Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a flexible strip continuous stamping die. Background Technology

[0002] In the metal processing industry, continuous stamping of flexible strip is a crucial process that is widely used in automobile manufacturing, electronics, home appliances and many other fields.

[0003] Traditional stamping dies often produce products with large-area thinning, and the rear end of the strip also needs to be formed. The area with material is limited and unstable, and the strip forming is unilateral. The overall pressure on the strip during stamping is not stable and smooth, which leads to low efficiency and low quality of flexible strip during stamping. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a flexible strip continuous stamping die, which solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible strip continuous stamping die, comprising a lower die base and an upper die base. A lower template is fixed to the upper end of the lower die base, and an upper template is fixed to the lower end of the upper die base. A strip is conveyed between the lower and upper templates. Limiting posts are slidably connected to the lower template. An annular groove is formed on the outer side of the upper end of each limiting post, and the annular groove matches the edge of the strip. The limiting posts are arranged in an array on both sides of the strip. A limiting hole is correspondingly formed at the lower end of the upper template. A spring is fixedly connected to the lower end of each limiting post. The upper and lower templates are squeezed when they are closed.

[0006] Furthermore, a groove is provided on the upper end of the strip, and a material groove is provided on the lower end of the upper template. A boss is fixed in the material groove, and the boss is matched with the groove.

[0007] Furthermore, the upper mold base has first guide grooves on both sides of its lower end, and the lower mold base has first guide rods fixed on both sides of its upper end, with the first guide rods matching and corresponding to the first guide grooves.

[0008] Furthermore, a second guide rod is fixedly connected to the lower two sides of the upper template, and a second guide groove is provided on the upper two sides of the lower template. The second guide rod and the second guide groove are matched and correspondingly set.

[0009] Furthermore, multiple grooves with equal spacing are formed on the upper end face of the material strip.

[0010] Furthermore, the upper and lower edges of the annular groove are both rounded.

[0011] Compared with the above-mentioned background technology, the flexible strip continuous stamping die provided in this application includes a stamping die with very mature technology, and a core component with a limiting post and a strip. Its principle relies on the limiting of the strip by the annular groove on the limiting post to ensure stable conveying of the strip during the stamping process. Furthermore, the irregular matching of the groove and the boss can prevent the strip from deviating during stamping, thereby improving stamping efficiency and effect.

[0012] This invention provides a flexible strip continuous stamping die. Compared with the prior art, it has the following advantages:

[0013] This flexible strip continuous stamping die features limit posts that restrict the strip's vertical stamping within the annular groove on the upper sidewall of the limit posts. The strip can also be conveyed through the annular groove. Multiple limit posts with equal spacing ensure stable strip conveying, thus achieving continuous stamping.

[0014] This flexible strip continuous stamping die, by setting bosses and grooves, and matching the bosses in the material groove of the upper die with the grooves on the strip, achieves stable locking of the strip with the upper and lower die plates during stamping, thus making the stamping effect better and more stable.

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a flexible strip continuous stamping die, including a lower die base 1 and an upper die base 3. A lower template 2 is fixed to the upper end of the lower die base 1, and an upper template 4 is fixed to the lower end of the upper die base 3. A strip 5 is conveyed between the lower template 2 and the upper template 4. Limiting posts 10 are slidably connected to the lower template 2. An annular groove 11 is formed on the outer side of the upper end of the limiting post 10, and the annular groove 11 is matched with the edge of the strip 5. The limiting posts 10 are arranged in an array on both sides of the strip 5. A limiting hole 13 is correspondingly formed at the lower end of the upper template 4. A spring 12 is fixedly connected to the lower end of the limiting post 10. The spring 12 is squeezed when the upper template 4 and the lower template 2 are closed. The stamping die is a known existing type. The technology is mature, and the many functions of this stamping die will not be elaborated here. The lower die holder 1 and the upper die holder 3 drive the lower template 2 and the upper template 4 to open and close vertically. The cutter set between the upper template 4 and the lower template 2 thins the strip 5. A limit post 10 that can slide up and down is set at the upper end of the lower template 2. An annular groove 11 is opened on the upper circumference of the limit post 10. The two sides of the strip 5 just match the annular groove 11. When the upper template 4 and the lower template 2 open and close, the limit post 10 is squeezed, and the spring 12 at the lower end of the limit post 10 is compressed and ejects the limit post 10. Then, the limit post 10 and the annular groove 11 eject the strip 5 to achieve the effect of carrying material, which enables the strip 5 to be stamped continuously.

[0024] like Figure 2 and Figure 6 As shown, a groove 16 is provided on the upper end of the strip 5, and a material groove 14 is provided on the lower end of the upper template 4. A boss 15 is fixed in the material groove 14, and the boss 15 is matched with the groove 16. The groove 16 on the strip 5 matches the boss 15 in the material groove 14. In this way, the material shape of the strip 5 can be designed in advance with an interlocking snap-fit ​​form. After the strip is thinned, the boss 15 and the groove 16 are just locked together and locked. After the strip is thinned, the strip 5 becomes a solid whole and plays the role of carrying the material. Then the shape is precision cut and formed.

[0025] like Figure 1 and Figure 3As shown, the upper mold base 3 has first guide grooves 7 on both sides of its lower end, and the lower mold base 1 has first guide rods 6 fixed on both sides of its upper end. The first guide rods 6 and the first guide grooves 7 are matched and correspondingly set. When the upper mold base 3 and the lower mold base 1 open and close, the first guide rods 6 and the first guide grooves 7 are matched and correspondingly set, thereby making the opening and closing of the upper mold base 3 and the lower mold base 1 more stable.

[0026] like Figure 2 and Figure 3 As shown, the lower two sides of the upper template 4 are fixedly connected with the second guide rod 9, and the upper two sides of the lower template 2 are provided with the second guide groove 8. The second guide rod 9 and the second guide groove 8 are matched and correspondingly set. Similarly, when the upper template 4 and the lower template 2 open and close, they are matched with the second guide rod 9 through the second guide groove 8, so that the opening and closing of the upper template 4 and the lower template 2 is more stable.

[0027] like Figure 2 As shown, multiple grooves 16 are continuously and equally spaced on the upper end face of the strip 5; the multiple grooves 16 are formed on the strip 5, thereby matching the strip 5 with the upper template 4 and the lower template 2 to continuously feed material, achieving a stable continuous stamping effect.

[0028] like Figure 5 As shown, the upper and lower edges of the annular groove 11 are rounded; the rounded edges of the upper and lower edges of the annular groove 11 are designed to avoid damaging the upper and lower surfaces of the conveyor belt 5.
