Data traceability method and production line in a thermoforming production line

Abstract

The invention discloses a data tracing method in a hot-press forming production line, and the hot-press forming production line using the data tracing method. A system is additionally provided with areal-time engraving and marking machine on the basis of original mechanical marking; material pieces before pressing are mechanically marked firstly; after the material pieces are pressed into products, the stroke number of this time is generated; and then, heating technique parameters and pressing technique parameters are stored according to mechanical marking information and the stroke number ofthis time, and the stroke number of this time is printed on the products. On the one hand, each product can be identified, real-time technique data for producing the products are imported into a database; and on the other hand, precise data tracing of each stroke of the products can be conducted, and data support is provided for subsequent processes and product using.

Description

technical field [0001] The invention relates to the technical field of metal rolling, in particular to a data tracing method in a hot pressing forming production line and a hot pressing forming production line using the method. Background technique [0002] In thermoforming production lines, product data traceability has been widely used. The mechanical marking machine before the product is formed can be traced. However, the identification of the products produced in each shift is the same, and can only be traced back to the production date, production equipment, and production personnel. Unique process data during the production of a single product, such as: furnace temperature, heating time, pressing pressure, etc. cannot be traced. [0003] Using barcode or QR code to trace the data of a single product is the most common method, but this method is not applicable in the thermoforming production line. The products produced by the thermoforming production line need to go ...

Problems solved by technology

However, adopting this idea, on the one hand, it is necessary to increase the variable "hook number" and introduce an automatic hook number recognition device, which complicates the control process and increases the cost; The problem is that if the raw material is not processed into a product due to equipment failure, it is difficult to judge whether the process data corresponding to the raw material is imported into the database, and manual intervention is required to delete the data
