Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Embodiment
As it is shown in figure 1, this utility model provides a kind of drift once-forming for automobile formwork parts piercing and flanging, it is used for
Punching during plate stamping and flange, including jumper bar 1 and the drift being arranged on described jumper bar 1 top, described drift includes
Punching portion and turn-up portion 2, described turn-up portion 2 is in cone, in order to make sheet material good looking appearance after flange, so by described cone
Tangent line be designed as arc shaped, the big nose circle of described cone turn-up portion 2 is connected with described jumper bar 1, described conical turn-up portion 2
Little nose circle be provided with described punching portion.In blanking process, first by the punching portion of front end, sheet material gone out hole, then by punching portion
Rear end to plate flanging forming, in operation without more mold exchange, effectively reduces operation with the turn-up portion 2 of moulding
Arrangement, and completes punching and two actions of flange in a stamping-out, it is ensured that the positional precision of flanging bore, it is to avoid two
The precision impact that secondary punching press brings.
Described punching portion includes the 32, second punching portion 33 of the first punching portion and semicircle 31, described second punching portion 33
Being arranged on the little nose circle of cone turn-up portion 2, described first punching portion 32 is positioned at the top in described second punching portion 33, and described the
