Detailed Description

The embodiment of the utility model discloses a flaring and flanging tool for a bushing of a hand-held squeeze riveter, and the flaring and flanging tool is described in detail below with reference to the accompanying drawings.

The embodiment of the utility model discloses a bushing flanging tool for a hand-held squeeze riveter, which is shown in fig. 1 and 2.

A bushing flaring flanging tool for a hand-held squeeze riveter comprises a first pressing tool and a second pressing tool:

the first pressing tool comprises a first upper die 1 and a first lower die 2;

the second pressing tool comprises a second upper die 3 and a second lower die 4;

the connecting structure part of the first upper die 1 and the second upper die 3 is matched with a hand-held squeeze riveter;

the first working part 1-1 of the first upper die 1 is matched with the second working part 3-1 of the second upper die 3 and the flanging part of the bearing lock bushing;

the connecting structure part of the first lower die 2 and the second lower die 4 is matched with a hand-held squeeze riveter.

Further, the first working part 1-1 and the second working part 3-1 are used for supporting products.

Further, the end of the first working portion 1-1 of the first upper die 1 is provided with a 45 degree bevel, and the contact portion with the product is chamfered.

Further, the end of the second working portion 3-1 of the second upper die 3 has a straight edge of 90 degrees, and the contact portion with the product is chamfered.

The first upper die 1 and the second upper die 3 are of cylindrical structures, the upper part is in a connecting structure form and is matched with the connecting part of the hand-held squeeze riveter, the lower part is a first working part 1-1 and a second working part 3-1, the lower part is provided with an angle bevel edge and a chamfer angle, and the inner cavity structure is used for avoiding a locking pin of the locking body.
