本発明は大気温度以下の温度でラック塗装部を研削及び
／又は研磨する方法及び装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for grinding and/or polishing rack coatings at temperatures below atmospheric temperature.
［従来の技術］
ラックの研削及び研磨は研削及び研磨作業自体に関して
既に多様の方法で解決された問題である。BACKGROUND OF THE INVENTION Grinding and polishing racks is a problem that has already been solved in a variety of ways regarding the grinding and polishing operations themselves.

冷室内でラック塗装部の研削を可能になす温度まで冷却
することは公知である。However, grinding and polishing cannot easily be carried out on the types of cavities that have great elasticity at ambient temperatures. Racks of this type are used, for example, for rack coating of parts of synthetic materials, which are increasingly being applied in the automobile industry. This is because the rack for a base layer of such a component of synthetic material must have an even greater elasticity than for a base layer of metal, for example. In order to grind and/or polish even the slightest defect in the elastic rack coating at atmospheric temperatures, the entire component with the rack coating can be ground in a cold room. It is known to cool to a temperature of

［作用］
ガス状の寒冷担持体を利用することによって寒冷は正確
に必要な部分に導かれて能率よく寒冷が伝達されるので
ある。[Function] By using a gaseous cold carrier, the cold is guided precisely to the necessary areas, and the cold is efficiently transmitted.
特に有利な構成に於ては、寒冷ガスとして蒸発された寒

る。しかし、他の寒冷媒体も利用出来る。In a particularly advantageous embodiment, an evaporated cold medium is used as cold gas, which already contains the necessary refrigeration and can be adjusted to different temperatures. In particular, liquid nitrogen and liquid argon are suitable because of their safe handling, inert properties and particularly low temperatures. However, other cryogens can also be used.

冷却されるのである。In a further advantageous variant of the method according to the invention,
The area of the rack coating to be ground and/or polished is shielded from the atmosphere, and the cold gas is introduced into the shield and distributed uniformly within the shield. This makes it possible to cool uniformly and efficiently the desired area of the rack painting area, ensuring that only the required amount of cold gas is consumed, without reservation. Because of the elasticity of the rack coating, which decreases with decreasing temperature, the area to be processed is preferably cooled to a temperature of -30 to -50 DEG C.

従って応力が回避されるのである。The apparatus for carrying out the method of the invention forms an intermediate hollow space when placed over the area to be processed, has an outlet opening for the spent cold gas and is connected to a cold gas supply. It is particularly advantageous to provide a recess forming an outlet opening in the edge of the support which rests on the rack coating. Such a mount forms a suitable shield of the area to be ground and provides efficient cold transmission. By virtue of the notch forming the outlet opening provided in the edge of the carrier to be placed, the surrounding area of the surface that is directly affected by the cold gas is also cooled by coming into contact with the cold gas. As a result, an excessive temperature difference between the area to be ground and the surrounding rack coating area,
Stresses are thus avoided.

。It is particularly advantageous to use the method according to the invention to eliminate rack coating defects in finished rack coatings. This is because the invention replaces the method mentioned at the outset and makes double rack coating unnecessary or makes it possible for the first time to carry out multiple rack coatings.
［実施例］
概略的な添付図面を参照して以下に本発明による方法を
例示的に説明する。EXAMPLES The method according to the invention will be explained by way of example below with reference to the accompanying schematic drawings, in which: FIG.

っている。The accompanying drawings show a mounting body 1 connected to a cold gas supply source 2 . The support 1 consists of a substantially hollow cylindrical base body which is connected by a coupling element 3 to a supply conduit 4 which is connected to a cold gas supply 2. At the open end of the hollow cylindrical base body, at the edge on which the mounting body rests on the surface 5, cutouts 6 are provided, these cutouts
It is designed to allow the cold gas introduced into the mounted mounting body l to flow out, and the cold gas discharged at that time is distributed over the range of the rack coating surrounding the mounting body. It has become.

冷却される。If defective areas of the rack coating, e.g. resistant dust particles, are found on the painted surface of the elastic rack at room temperature,
The method according to the invention can be applied. First the dust particles are removed. A mounting body 11 is placed on the resulting visible defect, and inside this mounting body -
50 to -196℃1 preferably -70 to -150℃
Cold nitrogen having a temperature of 30 to 10 seconds is introduced for a period of 3 to 10 seconds. The coating surface of the rack under the carrier, acted upon by this cold gas, is therefore cooled to a temperature of about -30 to -50'C.
このような温度ではラックは僅かな弾性しか有しないで

を行うことが出来るようになる。In the case of defective areas of the rack coating that can only be removed by grinding, for example in the case of thick rank layers that are not uniform in position and do not have a smooth surface, these defective areas are cooled as described above and subsequently It can be ground by grinding. It is advantageous to spray cold gas during the grinding itself as well, in order to eliminate the frictional heat generated and maintain the grinding ability of the rack coating. By grinding out the defective parts of the rack coating in this way, the component can be further rack coated any number of times.
従って本発明による方法は迅速な、簡単に実施出来る、
経済的な可能性を有する種類のラックを研削及び研磨可
能になすのである。The method according to the invention is therefore quick and easy to implement.
This makes it possible to grind and polish a type of rack that has economic potential.
