Abstract
The invention relates to a swaging mechanism for improving for improving forming height and precision of a hole flanging. The swaging mechanism for improving the moldability of the hole flanging comprises a hole-flanging movable swaging block, a transmission rod member, a pressure source, a hole-flanging terrace die member, a drive and a hole-flanging cavity die; the hole-flanging terrace die penetrates through a lower swaging plate to be installed on a lower die and the hole-flanging cavity die is installed on an upper die split-type embedding block; the drive is an upper sliding block of a punching device and a front end spherical surface of the transmission rod member is contacted with a bottom spherical surface of the hole-flanging movable swaging block; the pressure source transmits the power to the hole-flanging movable swaging block through the transmission rod member; the hole-flanging movable swaging block and the hole-flanging terrace die press a punching part and move upward to enter the hole-flanging cavity die; and the hole-flanging movable swaging block does reciprocated movements in the hole-flanging cavity die along the axial direction of the hole flanging. The swaging mechanism provided by the invention solves the problem that an opening part is cracked and darkly cracked, is coarse and the like; the swaging mechanism improves the moldability of the hole flanging, the precision of the hole flanging and the quality of the opening part of the hole flanging.
Description
technical field [0001] The invention is suitable for vertical and non-perpendicular hole-turning mold mechanisms for automobiles and hardware parts, especially a pressing mechanism for improving the height and precision of hole-turning and its application. Background technique [0002] With the development of the automobile industry and the maturity of the stamping process, the shape of the parts is becoming more and more complex, and the precision requirements are constantly improving. The blanks with a tensile strength above 480MPa are directly turned out on the stamping die and the height of the hole is required to be greater than 15mm, which cannot be realized in the prior art. Contents of the invention [0003] The purpose of the present invention is to solve the problems of high hole turning height, high hole turning precision, high tensile strength of the blank, and improvement of hole turning quality. [0004] The technical scheme that solves the above-mention...
