Description

BACKGROUND OF THE INVENTION Field of the Invention [0001]

The present invention relates to an apparatus for chamfering chamfering chamfering, and more particularly to a method for machining four corners of a cupboard with a simple and low cost.

In general, plate glass is manufactured from tempered glass by reinforcing process for safety in cutting and using according to use.

The tempering process of the glass plate is made of tempered glass which has transparency by washing step, drying step, marking step, heat treatment step by heating furnace, and quenching step and is 4 ~ 6 times stronger than impact of ordinary glass.

In this case, the edges of the sharp edges are chamfered as pretreatment in order to prevent damage to the plate glass such as cracking or breakage of the plate glass due to the stress concentrated on the sharp edges cut in the heat treatment process of the plate glass.

As an example of a machining apparatus for a plate glass edge used in a reinforcing pretreatment process of a plate glass, there is disclosed an apparatus for chamfering a rotating diamond wheel.

The diamond wheel is made of a diamond material and is tapered from the upper and lower ends to the center. A driving motor is connected to the shaft. When the plate glass enters, the driving motor is driven to rotate the wheel. And the lifting and lowering means is connected to the shaft of the processing wheel so that the lifting and lowering operation is performed according to the thickness of the plate glass.

However, in the conventional chamfering edge chamfering apparatus, the abrasion must occur at the plate glass contact portion of the machining wheel. Therefore, it is necessary to change the machining chambers after the use to some extent. Since the machining wheel is made of expensive diamond material, And it takes a lot of equipment cost because several machining wheels of appropriate size are required according to the thickness of the plate glass.

In addition, since the height of the processing wheel must be adjusted according to the thickness of the plate glass, a separate elevating means is required, which complicates the apparatus, increases the probability of failure as much as it is,

In addition, a pressure sensor is applied to the edge chamfering apparatus of the conventional plate glass. When the chamfering of the plate glass through the processing wheel is mixed with the glass powder generated during chamfering, the pressure sensor malfunctions, There were also disadvantages that could not be supported.

In addition, since the rectilinear processing head of the edge chamfering device of the plate glass is positioned on the opposite side of the rotational direction of the rotary processing head, the width of the entire apparatus is increased, and the installation space is occupied.
