Description

Stamping die for automobile longitudinal beam reinforcing plate Technical Field The utility model relates to the technical field of production of automobile longitudinal beam reinforcing plates, in particular to an automobile longitudinal beam reinforcing plate stamping die. Background The automobile longitudinal beam reinforcing plate is an important part in the automobile body structure, is generally used for enhancing the rigidity and strength of the automobile body, can effectively protect passengers especially in the event of a collision of the automobile, is generally a metal plate with certain strength and rigidity and is arranged on the front and rear longitudinal beams of the automobile, and in summary, is an important component of the passive safety system of the automobile and provides additional protection for the passengers in the event of an accident by enhancing the rigidity and strength of the automobile body. Through retrieval, the utility model patent with the patent publication number of CN221336175U discloses a stamping die for an automobile longitudinal beam outer plate reinforcing part, which comprises a male die and a female die, and further comprises a base box, wherein the base box is in sliding connection with the female die, a sliding groove is formed in the base box, a plurality of supporting mechanisms are connected in the sliding groove in a sliding manner and used for elastically supporting the female die, the male die is connected with a fixing assembly, the fixing assembly is used for connecting and fixing the male die and the stamping mechanism, the base box is connected with a buffer assembly, and when the fixing assembly drives the male die to press down, the buffer assembly can slow down the instant acceleration when the male die falls. According to the stamping die for the automobile longitudinal beam outer plate reinforcing piece, the male die is fixedly connected with the stamping mechanism through the fixing component, when the male die falls, the buffer component can slow down the instant acceleration of the falling male die, and the deformation of the automobile longitudinal beam outer plate reinforcing piece caused by overlarge impact force between the male die and the female die is avoided. However, in the above design, when the male die falls, the buffer assembly can slow down the instantaneous acceleration of the male die falling, so as to avoid the overlarge impact force between the male die and the female die, however, once the die is manufactured, the shape and the size of the die are fixed, if the product design needs to be changed, a new die is usually required to be redesigned and manufactured, and when the dies with different sizes are punched, the dies need to be replaced, so that work is stopped, and for this reason, we propose a stamping die for the automobile longitudinal beam reinforcing plate to solve the above problems. Disclosure of utility model The utility model aims to provide a stamping die for a longitudinal beam reinforcing plate of an automobile, which is used for solving the problems in the background art. The stamping die for the automobile longitudinal beam reinforcing plate is characterized in that the inner wall of the supporting box is connected with a rotating rod in a sliding mode, the front face of the rotating rod is connected with a rotating valve, the outer surface of the rotating rod is sleeved with supporting columns, the outer surfaces of the supporting columns are connected with a plurality of stamping blocks, the outer surfaces of the rotating rod are sleeved with gear blocks, the inner wall of the supporting box is connected with a gear set, the outer surface of the rotating rod is connected with a limiting column, and the back face of the rotating rod is connected with a limiting sheet. The front of the workbench is connected with a control board, and a group of supporting legs are arranged on the bottom surface of the workbench. The upper surface of the supporting box is connected with a plurality of damping rods, and the outer surface of each damping rod is sleeved with a reset spring. The outer surfaces of the damping rods are connected with a connecting plate in a sliding mode, and the bottom surface of the connecting plate is connected with the bottom surface of the reset spring. The upper surface of the workbench is connected with two air cylinders, the output ends of each air cylinder are sleeved with buffer springs, and the output ends of the two air cylinders are connected with a supporting plate together. Compared with the prior art, the utility model has the beneficial effects that: The utility model ensures that the flat rotating rod can rotate by arranging the pulling rotating valve 5, thereby ensuring that various dies can be replaced, adapting to the product requirements of different sizes or shapes to a certain extent without completely redesigning and manufacturing new dies, avoiding the die replacement
