Punching forming die for semi-framed glass rings

Abstract

The invention relates to a punching forming die for semi-framed glass rings. The punching forming die for the semi-framed glass rings comprises an upper die and a lower die, wherein the lower die comprises a base and a punching seat; the punching seat is provided with a bench; a punching forming seat is installed on the bench; the punching forming seat comprises a lower forming block, a middle forming block and an upper forming block which are sequentially arranged from bottom to top; a notch is formed in the middle forming block; an upper open port and a lower open port of the notch are shielded by the lower forming block and the upper forming block to form side ports allowing a machining part to be punched to stretch in; punching holes are formed in the upper forming block; lower discharge holes are correspondingly formed in the lower forming block; the diameter of each lower discharge hole is not less than the diameter of each punching hole; a discharge channel communicating with each lower discharge hole is formed in the base; punching forming parts are installed on the upper die; each punching forming part is provided with a punching part installation seat and a punching tool;and each punching tool is adaptive to the corresponding punching hole. The punching forming die for the semi-framed glass rings and adopting the scheme is simple in structure, realizes the purpose ofbeing convenient to detach and repair through a simple design, achieves the purposes of being wide in applicability and convenient to use, and greatly saves the labor force.

Description

technical field [0001] The invention relates to spectacles, in particular to a punching mold for a half-frame mirror rim. Background technique [0002] Glasses are lens lenses embedded in the frame and worn in front of the eyes to improve vision, protect eyes or for decoration. Mirrors can correct a variety of vision problems, including nearsightedness, farsightedness, astigmatism, presbyopia or strabismus, amblyopia, etc. [0003] There are also many types of glasses. Spectacle frames can be divided into full-rim spectacle frames and half-rim spectacle frames. Half-frame spectacle frames are currently a very popular and popular spectacle style. The existing half-rim glasses are mainly composed of spectacle frames and spectacle lenses. The spectacle frames include a half-rim spectacle frame that matches the shape of the upper half of the spectacle lens. To fix the lenses, it is usually necessary to punch or drill a plurality of through holes on the half-frame plate for the...

Problems solved by technology

The existing half-rim glasses are mainly composed of spectacle frames and spectacle lenses. The spectacle frames include a half-rim spectacle frame that matches the shape of the upper half of the spectacle lens. To fix the lenses, it is usually necessary to punch or drill a plurality of through holes on the half-frame plate for the fish wire to pass through and bind and fix, that is, the half-rim spectacle frame needs to be punched, and there are many ways to punch holes , if a straight line is directly punched on it, since the wire is relatively thin, it is difficult to punch holes, and it will be damaged when it is bent into a semi-frame shape, resulting in defective products, which is difficult to produce. At the same time, the current mold has other Small applicability, difficult to operate, and occupy a large area
