Problems solved by technology

[0002] The factory needs to carry out incoming inspection on the purchased sheet. When the quality of the sheet is not up to standard, it will cause bending cracks. Therefore, it will cause endless troubles when the substandard sheet is put into use, so it is necessary to limit the sheet before making parts. Bending test, the existing technology does not have such a mechanical bending test instrument

Abstract

The invention provides a bending testing device for a cold-bending plate. The bending testing device for the cold-bending plate comprises a rack assembly, an oil cylinder 1, and a bending adjustment assembly. The bending testing device for the cold-bending plate is characterized in that the rack assembly comprises a base 2, side plates 3 and a top late 4. The side plates 3 is welded to the base 2.The top plate 4 is welded to the side plates 3. The oil cylinder 1 is fixedly connected with the top plate 4. The bending testing device for the cold-bending plate has the beneficial effects that sufficient bending experiments can be conducted on the plate by the device; the condition of changes of cracks after extreme bending is conducted is observed; and qualification degree of the plate is judged.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a trial folding device for cold-formed sheet materials, which is used for performing limit trial folding operations on purchased sheet materials. Background technique [0002] The factory needs to carry out incoming inspection on the purchased sheet. When the quality of the sheet is not up to standard, it will cause bending cracks. Therefore, it will cause endless troubles when the substandard sheet is put into use, so it is necessary to limit the sheet before making parts. Bending test, the existing technology does not have such an instrument for mechanical bending test. Contents of the invention [0003] The invention provides a trial bending device for cold-formed sheet material. [0004] The purpose of development: This device can conduct sufficient bending experiments on the sheet metal, and judge the qualified degree of the sheet material by observing the change of cracks after ext...
