CZ20601U1 - Electroerosion wire cutter for turbine and aircraft industries - Google Patents

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

Technical field

The technical solution relates to an electroerosive wire cutter for the turbine and aerospace industries operating in six-axis mode.

BACKGROUND OF THE INVENTION

Until now, electroerosion cutters for the turbine and aerospace industry, for various electroerosive cutting fields, have been designed in such a way that the machine operates in a maximum of six axes mode where the operator has to change the workpiece position and remove the cut waste or otherwise to the collision of the machine with the cut waste. Furthermore, the operator must check and modify each machining operation. This considerably increases the cost of the entire machining process, as labor productivity is low.

The essence of the technical solution

These drawbacks are eliminated by an electroerosive wire cutter for the turbine and aerospace industry, according to the present invention, which consists in providing a space in the cutter base over which the lower arm and the upper arm are located and in the base body there is a retractable support arm. On the upper arm there is an element for displacing the cut waste.

The electroerosive wire cutter for the turbine and aerospace industry according to this technical solution has the greatest advantage in that the cutting process proceeds automatically even after the cutting, when the cut waste is knocked into the free space. The cutting process automatically repeats without any problems without the participation of the operator, who only removes accumulated cut waste from the area where he attacked for a certain time.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a schematic arrangement of the individual arms above the free space, and FIG. 2 shows the extended support arm below the inter-ring ring, above which the cut-out element is displaced.

Examples of technical solutions

The electroerosion wire cutter for the turbine and aerospace industry of FIG. 1 consists of a pedestal 1 into which a cut-out space 2 is formed. Above the space 1 there is a movable lower arm 3 and a movable upper arm 5. On the upper arm 5 there is an element 6 for displacing the cut waste. A retractable support arm 4 is mounted on the side of the base body 1.

The electroerosive wire cutter for the turbine and aerospace industries works by placing the intermediate ring between the holding rollers, setting the cutting program and starting the machine. The movable upper arm 5, together with the lower arm 3, moves above the ring ring and the cutting process begins. After cutting the shape for inserting the turbine blade, the cut waste remains hanging on the hair. Then, both arms 3 and 5 are displaced and a support arm 4 extends below the intermediate ring 4. Above the cut waste, the waste displacement element 6 moves and the movement of the element 6 downwards displaces waste into space 2. The next shape cutting process for the turbine blade to cut the last shape for the turbine blade. Then the machine automatically stops, the inter-ring with the cut-out holes for the turbine blades is released from the holding rollers and removed out. The amount of waste cut out is checked and removed from space 2 if necessary and the cutting process is repeated after inserting another intermediate ring.

Claims (1)
