A kind of automobile sash production technology
Technical field
The present invention relates to automotive fields, and in particular to a kind of automobile sash production technology.
Background technique
Currently, still belonging to blank for the technology country of aluminium alloy car door and window frame forming.Foreign countries, for section material section shape
Shape is more complex, is again the aluminium alloy car door and window frame of complex space geometry generally uses large complicated numerical-control bending machine
Make its forming.By taking 100 car front door upper window frame of Audi as an example, which is aluminium alloy, and section is hollow asymmetric
Section, shape are that there are six the rates of curving in four freedom degrees, are the complex space geometries of a Bending Deformation and distortion,
West Germany then uses large-sized numerical control Multi-direction Bending machine to be equipped with a variety of auxiliary machinery, auxiliary tool to produce, and the device is complicated expends largely
Fund.Such as a kind of forming process for automotive door and window frame section that China Patent No. is CN89108444.4, automobile door and window frames are broken
Face Shape decomposition is at several section configuration, if process arterial highway manufacturing procedure, every procedure process a kind of section configuration, finally
The processing of section configuration required for one procedure is completed, section configuration can be using molding or rolling, obtained vehicle window frame
Section configuration intensity is high, rigidity is good, indeformable, but its manufacturing procedure is complicated, and product cost is high.And occur now using it
He produces door sash at method, such as a kind of molding side for aluminium alloy car door and window frame that China Patent No. is CN90107331.8
Method, it is one end squeezing type membranous type using the method for " squeezing curved " by the sectional material blank of aluminium alloy car door and window frame from type film
Chamber, thus acquisition and the consistent sectional strip of type chamber, which can be hyperspace geometry, using this side
Method processing sectional material blank can prevent from wrinkling and collapsing, and can also eliminate the rebound of product, can save large complicated special purpose machine tool and big
Subsidiary engine accessory is measured, the production cost of equipment investment and product is reduced, and can guarantee the quality of product product well, but this side
The model of method is whole window frame model, may be only available for same vehicle window frame, use scope is small, and the hyperspace of itself is several
What shape easily generates uneven when embryo material is pressed into or is difficult to the situation being pressed into, and therefore, improves to the method, invention one
Applied widely, the uniform in quality of kind, the small automobile sash production technology of production difficulty have great importance.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kind of automobile sash production technologies.
To achieve the purpose of the present invention, technical scheme is as follows:
A kind of automobile sash production technology, comprising the following steps:
(1) it squeezes sill course: the embryo material of door sash is pressed into pattern die cavity from one end of pattern, after cooling, demoulding,
Sill course can be obtained;
(2) it combines sill course: the sash bar combinations that step (1) obtains at arc side triangle, quadrilateral shape or is not advised
Then arc side shape, and joined end to end by welding to get door sash frame is arrived;
(3) car door assembles: by the inner plate of car door and door skin of punch forming, by inner plate of car door and door skin group
Door lock striker plate is synthesized, combines door sash frame up and down with door lock striker plate and is connected;
(4) electrophoretic painting: water soluble paint is put into electrophoresis liquid, is door lock striker plate and car door by electrophoretic coating device
Sash frame carries out film;
(5) seam allowance gluing: gluing is carried out using glue rifle in the gap that each section is fitted and connected region and blocks seam allowance processing, only
After the completion of mouth gluing, the sealant for overflowing seam allowance is shaved with plastic scrapers;
(6) it dries: step (5) being sent into an oven through the door sash frame of seam allowance gluing with door lock striker plate and is done
It is dry, solidify coating paint and everywhere gluing;
(7) it seam allowance touch-up paint: using the paint vehicle with car body coating same color after drying, is applied in cured door sash seam allowance
Spraying touch-up paint is carried out on glue, is dried again;
(8) sealing strip is installed: loading onto sealing strip along door sash frame inner ring to get automobile sash.
Preferably, pattern can be arc line shaped or linear type in the step (1).
Preferably, embryo material can be aluminium alloy or steel plastic-aluminum alloy in the step (1).
Preferably, the pressure of embryo material indentation pattern die cavity is 0.6-0.8MPa in the step (1).
Preferably, the combination of sill course may be riveting in the step (2).
Preferably, logical between inner plate of car door and door skin, door sash frame and door lock striker plate in the step (3)
Welding is crossed to be combined with each other.
Preferably, sealant used in seam allowance gluing is PVC sealant in the step (5).
Preferably, the temperature that baking oven is dried in the step (6) is 160-180 DEG C, baking time 30min.
Beneficial effect is: the present invention is a kind of automobile sash production technology, by the way that embryo material is pressed into certain shapes
Die cavity in formed different model sill course, then by sill course carry out it is various combination form vehicle window frame of different shapes,
Not only production process is simple, is not necessarily to big scale production equipment, and applied widely, uniform in quality.Wherein, by Mr. embryo material
The linear type or arc line shaped sill course for producing into different model are easier to reality at complicated space structure with existing directly " squeezing curved "
It is existing, and extruded length is small in extrusion process, and product quality is more uniform;Film spray painting processing is carried out using electrophoretic painting to apply
Fill high-efficient, paint loss is small, uses water soluble paint, using water as dissolving medium, saves a large amount of organic solvents, drops significantly
Low atmosphere pollution and environmental hazard, safety and sanitation;Door sash each section is fitted and connected the gap in region due to can not meet
The requirement of electrophoresis permeability ratio is difficult to realize complete paint layer coating in electrophoretic painting, therefore electrodeposited paint film is relatively thin even without electricity
Swim paint film, and the more other regions of annealed zone corrosion resistance around solder joint are weaker, automobile in use, door and window frame region
Rainwater can be often contacted, and automobile door and window frames fixing structure, there are cavity, rainwater herein easily stay by storage, be easy to cause corrosion, because
This, the service life that can effectively extend door sash is sealed using gluing in stop portion.
