Description
Technical field
The present invention relates to a kind of plastic tube product line cutting machine, the rotary profiling of more particularly to a kind of plastic film capicitor
Cutter.
Background technology
Current plastic pipe cutting machine is carried out frequently with chipless cutting mode, by rotary cutting blade in tube surfaces
Produce turning effort and complete the cutting to tubing.In order to reduce the cutting blade in plastic pipe cutting machine use when be subject to hinder
Power and the chip producing, the cutting edge portion of cutting blade is typically relatively thin, simultaneously because cutting blade occurs in cutting process
Abrasion, so need often to change cutting blade.In order to reduce the waste of blade material, the afterbody of cutting blade can not be blocked up,
So general cutting blade just can be installed on tool rest after needing to be arranged on pressure knife block.As shown in figure 1, traditional cutting machine
In, the cutting blade 2 of strip passes through the first pressure knife block 1 and the second pressure knife block 3 is fixed on tool rest, and the length of cutting blade is remote
More than the length of pressure knife block, when tubing 4 reaches required position, cutting blade be aligned cutting position is pricked, tool rest band
Dynamic cutter rotates around pipe.Because tubing is warmmer, there is certain deformation, the Cutting Length of cutting process knife is long, easily send out
Raw flexural deformation, it may occur that left and right deviation, easily cuts into zigzag or cuts to crest, pipe is cut bad, then generates useless
Product.

Specific embodiment
With reference to the accompanying drawings and examples the present invention is further detailed.
As shown in Figures 2 to 5, a kind of plastic bellow cutting machine rotation imitates type cutter, including cutting blade 2 and stationary knife
Frame, cutting blade 2 includes point of a knife end 21 and shank end 22.Cutting blade 2 is located inside tool fixing frame, and cutting blade 2 stretches out stationary knife
The length of frame, between 1.1 times to 5 times of tubing 4 thickness, makes cutting blade 2 be only capable of stretching out the length that can cut corrugated pipe 4；
Tool fixing frame bottom be shaped as a ripple profile of tooth, the thickness of tool fixing frame bottom tubing 4 ripple bottom thickness 1.1 to
Between the 1.2 times it can be ensured that bottom of tool fixing frame cannot be contacted with ripple bottom surface, the side of ripple profile of tooth of tool fixing frame bottom with
The angle of tubing axis is that the inclination angle of the ripple on tubing 4 adds 1 to 5 degree.Tool fixing frame includes bottom and is provided with rectangular recess
The second pressure knife block 3 and the first pressure knife block 1, the first pressure knife block 1 and the second push type broach that are located in the second pressure knife block 3 rectangular recess
Block 3 is bolted.The centre position of the rectangular recess of the second pressure knife block 3 is provided with and determining that cutting blade 2 width mates
Position groove 31, the opening of locating slot 31 is located at the bottom side of the second pressure knife block, and the shank end of cutting blade and part point of a knife end are located at and determine
Inside the groove 31 of position, depth ratio cutting blade 2 thickness of locating slot 31 little 0.5 millimeter and above it can be ensured that the second pressure knife block with
Cutting blade can be compressed during the first pressure knife block locking.The internal one end near locating slot 31 opening of 31 liang of trough rims of locating slot sets respectively
There is corresponding salient angle.The bottom side of tool fixing frame is provided with the depression 13 of circular arc, and the radius of the depression 13 of circular arc is in tubing radius
Between 0.7 times to 0.95 times.
Further on the basis of such scheme, in Fig. 7 and Fig. 8, the first pressure knife block 1 is in the second pressure knife block 3
Side is provided with the pad 5 of wedge, and the medial surface of the first pressure knife block 1 is the inclined-plane mating with the pad 5 of wedge, the first pressure knife block 1
It is provided with the corresponding chute in position with the second pressure knife block 3, pad 5 is provided with through hole in the position of corresponding chute.Bolt is located at through hole
The interior position with pad 5 is fixed, and bolt can slide in the chute of the first pressure knife block 1 and the second pressure knife block 3, moves down pad
After piece 5, the spacing between the first pressure knife block 1 and the second pressure knife block 3 increases, and is equivalent to the thickness that increased tool fixing frame bottom, makes
Tool fixing frame can complete the position-limiting action in the bigger tubing of wave pitch；Conversely, after upper shifting pad 5, tool fixing frame is adapted to
The less tubing of wave pitch, prevents dislocation during cutting.
Waveform processing, the side of ripple profile of tooth of tool fixing frame bottom and tubing 4 axle of corrugated pipe is pressed in the bottom of tool fixing frame
The angle of line is that the inclination angle of the ripple on tubing adds 1 to 5 degree it is ensured that tool fixing frame can extend into the ripple of tubing when cutting
Inside, in cutting, knife is in bond firmly cannot offset to both sides, so that the corrugated pipe end face cutting out is neat to make tubing 4
Dislocation-free；The thickness of tool fixing frame bottom between 1.1 to 1.2 times of tubing 4 bottom thickness it is ensured that the bottom of tool fixing frame not
Contact with the ripple bottom surface of tubing 4, prevent from rubbing excessive and affect cutting result.
During cutting, tool fixing frame is inwardly deep into the corrugated interior of tubing 4, the two sides base of tool fixing frame and the ripple of tubing 4
Stricture of vagina contacts side surfaces, the bottom surface of tool fixing frame is not contacted with the ripple bottom surface of tubing 4, and the point of a knife end 21 of cutting blade 2 extends inwardly into
Behind the inside of tubing, tool fixing frame is rotated a circle around tubing 4 with cutting blade 2, due to completing position quilt in ripple for the tool fixing frame
Limit, can only rotate in ripple, so the position of cutting blade 2 is defined, prevent cutting blade 2 from producing skew and mistake occurs
Position, the yield rate of impact tubing.
