Description

Technical Field

[0001] This utility model relates to the field of metal stamping technology, and in particular to a forming stamping device for ferrous metal casting. Background Technology

[0002] Forming and stamping equipment for ferrous metal casting is a key piece of equipment in the ferrous metal processing field. It is mainly used to form parts or blanks with specific shapes and sizes from liquid or solid ferrous metals (such as iron and steel) through a stamping process. The following are its main uses and characteristics. However, existing equipment cannot quickly center and fix sheet metal when processing it, which leads to deviations in pressure bearing and waste of raw materials.

[0003] However, existing technologies, such as Chinese Publication No. CN221537876U, "A Forming Stamping Device for Ferrous Metal Casting," disclose a forming stamping device for ferrous metal casting, including a stamping table with a stamping die for ferrous metal casting at its top. The stamping die has multiple auxiliary mechanisms for connection and fixation, including a support rod, a mounting ring, and a reinforcing rod. The stamping die is connected to the stamping table via the support rod, and the mounting ring is engaged with the support rod via the reinforcing rod. It also includes a sliding frame and a limiting plate. This invention utilizes the cooperation of the stamping die, support rod, sliding frame, limiting plate, mounting ring, and reinforcing rod. The stamping die is connected to the support rod, and the sliding frame drives the limiting plate and reinforcing rod to move. The limiting plate limits the relative position of the stamping die and the support rod, and the reinforcing rod limits the relative position of the mounting ring and the support rod. This facilitates the installation and disassembly of the stamping die, making it easy to remove, maintain, or replace, and simplifying operation.

[0004] However, this device lacks a central clamping and fixing structure, which cannot ensure that the metal billet or sheet metal is at the geometric center in the mold. This leads to asymmetrical shape and out-of-tolerance dimensions of the stamped parts due to offset. It cannot provide a unified positioning reference for subsequent stamping processes, increases cumulative errors, is not suitable for multi-station continuous stamping scenarios, cannot adapt to automatic feeding structures, increases manual labor costs, and cannot ensure the forming quality, production efficiency, and equipment safety of ferrous metal parts. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as the inability to ensure that the metal billet or sheet is at the geometric center of the mold, resulting in asymmetrical shape and out-of-tolerance dimensions of the stamped parts due to offset, the inability to provide a unified positioning reference for subsequent stamping processes, the increase of cumulative errors, unsuitability for multi-station continuous stamping scenarios, inability to adapt to automatic feeding structures, increased labor costs, and inability to ensure the forming quality, production efficiency, and equipment safety of ferrous metal parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a forming stamping device for ferrous metal casting, comprising a pressure-bearing base shell, stamping devices fixedly connected to both sides of the pressure-bearing base shell, a pressure plate fixedly connected to the top of the pressure-bearing base shell, a rotating rod rotatably connected to the top of the pressure-bearing base shell, a synchronization component provided at the top of the rotating rod, the synchronization component including a gear, the bottom of the gear fixedly connected to the top of the rotating rod, two racks meshing with the outer surface of the gear, a central clamping plate fixedly connected to one end of the racks, two connecting rods fixedly connected to the bottom of the central clamping plate, a limiting sleeve fixedly connected to the bottom of the connecting rods, a limiting rod movably embedded in the inner surface of the two limiting sleeves, and both ends of the two limiting rods fixedly connected to the inner surface of the pressure-bearing base shell. The gear rotating with the rotating rod will, under the meshing action of the racks, drive the two central clamping plates, connecting rods and limiting sleeves to move closer to each other along the axial direction of the limiting rods.

[0007] In a preferred embodiment, the synchronization component further includes a synchronization rod, the bottom of which is fixedly connected to the top of the rotating rod. Both ends of the synchronization rod are rotatably connected to connecting rods, allowing the rotating rod to drive the synchronization rod to rotate, which in turn drives the connecting rods at both ends.

[0008] In a preferred embodiment, the end of the connecting rod away from the synchronizing rod is rotatably connected to a shaft block, and the side of the shaft block away from the connecting rod is fixedly connected to the outer surface of the central clamping plate. The other end of the connecting rod will pull the central clamping plate through the shaft block.

