该曲率的测量很大程度上与测量技术有很大的关系，Glasstech保留在必要的情况下要求更改测量技术的权力。 ? Additionally, the accuracy of the curvature is largely dependent upon the tooling itself and the operator’s skill and operating the GLASSTECH SYSTEM.

另外，曲率的精确度也取决于机床本身、操作人员技术和对GLASSTECH 系统的操作。

? The system is capable of producing glass meeting the fracture requirements of ECE R-43 Standard (forty to four hundred [40-400] particles in five centimeters [5cm] square for lites three and five-tenths millimeters [3.5mm] or less thick). Specifically includes three and two tenths millimeters [3.20 mm] plus or two tenths (0.2mm) thickness minus zero tenths (0.0mm) thickness, to produce glass lites meeting the fracture requirements of the American National Standards Institute Z26.1-2004 Fracture Test # 7.

??该系统生产的玻璃，符合ECE R-43标准有关玻璃破碎的要求（3.5mm以内厚度的玻璃，5平方厘米内40-400个碎片）。

2.1.12 Optics:

? The system is capable of producing glass meeting or exceeding all ANSI and ECE specifications for tempered glass, all glass parts to be run tin side down, cut side up. Glass may be run tin side up if a silver ceramic paint is required; however, this may affect transport of glass through the bender section and bender positioning accuracy.

2.1.13 Decoration:

? The system is able to bend and temper parts with ceramic obscuration bands as presently in widespread

commercial use. The system is also able to bend and temper parts having silver ceramic conductive grids without damage to the appearance or electrical continuity of the grids.

3. External Press Bender (EPB) Component Description 外压折弯机部件介绍 3.1 Purpose: 目的

3.1.1 This chapter is intended to work in conjunction with the General Glasstech System Component Description chapter in this manual to describe the

components used in the Glasstech External Press Bender (EPB).

本章节旨在介绍Ｇlasstech系统中外压折弯机部件。

3.2 Components: 部件

3.2.1 The figure shown below is a general representation of the overall system structure. The following item

descriptions will expand on the functions of each of the individual subsystems that comprise the External Press Bending (EPB) system.

以下图示代表整个系统结构。构成以下外压折弯机系统的各个独立子系统将在以下内容中详细介绍。

3.2.2 Load Table / Load Jaws 上片台/上片钳夹

A load of glass is placed onto the load table load jaws. The load jaws are

preposition so that the centerline of the glass aligns with the centerline of the furnace. When the system is ready to process the next piece of glass the load jaws retract, dropping the glass onto the moving load table conveyor. The next piece of glass is then load onto the load jaws.

将玻璃片置于上片台上的上片钳夹中。为使玻璃片中线与钢化炉中线对齐，前置上片钳夹以固定。外压折弯机系统准备工作时，松开钳夹，玻璃片落于移动的上片输送机上。下一玻璃片装置上片钳夹中。

?

3.2.3 Furnace

? The furnace sections are where the glass is heated to a specified temperature. The elevated temperature will relax the glasses internal stresses to allow for tempering. The heating with in the furnace is divided in to two sections.

3.2.4 High Speed Run Out (Index Conveyor)

? The High Speed Run Out, located in the last two furnace zones, is where the line speed is increased to the final exit velocity of 1400mm/sec.

3.2.5 Bender

? The bender section is where the glass is bent to the desired shape. With the EPB, the bender is a modular device designed for the quick removal of the existing module to an off-line station for tooling changeover. ? Each module tooling is set-up for a specific part. ? The module can be set-up and tested while off-line. Two off line stations are provide, each with its own bender and control panel.

3.2.6 Mold

? A curved mold presses the glass on the press ring to achieve the desired shape. ? The mold uses a vacuum to lift the glass off the press ring and assist in forming the

central portion of the glass.

? The mold drops the glass onto the quench ring. 3.2.7 Bender Conveyor

? The bender conveyor consists of numerous individual rollers.

? Each of the individual rollers is removable, allowing for the installation of various press ring assemblies.

3.2.8 Press Ring

? The press ring supports the glass during the pressing operation.

? The press operation presses the glass to achieve the proper perimeter shape.

? The press ring resides below the bender conveyor until the glass reaches a position directly above the ring. At this point the ring elevates, lifting the glass above the conveyor towards the mold. The mold is in turn lowering from its home position to contact the press ring. 3.2.9 Quench Ring Shuttle

? The quench ring shuttle holds and transports the quench rings from the bender through the quench then onto the cooler.

? There are three quench rings present on the quench ring shuttle.

3.2.10 Quench

? The quench uses a high-pressure sweep quench for the tempering process through the application of air to the upper and lower surfaces of the glass.

? The quench has a clamshell feature that allows the blast heads to open and close around the quench ring. This allows for easy access for cleaning, maintenance and setup.

? The quench blastheads are configurable to match the curvature of the bent part through the use of a template. The template is part specific and is inserted at the beginning of a new part run.

3.2.11 Glass Catcher Bars ? The glass catcher bars are located over the Quench Ring shuttle at the blow up area and hold the glass until it falls onto the cooler conveyor.

3.2.12 Cooler ? The cooler is used to reduce the temperature of the glass to safe handling temperatures. The cooler is normally divided between Kevlar

covered rolls and rubber coated rolls. The cooler also transports the glass to the unload area.

3.2.13 Unload ? The unload area is located at the end of the cooler conveyor. It has rubber-covered conveyor rolls designed to prevent the glass from being scratched during unloading.

3.2.14 Off-Line Press Stations ? The off-line press stations are used to setup and test the bender module before is it inserted into the system. The stations contain all of the necessary equipment to functionally test the bender module during a part change over. The stations also allow for the pre-heating of the mold to cut-down on the change over time.

3.2.8 Press Ring

? The press ring supports the glass during the pressing operation.

? The press operation presses the glass to achieve the proper perimeter shape.

? The press ring resides below the bender conveyor until the glass reaches a position directly above the ring. At this point the ring elevates, lifting the glass above the conveyor towards the mold. The mold is in turn lowering from its home position to contact the press ring. 3.2.9 Quench Ring Shuttle

? The quench ring shuttle holds and transports the quench rings from the bender through the quench then onto the cooler.

? There are three quench rings present on the quench ring shuttle.

3.2.10 Quench

? The quench uses a high-pressure sweep quench for the tempering process through the application of air to the upper and lower surfaces of the glass.

? The quench has a clamshell feature that allows the blast heads to open and close around the quench ring. This allows for easy access for cleaning, maintenance and setup.

? The quench blastheads are configurable to match the curvature of the bent part through the use of a template. The template is part specific and is inserted at the beginning of a new part run.

3.2.11 Glass Catcher Bars ? The glass catcher bars are located over the Quench Ring shuttle at the blow up area and hold the glass until it falls onto the cooler conveyor.

3.2.12 Cooler ? The cooler is used to reduce the temperature of the glass to safe handling temperatures. The cooler is normally divided between Kevlar

covered rolls and rubber coated rolls. The cooler also transports the glass to the unload area.

3.2.13 Unload ? The unload area is located at the end of the cooler conveyor. It has rubber-covered conveyor rolls designed to prevent the glass from being scratched during unloading.

3.2.14 Off-Line Press Stations ? The off-line press stations are used to setup and test the bender module before is it inserted into the system. The stations contain all of the necessary equipment to functionally test the bender module during a part change over. The stations also allow for the pre-heating of the mold to cut-down on the change over time.
