Elasticity, load section ring rake angle portion caused by becket bar is bent into waveform, which is pressed into load section outside, to prolong
Open up, towards the face of hole wall, the edge for being calendered the face to be formed exceeds the bar-shaped body side of becket bar, while also solves
Width only has 1.5mm, and height only has the problem of distortion section for sticking up laterally of 1.8 ~ 2.3mm.
In order to which the face 40 for producing calendering extends expanding plate load section bottom, continuous shirt rim periphery is formed, in lower die
Die hole design when, equipped with the hole that continuous shirt rim periphery is formed when finally being slipped into for the load section of regular polygon ring becket bar
Morpheme limits, and when the load section of regular polygon ring becket bar is finally slipped into lower die topography hole, is set by the shape hole of lower die
Some hole morpheme restriction effects, make both sides calendering produce extension become larger shirt rim and slip into power generation shirt rim formation shirt rim periphery
Certain calendering procedure can also be completed in regular polygon ring blanking, but still need shaping in bending, because
It is to be produced in bending because of angle problem to distort rake angle, so this is the waste made an unnecessary move, therefore pays the utmost attention to use
Bending is synchronously completed with calendering.
In order to prevent bending part stress concentration and crack, in bending, set on multiple bender caputs that its upper mold is equipped with
Have the inclined portion for the round end that R is about 1.0-1.5mm, produce during preventing bending can quadratic extension when the wrinkle that is broken.

The loop-drive of the square strip 201a of 1.5mm × 1.5mm or so, forms total height about 5.3-5.5mm tensioner rings by upper and lower hyperbolic, turns round
Diagonally 60 ° three top three bottoms wait triangle distortion it is wavy, due to for upper and lower two dislocation 60 ° of triangles distort wave gesture
There must be one of them wide-angle corner 201b stuck up laterally of square strip annulus, and this deduction side's bar thickness is upper and lower
Distortion section only has several mm lengths, and only 1.5 mm wides among 60 ° of triangle of two dislocation, and is exactly that this is outside
The presence of side rake angle, hole wall at the sheet material base reaming such as brittleness stone material, ceramic wafer, devitrified glass is directly contacted to distort banding
Load plate weight and wind pressure are come in 502 main force areas, so cause stress concentration, load-carrying stress release, heat expansion cause metal with
It is exactly that this wide-angle rake angle is under the effects such as plate linear expansion coefficient is poor, wind frequency vibrations load, earthquake, plate installation balanced differences
The reason for causing more curtain wall panel to crack.505 secondary pore bottom profile in its Figure 10, just it can be seen that being ground in golden steel diamond
The bottom reaming in the hole that drill bit is ground can about form arc chord angle 504 away from bottom hole at 1.5mm, and the wavy expansion of the prior art
What the wide-angle corner 201b stuck up laterally of 201 surface bottom portion of ring contacted at bottom reaming about forms arc chord angle 504 at 1.5mm
Upper dome (see in Figure 10 at secondary section), thus be easy to cause back of the body bolt tensioner ring and fail to strut completely and cause sleeve to grow
Hidden danger outside hole.
Architectural feature the foregoing is merely the specific embodiment of the present invention, but the present invention is not limited thereto, Ren Heben
The technical staff in field in the field of the invention, all cover among protection scope of the present invention by the change or modification made.
