Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a flange stamping die that can be formed in one step. Background Technology

[0002] The most common methods for flange processing are forging and casting. Although casting is convenient and low-cost, flanges produced by casting have porosity, cracks, inclusions, and poor internal flowability. Forged flanges, on the other hand, have good flowability, denser structure, and better mechanical properties. However, forging is a complex process that requires multiple processing steps using different molds, resulting in low processing efficiency. Utility Model Content

On the top surface B of the first bending die 2312, the punch 131 includes a first pressing block 1311, a first bending die pressing block 1312, and a second pressing block 1313 arranged sequentially. The first pressing block 1311 and the first supporting die 2311 cooperate to form a first pressing groove 31. The first bending die pressing block 1312 and the first bending die 2312 cooperate to form a first bending groove 32 capable of bending the disc. The second pressing block 131... The first bending die 1312 and the second support mold 2313 are fitted together to form a second pressing groove 33 that can cooperate with the first pressing groove 31. The top surface C of the first bending die 1312 is lower than the top surface D of the second pressing block 1313, and the top surface C of the second pressing block 1313 is lower than the top surface B of the first bending die 2312, so that a second bending groove 34 is formed between the side of the second pressing block 1313 and the side of the second support mold 2313 and the first bending die 2312.

[0028] When a disc needs to be stamped, it is placed on the punch 131. The second stamping die 2 moves downward, and the die 231 on the second stamping die 2 gradually moves closer to the punch 131. The first pressing block 1311 and the first supporting die 2311 cooperate to press the inner circumference of the disc.
