Fig. 2 is the stereogram of the utility model adjustment type circular die.
Fig. 3 is the side view of the smear metal tooth of the utility model adjustment type circular die.
The specific embodiment
See also Fig. 1 to Fig. 3, a kind of adjustment type circular die is processing and the externally threaded standard cutter of finishing, and it comprises a body 1, four smear metal teeth 2, four chip-removal holes 3, an adjusting device (not label).
This body 1 is to be made by tubular metal material.The middle position of this body 1 is offered a quincuncial perforate 12.
Inwardly be convexly equipped with out this four smear metal teeth 2 from the perforate 12 of this body 1, these four smear metal teeth 2 are shape and all parallel with axis direction linearly all, and per two adjacent smear metal teeth 2 are vertical mutually, and two adjacent smear metal tooth 2 places of relative position at grade.The upper end of this smear metal tooth 2 is provided with first cutting blade 22 that is certain taper with the end face of this body 1, the lower end of this this smear metal tooth 2 is provided with second cutting blade 24 that is certain taper with the bottom surface of this body 1, and the cutting edge line of this first cutting blade 22 and second cutting blade 24 is all with axially vertical.Between positioning tooth 26, the first cutting blades 22, second cutting blade 24 and these positioning tooths 26 that are provided with some triangular prismatic type vertical between first cutting blade 22 and second cutting blade 24, offer the locating slot 28 of some inverted triangle prismatics vertical on this smear metal tooth 2 with axis direction with axis direction.
This first cutting blade 22 and second cutting blade 24 are cutting tips of circular die, and this positioning tooth 26 and locating slot 28 play the smoothing effect.When threading, desire the excircle of workpiece post (figure does not show) of threading and stretch in the space that these four smear metal teeth 2 surround, rotate this adjustment type circular die or workpiece, just can process external screw thread.
Each chip-removal hole 3 is opened between per two smear metal teeth 2 on this body 1 vertically, and the space between these four cylindrical shapes that chip-removal hole 3 all is an opening, itself and this four smear metal teeth 2 has been connected to form above-mentioned quincuncial perforate 12.
A contiguous chip-removal hole 3 places cut-away portions body and form a slit 14 vertically on this body 1, a side inside that is positioned at this slit 14 on this body 1 offers a fixing cave (figure does not show), and the opposite side that is positioned at this slit 14 on this body 1 is offered one and had the bolt apertures 18 of internal thread.
This adjusting device 4 comprises said fixing cave and a bolt apertures 18 and a bolt 42.These bolt 42 1 ends are rotatable to be installed with at this fixedly in the cave, and the other end is provided with some external screw threads (figure does not show) and is located in the bolt apertures 18.Rotate this bolt 42, the screw-internal thread fit of the external screw thread of this bolt 42 and this bolt apertures 18, thereby can adjust the diameter of this body 1, also adjust four circumferential size that smear metal tooth 2 surrounds of body 1 inside, can be the excircle of workpiece post threading of the big or small external diameter of difference.
When cutting external screw thread, earlier this adjustment type circular die is placed in the screw die cover (figure does not show), tightens up with holding screw with this adjustment type plectane facing.Be enclosed within then on the excircle of workpiece post, rotational circle screw die (or rotational workpieces), simultaneously, axis direction at circular die imposes thrust, extract thread, and the thread side that cuts out by cover guiding, continue cover successively and cut out thread, begin to overlap and must keep the vertical of circular die end face and workpiece thread center axis when cutting external screw thread.
This adjustment type circular die has an adjusting device 4, therefore can adjust the circumferential size that 1 four smear metal teeth 2 of this body surround, and can be the excircle of workpiece post threading of the big or small external diameter of difference; This first cutting blade 22 and second cutting blade 24 are cutting tips of circular die, this positioning tooth 26 and locating slot 28 play the smoothing effect, the excircle of workpiece post is stretched in the space that these four smear metal teeth 2 surround, rotated this adjustment type circular die or workpiece, can process external screw thread.
