The manufacturing process of fiber glass reinforced plastics bracket for water cutting of automobile interior ornaments
Technical field
The present invention relates to a kind of manufacturing process of water glass-cutting steel bracket, particularly the manufacturing process manufacturing process of a kind of low cost of manufacture, fiber glass reinforced plastics bracket for water cutting of automobile interior ornaments that efficiency is high.
Background technology
In auto manufacturing, how automotive upholstery is by water excision forming, and during cutting, automotive upholstery is placed on water glass-cutting steel bracket, high pressure cutting water on glass fibre reinforced plastic bracket, is provided with the water cutter cutting groove corresponding with water cutter cutting track, so that can complete cutting through inside gadget smoothly.Traditional automotive upholstery water glass-cutting steel bracket during fabrication, first by polyurethane material, process the model with water glass-cutting steel bracket profile, utilize this model to carry out pasting of glass fibre reinforced plastic bracket, finally glass fibre reinforced plastic bracket is delivered to machining center and process, mill out the water cutter cutting groove in bracket profile.Adopt the glass fibre reinforced plastic bracket manufacturing cost producing in this way high, the process-cycle is long.
Summary of the invention
The technical problem to be solved in the present invention is to provide the manufacturing process manufacturing process of a kind of low cost of manufacture, fiber glass reinforced plastics bracket for water cutting of automobile interior ornaments that efficiency is high.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of manufacturing process of fiber glass reinforced plastics bracket for water cutting of automobile interior ornaments, and its innovative point is that described step is: first by polyurethane material, process the model with water glass-cutting steel bracket profile; Then in the profile of this model, along water cutter cutting groove track, paste adhesive tape; Finally utilize the model that is pasted with adhesive tape to carry out pasting of glass fibre reinforced plastic bracket.
The invention has the advantages that: by the strong adhesive tape of pasting plastic when the model manufacturing, make model when carrying out the pasting of glass fibre reinforced plastic bracket, glass fibre reinforced plastic bracket surface directly can form water cutter cutting groove, without the machining of carrying out again water cutter cutting groove after completing in glass fibre reinforced plastic bracket manufacture, production cost and manufacturing cycle have been reduced.
The specific embodiment
The present invention designs the manufacturing process manufacturing process of a kind of low cost of manufacture, fiber glass reinforced plastics bracket for water cutting of automobile interior ornaments that efficiency is high:
First by polyurethane material, process the model with water glass-cutting steel bracket profile, specific practice is to buy an overall polyurethane foamed blocks, then with machining center milling, be finish-machined to the model that pastes glass fibre reinforced plastic bracket profile needing, after fine finishining completes, the work in-process heart utilizes sharp knife along water cutting track, to carve an outline line in the profile of model.
Then in the profile of this model, along water cutter cutting groove track, be that water cutting track is pasted adhesive tape.
Finally utilize the model that is pasted with adhesive tape to carry out pasting of glass fibre reinforced plastic bracket, the concrete operation that pastes is: first go up demoulding paraffin, all profiles to model and adhesive tape surface are all coated with the uniform paraffin of last layer, to can smoothly the water cutting glass fibre reinforced plastic bracket body and model that paste be separated after having pasted; Be coated with gel coat, on paraffin layer surface, be coated with last layer gel coat, its effect is to prevent that glass-fiber-fabric is exposed at bracket surface.Carry out pasting of fiberglass, successively glass-fiber-fabric is layered on to model surface equably, then with hairbrush, be stained with the fiberglass liquid modulating and be repeatedly coated in equably on glass-fiber-fabric.After every layer of glass-fiber-fabric coating is complete, all to wait for all solidifying and just can carry out the coating of lower one deck afterwards.
