Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
The first embodiment.
As shown in fig. 1-5.
A PVC plate friction stir connection method comprises the steps of firstly heating connection surfaces of PVC plates 3 and 4 to be connected through a heating block II 2 and a heating block I1 respectively (figure 1), enabling the heating temperature to reach 170 ~ 180 ℃, then taking away the heating block II 2 and the heating block I1, and enabling the connection surfaces to pass through a pressure device F1And a pressure device F27 (can be realized by adopting conventional technology, such as a hydraulic push rod, a screw nut and the like), extruding the heated two PVC plates 3 and 4 together (figure 2), wherein the pushing force is not too large, the plates are prevented from deforming, a limiting effect is achieved, and the plates are prevented from being separated by the stirring head, at the moment, rotating the stirring head 5 (shown in figures 3 and 4), simultaneously opening a heating wire 5-2 arranged in the stirring head 5 to rapidly heat the stirring head to 200 ~ 220 and 220 ℃, and finally connecting the two PVC plates into a shape by stirring and stirring of the stirring head 5, wherein the rotating speed of the stirring head 5 is 18000 ~ 20000rpm, the advancing speed of the stirring head 5 is 60-80 mm/min, the specific structure of the stirring head 5 is shown in the second embodiment, and the PVC plates obtained by stirring are shown in figure 5.
Example two.
As shown in fig. 1-4.
PVC boardThe material friction stir connecting device mainly comprises a heating part (figure 1), a stirring head 5 (figures 3 and 4) and a pressurizing part (figure 2), wherein the heating part comprises a heating block I1 and a heating block II 2, and the heating block I1 and the heating block II 2 are used for heating PVC plates attached to two opposite connecting surfaces of the PVC plates to be connected before friction stir welding; the pressure member being formed mainly by pressure means F16 and pressure device F27 composition, pressure device F16 and pressure device F27, the welding surface of the PVC plate is tightly pressed together in the stirring process, so that the stirring and friction process can be smoothly carried out; a hole 5-1 is drilled in the center of the stirring head 5, an electric heating wire 5-2 is installed in the hole, an arc concave circle 5-3 is dug in a shaft shoulder 5-6 of the stirring head, as shown in figure 3, 6 blades 5-7 are arranged in the arc concave circle 5-3, the blades 5-7 are gradually thinned from the middle to the edge of the shaft shoulder 5-6, and the blades 5-7 are S-shaped as shown in figure 4.
