The turntable 3 is symmetrically provided with a material limiter A4; the rotary table 3 between the limiters A4 is symmetrically provided with limiters B5; a limiter C6 (see fig. 3 of the specification) is installed between the limiters B5.
The limiter A4, the limiter B5 and the limiter C6 are respectively composed of a tension spring 17, a limit rod 18, a sliding block 20 and a guide roller 21 (see fig. 4 in the specification); a slide block 20 is slidably arranged on the turntable 3 through a guide rail 22; slider 20 is movable back and forth along guide rail 22; the two sides of the sliding block 20 are respectively provided with a guide block A19 and a guide block B28; the insides of the guide block a19 and the guide block B28 are provided with slide holes (not shown in the drawings of the specification).
The slide block 20 is fixedly provided with a limit rod 18; the hardness of the stop lever 18 is far greater than that of the workpiece 27, so that the problem that the stop lever 18 deforms when the hardness of the workpiece 27 is greater than that of the stop lever 18 is avoided.
The limiting rod 18 is connected with the guide block B28 in a sliding way through a sliding hole guide block A19; the purpose of this arrangement is that: firstly, the movement direction of the limiting rod 18 is limited through the guide block A19 and the guide block B28, so that the problem of deviation from a movement track is prevented; secondly, after the limiting rod 18 is inserted into the guide block A19, the guide block A19 and the guide block B28 can position the limiting rod 18 from two ends, so that when the limiting rod 18 is stressed, the guide block A19 and the guide block B28 position the limiting rod 18 from two ends, and the problem that the limiting rod 18 is easy to deform when being positioned on one side is avoided.
One end of the limiting rod 18 passes through the guide block B28 and is provided with a guide roller 21; the limit rod 18 is connected with the assembly cylinder 2 in a rolling way through a guide roller 21. The purpose of the guide roller 21 is to: the problem of abrasion occurring when the limit rod 18 is in direct contact with the assembly drum 2 is avoided.
The guide block B28 and the sliding block 20 are connected with each other through a tension spring 17; when the device is arranged, under the action of the elastic force of the tension spring 17, the sliding block 20 always has the trend of being close to the guide block B28, so that the limiting rod 18 always contacts with the inner wall of the assembly cylinder 2 under the action of the sliding block 20 and the tension spring 17, and the aim of controlling the limiting rod 18 to move through the adjusting rail A14, the adjusting rail B15 and the adjusting rail C16 is fulfilled.

The other end of the transmission rod 24 is fixedly provided with a bending roller 25. The purpose of the bending roller 25 is to: so that during the working process, when the bending roller 25 bends the workpiece under the cooperation of the limiting rod 18, the bending roller 25 can automatically rotate when being stressed; so that the bending roller 25 can bear force uniformly, and the problem that the bending roller 25 is easy to wear when being stressed on one side is avoided.
Bending holes 11 are symmetrically formed in the rotary table 3 between the material limiters and the bending device 10; the guide block A19 of each limiter is positioned at one side of the bending hole 11; the guide rail 22 is positioned at the other side of the bending hole 11; the purpose of this arrangement is that: so that the limiting rod 18 is positioned above the bending hole 11 after the limiting rod 18 is inserted into the guide block A19 during operation; thus, the limiting rod 18 can complete the bending work of the workpiece under the cooperation of the corresponding bending device 10.
