Description

Technical Field

[0001] This utility model belongs to the field of stamping processing technology and relates to a double-material strip riveting mold structure for mechanical keyboard springs. Background Technology

[0002] In the traditional production process of mechanical keyboard springs, the riveting of silver points is mostly carried out using single-process molds or manual assistance. Single-process molds require repeated transfer of material strips between different molds, which not only leads to low production efficiency but also causes cumulative errors due to multiple positioning, making it difficult to guarantee the positional accuracy of the silver points. Manual feeding and riveting methods have problems such as high labor intensity, poor production continuity, and product quality is significantly affected by human factors, making it difficult to meet the needs of large-scale, high-precision production.

[0003] In addition, in the existing technology, the silver wire feeding system is relatively independent from the stamping station, and the silver wire cutting and riveting processes are separated, which increases the equipment footprint and cost. At the same time, frequent downtime for material replenishment can easily cause processing interruptions, resulting in reduced production efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A mold structure for riveting two strips of springs in mechanical keyboards includes: a mold body, on which two sets of processing channels are provided;

[0006] The processing channel has a plurality of punching and forming stations along its processing feed direction for realizing forming processing;

[0007] The blanking and forming station includes a silver dot forming station for processing the silver dot on the spring sheet; the mold body is also equipped with a wire feeding station for feeding material to the silver dot forming station.

[0008] As a further embodiment of this utility model: the wire supply station is located at the side end of the processing channel and is distributed perpendicular to the processing channel; the wire supply station includes: a wire feeding groove extending towards the processing channel, and a plurality of wire seats are provided in the wire feeding groove, which together form a wire feeding path for guiding the wire feeding.

[0009] As a further embodiment of this utility model: the two sets of processing channels are arranged in an adjacent structure, and the upper and lower ends of the two sets of processing channels are respectively provided with a complex array of guide seats for guiding the material strip.

[0010] As a further embodiment of this utility model: the punching and forming station includes a slider processing station for realizing lateral processing; the slider processing station includes: a forming seat for realizing lateral processing, a slider for driving the forming seat to move towards the processing channel, and a wedge block for driving the slider to work.

[0011] The beneficial effects of this utility model are as follows: By setting two sets of processing channels and multiple punching and forming stations on the mold body, this utility model integrates multiple processes such as punching and riveting of mechanical keyboard springs into a single mold, realizing continuous stamping processing. Compared with traditional single-process molds, this significantly improves production efficiency and reduces processing time. The integrated design of the silver dot forming station and the wire feeding station allows the feeding, riveting, and cutting of silver wire to be completed automatically within the mold, avoiding positioning deviations caused by inter-process transfers, effectively improving product processing accuracy and consistency, and ensuring product quality.
