At present, composite wood feed collet muscle wallboard forming, adopts clamp shelf structure on shaping mould, to locate long purlin mostly.For the multiple material wallboard with curvature, especially the Composite Panels of deep camber adopts long purlin, clamp shelf structure location, exist the increase of clamp manufacture difficulty, clamp distortion, multiple tracks clamp to cause the problems such as manufacturing cost increase, simultaneously, adopt long purlin, clamp shelf structure location, very high for vacuum bag technique requirement processed, otherwise in curing pressure process, very easily there is quick-fried bag phenomenon.
Summary of the invention
The present invention seeks to propose the method for curvature multiple material wallboard long purlin locate of a kind of solution with the long purlin of the multiple material wallboard of curvature orientation problem.
Technical solution of the present invention is:
The first step: frock is prepared, first, one block length purlin location-plate is respectively set at the upper surface two ends of covering forming frock, distance between two block length purlin location-plates is greater than the length of long purlin, then, the long purlin of preparation forming frock, long purlin forming frock is divided into two half modules, on each half module, be evenly distributed with locating hole, two half modules are located by locating hole;
Second step: utilize covering forming frock moulding covering, after covering forming completes, long purlin location-plate is installed in covering forming frock;
The 3rd step: according to designing requirement paving prepreg, after matched moulds,, vacuumize, pre-compacted by designing requirement paving prepreg on the base of long purlin shaping mould on the forming frock of long purlin;
The 4th step: the locating hole on the long purlin location-plate in locating hole and the covering forming frock at forming frock installation two ends, long purlin is located with alignment pin;
The 5th step: vacuum bag processed, the resin parameter curing molding using according to design.
When the length of described long purlin is not identical, the long purlin forming frock of two kinds of different lengths of preparation, the long purlin location-plate of one end of the short long purlin frock of length and covering forming frock one end is located, and the other end and adjacent long purlin forming frock are located.
The advantage that the present invention has and beneficial effect: the present invention adopts assembled tool structure, by locating the mode of long purlin forming frock, solution is the orientation problem in the forming process of long purlin with the multiple material wallboard of curvature, and the clamp of having avoided adopting traditional locate mode locate and occurring manufactures that difficulty, clamp are out of shape and the problem such as multiple tracks clamp location; Meanwhile, the present invention, by this kind of tool structure form, provides the localization method of the long purlin of staggered multiple material wallboard, the long purlin of a kind of length in forming process, has improved long purlin positioning precision, ensures long purlin Forming Quality.
