Description

The invention relates to building materials, namely glass industry, and can be applied in the production of bent tempered glass. five

The purpose of the invention is to increase reliability and simplify the design.

FIG. 1 shows a plant for horizontal pressing and tO tempering of sheet glass; FIG. 2 is a section A-A. FIG. 1 (the mechanism for moving flat and curved glasses in the glass pressing position is in the position after glass pressing, 15 the dotted line shows the position of the inclined rolls and glass in the mechanism before glass pressing); FIG. 3 is a section BB in FIG. 1 (mechanism for moving flat and curved glasses to 20 positions of quenching and cooling of glass).

The plant for horizontal pressing and tempering of sheet glass comprises a heating furnace 1, a glass pressing mechanism 2, a mechanism for moving 3 flat and bent glass, and a device 4 for tempering and cooling the glass.

 -Heating furnace 1. Represents one of the known constructions of 30 roller-arc furnaces.

The pressing mechanism 2 is a well-known design for the horizontal pressing of sheet glass: it consists of a contour cutting matrix 5 and a continuous punch 6 made into the curved surface of the glass.

The mechanism 3 for moving flat and curved glasses is a roller conveyor consisting of a series of horizontal rollers 7 rotating around its axis in guides 8, above each of which a pair of kinematically associated inclined rolls 9, kinematically connected with it, are located rotating around its axis in the guides 10. The transmission of torque from the gearbox 11 through the double hinge Hooke 12 and the roller 13 is carried out to the horizontal roller 7, covered with a heat insulating sheath transporting glass. Further, the torque is transmitted through a double hinge.

Inclined rolls 9 with heat insulating sheath, having the ability to move along the axis of the hollow rolls 17. Inclined 9 and horizontal 7 rolls transport the formed glass sheets 18. The inclined rolls 9 are moved along their axis using rods 19 passing through the hollow rolls 17. Rods 19 does not rotate around its axis and is fixed on one side in rotation guide 20 (e.g. ball bearing), the other side of rods 19 is a pneumatic or hydraulic piston 21. In the same way, rods 19 are pneumatic or and 21 is carried out along the movement axis, thus moving the inclined rolls 9 mounted through guides 20 of rotation with rods 19.

The mechanism for moving flat and curved glasses in quenching and cooling positions, the value (Fig. 3) is a roller conveyor consisting of a series of horizon rolls rotating around its axis in each of the guides at an angle of 10-45 located a pair of kinematically connected inclined rolls 9. The transfer of torque to the hollow rollers 17 and rollers 1.4 is carried out by chain transmission 16 and sprockets 15, and to the mountains: the horizontal rollers through two double hinge Hook 12. Hollow 17 and horizontal 7 rolls in contact with glass you are heat insulating sheath.

The installation works as follows.

A flat sheet of glass from the heating furnace 1 enters the rollers 22 into the pressing mechanism 2. In this case, the inclined rolls 9 are in the position shown by the dotted line, i.e. most distant from glass. At the moment when the glass rises between the contour split matrix 5 and continuous. punch 6, rolls mechanism 3 pre-. they spin their rotation, the glass stops and with the help of special

The mechanisms (not shown) are set in the desired position for molding. The resolution of the matrix 5, the split forming contour of which is found by Hook 12, roll 14; sprockets 15 and chains 55, is somewhat lower than forming a horizontal gear 16 on hollow rolls 17, on which are covered with these rolls (for example, pullets) of the covering rolls 7, A sheet of glass 18 begins to rise, capturing with its forming contour.

A flat sheet of glass from the heating furnace 1 enters the rollers 22 into the pressing mechanism 2. In this case, the inclined rolls 9 are in the position shown by the dotted line, i.e. most distant from glass. At the moment when the glass rises between the contour split matrix 5 and continuous. punch 6, rolls mechanism 3 pre-. they spin their rotation, the glass stops and with the help of special

The mechanisms (not shown) are set in the desired position for molding. The resolution of the matrix 5, the split molding contour of which finds the dummy rolls 7, begins to rise outward, capturing a sheet of glass 18 with its shaping contour. As in

The forming contour of the matrix 5 has - cuts for horizontal rolls, then the contour of the matrix 5 rises unhindered above the forming horizontal rolls 7 - until the upper surface of the glass touches the surface of the punch 6. The glass thus takes the form of a punch. As soon as the glass 18 is contoured up to the punch 6 by the contour of the matrix 5, the inclined rolls 9 from the pneumatic or hydraulic actuator 21 move along their axis to the position as shown in FIG. 2, being mounted under the glass 18. After the molding, the matrix 5, supporting the molded glass 18 with its contour, is lowered to the lower position. When the matrix 5 is lowered to the lower position, the glass is set on the forming horizontal 7.pumps and inclined 9 rollers of the transfer mechanism 3, and the contour of the matrix 5 is lowered to its original position.

- The rollers of the transfer mechanism 3, starting to rotate, transport the glass to the hardening and cooling device 4.

Inclined rolls 9 are located at an angle of 10-45 to the horizontal roll 7 for the following reasons: at the corners

less than 10 °, the glass has practically a flat shape; at angles greater than 45, the pressure of the glass is largely carried out on the horizontal roller, which is unacceptable, since prints can appear on the glass.

In the proposed design of the movement mechanism, the number of Hook double hinges is halved, the number of pneumatic or hydraulic actuators is three times, the number of hinged supports is three times. In this connection, the cost of manufacturing such a mechanism is reduced, the maintenance is simplified and the reliability is improved.

The economic effect from the implementation of the proposed mechanism for moving flat and curved glass sheets in an installation for horizontal pressing and tempering of sheet glass with a capacity of 400 thousand m of bent tempered glass per year will be 105 thousand rubles. by reducing the cost of this mechanism, increasing reliability in operation and, consequently, more rarely replacing the above parts, fewer emergencies and fewer defects in work.
