Description

Technical Field

[0001] This utility model relates to the field of tooling equipment, specifically to a composite stamping die tooling. Background Technology

[0002] In traditional compound stamping dies, as the material is continuously stamped into finished products, its position extends forward. Because the material area is much larger than conventional dimensions, stability issues arise as it extends forward. Specifically, when a large sheet material is pushed along the die's direction of travel, its front end is prone to sagging due to its own weight and lack of effective support. Simultaneously, the rear end of the material tends to tilt upwards, severely impacting the overall stability of the material on the horizontal plane.

[0003] This phenomenon is particularly pronounced in soft metal materials (such as aluminum alloy sheets and thin steel sheets) due to their poor rigidity and susceptibility to deformation. When the front end of the material sags, it not only affects the accuracy and quality of subsequent stamping but also causes changes in the gap between the die and the material, potentially leading to die damage or workpiece scrap. Furthermore, the tilting of the rear end of the material also affects the accuracy and smoothness of feeding, increasing uncertainties in the production process.

[0004] This material stability issue directly affects the accuracy, efficiency, and consistency of stamping quality, and is a technical problem that urgently needs to be solved in the design of traditional composite stamping die tooling.

[0005] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0022] like Figure 1-3As shown, a composite stamping die fixture includes: an upper die base 100, a top plate 200, a mounting plate 300, a slider 400, a base plate 500, a top post 600, a first die cavity 700, a first punch 800, a lower die base 900, a second die cavity 1000, a limiting post 1100, a lower die connecting post 1200, a guide post 1300, a second punch 1400, and a support base 1500. The upper die base 100 is connected to a stamping device, and the upper die base 100 is connected to the top plate. A 200 connection is made, with the top plate 200 connected to the mounting plate 300. The mounting plate 300 has a mounting groove 310, and the slider 400 is located within the mounting groove 310. The thickness of the slider 400 is less than the thickness of the mounting groove 310. The bottom plate 500 is located below the mounting plate 300 and has a bottom plate hole 510. The first die 700 is located below the bottom plate 500 and is connected to one end of the guide post 1300 during use. One end is connected to the lower mold base 900 and the second die 1000 respectively. The first die 700 is connected to the first punch 800. The first punch 800 is connected to the first die 700 and the bottom plate hole 510 through the top post 600. The lower mold base 900 and the second die 1000 are provided with grooves that match the first punch 800 and the second punch 1400. The lower mold base 900 is provided with a lower mold connecting post 1200 and a guide post 1300. The lower mold base 900 is connected to the lower mold through the lower mold The connecting post 1200 and the guide post 1300 are connected to the second die 1000. The lower die base 900 is provided with a limiting post 1100. The second punch 1400 is located in the groove of the second die 1000. The thickness of the second punch 1400 is greater than the thickness of the second die 1000. The second punch 1400 is provided with a second punch hole 1410. When in use, the second punch hole 1410 is connected to the top post 600. The support base 1500 is connected to the second die 1000.

[0023] like Figure 4 As shown, the support base 1500 includes a support base 1510 and a support rod 1520. The support base 1510 is provided with a base hole 1511, which is connected to the top column 600 when in use. The support rod 1520 is connected to the front end of the support base 1510. The included angle between the support rod 1520 and the support base 1510 is 30°. The support rod 1520 is arranged symmetrically on the left and right sides.

[0024] The method of using this utility model is as follows: The stamping equipment presses downward through the upper die base 100. The upper die base 100 drives the top plate 200, the top plate 200 drives the mounting plate 300, the mounting plate 300 drives the bottom plate 500, and the bottom plate 500 drives the first die cavity 700. Subsequently, the first die cavity 700 inserts into the guide post 1300, so that the entire upper die structure, along the guide post 1300, cooperates with the lower die structure to stamp the material. During the stamping process, the material is first restricted by the limiting post 1100 within the specified space on the lower die base 900. The first punch 800 and the second punch 1400 stamp the material from the upper and lower directions respectively. During this process, the first punch 800 will extend and retract upward along the first die cavity 700. The extension and retraction path depends on the top post 600, and the extension and retraction space comes from the mounting groove 310. The top post 600 will penetrate the bottom plate 500 and the bottom plate hole 510 and push upward to create the space between the thickness difference of the mounting groove 310 and the slider 400, which serves as a buffer space for the first punch 800. On the other hand, the ejector pin 600 penetrates the second punch hole 1410 of the second punch 1400, causing the second die 1000 to move downward along the guide pin 1300. Under this dual action of up and down, the material can be stamped into the preset structure and shape.

[0025] Finally, after a product is completed, the material will be pushed forward. At this time, the material can use the support rod 1520 as a support platform. The distance between the two symmetrical support rods 1520 is less than the width of the material. In this way, the bottom of the material can be placed on the support rod 1520, ensuring that the material has enough space and remains horizontal. The horizontal position can ensure the stability of the material position during processing, thereby achieving the precision requirements of the stamping process.

[0026] Compared with traditional technologies, this utility model addresses the problem of needing sufficient stable space when processing sheet materials with composite stamping die tooling. Through the design of the support base, it provides stable support and guiding space, ensuring the stability of materials during processing.

[0027] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
