Description

Hydraulic limiting device for slitting line

Technical Field

The utility model relates to a indulge trimming processing field specifically is a hydraulic pressure stop device for indulge trimming.

Background

The slitting line is used for slitting coils such as galvanized iron, silicon steel sheets, stainless steel strips, aluminum strips and steel strips. The metal coil stock is cut into strip stock with various required widths, and then the strip stock is collected into small coils for the next working procedure. The process of uncoiling the coil stock from a large coil to a small coil can be realized in the processing process, so that if the situation of changing the transmission speed of a longitudinal shearing line is realized under the situation of keeping the rotating speed unchanged (when uncoiling the coil stock for cutting, because the metal coil stock is continuously coiled out, the diameter of uncoiling the coil stock is a process from large to small, the coiling coil stock is a process of coiling the cut coil stock, and the metal coil stock in the whole process is continuously increased, so that the diameter of the coiling coil stock is continuously increased, when the rotating speed of the machine is kept unchanged, the coil stock discharging speed of uncoiling the coil stock is continuously slowed, the coiling speed of the coiling coil stock is continuously quickened, and the change of tension can be realized due to the inconsistency of the speeds), and the change of the tension can cause a series of problems. The most common problem is the bending of the metal strip due to the change of tension after the metal strip is cut into strips of various widths, which finally results in the strip being a little higher than the proper track of the strip.

In the traditional method, a pit is built behind a rolling shear (shearing a metal coil stock into strips with various widths), and the strips with various widths are transited in the pit so as to reduce the tension of the strips with various widths. In this case, the tension of the strip materials of various widths changes when the strip materials reach the pit, the bending degree of the strip materials of different widths in the pit is different due to the change of the tension, and the bending degree of the strip materials on the slitting roller is affected when the bending degree is too large. When the bending degree of the strip material on the slitting roller is too large, the strip material can be rolled out of the proper track, so that the problem that the strip material is higher than the track to be solved is solved. When the strip material rolls out of the corresponding track, the strip material cut by the rolling shear is more and more deviated, and finally, the width of the cut strip material is different, so that the use of the subsequent procedures is influenced.

In conclusion, the situation that the coil stock is bent under the influence of tension in the transmission process of the coil stock is solved.

The limiting device comprises a supporting piece 3 and a limiting column 4, wherein one side of the limiting column 4 is fixed on the rolling shear, and the other side of the limiting column is provided with a column body with a sliding track 5. The upper end of the sliding track 5 is opened, so that the connecting rod 2 can be lifted and separated from the limit of the limit column 4, and the limit disc 1 on the connecting rod 2 can be detached. The limiting column 4 is used for limiting the connecting rod 2, and when the height of the connecting rod 2 is within the limiting range of the limiting column 4, the connecting rod 2 can only move up and down and can not move in other directions. Therefore, the limitation of the connecting rod 2 to the strip materials can be effectively realized, and the strip materials move, so that the sliding track 5 can prevent the connecting rod 2 from bending and inclining along the direction of the strip materials. The arrangement of the sliding track 5 can also ensure that the connecting rod 2 is not influenced in the process of moving up and down.

The support 3 is fixedly connected with the other side (the side without the limit post 4) of the connecting rod 2, the support 3 is an element bearing the gravity of the connecting rod 2 and plays a role of fixing and supporting the connecting rod 2, the slight inclination of the connecting rod 2 has little influence on the use of the device (detailed below), the upper end of the support 3 is square and is convenient to be connected with the connecting rod 2, and the lower part is cylindrical, so that the consumption of materials can be effectively reduced, and the normal movement can be kept.
