Embodiment 1
[0046] Example 1. A low-voltage circuit breaker energy storage lock processing technology, such as Figure 1-4 shown, including the following steps:
[0047] a. Punch guide pinholes and flashes: punch out the upper edge 1 flash of the part, and punch guide pinholes 9 on the strip at the same time;
[0048] b. Leveling: ensure the perpendicularity between the unfolded part plane and the cylinder 2;
[0049] c. Forming: forming the cylinder 2 to ensure the diameter and shape tolerance of the cylinder 2;
[0050] d. Edge trimming: punching the left edge 3 and the right edge 4 of the unfolded part at the same time;
[0051] e. Bending: bend the upper right corner of the unfolded part to form a warping angle 5;
[0052] f. Trimming: Die-cut the lower edge 10 of the unfolded part, and reserve the connecting rib 6 to connect with the strip material;
[0053] g. Forming and bending: bending and forming the unfolded parts to form bent parts;
