Problems solved by technology

In addition, due to the needs of the development of industry technology, many studies on plastic processing of metal sheets have been carried out in universities and research institutes. In these research work, a single sheet is often used as the research object, and there is also a need for bending measurement after deformation of the sheet, but at present There is no corresponding testing instrument

Embodiment 1

[0068] A dial indicator with a range of 20mm is selected, and the length of the support rod is 10mm smaller than the free length of the measuring rod of the dial indicator. The ring gear guide rail 4 is installed on the dial dial with the interference fit of P7 / h6. The modulus of the rack part of the opposing ring gear 7 is 0.3 mm, and the length of the rack segment is 16 mm. The pinion 9 has a module of 0.3mm and 36 teeth. The initial opening angle of the support rod 3 is 20°, that is, the minimum opening angle of the support rod 3 is 20°. At this time, the opening degree pointer 6 points to the opening degree dial 8 to mark the scale 0. The maximum angle at which the support rod 3 can be opened during measurement is 50°. At this time, the opening degree pointer 6 points to the opening degree dial 8 to mark the scale 3, and the opening degree pointer 6 rotates at an angle of 15°. According to the range of the opening angle of the support rod 3, the opening degree dial mark ...

Abstract

The invention discloses a device for quickly measuring the bending degree of a plate. The device comprises a conventional dial indicator and an opening degree part arranged on the dial indicator. Theopening degree part comprises a gear ring which is arranged on the periphery of the dial indicator disc and rotates around the dial indicator disc. The gear ring is semicircular and located on the left side and the right side of the dial indicator disc respectively. The top ends of the gear rings on the left side and the right side are respectively provided with a single-side rack which is meshedwith the pinion to enable the gear rings on the left side and the right side to synchronously and oppositely rotate; a supporting rod with a certain inclination angle is fixedly arranged at the bottomend of the gear ring; according to the plate bending curvature measuring device, the universal dial indicator is used as a main body for transformation, the device is simple. The measurement is convenient and quick. The plate bending curvature measuring device is suitable for occasions where the plate bending curvature needs to be quickly obtained.

Description

technical field [0001] The invention relates to a device for measuring the bending degree of a plate, which belongs to the field of metal plate detection. Background technique [0002] During the plastic processing of metal sheets, sheet metal bending often occurs due to uneven plastic deformation, such as head and tail bending after rolling of medium and thick plates, instability waves after deformation of thin plates, etc. The severity of these bends has a significant impact on the subsequent processing of the plate, such as the straightening process of the plate. Therefore, it is necessary to measure the bending of the plate. On the one hand, it can be used as a feedback correction for the current processing procedure, and on the other hand, it can be used as the original parameter for the process setting of the subsequent process. [0003] At present, in the production of medium and thick plates, the bending measurement is only done manually during the initial equipment...
