DETAILED DESCRIPTION

[0021] The utility model will be further described below in combination with the drawings and examples, and the mode of the utility model includes but is not limited to the following examples.

[0022] As Figure 1As shown, the embodiment provides a bend radius adjustable pipe bending device, which comprises a base 1, the base 1 is provided with a mounting plate 2, a plurality of adjusting holes 3 arranged in a ring are formed in the mounting plate 2, a circular ring-shaped fixed steel wheel 4 with a circular groove on the side is arranged on the mounting plate 2, the lower end of the fixed steel wheel 4 is provided with a support rod 5 corresponding to the position of the ring-shaped adjusting hole 3, and the support rod 5 is matched with the adjusting hole 3, the support rod 5 can be placed in the adjusting hole 3, the position of the fixed steel wheel 4 is fixed, and in addition, a gasket 6 is arranged on the support rod 5, which can ensure that the fixed steel wheel 4 is always in a horizontal position. Because a plurality of adjusting holes 3 are formed in the mounting plate 2, and these adjusting holes 3 are arranged in a ring, different diameters of fixed steel wheels 4 can be correspondingly arranged, and when the pipe to be bent needs to be bent into different radii, the fixed steel wheels 4 can be replaced to achieve the purpose.

[0023] A first bolt 7 is fixedly installed at the center of the mounting plate 2, the height of the first bolt 7 is higher than the top surface of the fixed steel wheel 4, a movable steel wheel 8 is arranged at the same horizontal plane as the fixed steel wheel 4, the center of the movable steel wheel 8 is provided with a second bolt 9, and a connecting rod 10 is further arranged, one end of the connecting rod 10 is provided with a through hole, and the other end is provided with an elongated adjusting slot 11, by passing the first bolt 7 through the through hole on the connecting rod 10, and passing the second bolt 9 through the adjusting slot 11, the position of the movable steel wheel 8 is limited, and the movable steel wheel 8 can adjust the position under the limiting action of the adjusting slot 11, in the actual use process, the connecting rod 10 can rotate around the second bolt 9 as the center, at the same time, the connecting rod 10 can drive the movable steel wheel 8 to move around the fixed steel wheel 4.
