Embodiment Construction

[0032] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0033] Such as Figure 1 to Figure 8 As shown, a rotary open tooling for electrolytic forming of integral blisks includes a sleeve assembly 3. One end of the sleeve assembly 3 is connected to the cavity 2 on the left side of the machine tool through a pin and a screw. A machine tool open shaft 1 is coaxially sleeved, and the machine tool open shaft 1 extends to the inner cavity of the sleeve assembly 3. The inner cavity of the sleeve assembly 3 is coaxially installed with a shaft holder 10, and one end of the shaft holder 10 is connected to the machine tool. The inner hole of the open shaft 1 is matched. The other end of the shaft holder 10 is provided with a curved sliding track 12 arranged symmetrically with respect to the axis. The arc tops of the two curved sliding tracks 12 face oppositely, and the curve of the curved sliding track 12 The trajectory is det...

Abstract

The invention discloses a blisk electrolytic forming rotary open type tool and an electrolytic forming method. The blisk electrolytic forming rotary open type tool comprises a sleeve assembly, a sleeve cover plate, an electrolyte water inlet pipe, an electrolyte water port, a power connection screw rod, a tool setting pin, an electrode plate, a shaft holder, a rotary connecting piece and a curve type sliding rail. A blisk electrolytic forming method comprises the following steps of step 1, installing a rotary open type tool on a machine tool open type shaft and a left cavity of a machine tool;step 2, determining initial machining original points of the machine tool open type shaft and X, Y and Z axes of a workbench of a horizontal electrolytic machine tool; step 3, inputting machining parameters through a control panel of the horizontal electrolytic machine tool; step 4, processing a single blade in a blisk; and step 5, after a single blade of the blisk is opened, adjusting an angularposition of the blisk through a blisk indexing tool, and processing a next blade till that machining is completed. The tool is used for carrying out rotary opening machining on a variable-curved-surface blade of the blisk, and the machined blade is uniform in allowance and high in precision.

Description

Technical field [0001] The invention belongs to the technical field of electrolytic machining, and in particular relates to a rotary opening tool for electrolytic forming of an integral leaf disc and an electrolytic forming method. Background technique [0002] Motor processing is a process that uses the principle of electrochemical anode dissolution to remove materials and finally process parts into shapes. This technology is not limited by the mechanical and mechanical properties of the workpiece material, and the surface processing quality of its parts is high, stress-free, no heat-affected zone, and no loss of tool cathode. With the development of science and technology and industrial technology, new requirements are put forward for the form and scale of parts, and products are developing towards precision and miniaturization. Compared with non-integral blisks, the new type of aero-engine compressor blisk has the advantages of smaller weight and higher stability, and has bro...
