Description

A separation roller device

technical field

The utility model relates to a separation roller device.

Background technique

High-quality steel strips such as automotive outer plates require special treatment in each process section of cold rolling, which is different from ordinary cold-rolled plates and has a wider width. Therefore, the equipment of the cold rolling plant for the production of automobile outer plates is all wide-band steel production equipment, but the market also needs a small amount of narrow-width steel strips. If wide-band steel equipment is used to produce narrow-width steel strips, the production cost is quite high, so it needs to be installed and split The unit, that is, in the last finishing process of cold rolling, the wide strip is divided into two from the middle to become a narrow strip. The slitting unit can complete the longitudinal division of the strip, but due to the limitation of the slitting production process, its output is far lower than that of the recoiling unit, and a large number of cold rolling and finishing units need the recoiling inspection function, so the The recoiling inspection function and the splitting function are combined on one unit to form a recoil splitting unit. The separation roller device is a key equipment used in the recoil splitting production line. When large-scale conventional production of wide-format strip steel is carried out, the split shear and separation roller device exits the working position, and the production line is used as a recoiling unit; when needed When producing narrow strip steel, the splitting shears and separation roller device are put into operation. The splitting shears conduct equal longitudinal division of the strip steel, and the separation roller device performs horizontal separation of the split strip steel to prevent the inner edge of the two narrow strip steel from Scratches occur, affecting the quality of the strip and damaging the equipment. At this time, the production line is used as a splitting unit.

Conical rolls are mostly used in the current strip longitudinal separation devices, and the separation degree of narrow strips in such devices is related to the taper and reduction of the tapered rolls. This structural form has a serious defect: because the taper of the tapered roller is not adjustable, its separation performance is only suitable for a fixed strip thickness range, and cannot meet the corresponding requirements for the separation effect of strips with different thickness specifications, so its separation effect Generally, the adaptability is poor, and the continuity is not good.

Detailed ways

The utility model relates to the field of metallurgical equipment, in particular to the strip finishing operation, and is a separating roller device suitable for a wide-band steel recoil splitting production line.

Referring to Fig. 1 to Fig. 3, the concrete structure of a kind of separation roller device that the utility model relates to is:

Including the swing frame 3, the lower arc roller 4, the upper pressure roller 1, the reduction box 6, the universal coupling 10, the reduction motor 11, the cylinder 9 and the frame 8; among them,

There is a rotating fulcrum in the middle of the swing frame 3, the swing frame 3 is hinged with the frame 8 through the pin shaft 2, the bottom of the swing frame 3 is connected with the cylinder 9, and the upper pressure roller 1, the lower arc roller 4 and the reduction box 6 are respectively fixed On the swing frame 3, there is a certain distance between the upper pressing roller 1 and the lower arc roller 4, and the size of the interval is determined according to the diameter and the equipment structure of the upper pressing roller 1 and the lower arc roller 4. As shown in Figure 1, the effect of this spacing is: first, when putting into separation work, the lower curved roller 4 protrudes to separate the strip, while the lower surface of the upper pressing roller 1 is level with the operation line, so as to maintain the elevation of the operation line, The role of stabilizing the strip steel; the second is that when the separation work is not put into use, the distance is convenient for the strip to pass through, the upper pressure roller 1 and the lower arc roller 4 do not touch the strip steel, and the reduction box 6 is connected with the reduction gear through the universal coupling 10 Motor 11 is connected. A pair of air cylinders 9 drive the swing frame 3 to rotate around the pin shaft 2 to quickly switch between the two working conditions of whether the separation roller device is put into operation or not.

The upper pressure roller 1 in the utility model can specifically be a steel-based rubber-lined roller, and its function is to stabilize the separation effect of the strip steel 7 after passing through the lower arc roller 4, while maintaining the operation line of the strip steel 7 after passing through the separation roller device. The elevation does not change. The lower arc roller 4 can specifically be a convexity-adjustable rubber-lined roller. The two ends of the mandrel are flat shafts, and the middle part of the mandrel is bent into an arc. Install a rubber-lined roller with the same curvature as the mandrel. The convexity of the curved roll and its separation effect on the strip change with the different swing angles of the mandrel. As shown in FIG. 3 , the chord height of the arc-shaped mandrel is denoted as s, and the maximum convexity of the lower arc-shaped roller 4 depends on the chord height s and the length of the roll surface. The lower arc roller 4 is the prior art, and the convexity of the lower arc roller 4 can be adjusted by the angle of the rotating mandrel, and the convexity can be adjusted from 1 to the maximum chord height s by rotating 0-180°. For a specific arc As far as the shape roller is concerned, the chord height s is determined, that is to say, its maximum convexity is certain. The determination of the convexity should consider factors such as the thickness and material of the strip steel, and adjust it according to the separation effect of the strip steel.

One end of the lower arc roller 4 in the utility model can be fixed on the operating side bearing seat 12 on the swing frame 3 through the joint bearing 13, and the other end can be fixed on the transmission side bearing seat on the swing frame 3 through the worm wheel 15 and the worm screw 16. 14 on. Rotating the worm screw 16, the lower curved roller 4 can rotate around the centerlines of the bearing seats on both sides, thereby adjusting the convexity of the lower curved roller 4.

The worm screw 16 in the utility model can specifically be connected with the reduction box 6 through the elastic coupling 5 . The reduction box 6 is a vertical input and output shaft. Due to the large rotation range of the swing frame 3, the reduction motor 11 drives the reduction box 6 through the universal coupling 10 with a large allowable angle and expansion and contraction, and then rotates the worm 16 and the worm wheel 15. , drives the lower arc roller 4 to rotate, and realizes the continuous electric adjustment of the convexity of the lower arc roller 4 .

There is a certain distance between the upper pressure roller 1 and the lower arc roller 4. When the piston rods of the pair of cylinders 9 are retracted at the same time, the swing frame is placed at station 1. At this time, the upper pressure roller 1 and the lower arc roller 4 , located at the dotted line position in Figure 1, the lower arc roller 4 is located below the operating line of the unit, and the upper pressing roller 1 is higher than the operating line of the unit, neither of which touches the strip 7. It is suitable for the separation roller device not to be used when the strip 7 is not divided. Operating conditions, such as the smooth passing of the strip steel 7 during belt threading and rewinding; when the piston rod of the cylinder 9 is extended at the same time, the swing frame is located at the second station, and the swing frame 3 is located at the position shown in Figure 1. At this time, the separation The roller device is put into operation, the lower curved roller 4 is higher than the working line of the unit, and the narrow strip steel 7 on both sides runs along the corresponding convexity on both sides of the lower curved roller 4 under a certain tension and pressure, and separates to both sides. The upper pressure roller 1 presses down to stabilize the separation effect of the strip steel 7 after the curved roller.
