Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1 and Fig. 2, the utility model is made up of drift body etc., and the drift body is by the first drift 11,
Small big stepped connection is constituted under successively for one step section 12, second step section 13 and the second drift 14, first punching
First Transition section 21 is provided between first 11 and First stage 12, the diameter of 21 bigger diameter ends of the First Transition section is than the first drift
The 11 big 2cm of diameter；Bevel phase 22, the second step section 13 are provided between the First stage 12 and second step section 13
Diameter 2cm bigger than the diameter in First stage 12；The second transition is provided between the second step section 13 and the second drift 14
Section 23.
First annular groove 41 is provided with First Transition section 21, the edge on the lower end cell wall of the first annular groove 41
Circumferencial direction is uniformly provided with four first step holes 51, and first stage clip is bolted with each described first step hole 51
31, each first stage clip 31 wears out downwards the first step hole 51 of correspondence position, and its external part is emerged First Transition
The correspondence position of section 21；The second annular groove 42 is provided with the bevel phase 22, in the lower end cell wall of second annular groove 42
On be along the circumferential direction uniformly provided with six second step holes 52, is bolted with one second pressure in each described second step hole 52
Spring 32, each second stage clip 32 wears out downwards the second step hole 52 of correspondence position, and its external part is emerged bevel phase
22 correspondence position.First stage clip 31 and the second stage clip 32 implement pressure admittedly in moving process to the correspondence position on workpiece,
Make the Working position held stationary of workpiece.
Connecting plate 61 is installed with the upper end of the stage clip 32 of first stage clip 31 and second, lower end is respectively connected with pressing plate
62, the lateral wall of the connecting plate 61 is provided with screw thread, and the connecting plate 61 is spirally connected and is fixed in the stepped hole of correspondence position；The pressure
The diameter of plate 62 is adapted with the aperture of correspondence position stepped hole, to enter corresponding with the stage clip elastic shrinkage of correspondence position
In stepped hole.
Application method of the present utility model is as follows：
As shown in Fig. 1 to Fig. 2, the first stage clip 31 is lowered into 41 corresponding six first steps of first annular groove successively
It is the second stage clip 32 successively to entering in the corresponding four second step holes 52 of the second annular groove 42 and all solid with upper end in hole 51
The connecting plate 41 of fixed connection is spirally connected and is fixed in corresponding stepped hole.
When starting processing, the first drift 11 goes out aperture, and drift body continues to move down, and First Transition section 21 is touched
The hole wall of machining small, now, six pressing plates 62 of the lower end of the first stage clip 31 are also connected to the week of aperture in First Transition section 31
Enclose, under stamping press effect, First Transition section 21 is moved down, and the aperture of aperture is turned over downwards, now, four the first stage clips
The pressing plate 62 of 31 lower ends is attached on inverted sections all the time, makes turnover process held stationary, to ensure that aperture is indeformable, when drift body
Continue downward, the lower end of the first stage clip 31 in First Transition section 21 is extruded in first step hole 51, the lateral surface of pressing plate 62
When lateral surface with First Transition section 21 is flushed, First Transition section 21 continues to move down, and continues to expand the flanging mouth of aperture
Footpath.
Then, the First stage 12 wear small holes, and then, the second changeover portion 23 touch the flanging bore of machined aperture
Wall, now, the pressing plate 62 of six lower ends of the second stage clip 32 is also connected to around aperture in bevel phase 22, in stamping press effect
Under, bevel phase 22 is moved down, and the aperture of aperture continues to be turned over downwards, and now, the pressing plate 62 of the lower end of the second stage clip 32 is downward
It is mobile to be simultaneously attached on inverted sections all the time, make turnover process held stationary, to ensure that aperture is indeformable, when drift body continue to
Under, the pressing plate 62 of the lower end of the second stage clip 32 is extruded in second step hole 52, the lateral surface of pressing plate 62 and bevel phase 22 at this
Lateral surface when flushing, bevel phase continues to move down with drift body, and continues to expand the flange bore of aperture.
Then, second step section 13 wears and mistake, and due to being to rush macropore by aperture, drift is from bottom to top to gradually reduce to add
Break gap, therefore the flange surplus of second step section 13 is less, less, stability is preferable, finally, by the second drift 14 for deflection
Bar stock cutting by punching, after flange part blanking before, forms the macropore of last processing request, due to the first stage clip 31 and the second pressure
Pressing plate 62 on spring 32 is simply fitted in flange section, by stripper of the flange part of blanking in by mould from drift body
On when taking down, do not have high resistance, the elastic force to stage clip will not also produce considerable influence, simple structure ensureing to process
While surplus, it is ensured that machining accuracy, the process-cycle is reduced, saved cost.
The non-description section of the utility model is consistent with prior art, and therefore not to repeat here.
Implementation method of the present utility model is these are only, the scope of the claims of the present utility model, every profit is not thereby limited
The equivalent structure made with the utility model specification and accompanying drawing content, is directly or indirectly used in other related technology necks
Domain, similarly within scope of patent protection of the present utility model.
