Description

Technical Field

[0001] This utility model relates to the field of rectifier bridge processing technology, and in particular to a bending corner forming device for an engine rectifier bridge. Background Technology

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

[0003] In the prior art, Chinese patent application number 202023330432.9 discloses a rectifier bridge pin bending device. This utility model's rectifier bridge pin bending device, by setting a lower pressure roller tangent to its top surface on the base, allows the pins to undergo a flexible and gentle bend under the pressure of the upper pressure roller of the die and the lower pressure roller of the base. This avoids damage or destruction to the pin plating during the bending process, ensuring that the bent pins have a neat appearance and reliable strength. Simultaneously, because the stress at the bend point is evenly distributed during the bending process, vibration is minimal, ensuring the safety of the chip inside the rectifier bridge and improving the operational reliability of the rectifier bridge. Furthermore, this utility model also considers the problem of bending errors caused by the rectifier bridge body flipping during the bending process, and sets a limiting pressure plate to constrain the position of the rectifier bridge, ensuring precise control of the pin bending angle.

[0004] However, the above-mentioned technical solutions have the following drawbacks: the groove shape on the base is fixed, which can only accommodate a single rectifier bridge for placement and positioning, resulting in low applicability. Furthermore, bending the rectifier bridge pins requires manual pressing, which is time-consuming and labor-intensive, making it inconvenient for mass production. Therefore, this application proposes a bending corner forming device for engine rectifier bridges to solve the above problems. Utility Model Content
