[0002] Press-fit dies are key equipment in automobile manufacturing used for sheet metal stamping. Their electrical components are typically wired at the die manufacturer according to electrical schematics. However, in current technology, due to the lack of corresponding equipment from die manufacturers to OEMs, the power-on and communication debugging of the press-fit die with the press cannot be performed at the die manufacturer and must be done at the OEM customer's site. This results in lengthy on-site debugging times, and if spare parts fail, procurement is required, further extending the debugging cycle. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the aforementioned technologies by providing an offline debugging device for pressing molds and its usage method.

[0011] Preferably, the programmable logic controller (PLC) has a built-in offline debugging program for the pressing mold, which is exactly the same as that of the OEM.

[0012] Preferably, the bottom of the pressing mold control console is provided with several rollers.

[0013] A method for using an offline debugging device for a pressing mold: After generating the pressing mold, connect the pressing mold to the electrical interface of the pressing mold control console, start the pressing mold control console, select the settings that match the pressing mold through the touch screen interactive device, simulate the press machine signals and press machine control logic of the OEM, and perform offline debugging of the pressing mold.
