Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bending and stamping, and particularly relates to an upward forming stamping die. Background Art
[0002] In the field of stamping parts processing, bending stamping parts is a common process, which mainly relies on the stamping die to apply external force to the stamping parts to cause bending deformation, thereby obtaining the required fillet and bending angle.
[0003] In conventional stamping dies, when a stamped part needs to be bent 90 degrees, it is usually necessary to first bend it 45 degrees and then bend the remaining 45 degrees. This is done in two separate dies, minimizing the risk of material tipping, distortion, or dimensional errors. However, this method increases the cost of the die and processing time.

[0025] Working process: In the natural state, the bottom of the forming part 5 is placed on the bottom wall of the movable groove 11; when working, the forming part 5 first contacts the product, and is pressed against the side wall of the movable groove 11 under the thrust of the product. At this time, the direction in which the forming part 5 punches the product is not vertical, and the forming part 5 gradually bends the product upward along this direction until the product is bent 45 degrees; then the forming part 5 is pressed against the guide slope, and while the forming part 5 lifts the adjusting part 2 to move upward, the guide slope also pushes the forming part 5 in the direction of leaving the side wall of the movable groove 11, so that the direction in which the forming part 5 punches the product is gradually straightened to 90 degrees until the product is bent 90 degrees.
