Manufacturing technology of glass pot cover

Abstract

The invention discloses a manufacturing technology of a glass pot cover. The method comprises the following steps of: firstly preparing a main steel ring and toughened glass; reducing the cutting length to 1.0-2.0mm according to the theoretical size of the steel piece; welding the two ends of a ring carrier steel strip together by a welding machine; lengthening the perimeter of the welded ring carrier by 1.0-2.0mm by a lengthening machine; curling the R position toward the outer circle by a curling machine, wherein the curled R position is required to be matched with the foot position of the toughed glass, and the tolerance is controlled within 0.2mm; folding the curled R position by a punch so that the ring carrier curled R positions are overlapped without clearance, wherein the overlapped R' position and the curled R position have equal width; polishing to obtain a ring carrier; and finally performing forming processes of ring sleeving, glass sleeving, edge covering and the like to obtain the glass pot cover. The manufacturing technology disclosed by the invention is simple and has high yield and production efficiency; and the manufactured glass pot cover ensures the seamless close contact between the ring carrier and the toughed glass, so that the glass pot cover does not hide dirt and dust easily.

Description

technical field [0001] The invention relates to a manufacturing process of a glass pot cover. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for cooking utensils. Glass pot lids are very popular because they can easily observe the situation in the pot through tempered glass. The traditional glass pot lid structure is as follows: Figure 1~Figure 2 As shown, it includes tempered glass 1a and the main steel ring 3a arranged on the outer edge of tempered glass 1a, the main steel ring 3a is composed of outer rib 31a for fixing tempered glass 1a and inner rib 32a corresponding to the pot mouth, outer rib 31a It is connected with the inner rib 32a by a horizontal rib 33a, and the inner wall of the horizontal rib 33a forms a pressing table, on which the tempered glass 1a rests, and is pressed and fixed by the crimp 34a at the top of the outer rib 31a. But this will produce a problem, in order to make the w...

Problems solved by technology

However, if this glass pot cover is produced by a commonly used manufacturing process, there is no way to ensure seamless contact between the ring and the tempered glass, resulting in low yield and low productivity
