Abstract
A method for fabricating a spectacle frame made of a cellulose acetate sheet embedded with the metal piece, where the metal piece is embedded between a main material and auxiliary materials; the metal piece, the main material, and the auxiliary materials are tightly bonded by pressing by a hydraulic press. Since the metal piece is not in contact with a human body, there will be no corrosion problems. The composite plate structure resulting from splicing of the main material and the auxiliary materials have better mechanical performance.
Claims10
A method for fabricating a spectacle frame made of a cellulose acetate sheet embedded with a metal piece, the method comprising the following steps:
- S10:
- providing a main material, and punching a positioning hole in the main material, wherein the main material is the cellulose acetate sheet;
- S20:
- providing the metal piece, and cutting a first groove which is mated with the metal piece on the main material;
- S30:
- providing two auxiliary materials, and cutting the two auxiliary materials according to the metal piece;
- S40:
- planing one side of the main material as a first splicing surface;
- S50:
- aligning the main material with the auxiliary materials, and adhering the first splicing surface to one of the auxiliary materials with an adhesive to form a first semi-finished product;
- S60:
- after the adhesive is naturally dried, placing the first semi-finished product in an oven for low-temperature baking;
- S70:
- planing the other side of the main material of the baked first semi-finished product as a second splicing surface;
- S80:
- forming a second groove on the corresponding auxiliary material by cutting downwards along the bottom of the first groove of the first semi-finished product;
- S90:
- impregnating the first groove and the second groove with the adhesive, and then placing the metal piece in the first groove and the second groove, and adhering the second splicing surface to the other of the auxiliary materials with the adhesive to form a second semi-finished product;
- S100:
- after the adhesive is naturally dried, placing the second semi-finished product in the oven for low-temperature baking;
- S110:
- cutting the baked second semi-finished product;
- and
- S120:
- after cutting, placing the second semi-finished product in a die, then placing the second semi-finished product along with the die in the oven for baking so that the second semi-finished product is softened, and pressing the second semi-finished product by a hydraulic press to form a finished product.
