Abstract

The utility model relates to a straightener for U-pipe benders, which comprises a bracket, and two straighteners for tubes of different diameters. The four corners of the hollow bracket are respectively provided with locating pieces, and the centers of the two sides are respectively provided with supporting blocks. The two straighteners of different styles are respectively fixed to the upper surface and the lower surface of a revolving bottom plate which is connected with the supporting blocks in the center of the bracket by a shaft connected with a driving box. The four corners of the lower surface of the revolving bottom plate, which correspond to the locating pieces, are respectively provided with locating posts. The utility model has the advantages that the utility model is fixed to the upper surface and the lower surface of a flat plate two straighteners of different styles, and the straighteners are switched through the rotation of the flat plate. Therefore, the straighteners of the whole U-pipe bender occupy small space and can be conveniently adjusted when used.

Description

The coalignment of U-bend machine

Technical field

The utility model relates to a kind of parts of bending machine, particularly a kind of coalignment of U-shaped tube bending machine.

Background technology

Coalignment is the part of long automatically U-shaped pipe machine, when bending machine carries out alignment to need to two or more caliber, and the just essential coalignment that is equipped with more than two kinds and two kinds.

Its configuration of existing two kinds of coalignments generally has two kinds: a kind of is parallel-moving type, is about to two kinds of coalignment levels and is installed on the guide rail, and when changing these two kinds of coalignments, employing moves horizontally, and therefore whole coalignment takes up room bigger.Another kind is stacked, with two kinds of vertically opposite placements of coalignment, switches when using, and comes the lifting coalignment by cylinder, therefore coalignment is adjusted to the right place more complicated and difficulty.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and coalignment that a kind of U-bend machine that takes up space little, easy to adjust is provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

The coalignment of U-bend machine, the coalignment that comprises support and two kinds of different tube diameters, support hollow, four jiaos respectively are provided with positioning piece, respectively establish a back-up block in the middle of two sides, the coalignment of two different sizes is separately fixed at two up and down of revolution base plate, and the revolution base plate is connected on the back-up block on support top by axle, axle is connected with driving box, and four jiaos of the lower surfaces and the keeper corresponding position of revolution base plate are provided with a reference column.

Compared with prior art, advantage of the present utility model is: the coalignment by two kinds of different sizes is fixed on dull and stereotyped top and bottom, therefore coalignment is switched in rotation by flat board, and the shared space of the coalignment of whole U-bend machine is little, adjusts also very convenient during use.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the side view of Fig. 1.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, the coalignment of U-bend machine, support revolution base plate 1 by support 7, support 7 hollows respectively are provided with a positioning block 6, two sides centre all around and respectively establish a back-up block 5, coalignment 2, coalignment 3 are installed in two of revolution base plate 1, revolution base plate 1 is connected on the back-up block 5 by axle, and axle is connected with the driving box 4 of band handwheel 41, and four jiaos of the lower surfaces and locating piece 6 corresponding positions of revolution base plate 1 are provided with a reference column 11.

During normal the use, locating piece 6 stationary positioned posts 11, the coalignment 2 on the coalignment revolution base plate 1 of U-bend machine just can carry out alignment to the U-shaped pipe.When needs during with the coalignment 3 of another kind of specification, unclamp locating piece 6, with handwheel 41 rotating drive casees 4, driving box 4 drives revolution base plate Rotate 180 degree, this moment, originally the coalignment 3 of another specification below the revolution base plate forwarded to above the revolution base plate, therefore this coalignment 3 just can use, and sees Fig. 2.

Claims

1, the coalignment of U-bend machine, it is characterized in that: the coalignment that comprises support and two kinds of different tube diameters, support hollow, four jiaos respectively are provided with positioning piece, respectively establish a back-up block in the middle of two sides, the coalignment of two different sizes is separately fixed at two up and down of revolution base plate, and the revolution base plate is connected on the back-up block on support top by axle, axle is connected with driving box, and four jiaos of the lower surfaces and the keeper corresponding position of revolution base plate are provided with a reference column.
