Description

Steel Plate Side Shear Camber Control Device {APPARATUS FOR PREVENTING THE STEEL STRIP ENTERED INTO SHEARING MACHINE FROM BEING CAMBERING}

The present invention relates to a steel sheet side shear camber control device, and more particularly, it is possible to fix and move the steel sheet to be sheared in order to prevent the shearing in a left and right state in the process of shearing the rolled steel sheet A steel sheet side shear camber control device.

In general, the rolled steel sheet is produced as a coil of the finished product by shearing the side and cutting the length in accordance with the required dimensions of the orderer.

As shown in FIG. 1, the front end of the side of the rolled steel sheet is sheared to the side of the steel sheet 21 conveyed along the transfer line by a steel sheet having a desired width dimension using a side shear equipped with a circular knife 20.

The side shearing operation of the steel plate 21 as described above is sheared to a certain width without any problem when the position of the transport line is a straight line, the phenomenon that the steel sheet is bent upward or warped upward due to various conditions are unstable, that is, camber ( Camber phenomenon occurs, which is a failure factor of the steel sheet to be sheared.

As described above, there are a number of main factors in which the steel sheet 21 being sheared is bent, but generally the rolled sheet steel that is curved like a bow is not rolled in a straight line due to heating conditions, cooling conditions, abnormal rolling equipment, etc. in the rolling process. In addition, while one of the shearing work is fixed by scraping, while the other side of the shearing is sheared as the shearing occurs, the phenomenon occurs, the steel sheet is bent when the shear equipment conditions are not met.

In order to solve this problem, conventionally, as shown in Figure 1, the gear box 34 axially coupled to the drive motor 31 pinion 33 before the steel sheet 21 enters the side shear 19 (19). The steel sheet 21 along the camber control roller 36 for guiding one side of the steel sheet 21 to be rotatably installed and enters the cam control guide 35 for guiding the other side thereof. 19), the camber phenomenon of the steel sheet 21 could be reduced to some extent, but the widthwise movement was possible in the longitudinal direction by the movement cylinder 36 which axially couples the camber control roll 37. For this reason, if the control plate is out of the shear during shearing, the camber phenomenon in which the steel sheet 21 under pressure is distorted occurs in multiple reflections, and thus the bending phenomenon of the rear end of the steel sheet is not improved.

In order to solve the above problems, the present invention by fixing the lower both sides of the steel plate with a magnet until the steel sheet is transferred to the side shear to completely suppress the camber phenomenon of the steel sheet to produce a steel sheet of good quality It is an object of the present invention to provide a side shear camber control device.

Hereinafter, the operation of the present invention will be described in detail.

Figure 6 is a functional diagram showing a situation of shearing the side of the steel sheet using the steel sheet side shear camber control device according to the present invention.

As illustrated in FIG. 6 and the drawings referred to while explaining the above configuration, the steel sheet side shearing camber control device according to the present invention first moves on a roll table, which is a steel sheet conveying line, to have a side shearing machine for width processing ( The steel plate 21 is fixedly moved from the bottom until it enters 19), thereby stably moving.

That is, the traveling rail 18 constituting the device moving means of the present invention is installed from a distance away from the side shearing machine 21, and is installed just before the side shearing machine 19, so that the device moving means slides it. It will move.

First, when the steel sheet 21 is first entered into the transfer line for moving to the side shearing machine 19, it passes through the upper portion of the steel sheet side shearing camber control device of the present invention,

At this time, the square block (1a) of the magnet (1) of the steel plate fixing means constituting the present invention is raised by the synergism of the elevating cylinder (2) to attach the lower both sides of the steel sheet (21),

If the square block (1a) is attached to the plate through the sheet, the feed rate of the steel plate 21 is temporarily faster than the speed of the device moving means, so that the forward and backward guide rails 22 of the upper plate 30 of the steel plate fixing means Is inserted into the sliding bed 23 formed on the lower plate 32,

Since the buffer spring 4 is inserted into both sides of the fixing bar 40 penetrating the lower plate fixing plate 4b fixed to the lower plate 32, the upper plate 30 slides the lower plate 32 to act as a buffer. Will happen,

This buffering action is further alleviated by stopping the upper plate stopper 25 protruding from one side of the upper plate 30 and the buffer stopper 24 formed on the lower plate.

In addition, the movable steel plate fixing means constituting the present invention is provided, the left and right positions of the lower plate 32 as the drive motor 7 and the lead screw 9 is variable to cope with elasticity according to the width of the steel plate 21 do.

As described above, when the lower both sides of the steel plate 21 is fixed by the steel plate fixing means of the present invention, the device moving means moves the steel plate fixing means.

While the steel plate fixing means attaches the plate 21 to the plate, the traveling motor 10 constituting the device moving means is driven.

When the driving shaft 12 is rotated by the driving of the driving motor 10, and when the driving shaft 12 is driven, a driving sprocket 13 fixed at both ends thereof is provided at a lower portion of the device base 100. Will rotate (15).

When the driven sprocket 15 is rotated, the pinion gear 27 coaxially coupled thereto rotates and is geared to move the rack gear 27a continuously formed on the lower surface of the traveling rail 18. As a result, the traveling wheel 16 of the device base 100 which is stably guided by the left and right guide wheels 29 and the upper and lower guide wheels 28 on the running rails 18 slides on the running rails 18. The steel sheet 21 enters the short run 19.

As described above, according to the present invention, the lower surface of the steel sheet 21 is fixed and transported to the side shearer 19 so that the steel sheet 21 is stably sheared without generating the camber phenomenon (bending phenomenon) of the steel sheet 21. It will be entered into (21).

As described above, the present invention can produce a steel plate of good quality by completely fixing the steel sheet entering the side shearing machine at the lower surface to enter the side shearing machine in the same way as the sheet feed rate, thereby completely suppressing the camber phenomenon of the steel sheet. There is an effect of significantly increasing the productivity of the steel sheet.
