The present invention relates to a choke disassembling and assembling apparatus for an edge roll for rolling, and more particularly, to support chokes provided at both ends of the edge roll so as to be moved in the longitudinal direction of the edge roll without inclination to disassemble the choke and The present invention relates to a choke disassembling and assembling apparatus for a width rolling edger that is easily assembled.

In general, the edge roll used in the width rolling is used for a certain time, and then the surface is smoothly processed by polishing or the choke attached to both ends is dismantled and serviced.

In particular, disassembling and servicing chokes at both ends of the edge roll and assembling the finished choke back to both ends of the edge roll are very demanding, which has been used for a long time so that the bearing contact surface of the journal surface of the edge roll and the choke Since it is corroded and contaminated by foreign matter such as scale, much force is required to decompose the choke, and the ratio of length to diameter is very small compared to the general rolling roll used for thickness rolling. This is because the choke is inclined, requiring more force to disassemble or damaging the journal of the edge roll.

1 is a schematic configuration diagram showing a choke removal method of an edger according to the prior art, in which a plurality of screw shafts 120 having a predetermined length are arranged on the same line inside the main frame 110, and this screw shaft ( The choke set 130 is coupled to the choke set 130 to each of the 120 to move the choke set 130 along the screw shaft 120 when the screw shaft 120 rotates, so as to rotate the screw shaft 120. The drive motor 140 is provided with a configuration. In addition, an edge roll supporter 170 for supporting a lower portion of the edge roll 150 is included.

That is, after rotating the edger roll 150 in a lying down state, the choke 160 mounted on both journals 152 of the edger roll 150 is seated on the top of the choke rest 130. When the driving motor 140 rotates in the same state, the choke 160 of the edge roll 150 may be removed from the journal 152 by relatively moving the choke rest 130 while the screw shaft 120 connected thereto is rotated. It is. Of course, when the choke 160 is assembled to the journal 152 of the edge roll 150, the operation is performed in the reverse order.

However, in the conventional method of disassembling and assembling the edge roll choke, the center line of the choke 160 is applied to the lower end portion of the choke 160 by the choke support 130 only when the edge roll is laid down. As the center line of the journal 152 is inclined at an angle with respect to each other, the edge portion inside the bearing 162 of the choke 160 comes into contact with the journal 152. Not only does it increase the force required to disassemble from the journal 152 but it also causes damage to the surface of the journal 152.

In addition, when foreign matter such as scale is stuck to the joining portion of the journal 152 and the choke 160, the choke 160 is not easily disassembled from the journal 152 even when a large force is applied, thereby impacting the choke 160. In addition, the disassembly operation may be performed, and such an impact is directly transmitted to the journal 152, and the journal 152 may be deformed.

The present invention is to solve the above-mentioned conventional problems, the object is to damage the edge roll and choke by applying the force in the longitudinal direction of the edge roll to support the top of the choke as well as the bottom of the choke in the state of the edge roll laid down An object of the present invention is to provide a choke disassembling and assembling apparatus for an edge roll for rolling, which is capable of disassembling and assembling a choke without.

As a technical configuration for achieving the above object, the present invention provides a pair of choke rests configured to set the choke attached to both ends of the edge roll to the upper side with the edge roll lying on the top, and the choke. A screw shaft which is mounted to penetrate the settable and moves the choke settle relatively or near by the rotation thereof, a drive motor which rotates the screw shaft, and is located on the top of the choke and in the longitudinal direction of the edge roll. A support formed to have a long length, a choke support slidably mounted on both sides of the support and fixedly supporting the upper end of the choke, and choke moving means for moving the choke support to be relatively far or near. By providing the choke disassembly and assembling apparatus of the edge roll for width rolling.

The choke moving means of the present invention includes a cylinder fixed to the support and a rod connected to the choke support, and a hydraulic controller connected to move the rod of the cylinder forward and backward corresponding to the rotational speed of the drive motor. Characterized in that made.
