Description

Technical Field

[0001] This utility model relates to the field of stamping machine technology, specifically a stamping machine for metal forming and processing. Background Technology

[0002] In the production of medical furniture, metal sheets need to be processed. During the production process, the metal forming stamping machine usually forms a mold cavity by the cooperation of the moving mold assembly and the stationary mold assembly to form the workpiece.

[0003] Patent CN222754173U discloses a metal parts stamping forming fixture, including a stamping machine, a worktable, and a demolding assembly. The demolding assembly includes a gantry frame, a limiting mechanism, a first cylinder, an upper die, a lower die, a mounting plate, and a second cylinder. The stamping machine is used to deform the sheet metal under pressure during parts processing. The worktable is used to operate parts processing. The stamping machine is mounted via the gantry frame, and the upper die is fixed to the stamping machine via the mounting plate. During stamping, the sheet metal is placed on the lower die, and then the stamping machine controls the upper die to stamp the lower die. After processing, the first cylinder controls the output end to eject the part from one side of the upper die, and the second cylinder controls the output end to eject the part from the lower die, thereby forming a rapid demolding. The limiting mechanism restricts the position of the sheet metal in the lower die.

[0004] As shown in the above technology, the mold structure of existing stamping machines is often fixedly installed on the stamping machine body. When the mold is worn, damaged, or needs to be replaced with a mold of a different shape, it is necessary to disassemble the entire moving mold or stationary mold assembly. During the mold replacement process, due to the complexity of the disassembly and assembly steps, there is a risk of inaccurate positioning or insecure installation. This process not only takes a long time, but also increases the downtime of the equipment, which seriously affects production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stamping machine for metal forming and processing. It solves the problem that when a mold is worn, damaged, or needs to be replaced with a mold of a different shape, it is necessary to disassemble the entire moving mold or stationary mold assembly. During the mold replacement process, due to the complexity of the disassembly and assembly steps, there is a risk of inaccurate positioning or insecure installation. This process is not only time-consuming, but also increases the downtime of the equipment, seriously affecting production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping machine for metal forming, comprising: A working base, wherein a working top seat is fixedly connected to one side of the working base, and a stamping rod is movably connected to one side of the working top seat; A moving mold assembly, one side of which is fixedly connected to the bottom end of a stamping rod, is used to complete the forming and demolding of the workpiece and can be quickly replaced. A static mold assembly, the bottom of which is fixedly connected to the surface of the working base, is used to cooperate with the moving mold to form a mold cavity to withstand the forming pressure and can be replaced synchronously.

[0007] Preferably, the moving mold assembly includes a central block fixedly connected to the bottom end of the stamping rod, with transverse guide rails fixedly connected to both sides of the central block, and transverse limiting plates movably connected to the inner walls of the transverse guide rails.

[0011] Preferably, the surface of the support plate is perforated with bottom bolts, and the top of the support plate is fixedly connected to a static module.

[0012] This utility model provides a stamping machine for metal forming. Compared with the prior art, it has the following advantages: 1. This metal forming stamping press incorporates a detachable stamping head moving module and its corresponding mounting plate, dovetail block and vertical dovetail groove, transverse guide rail, and transverse limiting plate in its moving die assembly structure. This allows the moving module to be replaced directly without disassembling the entire moving die assembly. This design significantly shortens die changeover time and avoids the complex positioning and debugging processes associated with disassembling and assembling the entire moving die. During mass production, when the stamping head wears out or needs to be replaced with a different shape, the operator only needs to loosen the screw rod, pull out the moving module, and insert the new stamping head to complete the replacement. The entire process is simple to operate, accurate in positioning, and greatly improves production efficiency. Furthermore, the quick-change structure of this moving die assembly significantly reduces labor costs and equipment downtime losses during maintenance, making it suitable for multi-variety, small-batch, and continuous batch production environments, providing enterprises with greater flexibility in production.

[0013] 2. In this metal forming stamping press, the stationary die assembly of this application features a sliding groove and a mounting groove on the working base. The stationary die head and stationary module are mounted via a moving block and a support plate structure, and employ a detachable design with bottom bolts for fixation. This allows the stationary module to be quickly removed and replaced with a new module along the sliding groove when replacement is needed. Compared to traditional fixed stationary die structures, this design significantly improves the replacement speed and maintenance convenience of the stationary die while ensuring its stability and processing accuracy. In production, when the stationary die head experiences mold cavity wear due to prolonged use or when a different mold shape needs to be replaced due to process changes, the operator does not need to disassemble the entire stationary die assembly. They can simply loosen the bottom bolts and move the support plate along the sliding groove to replace the stationary module, thereby reducing equipment downtime, lowering production costs, and improving the safety and efficiency of mold maintenance.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figures 1-7 This utility model provides two technical solutions: Example 1: A stamping press for metal forming and processing, comprising: The working base 1 has a working top seat 2 fixedly connected to one side, and a stamping rod 3 movably connected to one side of the working top seat 2. The moving mold assembly 4 is fixedly connected to the bottom end of the stamping rod 3 on one side. The moving mold assembly 4 is used to complete the forming and demolding of the workpiece and can be quickly replaced. The stationary mold assembly 5 is fixedly connected to the surface of the working base 1 at its bottom. The stationary mold assembly 5 works in conjunction with the moving mold to form a mold cavity to withstand forming pressure and can be replaced synchronously. The moving mold assembly 4 of this application incorporates a detachable stamping head moving module 45 and its corresponding mounting plate 46, dovetail block 411, vertical dovetail groove 44, horizontal guide rail 42, and horizontal limiting plate 43. This allows the moving module 45 to be replaced directly without disassembling the entire moving mold assembly 4. This design significantly shortens mold changeover time and avoids the complex positioning and debugging processes caused by disassembling and assembling the entire moving mold. During mass production, when the stamping head wears out or needs to be replaced with a different shape, the operator only needs to loosen the screw rod 412, pull out the moving module 45, and insert a new stamping head to complete the replacement. The entire process is simple to operate, accurately positioned, and greatly improves production efficiency. In addition, the quick-change structure of the moving mold assembly 4 can significantly reduce labor costs and equipment downtime losses during maintenance, making it suitable for multi-variety, small-batch and continuous batch production environments, providing enterprises with higher flexible production capabilities.

