Abstract

PURPOSE:To roll and straighten a steel sheet by one set of equipment by providing a phase changing device of planet rolls to a planetary type rolling equipment formed by arranging plural upper and lower planet rolls around a pair of sun rolls respectively. CONSTITUTION:A planetary type rolling equipment formed by arranging plural upper and lower planet rolls 8, 9 around a pair of sun rolls 2, 4 respectively, is provided with a phase changing device of planet rolls and is used for rolling and straightening in common. When a steel sheet S is rolled by said equipment, the sheet S is passed between the planet rolls 8 and 9 by waking the phases of the rolls 8 and 9 coincide with each other; when its shape is straightened, the sheet S is passed between the rolls 8, 9 by changing their phases from each other. In this way, the rolling and straightening of a steel sheet are performed by one set of the equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rolling straightening device capable of both rolling a steel plate and straightening the flatness thereof, and a method of using the device.

[Prior Art] When rolling and shape-correcting a steel plate, rolling S! A straightening device and a straightening device are provided separately, and the shape of the steel plate after rolling is corrected by the straightening device on the downstream side. This is true even if the rolling equipment and straightening equipment are planetarium-type equipment, but if the rolling equipment and straightening equipment are installed separately, equipment costs and
There were problems such as high construction costs and difficult maintenance and inspections.

[Objective of the Invention] The purpose of the present invention is to reduce equipment costs, construction costs, etc., and to facilitate maintenance and inspection by combining a planetarium-type rolling device and a straightening device. This is Shishino.

According to the present invention, a plurality of planetary rolls (upper and lower drive rolls) each provided around a pair of upper and lower sun rollers (upper and lower drive rolls)
Because it is equipped with a device that changes the phase of the substructure roll),
By adjusting the phase of the planetary rolls, both rolling and shape correction can be performed with one device.

"Example" FIG. 1 shows an embodiment of the invention.

A lower drive roll 2 rotatably supported on a lower drive roll axle box 3 and a lower drive l-'-le 4 rotatably supported on a lower drive roll axle box 5 are disposed between the left and right housings 1. The upper and lower straightening roll cages 1 are fitted to the necks of the upper and lower drive rolls 2.4 so as to be rotatable relative to the upper and lower drive rolls 2.4, and the upper and lower straightening roll cages 6. A plurality of upper and lower straightening rolls 8.9 which are driven upward and downward to the upper and lower driving rolls 2.4 and in contact with the outer peripheries of the J-rules 2 and 4 can be freely rotated at required intervals in the circumferential direction of the upper and lower drive rolls 2.4. It is pivoted to.

A gear 11 is fixed to a shaft 10 that can be rotated by a drive gA position (not shown), and the gear 11 is meshed with a gear 12 carved in the lower straightening roll cage 6, and a clutch 13 is provided at both ends. A gear 15 is fixed to the shaft 14, and the gear 15 is meshed with a gear 16 carved in the lower straightening roll cage 7.

A bevel gear 11 is fixed to the shaft 10, and a bevel gear 19 is fixed to the input shaft 18 of the clutch 13,
Bevel gears 21 and 22 are fixed to the upper and lower ends of an intermediate shaft 20 vertically arranged between the shaft 10 and the input shaft 18, and the bevel gear 21 is connected to the bevel gear 11 and the bevel gear 2.
2 are meshed with the bevel gear 19, respectively.

In addition, 23 in the figure is a lowering device for the lower drive roll shaft box 3, and 24
2 is a roll bending cylinder that applies roll bending to the upper and F drive rolls 2 and 4 through upper and lower roll bending shaft boxes 25 and 26;
8 is the hydraulic pressure.

When using the above apparatus as a rolling mill, as shown in FIG. 2, the phases of the upper and lower straightening rolls 8.9 are adjusted so that the upper and lower straightening rolls 8.9 are positioned directly below and directly above at the same time. Then, the upper and lower drive rolls 2 and 4 are driven, and the shaft 10 is also driven. For this reason, the upper and lower drive wheels 2,
4 rotates, while the torque of the shaft 10 is applied to the gear 11.12.
is transmitted to the lower straightening roll cage 6 to rotate the lower straightening roll cage 6, and the bevel gear 17.21, intermediate shaft 20, bevel gear A7-22.19, clutch 13
, gear ~15.46 to the lower straightening roll cage 1, and the lower straightening roll cage 7 rotates. Therefore, the upper and lower straightening rolls 8.9 revolve around the outer peripheries of the upper and lower driving rolls 2 and 4 due to the rotation of the upper and lower straightening roll cages 6.7, and the frictional force with the upper and lower straightening rolls 8.9 It rotates due to
The rolled plate S is rolled.

On the other hand, when correcting the shape of the rolled plate S,
Clutch 1 with upper and F drive rolls 2 and 4 stopped
3 and rotate the shaft 10.

Therefore, the lower straightening roll cage 6 rotates, and the upper straightening roll 8 moves in the circumferential direction of the lower drive roll 2 together with the lower straightening roll cage 6. When the phase of the upper straightening roll 8 deviates from the pitch of the lower straightening roll 9 by 1/2 pitch, the shaft 10 is stopped.

Whether or not the phase has shifted by a predetermined m is detected by a lenser such as a pulse generator attached to the drive device of the shaft 10.

The phase of the upper straightening roll 8 is a predetermined (
6) If the deviation occurs, connect the clutch 13 and drive the upper and lower drive rolls 2 and 4 and the upper and lower straightening roll cages 6.7 to straighten the rolled plate S by the upper and lower straightening wheels 8.9.
Shape correction is performed. The situation in this case is as shown in FIG.

In addition, in the embodiment of the present invention, the phase of the upper straightening roll is changed during shape correction, but it may also be implemented by changing the phase of the lower straightening roll, without departing from the gist of the present invention. that various changes may be made within the scope;
Of course, etc.

[Effects of the Invention] According to the rolling straightening device and the method of using the device of the present invention,
The ability to perform both rolling and shape correction with one device allows for consolidation of equipment, reduction of equipment costs, and reduction of construction costs by shortening the line, making it ideal for medium-sized production lines. Various excellent effects can be achieved.
