Machine for detecting mechanical performance of galvanized steel plate, and detection method of machine

Abstract

The invention relates to a machine for detecting the mechanical performance of a galvanized steel plate, and a detection method of the machine. The machine comprises a working frame; fixed locking devices are symmetrically arranged on the inner sides of the front end and the rear end of the working frame; executive operation devices are symmetrically arranged on the outer sides of the front end and the rear end of the working frame; a pressing air cylinder is installed on the inner wall of the upper end of the working frame; the top end of the pressing air cylinder is installed on a pressing fixed plate through a flange; and a working supporting plate is installed between the inner walls of the working frame. The machine can solves the problems that in an existing process of testing the mechanical performance of the galvanized steel plate, the galvanized steel plate needs to be manually conveyed to designated test equipment through existing equipment, the galvanized steel plate needs to be manually fixed by means of a tool, the test curvature of the galvanized steel plate needs to be manually controlled, and the surface of the galvanized steel plate is not effectively protected inthe conveying process, so that the defects such as surface scratches and the like are easily caused, and the galvanized steel plate is instable to fix manually and is poor in firmness.

Description

technical field [0001] The invention relates to the technical field of galvanized steel sheets, in particular to a machine for detecting mechanical properties of galvanized steel sheets and a detection method thereof. Background technique [0002] Galvanized steel sheet has excellent corrosion resistance, paintability, decoration and good formability. It is widely used in construction, household appliances, vehicles and ships, container manufacturing, electromechanical industry, etc., almost involving all fields of clothing, food, housing and transportation. The demand for galvanized steel sheets continues to expand, and the quality control of galvanized steel sheets is also more standardized. At present, galvanized steel sheets need to be tested for mechanical properties before sales, and galvanized steel sheets need to be bent. Observe the galvanized steel sheets after bending. In order to identify the quality of the galvanized steel sheet, but in the process of testing th...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a galvanized steel sheet mechanical performance testing machine and its detection method, which can solve the existing galvanized steel sheet mechanical performance testing process that requires manual delivery of galvanized steel sheets to designated On the test equipment, it is necessary to manually fix the galvanized steel sheet with the help of tools, and it is necessary to manually control the test curvature of the galvanized steel sheet. During the transportation process, there is no effective protection for the surface of the galvanized steel sheet, which may easily cause surface scratches and other defects. Manually fixing the galvanized steel sheet is unstable and has poor reliability, which cannot ensure the stability of the galvanized steel sheet during the bending test. Manually controlling the bending operation of the galvanized steel sheet is complicated, and cannot precisely control the bending degree of the galvanized steel sheet at a specified angle , affect the bending effect of galvanized steel sheet and other problems, can realize the function of mechanized high-precision control of galvanized steel sheet bending test without manual operation, can effectively control the bending accuracy of galvanized steel sheet, and has good stability and easy operation Simple, low labor intensity and high work efficiency
