Problems solved by technology

[0003] At present, the processing quality of the fillet corners of the overflow brick weir crest is affected by the machining error of the machining reference plane, and large or small fillets often appear. Small fillets will cause secondary processing, and large fillets will cause poor quality of the entire overflow block. Serious large rounded corners will also cause the entire overflow brick to be scrapped, which not only delays the production cycle, but also causes great economic losses

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0022] See figure 1 and figure 2 , the glass liquid overflows from the overflow groove of the overflow brick in the middle of the formed overflow brick 1, climbs over the fillet of the weir top of the overflow brick, flows along the straight overflow surface on both sides of the overflow brick to the inclined overflow surface, and The tips of the flow bricks merge into the substrate glass; the steps at both ends of the size are the reference plane and the support surface in the height direction when the overflow bricks are assembled in the forming furnace. as a height reference.

[0023] see figure 1 , 2, processing method of the present invention comprises the following steps:

[0024] Step 1: Set the length direction of the overflow brick as the X axis, the width direction as the Y axi...

Abstract

The measured size of a processing reference surface of the circular corners of the weir crest of an overflow brick is compared with a design size, so the polarization direction during processing of the four circular corners of the weir crest of the overflow brick can be ensured, uncontrollable phenomena in the processing of the circular corners of the weir crest are removed, production periods areensured and quality of the finished products of the overflow brick is ensured.

Description

technical field [0001] The invention belongs to the technical field of overflow brick finished product processing, and in particular relates to the processing quality of overflow brick weir crest rounded corners. Background technique [0002] The overflow brick is an irreplaceable key component in the process of producing liquid crystal glass substrates by the overflow down-draw method. To the tip of the overflow brick and merge into the substrate glass. The fillet processing of the weir crest of the overflow brick is the last process of the 45-day CNC machining period of the overflow brick. Its processing quality is very important, and large and small fillets are not allowed. [0003] At present, the processing quality of the fillet corners of the overflow brick weir crest is affected by the machining error of the machining reference plane, and large or small fillets often appear. Small fillets will cause secondary processing, and large fillets will cause poor quality of t...
