Description

Technical Field

[0001] The invention relates to the field of metal hot forming die processing, and in particular to a die processing system for high-temperature alloy forging. Background Art

[0002] High-temperature alloy refers to a type of metal material based on iron, nickel and cobalt, which can work for a long time at high temperatures above 600°C and under certain stresses. It has excellent high-temperature strength, good oxidation resistance and thermal corrosion resistance, good fatigue performance, fracture toughness and other comprehensive properties. It is also called "superalloy" and is mainly used in the aerospace and energy fields.

[0003] For high-temperature die forging process, it is not only easy to oxidize and permeate at high temperature, but also the mutual diffusion between the deformed metal and the contact surface of the die is enhanced at high temperature, which makes the blank easily stick to the die, increases the friction coefficient and makes it difficult to demold the forging. The die wear of high-temperature alloy forging is much more serious than that of general steel forging, which reduces the yield of forgings and greatly reduces the service life of the die.

[0004] In the process of high-temperature alloy forging, friction loss and lubrication have become one of the key factors that determine the success or failure of metal material forging processing. Currently, there are two main ways to reduce friction and enhance lubrication in the process of high-temperature alloy forging: (1) Using a temporary glass protective coating on the surface of the billet before forging the high-temperature alloy, within the hot working temperature range, the glass coating gradually softens and melts to form a dense protective melt film between the protective substrate and the forging, blocking the direct contact between the two and avoiding oxidation and hydrogen absorption reactions. (2) Before forging, evenly spraying a water-based or oil-based lubricant in the mold cavity has the effect of cooling and forming a release agent lubricating coating.

[0005] The above method has the following problems:

[0006] (1) The glass protective coating will stick to the mold cavity during the forging process, and a small amount of oxide scale will remain in the mold cavity during the previous forging, causing solid residue, which will affect the formation of surface defects at the interface between the alloy material and the mold during the forging process;

[0007] (2) The surface lubricant sprayed on the mold forms residues in some deep recessed parts of the mold cavity. When the blank contacts the mold in a red-hot state, the residual lubricant will cause the surface of the blank in local contact to cool and harden, or the lubricant will vaporize due to heat, causing the workpiece to jump and cause inaccurate positioning of the workpiece;

[0008] (3) The glass coating residue in the mold cavity is attached to the mold cavity, and manual grinding with sandpaper and other workpieces is often used, which makes production unable to proceed continuously, affects production capacity, and also poses a safety hazard to the press when the mold cavity is manually handled;

[0009] (4) For the spraying of release agent, manual spraying is adopted. Every time the forging press is pressed down, the release agent must be sprayed manually. The manual work intensity is high and the frequency is high. In addition, the atomized release agent is inhaled by the human body, which has an impact on the human health. Summary of the invention
