[0053] The utility model provides a method for Figure 1 The wire connector continuous mold is used to process the connecting piece on the material strip. The wire connector continuous mold processes the material strip multiple times continuously, thereby quickly processing the clamping piece. The wire connector continuous mold includes an upper mold assembly and a lower mold assembly. The upper mold assembly is arranged above the lower mold assembly. Figure 1 As shown, a continuous die for a wire connector includes an upper die assembly and a lower die assembly, wherein the upper die assembly is arranged above the lower die assembly.

[0054] like Figure 2 , Figure 3 As shown, the upper die assembly includes an upper die seat, an upper pad, an upper clamping plate, a stop plate, a stripper plate 1, a plurality of first punching upper dies 3, a plurality of punching upper dies 4, and a second punching upper dies 5. The upper die seat, the upper pad, the upper clamping plate, the stop plate, and the stripper plate 1 are arranged in sequence from top to bottom, and the upper ends of the plurality of first punching upper dies 3, the plurality of punching upper dies 4, and the second punching upper dies 5 are arranged on the upper clamping plate, and the plurality of first punching upper dies 3, the plurality of punching upper dies 4, and the second punching upper dies 5 are arranged along the moving track of the material strip according to the forming sequence of the connector. The lower ends of the plurality of first punching upper dies 3, the plurality of punching upper dies 4, and the second punching upper dies 5 pass through the stop plate and are exposed on the lower surface of the stripper plate 1.

[0055] like Figure 4 , Figure 5 , Figure 6 and Fig.11 As shown, the lower die assembly includes a lower template 2, a lower pad, a lower die base, a plurality of first punching lower dies 6, a plurality of punching lower dies 7 and a second punching lower dies 8. The lower template 2, the lower pad, and the lower die base are arranged in sequence from top to bottom. The plurality of first punching lower dies 6, the plurality of punching lower dies 7 and the second punching lower dies 8 are arranged on the lower template 2 along the moving trajectory of the material strip according to the forming sequence of the connecting parts.

[0056] When the upper mold assembly and the lower mold assembly are molded together, the first punching upper mold 3 and the corresponding first punching lower mold 6 cooperate to punch the first end of the connecting part, the punching upper mold 4 and the punching lower mold 7 punch the first end of the connecting part, and the second punching upper mold 5 and the corresponding second punching lower mold 8 cooperate to punch the second end of the connecting part.

[0057] In this embodiment, the upper mold assembly includes multiple first punching upper molds 3, multiple punching upper molds 4 and second punching upper molds 5, and the multiple first punching upper molds 3, multiple punching upper molds 4 and second punching upper molds 5 are arranged along the moving trajectory of the material belt; the lower mold assembly includes multiple first punching lower molds 6, multiple punching lower molds 7 and second punching lower molds 8, and the multiple first punching lower molds 6, multiple punching lower molds 7 and second punching lower molds 8 are arranged along the moving trajectory of the material belt. In this way, during the moving feeding process of the material belt, as the material belt moves, the aforementioned molds on the upper mold assembly and the lower mold assembly gradually process the material belt, and the processing sequence is multiple punching, multiple punching and punching, so as to continuously and quickly process the connector. In this way, in this embodiment, a continuous mold is used to integrate multiple process steps of the connector into the continuous mold, and the connector is quickly produced by the continuous mold, which has lower equipment cost, less manpower required for single equipment plus operation, lower labor cost, continuous and rapid processing, and lower time cost, so that this embodiment has good low-cost characteristics.

[0058] Specifically, the connector produced and processed in this embodiment includes a main body and two clamping pieces, the first end of the main body is a fixed line end, and the second end of the main body is a connecting end. The clamping pieces are arranged on both sides of the fixed line end, and the connecting end is an end for connecting with other structures.

[0059] like Figure 3 As shown, multiple first punching upper dies 3 include a mountain-shaped punching upper die 31 and a middle punching upper die 32, and multiple first punching lower dies 6 include a mountain-shaped punching lower die 61 and a middle punching lower die 62. The mountain-shaped punching lower die 61 is a punching hole die whose shape is compatible with the mountain-shaped punching upper die 31, and the middle punching lower die 62 is a punching hole die whose shape is compatible with the middle punching lower die 62.

[0060] The mountain-shaped punching upper die 31 is set at the position of punching the first end of two adjacent connecting parts, and is used to form the shape of one end and the outer side of the clamping piece. The middle punching upper die 32 is set at the position in the middle of the two adjacent connecting parts, and is used to punch the excess material in the middle of the two adjacent connecting parts and form the shape of the other end of the clamping piece.

[0061] Furthermore, if Figure 3As shown, the plurality of first punching upper dies 3 further include a T-shaped punching upper die 33, which is located upstream of the mountain-shaped punching upper die 31, and the plurality of first punching lower dies 6 further include a T-shaped punching lower die 63, which is a punching hole die that matches the T-shaped punching upper die 33. For the shape of the first end and the outer side of the connector, the present embodiment performs punching in two steps. First, the T-shaped punching upper die 33 and the T-shaped punching lower die 63 are used to perform preliminary contour cutting in the punching area of ​​the mountain-shaped punching upper die 31. The preliminary contour is T-shaped, and the overall area is smaller than the mountain-shaped contour. The processing is performed in several steps to reduce the deformation caused by the processing, so as to facilitate the maintenance of the processed shape.

