Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a T-shaped tantalum cap continuous strip deep drawing integral forming mold. Background Technology

[0002] Tantalum capacitors are small-sized capacitors with high capacitance, offering excellent frequency and stability, and are suitable for applications such as power supply filtering and AC bypass. The caps used in tantalum capacitors are manufactured using multiple sets of single-station dies for stamping or deep drawing.

[0003] like Figure 1 The image shows a tantalum cap, which, during processing, as follows: Figure 2 The image shows a T-shaped tantalum cap produced by continuous deep drawing of the strip material. Multiple processes, including punching, deep drawing, shaping, punching, and blanking, are completed on a single mold. In contrast, existing tantalum cap production involves multiple sets of molds for stamping and deep drawing, each step requiring manual handling and positioning, resulting in low efficiency and unreliable precision. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a T-shaped tantalum cap continuous strip deep drawing integral forming mold, which solves the problems of low efficiency and lack of guaranteed precision in the existing tantalum cap production.

[0005] The main contents of this utility model include: a T-shaped tantalum cap continuous strip deep drawing integral forming mold, including: an upper template assembly and a lower template assembly, wherein the upper template assembly includes, from top to bottom: an upper mold base, an upper pad, an upper clamping plate, a stop plate, and a stripper plate, and multiple punches are fixedly arranged at the upper clamping plate, the multiple punches pass through the stop plate and the stripper plate, and the stop plate and the stripper plate are segmented structures;

[0006] The lower template assembly includes, from bottom to top: a lower mold base, a lower pad, and a lower template. The lower template is provided with multiple processes or workstations that match the punch.

[0007] Preferably, the stop plate and the stripper plate are three-section structures, namely the first section, the second section and the third section. The first section is provided with a pre-forming punch, the second section is provided with three drawing punches, and the third section is provided with a shaping punch.

[0008] Preferably, three different types of springs with different elastic forces are respectively provided between the first segment, the second segment, the third segment and the upper mold base.

[0009] Preferably, a spring is provided between the second section and the lower mold base.

[0010] Preferably, a height-equalizing sleeve is provided at the stop plate.

[0011] Preferably, the lower template is provided with multiple guide buoyancy pins.

[0012] Preferably, a pad is provided below the lower mold base.

[0013] Preferably, the height of the foot is adjustable.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention utilizes a segmented mold structure design, enabling preforming, deep drawing, and shaping processes to be performed on the same mold. Compared to existing processes such as punching, deep drawing, shaping, and punching, which require multiple molds, this design not only reduces the number of molds required for each process, thus reducing the use of steel materials, but also reduces the space occupied by the molds. Furthermore, it improves processing efficiency and ensures the precision of the T-shaped tantalum cap. Since tantalum is a rare and precious metal, this design also reduces the production costs for enterprises. Attached Figure Description

[0021] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 3 , Figure 4As shown, a T-shaped tantalum cap continuous strip deep drawing integral forming mold includes: an upper template assembly and a lower template assembly. The upper template assembly includes, from top to bottom: an upper mold base 1, an upper pad 2, an upper clamping plate 3, a stop plate 4, and a stripper plate 5. Multiple punches are fixedly arranged at the upper clamping plate 3. The multiple punches pass through holes at the stop plate 4 and the stripper plate 5. The stop plate 4 and the stripper plate 5 are segmented structures. In this embodiment, they are divided into three independent segments: a first segment 11, a second segment 12, and a third segment 13. A pre-forming punch 14 is provided in the first segment 11, three deep drawing punches 15 are provided in the second segment 12, and a shaping punch 16 is provided in the third segment 13. These punches are used to perform pre-forming, three-stage deep drawing and stamping, and shaping processes on the strip 18, respectively. Three types of springs with different elastic forces are respectively installed between the first section 11, the second section 12, the third section 13 and the upper mold base 1: the first spring 21, the second spring 22 and the third spring 23. According to the different elastic forces, the stamping process of different depths and the reset of the mold station can be realized.

[0023] The three-section structure, combined with the application of spring force, enables the strip to be stamped and formed in different processes, avoiding strip deformation, ensuring the stamping accuracy of the mold, and maintaining the balance of the upper mold plate.

[0024] In this utility model, the upper clamp 3 is used to fix the punch, the upper pad 2 has a large hardness and provides support for the upper clamp 3, and the stop plate 4 and the stripper plate 5 facilitate the stripping of the product 17 after stamping and prevent the product 17 from being carried out.

[0025] The lower template assembly, from bottom to top, includes: a lower mold base 8, a lower pad 7, and a lower template 6. The lower template 6 has multiple acupoints that match the punch. The lower pad 7 has high rigidity and serves to support the lower template 6.

[0026] Furthermore, since the forming force of deep drawing is greater than that of pre-forming and shaping, in order to maintain the stability of the second section 12, a fourth spring 24 is provided between the second section 12 and the lower die holder 8 to buffer the second section 12 and facilitate deep drawing.

[0027] Furthermore, the stop plate 4 is provided with an equal-height sleeve 19 to prevent the product 17 from being over-pressed and damaged, thus providing protection.

[0028] Furthermore, the lower template 6 is provided with multiple guide floating pins 20. The guide floating pins 20 guide the strip 18 on the one hand, and support the strip 18 on the other hand. The strip 18 enters the mold between the stripper plate 5 and the lower template 6, and the top of the guide floating pins 20 extends out of the lower template 6 to support and guide the strip 18.

[0029] In this utility model, a foot 9 is provided below the lower die base 8. The height of the foot 9 is adjustable, which makes it convenient to adjust the overall height of the die and to facilitate the operation of production for different stamping equipment.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
