Further, the set-up mode of above-mentioned a pair of of mounting portion has the following two kinds embodiment, two different implementations
Mode determines the sheared edge J for being capable of forming two kinds of different function:
One, the first embodiment: upper mounting portion 201a and lower mounting portion 201b is symmetrical arranged, and the two is just mutual
Face.It is identical with 300 structure of cutter unit in lower slot 201b-1 due to being set to upper slot 201a-1, two cuttings
The cutter head 301 of unit 300 just can be faced mutually.Indent is respectively formed at the cutter head 301 of present embodiment two faces of setting
The edge of a knife (edge of a knife can for V-arrangement, semicircle, half elliptic etc.), then two edges of a knife can be faced mutually, and the common folder that encloses is forced into
Sheared edge J.Two cutter units 300 in the embodiment are due to mutually facing, when 301 arm of angle of cutter head of the two is mutual
It is the smallest wire stripping size when contact, the zoom ranges of sheared edge J are limited, cannot continue to zoom out.
Two, second of embodiment: upper mounting portion 201a and lower mounting portion 201b form the dislocation in axial direction, and the two cannot
Just face.In this embodiment, the two sides for setting cutter unit 300 are respectively the first face 303 and the second face 304, together
Sample, it is identical with 300 structure of cutter unit in lower slot 201b-1 to be set to slot 201a-1, two cutter heads 301 in
Spill is at the edge of a knife, and two edges of a knife enclose sheared edge J jointly.Enable: the first face 303 of two cutter units 300 mutually fits
(the second face 304 away from each other, forms respective lateral surface), and can both occur to slide relatively, therefore, by opposite
Sliding can expand or reduce sheared edge J, and the plane where the first face 303 mutually to fit is shear surface.Preferably, knife
The V-arrangement edge of a knife of indent is respectively formed at first 301.Sheared edge J in the embodiment can carry out a degree of big minor adjustment, and
And it can be replaced plus cutter unit 300 itself with withdrawing different specifications (such as opening angle of the V-arrangement edge of a knife), therefore sheared edge J
Zoom ranges it is more selective.
Cutter unit 300 among the above can carry out opposite sliding in upper slot 201a-1 and lower slot 201b-1, with
Change the size of sheared edge J, the embodiment for sliding control is as follows:
The punck-down block further includes adjusting unit 500, for squeezing the knife tail 302 of cutter unit 300, adjusts sheared edge
The opening dimension of J.It is specific:
Adjusting unit 500 includes the first linkage section 501 and the second linkage section 502 to overlap, 501 He of the first linkage section
Second linkage section 502 is axially along the tubular structure stretched and overlapped, and the outer end of the first linkage section 501 is additionally provided with horn mouth
503, adjust the preferred integral structure of unit 500.Horn mouth 503 is the horn-like structure dehisced outward, and medial surface is slope surface.
There is internal screw thread 501a, on 203 lateral wall of joining section of rotating unit 200 on the inner sidewall of first linkage section 501
With the external screw thread 203a cooperated with internal screw thread 501a, the first linkage section 501 passes through internal screw thread 501a's and external screw thread 203a
The connection with joining section 203 is realized in cooperation.
Second linkage section 502 is placed on the periphery of fixing end 101, and can be axial with the whole generation together of unit 500 is adjusted
Opposite sliding.Specifically, being provided with the first longitudinal conducting bar 502a (axial bar shaped on the inner sidewall of the second linkage section 502
Structure), there is on the lateral wall of fixing end 101 guide groove 101a, the first conducting bar 502a insertion for being matched with the first conducting bar 502a to lead
It in slot 101a, and can slide axially, so that adjusting, unit 500 is whole can to occur axial opposite sliding.By
It is fixed relative to rotating unit 200 in feed unit 100 namely fixing end 101 is relatively fixed motionless, therefore, work as driving
When unit 400 drives rotating unit 200 to be rotated, internal screw thread 501a and the cooperation of external screw thread 203a and the limit of guide groove 101a
Fixed so that adjusting unit 500 to be merely able to that axial straight-line displacement occurs, finally, the inner sidewall of horn mouth 503 can be right in displacement
The inside of knife tail 302 is squeezed, and the slid inward in upper slot 201a-1 and lower slot 201b-1 of cutter unit 300 is pushed,
Realize the diminution of sheared edge J.Preferably, the inner end of guide groove 101a blocks, outer end is penetrating.
In addition, the two sides upper slot 201a-1 of upper mounting portion 201a are symmetrically arranged with accommodation groove 201a-2 in communication,
And the two sides of cutter unit 300 are provided with the second conducting bar 305 corresponding to accommodation groove 201a-2, the insertion accommodating of the second conducting bar 305
In slot 201a-2, and opposite inside and outside sliding can occur.
