Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the present invention is further described.
As shown in Figure 2, material strip pulsed walks in and is arranged in support frame continuous mould, carries out successively the operation that material strip is comprised to following operation on each station of continuous mould:
A, punch out the first middleware g1 at material strip middle part, this first middleware along two longitudinal middle side parts of material strip there is straight flange that length is different, along the horizontal both sides of material strip by symmetrical crimp smooth linking of two ends with described straight flange, form being connected a little of four crimps and straight flange, only in the outside and material strip of straight flange, other parts are banded is connected for the first middleware;
B, at the middle part of the first middleware along laterally even three holes of punching of material strip, and on the first middleware, stamp out multiple salient points;
C, by continuous mould to carrying out for the first time 90 degree bendings along the straight line between two described linking points of the horizontal the same side of material strip on the first middleware, the part that the first middleware both sides crimp bag is held together is mutually vertical with the middle part of the first middleware, form the second middleware, accordingly, the middle part of the second middleware g2 forms the isosceles trapezoid with minor face and long limit;
D, the 90 degree bending operations for the second time of the middle part of the second middleware being carried out longitudinally paralleling with material strip along the end of minor face, bending direction is contrary with 90 degree bending operations for the first time, form the 3rd middleware, the middle part of the 3rd middleware g3 has the straight trough g31 that the degree of depth progressively increases from a side direction opposite side, and both sides are connected with the flank g32 of inclination;
E, by the oblique impact aperture apparatus that is positioned at continuous mould, flank is carried out to oblique impact hole, form the 4th middleware g4, then cut off the 4th middleware and make the 4th middleware fall the described support frame of formation from material strip along the connecting band g41 of the longitudinal both sides of material strip and material strip.
Wherein, in order to ensure bending effect, described 90 degree bendings for the first time and for the second time 90 degree bending operations complete by twice bending respectively.
