The action and effect of embodiment
The car door upper decoration plate rebate members Wrapping apparatus according to involved in the present embodiment, because there is positioning mechanism, turn over
Side mechanism, electrical conduction mechanism and control mechanism, wherein there is flange body the first flange unit, the second flange unit, third to turn over
Side unit, the 4th flange unit, the 5th flange unit, the 6th flange unit and the 7th flange unit, wherein turned over by second
Side unit and third flange unit, which can be realized, carries out bound edge to the first corner portion, the first crimp portion, passes through the 4th flange unit
Bound edge can be carried out to the second crimp portion and third crimp portion respectively with the 5th flange unit, it can by the 6th flange unit
Bound edge is carried out to the second corner portion, therefore, this equipment for wrapping can be realized in a limited space to car door upper decoration plate corner
Two corners and crimp of the edge part of component carry out bound edge, and decorative fabric and decoration framework after these position bound edges
It is good to be bonded effect.
Related Wrapping method will be pasted onto the outer of the edge part of car door upper decoration plate rebate members through this embodiment
The edge rim charge of decorative fabric on surface is overturn from the outer surface of edge part to the upper surface of edge part or inner surface, bound edge effect
Fruit is good, and operating method is simple, and bound edge is high-efficient.
Further, because third flange block has vertical sub- flange block and horizontal sub- flange block, horizontal sub- flange block
Length is less than vertical sub- flange block, and therefore, when third flange block carries out shift action to the left, vertical sub- flange block will state the
Edge rim charge on the upper surface in one crimp portion is pushed into the inner surface in the first crimp portion to the left, and also by the first corner portion
Edge rim charge on inclined-plane is pushed into the lower surface of the first corner portion to the left, and horizontal sub- flange block is by the edge side of the first corner portion
Material is pressed on the first corner portion corner side, so that the first corner portion and the decorative fabric patch coated in the first crimp portion
It is good to close effect.
Further, since the 4th flange block is inverted L-shaped, so the 4th turns over when the 4th flange block carries out moving down movement
Side block pushes the edge rim charge of the upper surface in the second crimp portion, covers it and is pressed in the inner surface in the second crimp portion
On.
Further, since the shape of the lower surface of the upper surface and third flange block of the extended segment of four flange blocks matches,
So four flange blocks and third flange block can carry out bound edge operation in narrow operating space.
Further, since the 7th flange block is inverted L-shaped, when the 7th flange block carries out moving down movement, the 7th flange block
The edge rim charge of the upper surface in the second straight flange portion is pushed, it is covered and is pressed on the inner surface in the second straight flange portion.
Above embodiment is preferred case of the invention, the protection scope being not intended to limit the invention.
