Abstract
The invention relates to the field of machining tool manufacturing, in particular to an arc rear angle forming blade machining method. The arc rear angle forming blade machining method comprises the following steps: (1) a blade is machined into an annular column body of which three arcs are connected together along the radial direction; (2) the blade is treated to reach set hardness through thermal treatment; (3) a curved surface is polished, wherein the polishing operation only changes the roughness of the blade without changing the shape and size of the blade; (4) the blade is subjected to linear cutting to form three chip accommodating grooves with front surfaces respectively; (5) the front surfaces are ground. According to the arc rear angle forming blade machining method provided by the invention, the grinding to the rear surfaces of arc curves is omitted (the operation is troublesome, and the cost is high); the polishing operation is added (the surface of the part is the annular column body formed by the three arcs connected together, so the polishing operation is very easy); the linear cutting is also easy to operate, therefore, the manufacturing technique for the blade is greatly simplified, the machining cost is reduced, and the machining efficiency on the blade is improved.
Description
Technical field
The present invention relates to machining tool and manufacture field, particularly relate to a kind of circular arc relief angle forming-tool slice processing method.
Background technology
In mechanical processing process, often can run into the situation with circular arc relief angle shaping blade processing parts, if the vital part pull bar (as shown in Figure 1) in primary cut-out is exactly need the part with the processing of circular arc relief angle shaping blade, its form of thread is R circular arc, major diameter of thread and footpath, end tolerance grade require very high again, therefore band circular arc relief angle formed machining blade must be adopted, i.e. circular arc relief angle shaping blade, as shown in Figure 2, circular arc relief angle shaping blade comprises 101 and 102 above below, wherein, 101 is plane, next 102 are made up of three arc surfaces connected along blade radial direction.
Because circular arc relief angle shaping blade is below circular arc camber, the effect of blade relief reduces the contact area (thus reducing cutting force) with part to be processed after cutter, after blade, the quality of roughness directly affects the quality on part to be processed surface, therefore require that cutter will have the roughness required again of overall size accurately below, hardness in addition due to blade is very high again, therefore existing processing method adopts profile grinder grinding or uses numerically control grinder grinding, its processing method is as shown in Figure 3: blade is processed into the ring cylinder that three circular arcs connect and reprocesses out three bands chip pocket above by (1), (2) heat treatment: quenching (making cutter reach certain degree of hardness), (3) to after circular arc and carry out grinding above and (reach certain roughness, adopt profile grinder grinding or use numerically control grinder grinding).
Owing to having used profile grinder grinding or numerically control grinder grinding in above-mentioned processing method, therefore there is complex process, problem that production cost is high.
Summary of the invention
The object of the present invention is to provide a kind of circular arc relief angle forming-tool slice processing method, to simplify the processing technology of circular arc relief angle shaping blade, to reduce the manufacturing cost of circular arc relief angle shaping blade.
In order to solve the problem, circular arc relief angle forming-tool slice processing method of the present invention is by the following technical solutions: circular arc relief angle forming-tool slice processing method, comprises the following steps: it is the ring cylinder that three circular arcs radially connect that blade is processed into outer peripheral face by (1); (2) heat treatment: make blade reach setting hardness; (3) carry out polishing to curved surface, polishing only changes the roughness of blade, does not change the shape and size of blade; (4) Linear cut: process three bands chip pocket above; (5) before grinding.
Step refers to Quenching Treatment to the heat treatment of circular cylinder in (2).
Because circular arc relief angle forming-tool slice processing method of the present invention eliminates the grinding (troublesome poeration, cost is high) after circular curve, add polishing (piece surface is the ring cylinder that three circular arcs connect, so polishing operation is very easy to); Linear cut operation, also than being easier to, therefore significantly simplify the manufacturing process to blade, decreasing processing cost, improve the working (machining) efficiency to blade.

Detailed description of the invention
The embodiment of circular arc relief angle forming-tool slice processing method, as shown in Figure 5, this comprises the following steps: it is the ring cylinder that three circular arcs radially connect that blade is processed into outer peripheral face by (1); (2) heat treatment: make blade reach setting hardness, in this step, refers to Quenching Treatment to the heat treatment of circular cylinder; (3) carry out polishing to outer peripheral face, polishing only changes the roughness of blade, does not change the shape and size of blade; (4) Linear cut: process three bands chip pocket above; (5) before grinding.
