[0028] like Figure 1 and Figure 2 As shown, this application provides a stamping forming die, including a lower die base 1 and an upper die base 2 for connection with the output shaft of a punch press. The top of the lower die base 1 is provided with a support assembly 3 for placing stamped parts, and the bottom of the lower die base 1 is provided with a stamping assembly 4. The stamping assembly 4 cooperates with the support assembly 3 to stamp and form the stamped parts placed on the support assembly 3. The support assembly 3 includes a lower die plate 31, a plurality of support nuts 32 and a plurality of support screws 33. The lower die plate 31 is fixed to the top of the lower die base 1, and the plurality of support nuts 32 are fixed in a ring on the top of the lower die plate 31. The support screws 33 correspond one-to-one with the support nuts 32 and are threadedly connected to the support nuts 32. The lower die plate 31 below the support nuts 32 is provided with a lower clearance hole 311 adapted to the support screws 33. In use, the support screws 33 are adjusted to fit the support nuts 32. The position of the support screw 33 is adjusted, thereby changing the height of the top of the support screw 33 extending out of the lower template 31. Then, the stamping part to be stamped and shaped is placed on top of multiple support screws 33. The height of the support point at the top of the support screw 33 is then finely adjusted to provide appropriate support for the stamping part. The press is started, and the upper die holder 2 moves downward under the drive of the press output shaft. At this time, the stamping assembly 4 moves downward along with the upper die holder 2, and cooperates with the support assembly 3 to apply pressure to the stamping part placed on the support assembly 3. The support screw 33 in the support assembly 3 provides support force for the stamping part and interacts with the pressure of the stamping assembly 4, thereby realizing the stamping and shaping of the stamping part. Compared with the existing technology, it can flexibly adjust the height of each support point according to the shape, thickness and other requirements of different stamping parts, improve the adaptability of the mold to diversified products, improve the versatility, and reduce the customization cost.
[0029] like Figure 1 and Figure 2As shown, the stamping assembly 4 includes an upper template 41, multiple stamping nuts 42, and multiple stamping screws 43. The upper template 41 is fixed to the bottom of the upper die base 2. The multiple stamping nuts 42 are fixed in a ring shape to the bottom of the upper template 41. The stamping screws 43 correspond one-to-one with the stamping nuts 42 and are threadedly connected to them. Above the stamping nuts 42, on the upper template 41, there is an upper clearance hole 411 that matches the stamping screws 43. The stamping screws 43 correspond one-to-one with the support screws 33. In use, by rotating the stamping screws 43, the position of the stamping screws 43 in the stamping nuts 42 can be adjusted, thereby adjusting the length of the lower end of the stamping screws 43 extending out of the upper template 41. After the stamped part is placed... Afterwards, the relative positions of the stamping screw 43 and the support screw 33 can be pre-adjusted according to the specific conditions of the stamped parts to prepare for stamping and shaping. After the press is started, the output shaft of the press drives the upper die holder 2 and the upper template 41 fixed at its bottom to move downwards. At this time, the stamping screw 43, which is threadedly connected to the stamping nut 42, moves downwards along with the upper template 41. The lower end of the stamping screw 43 gradually approaches and finally contacts the stamped parts placed on the support assembly 3. Under the joint action of the stamping screw 43 and the support screw 33, pressure is applied to the stamped parts. Since the stamping screw 43 and the support screw 33 correspond one-to-one, pressure can be applied evenly at different positions of the stamped parts to achieve precise stamping and shaping of the stamped parts.
[0030] like Figure 1 and Figure 2 As shown, multiple guide posts 5 are fixedly provided at the bottom of the upper template 41, and guide holes 312 corresponding to the guide posts 5 are provided on the lower template 31. The guide posts 5 can be inserted into the guide holes 312. When the lower template 31 on the lower die base 1 approaches the upper template 41, the guide posts 5 will align with the corresponding guide holes 312 on the lower template 31 and be inserted into them. Through the cooperation of the guide posts 5 and the guide holes 312, the movement trajectory of the upper template 41 can be precisely restricted, so that the upper template 41 will not deviate or shake during the stamping process. This helps to ensure stamping accuracy and avoid quality problems such as deviation and deformation of stamped parts caused by inaccurate alignment of the upper template 41 and the lower template 31, thereby improving the product qualification rate and consistency. Specifically, there are four guide posts 5, which are respectively set at the four corners of the upper template 41.
[0031] like Figure 1 and Figure 2As shown, the bottom of the upper die holder 2 is fixed with multiple upper limit posts 6, and the top of the lower die holder 1 is fixed with multiple lower limit posts 7. The upper limit posts 6 and the lower limit posts 7 correspond one-to-one. The lower end of the upper limit post 6 can abut against the upper end of the lower limit post 7. When the press drives the upper die holder 2 to move downward, the upper limit posts 6 also move downward synchronously. When the stamping is close to the completion stage, the lower end of the upper limit post 6 gradually approaches the upper end of the lower limit post 7 until the two abut against each other, preventing the upper die holder 2 from moving further downward. This limits the minimum distance between the upper die holder 2 and the lower die holder 1, and avoids damage to the stamped parts and the die caused by over-stamping. Specifically, there are four upper limit posts 6, symmetrically arranged on the upper die holder 2, and four lower limit posts 7, symmetrically arranged on the lower die holder 1.
[0032] like Figure 1 As shown, the lower template 31 is provided with multiple insertion holes (not shown in the figure), and limiting members 8 are inserted into the insertion holes. The multiple limiting members 8 surround the limiting area of the stamping part. Before the stamping operation, the limiting members 8 are inserted into the corresponding insertion holes of the lower template 31 according to the shape and size requirements of the stamping part. These limiting members 8 surround the limiting area of a specific shape to provide an accurate placement position for the stamping part. After the stamping part is placed in the limiting area, the limiting members 8 can prevent the stamping part from shifting in the horizontal direction during the stamping process, ensuring that the stamping part is always in the predetermined position during the stamping process and precisely cooperates with the upper die stamping assembly 4, thereby ensuring the accuracy of stamping and shaping.
[0033] like Figure 3 As shown, the lower end of the limiting member 8 is provided with a plug-in part 81, which is adapted to the plug-in hole. The limiting member 8 is plugged into the plug-in hole through the plug-in part 81, which facilitates the assembly and disassembly of the limiting member 8. The limiting member 8 can be quickly inserted into the appropriate position according to the contour of the stamping part. Specifically, there are eight limiting members 8, with two corresponding to the four corners of the stamping part.
[0034] like Figure 1 and Figure 2 As shown, both the support screw 33 and the stamping screw 43 are rubber-coated screws. Specifically, polyurethane blocks are wrapped around the top of the support screw 33 and the stamping screw 43, which can effectively absorb impact force during the stamping process and reduce damage to the stamped parts and the mold.
[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
