Detailed Description

The present invention will be further explained with reference to the following embodiments and accompanying drawings.

In the embodiment, as shown in FIGS. 3 to 7: a long-edge chamfering die comprises a die carrier consisting of an upper die plate 1, a lower die plate 2, a guide pillar 3 and a guide sleeve 4, wherein a chamfering upper die 5 and a chamfering lower die 6 are respectively arranged on the upper die plate 1 and the lower die plate 2; two parallel limiting bulges 601 are arranged on the lower chamfering die 6 corresponding to two sides of the conductive copper bar 01, the thickness of each limiting bulge 601 is smaller than that of the conductive copper bar 01, and a limiting notch 602 is arranged on each limiting bulge 601 corresponding to a side bulge 02 of the conductive copper bar 01; the chamfer upper die 5 is provided with a chamfer bulge 501 corresponding to the chamfer edge 03 of the conductive copper bar 01 and an upper groove 502 corresponding to the bent parts at the two ends of the conductive copper bar 01. The limiting protrusion 601 of the lower chamfering die 6 has a limiting effect on the conductive copper bar 01 and also serves as a forming die of the chamfering edge 03, so that the feeding and discharging are convenient, the chamfering consistency of the long edge is good, the forming effect is good, and the uniform and consistent chamfering forming of the conductive copper bar 01 on the longer edge is realized. In addition, the limiting notch 602 plays a role in assisting in limiting the conductive copper bar 01, and the positioning accuracy is further ensured.

In the embodiment, as shown in FIGS. 3 to 7: the lower chamfer die 6 is provided with a lower groove 603 corresponding to the bending parts on two sides of the conductive copper bar 01. The lower groove 603 of this embodiment is used for accommodating the bending portions on both sides of the conductive copper bar 01, and the processing thereof can satisfy the placing of the conductive copper bar 01.

In the embodiment, as shown in FIGS. 3 to 7: the deviation between the distance between the two limiting protrusions 601 and the width of the conductive copper bar 01 is 0-0.15 mm.
