Problems solved by technology

This kind of side guide plate has fast response speed and high overall control precision, and can smoothly realize the corresponding position and pressure control according to the strip threading situation. However, this kind of side guide plate also has the following problems in actual use: because the lining plate is directly connected to the strip steel. If there is contact, there will be wear and tear, and the liner needs to be replaced frequently. The liner and the guide plate body, and the guide plate body and the push rod must be detachable connections such as pin connection. Clearance, coupled with machining errors, lead to the fact that the body of the guide plates on both sides often cannot guarantee the state of the slightly positive bell mouth or even the negative bell mouth state. Accumulative errors such as wear and deformation, deformation caused by long-distance guide plate body stress release, and the value of the bell mouth will also change, which is not within the reasonable range initially set.
For example, Chinese patent CN103920750A discloses a "Hot Rolling Line Coiler Front Side Guide Plate System", which reduces strip friction by adding guide wheels to the guide plate body, thereby improving the edge of the strip steel, but This solution does not have any bell mouth adjustment method. Once the bell mouth changes due to pin wear and other reasons, it has no bell mouth correction function.
Chinese patent CN102527771A discloses "Mobile Hot Rolling Coiler Front Side Guide Plate and Its Moving Guide Device", which ensures that

Embodiment 1

[0034] Example 1 : see figure 1 , the side guide plate has a side guide plate body 1 on the transmission side and the working side of the transmission roller table, and the distance a, a', b, b' from each side guide plate to the rolling center line CL is called the single-side opening at the corresponding position degree; the distance a+a', b+b' between the inner surfaces of the two side guide plates is called the total opening degree of the side guide plate at the corresponding position; and the opening degree a+a' on the entrance side of the side guide plate minus the opening degree b+ on the exit side b' is called the bell mouth of the side guide plate, and correspondingly, the difference a-b, a'-b' of the opening degree of one side is called the corresponding one-side bell mouth of the side guide plate. Practice has proved that it satisfies the relationship: b= b', 0

Embodiment 2

[0041] Example 2 : see Figure 1-Figure 4 Usually, the bell mouth can be measured by using the downtime such as process roll change, if the bell mouth is found to be out of the accuracy range, then loosen the bolts, and adjust the corresponding amount of the corresponding amount by rotating and fixing the coupling half 17 in the corresponding direction according to the deviation value. The indexing angle is sufficient. If it is adjusted to the bottom diameter reaming hole or the outermost top diameter expansion reaming hole, and the bell mouth of the side guide plate is still not adjusted to the required control accuracy, then the inner gear sleeve of the movable half coupling and the outer ring gear mesh Disengage, rotate the synchronous shaft 10, and drive the rack-type push rod 5 on the outlet side to move in the corresponding direction. After moving the corresponding number of teeth, close the coupling, and then perform fine adjustment according to the above method, and...

Abstract

The invention relates to an adjusting device for a horn mouth of a side guide plate of a hot rolling coiler. The adjusting device is characterized by comprising a side guide plate body, a gear shaft, a rack type push rod, a horn mouth adjuster, a synchronizing shaft, a synchronous coupling and a driving oil cylinder, wherein the gear shaft is arranged below the rack type push rod, the side guide plate body is connected with the rack type push rod through a side guide plate connecting pin, the gear shaft is connected with the synchronizing shaft through the horn mouth adjuster and the synchronous coupling, and the driving oil cylinder is connected with the side guide plate body through an oil cylinder connecting pin.

Description

technical field [0001] The invention relates to an adjustment device, in particular to a bell mouth adjustment device and an adjustment method for a side guide plate of a hot rolling coiler, belonging to the technical field of metallurgical machinery. Background technique [0002] The entrance of the coiler of the hot-rolled strip steel production line is equipped with an entrance side guide plate, which is used to guide the strip steel into the coiler smoothly, and clamp the strip steel to align with the rolling center line, so as to reduce the misalignment of steel coils, tower-shaped coils, etc. shape defects. There is one side guide plate on the transmission side and the working side of the transmission roller table, the distance from the inner surface of the drive side of the guide plate to the inner surface of the working side is called the opening of the side guide plate, and the opening of the entrance side of the side guide minus the opening of the exit side Called...
