Process method for improving rigidity of large titanium alloy ring groove thin-wall part

Abstract

The invention discloses a process method for improving rigidity of a large titanium alloy ring groove thin-wall part. The process method includes the steps: (1) roughly machining the overall dimension of a ring groove of the part, precisely machining the internal dimension of the ring groove to meet design requirements, and heating low-melting-point alloy to a molten state; (2) uniformly filling the part to a preset depth; (3) waiting for sufficient cooling of the low-melting-point alloy; (4) inspecting whether the appearance of the part has pouring defects or not; and (5) subsequently machining the part when not detecting abnormal change of the overall dimension of the part. The process method has the advantages that by the aid of auxiliary reinforcement of the low-melting-point alloy, the system rigidity of a workpiece is improved, machining stability of the part is realized, the technical problems of machining deformation, ultra-poor dimension accuracy and the like in the machining process of the large ring groove thin-wall part are solved, the machining quality and the machining efficiency of the part are effectively improved, and the rejection rate of deep groove ring type and deep cavity shell type thin-wall parts in the machining process is reduced, and the process method has a wide application prospect.

Description

technical field [0001] The invention relates to a process method for improving the rigidity of a titanium alloy large annular groove thin-walled part, which belongs to the technical field of mechanical processing. Background technique [0002] During the processing of various large and medium-sized ring groove thin-walled parts, due to the poor workmanship of the parts, cutting vibration and processing deformation are very easy to occur. It is difficult to guarantee the dimensional accuracy of the parts by conventional processing methods. The existing technology generally uses paraffin, rosin, and gypsum reinforcement to enhance the rigidity of the workpiece and realize the stability of the processing of large ring groove thin-walled parts. The method is to use paraffin as a filler and pour it into the part groove. After the paraffin solidifies, the paraffin and There is a gap of 0.1-0.2mm between the groove walls, but its adhesion is not good, and the rigidity of the part s...
