Product Introduction

Train Door Panel Shaping Press is a calibration equipment used for train (including high speed railroad, moving train, common speed train, etc.) door panels when deformation occurs in the process of manufacturing or repairing.Its core role is to restore the designed shape and dimensional accuracy of the deformed door panel by applying controlled pressure to ensure smooth door opening and closing, sealing and appearance quality.

Core Functions and Application Scenarios

Main Function: Correcting door panels' depression, bending and twisting caused by stamping rebound, transportation collision, long-term use or welding deformation (e.g., deformation after assembling the door skeleton and the skin).

Application Scenario: Manufacturing: After the door is stamped and molded, the shape deviation is caused by the elastic return of the material (rebound).rebound) leads to shape deviation, which needs to be corrected by the shaping press;

Maintenance: in vehicle sections or maintenance bases, doors are repaired due to deformation caused by accidents (such as scratches), aging or fatigue;

Special requirements: door shaping for lightweight materials such as aluminum alloy, stainless steel, etc. (the ductility and brittleness of the material need to be taken into account).
