Abstract
The utility model discloses a kind of annular groove cutter processing through hole, comprise knife bar, described knife bar is provided with cutter head, and described cutter head front portion is cutting edge, and on described cutter head, cutting edge rear lower portion is provided with overmoving surface; The cutting edge of the utility model annular groove cutter can stretch into inside workpiece, cuts along Cutting trajectory, a middle block of material can be drawn out, and forms the larger diameter through hole needing processing; So both can greatly enhance productivity, the material in the middle of also having saved out, reduces production cost.
Description
Technical field
The utility model relates to the process technology of diameter through hole, is specifically related to a kind of annular groove cutter processing through hole.
Background technology
At present, the plate part that some thickness are little, when needing to process larger diameter through hole on plate, the processing technology of through hole is first use bit bore, more step by step boring to demand size.This processing mode, not only working (machining) efficiency is lower, and the material in the middle of through hole becomes cutting scrap, causes the waste of material, and production cost improves.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one to improve working (machining) efficiency, and the annular groove cutter of cost-effective processing through hole.
To achieve these goals, the technical solution adopted in the utility model is:
The annular groove cutter of this processing through hole, comprises knife bar, and described knife bar is provided with cutter head, and described cutter head front portion is cutting edge, and on described cutter head, cutting edge rear lower portion is provided with overmoving surface.
Described overmoving surface is cambered surface.
Described knife bar and described cutter head are integral type structure.
Described via depth is less than or equal to 4CM.
Need process the clamping workpiece of through hole on the scroll chuck of lathe, described knife bar is contained on the cutter shaft of lathe.
The utility model has the advantage of: the annular groove cutter of this processing through hole, on cutter head, cutting edge rear lower portion grinds overmoving surface; The cutting edge of such annular groove cutter can stretch into inside workpiece, cuts along Cutting trajectory, a middle block of material can be drawn out, and forms the larger diameter through hole needing processing; So both can greatly enhance productivity, the material in the middle of also having saved out, reduces production cost.

Mark in above-mentioned figure is:
1, cutter head, 2, knife bar, 3, overmoving surface, 4, workpiece, 5, feed route, 6, cutting edge.
Detailed description of the invention
Contrast accompanying drawing below, by the description to optimum embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figures 1 and 2, the annular groove cutter of this processing through hole, comprises knife bar 2, and knife bar 2 is provided with cutter head 1, and cutter head 1 front portion is cutting edge 6, and on cutter head 1, cutting edge 6 rear lower portion is provided with overmoving surface 3.
As shown in Figure 3, existing annular groove cutter, cutter head 1 is cube structure, and cutter head 1 front portion is the cutting edge 6 being with gradient processing annular groove; Add man-hour cutting edge and 6 contact cutting with processing component, cutting edge 6 rear lower portion of cutter head 1 does not contact with processing component, so both can process the annular groove of needs.When machining hole wanted by existing annular groove cutter, because hole cutting depth is comparatively dark, it is inner that cutting edge 6 will stretch into workpiece 4, cutting edge 6 rear lower portion of cutter head 1 cutting edge 6 stretch into workpiece 4 inner time, can play the effect of obstruction, the processing of causing hole cannot realize.
The annular groove cutter of the processing through hole that the utility model provides improves on existing annular groove cutter, and on cutter head 1, cutting edge 6 rear lower portion grinds overmoving surface 3, and overmoving surface 3 is arc surface; The cutting edge 6 of such annular groove cutter can stretch into workpiece 4 inside, cuts, a middle block of material can be drawn out, form the larger diameter through hole needing processing along Cutting trajectory; So both can greatly enhance productivity, the material in the middle of also having saved out, reduces production cost.
Further, overmoving surface 3 is cambered surface, and overmoving surface 3 is worn in cutter head 1 cutting edge 6 rear lower portion; When such annular groove cutter cuts, annular groove cutter moves along Cutting trajectory, and cambered surface is convenient to carrying out smoothly of processing, increases work efficiency.
Knife bar 2 and cutter head 1 are integral type structure.Knife bar 2 and cutter head 1 one-body molded, greatly can improve the structural strength of cutter head 1, and then ensure that the processing in hole is carried out smoothly.
Via depth is less than or equal to 4CM.Via depth is less than or equal to 4CM, ensures that annular groove cutter leading cutting edge mouth 6 has good working effect.
Need process workpiece 4 clamping of through hole on the scroll chuck of lathe, the knife bar 2 of annular groove cutter is contained on the cutter shaft of lathe.Through hole processing is carried out on existing lathe, can reduce production cost by high degree.
The course of work of the annular groove cutter of this processing through hole is as follows: determine the surperficial feed route of the workpiece 4 will processing through hole, clamping workpiece 4 and annular groove cutter, annular groove cutter is moved to cutter cutting edge 6 just to the surperficial feed route of workpiece 4; Workpiece 4 rotates, and annular groove cutter edge is perpendicular to workpiece 4 direction rectilinear motion; Machining is carried out after the cutting edge 6 of annular groove cutter contacts workpiece 4; Overmoving surface 3 is stepped down, and the cutting edge 6 of annular groove cutter stretches into workpiece 4 inside and cuts, until the material in workpiece 4 through hole is cut by complete; Draw out material, return annular groove cutter, namely complete the through hole processing of workpiece 4.
Obvious the utility model specific implementation is not subject to the restrictions described above, as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out, all within protection domain of the present utility model.
