Problems solved by technology

[0002] Early spectacle frames were mainly made of copper alloy frames, among which cupronickel was the most commonly used material, and its disadvantages were easy corrosion and deformation
The advantage of the nickel alloy frame is that it has good corrosion resistance and is not easy to deform; but its disadvantage is that it is harder and heavier, and it is not easy to adjust

Abstract

The invention relates to a method for producing a stainless steel belt of a glasses frame, which comprises the following steps of: selecting a stainless steel belt blank; performing first rolling, second rolling and third rolling by adopting a four-roll precision rolling mill unit to roll a semi-finished stainless steel belt with thickness of 1.03 millimeters into semi-finished stripe stainless steel belt with thickness of 1.0 millimeter, wherein the thickness tolerance of the semi-finished stainless steel belt is + / -0.01 millimeter; cleaning, pulling and straightening the semi-finished stripe stainless steel belt into a finished stripe stainless steel belt; and shearing the finished stripe stainless steel belt into the width specification required by a user, and finally inspecting, packing and warehousing the finished product. The stainless steel glasses frame has good ductility, is easy to adjust, manufacture and process, lighter and more corrosion-resistant, and prevents the sweat from corroding the metal to lose luster in long-term wearing; and the method overcomes the defect that the physical property of the finished product is difficult to ensure in the prior art, and the obtained finished product Hv=250-290 meets the use requirement of customers.

Description

technical field [0001] The invention belongs to the field of production methods of stainless steel strips, in particular to a production method of 304 stainless steel strips for spectacle frames. Background technique [0002] Early spectacle frames were mainly made of copper alloy frames, among which cupronickel was the most commonly used material, but its disadvantages were easy corrosion and deformation. The advantage of the nickel alloy frame is that it has good corrosion resistance and is not easy to deform; but its disadvantage is that it is relatively hard and heavy, and it is difficult to adjust. Copper alloy frame is too easy to corrode, and although nickel alloy solves the problem of easy corrosion, its material is heavy, and it is still uncomfortable to wear. In order to solve the above problems, a new metal that is safer, lighter, more durable and more comfortable Material, stainless steel frame has been born accordingly, the frame made of stainless steel, its d...
