[specific embodiment]
Below in conjunction with drawings and Examples the utility model is elaborated.
As shown in Figure 1-Figure 3, tube rolling press device 1 of the present utility model comprises: driving mechanism 11, the pinch roller 12, the pressure roller 13 that are driven by driving mechanism 11, wherein pinch roller 12 outer surfaces are provided with the rolling groove that extends along circumferentially, and pressure roller 13 outer surfaces are provided with the circumferential protrusions of extending along circumferentially.Tube rolling press device 1 further comprise be used for transmission pressure roller 13 near or away from the thread transmission 14 of pinch roller 12.In the present embodiment, this thread transmission 14 comprises by the guide pillar in the substrate 15 of fixing tube rolling press device 1 141 and is bearing in the supporting device that the top board 142 on the guide pillar 141 is formed; The screw rod 143 that cooperates with screw on the top board 142; The slide block 144 that is connected with an end of screw rod 143.In addition, slide block 144 is socketed on the guide pillar 141, and can be slided along guide pillar 141 by screw rod 143 transmissions.Pressure roller 13 passes through bearing 131 rotating supports in the support holes of slide block 144.In addition, thread transmission 14 further comprises the spanner 145 that is arranged on screw rod 143 other ends.
As shown in Figure 4, the tubing 16 with pre-preparation during use is enclosed within on the pressure roller 13, and rotating spanner 145 is rotated down screw rod 143, and screw rod 143 drives slide block 144 and pressure roller 13 moves, and tubing 16 is pressed on the pinch roller 12.Driving mechanism 11 drives pinch roller 12 rotations, and then drive tubing 16 rotates in the lump with pressure roller 13.Then, the pressure by further rotating spanner 145 increases between pinch roller 12 and the pressure roller 13 is matched by the circumferential protrusions on the rolling groove cooperation pressure roller 13 of pinch roller 12 outer surfaces, rolls out circular protrusion on the surface of tubing 16.Because adopt thread transmission 14, the pressure between pinch roller 12 and the pressure roller 13 is relatively stable, thereby the height of the circular protrusion of tubing 16 surface formation is even.In addition, because pressure roller 13 cooperates with single pinch roller 12, the situation that the pressure distribution inequality makes tubing 16 distortion can not appear.Present embodiment further to the circumferential protrusions of major general's pressure roller 13 be used for sidewall with the collar nut adjacency be set to perpendicular to pressure roller 13 axially, make that tubing 16 surfaces are also axial perpendicular to tubing 16 with the circular protrusion sidewall of collar nut adjacency, and then increase the fixed effect of collar nut.
