Description

In the proposed mechanism for gput sheet glass, made in the vnde mounted on the trolley of the interchangeable template, squares are mounted on the walls of the trolley, supporting the glass sheet with the aim of centering its relative template. The clamping of the edges of the softened sheet to the pattern is produced by means of horizontally movable irs.

In the schematic drawing of FIG. 1–4 and. Non-transverse incisions of the mechanism for bending sheet glass H1) and various positions of the latter in the process of operation are engraved.

On trolley 1, a replaceable template 2 is installed, and on the carriage steaks, movable support squares 3 are simulated. On the carriage of the carriage there are devices in the form of pipes 4, which cannot be moved horizontally and serve to press the sides of the sheet to the template 2.

Sheet glass cut to a given size is placed on squares 3. The pipes 4 for adjusting the iris are retracted as far as possible from the pattern 2 (Fig. 1). Trolley with pattern and glass

served in an oven. The glass in the furnace under the action of an appropriate temperature, which ranges from 600 to 850. It softens. II sags down to the middle and goes down to pattern 2 (Fig. 2). The edges of the glass start to lie on the squares 3; As soon as the glass is {middle} on the template, the carbon ni 3 and stepwise but are moved to the sides by means of this or that device, for example, fitting dies and gears to them.

The glass, which is not supported by the edges of the squares, begins to bend already in the opposite direction, i.e., the edges of the glass are bent by the action of their weight and temperature, facilitating the posting of the glass (Fig. 3).

The glass adheres to the bending of the template; the flanges of the glass, which have almost reached the template, are bent and aligned with the template by means of tubes 4 for pressing (Fig. 4). The pipes 4 press the glass to the pattern at their movements by means of, for example, toothed gear racks which are included in the markup with rotational gears.

The subject matter of the invention. 1. A mechanism for bending sheet glass B in the form of a replaceable template mounted on a carriage, characterized in that, in order to center the glass sheet relative to the template, on the walls

trolleys are mounted and support squares 3,

2. Under mechanicalism in and. 1 and the application of horizontal-movable elements for the purpose of irrizhimi boards softened sheet to the template.
