Built-in no-side-gap gear angle adjusting device of inclined roller straightening machine

Abstract

The invention provides a built-in no-side-gap gear angle adjusting device of an inclined roller straightening machine. The adjusting device comprises a straightening roller, a roller base, a rack, an eccentric shaft, a transition gear, a speed reduction motor, a half gear ring, a box body, driving gears, a spring, an adjusting bolt, a positioning bearing and a bearing pedestal, wherein the straightening roller is fixed above the roller base through the bearing pedestal and a plurality of sets of bolts; the roller base is positioned on the inner side of the rack through the positioning bearing; the outer side of the rack is connected with the box body; a shaft of the speed reduction motor is sleeved with the driving gears, and one side of the shaft of the speed reduction motor is provided with the spring and the adjusting bolt; the driving gears can rotate in a meshed mode through the transition gear, the eccentric shaft and the half gear ring under the action of the spring. An included angle exists between the direction of the axis of the strengthening roller of the inclined roller straightening machine and the direction of the length of a strengthened pipe (or rod). When pipe rod materials with different diameters are strengthened and the diameters of the pipe rod materials change within a certain range, the pipe rod materials can be straightened just by changing the included angle without replacing the straightening roller.

Description

technical field [0001] The invention relates to a straightening roller angle adjustment device of a skewed roller straightening machine. There is an angle between the axis direction of the straightening roller of the skewed roller straightening machine and the length direction of the pipe (or bar) to be straightened. When straightening pipes and rods with different diameters, it is only necessary to change the included angle to achieve straightening of pipes and rods without replacing the straightening rollers when the diameter of the pipes and rods changes within a certain range. Background technique [0002] There are mainly two methods for the angle adjustment mechanism of the existing oblique roller straightening machine. (1) Linkage mechanism type: a four-bar linkage mechanism composed of a length-changing link between the angle adjustment device fixed on the slide seat or frame and the turntable or roller seat of the fixed straightening roller, through Changing the l...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the above-mentioned existing skewed roll leveler angle adjustment mechanism obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently
