Description

Slitting line metal strip anti-abrasion device based on hydraulic control

Technical Field

The utility model relates to a indulge trimming processing field specifically is indulge trimming metal strip material abrasionproof decreases device based on hydraulic control.

Background

The slitting line is also used for slitting coils such as galvanized iron, silicon steel sheets, stainless steel strips, aluminum strips, steel strips and the like by a slitting machine set. The metal coil stock is cut into strip stock with various required widths, and then the strip stock is coiled for the next working procedure. The longitudinal shearing unit is used for uncoiling, cutting, slitting, tensioning and coiling a metal coil stock. Thereby completing the cutting of one large metal coil into multiple coils of different widths. Because the metal coil is uncoiled from a large coil to a small coil, the transmission speed of the metal coil is changed from high speed to low speed under the condition that the rotating speed of the uncoiler is unchanged.

There are problems with placing the metal coil on the ground. In the long-time metal coil processing process, the metal coil rubs the ground, so that the ground becomes rough, and then the ground generates abrasion, scratches and the like on the surface of the metal coil in the subsequent processing process. And after the metal coil stock is cut into a plurality of strip stocks by the slitting mill, the phenomenon that the metal strip stocks are lifted to be positioned above another strip stock due to the change of the tension force in the storage process can also exist, so that the phenomenon that the two strip stocks rub with each other can occur in the continuous transmission process of the two strip stocks, the abrasion condition of the strip stocks can be generated, and the subsequent processing procedures can be influenced.

The using method is detailed as follows:

when the slitting machine set works, the pressure block 10 can be placed on the supporting plate 9 to ensure that the strip does not fall down to contact the ground. If it is desired to maximize the height of the device, it is only necessary to continue to add the pressure block 10. And the strip is in contact with the U-shaped table 13 during this process, and is thus able to move normally. When the device reaches the maximum value, the strip deposit length still can produce the production of strip material condition of taking off constantly, the influence of the condition of taking off to the strip material is not big, the vibrations that only can produce the slitting unit can conduct on this device along the strip material for the U type platform 13 vibrations of this device top, and the bolt of control bottom plate 15 bottom, thereby the flexible volume of control spring 14 reaches absorbing effect with this, and guarantee the leakproofness between interior piston rod 3 and the outer piston rod 2. And air inlet duct 4, inlet port 7 etc. set up the rear side at the strip conveying, can reduce pollutants such as iron fillings like this and get into air inlet duct 4, the change of air screen 16 has been reduced to the greater extent to the condition of inlet port 7. When the longitudinal shearing unit is about to finish working, the number of the pressure blocks 10 is reduced, so that the height of the device is reduced, and the condition that the strip is ejected out of the device due to the fact that the tension is reduced. Thereby requiring a reduction in the number of pressure blocks 10 immediately after the slitting line has finished processing.

The whole lifting process is shown in the attached figure 6 of the specification, when the device does not work, as shown in the attached figure 6A of the specification, the bottom plate 15 is in contact with the inner piston rod and the outer piston rod, when the device is used, the pressure block 10 is placed on the supporting plate 9, and when the tension of the fed noodles is reduced, the supporting device is lifted, so that the noodles are straightened. As shown in the figure 6B of the attached figure, because the strip has large gravity, the inner piston and the outer piston can support the strip in the lifting process. When the outer piston rod 2 moves to the maximum extent, as shown in fig. 6C of the attached drawing, the outer piston rod 2 does not move, and only the inner piston rod 3 supports the strip. When the inner piston rod 3 moves to the maximum, as shown in D in figure 6 of the specification, the strip material has two conditions, as shown in figure 7 of the specification, wherein the strip material is in a straight state in figure A, and the strip material has a certain bending degree in figure B, and the device has the best condition as shown in A in figure 7 of the specification, wherein the abrasion of the strip material is minimum, and as shown in B in figure 7 of the specification, the strip materials can be abraded mutually.
