Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
Example one
An adjustable flaring die as shown in fig. 1-3, comprising an upper die 2 and a lower die 11, characterized in that: the upper die 2 comprises an upper die plate 3, an upper die core 4 fixedly arranged at the bottom of the upper die plate 3 and an upper adjusting ring 9 detachably sleeved on the outer side of the upper die core 4, the lower part of the outer side surface of the upper die core 4 is a first conical surface 7 for flaring guide, the lower die 11 comprises a lower die plate 12, a lower die core 13 fixedly arranged at the top of the lower die plate 12 and a lower adjusting ring 18 detachably sleeved on the outer side of the lower die core 13, and the upper part of the outer side surface of the lower die core 13 is a second conical surface 16 for flaring guide.
Chamfers for abutting against the upper end surface and the lower end surface of the rim are respectively arranged at the joint of the lower end surface of the upper adjusting ring 9 and the first conical surface 7 and the joint of the upper end surface of the lower adjusting ring 18 and the second conical surface 16. The thicknesses of the upper adjusting ring 9 and the lower adjusting ring 18 are both 30-50 mm.
