Description

Pinch roll deviation correcting device for deviation of thin strip

Technical Field

The utility model relates to a thin specification hot rolling technical field, concretely relates to pinch roll deviation correcting device to thin take off tracking, the thin strip cast rolling of especially short flow batches the stage.

Background

The inlet pinch roll and the rolling mill form a tension section on the thin strip casting and rolling line, the rolling mill and the coiler form a tension section, the inlet pinch roll has a deviation correcting function, the outlet of the rolling mill and the coiler form a deviation correcting mechanism, the principles of the two deviation correcting mechanisms are different greatly, the inlet drives the whole cast strip to correct the deviation by the protruding point of the pinch roll, and the coiler can finish the deviation correction in a left-right moving mode. When the plate strip is normally centered, the front and back of the rolling mill and the coiling are normal; when the thin strip deviates slightly, the production line can produce normally, and the coil has wrong edges; when the thin strip is greatly deviated, the thin strip cannot normally enter a coiler, and steel is piled. The thickness of the thin strip is generally less than 1.5mm, so that the thin strip cannot be centered by the side guide plate like the traditional hot rolling.

The Chinese utility model with application number of CN202020018730.5 discloses an aluminum plate belt automatic centering and sewing device, which is used for centering an aluminum plate belt of a sewing machine, wherein two sides of the sewing machine are respectively provided with a back roll port and a front roll port; the centering and sewing device comprises a PLC controller, a back roll centering roller way arranged at the back roll port and a front roll centering roller way arranged at the front roll port; metal induction devices are arranged at the rear roll centering roller way and the front roll centering roller way; when the sewing operation is performed on a back-rolled aluminum plate strip head B on the back-rolled centering roller way and a front-rolled aluminum plate strip tail A on the front-rolled centering roller way, the PLC detects the positions of the strip head B and the strip tail A through the metal sensing device, controls the back-rolled centering roller way to convey the strip head B, controls the front-rolled centering roller way to convey the strip tail A, enables the strip head B and the strip tail A to move to an overlapped state required by the sewing operation, controls the back-rolled centering roller way and the front-rolled centering roller way to move back and forth, enables the overlapped part of the strip head B and the strip tail A to move to the centering position of the sewing operation, and can automatically center when the aluminum strip material is sewn.

Disclosure of Invention

In order to overcome the defect that the thin strip can not normally enter a coiler in the prior art, the pinch roll deviation correcting device for the deviation of the thin strip is provided, and the thin strip is enabled to be quickly aligned to a center line by improving the height of a deviation side.

In order to solve the technical problem, the utility model provides a following technical scheme: a pinch roll deviation correcting device for deviation of a thin strip is disclosed, wherein: the side baffle plates are arranged on two sides of the rolling mill, the rolled strip conveyed is arranged in the middle of each side baffle plate, one end of each side baffle plate is connected with the coiling machine, the pinch rolls are arranged on the side baffle plates, and the pinch rolls are connected with the hydraulic machine.

Preferably, the pinch roll is divided into a first pinch roll and a second pinch roll, the second pinch roll is arranged on the side shield between the rolling mill and the coiler, and the first pinch roll is arranged on the side shield on the other side of the rolling mill.

Preferably, the hydraulic press is divided into a first hydraulic press and a second hydraulic press which are respectively connected with the first pinch roll and the second pinch roll.

Preferably, the second pinch roll is provided with a sensor.

The utility model has the advantages that:

the utility model discloses to the thin strip casting and rolling of short flow batch the stage, through pinch roll, the conveying that the hydraulic press control rolled the area, the problem of skew when the thin strip conveying of reply, guarantee to take the centering, improve production efficiency.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying the present invention are described in detail below with reference to the accompanying drawings.

Example 1

The embodiment provides a pinch roll deviation correcting device for deviation of a thin strip, and as shown in fig. 1, the main structure of the device comprises a rolling mill 8 and a coiler 9, two sides of the rolling mill 8 and the coiler 9 are connected through side baffles 7, the middle part of each side baffle 7 can convey a rolled strip 6 to realize transportation of the thin strip, pinch rolls 10 are arranged on the side baffles 7, the pinch rolls 10 are connected with a hydraulic machine 11, and when deviation occurs, the hydraulic machine 11 is controlled to adjust the levelness of the pinch rolls 10 to enable the rolled strip 6 to be centered with a rolling center line.

Further, the pinch roll 10 is divided into a first pinch roll 1 and a second pinch roll 2, the second pinch roll 2 is arranged on a side baffle 7 between a rolling mill 8 and a coiling machine 9, the first pinch roll 1 is arranged on the side baffle 7 on the other side of the rolling mill 8, adjustment of the rolled strip 6 in different transmission links is achieved, and a tension section formed by the inlet pinch roll 1 and the rolling mill 8 and a tension section formed by the rolling mill 8 and the coiling machine 9 on the strip casting and rolling line are independently responded. Preferably, the hydraulic press 11 is divided into a first hydraulic press 4 and a second hydraulic press 5 which are respectively connected with the first pinch roll 1 and the second pinch roll 2, so that levelness adjustment of different pinch rolls 10 is realized, deviation is corrected, and the thin strip can be quickly centered.

Further, the second pinch roll 2 or the side baffle 7 at the position of the second pinch roll 2 is provided with an inductor 3, such as a laser range finder, an infrared sensor, an infrared automatic inductor and the like, for monitoring and sensing the offset. When the rolled strip 6 deviates from the rolling center line, the sensor 3 obtains a signal, and adjusts the levelness of the second pinch roll 2 through the second hydraulic press 5, so as to pertinently challenge the deviation phenomenon of a tension section between the rolling mill 8 and the coiling machine 9, realize the centering of the thin strip and ensure the normal production.
