The specific embodiment
As Fig. 1～shown in Figure 3, the long steel pipe rotary pressing processing of this belt tension device is made up of the frame of installing on three same axis, wherein tail frame 14 provides fixedly core power, mid frame 5 provides revolving force, headstock 11 provides drawing tension, also include processed steel pipe 2 and be arranged on the core 3 of steel pipe 2 inside, outward turning pivoted frame 4, spinning roller 6, traction chuck 10, wherein outward turning pivoted frame 4 is installed on the mid frame 5 of equipment and relies on bearing 7 to be connected with centre frame 5, be 120 ° of distributions on the outward turning wheel carrier 43 identical spinning rollers 6 of diameter are installed, these 3 spinning rollers 6 not only can be along with outward turning wheel carrier 4 rotates around mid frame 5 axis, can also rotate along the axis of self, outward turning wheel carrier 4 rotates at power drive lower edge mid frame 5 axis together with spinning roller 6 in mid frame 5, the described desire that is positioned at is ground the core 3 that approaches steel pipe 2 inside that process, be fixed in by a pull bar 1 on the tail frame 14 of equipment, and can not rotate, the steel pipe 2 that desire is ground thin processing is enclosed within on this core 3, and does relative slip with core 3 under external force along core 3 axis;
The front end of described steel pipe 2 is connected with a traction chuck 10, drawing oil cylinder 12 on the headstock 11 of this traction chuck 10 and the equipment of being connected is connected, under the pulling force effect of drawing oil cylinder 12, steel pipe 2 moves by core 3 and the space that the spinning roller 6 that rotates leaves, and spinning roller 6 stone rollers that constantly are rotated are thin, reach by the purpose of calendering processing.
Operation principle of the present invention is as follows:
After steel pipe 2 front ends are admitted between core 3 in the mid frame 5 and the spinning roller 6 (the steel pipe port is Vehicle Processing in advance, requires to adapt to the gap), there are a tension force to drag steel pipe 2 at the front end of steel pipe 2 and move to headstock 11 directions.Simultaneously, power 9 drives travelling gear 8 rotations by power transmission shaft.Gear 8 is fixed on the outward turning wheel carrier 4, and outward turning wheel carrier 4 not only can also can make spinning roller 6 oneself rotate on the spinning roller frame 4 outside by bearing 7 around steel pipe 2 rotations.In this composite rotating process, spinning roller 6 (this device is that 3 120 degree distribute) is close to the outer wall of steel pipe 2, and between outer wall and core 3, the tube wall of steel pipe 2 is exerted pressure, by continuous rotation, steel pipe 2 is moved to headstock 11 directions by the tension force traction, make and the wall thickness reduction of steel pipe 2 reach the requirement of processing.
Entire equipment of the present invention is made up of three Vertical Racks, pull bar 1, sliding rail 13 and traction chuck 10, sees Fig. 2.In Fig. 2, the pull bar 1 that connects core 3 is fixed on the tail frame 14, and in whole steel pipe 2 rotary pressing processing processes, core 3 and pull bar 1 are limited motionless.Steel pipe 2 moves to headstock 11 directions along the sliding rail 13 that is arranged between mid frame 5 and the headstock 11 under the traction of tension force traction chuck 10.The drawing tension of tension force traction chuck 10 comes from the drawing oil cylinder 12 that is connected on the headstock 11, and hydraulic system of the present invention provides power for oil cylinder.
Under the coordination of above frame for movement, steel pipe 2 is sent into towards tail frame 14 1 ends from mid frame 5, is pulled out towards headstock 11 1 ends by mid frame 5, finishes and grinds thin process.
Spinning roller 2 is on 120 ° of outward turning wheel carriers 4 that along the circumferential direction distribute, and steel pipe 2 passes from outward turning wheel carrier 4 centers.Outward turning wheel carrier 4 relies on bearing 7 to be connected and to keep rotating freely with mid frame 5.When 4 rotations of outward turning wheel carrier, because spinning roller 6 closely contacts with the outer wall of steel pipe 2, so outward turning wheel carrier 4 drives spinning rollers 6 and rotates around the axis of spinning roller 6 self, and rolls steel pipe 2 outer walls, finish process, reach the goal of the invention of the heavy caliber that the present invention advocates, the processing of long steel pipe belt tension.
