Abstract
A step counterboring cutter belongs to machining cutter field, which comprises a big diameter section 1 and a small diameter section 2 and is characterized in that: the small diameter section 2 is provided with a ring chipping discharging trough 3 positioned at the joint of the big diameter section 1 and the small diameter section 2. The utility model can increase discharging space of chippings so as to ensure smooth discharging of chippings from hole.
Description
One, technical field
The utility model relates to the machining tool field.
Two, background technology
At present, ladder counterboring cutter structure as shown in Figure 1: big warp is with little excessive naturally through interface.Under the situation of restriction of having ready conditions, cutter takes vertical ground (also being surface of the work) to carry out part processing downwards.If workpiece is materials such as cast iron, and the reaming surplus is bigger, downcuts iron powder because gravity factor can't be discharged in the hole smoothly, and the stairs of knives part is when being fed to the aperture chamfering, be subjected to gathering iron powder and cause resistance to increase unusually, can occur big through twisting off phenomenon through interface with little.
Three, summary of the invention
The purpose of this utility model is improved on cutter structure exactly, increases the discharge space of downcutting material, is beneficial to the cutting-out material and discharges in the hole smoothly, takes place to avoid cutter to twist off phenomenon.
Design of the present utility model is: a species stage counterboring cutter, relate to the big footpath section and the path section of ladder counterboring cutter, and it is characterized in that on the path section, having chip area.Chip area can be along cutter shaft to straight trough, but cannelure preferably perpendicular to axial direction.
Further scheme is the joint portion that chip area is positioned at big footpath section and path section.
The utility model shows that the step drill after the improvement expands the discharge space that cutter has obviously increased the excision thing owing to taked abovementioned technology by practical proof, guaranteed that the excision thing smoothly from the interior discharge of holing, effectively avoided cutter to twist off.This shows that the phenomenon of improving the ladder cutter that twists off has played effective prevention effect really, is comparatively desirable ladder cutter.
Four, accompanying drawing and explanation
Fig. 1 is a cutter structure cutaway view before improving.
Fig. 2 is the utility model cutter structure cutaway view.
Among the figure: 1---big warp; 2---little warp; 3---chip area.
Five, implementation
As Fig. 2, a species stage counterboring cutter relates to the big footpath section 1 and the path section 2 of ladder counterboring cutter, it is characterized in that having on path section 2 annular chip area 3.And chip area 3 is positioned at the joint portion of big footpath section 1 and path section 2.
Under the prerequisite that does not influence step drill expansion cutter intensity, in digging a suitable chip area 3 through 1 with little cutting greatly, can increase the discharge space of excision thing through 2 junction surfaces, guarantee to excise thing and in the hole, discharge smoothly.
