Abstract
An expanding drill for a valve port comprises a cutter body, wherein the cutter body is provided with a through hole penetrating through the cutter body along the length direction, and the through hole is communicated with a cutting fluid spraying hole on the external circumference surface of the cutter body; a cutting edge is fixed at the front end of the cutter body; and a support guide strip is fixed on the cutter body behind the cutting edge. The expanding drill for the valve port is used for expanding and machining the valve port on a multi-way valve casting valve body and has the characteristics of high machining efficiency and high machining quality. With the adoption of the expanding drill for the valve port, the service life of a cutting tool can be prolonged, an annular scrap iron can be prevented from being produced, and the time for cleaning the scrap iron in the valve body is greatly reduced after the machining.
Description
Technical field:
The utility model relates to a kind of reamer, relates to a kind of reamer that is used for the processing of hydraulic multitandem valve valve opening in particular.
Background technology:
Valve opening is the key position of hydraulic multichannel valve body, and its crudy directly has influence on the cooperation with spool, and then influences the quality of hydraulic valve assembly.In the process of valve opening, reaming is the first road manufacturing procedure, and allowance is big, and its working (machining) efficiency will be to producing bigger influence the process time of whole valve body, and its crudy also directly influences follow-up accurately machined quality simultaneously.The tradition reamer is in the process that valve opening is processed; Cutting force is bigger, and efficient is low, can produce the annular iron filings that are difficult to clear up simultaneously; From processing seeing qualitatively of back valve opening; The form and position tolerance of the valve opening that it processes for example linearity, roughness is relatively poor relatively, can not well satisfy the requirement of production, assembling, and follow-up fine finishining is also had very adverse influence.
The utility model content:
The purpose of the utility model is the weak point to prior art, and a kind of valve opening reamer is provided, and working (machining) efficiency and crudy that it can improve the processing valve opening have reduced the cleaning difficulty of iron filings after the processing simultaneously.
The technological solution of the utility model is following:
The valve opening reamer; Comprise cutter hub, said cutter hub has a through hole that runs through its length direction, and the cutting fluid spray-hole on this through hole and the cutter hub outer circumference surface communicates; The front end of described cutter hub is fixed with cutting blade, is positioned on the cutter hub of said smear metal blade back to be fixed with the support sliver.
Described valve opening reamer, described cutting blade are stepped for what begin from front end that diameter increases successively on the direction that supports sliver.
Described valve opening reamer, described cutting blade is made up of four branch blades, these minutes blade be uniformly distributed with and be fixed on said cutter hub front end, described support sliver is made up of four branch slivers, these minutes sliver be uniformly distributed with and be fixed on the said cutter hub.Described support sliver, cutting blade constitute by carbide alloy.
Described valve opening reamer, said cutting fluid spray-hole is four row, is distributed on the outer circumference surface of said cutter hub, becomes 90 ° of angles each other, and described cutting fluid spray-hole and said support sliver or cutting blade are provided with separately.
Described valve opening reamer, the maximum gauge of said cutting blade is 0.02mm-0.03mm with the difference of the diameter that supports sliver.
The utility model beneficial effect is:
This novel staged carbide cutting blade that adopted has reduced the resistance that Tool in Cutting runs in reaming; Improve reaming linearity, roughness, improved the cutting operating mode of blade, therefore can in processing, adopt less allowance; So cutter because of the unequal factor of allowance causes the situation of damage can be less greatly; Reduce because of chipping allowance simultaneously, annular iron filings also disappear thereupon, greatly reduce iron filings cleaning difficulty.Cutting blade has increased carbide alloy at the back and has supported sliver, forms reaming processing guiding, has further guaranteed the reaming linearity.On the cutter hub, cutting blade and sliver place site distribution have the cutting fluid spray-hole, and cutting blade and sliver can be cooled off and lubricate fully in process, have prolonged cutter life.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that utility model B is to view;
Fig. 3 is a utility model A-A profile.
The specific embodiment:
Embodiment sees accompanying drawing 1,2,3, the valve opening reamer; Comprise cutter hub 3, cutter hub is a cylinder, and said cutter hub has a through hole that runs through its length direction; Be used in smear metal passage as smear metal liquid, and the cutting fluid spray-hole 4 on this through hole and the cutter hub outer circumference surface communicates, and can make that the smear metal liquid in the through hole sprays from these perforations; Play effect lubricated and cooling to cutter hub, at the front end of cutter hub a plurality of chip areas 5 are arranged, the iron filings that produce when being used for smear metal eject; The front end of described cutter hub 3 is fixed with cutting blade 1, is positioned to be fixed with on the cutter hub 3 of said smear metal blade back to support sliver 2.
Described cutting blade 1 is stepped for what begin from front end that diameter increases successively on the direction that supports sliver.Described cutting blade 1, support sliver 2 and constitute by carbide alloy; Described cutting blade is made up of four branch blades, and these four branch blades are uniformly distributed with the front end that is fixed on cutter hub, divides the quantity of blade also can be more than four certainly; For example 5,6,7,8 ... Etc. a plurality of; The variation of quantity does not influence this novel protection domain, and described support sliver 2 is made up of four branch slivers, these minutes sliver be uniformly distributed with and be fixed on the said cutter hub; Adopt cutting blade stepped, that process by carbide alloy can chipping allowance be distributed on the cutting blade of each step, chipping allowance is reduced greatly.Support sliver by carbide alloy and play the guiding role, the maximum gauge of said cutting blade is 0.02mm-0.03mm with the difference of the diameter that supports sliver.Can prevent cutter generation sideslip in the reaming process like this, the linearity and the fineness of the valve opening that assurance processes.
Said cutting fluid spray-hole 4 is four row, is distributed on the outer circumference surface of said cutter hub, becomes 90 ° of angles each other, and described cutting fluid spray-hole and said support sliver or cutting blade are provided with separately.
