Abstract

The invention discloses a high-precision punch forming die for a ceiling crossbeam in a bullet train carriage. The high-precision punch forming die comprises a bottom plate and further comprises an ejection structure facilitating part taking, a fixing structure preventing a workpiece from deviating and a positioning structure guaranteeing normal work of a device, two supporting legs are arranged on each of the two sides of the top end of the bottom plate, and a supporting plate is arranged at the top ends of the supporting legs. A lower die base is installed in the middle of the top end of thesupporting plate, side plates are installed in the positions, on the two sides of the lower die base, of the top end of the supporting plate, an empty groove is formed in the center of the bottom endof the supporting plate, the ejection structure is arranged in the empty groove, two third air cylinders are arranged in the position, on one side of each side plate, of the top end of the supportingplate, and top plates are mounted at the top ends of the third air cylinders. A first air cylinder is started to work, thus a transverse plate can be pushed to move, an ejector rod moves upwards, anauxiliary spring deforms till the ejector rod ejects out a machined part, and the structure is beneficial to relieving the burden of workers.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a high-precision stamping and forming mold for ceiling beams in motor vehicle compartments. Background technique [0002] Stamping die is a special process equipment for processing materials into parts. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. And the high-precision stamping and forming mold of the ceiling beam in the existing motor car compartment also has many deficiencies. [0003] First, the traditional beam high-precision stamping mold does not have the function of precise positioning, and the long-term working device is prone to deviation, resulting in unqualified production quality; [0004] Second, the traditional beam high-precision stamping mold does not have a fixed function, which makes it easy for the wo...
