AI Technical Summary
The existing short shaft forging process is long and has low material utilization, making it impossible to form efficiently.
Design a short-shaft closed forging forming die for a 400T closed single-point press, including an upper die and a lower die. The lower die has multiple grooves with gradually decreasing diameters. Combined with the ejector pin, it realizes the direct forming and removal of the forging, eliminating the edge trimming process.
By directly molding and eliminating the trimming process, material utilization is improved and labor costs are reduced.

Abstract
Claims
1. A short shaft closed forging forming die for 400T closed single point press, comprising an upper die (1), characterized in that: The lower end of the upper mold (1) is provided with a lower mold (2). The lower mold (2) is provided with groove one (21), groove two (22) and groove three (23) from top to bottom. The lower mold (2) is used to place the forging (4).
2. A short-shaft closed forging forming die for a 400T closed single-point press according to claim 1, characterized in that: The cross-sections of the first groove (21), the second groove (22), and the third groove (23) are all circular, and their diameters are set from largest to smallest.
3. A short axis closed die for use in a 400T closed-die single point press according to claim 2, wherein: The inner wall of the first groove (21) matches the outer wall of the lower end of the upper mold (1), the second groove (22) matches the initial width of the forging (4), and the third groove (23) matches the top rod (3).
4. A short axis closed die for use in a 400T closed-die single point press according to claim 3, wherein: After the forging (4) is placed in the second groove (22), the ratio of the distance between the top surface of the forging (4) and the top surface of the second groove (22) to the diameter of the second groove (22) should be less than 2.5.
