СПОСОБ И УСТРОЙСТВО ДЛЯ РАЗДЕЛЕНИЯ ЛИСТОВОГО СТЕКЛА

Номер: RU2370462C2

Изобретение относится к разделению листового стекла пламенем разогревающей горелки. Техническим результатом изобретения является получение высокого качества разделенных поверхностей листового стекла, снижение затрат при разделении листового стекла. Способ разделения листового стекла включает гравирование царапины в листовом стекле вблизи точки зарождения разделения воображаемой линии разделения, причем царапина служит в качестве точки зарождения трещины. После чего осуществляют нагревание вдоль воображаемой линии разделения части листового стекла с намеченной на ней воображаемой линией разделения пламенем разогревающей горелки, так что листовое стекло имеет температуру поверхности стекла 130°С или выше в качестве наивысшей температуры вблизи воображаемой линии разделения, а соотношение средней величины температуры на обеих кромочных частях полосы шириной 10 мм с центром около воображаемой линии разделения и наивысшей температуры сразу после нагревания составляет не менее 45%. Затем используют ...

To simplify and shorten the cutting of a glass plate 3 with the aid of a cutting tool 11 and the removal of a coating applied to the glass plate 3 with the aid of a grinding tool 12, the scoring of the glass plate 3 and the removal of the coating in strips located each side of the scoring lines and running parallel thereto are carried out in single step. In the apparatus proposed for this, the cutting tool 11 and the grinding tool 12 are mounted on a common support 8 which can be moved along a beam 5 over a support 2 for the glass plate 3. The grinding tool 11 is fastened to an auxiliary support 17 which can be swivelled around the axis 10 of the cutting tool 11, which axis is aligned perpendicularly to the support 2. ...

SCORING DEVICE HAVING A REFERENCING CARRIAGE

Номер: CA1079627A
Принадлежит: PPG INDUSTRIES INC, PPG INDUSTRIES, INC.

A glass scoring device includes a scoring head assembly and a carriage each pivotally mounted about an axis. The carriage has a pair of spaced wheels biased toward a glass ribbon and a support member. The support member biases a cutting force against the scoring head assembly to score a glass ribbon. Irregularities in the glass ribbon thickness and/or eccentric conveyor rolls oscillates the carriage and scoring head assembly about the axis. Oscillatory movement of the carriage scoring head assembly cooperate to maintain a constant cutting force on the scoring head assembly.

ON-LINE/OFF-LINE SCORING BRIDGE

Номер: CA0002608648C
Принадлежит: PPG INDUSTRIES OHIO, INC.

A scoring bridge includes a plurality of moveable mounted carriages. The carriages each have a rotor, and the bridge has a linear stator to move the carriages. The position of a carriage designated as a reference carriage is recorded as it moves past a motion detector. The position of each remaining carriages is recorded as they individually move past the detector. The difference between the position of a carriage and the position of the reference carriage is an offset that is added to the position reading of the carriage to accurately space the carriage form the reference carriage. Each of the carriages can have a scoring assembly that includes servomotor acting through a gear arrangement on a scoring wheel. The servomotor applies a constant load to the scoring wheel and adjusts the load for any positive or negative displacement of the scoring wheel from a reference position.

MULTI-LASER SYSTEM AND METHOD FOR CUTTING AND POST-CUT PROCESSING HARD DIELECTRIC MATERIALS

Номер: US20160059349A1

Laser processing of hard dielectric materials may include cutting a part from a hard dielectric material using a continuous wave laser operating in a quasi-continuous wave (QCW) mode to emit consecutive laser light pulses in a wavelength range of about 1060 nm to 1070 nm. Cutting using a QCW laser may be performed with a lower duty cycle (e.g., between about 1% and 15%) and in an inert gas atmosphere such as nitrogen, argon or helium. Laser processing of hard dielectric materials may further include post-cut processing the cut edges of the part cut from the dielectric material, for example, by beveling and/or polishing the edges to reduce edge defects. The post-cut processing may be performed using a laser beam with different laser parameters than the beam used for cutting, for example, by using a shorter wavelength (e.g., 193 nm excimer laser) and/or a shorter pulse width (e.g., picosecond laser). 1.
