Pin bending device suitable for expanding or narrowing width between pins

Abstract

The invention discloses a pin bending device suitable for expanding or narrowing the width between pins. The pin bending device comprises a rack, a press rod, a deformation press block fixed at the lower end of the press rod, and a material table positioned under the deformation press block, wherein the press rod can move along the axial direction; a pin locking device is also fixed on the press rod; the pin locking device comprises a spring seat, a spring and a locating press block; the spring seat is fixed on the press rod; the two ends of the spring are respectively and fixedly connected with the spring seat and the locating press block; the axis of the spring is parallel to that of the press rod; the position of the lower end of the locating press block is lower than that of the lower end of the deformation press block; the locating press block and the deformation press block are respectively provided with a containing hole; the material table is also provided with a groove adjusting part; a groove is formed between the groove adjusting part and the material table. The pin bending device is simple in structure; after the pin bending device is used, the condition that the matching accuracy between the pins and pin holes are not high due to the change of gaps between the pins caused by bending processing can be avoided; the pin bending device is suitable for expanding or narrowing the width between the pins.

Description

technical field [0001] The invention relates to the field of equipment used in the manufacture of network transformers, in particular to a lead bending device suitable for enlarging or reducing the width of the leads. Background technique [0002] Network transformers are widely used in high-performance digital switches; SDH / ATM transmission equipment; ISDN, ADSL, VDSL, POE power receiving equipment integrated business digital equipment; FILT optical fiber loop equipment; Ethernet switches and other equipment. [0003] The network transformer mainly includes a base, a cover, pins, and coils arranged between the pins. At the same time, the pins on the network transformer are generally arranged in two rows. In the prior art, the pins on the packaged network transformer are mostly needle-shaped. However, in practical applications, since the pin holes configured for the pins have different widths, it is often necessary to bend the pins to change the width between two rows of pin...
