Abstract
Description
【発明の詳細な説明】 (産業上の利用分野) 本発明は車両用バンパーの製造方法に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for manufacturing a vehicle bumper.
(従来の技術)
車両用バンパーは一般にバンパーフェースとこのバンパ
ーフェースを支持するバンパービームから構成される。(Prior Art) A vehicle bumper generally includes a bumper face and a bumper beam that supports the bumper face.
また最近ではポリエチレン、ポリプロピレン等の剛性に
優れた熱可塑性樹脂によってバンパーを成形するように
したものがある。Recently, some bumpers have been molded from thermoplastic resins with excellent rigidity, such as polyethylene and polypropylene.

の溶融部を突合せて圧着することが知られている。Conventional child actors for joining bumper faces and bumper beams made of thermoplastic resin have not only joined them with adhesive or mechanical means such as screws, but also melted the joint surfaces of the two with a heater. However, it is known that the fused portions are brought together and crimped.
(発明が解決しようとする問題点)

、或いは溶融部に炭化物等の異物が混入し接着強度が低
下する不利がある。(Problems to be Solved by the Invention) The joining method using the heater described above involves bringing the panel heater into contact with the joining surfaces of the bumper face and bumper beam,
Since the contact part is melted, there are disadvantages such as molten resin adhering to the panel heater and causing dirt or smoke, or foreign matter such as carbide getting mixed into the molten part, reducing adhesive strength.
これを解消すべく、パネルヒータ表面にテフロンをコー
ティングすることも考えられるが、テフロンが剥れ易く
、このためパネルヒータを定期的に交換しなければなら
ない。In order to solve this problem, coating the surface of the panel heater with Teflon may be considered, but Teflon easily peels off and therefore the panel heater must be replaced periodically.

圧着するようにした。(Means for Solving the Problems) In order to solve the above problems, the present invention uses a heater to connect the joint surfaces of a bumper face and a bumper beam, which are separately molded from thermoplastic resin, without contact, that is, to separate the heater from the joint surface. In this state, they were heated and melted, and then their molten surfaces were brought together and pressed together.

フェースとバンパービームとが溶着一体化する。(Function) The heater is positioned at a predetermined distance from the joint surface of the bumper face and bumper beam. Then, each joint surface is melted by heat rays such as infrared rays from the heater. By pressing this molten surface and cooling it, the bumper face and bumper beam are welded and integrated.
