Abstract

An electroerosion wire cutter for turbine and aircraft industry with a space (2) in the base unit (1), over the space there is a lower arm (3) and an upper arm (5) and in the base unit body (1) there is an extensible supporting arm (4). Above the upper arm (5) there is an element (6) for pushing out cut-off waste.

Description

Electroerosion wire cutter for turbine and aircraft industry
Technical fields
The invention refers to an electroerosion wire cutter for turbine and aircraft industry, operating in the six-axis mode.
Background arts
So far, there are electroerosion cutters for turbine and aircraft industry for various areas of electroerosion cutting available in such versions that the machine works in the mode of six axes at most, when the operator has to change the position of a work piece and to remove cutoff waste, or in some other way has to ensure that the machine will not collide with the cut-off waste. In addition to that, the operator has to check and adjust each operation of working. This significantly increases the cost of working, for the work productivity is low.
Disclosure of invention
The above-described drawbacks can be eliminated with an electroerosion wire cutter for turbine and aircraft industry according to this invention which is characterised in that it has a space in the cutter base unit, over which there are the lower and the upper arms, and there is a extensible supporting arm in the body of the base unit. On the upper arm, there is an element for pushing out cut-off waste.
The greatest advantage of the electroerosion wire cutter for turbine and aircraft industry as designed according to this invention is that the cutting process runs automatically even after cutting is done, when the cut-off waste is knocked out into a free space. The cutting process is automatically repeated without any problems and without the operator's presence - the operator only from time to time removes collected cut-off waste from the space that it had fallen into.
Brief description of drawings
The invention will be explained in details in the drawing, in which picture 1 shows a schematic design of the individual arms over free space and picture 2 shows the extended supporting arm under the dividing ring, above which there is an element for pushing out cutoff waste. Made for carrying out the invention
As shown in the picture 1 , the electroerosion wire cutter for turbine and aircraft industry is comprised of the base unit I with a space 2 for collecting cut-off waste. Above the space i there is a mobile lower arm 3 and a mobile upper arm 5. On the upper arm 5 there is an element 6 for pushing out cut-off waste. On the side of the base unit body \ there is an extensible supporting arm 4.
The electroerosion wire cutter for turbine and aircraft industry works as follows: the dividing ring is placed between the holding pulleys, then a cutting programme is set and the machine put into operation. The mobile upper arm 5 and the lower arm 3 move over the dividing ring and the cutting process starts. After cutting out a shape for insertion of a turbine blade, the cut out waste remains hanging on a thread. Both arms 3 and 5 are then moved away and the supporting arm 4 is moved out under the dividing ring. The element 6 for pushing out waste is moved over the cut-off waste and the element 6 moves down, so that the waste is pushed into the space 2. The process of cutting another shape for a turbine blade is repeated automatically until the last piece for a turbine blade is cut out. The machine then automatically stops, the dividing ring with cut out holes for turbine blades is released from the holding pulleys and is taken out. The amount of cut-off waste is checked, if necessary, the waste is removed from the space 2, and the cutting process starts again after another dividing ring is inserted.
The applicability of the invention
It is possible to use the solution according to the invention in all areas of working, where automation of working of one unit is required and the work piece needs to be moved manually during the operation with a simultaneous removal of waste during the working process.