[0062] In addition, if Figure 3 As shown, the plurality of first punching upper dies 3 further include a trimming upper die 34, which is used to punch out a suitable side shape on the side of the material strip. The plurality of first punching lower dies 6 further include a trimming lower die 64, which is a punching hole die adapted to the trimming upper die 34. The trimming upper die 34 and the trimming lower die 64 are used to punch out the shapes of the edges on both sides of the material strip.

[0063] For the connector in this article, the connector includes a main body and two clamping pieces, the first end of the main body is a wire fixing end, and the clamping pieces are arranged on both sides of the wire fixing end.

[0064] like Figure 2 , Fig. 9 As shown, multiple punching upper dies 4 include a clamping sheet bending upper die 41, and multiple punching lower dies 7 include a clamping sheet bending lower die 71. The clamping sheet bending upper die 41 and the corresponding clamping sheet bending lower die 71 cooperate to bend the clamping sheets so that the two clamping sheets are bent from a state flush with the main body to a state where the two clamping sheets are side by side. Through the aforementioned first punching upper die 3 and the first punching lower die 6, the contour of the connector is punched out on the material strip. At this time, the clamping sheet is still flush with the material strip, or the clamping sheet is flush with the main body. After the clamping sheet bending upper die 41 and the clamping sheet bending lower die 71 cooperate to stamp, the spring sheet is bent to a side-by-side state.

[0065] Specifically, a bending protrusion is provided at the bottom of the clamping piece bending upper die 41 , and a bending groove is provided at the top of the clamping piece bending lower die 71 .

[0066] When the upper mold assembly and the lower mold assembly are molded together for forming, the bending protrusion is embedded in the bending groove, and the two clamping pieces are bent toward each other.

[0067] In addition, if Figure 2 , Fig.10As shown, the plurality of punching upper molds 4 include a clamping sheet secondary bending upper mold 42, and the plurality of punching lower molds 7 include a clamping sheet secondary bending lower mold 72. The bending angle of the clamping sheet is 90 degrees, which is usually difficult to bend sequentially, and the sequential bending angle is usually 80 to 95 degrees. Therefore, in this embodiment, a secondary bending mold is additionally provided, including a clamping sheet secondary bending upper mold 42 and a clamping sheet secondary bending lower mold 72. The clamping sheet secondary bending upper mold 42 and the clamping sheet secondary bending lower mold 72 are bent secondary on the basis of the original bending angle, and the bending angle is further increased to reach 90 degrees or even exceed 90 degrees.

[0068] Specifically, the clamping sheet secondary bending upper die 42 and the clamping sheet secondary bending lower die 72 are similar to the clamping sheet bending upper die 41 and the clamping sheet bending lower die 71 as a whole. The clamping sheet secondary bending upper die 42 has a secondary bending protrusion. Compared with the bending protrusion, the secondary bending protrusion is smaller at the top and larger at the bottom. The clamping sheet secondary bending lower die 72 has a secondary bending groove. Compared with the bending groove, the side wall of the secondary bending groove is more straight as a whole. In this way, the secondary bending protrusion can directly act on the bending part of the clamping sheet, thereby adjusting the bending angle.

Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the plurality of punching upper dies 4 also include two clamping sheet pressing upper dies 43, which are sequentially arranged upstream of the clamping sheet bending upper die 41, and are used to shape the clamping sheet before the clamping sheet is bent.

In the clamping sheet pressing on both sides, the first pressing makes the clamping sheet part bend upward, and the fold of the second pressing is on the aforementioned upward bending part, that is, the clamping sheet is bent upward as a whole first, and then bent downward, so that there is an upward protrusion on the clamping sheet. After the clamping sheet is bent, the two clamping sheets have relative protrusions, which can increase the clamping effect of the clamping sheet.

[0070] In some embodiments of the punching die 4 and the punching die 7, as shown in FIG. Figure 2 As shown, the plurality of stamping upper dies 4 include a connecting piece bending upper die 44 , which is disposed downstream of the clamping piece bending upper die 41 and is used for stamping the main body.

[0071] like Figure 4 , Figure 6 As shown, the plurality of punching lower dies 7 include a connecting piece bending lower die 74, on which a pressing concave die for forming the main body is provided.

[0072] In some embodiments of the second punching upper die 5 and the second punching lower die 8, as shown in FIG. Fig.11 As shown, a rectangular punch 51 is provided on the second punching upper die 5, and the rectangular punch 51 is set at the position between the second ends of two adjacent connecting members. A rectangular punching hole 81 is provided on the second punching lower die 8, and the rectangular punching hole 81 is adapted to the rectangular punch 51, and is used to cooperate with the rectangular punch 51 to punch the excess material between the second ends of two adjacent connecting members.

[0073] The upper die assembly is provided with two rows of production upper die groups, which are symmetrically arranged along the moving track of the material belt, and the production upper die groups include a plurality of first punching upper dies, a plurality of punching upper dies, and a second punching upper dies. The lower die assembly is provided with two rows of production lower die groups, which are symmetrically arranged along the moving track of the material belt, and the production lower die groups include a plurality of first punching lower dies, a plurality of punching lower dies, and a second punching lower dies. The two rows of production upper die groups and the two rows of production lower die groups double the production volume of the continuous die, greatly reducing the production cost.
