Abstract

DC60 (04/01/53) in the process of targeted hammering for crack determination. Incoming unit 101 receives the deformation value of the target mold to be measured into the target punching to determine. crack formation and used as the target data for deciding crack formation using the geometry change measurement unit 8 for the period from the start of hammering to the end of hammering and receiving conditions. In productions in which at least a component is the scroll velocity that would normally be derived from an incoming measurement, the reject unit 102 sorts a reference that determines the minimum value of the difference between the production conditions. of reference data extracted from storage 104 and the production conditions of target data for Judging the occurrence of cracks as comparative data, Judging Unit 103 will compare the replacement. Shapes in the comparative data extracted by sorting unit 102 and transformations in the data. The goal is to judge the occurrence of cracks and to determine the occurrence of cracks in the hammered product if the maximum value of The difference is not less than the predefined value. With the advantages of such a configuration, cracks can be judged which are likely to occur in the process of hammering of various metal materials, such as steel-based materials, non-metallic-based materials and Accurate stacking products

Disclaimer (all) which will not appear on the advertisement page. : ------ 27/11/2017 ------ (OCR) Page 1 of 5 pages. 1. Method for determining cracks in metal stamped products, which determines the occurrence of cracks in Prepared metal products that use punches and dies By using the strain gauge, which somehow measures the strain of the puncher and mold. At least one is selected as the target mold to be measured and the storage unit which stores the strain value of the target mold to be measured over a period of time. All or part of the duration from the beginning of the hammer to the end of the hammering. And the manufacturing condition in which there is at least a component, the scroll speed compared to the It has been hammered a number of which no cracks have formed inside as a reference. Method which consists of Admission process, which takes the target mold strain that will be measured into the hammering. Targets to judge the occurrence of cracks and to be used as the target data for cracking judgment. A unit of measure of stress during the entire period or part of the period since the start of Hammering until the end of hammering And accept manufacturing conditions which contain at least the following components: Scroll speed A separation procedure that extracts data that satisfies pre-defined conditions from the data. Such reference is for comparative purposes, subject to the manufacturing conditions of the selected reference. Detached from the storage unit and adhere to the production conditions of the target data for judgment. And a judgment process which compared the comparative stress and the stress in the Target data to judge the occurrence of cracks and If the conditions that were set in advance were met, Judged that there was a crack in the product that was nailed. 2. Method for determining the occurrence of cracks in hammer metal products according to claim 1, where the conditions for Such production has at least an additional component in addition to sliding speed. One of them is production time, ambient temperature, humidity, clamping force of the pre-formed sheet, part number, information about the location of the processing on the pre-formed sheet. Figure that can be traced from material batch number, workpiece pulling power, workpiece yield strength, workpiece uniform clamping quantity and workpiece thickness ------------
