The utility model discloses a kind of automobile body side structure, it is related to automobile parts technical field, including side wall, the inner wall of side wall is fixedly connected with reinforcing rib, the inner wall of side wall is installed with sound insulation cotton, the side wall of side wall is fixedly connected with guide rail.The utility model is provided with side wall, reinforcing rib and sound insulation cotton, by the reinforcing rib of honeycomb shape being set, honeycomb reinforcing rib is supported by grid element mutually, the tensile force, shear force or bending force received is dispersed to multiple grid nodes, and the mechanical transmission path of " multiple point stress - overall bearing " is formed, to improve shear strength, strengthen the protection function of device, in the flexible matrix of using sound insulation cotton, the vibration transmission of side wall can be weakened by damping effect, metal component vibration can be blocked by solid conduction, avoid noise transmission into cabin to provide tranquil cabin environment for driver and passenger.

The application discloses a kind of based on low temperature embrittlement cooperates prefabricated mark guide plate stamping equipment, including base and the shelf plate of being movably arranged on base, the holding module for being clamped and positioning outside the processing area of tensioning the plate to be processed of outside the plate to be processed is arranged between the base and shelf plate, and the groove prefabricated module for processing V-shaped guide groove to outside the plate to be processed preset fracture zone, the low-temperature cooling module for the plate after being processed by groove prefabricated module is arranged on the side of base, to reduce the temperature of plate and maintain low-temperature atmosphere by being used for rapid cooling, and the control cabinet for being respectively communicated connection control with holding module, groove prefabricated module and low-temperature cooling module.The application solves the problem that traditional stamping process handles high-strength alloy plate and the outer ring component of difficult deformation material, because prefabricated mark processing, low-temperature treatment and stamping forming link discrete layout lead to parameter matching, low-temperature embrittlement uncontrollable, difficult to realize the problem of accurate control of fracture surface quality.
