METHOD AND BLANK FOR MANUFACTURING A COMPRESSOR BLOCK OF A SMALL-TYPE REFRIGERATION APPLIANCE, PARTICULARLY FOR A HERMETICALLY ENCLOSED REFRIGERANT COMPRESSOR ARRANGEMENT
The invention concerns a method and a blank ( 30 ) for manufacturing a compressor block of a small-type refrigeration appliance, particularly for a hermetically enclosed refrigerant compressor arrangement, the blank comprising a handling section ( 34 ) and at least two working areas ( 43, 46 ). The blank ( 30 ) is clamped in a working arrangement at a handling section ( 34 ), the blank being worked during maintenance of the clamping. It is endeavoured to reduce the dimensions of a compressor block, though maintaining the opportunity of performing several working steps during one clamping process. For this purpose, it is provided that the handling section ( 34 ) is removed after the working.
1 . A method for manufacturing a compressor block of a small-type refrigeration appliance, particularly for a hermetically enclosed refrigerant compressor arrangement, in which a blank is used, the blank being clamped in a working arrangement at a handling section, the blank being worked at least two different working areas during maintenance of the clamping, wherein the handling section is removed after the working.
2 . The method according to claim 1 , wherein the handling section is formed during manufacturing of the blank.
3 . The method according to claim 2 , wherein a predetermined breaking point is provided at the handling section.
4 . The method according to claim 3 , wherein the handling section is knocked or broken off.
5 . The method according to claim 3 , wherein the predetermined breaking point is made as a notch.
6 . The method according to claim 3 , wherein the predetermined breaking point is made when manufacturing the blank.
7 . The method according claim 1 , wherein the handling section is made at an edge area of the compressor block.
8 . The method according to claim 7 , wherein the edge area has a maximum distance from areas of the compressor block, which are critical with regard to manufacturing tolerances.
9 . The method according to claim 1 , wherein the handling area is permitted to project radially in relation to a bearing bore for a crankshaft.
10 . The method according to claim 1 , wherein the handling section is located in parallel to an axis of a cylinder.
11 . A blank for manufacturing a compressor block of a small-type refrigeration appliance, particularly for a hermetically enclosed refrigerant compressor arrangement, with a handling section and at least two working areas, wherein the handling section can be separated from the compressor block.
12 . The blank according to claim 11 , wherein a predetermined breaking point is located between the compressor block and the handling section.
13 . The blank according to claim 11 , wherein the handling section has a maximum distance from an area of the compressor block, which is critical with regard to manufacturing tolerances.
14 . The blank according to claim 11 , wherein the handling section extends radially in relation to a bearing bore for a crankshaft.
15 . The blank according to claim 11 , wherein the handling section is aligned in parallel to an axis of a cylinder.
