A variable cross-section curved half-pipe electrolytic machining tool

Abstract

The invention discloses an electrolytic machining tool of a variable cross-section bent half tube. The electrolytic machining tool comprises a workpiece clamp and a tool clamp. In the tool clamp, a workpiece (4) is supported by a large-end template (3) and a small-end template (7), and the correct position of the workpiece (4) is determined by a locating block (19); the workpiece (4) is compressed on the supporting face of a large-end stand column (15) and the supporting face of a small-end stand column (8) through a large-end pressing block (14) and a small-end pressing block (5); the large-end stand column and the small-end stand column are arranged between an upper fan disc (6) and a lower fan disc (11), and rotating among the large-end stand column, the small-end stand column and a base (9) is achieved through a mandril (12); and the base (9) serves as a clamp body of the workpiece clamp and is connected with a machine tool table. In the tool clamp, a tool cathode (2) is arranged on a connecting plate (1) through a locating mandril (16) and a key (17), and the connecting plate (1) is connected to the machine tool table. The electrolytic machining tool of the variable cross-section bent half tube is convenient to operate, high in production efficiency and high in corrosion resistance.

Description

technical field [0001] The invention relates to an electrolytic machining tool for a variable-section curved half-pipe made of high-temperature alloy. Background technique [0002] The surface of the curved semi-pipe with variable cross-section is irregular, and the material is a high-temperature alloy. The traditional cutting method is difficult to process this part. As a special processing method, electrolytic machining has significant advantages in processing difficult-to-machine materials, complex shapes or thin-walled parts, and is widely used in aviation, aerospace, nuclear energy and weapon industries. The electrolytic machining process requires the workpiece to be easily clamped, precisely positioned, the anode and cathode to conduct electricity conveniently, and the materials used must be corrosion-resistant. Therefore, the reasonable design of the tooling has an important impact on ensuring the machining accuracy and surface quality of the workpiece. Contents of ...
