed on the forming device. Manual operation is risky, cannot accurately place the sheet in position, and is inefficient, resulting in low processing efficiency of the entire forming device. Therefore, there is an urgent need for a metal lampshade stamping forming device. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing metal sheet stamping and forming devices, which involve manual placement of metal sheets on forming devices. This manual operation is risky, cannot accurately position the sheets, and is inefficient, resulting in low overall processing efficiency of the forming device. Furthermore, the metal sheets need to be manually handled by workers before and after processing, which is inconvenient. Additionally, the finished lampshades are easily displaced by external forces during stacking, leading to positional deviations and preventing continuous stacking. The invention provides a metal lampshade stamping and forming device.

The power supply board and the air pump are two in number.

[0008] The stacking structure includes a locking plate, a load-bearing plate fixed to the bottom end of the locking plate, an adjustment groove opened on the inner side of the load-bearing plate, a threaded rod movably arranged on the inner side of the adjustment groove, a positioning rod provided at the end of the threaded rod, a threaded block movably arranged on the inner side of the positioning rod, and a support plate fixed to the top of the threaded block.

[0009] Preferably, a drive seat is provided at the top of the equipment plate, a cylinder is installed on the inner side of the drive seat, an upper mold is provided at the output end of the cylinder, a movable seat is provided below the upper mold, a lower mold is installed on the movable seat, and the movable seat is fixedly installed with the processing table.

[0010] Preferably, the electric push rod is fixedly installed on the processing table through a mounting groove, and the inner side of the processing table is provided with a movable groove that matches the electric conveyor belt and the feeding structure, and the limiting rod is fixed to the inner wall of the movable groove.

[0011] Preferably, the equipment housing is fixedly installed with the support ring, and the first motor is fixedly installed with the equipment housing via a bracket, and the extrusion rod is movably connected to the first motor via a rotating shaft.

[0012] Preferably, the second motor and the equipment plate are fixedly installed through a mounting groove, the nut sleeve and the lead screw are connected by a thread, and a limiting groove matching the lead screw and the nut sleeve is provided on the inner side of the equipment plate.

[0013] Preferably, the air pump and the power supply board are fixedly installed by bolts, the number of the first air extraction pipes is two, and the second air extraction pipe and the movable base are fixedly installed by the power supply board and the air pump.

[0014] Preferably, the top of the processing table is provided with a locking groove that matches the stacking structure, and the number of the adjusting groove, positioning rod and support plate is four.

[0015] Preferably, the threaded rod and the adjusting groove are connected by a thread, and the threaded rod and the positioning rod are rotatably connected by a bearing, and the positioning rod and the adjusting groove are engaged.

[0016] Preferably, the top end of the positioning rod has a threaded groove that matches the threaded block, and the support plate and the positioning rod are fixedly connected by the threaded block.

[0017] Compared with the prior art, the beneficial effects of the present invention are: First, this invention, by setting up a placement plate, limiting rods, a first motor, and a pressing rod, allows the metal sheet to fall onto the placement plate. An electric push rod drives the placement plate and the metal sheet at the output end to move upward. As the metal sheet moves upward, it is pressed by the three limiting rods and gradually returns to its original position. The first motor drives the pressing rod at the output end to rotate downward, pressing the metal sheet. This causes the metal sheet to move inward after being subjected to force, and at the same time, under the restriction of the limiting rods and the pressing rod, the position of the metal sheet is aligned, making it easier to accurately load the metal sheet in the center.

[0018] Secondly, this invention, by setting up a first suction pipe, a second suction pipe, a lead screw, a movable seat, and a power supply board, allows metal plates to be adsorbed and fixed on the first and second suction pipes respectively. A second motor drives the lead screw at the output end to rotate, and the lead screw, through the thread and nut sleeve, drives the movable seat and the power supply board to move to the left, so that the first suction pipe moves to the top of the lower die. At this time, the suction pump stops running, and the metal plate on the first suction pipe falls onto the lower die, realizing material feeding. After the stamping is completed, the first suction pipe moves back to the top of the lower die and magnetically adsorbs and fixes the lampshade again. Then the first suction pipe moves to the top of the stacking structure, and the second suction pipe moves to the top of the lower die, so that the lampshade falls onto the stacking structure, and another metal plate falls onto the lower die for a new stamping process. This allows the first and second suction pipes to transport the plates and the formed lampshade simultaneously, improving the processing efficiency of the device.

