Abstract

PURPOSE:To verify a tension meter without removing a load cell by setting a hydraulic cylinder and a verification load cell on a detachably mounted support frame and comparing output values of the verification load cell and output values of the load cell set on a tension roll. CONSTITUTION:Tension values of a steel sheet 1 being on a passage through a cold rolling mill is detected by a tension meter consisting of a tension roll 2 and load cells 3. A support frame 4 is detachably mounted on the housing of a stand of the cold rolling mill and the central part of the frame 4 is provided with a hydraulic cylinder 5 and a verification load cell 6. The cylinder 5 is actuated to bring an attachment 7 contact with the tension roll 2 and to give a concentrated load, so that a tension value is properly added to the two load cells 3 installed under the roll 2. In that method, the output value of the verification load cell 6 is compared with that of the load cells 3 of the tension meter to perform the verification.

(Prior art and problems to be solved) In actual equipment such as cold rolling mills, continuous annealing lines, continuous galvanizing lines, etc., tension rolls are installed for tension control. A tension meter is provided. Since the tension meter is provided to accurately detect the tension of the workpiece or material to be processed and use it for tension control, it is necessary to accurately test the load cell provided at the bottom of the tension roll.

Conventionally, to test this tension meter, a method has been used in which the load cell provided on the tension roll is removed and the accuracy of only the load cell itself is checked using a compression tester or the like. However, this method had the following drawbacks.

That is, (1) it takes a lot of time and effort to remove the load cell from the tension meter. ■Normally, two tension meters are installed at the bottom of the tension roll, and there may be a discrepancy in the mechanical positional relationship between the tension roll and each load cell. In this case, even if only the load cell is tested, This does not mean that the tension meter has been accurately verified, and verification becomes impossible.

(Means for Solving the Problems) In order to achieve the above object, the present inventor proposed that although distributed loads are applied to the load cells (usually two) of a tension meter in actual operation, they are concentrated on each load cell during verification. We found that even if a load is applied, accurate verification is possible if we understand the relationship with the distributed load (i.e., tension value), and further research was conducted on a removable installation method for the verification device1. This invention has been made.

In the present invention, in order to test the tension meter without removing the load cell 3, the support frame 4 is first removably installed in the housing (not shown) of the stand of the cold rolling mill. A hydraulic cylinder 5 and a verification load cell 6 are provided in the center of the support frame 4. A manual hydraulic pump (not shown) is connected to the hydraulic cylinder 5 via a hose 8, and it is possible to apply an arbitrary load, that is, a tension value.
By attaching an attachment 7 coated with copper, for example, to the tip of the tension roll 2, it is possible to contact the tension roll 2 and apply a load without damaging the tension roll 2. In addition, although the steel plate 1 is shown in a threaded state in the figure, it goes without saying that the steel plate 1 is removed during the inspection.

The verification device having the above configuration installs the support frame 4 on the frame of the stand of a cold rolling mill, and then operates the hydraulic cylinder 5 to bring the attachment 7 into contact with the tension roll 2 to apply a concentrated load to the tension roll. 2
Appropriate tension values are added to the two load cells 3 installed below. The test load cell output value at that time is compared with the load cell output value of the tension meter to perform the test.

Second, although a distributed load is applied to the load cell 3 of the tension meter in actual operation, a concentrated load is applied during verification, but the relationship between the tension value and the concentrated load value is Since it can be easily grasped from the angle, there is no practical problem as long as the support frame is installed so that the concentrated load is in the vertical direction.
