Manufacturing method for seamless steel ring of glass lid

Abstract

The invention discloses a manufacturing method for the seamless steel ring of a glass lid. The method comprises the following steps: 1), obtaining a steel belt with a vertical knife edge through a cutting and blanking machine; 2), carrying out laser welding, wherein the two ends of the steel belt are buckled by a buckle of a welding table, then a button is pressed so as to allow the well buckled steel belt to be rotated to the luminous positions of the laser welding, followed by the welding between the luminous starting point and the luminous ending point; 3) flatting welding joints, wherein a punch press is adopted to flat the deformation at the welding positions; 4) processing the surfaces of the welding joints, nylon is adopted to process the oxides on the surfaces of the welding joints; and 5), processing the welding joints again, wherein the welding joints of the formed steel belt are reprocessed by a carborundum wheel. The method provided by the invention has the advantages of simple process and high yield. Due to the adoption of the method, the obtained steel ring is seamless, which avoids that the hand is scraped by sharp joints and facilitates the cleaning so as to avoid the hiding of dirt and dust, and as a result, the corresponding food health security hidden dangers are avoided.

Description

technical field [0001] The invention relates to a method for manufacturing a glass cover seamless steel ring, and specifically belongs to the technical field of glass cover design and manufacture. Background technique [0002] The glass cover commonly used on cookware is generally composed of a tempered glass part and a steel ring inlaid with a metal ring. In the traditional welding process, the steel ring is welded by an energy storage welding machine. The energy storage welding machine converts electrical energy into Due to the influence of voltage instability during the welding process, it is very easy to cause the welding to be weak, and one place of the weld is easy to produce scratches, such as figure 1 As shown; in addition, the traces of the welding seam are very obvious, which reduces the appearance and commerciality of the glass cover product. Seam 1 is easy to breed a large number of bacteria, seriously affecting the hygiene of cooked food, and there is a certain...

[0002] The glass cover commonly used on cookware is generally composed of a tempered glass part and a steel ring inlaid with a metal ring. In the traditional welding process, the steel ring is welded by an energy storage welding machine. The energy storage welding machine converts electrical energy into Due to the influence of voltage instability during the welding process, it is very easy to cause the welding to be weak, and one place of the weld is easy to produce scratches, such as figure 1 As shown; in addition, the traces of the welding seam are very obvious, which reduces the appearance and commerciality of the glass cover product. Seam 1 is easy to breed a large number of bacteria, seriously affecting the hygiene of cooked food, and there are certain food safety hazards

In the prior art, if it is necessary to obtain a seamless steel ring for the glass cover, it is necessary to use steel sheets, cut them into discs, and use hydraulic presses and punching machines to produce them. The process is complex, dangerous, and costly.
