A high-precision metal stamping die processing device with a stable structure can be designed. By adopting a stable structure to press and stabilize the sheet, the shift or warping of the sheet during stamping can be reduced, thus ensuring processing accuracy. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment: a high-precision metal stamping die processing device with a stable structure, including a lower die base 1, an upper die base 2, a die cavity 101, a punch 201, a positioning assembly, and a clamping assembly. The die cavity 101 is fixedly installed above the lower die base 1, and the punch 201 is fixedly installed below the upper die base 2, with the punch 201 located above the die cavity 101 and corresponding to it. A support block 301 is fixedly installed on one side of the die cavity 101, and a stop block 304 is fixedly installed on the other side of the die cavity 101. The support block 301 is flush with the surface of the die cavity 101, and the stop block 304 is slightly higher than the die cavity 101. Two sets of first springs 302 are fixedly installed above the lower die base 1, and the support block 301 is located between the two sets of first springs 302. A first pressure plate 303 is fixedly installed. The lower surface of the first pressure plate 303 is an arc-shaped structure. The positioning component is set above the die 101, and the clamping component is set below the upper die base 2. There are two sets of clamping components. The metal sheet can be supported by the support block 301. The first pressure plate 303 is installed by the first spring 302. The first pressure plate 303 can work with the support block 301 to clamp and fix the metal sheet. The first spring 302 can provide pressure to the first pressure plate 303. It can adapt to metal sheets of different thicknesses, making it more versatile. The lower surface of the first pressure plate 303 is arc-shaped, making it easier to pull the metal sheet after stamping. The stop block 304 limits one end of the metal sheet to ensure the stability of the metal sheet.

[0023] Please see Figures 1-2 In this embodiment, a discharge port 103 is provided on one side of the lower die holder 1, which communicates with the die cavity 101. A guide plate 104 is provided inside the discharge port 103. The stamped finished product can be discharged by setting the discharge port 103, and the discharged finished product can be guided by the guide plate 104 for easy removal. Two sets of guide pillars 102 are fixedly installed on the upper part of the lower die holder 1, and two sets of guide sleeves 202 are fixedly installed on the lower part of the upper die holder 2. The two sets of guide sleeves 202 are located on the periphery of the two sets of guide pillars 102, and the guide sleeves 202 and guide pillars 102 are slidably connected. The guide sleeves 202 and guide pillars 102 can ensure the precise movement and positioning of the upper die holder 2 during the stamping process.

[0024] Please see Figures 3-4In this embodiment, the positioning component includes a positioning plate 401 and a strip hole 402. Two sets of positioning plates 401 are provided, positioned above the die 101. Two sets of strip holes 402 are formed on the surface of the positioning plate 401. The positioning component includes a first bolt 403 and a threaded hole 404. The surface of the die 101 has the threaded hole 404. The first bolt 403 is threadedly connected to the die 101 through the bolt hole, and the first bolt 403 passes through the positioning plate 401 through the strip hole 402. Two sets of positioning plates 401 can position both ends of the metal sheet. By setting bolts that pass through the slotted holes 402 and are threaded into the die 101 via the threaded holes 404, the positioning plates 401 can be fixed above the die 101. Loosening the bolts allows the positioning plates 401 to slide through the slotted holes 402, adjusting the distance between the two sets of positioning plates 401 to accommodate metal sheets of different widths. The clamping assembly includes a pre-drilled hole 501, a mounting plate 502, and a second bolt 503, located below the upper die base 2. Multiple sets of pre-drilled holes 501 are provided. A mounting plate 502 is positioned below the upper mold base 2 and is fixedly connected to the upper mold base 2 by second bolts 503. The clamping assembly includes a second spring 504, a second pressure plate 505, and a rubber pad 506. The second spring 504 is fixedly installed below the mounting plate 502, the second pressure plate 505 is fixedly installed below the second spring 504, and the rubber pad 506 is positioned below the second pressure plate 505. The second spring 504 is installed by using the mounting plate 502. The second bolt 503 can fix the mounting plate 502 to the bottom of the upper mold base 2. By setting multiple sets of threaded holes 404, the position of the mounting plate 502 can be adjusted according to the width of the metal sheet. The second spring 504 is used to install the second pressure plate 505. The second pressure plate 505 can press and fix the metal sheet when the upper mold base 2 descends for stamping, making the sheet more stable. The rubber pad 506 is in direct contact with the sheet, which can increase the friction and make the sheet more stable.

[0025] When working, the first pressure plate 303 is pulled up, and the metal plate is passed between the first pressure plate 303 and the support block 301, so that one end of the metal plate contacts the stop block 304. The two sets of positioning plates 401 are adjusted to the two sides of the metal plate and fixed with the first bolt 403.

[0026] After the sheet metal is inserted, the first pressure plate 303 is released, and the first spring 302 provides pressure to the first pressure plate 303, thereby pressing and fixing the metal sheet metal. This can effectively prevent the sheet metal from shifting or warping during stamping. The mounting plate 502 is installed using the appropriate pre-drilled hole 501, so that the second pressure plate 505 is located above the metal sheet metal.

[0027] The upper die holder 2 is connected to an external stamping device to drive the upper die holder 2 to descend for stamping. As the upper die holder 2 descends, the second pressure plate 505 presses the metal sheet, and the second spring 504 retracts, which does not affect the stamping work. At the same time, it can make the sheet more stable and less prone to warping.

[0028] Through the above steps, the support block 301 can support the metal sheet, the first spring 302 can install the first pressure plate 303, the first pressure plate 303 can cooperate with the support block 301 to clamp and fix the metal sheet, the stop block 304 can limit one end of the metal sheet to ensure the stability of the metal sheet, the first spring 302 can provide pressure to the first pressure plate 303, and it can adapt to metal sheets of different thicknesses, thus having higher applicability. This solves the problem that during the processing of stamping die processing device, long metal sheets may be deviated or warped due to the force generated by stamping, which may lead to insufficient stamping processing accuracy of the sheet and high product defect rate.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
