Punching die capable of automatically leveling and machining inclined plane and machining method thereof

Abstract

The invention relates to a punching die capable of automatically leveling and machining an inclined plane. The punching die comprises an upper die and a lower die, a lower die plate is arranged on thelower die, and a profiling positioning block is arranged on the lower die plate; the lower portion of the end, deviating from the side surface to be punched, of the profiling positioning block is hinged to the lower die plate, a rotating arm and a mounting base are arranged on the lower die plate, and the rotating arm is located at one side of the to-be-punched side surface of the profiling positioning block; a top plate is arranged at one end of the rotating arm, a punching female die is arranged on the profiling positioning block, and a punching punch and an upper reverse ejection column are arranged on the upper die; the upper reverse ejection column is connected with the upper die through a first elastic assembly, and a profiling pressure plate is also arranged on the upper die and isconnected with the upper die through a second elastic assembly. According to the present invention, by overturning to flat the punching position and then punching, a conventional wedge structure is replaced, the die has the advantages that a knife edge is not easily damaged, the punching burrs are few, and the precision requirement is low and the like and enables the workpiece quality to be improved, the additional power is not needed for assisting turnover during the turnover process, and the die is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field, and more specifically relates to a punching die for automatically leveling a processing inclined surface and a processing method thereof. Background technique [0002] In the car seat frame series parts, because the shape and surface of the seat basin parts are irregular, and there are many locking and positioning holes in the whole part, punch holes on many slopes or special-shaped surfaces, and punch holes on the normal side It is necessary to use the inclined wedge to swing out the corresponding angle for punching. When the angled punching is used, when the gap between the inclined wedge and the die is not in place, it will lead to large punching holes, the edge of the lower die is easy to be damaged, and there is no need to align the workpiece for punching. The structure design of the hole die is complex, and the punching speed of the die PPM cannot be increased, which leads to low production efficiency...

[0002] In the car seat frame series parts, because the shape and surface of the seat basin parts are irregular, and there are many locking and positioning holes in the whole part, punch holes on many slopes or special-shaped surfaces, and punch holes on the normal side It is necessary to use the inclined wedge to swing out the corresponding angle for punching. When the angled punching is used, when the gap between the inclined wedge and the die is not in place, it will lead to large punching holes, the edge of the lower die is easy to be damaged, and there is no need to align the workpiece for punching. The structure design of the hole die is complicated, and the punching speed of the die PPM cannot be increased, etc., which leads to low production efficiency and a decline in the quality of the workpiece, etc.
