Problems solved by technology

The former of these two methods takes up a lot of space, and the latter cannot adjust the inclination angle of the straightening roller in a large range due to structural limitations, and because the inclination angle of the straightening roller is different from the rotation angle of the screw in the former or the screw in the latter There is no direct linear relationship between the moving distance of the bar, so the inclination angle of the straightening roller is not easy to detect or the detection accuracy is low

Embodiment Construction

[0014] As shown in Figure 1, a bracket 2 is fixedly connected to the bottom of the straightening roller 1, and the bracket 2 has a ring gear turntable, and the ring gear of the bracket 2 is meshed with the output end of a gear train 4; The end is below the rack 3, and the output end is above the rack 3. The gear at the output is a pinion. The gear train 4 is a known gear transmission mechanism, and its input end is meshed with the gear on the output shaft of the reduction gear; side. The output end of the reduction gear is below the frame 3. It meshes with the input gear of the gear train 4 on the same side. A photoelectric sensing unit composed of an angle measuring sensor is connected to the shaft of the reduction gear. Generally speaking, the relative inclination angle between the straightening roller 1 and the centerline of the round material to be straightened, that is, the straightening centerline, is α, and the bracket 2 and the straightening roller 1 are fixedly co...

Abstract

The method of regulating inclination angle of straightening roller includes setting the straightening roller on some bracket to form one integral capable of rotating around the gyration center of the bracket, and rotating the bracket to rotate the straightening roller so as to regulate its inclination angle. The gyration center of the bracket is the central axis of one gear train, the bracket has gear ring meshed with the gear train, and the gear train is driven with one motor driven speed reducer. Of the gear train, each of the gears has rotation angle in linear relationship with the inclination angle of straightening roller and great transmission ratio. The changed angle is measured with angle measuring sensor and other detection elements. The present invention has simple compact structure, precise rotation angle regulation, high precision and other advantages.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, in particular to a method for adjusting the inclination angle of a straightening roller applied to a skewed roller straightening machine. Background technique [0002] Inclined roll straightening machine is mainly used for straightening round materials such as colored or black pipes and rods, and is widely used in the metallurgical industry. The inclination angle of the straightening roller of the skewed roller straightening machine needs to be adjusted and changed according to the outer diameter of the straightened round material, and the adjustment accuracy is required to be high. The usual method of adjusting the inclination angle of the straightening roller adopts the adjustment method of the nut screw: one is to set a rotatable ball hinge nut with a sliding groove on the straightening roller seat. The rod is fixed in the axial direction, so the nut moves, thereby driving the straighte...