The bottom of accommodation groove 201a-2 has rest block 201a-3, is fixed with elastic component 201a-4 on rest block 201a-3,
Elastic component 201a-4 uses compressed spring, between rest block 201a-3 and the second conducting bar 305, therefore it is single with that will cut
The trend that member 300 ejects outward.Therefore, in conclusion passing through the comprehensively control of elastic component 201a-4 and horn mouth 503, energy
Enough glide direction or stable in required commitment positions of the control cutter unit 300 in upper slot 201a-1.In the present invention
In, since the structure of lower mounting portion 201b is identical as upper mounting portion 201a, cutter unit 300 leads in lower slot 201b-1
The mode that overcompression spring carries out installation connection is identical as upper slot 201a-1, does not repeat herein.
Preferably, for second of embodiment in " set-up mode of mounting portion " among the above, the of cutter unit 300
Correspond to the compensation convex block 306 that evagination is provided at one end of knife tail 302 on 303 on one side.Due to upper mounting portion 201a and lower peace
Dress portion 201b forms the dislocation in axial direction, so that upper and lower two cutter units 300 also form dislocation (only by first face of the two
303 fitting contacts), therefore, compensation convex block 306 can guarantee that the knife tail 302 of two cutter units 300 can be with horn mouth
503 inner sidewall contact, realizes the synchronously control to two cutter units 300.
Further, the punck-down block further includes shedding unit 600, can to rotational shear go out line skin end into
The work that row is extracted and fallen off.
Specifically, shedding unit 600 includes the shedding casing 601 of face sheared edge J.601 main body of shedding casing is casing
Shape structure, one end inwardly, and with sheared edge J face, the other end outwardly, for as cut line skin the outlet that falls off.It is preferred that
, the inner end of shedding casing 601 forms the horn-like of opening, which is conducive to the insertion of harness end.
The outer end face that the periphery of shedding casing 601 passes through circumferentially uniformly distributed multiple connecting brackets 602 and the fixing end 101
Connection, one end of every connecting bracket 602 and the lateral wall of shedding casing 601 are fixed, the outer end face of the other end and fixing end 101
It is fixed, therefore can guarantee that shedding unit 600 and feed unit 100 can be fixed relative to rotating unit 200.Compared with
Good, actuator 401 can also be fixed between adjacent connecting bracket 602.
The internal arrangement of shedding casing 601 has the overhead kick 601a of direction outwardly.Preferably, overhead kick 601a is along shedding casing
The uniformly distributed circle of the circumferential direction of 601 inner sidewalls, forms an overhead kick group D, and shedding casing 601 is arranged in the axial direction with multiple groups overhead kick group D.
When actually using punck-down block, harness is inserted into feeding-passage 103, the end of harness, which is taken advantage of a situation, is able to enter face
Shedding casing 601 in.Since the direction of overhead kick 601a and the direction of insertion of harness are identical, harness can smoothly enter into and move back
In leather sheath pipe 601.When one section of line skin of harness end is had no progeny by rotary cutting, if extracting harness, due to extracting direction and overhead kick
601a's is contrary, therefore the line skin cut can be trapped in shedding casing 601, and wire harness main body can extract out,
The extraction of line skin is realized with this.
In the insertion and shearing operation of next round harness, the new harness of insertion can be trapped in shedding for last round of
Line skin in casing 601 ejects shedding casing 601, realizes falling off for line skin.
From the above: the effect by adjusting unit 500, cutter unit 300 can also while being rotated
Radial motion, the final process for realizing rotational shear enough occurs.Since cutter unit 300 is not that straight line is opposite to the cutting of line skin
Extrusion shearing, but by means of the rotational shear of rotating unit 200, therefore can clip to one week of line skin, be more advantageous to
Line skin is cut off comprehensively.Meanwhile cutting can more easily be controlled by the transmission ratio between driving member 402 and outer gear ring 202
The radial motion stroke of unit 300 and the movement range of cutter head 301, are conducive to the depth of cut for being precisely controlled cutter head 301, keep away
The problem of exempting from existing easy cutting damage during the opposite extrusion shearing of traditional straight line to core.
Further, since the cutter unit 300 in the present invention is inserted directly on the mounting portion for being mounted on intermediate plate ring 201, therefore
Convenient for blade replacement, renew.
It should be noted that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to preferable
Embodiment describes the invention in detail, those skilled in the art should understand that, it can be to technology of the invention
Scheme is modified or replaced equivalently, and without departing from the spirit and scope of the technical solution of the present invention, should all be covered in this hair
In bright scope of the claims.
