Description

Technical Field

[0001] This invention relates to the field of tempered glass cover manufacturing technology, specifically to a one-time molding method for tempered glass covers. Background Technology

[0002] Tempered glass lids are widely used in kitchenware because they are less prone to greasy and dirty stains, can be mass-produced, and are less expensive than frosted glass lids. Tempered glass lids come in a variety of sizes. Currently, the glass used to make tempered glass lids is flat glass. This is done by cutting flat glass into round glass sheets on a production frame, achieving a utilization rate of about 60%. After edge grinding and drilling, the sheets are heated to about 800 degrees Celsius to be tempered. This process results in a large amount of broken glass, low material utilization, high labor costs, and significant energy consumption, leading to high manufacturing costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a one-time molding method for tempered glass covers. The purpose is to melt the raw materials for glass production and then mold and temper them in one go, thereby reducing costs and saving energy.

[0004] To solve the above-mentioned technical problems, the present invention provides a method for one-time molding of tempered glass covers, comprising the following steps:

[0005] S1. The raw materials for glass production are melted into glass liquid at 1180-1220℃ in a glass melting furnace. After being cut into the corresponding weight by a servo shear according to the size of the glass cover, the glass liquid enters the press through the glass material channel and is pressed into the required glass cover prototype in one go. Then the concave surface is polished with natural gas to make the surface smooth.

[0006] S2. Using a reversing robotic arm, the glass cover prototype after flame polishing is taken from the press mold to the cup mold. After drilling holes with a laser machine, the convex surface is polished with natural gas to make the surface smooth.

[0007] S3. The glass cover prototype is flame-blasted to 790-810℃ and then sent to a tempering blower via a conveyor belt for tempering and forming.

[0008] S4. After molding and tempering, the product is cooled and then fitted with a steel ring to obtain the finished product.

[0009] The advantages of this invention compared with the prior art are as follows: This invention adopts a melting, quantitative and molding method, which can quickly produce a glass cover prototype, and then process it into a tempered glass cover through a fire polishing tempering process. The finished product has good quality, greatly improves the utilization rate of raw materials, avoids waste, reduces energy consumption, greatly reduces costs, improves production efficiency, and can produce different specifications and sizes as needed. The solution is reasonable and easy to implement, and has good practicality. Detailed Implementation
