Technical Field

The invention relates to the technical field of plate strip rolling, in particular to a curling side guide combined type online adjusting device.

Background

In a hot-rolled strip mill, a side guide is generally arranged in front of a coiler, the side guide mainly can prevent the head and the tail of strip steel from deviating before the strip steel enters a coiler, and the side guide is arranged in front of the coiler and mainly comprises a horizontal section, a lead-in section, a transmission device and a synchronous shaft. The wear-resisting plates are arranged on the guide-in section and the horizontal section, and the guide-in section and the horizontal section of the side guide guard for installing the new wear-resisting plates are required to be replaced integrally and rapidly every day and even every shift.

As shown in fig. 5, the side guide leading-in section and the transmission structure are connected by a guide pin I, and the side guide horizontal section is connected with the transmission structure by a guide pin II; lead and defend round pin I and lead and defend round pin II and fix on transmission structure, the horizontal segment is fixed a position with leading and defending round pin II through fixed slide wedge, realizes that the horizontal segment leads and defends quick replacement, and the different leading and defending frame of changing is adjusted through the adjustment pad with the roll table clearance, and transmission structure promotes leading-in section and horizontal segment through fixed pin I, II.

The quality of products is directly influenced by the state of side guide, if the side guide is not well controlled, particularly, the roll shape is poor due to the occurrence of an opening bell mouth in a horizontal section, loose rolls or steel piling can be generated in serious conditions, and the band steel is damaged all over due to excessive abrasion of the abrasion-resistant plate, so that the difficulty and the cost of repairing in the next procedure are increased.

The main problem of current side guide mainly has three aspects:

1. the gap between the arc of the guide wear-resisting plate and the laminar flow roller way is unreasonable: because the wear-resistant materials of the guide and guard introduction section and the horizontal section are A3 steel, the horizontal section needs to be integrally replaced every day or even every shift, and the gap between the roller way and the wear-resistant plate needs to be adjusted by adding an adjusting pad after the integral replacement, so that the labor and the time are wasted, and the requirement on reasonable gap cannot be met;

the original guide connection mode has the problems of easy abrasion and troublesome replacement, and under the condition of different abrasion, a plurality of guide frames have larger deviation in elevation, levelness and straightness, cannot be adjusted and can only be stopped for maintenance or replacement, so the operation is complicated;

2. the abrasion of the pin shafts and the inner holes in different guide frames is different, so that the gaps between the guide frames and the uniform pin shafts I/II are different, the fixed wedge is loosened, the guide frames are easily inclined as shown in FIG. 6, and the position control is inaccurate;

3. the inlet straight-line section often has the condition of centering the bell mouth, the online adjustment is difficult, the effect of direct influence is caused, and the shape of the coil is poor.
