Abstract

The utility model discloses a pipe bender which can directly bend a pipe without the requirement of heating. The utility model is characterized in that one end of a press bending wheel 1 is connected with a blocking ring 2 through a bolt 3, and the press bending wheel 1 and the blocking ring 2 can rotate correspondingly; the press bending wheel 1 is connected with a shaft 5 through a key 4 so as to form an integral body; the shaft 5 penetrates through a support frame 6 which is connected with a wrench 7. The utility model has the advantages of high work efficiency, simple structure, quick pipe bending operation and labor saving.

Description

Pipe bender

The utility model relates to a kind of bustle pipe machinery, especially a kind of pipe bender.

At present, during people's bustle pipe, generally be irritate going up sand in the pipe, add thermal flexure after utilizing gas fuel burnings such as acetylene, oxygen again, do time-consuming, effort like this, efficient is low, and exist potential safety hazard.

The purpose of this utility model is exactly to provide a kind of directly pipe bender of bend pipe that need not heat just for people.

The technical solution of the utility model is: a kind of pipe bender, it is characterized in that: an end of the wheel 1 that bends links together by bolt 3 and back-up ring 2, and the two can relatively rotate, and the wheel 1 that bends fuses by key 4 and axle 5, axle 5 passes support 6, and support 6 is connected with wrench 7.

The press-bending wheel 8 that is complementary with the wheel 1 that bends is connected on the support 6.

The wheel 1 and the size of taking turns the peripheral groove 9 on 8 of bending of bending should match with caliber.

The utility model has been owing to used press-bending wheel and support and long wrench, thus can crooked like a cork pipe, greatly having improved operating efficiency, the utility model is simple in structure, uses laborsaving convenience.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the structural representation of the simultaneously crooked many pipes of the utility model.

As shown in Figure 1, 2, the wheel 1 of bending is connected by polished rod bolt 3 with back-up ring 2, wheel 1 can relatively rotate with back-up ring 2 so that bend, axle 5 couples together the wheel 1 that bends with support 6, the wheel 1 that bends fuses by key 4 again with axle 5, can rotate round the wheel 1 that bends to guarantee support 6, the press-bending wheel that is complementary with the wheel 1 that bends 8 is connected on the support 6 by polished rod bolt 10, and can relatively rotate with support 6, be welded with a long spanner 7 on the support 6, so that it is laborsaving to work together.

Pipe bender shown in Figure 3 is processed with the peripheral groove of two different tube diameters on its pinch roller 11, thus crooked two tubes simultaneously, in like manner, also flexible many pipes, caliber can be identical also can be different.

During use, at first the opening on back-up ring 2 and the support 6 is forwarded on the straight line,, move handle 7 then and just can make pipe bend to required angle round the wheel 1 that bends so that scurry into pipe.In like manner, utilize the relatively rotating between wheel 8 and the support 6 of bending, can follow the second order buckling pipe, promptly tube bending is become Type.
