Detailed Description

For the purpose of illustrating the technical solutions and technical objects of the present invention, the present invention will be further described with reference to the accompanying drawings and specific embodiments.

With reference to fig. 1, the rib calibrating machine of the present invention comprises an installation workbench 1, a calibrating mechanism 2, a laser detecting mechanism 3, and a support roller 4;

the correction mechanism 2 can realize rolling correction of the rib 5 and can realize switching of correction modes; the laser detection mechanism 3 is arranged at the circle center of the outer contour of the rib 5, the laser detection mechanism 3 can realize tracking detection of different heights and different angles of the rib, and the next adjustment action is carried out by taking the comparison difference between the detected data and the graph paper information in the processor as the judgment basis, so that the correction precision is ensured constantly, when the correction parameter of the rib 5 changes, the laser detection mechanism 3 can move relatively, the position of the laser detection mechanism 3 is ensured to be at the circle center of the outer contour of the rib, and the detection function under different correction requirement parameters is realized; the supporting rollers 4 are arranged at the input end and the output end of the correcting mechanism 2, the supporting rollers 4 can keep the stable height and state of the ribs, the circular motion of the ribs is matched during correction, and when the rib correction parameters change, the supporting rollers 4 can move relatively and are fixed, so that the self-supporting function is realized.

With reference to fig. 2 and 3, the correcting mechanism 2 includes a fixed roller 21, a movable roller 26, a motor reducer 22, a hydraulic motor 23, a hydraulic oil cylinder 24, a mounting bracket 25, a variable pump, a servo motor, and an electric control system; two sets of fixed rollers 21 are fixedly arranged on the outer side of the mounting bracket 25, three sets of movable rollers 26 are arranged on the inner side of the mounting bracket, the fixed rollers 21 are connected with a hydraulic motor 23 through a motor reducer 22, the movable rollers 26 are connected with the hydraulic motor 23 through the motor reducer 22, each set of movable rollers 26 is connected with two sets of hydraulic oil cylinders 24, and the hydraulic oil cylinders 24 are fixedly connected to the mounting bracket 25; the variable pump, the servo motor and the electric control system realize accurate control and integral linkage of the extension of the hydraulic oil cylinder.

In operation, the support rollers 4 support the ribs 5 so that they are level with the rolls. Under the control of the electronic control system, the hydraulic motor 23 starts to rotate, which drives the fixed roller 21 and the movable roller 26 to rotate, so that the ribs move forward.

When rib correction parameters or modes change, the hydraulic oil cylinders 24 complete telescopic movement under the control of the control system, and each set of movable roller 26 is connected and driven by two sets of hydraulic oil cylinders 24, so that the accurate change of the movable roller on the horizontal plane position is realized.

Referring to fig. 4, the rib 5 is mainly formed by welding the web 5-1 and the panel 5-2.

Referring to fig. 5 and 6, after the rib is welded to the web and the face plate, the face plate 5-2 is deformed by thermal expansion and contraction due to high welding temperature, and both sides of the face plate 5-2 tend to bend toward the web 5-1 side. Referring to fig. 7-8, when the correcting mechanism is in the shape correcting mode of the panel 5-2, the fixed roller 21 and the movable roller 26 must be opposite to each other at the radius position of the rib, and apply a sufficient pressure to the rib panel 5-2 to perform the correcting operation.

Referring to fig. 9, after the rib welding and the shape correction are completed, the roundness of the rib is largely changed, and the overall roundness correction must be performed. When the correcting mechanism is in a panel roundness correcting mode, the control system must accurately control the positions of the rollers to enable the five sets of rollers to form a triangular shape so as to achieve a rounding effect. By adjusting the radius size between the three rollers and the two rollers, an accurate rib finished product meeting the size requirement can be obtained.

The working process of the rib correcting machine comprises the steps that the fixed roller 21 and the movable roller 26 rotate to drive the rib 5 to move forwards, rolling correction of the rib 5 is achieved, the laser detection mechanism 3 detects the correction effect and achieves real-time control together with a control system, finally, the corrected rib moves out of the correction mechanism 2 under the support of the support roller 4, and one rib correction operation is completed; the rib corrector can switch the correction mode (switching between the panel shape correction mode and the panel roundness correction mode), has good rib correction effect, saves time and labor and greatly improves the rib correction efficiency.
