What is titanium alloy precision forging discussed by titanium alloy forging manufacturers? What are the process characteristics?

The production of titanium and titanium alloy rods using precision forging machines has the characteristics of high production efficiency, precise dimensions, good surface quality, and high material utilization rate. Its superiority is increasingly demonstrated in the production of titanium rods. The process characteristics of precision forging are as follows:

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

(2) When forging the hammer head, the stroke is small, the deformation is small, and the contact area with the metal is small, which can greatly reduce the deformation force and deformation work, reduce the tonnage of the equipment, and improve 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 more adaptable to the process size, so there is no need to replace the hammer head. It can produce forging rods with a certain size range.

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

(5) The feeding amount can be adjusted according to the temperature changes of the billet during the deformation process to achieve isothermal forging.

(6) According to the four hammer heads with arc-shaped grooves, the metal can only extend axially, so it will not produce circumferential edges and cracks, which is different from the flat anvil compression during free forging.

(7) During forging, high triaxial compressive stress will be generated, which can increase the plasticity of the metal by three times and achieve a high pass forging ratio (pure titanium 6/1, alloy 4/1).

(8) When the feeding speed and pass pressure are large, a high thermal effect will be generated inside the billet, causing an increase in deformation temperature. The temperature rise of TC11 alloy can reach 90 ℃. Excessive temperature rise will cause coarsening of the forging structure.
