Abstract
The invention relates to a trail-produced interior trim part forming technology, belonging to the field of automobile technological design. The technology includes the following steps: blanking, binding, numerical control inner chamber processing, inner chamber filling, numerical control profile processing, profile milling, polishing, leather cladding, strickling and cutting. By adopting a quick forming mode, the production period of parts is greatly shortened, and can be shortened by 75 percent, namely, 90 days; cost for trail-producing dies is saved by about 3 million yuan, dimension precision of products is ensured, solid foundation is laid for product forming, and the practicability is strong. 'Quickness' and 'high dimension precision' cause trail-production to quickly provide theoretical data for formal production. The phenomenon that the product can not be well verified before being put into production is avoided, and the investment risk for product production is reduced.
Description
Technical field
The present invention relates to the automobile technology design field, particularly a kind of interior trimming parts forming process of manufacturing experimently production.
Background technology
Interior trimming parts mainly refers to be installed on the parts such as instrument carrier panel, seat, bearing circle, ceiling, handrail, door inner panel, baggage container liner and engine bonnet liner in the automobile.In recent years, along with the development of Automobile Design and Manufacturing technology, the requirement of to interior is also more and more higher.
At present, because the product renewal of automobile is more and more faster, more and more to special vehicle trial-production demand, both required quality, require again progress, and the to interior build guality require more and more higher, not only require automotive upholstery shape, material and matching in color, satisfy functional requirement, more require attractive in appearance, the comfortable and cost of interior trimming parts etc. simultaneously.
At present, great majority all are to adopt the mode of design, processing mold to finish interior trimming parts trial-production, this mode easily causes trial-produce period length, accessory size not exclusively to satisfy the design paper requirement, can not seize the risk in market the very first time, but also can not satisfy the actual demand of project.
Summary of the invention
The object of the present invention is to provide a kind of interior trimming parts forming process of manufacturing experimently production, solved and adopted mould to finish that the trial-produce period that interior trimming parts trial-production exists is long, accessory size not exclusively satisfies the risk that design paper requires, can not seize market the very first time, but also can not satisfy the problem such as project.The present invention adopts non-metallic material (ABS sheet material) to adopt the numerical control machining mode to finish forming parts, adopt method of heating to make itself and forming part bonding with the PVC material, finish the manufacturing of interior trimming parts, can reach that accessory size is accurate, the process-cycle is short and the purpose of good looking appearance.
The technical scheme that technical solution problem of the present invention adopts is:
The interior trimming parts forming process that trial-production is produced comprises the steps:
One, blanking
Adopt nonmetal plate, use CATIA according to part shape and big or small blanking;
Described nonmetal plate can be for the ABS plate, can process resin, organism glass etc.
Two, sizing
By blanking figure size sizing;
Three, numerical control machining inner chamber
Adopt the numerical control machining mode to process inside face with ball head knife;
Four, inner cavity filled
The inner chamber of the thin arm bowl type spare that the employing gypsum material will machine tamps, and packing volume accounts for 93% ~ 97% of mold cavity volume; If plate part need not to fill with gypsum;
Five, numerical control machining profile
Adopt the numerical control machining mode to process profile with ball head knife;
Six, mill profile
In the situation that inside and outside surface all machines, machining profile removes binder surface, finishes numerical control machining;
Seven, sanding and polishing
Go tool marks with coarse grain sand paper 400 orders first, remove cut with 800 order sand paper again, polish with 1000 order sand paper at last;
Eight, coat leather
On the product outside face, be 0.1 ~ 0.25mm with glue thickness with the glue brushing, leather caught up with to another side from part that fine coating is avoided bubbling on one side;
Described coating leather glue is 841 neoprenes, high performance structures AB glue, acrylate glue etc.
Nine, strike off
To bubble or unfairness place strikes off with cardboard or plank;
Ten, blank
Remove excess stock, guarantee that product is attractive in appearance, be finished product.
Beneficial effect of the present invention is:
" soon " reaches " dimensional accuracy is high ", trial-production produced can provide gross data to putting into serial production fast.The phenomenon of having avoided product can not finely be verified before operation has reduced the investment risk that product is gone into operation.By the rapid shaping mode, greatly shortened the manufacturing cycle of part, can reach and shorten namely 90 days manufacturing cycle 75%; Saved the cost of trial-production production mould, can save approximately 3,000,000 yuan of die cost, and the dimensional accuracy of product is guaranteed, and for the typing of product lays a solid foundation, practical.
