, the 9th hole C1, the tenth hole C2,11-holes C3 and the 12nd hole C4 are according to 90 ° of circumferential arrangements on the circle that diameter is R4.
Referring to Fig. 1 and Fig. 6, the recess hole 3 that at least one is matched with Circular cutter 1 on platform 4 is cut, is adopted in the present invention
With flat cutting platform 4, several equidistant recess holes 3 are provided on cutting 4 upper surface of platform, the spacing etc. between recess hole 3
In the minimum widith R of cutting, Circular cutter 1 agrees with 3 phase of recess hole respectively, thus realize the equal in width cutting of prepreg tape, point
Cutting 4 upper side of platform has positioning end face, and positioning end face and the spacing of a nearest recess hole 3 for Distance positioning end face are equal to minimum
Distance R is cut, so that cutting clout is the smallest cutting width, there is the bore 7 of installation lead screw in cutting 4 side of platform.
Specifically, cutting 4 side of platform is provided with bore 7 referring to Fig. 6, bore 7 is used to install lead screw 10, and due to lead screw
The presence of connector 8, offers hole in bore 7, and the center in hole and cutting platform 4 have an offset along the center line of length Fang Xi
From D4 (not having numerical requirements, need to formulate according to practical lead screw installation site), cutting 4 one end of platform is provided with positioning gear
Plate 13 cuts and offers recess hole 3 on platform 4, and recess hole 3 includes multiple grooves such as the first groove 24, the second groove 25, and first is recessed
Slot 24 is located at cutting 4 one end of platform, and for the setting of positioning baffle 13 in 24 side of the first groove, 24 other side of the first groove is the second groove
25；Each positioning baffle 13 can make the clout after cutting be expected to the preimpregnation that can be directly used for laying as effective width
Material improves stock utilization, but on condition that the 24 sideline distance D1 of the first groove of Edge Distance of positioning baffle 13 is greater than or equal to
Recess width on the minimum widith R of cutting, the first groove 24 and other cutting platforms should be greater than the thickness d of Circular cutter 1, together
When be less than cutting minimum widith R, it is ensured that the normal cutting of prepreg, (the first groove 24 and the ipsilateral sideline of the second groove 25
Distance D3 should be greater than or equal to the minimum widith R of cutting).The lateral distance D3 of first groove 24 and the second groove 25 should be waited
In cutting minimum widith R.
Tension force module after cutting prepreg and cutting is connected, and in the tractive force of the tension force module
Under be fed forward.
A method of the high accuracy positioning carving knife based on above-mentioned apparatus cuts more width prepregs, including following step
It is rapid:
Step 1: in installing Circular cutter 1 in not coax segments, specifically, the width of each cylindrical bump is R, if needing
The prepreg narrowband that width is R is made, it is only necessary in the upper installation Circular cutter of adjacent cylindrical bump；If desired
The prepreg narrowband that width is 2R is made, it is only necessary to cut circle in the upper installation for being spaced the cylindrical bump of a cylindrical bump
Knife；If desired the prepreg narrowband that width is R and 2R is made simultaneously, then it can be in the installation of adjacent cylindrical bump point
Cutter and again on the basis of this, installs Circular cutter on the cylindrical bump for being spaced a cylindrical bump, if you need to cut
The prepreg narrowbands of other width is then.Circular cutter axis is mounted on lead screw connector；
Step 2: prepreg is placed on cutting platform 14, and it is close to 13 side of position block；
Step 3: starting driving motor 9, opens on cold duct for controlling the valve of air cock, is passed through cold air；
Step 4: rotational lead screw 10, adjusts Circular cutter axis 2 and moves downward and corresponding with the groove on cutting platform 14,
Prepreg is contacted with Circular cutter, completes cutting, the prepreg narrowband after cutting is fed forward under the pulling force of next mechanism
To next mechanism, to realize the continuous parting-cut conveying of prepreg.
The present invention include can high-precision control cutting prepreg width Circular cutter axis, pacify on the shaft part of Circular cutter axis
The Circular cutter of dress, the cutting platform being used in combination with Circular cutter, and the mountable adjusting cutting of bore for cutting platform side
The lead screw of dise knife axis length travel provides the driving motor of rotating torque for Circular cutter axis, and is connected by crank mechanism
Cut platform and cold duct.The invention enables prepreg can be cut with high precision, and can cut simultaneously a plurality of commensurateiy wide or
The prepreg narrowband of person's unequal width, improves cutting efficiency, realizes an axis and is mostly used, lead screw adjusts Circular cutter axis longitudinal direction position
The optimum Cutting point so that it is determined that cutting is moved, the use of cold duct can reduce the temperature in cutting region, and cutting is avoided to presoak
Material trimming resin changes with fiber volume fraction, reduces the amount of resin being adhered on cutting tool, improves pre- after cutting
Soak the trimming quality of material.
The foregoing is merely the embodiment of the present invention, are not intended to limit the invention, all in spirit and original of the invention
Any modification, equivalent replacement, improvement and so within then, should all be included in the protection scope of the present invention.
