Abstract
The utility model discloses a race broach group formed by combining a rough race deep broach, a rough race toothed wide broach, a finishing race tooth top-surface broach, a finishing race shoulder surface broach and a finishing race toothed broach. The race broach group has the advantages of convenience in combination, simple broaching process, long service life, low processing cost, high production efficiency, and the like, can replace the traditional race milling processing through the race broaching processing mode and is especially applicable to the processing of a wheel disc of a steam turbine.
Description
Technical field
The utility model relates to the race broaching tool group that a kind of processing vapor turbine wheel roulette groove is used.
Background technology
Steam turbine is the high accuracy electronic product of collection high temperature, a high pressure, high speed one, and is its core as the rotor of steam turbine, and multistage wheel disc is the chief component of rotor.The quality of wheel disc race processing will directly influence exerting oneself of steam turbine and vibration situation.At present the special plane Milling Process is adopted in the processing of race substantially both at home and abroad, form by roughing milling cutter, half finish-milling cutter, the milling successively of finish-milling cutter.Because the race working depth is darker, the Tool in Cutting amount is big, and cutting load is big, and tool wear is fast, and the turbine rotor material is heat-resistance stainless steel, the intensity height, and cutting ability is poor, cut several times, and working (machining) efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of high accuracy, high efficiency, low cost, long-life race broaching tool group, utilizes it to replace traditional race Milling Process by the mode of race broaching processing.
For solving the problems of the technologies described above, the utility model race broaching tool group is combined by rough race deep-draw cutter, the wide broaching tool of rough race profile of tooth, finish draw race crest top land broaching tool, finish draw race omoplate surface broach and finish draw race profile of tooth broaching tool.
Above-mentioned race broaching tool group is provided with the V-type groove on the right side of described each broaching tool.
Above-mentioned race broaching tool group, described rough race deep-draw cutter and the wide broaching tool of rough race profile of tooth respectively have 12.
Above-mentioned race broaching tool group, described rough race deep-draw cutter comprises rough race deep-draw cutter one and rough race deep-draw cutter two each six, the wide broaching tool of described rough race profile of tooth comprises the wide broaching tool of the wide broaching tool one of rough race profile of tooth and rough race profile of tooth two each six, and the shape of described finish draw race profile of tooth broaching tool is identical with the line style of described race.
The utility model is owing to adopted above-mentioned technical pattern, and what its employing independently separated forms the broaching tool group to broaching tool more than five kinds, successively workpiece is processed successively.The broaching tool combined and instant, Broaching Technology is simple, long service life, processing cost is low, the production efficiency height.It replaces traditional race Milling Process by the mode of race broaching processing, is the advanced cutter of steam turbine wheel disc processing.The utility model broaching tool group is fit to the race processing of plate-like wheel disc, and the race of processing is complex-shaped, the profile accuracy height.Can on the broaching machine of special use, use race broaching efficient height; Good economical benefit, but the broaching tool reconditioning is repeatedly used.

The specific embodiment
As shown in the figure, the utility model race broaching tool group is combined broaching tool more than five kinds by rough race deep-draw cutter 1 and rough race deep-draw cutter 22, the wide broaching tool 1 of rough race profile of tooth and the wide broaching tool 1 of rough race profile of tooth, finish draw race crest top land broaching tool 5, finish draw race omoplate surface broach 6, finish draw race profile of tooth broaching tool 7 etc.As shown in figure 11, the same with finish draw race profile of tooth broaching tool 7, the right side of each broaching tool is provided with the V-type groove, is fixed on by V-type briquetting 8 on the broaching tool knife rest 9 of lathe.Every the shape of broaching tool and its in the broaching process of processing vapor turbine wheel roulette groove respectively shown in corresponding each figure.Rough race deep-draw cutter 1 six broaching tool to workpiece three cuttves of broaching, the mutual alignment that motion by lathe changes workpiece and broaching tool obtains the surplus of required broaching, be that six of rough race deep-draw cutter 1 is broached broaching tool behind first cutter, workpiece and broaching tool are thrown off, the broaching tool backhaul, workpiece moves to broaching tool, rough race deep-draw cutter 1 six the distance of total broaching amount of broaching tool as second cutter broaching surplus, rough race deep-draw cutter 1 six broaching tool second cutter of broaching, workpiece and broaching tool were thrown off after the broaching of second cutter was finished, the broaching tool backhaul, workpiece moves to broaching tool, rough race deep-draw cutter 1 six the distance of total broaching amount of broaching tool as the 3rd cutter broaching surplus, six of rough race deep-draw cutter 1 is broached broaching tool behind the 3rd cutter, obtains shape as shown in Figure 2.After six of rough race deep-draw cutter 1 is finished broaching tool the 3rd cutter broaching, tool changing is broached broaching tool with six of rough race deep-draw cutter 22, six the same with rough race deep-draw cutter 1 the broaching tool broaching layout, rough race deep-draw cutter 22 six broaching tool to the workpiece four blade of broaching, obtain shape as shown in Figure 3.Behind rough race deep-draw cutter one 1 broaching three cuttves and the rough race deep-draw cutter 22 broaching four blades, obtain shape as shown in Figure 4.Tool changing with the wide broaching tool 1 of rough race profile of tooth six to workpiece broaching once broaching tool, obtain shape as shown in Figure 5, tool changing with the wide broaching tool 24 of rough race profile of tooth six to workpiece broaching once broaching tool, obtain shape as shown in Figure 6, tool changing with finish draw race crest top land broaching tool 5, finish draw race omoplate surface broach 6 and 7 pairs of workpiece broachings of finish draw race profile of tooth broaching tool once, obtain shape as shown in Figure 7, as Fig. 8, Fig. 9, Figure 10 and shown in Figure 11, the shape of finish draw race profile of tooth broaching tool 7 is identical with the line style of race.
