Switch shrapnel forming die and forming method thereof

Abstract

The invention relates to a switch pop-up piece forming die and a forming method thereof. The forming die comprises an upper die body and a lower die body. A first blanking station, a second blanking station, a third blanking station, an opening bending station, a clamping edge bending station, a side wall pre-bending station, a shaping station and a discharging station are sequentially arranged between the upper die body and the lower die body from left to right. The lower die body is provided with a first countersunk groove in the shaping station, the first countersunk groove is provided with an elastic supporting block in the middle and swing blocks located on the two sides of the elastic supporting block and swinging to the middle, the upper die body is provided with a second countersunk groove in the shaping station, and a pair of pressing blocks are arranged on the second countersunk groove. The die is novel in structure and reasonable in design, the machining stations are arranged on the die so that multiple procedures can be completed through one time of die assembly, a machined switch pop-up piece is obtained at the last station, not only is machining efficiency high, but also product precision is high, and the rejection rate is reduced.

Description

technical field [0001] The invention relates to a mold for forming a switch elastic piece and a forming method thereof. Background technique [0002] A switch shrapnel, its structure is as Figure 1~2 As shown, the existing stamping die has a simple structure and a single function, and only one process can be completed for each mold clamping stamping. To complete the processing of switch shrapnel with multiple processing processes, it is necessary to use multiple sets of molds to complete all processes, which not only has low productivity , and the production cost is high. Contents of the invention [0003] In view of this, the object of the present invention is to provide a mold for forming a switch elastic piece and a forming method thereof, so as to improve the processing efficiency and product precision of the switch elastic piece. [0004] The technical solution adopted in the present invention is: a mold for forming switch springs, including an upper mold and a lowe...
