Furthermore, the outer edge of the bending wheel is provided with a traction seat for drawing the pipe fitting, and the center of the traction seat is provided with a first pipe groove for penetrating the pipe fitting.

Furthermore, a positioning assembly for limiting the pipe fitting is arranged in the traction seat.

Furthermore, the positioning assembly comprises a pressing block and a locking bolt, and the pressing block is connected with the traction seat through the locking bolt.

Furthermore, a strip-shaped groove used for installing a bending wheel is formed in the workbench, and the bending wheel is rotatably arranged in the strip-shaped groove through a central shaft of the bending wheel.

Furthermore, a pipe groove II for penetrating through the pipe fitting is formed in the positioning seat, and the pipe groove II is formed corresponding to the pipe groove I.

Furthermore, at least three groups of bending units consisting of positioning seats and bending wheels are arranged on the workbench.

The beneficial effects of the utility model are that, through the pipe fitting positioning seat and the cooperation of the wheel of bending, realize manual bending, simple structure, it is with low costs, it is effectual to bend, the operation of bending of convenient small-scale pipe diameter pipe fitting.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic view of the working table of the present invention.

In the figure, 1, a workbench, 2, a positioning seat, 3, a bending wheel, 4, a central shaft, 5, a hand wheel, 6, a traction seat, 7, a compression block, 8, a locking bolt and 9, a strip-shaped groove are arranged.

Detailed Description

If fig. 1 is the utility model discloses a structural schematic diagram, a manual pipe bender is used to turn to return bend sets up on workstation 1, including the wheel 3 of bending that is used for the positioning seat 2 of pipe fitting location and is used for the pipe fitting to bend, positioning seat 2 and the supporting setting of wheel 3 of bending, and 2 levels of positioning seat set up at the upper surface of workstation 1, and the vertical setting of wheel 3 of bending is at 2 tip of positioning seats, and 4 tip of the center pin of wheel 3 of bending are provided with and are used for driving wheel body pivoted hand wheel 5.

The outer edge of the bending wheel 3 is provided with a traction seat 6 for drawing the pipe fitting, and the center of the traction seat 6 is provided with a first pipe groove for penetrating the pipe fitting. And a second pipe groove for penetrating the pipe fitting is formed in the positioning seat 2, and the second pipe groove is formed corresponding to the first pipe groove.

The traction seat 6 is welded and fixed on the outer edge of the bending wheel 3, the traction seat 6 of the bending wheel 3 is rotated to a horizontal position before bending operation, and at the moment, a first pipe groove in the center of the traction seat 6 and a second pipe groove formed in the positioning seat 2 are on the same axis, so that a pipe fitting to be bent can stretch into the pipe fitting.

And a positioning assembly for limiting the pipe fitting is arranged in the traction seat 6. The positioning assembly comprises a pressing block 7 and a locking bolt 8, and the pressing block 7 is connected with the traction seat 6 through the locking bolt 8.

After pipe fitting one end will be treated and bend in extending traction seat 6, utilize and insert the locating component who establishes in traction seat 6 to live pipe fitting end fixing, the lower surface of compact heap 7 corresponds the pipe fitting and sets to the arc, supports compact heap 7 pipe fitting upper surface through the cooperation of locking bolt 8 and nut to 3 rotation in-process of bending wheel can pull the pipe fitting tip and bend the operation.
