After adopting above structure, compared with prior art, the utility model guide rail machine of twisting has the following advantages: because guide roller is provided with a pair of guide-localization circle, workpiece is placed in the guide-localization groove and is positioned, therefore workpiece is positioned in the guide-localization groove and can produce and swing in the writing that surpasses all the others process, thereby eliminated the processed workpiece phenomenon that is distorted, workpiece with the utility model processing, its precision is quite high, and the error amount of the perpendicularity of bending curve and horizontal plane reaches below the 0.3mm.
As a kind of improvement of the present utility model, described guide-localization circle and guide roller are for removably connecting.This detachable spiral connection that is connected to.This detachable connection can be adjusted the distances between two guide-localizations wheel, just adjusts the width of guide-localization groove, is positioned in processing request in the guide-localization groove to adapt to the different in width workpiece.
As another kind of improvement the of the present utility model, on the orienting roll wheel shaft, be provided with the vertical precision tunable arrangement of guide roller, this tunable arrangement is by the orienting roll wheel shaft, adjustable bearing split bearing, the adjustable shaft bearing, the fine setting bearing, the fine setting bearing block, bearing cap, clamp ring, tight fixed bolt, plane bearing is formed, the orienting roll wheel shaft is arranged to three grades of round platform formulas from the inside to the outside, be with adjustable bearing split bearing and adjustable shaft bearing on the one-level round platform, be provided with clamp ring after the adjustable shaft bearing, two, three grades of steps are provided with plane bearing and fine setting bearing, the fine setting bearing block, be provided with bearing cap behind the fine setting bearing block, be provided with tight fixed bolt in the centre bore of bearing cap, tight fixed bolt links to each other with the axial end of orienting roll wheel shaft.During adjustment, positive and negative rotation adjustable bearing split bearing seat or positive and negative rotary fine adjustment bearing block, driving the guiding crop rotation by the orienting roll wheel shaft moves axially, thereby adjust the guide-localization circle be arranged on the guide roller in same accurate plane, this be because guide roller at work after date one section the time, may produce certain deviation, at this moment can proofread and correct the guide roller aligning accuracy by tunable arrangement, when perhaps processing the workpiece of different size, different model, unlike material, can readjust the guide roller aligning accuracy by tunable arrangement, to reduce the error rate of every batch of workpiece.
As also a kind of improvement of the present utility model, clamping screw is provided with the control device of control clamping screw advance and retreat, and control device is to be connected to form successively by clamping motor, transition gear group, entrance pressure gear, clamping screw.Transfer the advance and retreat of control clamping screw by the positive and reverse return of compressing into motor, with control connection the pinch roller under the clamping screw press down or on receive.
As another improvement of the present utility model, also be provided with the light curtain detector that monitors the amount of compressing into that is connected the pinch roller under the clamping screw on the clamping screw.Light curtain detector has been arranged, and the press-bending radius error that can accurately control workpiece is in 0.1mm.
