Embodiment

[0070] At present, among the models of engines undertaken by the company, there are many cast high-temperature alloy ring parts. Due to the limitation of structure and processing characteristics, the cost of fixtures and tools is relatively high. . The processing and positioning process method of the present invention changes the original part process design idea, greatly improves the processing quality of the parts, reduces the cost of tooling, greatly concentrates the process, reduces non-value-added time such as turnover, improves processing efficiency, and saves more than half of tooling costs. Shorten the processing time by more than 20%.

[0071] A processing and positioning process method for casting high-temperature alloy ring block parts in this embodiment includes the following steps:

[0072] 1. Prepare the wool, which is provided with a craft edge;

[0073] 2. Milling 1 datum plane and 2 datum holes on the process side, the present invention uses the unified benc...

Abstract

The invention discloses a machining and positioning process method for casting high-temperature alloy ring block parts, and belongs to the technical field of aero-engines. The machining and positioning process method for casting the high-temperature alloy ring block parts comprises the following steps that S1, a blank is prepared, and a process edge is arranged on the blank; S2, a positioning reference is planned, and one reference surface and two reference holes are machined in the process edge; S3, fan-shaped surfaces at the two sides of the blank are linearly cut; S4, turning is carried out a revolution surface by adopting a whole-ring group machining manner; S5, outer side laces are milled, and drilling is carried out; and S6, the process edge is cut off through linear cutting. According to the machining and positioning process method for casting the high-temperature alloy ring block parts, the technical problems that the machining and positioning stability of casting the high-temperature alloy ring block parts is poor, the cutter consumption is large, and the machining efficiency is low are effectively solved.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to a processing and positioning process method for casting high-temperature alloy ring block parts. Background technique [0002] During the processing of cast superalloy ring blocks in the manufacture of aero-engines, the structural problems of cast superalloy ring block parts lead to unstable positioning and clamping, which in turn leads to chain problems affecting the processing quality of parts in many aspects such as fixtures, tools and process arrangements. . The problems faced by the processing of existing casting superalloy ring block parts are as follows: [0003] (1) High-temperature alloy ring block parts are generally single straight or conical fan-shaped segments. The parts themselves have no clamping structure (steps, mounting edges, etc.) available for processing. Clamping and other methods, the direction of positioning and fixing does not correspond to the pro...
