The working principle of the basic scheme is as follows: when arc glass needs to be produced, the electric heating wire is turned on to heat the hydraulic oil, and the hydraulic oil transfers heat to the heating box through heat transfer, so that the temperature in the heating box is increased. And operating the power unit to drive the sliding rod, the upper supporting block and the lower supporting block to move downwards through the cross rod, placing the plate glass on the lower supporting block when the gap between the upper supporting block and the lower supporting block is positioned outside the discharge port, then operating the power unit again, conveying the plate glass to the heating box through the power unit, and closing the power unit when the discharge port is plugged by the lower supporting block. After heating for a period of time, the temperature of the plate glass is raised to the temperature which accords with bending forming, at the moment, the power unit is operated again, the power unit drives the sliding rod and the push rod to move downwards through the cross rod, and in the process, the extrusion plunger, the upper support block and the lower support block all move downwards together. In the process that the upper supporting block and the lower supporting block move downwards, the lower supporting block is gradually close to the push block, the lower supporting block applies acting force to the inclined plane on the upper side of the push block, and the push block extrudes the spring and then slides along the inside of the groove. When the plate glass between the upper supporting block and the lower supporting block moves to be opposite to the pushing block, the pushing block moves towards one side of the plate glass under the action of the spring, and the plate glass is pushed to the forming die by the pushing block, so that the plate glass is finally positioned on the forming die. Go up supporting block and bottom suspension bracer and continue downstream, go up the supporting block and exert the effort to the inclined plane of ejector pad upside, make the ejector pad slide along the inside of recess, avoid the push rod to limit and go up supporting block, bottom suspension bracer downstream. When the upper supporting block and the lower supporting block move downwards, the push rod drives the extrusion plunger piston to move downwards together, at the moment, the volume of the cavity is increased, the pressure in the cavity is reduced, the cavity is communicated with the cavity through a pipeline, the pressure in the cavity is also reduced, the ejection block is gradually pressed into the cavity under the action of external air pressure, and the ejection block is prevented from interfering with the bending forming of the plate glass. And when the extrusion plunger continues to move downwards, extruding the plate glass placed on the forming die to bend the plate glass into an arc shape. After the plate glass is bent into an arc shape, the power mechanism is operated, so that the power mechanism drives the extrusion plunger, the upper support block and the lower support block to move upwards together, when the extrusion plunger moves upwards, the extrusion plunger extrudes hydraulic oil in the cavity, the hydraulic oil flows into the concave cavity through the pipeline, the ejection block gradually extends out under the action of the hydraulic oil, and the ejection block ejects out the formed arc-shaped glass, so that the arc-shaped glass is separated from the forming die. And in the process of ascending the upper supporting block and the lower supporting block, the upper supporting block and the lower supporting block successively exert acting force on the inclined plane on the lower side of the pushing block to enable the pushing block to retract into the groove, when the pushing block abuts against the side face of the lower supporting block and the gap between the upper supporting block and the lower supporting block is still positioned outside the discharge port, the power device is closed, the plate glass is placed on the lower supporting block, then the power device is opened, and the plate glass is conveyed into the heating box through the power device. The flat glass can be continuously bent into the arc glass by repeating the operation.
The beneficial effect of this basic scheme lies in:
1. in the process of up-and-down movement of the extrusion plunger, hydraulic oil in the cavity continuously flows, so that heat transfer between the hydraulic oil is accelerated, the temperature of the hydraulic oil tends to be consistent, and the phenomenon that the temperature of the hydraulic oil near the electric heating wire is too high, so that the temperature in the heating box is uneven, and normal heating of the plate glass is influenced is avoided.
2. The time from the completion of the heating to the transfer of the plate glass into the forming unit is short, the temperature of the plate glass can be basically kept unchanged, and the condition that the glass is broken in the bending forming process due to the sudden temperature drop of the plate glass is avoided; and because extrusion plunger sliding connection is in the cavity, hydraulic oil gives the extrusion plunger with heat transfer, and extrusion plunger self has higher temperature, can also be to glass heat transfer when extrusion plunger extrusion glass, avoids glass to cool off fast.
3. After the plate glass is heated, the pushing block can automatically push the plate glass to the forming die, feeding by workers is not needed, and labor intensity of the workers is reduced.
4. After the plate glass is pressed into an arc shape, the ejection block can eject the arc-shaped glass, so that the arc-shaped glass is separated from the forming die, and the arc-shaped glass is convenient to take out.
5. In the heating process, the lower supporting block blocks the discharge hole, and in the discharging process, the upper supporting block can also block the discharge hole, the discharge hole is communicated with the outside only for a short time, the time for heat exchange between the gas in the heating box and the external gas is shortened, and the heat loss is reduced.
Furthermore, a baffle plate for limiting the glass is fixed on the side wall of the forming die. The ejector pad exerts the effort to glass, can carry out glass propelling movement to forming die on, and the baffle can carry on spacingly to glass, makes glass be located suitable position, and the setting of baffle has avoided glass to deviate forming die because of the atress is too big, guarantees the precision of arc glass processing.
