SU1488059A1 - Straightening arrangement - Google Patents

Abstract

The invention relates to metallurgical finishing equipment and can be used to eliminate defects, in particular, to straighten the transverse curvature of large-sized aluminum plates, ribbed panels and profiles. The purpose of the invention is to simplify the design of the device, providing improved manufacturability of its manufacture and improved operation. When editing it is necessary to turn the correct rollers to the width of the workpiece. To do this, coupling halves 17 and 18 must be engaged and the drive shaft 9 rotates. When the shaft 9 rotates, the housing 7 moves the screw-nut together with the roller 5 along the guide 8 installed in the frame. When opening the coupling halves 17 and 18, the rotation of the shaft 9 causes only the roller 5 to rotate. 3 Il.

Description

 The invention relates to metallurgical finishing equipment and can be used to eliminate defects, in particular for straightening the transverse curvature of large-sized aluminum plates, finned panels and profiles.

The purpose of the invention is to simplify the design of the device, ensuring its manufacturability. made and improved operation.

. Figure 1 schematically shows the device, a cross-section; Fig. 2 shows the mechanism for moving the housing with an adjacent roller; on fig.Z - section aa in figure 2.

The straightening device consists of a frame 1 and traverse 2 and 3, carrying, respectively, supporting 4 and pressure .5 rollers. Replaceable rollers 4 and 5 by means of bearings 6 are installed in the housing 7, which are placed on the guides 8 of the crossbars 2 and 3. Inside the rollers, drive shafts 9 are mounted in parallel with the guides and receive rotation through the spindles 10 and gearbox 11 from the motors 12. On the - the shaft 9 is made of helical grooves 13 and a lip 14. Between the rollers and the shafts there are bushings 15 with internal screw lugs interacting with the screw grooves 13 of the shafts 9. The bushes 15 cooperate with rollers 4 and 5 through stoppers. 16, At the free end of each sleeve 15 there is a coupling coupling half 17. The second coupling half 18 is installed on the housing 7 and is clamped to the coupling half 17 by a spring 19. Removal of the coupling halves 17 and. 1 b is produced by control actuator 20.

The proposed design ensures the absence of rotation of the bushings-15 relative to the shaft 9, and consequently, and

the absence of displacement of the housings 7 with rollers 4 and 5 along these sleeves with the coupled coupling halves 17 and 18, if the angle of lift of the screw – nut pair (shaft 9 - sleeve 15) is less than the angle of friction of this pair. In the case when Q indicated the elevation angle is greater than the friction angle, it is necessary at the moment of uncoupling the coupling halves 17 and 18 to lock the sleeves 15 relative to the rollers 4 and 5 to prevent the spontaneous | 5 displacement of the housings with the rollers relative to the shafts 9. on the outer surface of each sleeve 15 there is a spring-loaded gear sleeve (not shown with a guide, key, interlocked with the coupling half 18, but in the inner cavity of each roller 4 or 5 - a gear clip (not shown) rigidly connected with a roller 25

The device works as follows. ,,

To correct the next defect of the plate 21 when the rollers 4 and 5 need to be adjusted to the width of the plate, the coupling halves 17 and 18 are connected by means of the control drive 20, fixing the sleeve 15 relative to the housing 7 to be moved with the roller. Thanks to this fixture and when the shaft 9 rotates, the sleeve 15 begins to move along the shaft due to the screw and nut screw, while moving

After installing the rollers 4 and 5 in width, the next plate 21 is edited.
