[0002] Gas turbine is a strategic industry related to national energy and national defense security. It is the highest-end product in the field of energy power equipment and represents the highest level of equipment manufacturing industry; the "connector fixing ring" is an important part of the H100-110 nozzle diffuser One, it is characterized by thin wall thickness, special material, easy deformation, complex structure, and because the upper end surface of the part is a circular arc surface, the lower end has no stable support, which makes it difficult to clamp and cannot be fixed
The wall thickness of the main body of the part is only 6mm stainless steel sheet. When processing part of the size, the workpiece will deform along with the cutting edge, so that the workpiece cannot meet the requirements of the drawing; the welding groove of the original design of the diffuser will cause the L-shaped groove to remain Go down the steps, because in the groove, the tool cannot be inserted and manual grinding cannot be performed later
For details, see figure 1 , the layout of the original welding groove of the pipe fixing ring, there is a certain risk in this design, that is, during tailor welding, the flux will flow to the inner groove of the groove, and there will be residual flux attached to the L-shaped groove. The entrance of the groove is collinear, and the residual flux cannot be removed by the tool processed in the later stage, and the groove is narrow and deep, and it cannot be manually polished

Embodiment Construction
[0045] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0046] see Figure 1-13 , gas turbine takeover diffuser takeover fixed ring combination processing technology, it includes the following steps:
[0047] Step 1: Workpiece splitting;
[0048] The specific operation process of workpiece disassembly is to divide the entire standard connecting ring 1 along the L-shaped notch 2 and the groove weld 4 into the part body 6 and the welded part 5 .
[0049] Wherein, the distance A deviates between the groove weld 4 and the inner side wall of the L-shaped notch 2 on the part body 6 ;
[0050]The reason for splitting the workpiece is that according to the requirements of the original drawing, there is a certain risk in this design, that is, during tailor welding, the flux will flow to the inner groove of the groove close to the L-shaped notch 2, and there will be residual flux attached In the L-groove, since the ...

The invention provides a combination machining process for a connecting pipe fixing ring of a connecting pipe diffuser of a gas turbine. The combination machining process comprises the steps that firstly, a workpiece is split; secondly, a blank piece split in the step (1) is blanked; thirdly, the blank piece is primarily machined, and a machining amount is reserved for the blank piece; fourthly, a connecting pipe fixing ring machining tool is manufactured, and the to-be-machined blank piece and the connecting pipe fixing ring machining tool are fixed; fifthly, a part body machined in the fourth step and the welding part blank piece are subjected to tailor welding; sixthly, a tool used for machining an L-shaped notch is manufactured; seventhly, a cutter is adopted for machining the L-shaped notch; and eighthly, after the whole connecting pipe fixing ring is machined, the connecting pipe fixing ring machining tool is dismantled. By manufacturing the clamping tool, modifying a welding process, manufacturing the special cutter and adopting a dispersing-recombining machining mode, the machining problem of the fixing ring is solved.
Description
technical field [0001] The invention relates to a combination processing technology of a gas turbine nozzle diffuser nozzle fixed ring, and belongs to the field of cardboard production equipment.
