The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, a kind of embodiment of the present utility model is described in further detail.
A kind of band steel torsion module of the present embodiment, as in Figure 2-4, it comprises base 1, bearing 1, bearing 23 and spill spin block 4, wherein bearing 1, bearing 23 are fixedly installed on the upper surface of base 1 and bearing 1, bearing 23 is oppositely arranged, and spill spin block 4 is between bearing 1 and bearing 23, spill spin block 4 is connected with bearing one 2 rotary moveables, also comprises rotating driving device, for driving spill spin block 4 with respect to bearing one 2 rotations.Under original state, the upper surface 41 of spill spin block 4 is parallel with the upper surface of base 1, and the front surface 42 of spill spin block 4 is vertical with upper surface 41.And on spill spin block 4, be provided with the slot 1 matching with band steel, on bearing 23, be also provided with the slot 2 51 matching with band steel accordingly, above-mentioned slot 1 and slot 2 51 opposing parallel settings.For the aspect that is installed, slot 2 51 is comprised of container cavity 32 and voussoir 31, and container cavity 32 is arranged on bearing 23, and voussoir 31 is arranged in container cavity 32, and a madial wall of a sidewall of voussoir 31 and container cavity 32 forms slot 2 51; In order to provide band steel to reverse required space, 23 of spill spin block 4 and bearings are separated with the distance of holding band steel length.
Preferably, the bearing 36 that rotating driving device comprises patrix 7, be oppositely arranged with the front surface 42 of spill spin block 4 on base 1, forms the die cavity 9 that holds patrix 7 between bearing 36 and spill spin block 4; Under original state, the medial surface 62 that bearing 36 is relative with spill spin block 4 is parallel with the front surface 42 of spill spin block 4, and the distance between medial surface 62 and front surface 42 is less than the width a of patrix 7, therefore when patrix 7 undershoot, can contact with spill spin block 4, thus the power that provides spill spin block 4 to rotate relative to bearing 1; And when spill spin block 4 rotations 90 oafter, as shown in Figure 6, its upper surface 41 is parallel with medial surface 62, and upper surface 41 equates with the width a of patrix 7 with the distance between medial surface 62, so guarantees that spill spin block 4 just in time turns over 90 o, and make patrix 7 enter into die cavity 9, utilize the structure of mould itself to guarantee the precision that band steel reverses.
Due to patrix 7 undershoots, contact with spill spin block 4 in the process that makes spill spin block 4 rotations, its resistance is larger, therefore as shown in Figure 5, between the upper surface 41 of spill spin block 4 and front surface 42, by arc surface transition, contact, with this, reduce the resistance in patrix undershoot process, make the active force between patrix 7 and spill spin block 4 more steady.The resistance in this process that reduces for large as far as possible, is also provided with roller 71 at the arc surface place of patrix 7, and patrix 7 contacts with the arc surface transition of spill spin block 4 by roller 71.
Because the active force between patrix 7 and spill spin block 4 is larger, in order to prevent bearing 36 distortion, a side contrary with medial surface 62 on bearing 36 is also fixedly installed floor 61.
In the present embodiment, adopt the procedure of processing step of above-mentioned band steel torsion module twisted flat bar as follows:
A. described band steel torsion module is arranged on forcing press;
B. one end of band steel to be processed is inserted in the slot 1 on spill spin block 4, its other end inserts in the slot 2 51 of described bearing 23;
C. rotating driving device drives spill spin block 4 to rotate relative to bearing 23.
Wherein, in step C, above-mentioned rotating driving device drives spill spin block 4 to rotate 90 relative to bearing 23 o
Further, the upper surface 41 that the rotation of spill spin block is impacted spill spin block 4 downwards by described patrix 7 is realized.
After above-mentioned steps C completes, on patrix 7, exercise the upper surface that described patrix departs from described spill spin block.
The angle steel torsion module of the present embodiment, under original state, the distance between bearing 36 and spill spin block 4 is less than the width a of patrix 7, when patrix 7 drives spill spin block 4, turns over 90 oafter, the distance between bearing 36 and spill spin block 4 just in time equals the width a of patrix 7, and therefore, spill spin block 4 is guaranteed by mould structure itself with respect to the angle of bearing 23 rotations, so the mould structure of the present embodiment is simple, reverses precision high.Accordingly, because it adopts mechanical cold worked mode, avoided destroying because heating the material that inequality causes, reduced workman's labour intensity simultaneously, improved working (machining) efficiency.
In a word, be more than preferred forms of the present utility model, it should be pointed out that the improvement of making for those skilled in the art in the situation that not departing from the utility model substantive distinguishing features, be all considered as protection domain of the present utility model.
