Description
Technical field
The present invention relates to automobile part production technique field, particularly relate to a kind of automobile armrest production technology.
Background technology
The fast development of modern automobile technology, in order to improve the degree of utilization of finite space in automobile, people arrange armrest usually in the middle of two automotive seat, for drive personnel or by bus personnel hand to be placed on it rest, and by paper handkerchief, add in accommodation space that the foreign material such as cooking oil coupon are accommodated in armrest to save space, like this, the handrail of armrest just needs frequently to be opened, in order to improve the comfort of armrest and effectively reduce the wearing and tearing of handrail, usual needs are at the coated leather sheath of the upper surface of handrail, with the service life of extension handrail, improve the comfort of handrail.
But, existing handrail mainly adopts polyurethane foam technique to reach the soft sense of touch effect of matter, but it needs the exploitation of equipment investment and foaming mould in earlier stage, not only the R&D cycle is longer and expense is larger, and whole production process is longer for man-hour, need to paste the operations such as the anti-leak-stopping material of U.S. line paper, foaming, polishing overlap, work efficiency is low, and productive costs is high.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of automobile armrest production technology is provided, there is work efficiency high, the advantage that productive costs is low.
The present invention is achieved through the following technical solutions.
A kind of automobile armrest production technology, comprises following procedure of processing:
Steps A, choose cladding and sponge; Particularly, described cladding is PVC leather or PU leather, and described sponge is polyethers sponge or polyester sponge, and is evenly provided with breather hole in sponge.
Preferably, described sponge comprises the raw material of following weight portion:

Step B, according to the profile of automobile armrest upper cover, cladding and sponge to be cut out, make the surface of the complete coated automobile armrest upper cover in the surface of cladding and sponge, and the face area of cladding, sponge is greater than the face area of automobile armrest upper cover, for coated operation is prepared.
Step C, carry out glue spraying, baking on one of them surface of sponge, then sponge is coated with the upper surface of surface mount at automobile armrest upper cover of glue, makes sponge entirely be coated on the surface of automobile armrest upper cover.
Step D, first cladding is carried out prebake conditions, then glue spraying, secondary baking is carried out on one of them surface of cladding, then surface mount cladding being coated with glue, being coated with the upper surface of automobile armrest upper cover of sponge, makes cladding entirely be coated on the upper surface of sponge; Bag is attached to the cladding that automobile armrest covers and wants tensioning face that gauffer can not be had to produce or bulge, and the edge of automobile armrest upper cover will stretch and put in place.
Particularly, the specification of sponge is (200-220mm) x(200-220mm), the specification of leather is (300-350mm) x(275-300mm), the glue quantity of step C and step D is 20-30g.
Step e, edge along cladding and sponge, stretch cladding and sponge leveling, then carries out nailing by nail gun and fix, cut off unnecessary cladding and sponge, guarantee sponge and the coated leveling of cladding of automobile armrest upper cover, surface does not have fold or bulge phenomenon, and automobile armrest upper lid surface planeness is high.
Step F, assembling: the automobile armrest upper cover after step e being processed is assembled on armrest seat, obtained automobile armrest.Without slide rail automobile armrest: install appliance for releasing single block at the back side of the handrail of coated good cladding, then carry out screwing with electric screwdriver and fix.Slide rail type automobile armrest: slide rail be fixed-is assembled another fixed block-installation appliance for releasing single block at the back side mounting plate-cylinder-pressing handrail of the handrail of coated good cladding and adapter plate-installation slide rail-electric screwdriver---electric screwdriver screws fixing-mounting base.Then, the automobile armrest assembled is arranged on console: first on console, box is installed, then fixed armrest, electric screwdriver screws fixing.
Wherein, described step B is 500 ~ 700s to the overhours of step e, and preferably, overhours is 650 ~ 700s.
Wherein, described cladding comprises the raw material of following weight portion:
