Abstract
Description
Technical Field
[0001] This utility model relates to the field of progressive die technology, specifically to progressive dies for processing metal bushings of wire connectors. Background Technology
[0002] In the field of electronic equipment and electrical connections, wire connectors are key components for achieving reliable electrical connections, and their performance directly affects system stability. Metal bushings, as components of wire connectors, play a crucial role in enhancing mechanical strength and ensuring conductivity. These bushing products typically have a ring-shaped overall structure, and because they require a certain level of strength, the material thickness used is relatively large for small components.
[0003] Currently, the industry generally employs a combination of machining and manual operation in the production of these metal bushings. Specifically, machining handles the initial shape cutting and dimensional processing, while key processes such as deburring, surface treatment, and precision calibration rely on manual operation. However, this production model has revealed several drawbacks in practical applications: firstly, high manual involvement leads to low production efficiency, making it difficult to meet the demands of large-scale production; secondly, consistency in manual operation is difficult to guarantee, resulting in significant fluctuations in product quality, and the continuous rise in labor costs severely impacts the company's economic benefits. Furthermore, low material utilization and cumbersome process connections during machining further restrict the improvement of production efficiency and the control of production costs.

[0048] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0049] Please see Figure 1-10 This application provides the following technical solutions:
[0050] A progressive die for processing metal bushings of wire connectors includes an upper die 100 and a lower die 200. A conveying system for conveying a material strip 300 is provided between the upper die 100 and the lower die 200. Several workstations are arranged between the upper die 100 and the lower die 200. Furthermore, related structures such as inner guide post assemblies and floating guide assemblies are also provided between the upper die 100 and the lower die 200. Conventional die structures are not the focus of this solution and will not be elaborated upon here. The product 400 to be processed in this application is as follows... Figure 1 As shown, its overall shape is circular. It is necessary to first cut a pattern like this on the 300mm strip. Figure 2 The base material 500 is shown, and then the base material 500 is rolled into a round shape to form product 400. The base material is long and narrow, with structures of approximately ">" shape at both ends, one end convex and the other end concave.
[0051] For ease of explanation, the direction in which the strip 300 moves forward during processing is taken as the front. The workstation group of this progressive die includes, from back to front, the opening workstation 1, the cutting workstation group 2, the forming workstation group 3, the unloading workstation 4, and the waste removal workstation 5.
[0052] The hole-opening station 1 is used to open guide holes on the strip 300; the cutting station group 2 includes several cutting stations, which can cut out long strips of base material 500 corresponding to product 400 from the strip 300; the forming station group 3 includes several rolling stations and a shaping station 34, which can bend the base material 500 into a ring shape; the unloading station 4 can remove product 400 from the strip 300; the waste removal station 5 is used to remove waste from the strip 300.
[0053] With this structural setup, the product 400 to be processed in this solution can be processed using a progressive die, thereby reducing the manual workload and achieving extremely high processing efficiency and stable processing quality.
[0054] Based on the above implementation plan, see Figure 3 The punch at the punching station 1 has two punching sections capable of punching round holes, which can create two circular guide holes on the strip 300. The punch is positioned facing the edge of the strip 300. The guide holes are created at the punching station 1, thereby ensuring the stable position of the strip 300 during subsequent processing, in conjunction with positioning pins and other related structures.
[0055] Based on the above implementation plan, see Figure 4 The cutting station group 2 includes, from back to front, a pre-cutting station 21, a first cutting station 22, and a second cutting station 23. The pre-cutting station 21 performs pre-cutting for subsequent processing, facilitating subsequent material unloading. The first cutting station 22 and the second cutting station 23 work together to cut the base material 500. A detailed description of each station follows.
[0056] The punch corresponding to the first cutting station 22 can cut the base material 500 on the strip 300 at the front and rear sides. The cutting shape of the punch in the first cutting station 22 is a long rectangular strip. The punch in the first cutting station 22 includes a first front cutting part and a first rear cutting part. Figure 4 Taking the direction as a reference, the first front cutting part corresponds to the front cutting area of the base material 500 on the material strip 300 where it is located, that is... Figure 4 The area to the right of the first cutting station 22; the first front cutting part can cut two rectangular through slots on the strip 300, the two rectangular through slots being arranged along the length of the base material 500, i.e. Figure 4 The vertical arrangement shown indicates that the two rectangular through slots cut by the first front cutting part are spaced apart, with the gap located at the center of the front side of the base material 500. The first rear cutting part corresponds to the rear cutting area of the base material 500 on the material strip 300 at its location, i.e. Figure 4 The left side region; the first rear cutting part can cut a rectangular through groove on the strip 300; the length direction of the rectangular through groove cut by the first rear cutting part is parallel to the length direction of the base material 500.
[0057] It should be noted here that the pre-cutting position performed by the pre-cutting station 21 is the position between the two rectangular through slots of the first front cutting part. The pre-cutting station 21 punches at this position to form an hourglass-shaped structure on the material strip 300, which facilitates subsequent material unloading.
[0058] The punch corresponding to the second cutting station 23 can cut both ends of the base material 500 along its length; and the cutting area of the second cutting station 23 on the strip 300 is connected to the cutting area of the first cutting station 22. Through the cutting of the second cutting station 23, the basic shape of the base material 500 can be obtained, and at this time, the right side of the base material 500 and the strip are still connected to a certain extent, which is the processing position of the pre-cutting station 21, thereby ensuring that the base material 500 can move normally with the strip 300.
[0059] A chamfering station is also provided in the first cutting station 22 and the second cutting station 23, which is used to chamfer the reserved position between the two rectangular through slots on the right side of the first cutting station 22.
[0060] Based on the above implementation plan, see Figure 5The forming station group 3 includes a first forming station 31, a second forming station 32, a third forming station 33, and a shaping station 34 arranged sequentially. The final forming of product 400 is carried out in several stations. Bending stress is released through step-by-step forming, and finally, the shaping station 34 completes the adjustment of product 400 to meet mass production stability and ensure product processing quality. The following is a detailed description of each station in the forming station group 3.
[0061] See Figure 7 The punch of the first forming station 31 can punch and roll the base material 500 on the strip 300. The lower die and upper die punch of the first forming station 31 form an arc-shaped rolling structure corresponding to the two ends of the base material 500 in the length direction, which can make the two ends of the base material 500 roll upward.
[0062] Reference Figure 8 In the second forming station 32, the punch, in conjunction with the lower die, stamps and rolls the base material 500 on the strip 300. The lower and upper die punches of the second forming station 32 form an arc-shaped rolling structure corresponding to the two ends and the middle of the base material 500 along its length. The two ends of the base material 500 are rolled upwards along its length, and the middle part forms an arc-shaped protrusion structure from bottom to top. After processing by the second forming station 32, the base material 500 presents an approximately "W" shape.
[0063] See Figure 9 and Figure 10 The third forming station 33 rolls the base material 500 into a ring; the shaping station 34 can round the base material 500 after processing by the third forming station 33, thereby completing the processing of product 400. Because the material of this product is relatively thicker than other small parts, the above three forming stations are used for processing during the forming process, and the bending stress is released in stages to ensure the processing quality of the product.
[0064] Based on the above implementation scheme, the next product station 4 completely removes the area processed by the pre-cutting station 21, allowing the product 400 to detach from the conveyor belt. The waste removal station 5 is used to remove the excess portion remaining on the conveyor belt 300, preventing the continuous forward movement of the conveyor belt 300 from affecting subsequent processing.
