specific Embodiment approach 1

[0035] Specific implementation mode one: combine Figure 1~4 Describe this embodiment, this embodiment includes torsion mechanism 1, punch 2, anti-skid structure 2-1, sleeve 3, thread 3-1, blank 4, circular plate 4-1, local restraint ring 5, bolt 6. Flange 7, base 8, annular limit block 9. This embodiment is completed by the following steps: 1. According to the requirements of the shape and size of the prepared plate and the degree of grain refinement, select annular limiters 9 or split limiters 10 with different heights h and different inner diameters d, different Sleeve 3 with rounded corner R will get the corresponding deformation ratio; 2. Put the bolt 6 into the counterbore of the base 8, and put the base 8 and the bolt 6 together on the press table; 3. Put the selected The bolt holes on the ring-shaped limit block 9 or the split limit block 10 are aligned with the bolts 6 on the base 8, and the local restraint ring 5 is placed at the center of the base 8; 4. Place the s...

Abstract

The invention discloses a short process extrusion forming device and method for a high-performance metal plate and relates to an efficient extrusion forming device and method for a metal plate. The series of problems that energy consumption needed by an existing metal plate extrusion forming method is large, the number of procedures is large, the material utilization rate is low, the technologicalflexibility is poor, and quality performance coordination control is difficult can be solved. According to the efficient extrusion forming device, an antiskid structure 2-1 is designed at the end ofa male die 2; a sleeve 3 and a flange 7 are connected with each other through a thread 3-1; and the shape and thickness of the extrusion plate are adjusted and controlled through an annular limiting block 9 or a split limiting block 10 and adjustment of the height h. According to the efficient extrusion forming method, after a blank 4 is put into the sleeve 3, a torsion mechanism 1 drives the maledie 2 to go downwards for loading, and the blank 4 sequentially flows into a bottom cavity till complete extrusion is achieved. According to the efficient extrusion forming method, a fine grain modification effect of strong plastic deformation technology can be achieved without additional procedures, and plate products of different specifications can be customized. The efficient extrusion formingdevice and method are suitable for extrusion forming of high-performance metal plate products.

Description

technical field [0001] The invention relates to a processing and forming method for metal plates, in particular to a short-flow extrusion forming method for high-performance metal plates, and belongs to the technical field of extrusion forming. Background technique [0002] Due to the structural characteristics of light weight and thin walls, sheet metal components can realize the long-term pursuit of energy saving and emission reduction in the fields of aerospace, transportation, weaponry and civilian product manufacturing through lightweight design. Therefore, the amount of high-performance metal sheets is increasing year by year. Incremental and widening scope of use, favored by researchers. At present, the existing high-performance sheet metal processing and forming methods mainly include rolling, casting and extrusion. [0003] The traditional rolling process of plate is divided into: hot rolling, warm rolling, cold rolling and so on. Among them, due to the high tempe...
