DE893621C - Shaping of glass objects for the purpose of grinding and polishing with grinding devices - Google Patents

Description

The subject of the experience is a. Shaping of glass objects to hold @ the same during machine grinding and polishing.

Up until now it was customary to use glass objects for refinement, such as grinding and polishing, only by hand or in various bell elves, with or without these to keep. But since there is no bar time for the designated objects (glass prisms) a corresponding benefit can be expected, because in addition to quality only a lower (price can still secure a. sales., it is from Economic status is required from the manual work by machine To replace work.

During the manufacture of the glass body! When pressed, arise on the glass body B @ rocking @ changes, which has the consequence that irregularities at the insertion points arise that prevent the vitreous from turning exactly in the correct position can.

According to the invention, @ da'her turn bugs. attached, the stop surfaces form so @ that the glass body is precisely positioned with the help of these stop surfaces can be clamped.

In the drawing there is an object intended for grinding Example of a glass prism for chandelier hangings illustrated.

When pressing or casting the züz grinding glass body, here the Prism i, remain on the same chunk of the 9, which is an accurate machine Very hindering sanding; to clamp such glial objects perfectly into the to be able to, i apply the vitreous glue pressing or casting with two or more Provided with warts 2 and at the other end with a cafibrated approach 3. With q. is the hole for hanging the prism! The warts and the neck are cut out in the relevant manufacturing forms.

The grinding device is then equipped with the corresponding fitting pieces 5 provided, in their bores correspondingly shaped hard rubber inserts or @dfgl. elastic inserts 6 are provided in which the warts 2 fit tightly. At the other end of the prism is on the calibrated approach. 3 the bracket 7 made of metal with a fully sealed elastic insert. As a support for the bracket 7 is a support bracket B.

"The brackets 2, which are referred to as warts, can have various shapes have e.g. B. a prism or truncated cone shape. The approach 3 can be a four or Hexagonal or truncated cone shape obtained in order to clamp the glass object in corresponding 'holders on the grinding machine that are not subject to protection are to be suitable.

The attachment of the brackets 2 and 3, which are shaped as always, to the Object i enables quick and absolutely safe clamping of the object to be ground Gl.ase object in a semi or fully automatic way, because the warts 2 and the approach 3 offer rigid attack surfaces for the holding members 5 and 7, the grinding device. The device enables grinding according to the required pitches and angles, for hollow and flat grinding when grinding and polishing without re-clamping, as well as the absolutely precise and quickest loading of the devices.

Like a solid object, a hollow glass body can be similar Be well equipped to hold it securely when grinding and polishing.

By attaching the warts: 2 and 3 is a machine grinding and polishing without the use of specially trained workers at significant levels It is possible to increase the productivity of a worker.

Claims (2)

PATENT CLAIMS: i. Shaping to hold glass objects at Grinding and polishing, characterized in that the objects! During manufacture in the die or mold at one end of the surface with two or more lugs (2) and at the opposite end with a conical or conical shoulder (3) are provided. 2. Shaping according to claim i, characterized. marked, cdass the warts (2) and dfer approach (3) have different stereometric shapes.
