Description
Technical field
The present invention relates to a kind of penknife hobboing cutter, the one kind for specifically referring to cut pencil processed for planetary penknife hobbing sets
There is the penknife hobboing cutter of chip-breaker.
Background technology
Make the hobboing cutter of planetary rotation come the penknife referred to as planet of the prepared pencil point of milling using around pencil end
Formula penknife, abbreviation penknife, the hobboing cutter is cylinder, the steel milling cutlery of multi-head spiral cutting edge；The upper end of hobboing cutter sets
There is the gear for driving its rotation；
After the branched pencil of the system of cutting, hobboing cutter milling efficiency and decline phenomenon, its reason the penknife of prior art can occur
It is that the wood chip clamping stagnation that hobboing cutter milling pencil wood pen holder is produced hinders being cut into for cutting edge in the spiral chip area of hobboing cutter
Give；Processing method is to take out knife rest from penknife together with hobboing cutter, manually by instrument by clamping stagnation in hobboing cutter chip area
Wood chip removes removing, and knife rest is reinstalled in penknife together with hobboing cutter again afterwards；So pick bits and come inconvenient to the use of user；Cause
This, there are the problems and shortcomings that wood chip clamping stagnation chip area, milling efficiency decline, manually pick bits inconvenience in prior art.
The content of the invention
For the problems and shortcomings that above-mentioned prior art is present, the present invention is using the setting chip breaking at the helical cutting edge of hobboing cutter
Groove, during work, the chip-breaker of hobboing cutter each helical cutting edge can form convex stupefied, the chip-breaker of previous helical cutting edge at cutting face
The previous convex stupefied of formation can be pruned by latter helical cutting edge and clamp-on the chip area of latter helical cutting edge, and previous convex stupefied wood chip exists
Extruding node is formed in the chip area of latter helical cutting edge, because the scale of construction for extruding node wood chip is more than the adjacent wood chip scale of construction,
Therefore, extruding node wood chip destroys the uniformity and continuity of wood chip in chip area when clamp-oning chip area, in making chip area
Wood chip generation chip breaking, the extruding of the node wood chip that is squeezed, chip breaking is by automatic-extrusion chip area；Row is clamp-oned by extruding destruction of a node
The uniformity and continuity of wood chip in bits groove, discharge wood chip automatic chip breaking, and empty chip area automatically to keep milling efficiency
Technical scheme, there is provided a kind of penknife hobboing cutter for being provided with chip-breaker, it is intended to make planetary penknife, reach and empty chip removal automatically
Groove, keep milling efficiency, without manually picking bits, user friendly purpose.
The object of the present invention is achieved like this：A kind of penknife hobboing cutter for being provided with chip-breaker, including hobboing cutter, gear, its
In：Described hobboing cutter is the steel milling cutlery of helical cutting edge cylindrical, that cylinder is provided with bull dextrorotation, each described helical edges
Groove referred to as chip-breaker of some cross sections in circular arc is provided with mouthful；In the cylinder of hobboing cutter, along imaginary helix, on to
Under, the chip-breaker is distributed to the 2/3 of hobboing cutter cylinder；The imaginary helix is around hobboing cutter cylinder, single head dextrorotation, pitch
Equal to the helix of hobboing cutter cylinder diameter；The center of hobboing cutter is provided with through upper and lower manhole referred to as cutter shaft hole；Two adjacent
The helical cutting edge between helicla flute be referred to as chip area；
Described gear is cylindrical straight gear steel gear, and the center of gear is provided with through hole corresponding with the cutter shaft hole and is referred to as
Axle hole；
Gear is fixedly connected on center above hobboing cutter, and the axle hole is corresponding with cutter shaft hole to be communicated.
Operation principle and beneficial effect
Using when, the present apparatus connects and composes hobboing cutter assembly through rotating shaft through the axle hole and cutter shaft hole and knife rest, described
Hobboing cutter assembly loads in penknife；
During work, hobboing cutter makees planetary rotation around the termination of pencil carries out milling, the chip breaking of hobboing cutter each helical cutting edge
Groove can all form convex stupefied at cutting face, the chip-breaker shape of previous helical cutting edge into previous convex stupefied can be cut by latter helical cutting edge
The chip area of latter helical cutting edge is removed and clamp-ons, previous convex stupefied wood chip forms extruding section in the chip area of latter helical cutting edge
Point, because the scale of construction for extruding node wood chip is more than the adjacent wood chip scale of construction, therefore, extruding node wood chip is destroyed when clamp-oning chip area
The uniformity and continuity of wood chip in chip area, make the wood chip in chip area that chip breaking to occur, the extruding of the node wood chip that is squeezed,
Chip breaking is by automatic-extrusion chip area；
The present apparatus clamp-ons the uniformity and continuity of wood chip in chip area by extruding destruction of a node, makes wood chip in chip area
Chip breaking is simultaneously automatically drained out chip area, planetary penknife is eliminated wood chip catching phenomenon, realizes automatic chip breaking chip removal, automatically
Chip area is emptied, milling efficiency is constant, without manually picking bits, facilitate user.
Additionally, the wood chip after present apparatus chip breaking is in clastic, and wood chip of the prior art without chip breaking is in strip, strip wood
Bits take up room it is larger, clastic wood chip take up room it is smaller, therefore using the present apparatus penknife appearance bits storehouse can accommodate
More pens bits, it is to avoid frequently topple over the trouble of pen bits, facilitate user.
Beneficial design is expanded
The shape of the cross section of the chip-breaker can also be rectangle, triangle or other geometries；
The rotation direction of the helical cutting edge can also be left-handed；
The rotation direction of the imaginary helix can also be left-handed；The pitch of the imaginary helix also may be selected arbitrarily large
It is small.
It is above-mentioned, the present invention using setting chip-breaker at the helical cutting edge of hobboing cutter, during work, hobboing cutter each helical cutting edge
Chip-breaker can all form convex stupefied at cutting face, the chip-breaker shape of previous helical cutting edge into it is previous convex stupefied can be by latter helical edges
Mouth is pruned and clamp-ons the chip area of latter helical cutting edge, and previous convex stupefied wood chip is formed in the chip area of latter helical cutting edge and squeezed
Pressure node, because the scale of construction for extruding node wood chip is more than the adjacent wood chip scale of construction, therefore, when extruding node wood chip clamp-ons chip area
The uniformity and continuity of wood chip in chip area are destroyed, makes the wood chip in chip area that chip breaking to occur, be squeezed node wood chip
Extruding, chip breaking is by automatic-extrusion chip area；The uniformity and continuity of wood chip in chip area are clamp-oned by extruding destruction of a node, is made
Wood chip automatic chip breaking is discharged, and empties chip area automatically to keep the technical scheme of milling efficiency, overcomes prior art presence
Wood chip clamping stagnation chip area, milling efficiency decline, the artificial problems and shortcomings for picking bits inconvenience, provide to obtain a kind of chip-breaker that is provided with
Penknife hobboing cutter, makes planetary penknife, has reached and has emptied chip area automatically, keep milling efficiency, need not manually pick bits, convenience
The purpose of user.
