Abstract
The invention discloses a molding process for a ceiling of a complex shape. The molding process is characterized by comprising the following process steps: a, process data processing: rotating a molded surface according to ceiling deformation, and correlating the rotation degree with a shape and a state; b, material compounding: compounding a plurality of ceiling materials together, and arranging reinforcing bands on both sides of a ceiling material; c, molding: molding the ceiling material into a real object via a die; d, cutting: cutting off slitter edges, abandoned holes and the like of the molded real object; and e, trimming: removing burrs, surface foreign matters, dirt and the like. According to the molding process, a shape which can only be realized with the conventional two-step wet process is realized by adopting a one-step dry method process, so that the requirement of product definition can be met, the requirement of industrial production can be met, the product cost is lowered, and the cost performance of a product is increased.
Description
Technical field:
The present invention relates to the ceiling field shaping technique, is a kind of forming process of ceiling specifically, is specially adapted to the moulding of complex model ceiling.
Background technology:
At present, the ceiling moulding generally adopts wet processing, dry process moulding according to profile, and the gap between two kinds of technique is larger.Existing traditional dry process, a) process data process, b) Material cladding, c) moulding, d) cutting, e) the finishing technique step, described a) process data treatment step profile adjustment process need guarantee the drafting angle (existing analytic product draft angle only has 10 °, does not directly use this technique in the past) of minimum 15 ° of product; Described b) the Material cladding step is combined with each other multiple material, does not generally increase stiffening band; Described c) forming step is in kind by the ceiling material by mould molding; Described d) cutting step cuts away the slitter edge in kind of moulding, useless hole etc.; Described e) arranging step disposes burr, Superficial Foreign Body, dirty etc.Traditional dry process can be realized the moulding of complex model ceiling, but local complex model position can not meet the definition requirement, and difference is larger, and rigidity is poor.
Wet processing, a) process data process, b) material consolidation, c) moulding, d) compound, e) cutting, f) the finishing technique step, described a) process data treatment step profile need not be processed substantially, by former granting data, is undertaken; Described b) the material consolidation step is prepared the material of different layers, put in order; Described c) forming step is in kind by ceiling skeleton (except precoat) by mould molding; Described d) composite steps is combined with each other fabric and skeleton; Described e) cutting step cuts away the slitter edge in kind of moulding, useless hole etc.; Described f) arranging step disposes burr, Superficial Foreign Body, dirty etc.Two step wet processings can be realized complex model, and meet the definition requirement, but relevant tooling cost is too high, and motor plant can not be accepted.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of forming process of complex model ceiling is provided, mainly solve existing product deflection and stiff problem.
Technical scheme of the present invention is: a kind of forming process of complex model ceiling, and its special character is to comprise following processing step:
The a process data is processed: according to the ceiling deflection, profile is rotated, the rotation number of degrees and moulding, state are relevant;
B Material cladding: by multiple ceiling Material cladding together, and increase stiffening band in ceiling material both sides;
C moulding: be in kind by mould molding by the ceiling material;
D cutting: the slitter edge in kind of moulding, useless hole etc. is cut away;
E arranges: burr, Superficial Foreign Body, dirty etc. are disposed.
Further, the described profile rotation of a step number of degrees are 10 °.
Compared with the prior art the forming process of a kind of complex model ceiling of the present invention has outstanding substantive distinguishing features and marked improvement: in process data processing and material consolidation step, improved, break through ceiling industry wet processing, dry process excellent, the shortcoming between separately in the past, make the gap between its two kinds of techniques more and more less, identical profile all can realize on dry, wet processing, solved bound to moulding of technique in industry, reduce cost of product, improve the product cost performance.
The specific embodiment:
For Comprehension and Implementation better, below provide specific embodiment and describe the present invention in detail; Illustrated embodiment is only for explaining the present invention, not for limiting the scope of the invention.
Embodiment 1, according to the ceiling deflection, by profile rotation 10 degree, by these data, carries out mould development, after meeting moulding, distortion, still meets the definition requirement; According to checking, by multiple ceiling Material cladding together, and increase stiffening band in ceiling material both sides, to reduce the deformation of products amount, make its angle, rigidity meet the definition requirement; Then by the ceiling material, by mould molding, be in kind; Again the slitter edge in kind of moulding, useless hole etc. is cut away; Finally by burr, Superficial Foreign Body, dirty etc. disposing; Complete the forming process of complex model ceiling.
The forming process of a kind of complex model ceiling of the present invention, in process data processing and material consolidation step, improved, break through ceiling industry wet processing, dry process excellent, the shortcoming between separately in the past, make the gap between its two kinds of techniques more and more less, identical profile all can realize on dry, wet processing, solved bound to moulding of technique in industry.
Claims (2)
