Description
Technical field
The utility model belongs to drilling tool technical field, and in particular to a kind of screw tap with protective cover.
Background technology
Screw tap is a kind of cutter of machining internal thread, is provided with groove vertically.Also it is tap.Screw tap is according to its shape point
For straight slot screw tap, spiral fluted tap and spiral pointed tap (tip screw tap).Straight slot screw tap handling ease, precision is lower slightly, and yield is larger.
The screw thread process use of engine lathe, drilling machine and tapping machine is generally used for, cutting speed is slower.Spiral fluted tap is used for numerical control and added
Work center drilling blind hole is used, and process velocity is very fast, and precision is high, and chip removal is preferable, centering is good.Spiral pointed tap front portion has appearance to cut groove, uses
In the processing of through hole.The screw tap that tools factory provides mostly is coated taps, compared with the service life and cutting ability of non-coated taps
All improve a lot.The screw tap cutting load distribution of not isometrical design is reasonable, and crudy is high, but manufacturing cost is also high.Ladder
Tap for taper thread is frequently with not isometrical design.
Existing screw tap is when in use, it is necessary to use tapping oil, but tapping oil is when in use, easily spills into tapping
Around hole and in environment, pollute, and in tapping, iron ash caused by tapping also can four be scattered to around, be unfavorable for essence
Cleannes management service in processing environment；Existing screw tap not yet has the characteristics of collapsing iron ash and preventing tapping oil from spreading.
Utility model content
The purpose of this utility model is to provide a kind of screw tap with protective cover, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of screw tap with protective cover, including screw tap
Body, the shank the week side of boss fixed cover of the screw tap body are connected to bearing, and the week side of boss fixed cover of the bearing is connected to hard sleeve, institute
The one end for stating hard sleeve is fixedly connected with bellows, and one end of the bellows is fixedly connected with soft sleeve pipe, described soft
One end the week side of boss fixed cover of sleeve pipe is connected to the collar, and a side surface of the collar, which is fixed, is embedded with magnet.
Preferably, the bellows is transparent telescopic plastic film capicitor.
Preferably, the soft sleeve pipe is structure as a whole with the collar.
Preferably, the magnet is provided with 6 groups, and magnet is angularly uniformly installed on the collar on the basis of covering ring center
One side surface.
Preferably, the hard sleeve is hard copper pipe, aluminium-alloy pipe, plastic conduit or vulcanie pipe.
Preferably, the raw footage of the bellows is less than the length 1-2cm of screw tap this body running teeth portion.
Technique effect of the present utility model and advantage：The screw tap with protective cover, by the bellows-sheathed of setting in screw tap
The work teeth portion position of body, not only can be with dust-proof, and at work, is inhaled the collar in the week side of boss that need to be drilled by magnet, can
The four of iron ash dissipate during preventing the loss of tapping oil and tapping, protect the cleaning of environment and tapping hole week side, and ten
It is convenient to divide, and is easy to promote.
