The adjustable feeding edge-folding mechanism of nip machine
The material phenomenon neither can take place when the present invention relates to a kind of flanging to run, and the adjustable feeding edge-folding mechanism of nip machine that has preform, flanging standard, flanging good forming effect again belongs to nip machine and makes the field.
The edge-folding mechanism of existing nip machine; Two inclined-planes of first guide pad are that the employee assembles, debugs with long-term accumulating experience on structural design; Final grinding hand-manipulated forms; The weak point of its existence is: the one, and not only all angle disunities, the gradient of wearing on the both direction is often led because of empiricism in big inclined-plane, causes the generation of running the material phenomenon; The 2nd, take a lot of work, time-consuming, the operative employee has often spent the time most of the day and can not assemble qualified product, has both made to assemble; Because guide pad is the spot welding location, cause the 3rd defective to produce like this, promptly dispatch from the factory after after the long-time use of client; Another inclined-plane of guide pad occurs and before roll the wheel wheel face, and after the distance increase, then can't turn its spacing down apart from increase; Thereby cause forming effect bad, or be difficult to be shaped.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, the material phenomenon neither can take place to run, the adjustable feeding edge-folding mechanism of nip machine that has preform, flanging standard, flanging good forming effect again when designing a kind of flanging.
Design: in order to realize above-mentioned purpose of design.The present invention on structural design, the one, on the basis of existing nip machine edge-folding mechanism, changed the function of guide pad; The end face of guide pad has only the gradient (on the figure X angular range in) of a direction, and making its function letter two is one, only play the effect that holds up labor and materials; The purpose of doing like this is: the gradient workpiece of a direction; Not only be convenient to processing, also assembling easily also can not be run material when elbow is worked; The 2nd, increased the gib block that can debug, this gib block plays the preform effect, the preform workpiece; What lean on is the preform angle (the Y angular range is interior on the figure) of circular arc place band gradient, and the purpose of doing like this is: easy for installation, as long as good figure is gone up zero line place size; And when the client uses this elbow for a long time, because when rolling wheel wheel face and gib block arcwall face before for a long time wearing and tearing cause and can't pressure rolling going out the bent angle of standard apart from increase, this moment is as long as become flexible adjustment screw; Roll wheel direction trace mobile guide piece forward; Can turn distance down, mix up back lock-screw (ordinary circumstance debugging one to secondary promptly can), but just pressure rolling go out satisfied bent angle.
Technical scheme: the adjustable feeding edge-folding mechanism of a kind of folding brake, it comprises the feeding edge-folding mechanism, the guide pad spigot surface in the said feeding mechanism is the inclined-plane, and under guiding surface, to have the concave station table top be that plane, concave station platform wall are the crescent concave station of arc; Roll wheel before said by preceding rolling wheel wheel face and the front jocket wheel wheel face constitutes and the preceding diameter that rolls the wheel face diameter greater than leading wheel face; Roll after said wheel by after roll that the wheel wheel face constitutes with back guide wheel wheel face and after roll the wheel face diameter less than back guide wheel face diameter, preceding roll in the wheel before roll wheel wheel face and front jocket wheel wheel face with after roll in the wheel after roll the wheel wheel face with after guide wheel wheel face relative engagement; The gib block front end present arc head under the breach and down arc head extrados lower sideline match and leave with arc concave station platform wall in the guide pad and prevent dry and astringent gap.
The present invention compares with background technology, and the one, the race material that has solved the background technology existence reaches the phenomenon that is difficult to the flanging moulding after long-term the use; The 2nd, assembling is simple, convenient; The 3rd, the bent angle standard of institute's pressure rolling, reliable in quality.

The specific embodiment
Embodiment 1: with reference to accompanying drawing 1-9.The adjustable feeding edge-folding mechanism of a kind of nip machine, it comprises the feeding edge-folding mechanism, guide pad 3 spigot surfaces 303 in the said feeding mechanism are the inclined-plane, and under guiding surface, have concave station table top 301 and be the crescent concave station of arc for plane, concave station platform wall 302; Wheel wheel face 201 constitutes with front jocket wheel wheel face 202 and the preceding diameter that rolls wheel wheel face diameter greater than the front jocket wheel wheel face by preceding rolling to roll wheel 2 before said; Roll after said wheel 1 by after roll that wheel wheel face 101 constitutes with back guide wheel wheel face 102 and after roll wheel wheel face diameter less than back guide wheel wheel face diameter, preceding roll in the wheel 3 before roll wheel wheel face 201 and front jocket wheel wheel face 202 with after roll in the wheel 1 after roll wheel wheel face 101 and back guide wheel wheel face 102 relative engagement; Gib block 4 front ends present 401 times arc heads 402 of breach and down arc head 402 extrados lower sidelines match with arc concave station platform wall 302 in the guide pad 3.Be positioned at following arc head 402 arcwall faces of gib block 4 leading sections with before roll wheel 2 201 before to roll the spacing of wheel wheel face adjustable.The bar of said gib block 4 has horizontal bar shaped adjustment hole 404 on one's body.Said gib block 4 with roll wheel plate 6 and be connected and roll wheel plate 6 and be fixed on the base plate 9, gib block 4 and make gib block 4 front and back vertically move the location through horizontal bar hole 404 in the gib block 4 and the adjustment screw 5 that is positioned at lateral adjustments hole 404.Said base plate 9 is provided with manually seaming forming tank 8 in advance.
What need understand is: though the above-mentioned instance text description detailed to contrasting of mentality of designing of the present invention; But these text descriptions; Just the simple text of mentality of designing of the present invention is described; Rather than to the restriction of mentality of designing of the present invention, any combination, increase or modification that does not exceed mentality of designing of the present invention all falls in protection scope of the present invention.
