Abstract
The utility model relates to a gradually fading thread profile guiding tap, which is a taper with a taper angle of 0-60 DEG or a circle cutting tap. The utility model is characterized in that the thread profile starts from the first buckle of 30-120 DEG at the small end along the guiding tap in the gradual transition to the metric thread of 60 DEG standard thread profile or inch screw thread of 55 DEG standard thread profile. The corresponding angle can be selected according to different tapped and squeezed materials, the thread can be tapped and squeezed easily without tipping, the tapping and squeezing torque is small, the guidance quality is good, the finish of the thread is good, the friction force is small, the service life is long, and the utility model can be widely used for the guiding tapers of the self-tapping thread screw, the squeezing thread tap and the self screwed bolt by screw squeezing and the cutting tap of the screw tap.
Description
The utility model relates to the gradual change thread profile guide cone of the cutting cone of a kind of guide cone that is used for tapping screw, thread forming tap or screw extrusion tapping screw or screw tap.
The utility model is called for short self threading pin by tapping screw ISO1478-83() the guide cone development, the thread profile angle of self threading pin guide cone is constant, it is big to be screwed into moment, guides badly, friction is big, screw thread degree of finish is low.
The purpose of this utility model is a kind of applied range of design, and guidance quality is good, attacks and squeezes the good metric thread of screw thread degree of finish or the gradual change thread profile guide cone of inch screw thread.
Technical solution of the present utility model is on the basis of self threading pin guide cone, is modified into gradual change thread profile guide cone.Guide cone is that a kind of cone angle (3) is 0 °～60 ° circular cone or a truncated cone, the thread profile of guide cone is transited into 60 ° of basic-profiles of metric thread (2) or 55 ° of basic-profiles of inch screw thread (2) of big end gradually by (1) 30 °～120 ° beginnings of small end first button along guide cone.
Gradual change thread profile guide cone also can have several recessed cutting slots (4) on the screw thread of guide cone.
The utility model advantage compared with prior art:
Gradual change thread profile guide cone is attacked and is squeezed that the screw thread torsional moment is little, guidance quality good, machining screw degree of finish is good, friction is little, the life-span is long.
Below in conjunction with accompanying drawing, the utility model embodiment has been described:
Fig. 1 is conical gradual change thread profile guide cone.Fig. 2 is the gradual change thread profile guide cone that has cutting slot.Fig. 3 is 60 ° of thread profile schematic representation.Fig. 4 is 30 ° and crossfades into 60 ° of thread profile schematic representation.Fig. 5 is 120 ° and crossfades into 60 ° of thread profile schematic representation.
The utility model gradual change thread profile guide cone is used for the guide cone of tapping screw, thread forming tap and screw extrusion tapping screw or the cutting cone of screw tap.The screw thread of guide cone is metric thread or inch screw thread.
Guide cone is that a kind of cone angle (3) is 0 °～60 ° circular cone or a truncated cone, the thread profile of guide cone is transited into 60 ° of basic-profiles of metric thread (2) or 55 ° of basic-profiles of inch screw thread (2) of big end gradually by (1) 30 °～120 ° beginnings of small end first button along guide cone.
The small end first button thread profile (1) can be selected for use according to being attacked the performance of squeezing material on the guide cone.Select 30 ° of thread profile Fig. 4 that carry out the transition to 60 ° for use as plastics, bakelite, red copper.Low carbon steel, brass, duralumin can be selected the thread profile Fig. 3 that is 60 ° for use.Middle-carbon steel, Alloy Constructional Steel are selected the thread profile Fig. 5 that carries out the transition to 60 ° by 120 ° for use.
Also can have several recessed cutting slots (4) on the screw thread of gradual change thread profile guide cone.
Gradual change thread profile guide cone can be attacked according to different quilts and be squeezed material and select corresponding angle, makes to attack that to squeeze screw thread not turned again smoothly, attacks to squeeze that moment of torsion is little, guidance quality good, machining screw degree of finish is good, friction is little, the life-span is long.Can be widely used in the guide cone of tapping screw, thread forming tap, screw extrusion tapping screw or the cutting cone of screw tap.
Claims (2)
1, gradual change thread profile guide cone, be that a kind of cone angle (3) is 0 °～60 ° circular cone or a truncated cone, it is characterized in that: the thread profile of guide cone is transited into 60 ° of basic-profiles of metric thread (2) or 55 ° of basic-profiles of inch screw thread (2) of big end gradually by (1) 30 °～120 ° beginnings of small end first button along guide cone.
2, according to the described gradual change thread profile of claim 1 guide cone, it is characterized in that: on the screw thread of guide cone, have several recessed cutting slots (4).
