Detailed Description

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

As shown in figures 1-5, the flange flanging tool comprises:

the utility model provides a flange turn-ups frock, includes: arranged in sequence

The lower die 3 comprises a lower die body 31 and supporting legs 32 arranged below the lower die body 31, and an accommodating cavity 33 is formed in the lower die body 31;

the pressing plate 2 is arranged on the upper surface of the lower die 3, and the shape of the pressing plate 2 is consistent with that of the upper surface of the lower die 3;

the pressing head 1 comprises a first part 11 and a second part 12, wherein the first part 11 extends into the accommodating cavity of the lower die body 31, and the side wall of the second part 12 is in contact with the pressing plate 2; the first part 11 and the second part 12 are integrally formed, the first part 11 is circular, the upper part of the second part 12 is cylindrical, the lower part of the second part 12 is circular truncated cone-shaped, and the contact position of the first part 11 and the second part 11 is an arc-shaped contact surface. So set up, at the turn-ups in-process, can carry out effectual turn-ups to the work piece.

And the clamping device 4 is used for clamping and fixing the pressure plate 2 and the lower die 3.

Plastics mould, plastics are in the mould shaping back, cut into required loop configuration after, still need to shape loop configuration after high temperature softens the back, and it has certain radian to stereotype the inboard, to keeping away from the crooked structure of loop configuration direction, through the final product of manual treatment out among the prior art, the demand can not be satisfied to the structure, and the process is complicated moreover, and efficiency is underneath.

For this, the utility model discloses a flange turn-ups frock, carry out high temperature heat softening through the flange work piece stock 5 with plastics, then take out, place heat softening's flange work piece stock 5 on lower mould 3, because the diameter that the lower mould held the chamber is greater than the internal diameter of flange work piece stock 5, the external diameter of lower mould upper surface equals the external diameter of flange work piece stock 5, place pressure head 1, part 11 stretches into the intracavity that holds of die body 31 down this moment, carry out the orientation to the internal diameter limit of flange work piece stock 5 and hold impressing of intracavity, the turn-ups on the internal diameter limit of flange work piece stock 5 has been realized.

Since the outer diameter of the second part 12 is slightly larger than the inner diameter of the accommodating cavity, the diameter of the second part 12 is larger than that of the first part 11. And then the pressing plate 2 is placed on the lower die 3, at the moment, the pressing plate 2 is in contact with the outer edge of the flange workpiece blank 5, the clamping device 4 is used for clamping the pressing plate 2 and the lower die 3, and the operation is completed by screwing. After cooling and shaping, loosening and taking out the blank 5 of the flange workpiece, namely completing the flanging process.
