Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment
Fig. 1 illustrates the device of deposit belt deflection radius prepreg by hand, and the key component in described device is flexible compression roller 01.
As Fig. 2, pressure roller is made up of flexible gaskets 011, rigidity supporting structure 012 and the mandrel 013 of fixing the two, and mandrel 013, by being connected with holding rod 03, makes pressure roller 01 can transmission of pressure.The packing ring 0111 that two radiuses are bigger is had in flexible gaskets 011, and the packing ring 0112 that other radius is smaller.The about 0.3-1.0mm of radius of the radius ratio packing ring 0112 of packing ring 0111, like this, when they being arranged on rigidity supporting structure 012, the packing ring 0111 of both sides exceeds about 0.3-1.0mm than middle packing ring 0112, as shown in Figure 2, when prepreg 07 is placed on pressure roller, the effect that the part that packing ring 0111 exceeds serves fixing prepreg 07 edge, prevents prepreg 07 from deflecting away from.
As Fig. 3, when when prepreg 07 width of lay is less, by changing the installation site of packing ring 0111, make them in the middle part of pressure roller 01, thus reach the effect of fixing narrower prepreg 07.
Embodiment method forming step is: install flexible gaskets; Lay prepreg; Choose pressure roller initial position and lay direction; Determine connecting rod direction; Stationary positioned bar; Apply briquetting and carry out lay.Can not by automatic placement equipment, prepreg by means of only easy device deposit belt deflection radius, be applicable to shaping or its performance test of prepeg process.
The method of this kind deposit belt deflection radius prepreg by hand:
As Fig. 4, prepreg 07 is placed between pressure roller 01 middle washer 0111, provides the tractive force of 1-5N to make it keep straight, avoid occurring gauffer in laid course to the prepreg 07 of non-lay part.Because packing ring 011 is flexible material, under the effect of the pressure, the part that packing ring 0111 exceeds is crushed on lay face 06, thus reaches the effect of fixing prepreg 07.Lay direction in Fig. 4 as shown in figure sharp head direction,
As Fig. 5, the pressure roller 01 laying prepreg 07 is placed on lay starting point
o, and making its mandrel 013 direction perpendicular to lay direction, lay direction is as shown in Fig. 5 sharp head direction, then mandrel 013 direction of pressure roller 01 is deflection radius direction, the namely direction of connecting rod 04; Connect pressure roller mandrel 013 and connecting rod 04.According to deflection radius
r, from
opoint starts, and connecting rod 04 measures
r, namely obtain the center of circle deflecting circular arc
p, on connecting rod 04
pplace's stationary positioned bar 05.
According to required lay pressure, holding rod 03 connects briquetting 02, keep holding rod 03 perpendicular to lay face 06, and make the prepreg 07 of non-lay keep tension force,
opoint, along lay direction, does around axle motion around backstay 05, lay face 06 obtains belt deflector radius
rprepreg circular arc 07.
Fig. 6 illustrates that lay becomes the method for radius prepreg: when moving to
o 2 time, lay radius becomes
r 2 ,
o 2 place keeps holding rod 03 fixing and keeps tension force perpendicular to lay face 06, prepreg 07, unloads lower connecting rod 04 and backstay 05 from pressure roller 01; With reference to above-mentioned way, lay direction, as shown in Fig. 6 sharp head direction, connects pressure roller mandrel 013 and connecting rod 04 at pressure roller 01 opposite side, connecting rod 04 measures
r 2 obtain the center of circle of new deflection circular arc
p 2 ,
p 2 place's stationary positioned bar 05, makes pressure roller 01 do around axle motion around backstay 05, lay face 06 obtains belt deflector radius
