Description

Technical Field

[0001] This utility model relates to the field of forging die technology, specifically to a steering knuckle forging die that is easy to connect and fix. Background Technology

[0002] The steering knuckle is a key component of the automotive steering system, and its quality and performance directly affect the vehicle's driving safety and handling. Forging is an important method for steering knuckle production, and forging dies are the core equipment to ensure the forging quality of steering knuckles. In the entire steering knuckle production process, the pre-fabrication of the blank before forging (usually using a casting process) is a key preliminary step.

[0003] The forging die for an automotive steering knuckle disclosed in publication number "CN206028630U" includes an upper die and a lower die. The upper die surface has an upper die cavity in the middle, and the lower die surface has a lower die cavity in the middle. The upper die cavity and the lower die cavity cooperate to form a steering knuckle cavity. The upper die surface and the lower die surface are respectively provided with corresponding positioning protrusions and positioning grooves. The positioning protrusions and positioning grooves cooperate to complete the precise fit between the upper and lower dies. The top of the upper die punch is provided with a rounded corner, and the root of the lower die die is provided with a rounded corner. By setting reasonable rounded corners, the forging has good fluidity, easy filling, ensures the quality of the forging, and improves work efficiency.

[0004] However, the above-mentioned device still has the following problems during implementation: 1. The existing steering knuckle forging die casting operation mostly uses a single template, and the number of templates set at the same time is small. Only 1-2 blanks can be cast at a time, which cannot match the high-efficiency production rhythm of the forging die, forming a capacity bottleneck and resulting in low production efficiency of the forging die. 2. Most existing steering knuckle forging dies have fixed templates. When different specifications of steering knuckle blanks need to be produced, the template frame needs to be completely disassembled and the positioning and fixing structure adjusted. This is time-consuming, labor-intensive, and cumbersome, increasing the difficulty of the workers' work. Utility Model Content
