Abstract
The utility model discloses a drilling tool capable of once forming. The drilling tool comprises a tool handle, a tool rod and a forming part, wherein the tool rod is arranged on the tool handle, and the forming part is arranged at the top end of the tool rod and comprises a first blade and a second blade. The second blade is arranged on the tool rod, the first blade is arranged on the second blade, the size of the first blade is smaller than the size of the second blade, and an arc groove is formed in the connecting position of the second blade and the tool rod. The structure of the drilling tool is simple, a blade for drilling a rivet hole is added, a valve seat process in an upper flange process can be completed at a time, secondary clamping caused by tool problems is avoided, the distance precision of the rivet hole and an exhaust hole is guaranteed, a drill bit for drilling the rivet hole is eliminated, tool cost is lowered, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of moulding and bores cutter, and cutter is bored in the moulding that is specifically related to a kind of disposable processing upper flange steam vent and rivet hole.
Background technology
The flow process of the valve seat operation in the upper flange operation of now general manufacturer production is: mill valve seat groove → brill rivet hole → exhaust outlet and rough mill → the exhaust outlet finish-milling, and the upper flange of some machine, the customer requirement valve seat has 2 sections different valve seat grooves of width, and at this time the flow process of valve seat operation just becomes: mill valve seat groove 1 → mill valve seat groove 2 → brill rivet hole → exhaust outlet to rough mill → the exhaust outlet finish-milling.Each station of equipment of the processing upper flange valve seat operation of using can only be adorned 4 cuttves at present, can't satisfy and bore steam vent and rivet hole simultaneously, can only change in other the operation boring rivet hole, will cause the secondary clamping like this, so not only need to increase the time processing operation, the amount of labour strengthens, also need many one the brill cutter, and can not guarantee the range accuracy between rivet hole and the steam vent, efficiency reduces, and cost increases.
The utility model content
The purpose of this utility model is to provide a kind of one-shot forming to bore cutter, has realized the disposable boring of steam vent and rivet hole, enhances productivity, and saves cost.
For realizing this purpose, the utility model has adopted following technical scheme:
Cutter is bored in a kind of one-shot forming, comprise handle of a knife, knife bar and moulding section, described knife bar is located at described handle of a knife, described moulding section is located at described knife bar top, described moulding section comprises first segment blade and the second joint blade, and the described second joint blade is located at described knife bar, and described first segment blade is located at the described second joint blade, described first segment blade size is less than the described second joint blade, and the second joint blade and described knife bar junction are provided with arc groove.
Further, described first segment blade is for boring the rivet hole blade.
Further, the described second joint blade is for boring the steam vent blade.
Further, the shear-face angle of described first segment blade and the second joint blade is 135 °.
The utility model contrast prior art has following advantage: simple in structure, utilizing increases a rivet hole blade, the disposable flow process of finishing the valve seat operation in the upper flange operation, avoided the secondary clamping that causes because of the cutter problem, guaranteed the range accuracy between rivet hole and the steam vent, and reduced one bore rivet hole use drill bit, reduced the cost of charp tool, enhance productivity.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
Referring now to accompanying drawing, further describe the utility model.
As shown in Figure 1, cutter is bored in a kind of one-shot forming, comprise handle of a knife 1, knife bar 2 and moulding section 3, knife bar 2 is located at handle of a knife 1, and moulding section 3 is located at knife bar 2 tops, and moulding section 3 comprises first segment blade 31 and the second joint blade 32, the second joint blade 32 is located at knife bar 2, first segment blade 31 is located at the second joint blade 32, and first segment blade 31 sizes are provided with arc groove 21 less than the second joint blade, 32, the second joint blades 32 with knife bar 2 junctions.
In order better to reach the boring effect, realize disposable operation being finished, first segment blade 31 is for boring the rivet hole blade, the second joint blade 32 is for boring the steam vent blade, and the shear-face angle of first segment blade 31 and the second joint blade 32 is 135 °, has avoided the secondary clamping that causes because of the cutter problem, guaranteed the range accuracy between rivet hole and the steam vent, and reduced one bore rivet hole use drill bit, reduced cutter and cost of labor, enhance productivity.
Above-described the utility model embodiment does not constitute the restriction to the utility model protection domain.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
