The heat transfer coefficient between the block die forging slab and boiling water has an effect on the cooling deformation

Many industries will need a variety of parts to assemble and manufacture related products, such as essential parts. Different kinds of parts have different functions. In order to better meet the needs of all walks of life, more types of forging of these parts are produced. For example, for products like block die forging, what is the block die forging like when forging? Now we have the technology to observe how the forging process of the block die forging is, which can better ensure the quality of production.

In block forging manufacturing industry, put forward the process of large aluminum alloy air local deformation of slab, using 3 d finite element software forging deformation uniformity of strain distribution between two parts, according to the result of practice can be seen that the large isothermal forging part loading process can effectively reduce the ground load, by 2 times part of the load is more suitable for production of large aviation die forgings, In each step forming process, the temperature field of the die forging is uniform.

By understanding advanced forging equipment and key forging technology, in the development of aviation industry, the important role of the finite element method, through understanding of boiling water cooling and aluminum alloy forging aging treatment, to study the heat transfer coefficient between slab and boiling water for cooling in the process of deformation, the influence of change and the rest of the die forgings materials about the water, The effect of process parameters and heat treatment of die forged aluminum alloy.

Studies in the literature, as a control and improving the forging heat treatment process has a certain significance, in order to adapt to the development of the aviation industry, is developing large-scale forging aviation parts, as represented by the forging press advanced equipment debugging, create large die forgings in domestic capacity will gradually increase, when the seal no negative clearance in the process of die forgings punch mould, You can reduce the additional process of removing burrs during stamping and cutting.

Currently considering no unified fixed mode for die forgings raw material specifications, influence of the specifications of the raw materials for die forgings and several principles of factors, put forward to determine the specifications are discussed in the forging process control, improved the forging of the specifications of the raw materials, effectiveness and punctuality, reliability theory and practice show that Reasonable use of these principles can effectively improve the forging process matrix, reduce the consumption of raw materials to improve the quality of the die forging, enhance the service life of the die forging, and reduce the cost of the die forging.
