[0002] As a power component, the rectifier bridge is widely used in various power supply devices. In the switching power supply, the rectifier bridge is used to rectify and filter the AC power into DC power. The performance of the rectifier bridge directly affects the reliability of the switching power supply. Therefore, the quality control of the rectifier bridge is very important.

[0003] The shortcomings of the prior art: One of the production processes of the rectifier bridge is to bend the pins on its outer side. Chinese patent 201721851271.3 discloses a rectifier bridge pin bending device, which limits the pins of the rectifier bridge to the side notch of the lower mold, and presses the upper mold from the top, so that the 90° bending of the pins is achieved under the cooperation of the upper and lower molds. However, this bending device has the following defects: first, during the bending operation, the rectifier bridge body is prone to flipping under the action of shear force, causing the bending angle to deviate; second, the stress concentration at the contact part between the pin and the lower mold is likely to cause the pin plating to be scratched or fall off under the action of extrusion, reducing the aesthetics and mechanical strength of the pin; third, the strong vibration caused by the shear force of the upper and lower molds on the pins is transmitted to the inside of the rectifier bridge, which is likely to cause damage to the chip, thereby affecting the electrical performance reliability of the rectifier bridge; fourth, there is no fixing mechanism for the rectifier bridge when processing the rectifier bridge, resulting in the shaking of the rectifier bridge when the pins are sheared.
