Problems solved by technology
Continuous stamping dies have high production efficiency, but continuous stamping dies bury hidden dangers for product stability at the same time of high-speed production. For stamping products, the longer the die, the more projects, the greater the probability of dimensional variation, and the higher the cost of the die.

The invention provides a die structure for bending forming, and belongs to the field of dies. The bottom of a second fixed-distance screw penetrates through an upper fixed plate to be fixedly connected with a first-stage fixed plate, the upper fixing plate is fixedly connected to the upper end of a wedge punch, and the lower end of the wedge punch penetrates through the first-stage fixed plate anda material pressing plate in sequence and extends to the upper part of a forming punch. The bottom inclined surface of the wedge punch corresponds to the side inclined surface of the forming punch, the first-stage fixed plate is connected with the material pressing plate through a first fixed-distance screw, and a bending punch is fixedly connected to the lower end face of the first-stage fixed plate. The bending punch penetrates through the material pressing plate and corresponds to a bending female die, and a workpiece is fixed to the bending female die through the material pressing plate.The bending female die is internally provided with a first elastic part and an unloading block, and the bending female die is fixedly connected with a lower fixed plate. The forming punch is slidablyconnected with the lower fixed plate through a guide plate, and the lower fixed plate is internally provided with a second elastic part which drives the forming punch to move horizontally. According to the die structure for bending forming, the production costs are reduced, and the structure is simple.
Description
technical field [0001] The invention belongs to the field of moulds, and relates to a mold structure for bending and shaping. Background technique [0002] Stamping die is an indispensable process equipment in stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of stamping dies. The level of stamping die design and manufacturing technology largely determines product quality, efficiency and new product development capabilities. The bending and forming of the existing stamping and bending dies are separated, and the corresponding engineering is added for positioning, and the more contact with the die during the bending process, the greater the possibility of product variation. Continuous stamping dies have high production efficiency, but continuous stamping dies bury hidden dangers for product stability at the same time of high-speed producti...
