Description

The screw tap of hard alloy

Technical field

The present invention relates to the screw tap of hard alloy, specifically a kind of use in machining, manufacturing industry new Instrument Two-end Tap Applied, with three straight troughs.

Background technology

It is well known that machine-building, one is to need lathe, and two is the instrument for needing manufacture, and Neither of the two can be dispensed.20th century Famous instrument " Ni Zhifu drill ", once won glory for the motherland, and Ni Zhifu comrade also becomes the outstanding representative of workman, always served as the whole nation Chairman of the Labor Union.It can be seen that importance of the manufacturing industry with good tool, good tool can just produce product.With Chinese machinery industry Unprecedented development is obtained, the demand of metal cutting tool increasingly increases, need more preferable instrument such as Two-end Tap Applied to expire The development of the existing production of foot.Generally, regular tap metal material being processed, due to designing incorrect, unreasonable structure, The reason such as size is wrong, makes screw tap processing technology not reach requirement, and poor product quality does not improve grade, and value is low, using the longevity Life is short, it is therefore desirable to carry out Fine design, innovation to this common screw tap, forms a kind of Two-end Tap Applied so as to process Quality is good, and product is superior, and utilization rate is high, and design is correct, rational in infrastructure, can make Two-end Tap Applied normal operation at work, work Performance is good, and running effect is good, so that it is guaranteed that working stability puts in place, machining accuracy is high, long service life;Overcome regular tap Wrong, unreasonable structure is designed, causes to process not in place, poor product quality, utilization rate are low, often occur tipping, blunt mouth etc. to lack Fall into.

Content of the invention

In order to overcome regular tap to design wrong, unreasonable structure, cause to process not in place, poor product quality, utilization rate Low, often there is the defects such as tipping, blunt mouth, the invention provides the screw tap of hard alloy, it is a kind of Two-end Tap Applied, with three Bar straight trough, design correct, rational in infrastructure, can normal operation at work, be connected firmly, favorable working performance, running effect are good, from And guaranteeing that working stability puts in place, machining accuracy is high, keen edge, long service life.

Technical scheme:The screw tap of hard alloy, including metal blade and metal shank, metal blade is connected with metal shank Body, steel edge portion be located at screw tap left part, metal shank be located at screw tap right part, it is characterised in that screw tap in cylindrical shape, Laterally disposed in the example shown, the left and right total length of screw tap is 105;Being excavated on the face of cylinder of screw tap from left to right has three Straight trough, three straight troughs are evenly distributed on the face of cylinder of screw tap, and correspondingly form three knife-band;The right-hand member of three straight troughs It is in all circular arc, the left and right total length of three straight troughs is respectively 50, and the bottom land of three straight troughs can be arcuate bottom, and this three Bar arcuate bottom guarantees that the core thickness of screw tap reaches 10;In three knife-band, mill has a sword tooth, adjacent two sword teeth respectively Between be ground out a sword groove;Sword tooth is in trapezoid shape, and sword groove is in reverse trapezoid shape;Sword tooth with sword groove can be highly 2.5—4.5㎜;The angle of left and right two hypotenuses of sword groove is 60 °;The excircle a diameter of 24 of metal blade;In steel edge On the excircle in portion and at the left side 11 of screw tap, relief grinding, one enclose relief grinding and become left cone from right to left, The left side of left cone is little, and the right side of left cone is big, and the relief grinding angle of formation is 15 °;It may be noted that:A left side for three knife-band The each autogenous grinding in end face outer ring has blade, and the relief grinding amount of blade is 1-2.5, wears into tap anterior angle for 8 ° -12 °, makes tread reach 9; Again on the excircle of metal blade and at the left side 34 of screw tap, relief grinding becomes a circle chamfering, chamfering from left to right For 30 °, right cone is consequently formed, the left side of right cone is big, and the right side of right cone is little, the right side of right cone A diameter of 16;The right side connection metal shank of right cone, the circle diameter of metal shank is also 16;In metal handle The right part in portion is lathed to square toes, and the upper and lower height of square toes is 12, and the forward and backward width of square toes is 12, a left side for square toes, Right length is also 12;Four right angles of the right side of square toes are lathed to arc angle respectively and ensure the disc of square toes right-hand member A diameter of 12;The screw tap of hard alloy can be made of high-quality stainless steel or Hardmetal materials.

The beneficial effects of the present invention is:There is provided the screw tap of hard alloy, it is a kind of Two-end Tap Applied, straight with three Groove, design correct, rational in infrastructure, can normal operation at work, be connected firmly, favorable working performance, running effect are good, so as to true Protect working stability to put in place, machining accuracy is high, keen edge, long service life.Regular tap is overcome to design wrong, structure does not conform to Reason, causes to process not in place, and poor product quality, utilization rate are low, often the defects such as tipping, blunt mouth occur, can meet enterprise Production, expands the social demand of product.
