Abstract

The invention discloses a seamless hinge and a machining method thereof. The seamless hinge comprises a plurality of blades and a rotating shaft which are integrally designed, wherein the blades are arranged on the rotating shaft in a sleeving mode and can rotate relative to the rotating shaft; each blade comprises a rotating part and a connecting part used for being connected with a door and a window; each rotating part is provided with a groove hole or a through hole used for being connected with the rotating shaft in an inserted mode; and the joints of the rotating parts and the connectingparts are smooth curves or in a step shape or in a combination mode. According to the seamless hinge and the machining method thereof, split type design is adopted, the hinge is mounted in a detachable mode, and the advantage of convenient installation is achieved; the step-shaped design of the connecting parts is easy to fix, the accuracy rate of multiple points and one line is high, and the labor cost is saved; the hinge is convenient to weld firmly and does not sink; and the blades are of a hot-rolled integrally-formed structure and have the advantages of being large in welding area, largein stress area and high in bearing capacity.

Description

technical field [0001] The invention relates to the technical field of door and window parts manufacturing, in particular to a seamless hinge and a processing method thereof. Background technique [0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between them. Hinges can be constructed of movable components, or of collapsible material. Hinges are often used frequently in daily life production and industry, and the hinge as a transmission is very important. The composition of its material determines the use effect and service life. Ordinary hinges are usually made of steel, iron, aluminum, etc. Typical or common existing technologies include: [0003] Such as CN105290733A discloses a kind of manufacturing method of hinge, this method comprises the following steps: 20-30 parts of iron ore and 12-19 parts of aluminum ore, carry out primary screening, pass 800-1000 mesh sieve, then smelt into ferrous metal by...
