Abstract
The utility model provides a kind of plastic products flash cutting tool, including cylinder cutter hub, and the cutter hub includes handle of a knife and cutter head, and the cutter head is the semi-cylindrical in configuration with axial platform, and axial platform is opened up perpendicular to axial grooving；The arc surface of the semi-cylindrical in configuration is ground a scarf with grooving at an angle, and scarf upper end forms the positive stop lug boss I and positive stop lug boss II positioned at grooving both sides with axial platform；The positive stop lug boss I and positive stop lug boss II are globoidal structure；Further polish as blade scarf part corresponding with grooving.The utility model proposes flash remove cutter, can effectively overcome the easily stifled knife of existing flash trimming knife, cut more, leak the problem of cutting.
Description
Technical field
Plastic products machining tool technical field is the utility model is related to, more particularly on a kind of plastic bottle spue line
Burr flash cutting tool.
Background technology
Plastic products are articles indispensable in life, its production technology generally includes following steps：Plastic grain leads to
After crossing injection molding machine or bottle blowing machine heating extrusion forming, a punching mechanism is first passed around, unnecessary bulk regrinding-material overlap
Destroy, then again by the way that manually the burr (regrinding-material of fritter) on remaining spue line is repaired with knife.
With the development of the society, the gradual maturation of automatic technology, these profit margins are low, working environment is poor, work is strong
High post is spent also at last by mechanical automation to be substituted.It is usual that the equipment such as existing milling machine, engraving machine, manipulator realize that flash is repaired
Rotary-type knife tool and single-blade type knife tool is used, because the flexibility of plastic products and the characteristic expanded with heat and contract with cold, is used
Rotate knife tool and easily block up knife, and easily produced using single-point tool and cut and leak situation about cutting more.
Utility model content
The cutter of overlap after plastic products injection and burr finishing processing can be solved the utility model proposes a kind of
The easily stifled knife of existing flash trimming knife, cut more, leak the problem of cutting.
To realize above-mentioned technical purpose and the technique effect, the utility model solves by the following technical programs
State problem：
A kind of plastic products flash cutting tool, including cylinder cutter hub, the cutter hub include handle of a knife and cutter head, the cutter head
For the semi-cylindrical in configuration with axial platform, axial platform is opened up perpendicular to axial grooving；The circular arc of the semi-cylindrical in configuration
Face is ground a scarf with grooving at an angle, and scarf upper end is formed positioned at the spacing of grooving both sides with axial platform
Boss I and positive stop lug boss II；The positive stop lug boss I and positive stop lug boss II are globoidal structure；The scarf is corresponding with grooving
Further polishing is used as blade for part.
When such scheme cutter works, control scarf is bonded at an angle with plastic workpiece surface to be processed, spacing
Boss I and positive stop lug boss II limits cutter lateral shift positioned at repair flash both sides are treated.Cutter is along flash track sliding process
In, the blade cutting flash in the middle part of two boss, chip is discharged from grooving tail end, and the circular arc of two positive stop lug boss will not damage work
Part surface.
To ensure that on the outside of positive stop lug boss I and positive stop lug boss II be arc surface, stifled knife and the damage to non-flash position are reduced,
Angle between the scarf and grooving is 10~60 degree.
To avoid cutting more, the situation of notch out-of-flatness, for the grooving close to cutter head end set, blade width is 2~3mm.
Further, it is the intensity of guarantee cutter and the cutting effect of blade, the cylinder cutter hub a diameter of 3~
20mm, cutting groove depth are 1~18mm.
Further, axial platform and scarf are opened up into fillet with handle of a knife link position, avoids mechanical damage.
The advantages of the utility model is with effect：
1st, limit function is increased on the basis of conventional tool, blade is slightly above both sides boss, and positive stop lug boss can be preferable
Ensure Cutting trajectory and reduce the damage to workpiece surface；
2nd, blade is arranged at grooving end, reduces edge length, both can guarantee that preferable edge strength, be also avoided that
Situation about cutting more occurs；
3rd, set scarf to be contacted with workpiece cutting face, avoid plastics soft and the stifled knife that characteristic is brought that expands with heat and contract with cold
Problem.
Brief description of the drawings
Fig. 1 is a kind of plastic products flash cutting tool structure schematic diagram；
Fig. 2 is cutter head schematic diagram.
Figure number identifies：1st, handle of a knife, 2, axial platform, 3, grooving, 4, scarf, 5, positive stop lug boss I, 6, positive stop lug boss II,
7th, blade.
Embodiment
The utility model is described in further detail with reference to embodiments, but the utility model is not limited to these implementations
Example.
A kind of plastic products flash cutting tool described in the present embodiment, including a diameter of 6mm being made of handle of a knife 1 and cutter head
Cylindrical type cutter hub, cutter head is the semi-cylindrical in configuration with axial platform 2, axial platform 2 by close end open up one perpendicular to
Axial grooving 3,3 depth of grooving is 1.5mm, as shown in Figure 1.
As shown in Figure 2, the arc surface of cutter head semi-cylindrical in configuration is ground one with grooving 3 in 30 degree of scarf 4, beveling
4 upper end of face forms the cabochon positive stop lug boss I 5 and positive stop lug boss II6 positioned at 3 both sides of grooving with axial platform 2, in working angles
In, boss makes flash removal process by flash both sides to be cut, limitation blade prior to blade relative to the displacement of flash both sides
It is more steady.Further polish corresponding to the scarf 4 of 4 bottom of grooving, 7 structure of blade, a length of 2mm of sword are formed with 4 bottom of grooving.
Axial platform 2 and 4 tail end of scarf open up fillet with 1 crossover position of handle of a knife, remove the burr of sharp edge, exquisiteness peace
Entirely.
The operation principle of the present embodiment is：
Cutting tool installation manner can be run in the equipment of machining locus in numerically-controlled machine tool, engraving machine, manipulator etc. first, makes beveling
Face 4 is bonded with plastics part to be processed, and adjustment tool position makes flash to be cut and 7 position correspondence of blade, and starting machine makes knife
Tool is discharged along flash track Sliding cutting, chip from grooving tail end.
The embodiment of the utility model is described in detail above in association with attached drawing, but the utility model be not limited to it is described
Embodiment.For a person skilled in the art, it is right in the case where not departing from the principle of the utility model and spirit
These embodiments carry out a variety of change, modification, replacement and modification and still fall within the scope of protection of the utility model.
