Abstract

The invention discloses a hot-extrusion forming die for a saddle-type cross beam component and a forming method of the component. The hot-extrusion near-net forming method of the saddle-type cross beam component comprises the steps as follows: the size of a blank is determined preliminarily, and the blank is machined; the die and the blank are heated to the specified temperatures respectively, theblank is kept at the temperature for corresponding time, and hot-extrusion pre-forming of the saddle-type cross beam component is performed; a hot-extrusion pre-formed piece of the saddle-type crossbeam component is subjected to acid pickling, after acid pickling, surface folding defects and technological burrs are removed, and non-smooth transition positions are ground to be smooth; hot-extrusion near-net forming of the saddle-type cross beam component is performed, and a final formed piece is taken out. The saddle-type aluminum alloy cross beam component formed with the hot-extrusion near-net forming method is high in size precision and profile precision, the requirements can be met through finish machining of only a small quantity of assembly parts, the subsequent machining time can be greatly saved, and the production efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of hot forming, and relates to a forming mold and a component forming method. Background technique [0002] At present, aerospace product parts are developing in the direction of light weight, low cost and integration, and the application of saddle-shaped beam members is also increasing. This structure not only meets the high strength requirement but also realizes the light weight of the parts. At the same time, aluminum alloy materials are widely used in aerospace, rail transportation, weaponry and other fields due to their excellent performance. [0003] Due to the high strength requirements of such saddle-shaped beam members, it is difficult to meet the strength requirements by casting technology. In the past, thick plate machining was often used to manufacture, but the processing cost was high, the material utilization rate was low, and the processing efficiency was low. This type of component formed by isotherm...
