Motion is carried out simultaneously；
4th, whole bending：After actuator 61 drives, when lifter cam part 64 rotates, horizontal drive wheel 65 also revolves simultaneously
Turn, after first time bending tool 35 and second time bending tool 37 are risen at the heel of lower stitch, the projection of horizontal drive wheel 65
652 contact with the 6th roller 682, and projection 652 first passes through the lower bending horizontal drive link member 681 of the 6th roller 682 driving and acted,
The lower bending horizontal drive link member 681 of action drives horizontal sliders 33 with second time bending tool by the 7th roller 683
37 are moved towards first time bending tool 35, and the lower stitch to have pre-bended is pressed to first time bending tool 35, lower pin by the first bending tool
Pin in the presence of the second inclined-plane 38 of the first inclined-plane 36 of the first bending tool and second time bending tool 37 bending to final folding
Bending angle；
5th, reset：The completion that pre-bends of lower stitch, upper bending mechanism 20 just the first roller 662, the second roller 663,
Origin-location is returned in the presence of first cam 642 of first connecting rod component 661, the 3rd roller 664 and lifter cam part 64, under
Bending mechanism 30 is then after lower stitch completes final bending, in the 4th roller 672, second connecting rod component 671, the 5th roller
673 and lifter cam part 64 the second cam 643 in the presence of return to origin-location, while second time bending tool 37 is in the 6th rolling
Wheel 682, lower bending horizontal drive link member 681, the 7th roller 683 and horizontal drive wheel 65 projection 652 in the presence of return
Origin-location；After upper bending mechanism 20, lower bending mechanism 30 and second time bending tool 37, which return, ships position, actuator 61
It is out of service.
When to carry out stitch bending next time, repeat the above steps.
Above-mentioned High speed cam bending mechanism, driven by feed mechanism 50 by the sheet feeding belt that needle plate forms in material strip runner
Moved on 50, realize the lower section that needle plate is automatically sent to upper bending mechanism 20 one by one, artificial filled needle plate relative to traditional
It is sandwiched on tool, improves bending efficiency, and lower stitch deformation caused by traditional tool multiple clamping can also be reduced, and it is gold-plated
Scratch, it ensure that the quality of lower stitch；Upper bending mechanism 20 is driven to pre-bend lower stitch by cam drive system 60,
And driving lower bending mechanism 30 to correct the lower stitch to pre-bend to specified bending angle, this aspect is realized automatically under
The bending of stitch, and bending twice causes lower stitch to be not susceptible to bending fracture, and bending essence is high, is less prone to waste product, separately
One side cam drive system 60, which can drive, can occur compact action replacement between bending mechanism 20 and lower bending mechanism 30
To complete the bending work to lower stitch, the lower stitch bending of high speed is realized, substantially increases bending efficiency.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
