Adopt the technical solution of the utility model, there is following technique effect:
The compressing technique adopting top die to coordinate with lower bed die, shapes to lead-in wire; Wherein said lower bed die is provided with support column, support column upper end is provided with guide wheel, the sidewall of described top die is at least provided with two compacting wheels, and compacting wheel mutually stagger with support column (namely above-mentioned adjacent suppress take turns between be between upper nip, for pressing down interval between adjacent supports post, described support column is in immediately below between described upper nip, presses down directly over interval described in described compacting wheel is in).
During use, by lead placement between top die and lower bed die, no matter be that top die is descending, still lower bed die is up, as long as gap smaller between top die and lower bed die, described guide wheel is taken turns with compacting and just can be suppressed described lead-in wire, and the wheel face of taking turns due to guide wheel and compacting is comparatively level and smooth, the contact surface of bending part also comparatively large (compared with single-point bending of the prior art), can avoid stress to concentrate caused core impaired.
Further, described in press down interval and be provided with to be arranged on lower bed die vertically wears pin, described vertically wearing between pin and lower bed die is provided with back-moving spring.
Described vertically wear pin play to compacting wheel carry out descending spacing effect, avoid compacting wheel excessively descending.
If vertically wearing pin is be fixed on lower bed die, then suppresses wheel and directly and vertically can wear pin rigid collision, affect the mechanical stability of whole lead-in wire not damaged bending tool, but also the lead-in wire being in compacting wheel and vertically wearing between pin can be damaged.For this reason, back-moving spring is set vertically wearing between pin and lower bed die, make compacting wheel can with vertically wear pin Elastic Contact (contact stress becomes large gradually with deformation, instead of collision property ground increases suddenly), be conducive to protection lead-in wire.
Further, the sidewall of described top die is provided with four compacting wheel, described lower bed die is provided with altogether three support columns and two vertically wear pin.
If only arrange three compacting wheels, support column corresponding to that position just only has two, only has one section of lead-in wire to be pressed down distortion between two support columns, can not ensure that lead-in wire no longer resets like this.If after four compacting wheels, three support columns and two vertically wear pin, according to aforementioned position relationship, can form the lower compressive strain of two sections, by contrast, lead-in wire more not easily resets.
Further, described lower bed die is provided with the installing hole vertically wearing pin for installing location, and described back-moving spring is located in installing hole, and the upper end of described lower end and back-moving spring of vertically wearing pin offsets.
Being positioned vertically wearing pin by installing hole, and additionally increasing compared with positioning seat, improve herein and be more conducive to saving cost of manufacture.
