Drilling method for glass plate uneven in thickness

Abstract

The invention belongs to the field of glass drilling, and particularly discloses a drilling method for a glass plate uneven in thickness. The drilling method comprises the following steps that firstly, a drilling area needing to be drilled is determined, an elastic piece is fixed to a curved surface at the position of the drilling area on the glass plate, and the elastic piece and the glass plate are fixed together; secondly, the glass plate and the elastic piece are fixed to a clamp; thirdly, the axis of a drilling barrel is aligned with the center of the drilling area; and fourthly, the drilling barrel rotates and gradually gets close to the plane of the glass plate, cooling water is sprayed to the plane position of the glass plate, an annular grinding wheel on the drilling barrel makes contact with the plane of the glass plate and grinds the glass till the whole annular grinding wheel penetrates the glass plate, then drilling barrel continues to conduct machining, a conical disc on the drilling barrel makes contact with a hole, drilled just now, in the glass plate and conducts edge chamfering on the hole, and after the edge chamfering is over, a drilling barrel push cutter is adopted, and the drilling step is ended. Compared with laser machining, the machining method has the beneficial effects of being low in cost, convenient to operate and the like.

Description

technical field [0001] The invention relates to the field of glass drilling, in particular to a method for drilling glass plates with uneven thickness. Background technique [0002] With the advancement of technology, the application of glass is becoming more and more extensive, especially in recent years, the use of glass walls has become more and more extensive. The glass plate used on the glass wall is usually thick, so special attention should be paid when cutting. Due to the nature of the glass itself, if there is uneven force during the specific cutting process, the glass is prone to cracking or breaking. However, in the construction process of the glass wall, drilling the glass plate is an indispensable link, and the glass plate and the frame on the wall are fixed through the connecting hole through the flexible connecting piece. [0003] At present, there are usually two ways to drill holes in glass plates. One way is to use glass blades to cut directly, and the oth...

AI Technical Summary

Problems solved by technology

However, there are relatively great difficulties in drilling holes on glass plates with uneven thickness. Conventional glass blades are difficult to process. Because of the uneven thickness of glass plates, some parts have been cut off during cutting, while others have not. Cut off, if the use of external force to cut it off, it is easy to crack the glass plate

At present, the laser cutting method is mainly used to realize the drilling. However, the glass plate used for the glass wall is usually relatively thick, and the cost of laser processing is relatively high.