[0009] In a preferred embodiment, a worm gear is fixedly connected to the bottom of the rotating rod, and a worm is meshed with the outer surface of the worm gear. Under the meshing action of the worm and the worm gear, the rotating rod will be driven to rotate on the top of the pressure-bearing bottom shell.

[0010] In a preferred embodiment, the outer surface of the worm gear is rotatably connected to two shaft plates and extends out at one end. The top of the two shaft plates is fixedly connected to the inner surface of the pressure-bearing base shell. A first motor is fixedly connected to the top of the inner surface of the pressure-bearing base shell. The output end of the first motor is fixedly connected to the extended end of the worm gear. When the first motor is energized, it will drive the worm gear to rotate inside the shaft plates.

[0011] In a preferred embodiment, an external plate is fixedly connected to the top of the pressure-bearing bottom shell, and a fixing plate is fixedly connected to one side of the pressure-bearing bottom shell. The end of the fixing plate away from the pressure-bearing bottom shell is fixedly connected to the bottom of the external plate, and the external plate is fixed to one side of the pressure-bearing bottom shell by the fixing plate.

[0012] In a preferred embodiment, a fixed plate is rotatably connected to the interior of the outer plate, and a threaded rod is rotatably connected to the interior of the fixed plate, extending to one end. An internal threaded sleeve is threadedly connected to the outer surface of the threaded rod, and a push block is fixedly connected to the top of the internal threaded sleeve. The outer surface of the push block is movably embedded in the inner surface of the outer plate. Rotating the thread will drive the internal threaded sleeve, causing the push block to move forward inside the outer plate and initially push the plate above the pressure plate.

[0013] In a preferred embodiment, a mounting sleeve is fixedly connected to one side of the outer plate, and a second motor is fixedly embedded on the inner surface of the mounting sleeve. The output end of the second motor is fixedly connected to one end of the threaded rod. When the second motor is energized, it will drive the threaded rod to rotate inside the outer plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

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.

[0024] Example 1, please refer to Figures 1 to 5This utility model provides a technical solution: a forming stamping device for ferrous metal casting, including a pressure-bearing base shell 1, stamping devices 2 fixedly connected to both sides of the pressure-bearing base shell 1, a pressure plate 3 fixedly connected to the top of the pressure-bearing base shell 1, a rotating rod 4 rotatably connected to the top of the pressure-bearing base shell 1, a synchronization component provided at the top of the rotating rod 4, the synchronization component including a gear 5, the bottom of the gear 5 fixedly connected to the top of the rotating rod 4, two racks 6 meshing with the outer surface of the gear 5, a central clamping plate 7 fixedly connected to one end of the racks 6, two connecting rods 8 fixedly connected to the bottom of the central clamping plate 7, a limiting sleeve 9 fixedly connected to the bottom of the connecting rod 8, a limiting rod 10 movably embedded in the inner surface of the two limiting sleeves 9, both ends of the two limiting rods 10 fixedly connected to the inner surface of the pressure-bearing base shell 1, a worm gear 14 fixedly connected to the bottom of the rotating rod 4, a worm 15 meshing with the outer surface of the worm gear 14, two shaft plates 16 rotatably connected to the outer surface of the worm 15 and extending out one end, and so on. The tops of the two shaft plates 16 are fixedly connected to the inner surface of the pressure-bearing base shell 1. The top of the inner surface of the pressure-bearing base shell 1 is fixedly connected to the first motor 17. The output end of the first motor 17 is fixedly connected to one end of the worm gear 15. The top of the pressure-bearing base shell 1 is fixedly connected to the outer plate 18. The side of the pressure-bearing base shell 1 is fixedly connected to the fixing plate 19. The end of the fixing plate 19 away from the pressure-bearing base shell 1 is fixedly connected to the bottom of the outer plate 18. The fixing plate 19 is rotatably connected inside the outer plate 18. The threaded rod 20 is rotatably connected inside the fixing plate 19 and extends out one end. The outer surface of the threaded rod 20 is threadedly connected to the inner threaded sleeve 21. The top of the inner threaded sleeve 21 is fixedly connected to the push block 22. The outer surface of the push block 22 is movably embedded in the inner surface of the outer plate 18. The side of the outer plate 18 is fixedly connected to the mounting sleeve 23. The inner surface of the mounting sleeve 23 is fixedly embedded with the second motor 24. The output end of the second motor 24 is fixedly connected to one end of the threaded rod 20.

