Abstract
The utility model discloses a kind of drill bit for valve opening reaming, it comprises cutter hub and cutting edge, cutting edge is positioned at the front end of cutter hub, cutting edge is with chip area, one is had through the cutting fluid spray-hole of cutter hub in cutting edge, this hole connects the outer cooling line of cutter hub, and cutter hub is along the circumferential direction upper is uniformly fixed with three longitudinal bracing slivers in 120 degree, and the rotary-cut diameter of cutting edge is less than support sliver rotating diameter.The reaming processing of this novel valve opening on multiway valve casting valve body, has working (machining) efficiency high, the feature that crudy is good.
Description
Technical field
The utility model belongs to field of machining, is specifically related to the drill bit structure of a kind of hydraulic multitandem valve valve opening reaming processing.
Background technology
Valve opening is in key position on hydraulic multichannel valve body, and its crudy directly has influence on the cooperation with spool, and then affects the quality of hydraulic valve assembly.In the process of valve opening, reaming is first manufacturing procedure, and allowance is large, and its working (machining) efficiency produces larger impact to the process time of whole valve body, and its crudy also directly affects follow-up accurately machined quality simultaneously.
Generally use three-flanged bone reamer processing valve opening at present, not only cutting force is comparatively large, and inefficiency, also can produce the annular iron filings being difficult to clear up simultaneously.From the valve opening after processing qualitatively, the form and position tolerance of its valve opening processed is large, such as: linearity, roughness are all relatively poor, is not well positioned to meet the requirement of producing and assembling, and brings very large workload to subsequent fine processing.
Summary of the invention
The purpose of this utility model is: the deficiency existed for existing drill bit, provides a kind of novel expanding drill for valve port, and it can improve working (machining) efficiency and the processing linear degree of valve opening, can solve a chip removal difficult problem in process simultaneously.
The purpose of this utility model is achieved in that
A kind of drill bit for valve opening reaming, it comprises cutter hub and cutting edge, cutting edge is positioned at the front end of cutter hub, cutting edge is with chip area, one is had through the cutting fluid spray-hole of cutter hub in cutting edge, this hole connects the outer cooling line of cutter hub, and cutter hub is circumferentially uniformly fixed with three longitudinal bracing slivers in 120 degree, and the rotary-cut diameter of cutting edge is less than three support sliver rotating diameters.
The utility model drill bit has following advantage and effect;
1, because cutting edge and cutter hub are longitudinally having an angle, the cutting output of cutting edge is large, improves stock-removing efficiency.
2, the support sliver diameter on cutter hub is greater than cutting edge diameter, play the guiding role in reaming procedure, and the linearity of processing metapore is good.
3, cutting edge is with chip area and cutting fluid spray-hole, and in working angles, iron filings wash away with cutting fluid, reduces iron filings cleaning difficulty, and cutting edge and support sliver can obtain sufficient Cooling and Lubricator, extend the service life of drill bit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model;
In figure; 1, cutting edge; 2, sliver is supported; 3, cutter hub; 4, cutting fluid spray-hole; 5, chip area;
Detailed description of the invention
Below in conjunction with drawings and Examples, specific implementation method of the present utility model is described further:
As depicted in figs. 1 and 2, a kind of drill bit for valve opening reaming, it comprises cutter hub 3 and cutting edge 1, cutting edge 1 is positioned at the front end of cutter hub 3, cutting edge 1, with chip area 5, has one through the cutting fluid spray-hole 4 of cutter hub 3 in cutting edge 1, this hole connects the cooling line outside cutter hub 3, cutter hub 3 is circumferentially uniformly fixed with three longitudinal bracing slivers 2 in 120 degree, and the rotary-cut diameter of cutting edge 1 is less than support sliver 2 rotating diameter.
Cutting edge 1 is carbide alloy, in working angles, iron filings concentrate in chip area 5, because cutting edge 1 has cutting fluid spray-hole 4, iron filings wash away with cutting fluid, owing to supporting sliver 2 guide effect, not only the hole processed ensure that the linearity in hole but also can improve stock-removing efficiency, reduces iron filings cleaning difficulty.
Claims (2)