[0018] Example 2 differs from Example 1 mainly in that: a metal forming stamping machine, the moving die assembly 4 includes a central block 41 fixedly connected to the bottom end of the stamping rod 3, transverse guide rails 42 fixedly connected to both sides of the central block 41, transverse limiting plates 43 movably connected to the inner walls of the transverse guide rails 42, vertical dovetail grooves 44 formed on both sides of the bottom of the central block 41, mounting sleeves 46 movably connected to the surface of the central block 41, a stabilizing block 47 fixedly connected to the top of the mounting sleeves 46, a transverse limiting groove 48 formed on the surface of the stabilizing block 47, the transverse limiting groove 48 and the transverse limiting plate 43 being mutually adapted, a vertical column 49 fixedly connected to the top of the stabilizing block 47, a sealing frame 410 movably fitted onto the surface of the vertical column 49, the length between the inner walls of the two sides of the sealing frame 410 being the same as the length of the transverse limiting plate 43, which can directly seal it in the transverse limiting groove 48, the inner wall of the mounting sleeve 46 being fixedly connected to the horizontal limiting plate 43. A dovetail block 411 is fixedly connected, and the dovetail block 411 is adapted to the vertical dovetail groove 44. A screw rod 412 passes through the inner wall of the mounting sleeve 46. A moving module 45 is fixedly connected to the bottom of the mounting sleeve 46. The stationary mold assembly 5 includes a sliding groove 51 opened on the surface of the working base 1. An installation groove 52 is opened at the bottom of the sliding groove 51. A moving block 53 is movably connected to the surface of the sliding groove 51. A bearing plate 54 is fixedly connected to the bottom of the moving block 53. A bottom bolt 55 passes through the surface of the bearing plate 54. A stationary module 56 is fixedly connected to the top of the bearing plate 54. The stationary mold assembly 5 of this application has a sliding groove 51 and an installation groove 52 on the working base 1. The stationary mold head stationary module 56 is installed through the moving block 53 and the bearing plate 54 structure. The stationary module 56 is fixed with a detachable design with a bottom bolt 55, so that the stationary module 56 can be quickly taken out and replaced with a new module along the direction of the sliding groove 51 when it needs to be replaced. Compared to traditional fixed static mold structures, this design significantly improves the speed of static mold replacement and ease of maintenance while ensuring the stability and machining accuracy of the static mold. During production, when the mold cavity wears down due to prolonged use or when a different mold shape needs to be replaced due to process changes, the operator does not need to disassemble the entire static mold assembly 5. They can simply loosen the bottom bolts 55 and move the support plate 54 along the sliding groove 51 to replace the static mold module 56. This reduces equipment downtime, lowers production costs, and simultaneously improves the safety and efficiency of mold maintenance.

[0019] Guide rods are provided on both sides of the vertical column 49. The bottom of the guide rods will not exceed the top of the transverse limiting groove 48, so as not to affect the normal operation of the transverse limiting plate 43.

[0020] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0021] During operation, turn on the equipment, place the stamping material on top of the stationary die assembly 5, and use the stamping rod 3 to drive the moving die assembly 4 to stamp and form the material. After working for a period of time, when maintaining it or changing the stamping shape according to production needs, rotate the screw rod 412 to separate the screw rod 412 from the central block 41 and the mounting sleeve plate 46. Then pull up the sealing frame 410 on the surface of the stabilizing block 47 and move the sealing frame 410 up along the vertical column 49 to expose the transverse limiting groove 48. Pull the transverse limiting plate 43 out along the transverse guide rail 42 and remove it. Pull down the mounting sleeve plate 46 to make the dovetail block 411 slide down along the vertical dovetail groove 44. Remove the mounting sleeve plate 46 and the moving module 45 from the surface of the central block 41. Repeat the above reverse operation to complete the replacement. Continue rotating the bottom bolt 55 to separate it from the sliding groove 51 and the mounting groove 52, and then from the moving block 53 and the bearing plate 54. Finally, slide the bearing plate 54 and the stationary module 56 in the sliding groove 51, remove them and replace them, and continue working. When the device is completely finished, restore it.