[0019] Third, this invention, by setting positioning rods, threaded rods, support plates, and adjustment grooves, pre-adjusts the positions of the four positioning rods and the support plate according to the inner wall dimensions of the molded lampshade. First, by screwing the threaded rods, the threaded rods rotate on the load-bearing plate, driving the positioning rods to move in the adjustment grooves through the bearings, thereby adjusting the position. After adjustment, the screwing of the threaded rods is stopped. Then, the support plate is pushed to rotate on the positioning rods through the threaded block at the bottom, adjusting the direction of the support plate. When the lampshade size is small, it is directly clamped and supported by the four positioning rods. When the lampshade size is large, the support plate is pushed to rotate outwards, clamped and supported by the support plate. This allows the lampshade to be locked onto the stacking structure after it falls, preventing the lampshade from moving and facilitating continuous stacking of lampshades.

As the metal sheet gradually returns to its original position and moves to the middle position of the limiting rod 503, the first motor 506 is controlled to run. The internal technology of the first motor 506 is existing technology. After the first motor 506 runs, it drives the extrusion rod 507 at the output end to rotate, causing the extrusion rod 507 to rotate downward and extrude the metal sheet. After being subjected to force, the metal sheet moves inward. At the same time, under the restriction of the limiting rod 503 and the extrusion rod 507, the position of the metal sheet is straightened. Then, the metal sheet in the center position moves upward to the bottom of the first exhaust pipe 607 under the push of the placement plate 502, which facilitates accurate material feeding.

[0024] Please see Figures 7-9A metal lampshade stamping and forming device, wherein the feeding structure 6 includes a second motor 601, a lead screw 602 is provided at the output end of the second motor 601, a nut sleeve 603 is movably provided on the outer side of the lead screw 602, a movable seat 604 is provided at the front end of the nut sleeve 603, a power supply board 605 is provided at the bottom end of the movable seat 604, an air pump 606 is installed on the inner side of the power supply board 605, a first air extraction pipe 607 is connected to the bottom end of the air pump 606, and a second air extraction pipe 607 is provided on one side of the first air extraction pipe 607. 08.

[0025] Please see Figures 10-12A metal lampshade stamping and forming device, wherein the stacking structure 11 includes a locking plate 1101, a load-bearing plate 1102 fixed to the bottom end of the locking plate 1101, an adjustment groove 1103 opened on the inner side of the load-bearing plate 1102, a threaded rod 1104 movably arranged on the inner side of the adjustment groove 1103, a positioning rod 1105 provided at the end of the threaded rod 1104, a threaded block 1106 movably arranged on the inner side of the positioning rod 1105, and a support fixed at the top end of the threaded block 1106. The plate 1107 and the processing table 1 have a locking groove at the top that matches the stacking structure 11. There are four adjustment grooves 1103, positioning rods 1105, and support plates 1107. The threaded rod 1104 is connected to the adjustment groove 1103 by a thread, and the threaded rod 1104 is rotatably connected to the positioning rod 1105 by a bearing. The positioning rod 1105 is movably locked into the adjustment groove 1103. The top of the positioning rod 1105 has a corresponding threaded block 1106. The lampshade is fitted with a threaded groove, and the support plate 1107 and the positioning rod 1105 are fixedly connected by a threaded block 1106. The positions of the four positioning rods 1105 and the support plate 1107 are adjusted in advance according to the inner wall size of the molded lampshade. First, by screwing the threaded rod 1104, the threaded rod 1104 rotates on the load-bearing plate 1102, and the positioning rod 1105 moves in the adjustment groove 1103 through the bearing to adjust the position. After the adjustment is completed, the screwing of the threaded rod 1104 is stopped. Then, the support plate 1107 is pushed to rotate on the positioning rod 1105 through the threaded block 1106 at the bottom end to adjust the direction of the support plate 1107. When the size of the lampshade is small, it can be directly clamped and supported by the four positioning rods 1105. When the size of the lampshade is large, the support plate 1107 is pushed to rotate outward and clamped and supported by the support plate 1107. This allows the lampshade to be locked onto the stacking structure 11 after it falls, preventing the lampshade from moving and facilitating continuous stacking of the lampshade.

