What titanium alloy forging manufacturers talk about is titanium alloy precision forging?

What are the technological characteristics?


  The use of precision forging machines to produce titanium and titanium alloy bars has the characteristics of high production efficiency, precise dimensions, good surface quality, and high material utilization. It has increasingly shown its superiority in the production of titanium bars. The technological characteristics of precision forging are as follows:

  (1) The hammer forging frequency is high, reaching hundreds or even thousands of times per minute. This loading method reduces the friction coefficient between the metal and the tool, the forging surface is smooth, and the internal deformation is uniform.

   (2) When hammer forging, each stroke stroke is small, the deformation is small, and the contact area with metal is small, which can greatly reduce the deformation force and deformation work, reduce the tonnage of the equipment and increase the service life of the tool.

  (3) The stroke of the hammer head can be adjusted arbitrarily, and the shape of the hammer head is adapted to the process size. There is no need to replace the hammer head. Forging rods with a certain size range can be produced.

  (4) During forging, the stroke of the four hammer heads remains unchanged, so the dimensional accuracy is high.

  (5) According to the temperature change of the blank during the deformation process, the feeding amount can be adjusted to realize isothermal forging.

  (6) According to the four hammers with arc-shaped grooves, the metal is compressed. The metal can only extend axially, so there will be no circumferential edges and cracks. This is different from the flat anvil compression during free forging.

  (7) High three-dimensional compressive stress will be generated during forging, which can increase the plasticity of the metal by 3 times and obtain a high pass forging ratio (pure titanium 6/1, alloy 4/1).

  (8) When the feed rate and pass reduction are large, a high thermal effect will be generated inside the blank, which will increase the deformation temperature. For example, the temperature rise of TC11 alloy can reach 90°C. Excessive temperature rise will coarsen the structure of the forging.
