Numerical control plate rolling correction device

Abstract

The invention discloses a numerical control plate rolling correction device. The numerical control plate rolling correction device comprises a feeding mechanism, an output supporting structure, a roller, roller adjusting mechanisms and an indexable roller supporting mechanism, wherein the feeding mechanism is positioned at the front end of the device and used for conveying a housing plate to the roller; the output supporting structure is positioned at the tail end of the device and used for supporting and conveying out a rolled plate; the roller, the roller adjusting mechanisms and the indexable roller supporting mechanism are arranged in the supporting structure; the roller comprises two inner rollers and three outer rollers; the bottom end of each inner roller is connected with one roller adjusting mechanism, and the top end of each inner roller is connected with the indexable roller supporting mechanism; the bottom end and the top end of each outer roller are each connected with oneroller adjusting mechanism; and the indexable roller supporting mechanism and each roller adjusting mechanism can drive the end of the corresponding inner roller or the end of the corresponding outerroller to move in the horizontal direction. The numerical control plate rolling correction device is high in machining precision and correction efficiency, the plate rolling rounding process can be detected in real time, the rounding effect is corrected, the housing plate rounding correction precision is greatly improved, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of processing engineering, and in particular relates to a numerical control coiling correction device. Background technique [0002] At present, the rib panel and shell ring are rounded, and the operation method is: three-roll plate rolling machine. Similar industries also use four-roller coiling and rounding machines. Rib correction, operation method: use four-column hydraulic press to prepare mold to press shell ring correction, operation method: use special correction machine for shell ring, point-to-point correction of conical shell ring rounding, operation method: use special machine to press conical shell ring correction, operation method: manual There are several main problems in correcting the original three-roll plate bending machine: [0003] 1) The CNC system is not equipped, and the rolling size is manually adjusted; [0004] 2) With three-roller configuration, the edge of the product cannot b...

AI Technical Summary

Problems solved by technology

[0003] 1) The CNC system is not equipped, and the rolling size is manually adjusted;

[0004] 2) With three-roller configuration, the edge of the product cannot be rounded with a width of more than 300mm, and pre-pressing is required

[0005] 3) Cannot be corrected: different workpieces, wave shapes and ellipses generated during the rounding process, it is necessary to configure other calibration machines to correct the workpiece

[0006] 4) Unable to roll the tapered shell ring

[0007] 5) It cannot be detected automatically, and other detection equipment or tools are required to detect the workpiece

[0011] (1) Unable to perform bus calibration

[0012] In the existing four-roll coil rolling mill, the roll can only be moved and positioned along one axis in one direction, and the pressure correction of the roll on both sides of the radius line of the shell cannot be realized.

When the busbar of the shell plate deviates, it cannot be corrected

[0013] (2) There is a positioning deviation in the four-roller configuration:

[0014] Both ends of the roll move on a single axis, so it is impossible to accurately position the roll, and objectively there is a positioning deviation, which leads to deviations in the round shape and size of the coil

[0015] (3) The four-roll configuration cannot perform three-dimensional shape correction:

[0016] Four-roll coil rolling mill, equipped with three sets of rolls on one side and only one set of rolls on the other side, cannot correct the three-dimensional shape of the cylinder

[0017] (4) Cannot detect and correct automatically

[0018] None of the existing four-roller plate rolling and rounding machines is equipped with an automatic detection mechanism, so it is impossible to determine whether the plate rolling and rounding effect meets the technical requirements, and it is even more impossible to detect the plate rolling and rounding process in real time, and it is impossible to correct the rolling effect in time