[0026] Working Principle: In use, multiple metal sheets are sequentially placed on the electric conveyor belt 4 and transported to the end, then fall naturally onto the placement plate 502. At this time, the electric push rod 501 is activated. The internal technology of the electric push rod 501 is existing technology. After the electric push rod 501 is activated, it drives the placement plate 502 and the metal sheets at the output end to move upwards. As the metal sheets move upwards, they are squeezed by three limit rods 503, gradually returning to their original position. When the metal sheets move to the middle position of the limit rods 503, the first motor 506 is activated. The internal technology of the first motor 506 is existing technology. After the first motor 506 is activated, it drives the extrusion rod 507 at the output end to rotate, causing the extrusion rod 507 to rotate downwards and squeeze the metal sheets, causing the metal sheets to... After being subjected to force, it moves inward, and simultaneously, under the restriction of the limiting rod 503 and the pressing rod 507, the position of the metal plate is aligned. Then, the metal plate in the center is pushed upward by the placement plate 502 to the bottom of the first suction pipe 607 for precise feeding. Then, the suction pump 606 inside the power supply board 605 is controlled to run, and air is drawn through the first suction pipe 607. The strong suction causes the metal plate to move upward and be attracted. At this time, the feeding structure 6 delivers the new metal plate to the top of the support ring 504. Then, the second motor 601 is controlled to run. The internal technology of the second motor 601 is existing technology. After the second motor 601 runs, it drives the lead screw 602 at the output end to rotate. The lead screw 602 then drives the moving seat 604 through the thread and nut sleeve 603. The power supply board 605 moves to the left, causing the second suction pipe 608 to move above the metal plate. Then, the suction pump 606 controls the second suction pipe 608 to draw air. The strong suction causes the metal plate to move upward and be attracted. At this time, the second motor 601 drives the power supply board 605 and the first suction pipe 607 to move above the lower mold 10 through the lead screw 602, nut sleeve 603, and moving seat 604. At this time, the suction pump 606 stops running, and the metal plate on the first suction pipe 607 falls onto the lower mold 10, realizing feeding. The first suction pipe 607 and the second suction pipe 608 move to both sides of the lower mold 10, and the cylinder 7 runs. The internal technology of the cylinder 7 is existing technology. After the cylinder 7 runs, it drives the upper mold 8 at the output end to move downward, and the movable seat 9 moves downward. The lower mold 10 is closed for stamping, forming the metal sheet into a lampshade. After stamping, the first suction pipe 607 moves back above the lower mold 10 and magnetically attaches the lampshade. Then, the first suction pipe 607 moves above the stacking structure 11, and the second suction pipe 608 moves above the lower mold 10, causing the lampshade to fall onto the stacking structure 11. Another metal sheet falls onto the lower mold 10 for a new stamping process. This allows the first suction pipe 607 and the second suction pipe 608 to simultaneously transport the sheet metal and the formed lampshade, improving the processing efficiency of the device. The positions of the four positioning rods 1105 and the support plate 1107 are adjusted beforehand according to the inner wall dimensions of the formed lampshade. First, the threaded rod 1104 is screwed in.The threaded rod 1104 rotates on the load-bearing plate 1102, driving the positioning rod 1105 to move in the adjusting groove 1103 via the bearing to adjust the position. After adjustment, stop turning the threaded rod 1104. Then, insert the load-bearing plate 1102 into the corresponding engaging groove on the processing table 1, with the engaging plate 1101 flush with the surface of the processing table 1. At this time, push the support plate 1107 to rotate on the positioning rod 1105 via the threaded block 1106 at the bottom, adjusting the direction of the support plate 1107. When the lampshade size is small, it can be directly clamped and supported by the four positioning rods 1105. When the lampshade size is large, push the support plate 1107 to rotate outward, clamping and supporting it through the support plate 1107. This allows the lampshade to engage on the stacking structure 11 after falling, preventing the lampshade from moving and facilitating continuous stacking of lampshades.
