Description

one

The invention relates to installations for liquid tempering glassware.

The known devices containing a hardening furnace, a hardening bath and a loading mechanism do not provide the required quality of the hardened products.

In the proposed installation, the quenching bath is mounted on the same carriage with the furnace floor with the possibility of moving in the horizontal direction from the drive.

This allows improving the quality of the manufactured products and improving the working conditions.

Figures 1, 2, and 3 show a longitudinal section of the installation in the following positions: heating the product in the furnace, loading and unloading the products, respectively.

The proposed installation has a quenching furnace I of cylindrical form with heaters and channels of masonry, ekpan 3 of stainless steel things and rolling back under I

4, quenching bath 5 with a mesh basket 6 equipped with a lever mechanism 7 and an electric heater 8 equipped with a hood 9 5 and a collector 10 dd of carbon dioxide supply and mounted on one carriage II with a hearth 4 furnace I. - Loading mechanism mounted on frame 12 the furnace roof I and representing m-angu 13 with suspension 14, on which one or several platforms 15 for installing products 16 are placed.

The installation works as follows.

By means of the actuator 17, under 4 is lowered to the lowest position, then through the actuator 18, the movement of the carriage II under 4 retracts,) to the left, and quenching, the bath 5 stops to the right of the furnace I,

The stove I is open for loading. The chain pi 19, on which the suspension 14 hangs, is driven by the actuator 20.

Suspension 14 is released to the lowest position and the products 16 are placed on pads 15 by means of tongs (see Fig. 2}. Then the products} 16 are lifted into the furnace I and set at the right height. Under 4 it is centered with the furnace I and raised to the the upper position, and the quenching bath 5 is installed under the extracting SIXTURE 9. At the same time, the knife 21 of the furnace I enters the groove of the hearth 4 filled with asbestos cord and closes it from the bottom. In this position, the products are heated (see fig.), while temperature measurement in the upper and lower zones of the furnace is carried out by ter oparami 22 and 23. To drop the products 16 in, the bath 5, the fork 24 of the cable of the cable 25 with the handle 26 is put into the working position, the rod 13 is lowered and the bearing pin 27 sits on the fork 24, and the suspension 14 continues to descend, thereby moving the lever 28 and thereby turning the platforms 15 with the parts 16. The products 16 are brought into the bath 5, which, when the hearth 4 moves to the leftmost position, is installed under the open furnace I (see figure 3). 4 7 (MBo 1 | zb, ignition -Sh1I hsdkost in protection 5 i skip carbonic acid. Tevsheratura hardening process is vibrated with a thermocouple 29. After discharging products 16 into bath 5, which is discharged under the hood 9, it is centered with furnace I The reset plug 24 is installed in a neutral position. The mesh basket 6 with six cooled products 16 is lifted out of the quenching tank by means of a lever mechanism 7. From basket 6, the product 1 is pulled, the machine for liquid tempering of glassware containing a tempering furnace, a quench furnace, a quench furnace, a quench furnace, a quench furnace, a quench furnace, a quench furnace and The loading mechanism, which means that, in order to improve the quality of hardened products and improve working conditions, the quenching bath is mounted on the same carriage with the furnace hearth with the possibility of movement in the horizontal direction from the drive.
