The present invention preferably relates to a kind of equipment that is used for the edge flanging of first housing parts, described first housing parts are preferably formed the outside of body, wherein the edge of second housing parts (for example, forming the inside of body) is arranged in the flanging groove of first housing parts.This equipment comprises the crimping head of have at least one anti-roll (counter pressure roller) and preferred at least two pressure rollers, be used for continuous edge upset with first housing parts, described anti-roll is bearing in the outside of first housing parts, and pressure roller is relative with anti-roll or each pressure roller is relative with an anti-roll.
Background technology
For example said circumstances occurs in the situation of the wheel arch of car body, wherein the outer part of body must be connected with interior part by flanging.The shell of body has the cross section of circular arc (being preferably semicircle), and so-called wheel arch is anchored on the inboard of body on the edge in this cross section.The problem here is that the outside of shell should not be out of shape or distortion at least as few as possible, promptly, for example necessarily any depression or scratch can not be for example produced,, and the aesthetic effect that car body is intended to show will be destroyed because these will be immediately as seen when shell is painted afterwards.
In principle, because anti-roll will and make its distortion along the movement outside of shell, so ban use of the flanging equipment that comprises pressure roller and anti-roll.So far the sliding part that the solution known to is radially outward moved with respect to the wheel part at the shell edge rear by use, thus its inside upset is realized.Because omitted counter-pressure here, so flanging quality and not always satisfactory.In addition, this has related to the device that only is exclusively used in a kind of vehicle body in each case relatively, and this makes and to use this device to have problem in the production facility generate dissimilar bodies therein.
Summary of the invention
The objective of the invention is to utilize simple device will be preferably car body or install after the edge of parts (especially outer metallic plate) of body part overturn so that these parts do not deform.This equipment also should so constitute so that it can promptly adapt to different component shape.
The present invention relates to a kind of crimping equipment, it comprises crimping head, at least one first crimping roller and at least one second crimping roller, and each of these crimping rollers all pivots by the crimping head.Under the situation of roll extrusion crimping, the first crimping roller has formed pressure roller, and it is at the edge for the treatment of crimping, and the narrow rim strip (rim strip) that is preferably parts is gone up roll extrusion.The second crimping roller is with acting on the anti-roll of first volume limit roller, that is, for rim strip with for example 30 ° or 45 ° of crimpings, this anti-roll bears the power that is applied by the first crimping roller.According to their function separately, below the first crimping roller is called pressure roller, and the second crimping roller is called anti-roll.Especially, the crimping head can be fastened on the end of manipulator, and this manipulator preferably has whole six degrees of freedom of motion, but has the required free degree of crimping processing self at least.
According to the present invention, this crimping equipment also comprises stable protection structure, and this protection structure can be fastened on the parts or be fastened during the roll extrusion crimping.For anti-roll, this protection structure or self form rolling surface, and anti-roll roll extrusion on this rolling surface during the roll extrusion crimping perhaps only forms rolling surface by the rolling surface of the direct roll extrusion thereon of supporting anti-roll indirectly.Under first kind of situation, the inboard of protection structure abuts against parts and is preferably shaped to its surface and matches.The outside of protection structure is formed for the rolling surface of anti-roll.Under second kind of situation, the protection structure is arranged in the interior zone of curled edges to be formed, and abuts against the inboard of parts, wherein protects structure optimization to be configured as with inner surface and matches.Because parts are supported in the inboard, so it can self be formed for the rolling surface of anti-roll under second kind of situation, however, it can not be out of shape owing to pushing anti-roll, and perhaps comparing than the situation that does not have supporting in the inboard has very little distortion.
If protection structure self forms rolling surface; not directly roll extrusion on parts of anti-roll so; but roll extrusion on the protection structure; this protection structure optimization has formed a kind of matrix that matches with the inboard parts outline, thereby even the space structure of parts minimum also can accurately duplicate and needn't fear distortion.Crimping head self can be a type, and it also can be used for other crimping processing.In sum, this has such advantage, that is, many different bodies can be processed on the production line that for example is used for car body (being preferably car body).Only need to keep the protection structure that matches respectively, these protection structures can begin at first that the crimping first being processed is placed on the body or insert in the interior zone of curled edges.
In a preferred embodiment, the drape forming that protection structure and zone to be protected lean for described parts consistent against the zone, thereby make protect structure and parts front (full-face) against.
