Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing, protection scope of the present invention is not limited to the following:

[0018] Such as Figure 1~5 Shown, a kind of preparation method of basalt fiber leaf spring, it may further comprise the steps:

[0019] S1. Establish a three-dimensional model of the leaf spring according to the requirements of the leaf spring;

[0020] S2. To make the upper mold, first take a die A, and then mill the lower surface of the die A to form a cavity 2 that matches the profile of the upper surface of the leaf spring 1, and then mill the two ends of the cavity 2 to form a horizontal A cavity A3 with a semicircular cross-section, and finally process two strip-shaped grooves 6 with variable cross-section at the bottom of the cavity 2, so as to make an upper mold;

[0021] S3. To make the lower mold, first take a die B, then mill the upper surface of the die B to form a boss 4 that matches the

Abstract

The invention discloses a preparation method of a basalt fiberboard spring. The preparation method comprises the following steps: (S2) an upper mold is manufactured; (S3) a lower mold is manufactured; (S4) the upper mold and the lower mold are filled with materials, and molding cores are mounted in the upper mold and the lower mold; and the top of a boss (4) and a cavity B (5) are filled with mixed materials consisting of resins, basalt fibers and fiber cloth; mixed materials consisting of resins, basalt fibers and fiber cloth are fully filled in a molding cavity (2), a cavity A (3) and a variable-section strip-shaped groove (6); the upper mold is buckled at the top of the lower mold; it is guaranteed that the cavity A (3) is matched with the cavity B (5) to form a complete hollow circle; and a molding core (7) is inserted in the hollow circle to realize material filling and molding core installation in the upper mold and the lower mold; and (S5) the basalt fiberboard spring is molded by compression. The preparation method has the beneficial effects of the simple manufacturing process, reduction of the production cost, higher rigidity and strength and prolonging of the plate spring service life.
