Specific embodiment
The technical solution of the utility model is described in detail by the following examples, following embodiment is only exemplary
, it is only capable of for explanation and illustration the technical solution of the utility model, and be not to be construed as to technical solutions of the utility model
Limitation.
The application provides a kind of two-way flanging die, as shown in Fig. 4 to Fig. 8, including cope plate 1, the first spring 3, limiting
Screw 4, holding pad 5, upper mold insert 2, lower template 11, lower die insert 7, limiting plate 12, shaft 8, second spring 9 and rotating cavity die
10。
Cope plate 1 installs each component of upper mold, via is provided on cope plate thereon for being connect with lathe upper table surface,
Stop screw passes through via, and the lower end of stop screw is fixedly connected with holding pad.
It passes through cope plate and the first spring with stop screw, and the lower end of stop screw is connect with holding pad, and holding pad is risen
Safe spacing acts on, and the holding pad in top dead-centre is avoided to fall.
Holding pad 5 is rectangular steel plates, and centre processing is fluted, and for installing the first spring, binder is carried out to blank.
First spring 3 is placed on stop screw 4, and between cope plate and holding pad.
Upper mold insert 2 is fixed on cope plate 1；
