2. Description of the Related Art In a steel strip processing line, both edges of a steel strip are trimmed in order to remove defective portions on both edges and to meet user's requirements for each size width. At this time, burrs or burrs are generated on the cut surface, scratches are put on each roll surface while traveling on the processing line, and the scratches are transferred to the steel strip, or after cutting into a sheet shape in a later process. When the conveying direction is perpendicular to the sheet passing direction of the processing line, the steel strip itself is also flawed.

However, these conventional techniques are still not perfect and have problems. For example, in Japanese Utility Model Laid-Open No. 62-150021, in the case of a thin steel strip, since the steel strip itself has no rigidity,
There is a problem in that a strip supporting device is newly required in the vicinity of the deburring device, and when the shape of the steel strip is wavy in the traveling direction, the cutting amount changes and the cutting is performed excessively. Further, in Japanese Patent Laid-Open No. 2-224918, since the hydraulic cylinder is used, it is pressed down at a constant pressure regardless of the amount (height) of burrs or burrs. Therefore, the precision after crushing is unstable. The present invention solves the above problems, and an object of the present invention is to provide a deburring device for a side-trimmed steel strip edge.

Two pairs of rolls consisting of a roll and a moving roll are provided, a spring for appropriately adjusting the rolling force is provided on the moving roll, and the chocks of the moving roll are supported by a sliding mechanism, and the moving roll is retracted. At times, it is characterized by an air cylinder that can be moved.

The burrs removing device of the present invention is a mechanism for crushing the burrs of the steel strip after trimming by the front and back rolls. Since the self-weight of the movable part is supported by the low resistance slide bearing, the effect of the self-weight is eliminated. Since it can be almost ignored, the spring reduction force can be made equal to the reduction force according to the amount of burrs, and stable plate thickness accuracy of both edges after crushing can be obtained. As shown in FIG. 2, in the experiments conducted by the present inventors, the sliding resistance of a moving roll having a roll diameter of φ80 × 100 l was 1 kg, which can be almost ignored.

That is, as shown in FIG. 5, with a constant rolling force, it is not possible to follow the variable amount of burrs due to changes in the trimming state, and a rolling force excess / deficiency region occurs. However, according to the present invention, as shown in FIG. It is possible to obtain an approximate property to the rolling force required for removing burrs. In the figure, i: necessary reduction force for removing burrs, b: reduction force by hydraulic cylinder, c: insufficient reduction force region, d: excess reduction force region, e: reduction force by spring, f: air cylinder and sliding part Shows the specific resistance of.

1 is a front view showing an embodiment of the present invention, FIG. 2 is a sectional view in the vertical direction of a roll portion, and FIG. 3 is a sectional view in the horizontal direction of a roll portion.
As shown in FIG. 1, the burrs on both edges of the steel strip 6 are crushed by the fixed rolls 1 and the movable rolls 2 on the front and back sides. The moving roll 2 is supported by a chock 8, the chock 8 is supported by a sliding portion 5, and the sliding portion 5 is arranged substantially on the same axis as the load point 7.

A sliding bearing is used for the sliding portion so as to have a low resistance. Two slide bearings are placed above and below the chock to prevent the chock from shaking. The moving roll 2 is opened and closed by a spring 4 in the rolling direction, and is opened by an air cylinder 3 when the main body is retracted when a welding point is passed or when the plate width is changed. The spring 4 and the air cylinder 3 are arranged substantially on the same core as the load point 7, and no unbalanced load is generated.

In order to reduce the rotation resistance of the roll, it is preferable that the roll has a diameter as small as possible (about 80) and that only the roll rotates. Further, the material of the roll is preferably super-hard or equivalent in consideration of wear resistance at high speed passage. The reduction force of the spring according to the present invention has a plate thickness t of 0.1 to 0.4.
In the case of thin steel strip of mm, 10-15kg by various tests
A very slight degree is optimal. In the processing line, 200 in a thin steel strip with a plate thickness of 0.1 to 0.4 mm
It is possible to automatically reduce the steel strip while it is threading at mpm, and it is possible to produce a steel strip without burrs even after high-speed rolling at 1200 mpm.

EFFECTS OF THE INVENTION According to the present invention, (1) because of the spring reduction method, the pressure-bonding force varies depending on the amount of burrs or burrs, and consequently the amount and width after crushing of burrs or burrs are stabilized. It is possible. (2) Since the sliding resistance is small,
It can follow the vibration of steel strip at high speed. (3) Since it is a direct-acting type, the rolling force does not change even if the load point deviates slightly. (4) It can be used regardless of whether the burrs are on the front or back of the steel sheet.
(5) Since it is an open system using an air cylinder, it is possible to automate the reduction of pressure during running.
