Problems solved by technology

Using plate stamping to process the core body process, there are mainly core body ( figure 1 ) "A-A" section is not accurate enough for the size of the diagonal, the size of the spring core is not easy to control when it is placed in the shell of the spring glasses temple; the dimensional accuracy of the core body can be guaranteed by wire electric discharge cutting, but the production cost is high, so it is not suitable Mass production

Embodiment Construction

[0038] Such as figure 1 with figure 2 As shown, the spring core for elastic spectacle legs made by the present invention includes parts such as a core body 1, a slotted tube 2, a helical compression spring 3, and a sealed tube 4; the slotted tube 2, the helical compression spring 3, and the sealed tube 4. Sleeve on the core body 1 in turn. The tail of the core body 1 is flattened and rounded to form a stopper 14. The upper end of the core body 1 is drilled with a small hole 12. The diagonal dimension accuracy of the spring core is compared with high, see image 3 shown.

[0039] According to the thickness of the spring core used for elastic spectacle feet, choose zinc white copper or stainless steel plate, and use the punching method to cut the plate into the length and width of the core body 1 blank, and then put the core body 1 blank into the ultrasonic cleaning and vibrating machine Internal coarse vibration; at this time, the schematic diagram of the front structure of...

Abstract

The invention relates to a method for producing spring core used in flexible earpiece, belonging to the glasses technique, which can solve the problems as low accuracy and inability for batch production. Wherein, said method comprises following steps that: a, preparing blank; b, drilling and chamfering; c, milling the belly edge and chamfering; d, milling guide rod and rounding the guide rod; e, milling R and roughly rolling; f, machining the outer circle of guide rod; g, installing and punching the tail part to flat or round. The inventive spring core has high angle size accuracy, to control the space between the spring core and the frame of earpiece, while it has simple process, lower cost and the application for batch production.

Description

technical field [0001] The invention belongs to the technical field of spectacles, and relates to a method for manufacturing spectacles parts, in particular to a method for manufacturing elastic spring cores for spectacle legs. Background technique [0002] Everyone knows that the elastic spectacle temples have the following characteristics: when worn, the elastic spectacle temples can be pulled outward at a certain angle, so that the outer ends of the spectacle temples are opened, so that the user can wear them. When the glasses feet are released, the outer ends of the two glasses feet are pressed together by the elastic force of the spring, so that the glasses are firmly worn on the user's head. [0003] The foot body in the elastic glasses foot is hinged with a hinge through a spring core. Such as figure 1 As shown, a common spring core is composed of a core body 1, a grooved small tube 2, a helical compression spring 3 and a sealed small tube 4. Among the spring cores,...
