Furthermore, a first stamping lug, a second stamping lug and a stamping cutter are arranged on the bending male die, and the stamping cutter is positioned between the first stamping lug and the second stamping lug. The design between the first stamping lug and the second stamping lug can simultaneously perform the bending action of the two pressure springs, so that the working efficiency is improved.

Further, the bending female die comprises a first forming cavity and a second forming cavity, the first forming cavity and the second forming cavity are identical in structure, and a cutter groove is formed between the first forming cavity and the second forming cavity; the both sides face of one becomes the die cavity is equipped with the shaping perpendicular, the downside of shaping perpendicular passes through the support frame installation and rotates the shaping module, and the bottom of one becomes the die cavity is located the U-shaped groove that is equipped with between the rotation shaping module. And the forming vertical surface of the first forming cavity is used for one-step forming of the compressed spring plate when the first stamping lug descends, and the plate is continuously pressed down to only rotate the forming module under the action of the first stamping lug, so that secondary forming of the compressed spring is realized.

Furthermore, an extension spring is arranged between the rotary forming module and the bending female die. Due to the design of the extension spring, the rotary forming block can return to the original position after the stamping of the first stamping bump and the second stamping block is finished, and the next stamping of the plate is facilitated.

Further, the rotation forming module comprises an arc rotating portion, the arc rotating portion is embedded into the bending die, and the arc rotating portion is provided with a secondary forming inclined surface and a transition forming surface. The arc rotating part rotates in the bending female die, the secondary forming inclined surface performs secondary forming on the side surface of the plate, and the transition forming surface performs forming on the primary formed pressure spring from two sides of the bottom.

Furthermore, guide rods are arranged on two sides of the upper die base and the lower die base.

Furthermore, a compression spring is arranged on the guide rod. Due to the design of the guide rod and the compression spring, the bending male die can stably fall and rise in the rising and falling processes between the upper die base and the lower die base, and is not easy to deflect.

Above-mentioned technical scheme can see out, the beneficial effects of the utility model are that:

the pressure spring bending multi-station progressive die has reasonable structural design, solves the defects of a single-process die, realizes integration of multiple processes, shortens the processing time and reduces the acquisition cost of the die; during the use, will wait that the panel of bending sends to the die of bending on, the pneumatic cylinder drives the terrace die of bending and moves down, carries out the punching press with panel and bends one shot forming, easy operation, work efficiency is high.
