Abstract
The invention discloses a sunshade curtain coil spring for a vehicle skylight and a preparation method thereof. The sunshade curtain coil spring comprises a support bar; a clamping head is integrallymolded at one end of the support bar; a bending head is integrally molded at the end, far from the clamping head, of the support bar; the support bar, the clamping head and the bending head all adoptstainless steel strips; layer bodies are arranged on the surfaces of the support bar, the clamping head and the bending head; and wear resisting layers, antirust paint layers, galvanized layers and elastic strength reinforcing layers are arranged in inner cavities of the layer bodies in sequence from outside to inside. Through cooperation of the wear resisting layers, the antirust paint layers, the galvanized layers and the elastic strength reinforcing layers, the overall elastic strength and the rust and wear resistance of the coil spring are improved, and the use effect of the coil spring isimproved; and through the flow steps of support bar-punching-surface sand blasting-primer spraying-baking-extruder TPE layer coating-steel strip wire drawing-polishing-guide wheel loading-winding wheel molding-breakage molding, the molding effect of the coil spring is improved, and the coil spring is once molded.
Description
technical field [0001] The invention relates to the technical field of sunshade curtains, in particular to a sunshade coil spring for an automobile sunroof and a preparation method thereof. Background technique [0002] Coil spring: It can continuously provide a large restoring force in a small space, and can return the mechanical part to its original position after one stroke is completed to prepare for the next stroke. It is currently widely used in garden tool starters, vacuum cleaners and automobiles Take-up parts such as sunshades. [0003] When an automobile manufacturer produces a car, it is necessary to assemble a sunshade for a car with a sunroof. However, the coil spring is an important restoration part of the sunshade assembly. The coil spring produced according to the existing coil spring preparation method is poor in use and cannot be used for The overall elastic strength of the coil spring is enhanced to reduce the elastic recovery effect of the coil spring, a...
