Abstract

PURPOSE:To measure accurately and efficiently the true curve of a die steel by providing plural supporting tables for die steel furnished with a measuring instrument, freely capable of transversing and elevating. CONSTITUTION:The die steel 1 carried in by a supporting table 2 for transfer is supported by the plural supporting tables 3 which are furnished with the measuring instrument 8 and freely capable of elevating to measure the curve. The supporting stands 3 are supported by a elevating device 4, on which a measuring dolly 6 is placed and fixed with a stopper 7 at the usual time. For the measurement, when the die steel 1 is supported by means of elevating the plural supporting stands 3 and the stopper 7 is released by an air cylinder, etc., the dolly 6 is made freely transversal and a gravitational friction force of the die steel 1 is released, then the true curve is made remarkable. The curve at this time is measured by a curve measuring instrument 8 of non-contact type like a laser, etc.

[Problems to be Solved by the Invention] However, since the conventional measuring device is configured as described above, frictional force due to the weight of the section steel acts between the section steel and the support base, causing the section steel to move laterally. Deforms elastically. For this reason, if the shaped steel is simply placed on a support stand, the true amount of bending cannot be obtained. In addition, when high measurement accuracy is required, since a water system is used, the measurement requires a long time and the working ratio is reduced.1 The present invention solves the above problems and allows true bending of the section steel. The purpose of this paper is to propose an apparatus for detecting bending of section steel that can be measured accurately and efficiently.

[Function] The shape steel bend detection device of the present invention supports the shape steel by a plurality of laterally movable support stands and detects the bend of the shape steel by the bend detection means, so that the elasticity of the shape steel is detected. The deformation is released by lateral movement of the supports and the true bend can be measured. Further, by making the support stand movable up and down, the support stand can be raised when measuring the bending of the shaped steel, and lowered when not measuring (for example, when transporting the shaped steel), thereby improving work efficiency.
