Automatic discharging structure of stamping die for doorsill inner plate connecting part

Abstract

The invention discloses an automatic discharging structure of a stamping die for a doorsill inner plate connecting part. The stamping die comprises an upper die, a blank holder die and a lower die. The upper die is provided with an upper insert, and a lower insert corresponding to the upper insert is composed of a middle insert and peripheral inserts arranged in a circle of the periphery of the middle insert. The middle insert is integrally fixed to the upper surface of a boss. The peripheral inserts are fixedly arranged at the edge of the upper end of a middle vertical hole formed in the blank holder die in an inserted mode. The automatic discharging structure is characterized by further comprising a discharging air cylinder transversely fixed to the blank holder die, and a material pushing plate capable of being connected with the shortest side edge of a sheet material to be machined in an abutting mode when a push rod is in a folded state is fixed to the outer end of the push rod of the discharging air cylinder. The automatic discharging structure has the advantage of being ingenious and reasonable in structure, and is capable of automatically discharging materials after stamping is completed and improving the work efficiency of stamping machining.

Description

technical field [0001] The invention belongs to the field of processing tooling for the connecting parts of the inner panel of the threshold of the automobile, and in particular relates to an automatic unloading structure of a stamping die of the connecting part of the inner panel of the threshold. Background technique [0002] The inner panel of the sill panel of the car is a long sheet metal part located at the front and rear door sills in the car body structure. The door sill inner panel connector is a sheet metal part used to connect the door sill inner panel with the side wall in the car body structure, such as the announcement number CN204368020U, the technology named "a car door sill inner panel assembly and automobile" The label in the scheme is "30-rear section of inner panel" (refer to the attached figure in the description figure 1 shown) is the door sill inner panel connector. [0003] At present, the mold used for stamping and forming the inner panel of the do...

Problems solved by technology

[0003] At present, the mold used for stamping and forming the inner panel of the door sill panel of the automobile can only process a single piece at a time, such as figure 1 The door sill inner panel connector with the structure shown is not only inefficient in processing, but also the curved side edge on the upper side of the processed door sill inner panel connector is flat, resulting in low structural strength of the curved side edge
