Example 1

As shown in fig. 1 to 5, the present utility model provides a technical solution:

A manual pipe bending device for coiled pipes, which at least comprises a workbench 1, a bending die 2, a first support column 3, a second support column 4, a resisting column 5 and a spanner 6; the bending die 2 and the resisting column 5 are fixedly arranged on the workbench 1, a cavity for accommodating the first support column 3 is arranged at the central position of the bending die 2, and a spanner 6 is provided with a first through hole 7 and a second through hole 8 which are connected with the first support column 3 and the second through hole; the first through hole 7 is sleeved at the end part of the first support column 3, and the second through hole 8 is connected with the second support column 4; the second support column 4 is sleeved on the grooved pulley 12 in a sliding way, and a bending cavity is formed in the space between the grooved pulley 12 and the surface of the bending die 2.

Based on the above-mentioned structure, when needs spiral to bend to steel pipe 13 spare, will wait to bend steel pipe 13 and pass the chamber of bending, first support column 3 provides center of rotation for the rotation of spanner 6, makes spanner 6 card can rotate around first support column 3, simultaneously because groove wheel 12 slides and sets up on second support column 4, when bending steel pipe 13, steel pipe 13 is being bent mould 2 and is being guided the time of circling, groove wheel 12 can be moved along the length direction of second support column 4 voluntarily, and finally wait to bend steel pipe 13 of bending and bend mould 2's preset form.

As an example, a guide groove 9 is provided on the outer edge of the bending die 2, and the guide groove 9 is in a spiral rising structure along the length direction of the bending die 2.

By providing the spiral guide groove 9, the steel pipe 13 can be guided by the above-described structure, and can also be spirally raised along with the guide groove 9.

As an example, the top of the second support column 4 penetrates through the second through hole 8 and is welded with the wrench 6 into a whole, and a limit bolt for limiting the groove wheel 12 is arranged on the bottom of the second support column 4.

Based on the above structure, the second support column 4 penetrates through the second through hole 8, so that the second support column 4 and the wrench 6 can have more contact area, breakage of the second support column is prevented when the steel pipe 13 is bent, and the groove wheel 12 can be prevented from falling from the second support column 4 by arranging the limit bolt.

As an example, the level of the initial position of the guide groove 9 on the bending die 2 is not lower than the level of the groove wheel 12 at the bottom end of the second support column 4, and preferably, the level of the initial position of the guide groove 9 on the bending die 2 is the same as the level of the groove wheel 12 at the bottom end of the second support column 4.
