SU743955A1 - Sheet glass bending device - Google Patents

Description

flat glass and improved product quality.

This is achieved by the fact that in a device for bending sheet glass containing a non-profiled convex shape, a bending mechanism comprising a pressing frame made in the form of two profiled ilastins joined by flexible tapes and the latter is made in the form of a drive shaft located under the shape connected by flexible bodies with clamping frame edges.

ha fig. 1 shows schematically the device, a general view; in fig. 2 - nrnmnia frame and shaft with drive, top view.

Sheet 1 glass together with a clamping frame consisting of iron plates 2, made, for example, from heat resistant steel with thickness 3 - /; 0 mm, hard steel 5-10U mm, and with them flexible leite 3, made from nickel with thickness 0.05 -il, 0 mm, shirppoy 5-100 mm, laid pa convex shaped form 4, which ustapovlepa pas trolley (PA fig. not shown). The device provides the ability to lay on the form of several sheets of glass, naimer four. Ball 5, made of heat-resistant steel with a diameter of 10-100 mm, holding a drive 6 for its rotation, is iodine form n connected to the profiled plates with a gpb cable /, made of PNHR wire at two points L p 13, located along the center of the wire, and in 1 point With shaft with lead. It is preferable to connect the plates with the shaft at four points, for example, along the edges of the plates and at the two points of the shaft with the drive (not shown). A flexible cable connecting the power and shaft with a drive, depending on the radius of curvature of the jib of the form, can pass through the edges of the shape of the holes cut out for this target or iodine (see fig. And shown). The shaft drive is mechanical, and it can also be handy, which is necessary to select the optimum mode of operation of the device and the transition to different options for the thickness and number of bendable glass.

When the shaft is rotated manually or mechanically, clockwise, the flexible cable is wound on it and exerts an adjustable pressure on the bending glass sheet through the profiled plates of the clamping frame. The profiled plates press the bendable sheet of glass to the form along its forming, and the flexible mites press it along the end edges of the form.

The use of a clamping frame with profiled lamellas allows you to bend glass or several glasses at the same time as with central cylindrical and complex curvature along, j; pxiiocTH. The device allows to bend cieKJia with a deflection greater than the radius of curvature of the given shape, which, when used, is constant.

load pa glass. The use of adjustable pressure allows the glass to be bent at the temperature of the glass tempered glass softening temperature and, thus, to obtain glass with the preservation of high quality nx

surface. The device can be easily FROM from; 1 it is more case in operation. The use of adjustable pressure-1I for bending glass lnst does not increase it as

fit the glass to the form and thereby increase the speed of bending, significantly newer operation of the device, especially when using kruipogaiapiriHbix glasses with a radius of curvature of 11 BIG forecast arrow.

For example, the bending of four glasses of julified glass with a thickness of 6 mm with chi; the curvature of the upper curb, radius of m ZOO mm;

for the generators mnn them being simultaneously bent using an up-to-date device is carried out for 4– iMHii against 1.0–1.2 h at sgiopppp with ps using

cTCK.ia. Glasses made with the help of the proposed device are distinguished by high quality, high quality and a better fit to the given shape of the surface. At etol, the gap between the neat glasses does not exceed 0.3 mm.
