Problems solved by technology
Most of the existing steel bar bending force limiting devices have a limited pressure that can be bent, even if they can be bent when bending thicker steel bars, they are easily damaged or the bending effect is not good; and when bending steel bars of different specifications or different angles , it is troublesome to adjust the distance between the position of the bending force limit device and the positioning axis of the turntable

Embodiment Construction
[0027] refer to figure 1 , figure 2 and image 3 , variable distance limit sleeve, which includes polygonal straight cylinder I1, polygonal straight cylinder I1 is provided with round hole I2, the axis of round hole I2 deviates from the center line of the two ends of the cylinder, and is connected with the center of the two ends 1. The sides 3 of the cylinder are parallel, and the axis has different vertical distances to different sides 3. The distance-variable spacing sleeve can be converted to different pressure-resistant bodies and obtain different spacing distances by rotating around the fixed circular axis. When applied to mechanical stoppers, because it can switch between different limit distances, it is convenient for the straight-line travel distance of the machine, and the frequent and rapid adjustment of the travel angle around the circle. The position of the through-hole and the technical parameters of the aperture have a large expansion space, which can be desig...

The invention discloses a variable-pitch stop collar and a steel bar bending mechanism applying the variable-pitch stop collar for manufacturing. The variable-pitch stop collar comprises a polygonal straight cylinder, a round hole is formed in the polygonal straight cylinder, and the axis of the round hole deviates from and is parallel to the line of centers of the two end faces of the cylinder. The steel bar bending mechanism applying the variable-pitch stop collar for manufacturing comprises a rotary plate, a bending component and a center component are arranged on the rotary plate, the center component comprises a locating shaft installed in the center of the rotary, a bending-resistant stop device avoiding swinging of steel bars is arranged outside the rotary plate, the bending component comprises another locating shaft installed outside the center of the rotary plate, a polygonal straight cylinder is sleeved on the locating shaft, a round hole is formed in the polygonal straight cylinder, and the axis of the round hole deviates from and is parallel to the line of centers of the two end faces of the cylinder. The variable-pitch stop collar has the advantage of being simple in structure, and the steel bar bending mechanism applying the variable-pitch stop collar for manufacturing has the advantages of being convenient to operate rapidly and capable of bearing a heavy load.
Description
technical field [0001] The invention relates to a distance-variable limit sleeve and a steel bar bending mechanism made by using the sleeve. Background technique [0002] In existing steel bar bending machines, the bending mechanism is mainly composed of a turntable and a positioning shaft. Two positioning shafts are installed on the turntable, and the turntable is equipped with a bending force limiting device to prevent the steel bar from swinging. When working, the steel bar is generally placed between the two positioning shafts of the turntable. When the turntable rotates, the steel bar will be bent. Most of the existing steel bar bending force limiting devices have a limited pressure that can be bent, even if they can be bent when bending thicker steel bars, they are easily damaged or the bending effect is not good; and when bending steel bars of different specifications or different angles , it is troublesome when it is necessary to adjust the distance between the pos...