[0025] In this embodiment, the black metal sheet to be stamped is first placed above the push block 22 of the outer plate 18. Then, the external power supply of the second motor 24 is turned on. The second motor 24 is fixed to one side of the outer plate 18 by the mounting sleeve 23. After the second motor 24 is powered on, it will drive the threaded rod 20 to rotate inside the outer plate 18. The outer plate 18 is fixed to one side of the pressure-bearing bottom shell 1 by the fixing plate 19. The rotation of the thread will drive the inner threaded sleeve 21, so that the push block 22 is pushed forward inside the outer plate 18 and the sheet is initially pushed above the pressure plate 3. Then, the external power supply of the first motor 17 is turned on. When the first motor 17 is powered on, it drives the worm gear 15 to rotate inside the shaft plate 16. Under the meshing action of the worm gear 15 and the worm wheel 14, it drives the rotating rod 4 to rotate on the top of the pressure-bearing bottom shell 1. The gear 5, which rotates with the rotating rod 4, will drive the two central clamping plates 7, the connecting rod 8 and the limiting sleeve 9 to move closer to each other along the axis of the limiting rod 10 under the meshing action of the rack 6, and centrally clamp and fix the metal plate above the pressure plate 3. Then the stamping machine 2 can perform work. The stamping machine 2, as an existing device, can stamp the metal plate on the pressure plate 3.

[0026] Example 2, please refer to Figures 1 to 5 The synchronization assembly also includes a synchronization rod 11. The bottom of the synchronization rod 11 is fixedly connected to the top of the rotating rod 4. Both ends of the synchronization rod 11 are rotatably connected to connecting rods 12. The end of the connecting rod 12 away from the synchronization rod 11 is rotatably connected to a shaft block 13. The side of the shaft block 13 away from the connecting rod 12 is fixedly connected to the outer surface of the central clamping plate 7.

[0027] In this embodiment, fixing the metal can also cause the rotating rod 4 to drive the synchronous rod 11 to rotate. The synchronous rod 11 will drive the connecting rods 12 at both ends. The other end of the connecting rod 12 will pull the central clamping plate 7 through the shaft block 13, so that the two central clamping plates 7, the connecting rod 8 and the limiting sleeve 9 move closer to each other along the axis of the limiting rod 10, and centrally clamp and fix the metal plate above the pressure plate 3.

[0028] Working principle: First, the black metal sheet to be stamped is placed above the push block 22 of the outer plate 18. Then, the external power supply of the second motor 24 is turned on. The second motor 24 is fixed to one side of the outer plate 18 by the mounting sleeve 23. After the second motor 24 is powered on, it will drive the threaded rod 20 to rotate inside the outer plate 18. The outer plate 18 is fixed to one side of the pressure base shell 1 by the fixing plate 19. The rotation of the thread will drive the inner threaded sleeve 21, so that the push block 22 is pushed forward inside the outer plate 18, and the sheet is initially pushed above the pressure plate 3. Then, the external power supply of the first motor 17 is turned on. After the first motor 17 is powered on, it will drive the worm gear 15 to rotate inside the shaft plate 16. Under the meshing action of the worm gear 15 and the worm wheel 14, it will drive the rotating rod 4 to rotate on the top of the pressure base shell 1. As the rotating rod 4 rotates, the gear 5, which meshes with the rack 6, drives the two central clamping plates 7, the connecting rod 8, and the limiting sleeve 9 to move closer together along the axis of the limiting rod 10, thus centrally clamping and fixing the metal plate above the pressure plate 3. Then, the stamping machine 2 can perform its work. As an existing device, the stamping machine 2 can stamp the metal plate on the pressure plate 3 and fix the metal. The rotating rod 4 can also drive the synchronous rod 11 to rotate. The synchronous rod 11 will drive the connecting rods 12 at both ends. The other end of the connecting rod 12 will pull the central clamping plate 7 through the shaft block 13, so that the two central clamping plates 7, the connecting rod 8, and the limiting sleeve 9 move closer together along the axis of the limiting rod 10, thus centrally clamping and fixing the metal plate above the pressure plate 3.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
