Problems solved by technology

Therefore, the disadvantage of this measurement method is that the measuring tools cannot be used universally, and the management is inconvenient. The standard template is made of metal, which takes up space for storage, increases the processing and management costs, cannot be recycled, and is a great waste of resources; Based on the experience of the operator, the accuracy of the measurement results is not high

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Marks in the figure: ruler frame 1; data line interface 2; data line 3; intelligent control box 4; locking screw 5; telescopic tube 6; roller 7; grating displacement sensor 8; movable rod 8.1; compression spring 8.2; 8.3.

[0020] The theoretical basis of the present invention is the principle of "three points form a circle", see attached figure 1 : The radius of the circle is R, the radius of the inscribed circle is r, in the right triangle OEO 2 In, OE=R-H, EO 2 =L,OO 2 =R-r, according to the Pythagorean theorem:

[0021] (R-r) 2 =(R-H) 2 +L 2

[0022] Deduce: R=(H 2 +L 2 -r 2 ) / 2(H-r)

[0023] That is, in a circle or arc, the chord length is known, and the measurement radius R and diameter ? can be calculated by measuring the chord height H.

[0024] According to the above theoretical design, the technical idea of ​​measuring the radius o...

Abstract

The invention relates to a roll bending forming curvature radius measuring device of a plate coiling machine. The roll bending forming curvature radius measuring device comprises a ruler frame and an intelligent control box, wherein a data wire interface is arranged on the ruler frame, and in addition, the ruler frame is connected with the intelligent control box through the interface via a data wire. The roll bending forming curvature radius measuring device is characterized in that the ruler frame is a cross-shaped hollow pipe, a telescopic pipe is inserted and connected into left and right horizontal hollow pipes of the ruler frame, the outer end of the telescopic pipe is provided with a rolling wheel, the telescopic is fixed by a locking screw, one grating displacement sensor is fixedly arranged in the telescopic pipe, a moving rod of the grating displacement sensor is tightly abutted against the vertical hollow pipe wall of the ruler frame, the other grating displacement sensor is also fixedly arranged in the vertical hollow pipe, and the end head of a moving rod of the other grating displacement sensor is provided with a rolling wheel. The roll bending forming curvature radius measuring device has the advantages that the intelligent control integration technology is adopted, the measuring procedure is simplified, the measuring value is intuitive and clear, and the measurement precision is high; the chord length of the measuring device is adjustable, the measuring range is enlarged, the use is convenient, and the work efficiency is high; and raw materials are saved, the manufacture cost is reduced, and the measuring tool management is convenient.

Description

technical field [0001] The invention relates to a measuring device for the bending radius of curvature of a plate rolling machine, in particular to a measuring device for measuring the radius of curvature of a plate rolling machine by using an intelligent control electronic integration technology. Background technique [0002] At present, the method of manual measurement is widely used in the bending process of the plate rolling machine, that is, the standard sample is used to measure the radius of curvature of the plate by a ruler. Due to the limitation of the use of the standard sample, each roll bending The radius of curvature of the shape must be measured with a corresponding standard template. Therefore, the disadvantage of this measurement method is that the measuring tools cannot be used universally, and the management is inconvenient. The standard template is made of metal, which takes up space for storage, increases the processing and management costs, cannot be rec...
