Description
Technical field
The utility model is related to a kind of screw tap for thread mill drilling, more particularly to a kind of interior cooling screw tap, belongs to one
Plant machining tool.
Background technology
Screw tap of the prior art is typically all integral structure, with a body, tapping is machined with body leading portion
The edge of a knife, is threading tool section, and back segment is handle of a knife section, has conical surface section in the leading section of threading tool section, and conical surface section is used to recognize hole,
Can accurately be positioned according to bottom outlet, the part that the conical surface section of threading tool section is later is cylinder section, outside threading tool section
Screw tool structure is offered on side face, and the chip area extended back by front end, existing skill are offered in threading tool section
The typically no cooling structure of screw tap in art, typically using direct Liquid injection cooling, cooling effect is bad.
Utility model content
The purpose of this utility model is to provide cooling screw tap in one kind, and knot is not cooled down to solve screw tap of the prior art
Structure, the bad problem of cooling effect.
In order to realize the above object the utility model is adopted the following technical scheme that：Cooling screw tap in a kind of, including body,
The leading portion of body is threading tool section, and back segment is handle of a knife section, and the leading section of threading tool section has conical surface section, threading tool section
The later part of conical surface section is cylinder section, and screw tool structure is offered on the outer peripheral face of threading tool section, and threading tool section is opened
The chip area extended back by front end is provided with, is opened with the intersection of cylinder section in conical surface section in each chip area of threading tool section
Cooling Holes are provided with, each Cooling Holes are by being opened in the feed liquor opened up on rear end face of the cooling duct of body central with body
Mouth connection.
Described Cooling Holes are along the radial hole for radially extending of body.
Described chip area is straight trough, and the front end of chip area has the tipper for being formed and cutting inclined edge.
Described chip area is four.
The cross section of described chip area is arc.
Cooling Holes, each Cooling Holes are offered in each chip area of the present utility model with the intersection of cylinder section in conical surface section
Connected by being opened in the inlet opened up on the rear end face of the cooling duct with body of body central, can be to this practicality
New to carry out interior cooling, cooling effect is very good.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment；
Fig. 2 is the sectional view of Fig. 1.
Specific embodiment
A kind of embodiment of interior cooling screw tap, in fig. 1 and 2, interior cooling screw tap is integral type structure, with a sheet
Body 1, the tapping edge of a knife is machined with the leading portion of body 1, is threading tool section, and back segment is handle of a knife section, in the front end of threading tool section
Portion has conical surface section 2, and conical surface section can accurately be positioned for recognizing hole according to bottom outlet, after the conical surface section 2 of threading tool section
Part be cylinder section 3, offer screw tool structure on the outer peripheral face of threading tool section, and offer in threading tool section
Four chip areas 4 extended back by front end, chip area 4 is straight trough, and the front end of chip area 4 has the tipper for being formed and cutting inclined edge
5, the cross section of chip area 4 is arc, the cross section of the part of tipper 5 at the rear chip area 4 that cross section here refers to, also
It is the cross section of the later part of tipper 5.Cooling Holes 6, the extension of Cooling Holes 6 are offered in the groove bottom part of each chip area 4
Direction for body 1 radial direction, it may also be said to Cooling Holes 6 be radial hole, Cooling Holes 6 be in threading tool section the conical surface section with
The intersection of cylinder section.Inlet is offered on the rear end face of body 1, inlet is inwardly provided with and communicated with cooling duct 7, cold
But passage 7 is in the centre of body 1, and each Cooling Holes is connected with cooling duct respectively.Could also say that each Cooling Holes
Connected with inlet by cooling duct.
Cooling Holes of the present utility model be radial hole can also be the center line with body before angle be acute angle hole.
