Description

Technical Field

[0001] This invention relates to the field of metal hot forming die processing, and particularly to a die processing system for high-temperature alloy forging. Background Technology

[0002] High-temperature alloys are metallic materials based on iron, nickel, and cobalt that can work for a long time at high temperatures above 600°C and under certain stress. They have excellent high-temperature strength, good resistance to oxidation and hot corrosion, good fatigue performance, fracture toughness, and other comprehensive properties. They are also known as "superalloys" and are mainly used in the aerospace and energy fields.

[0003] For high-temperature die forging, high temperatures not only facilitate oxidation and gas permeation, but also enhance the mutual diffusion between the deformed metal and the die contact surface, making it easy for the billet to stick to the die, increasing the coefficient of friction and making it difficult to demold the forging. High-temperature alloy forging results in much more severe die wear than ordinary steel forging, which reduces the yield of forgings and greatly shortens the service life of the die.

[0004] In the high-temperature alloy forging process, friction loss and lubrication have become one of the key factors determining the success or failure of metal material forging. Currently, there are two main ways to reduce friction and enhance lubrication in the high-temperature alloy forging process: (1) When a temporary glass protective coating is applied to the surface of the billet before high-temperature alloy forging, the glass coating gradually softens and melts within the hot working temperature range, forming a dense protective molten 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, water-based or oil-based lubricant is uniformly sprayed into the mold cavity, which has the effects 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 also remain in the mold cavity during the previous forging, resulting in solid residue, which affects 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 leaves residue in some deep recesses of the mold cavity. When the blank comes into contact with the mold in the 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 when heated, causing the workpiece to jump and resulting in inaccurate workpiece positioning.

[0008] (3) The glass coating residue in the mold cavity is often manually polished with sandpaper and other workpieces, which makes production unsustainable and affects production capacity. It also poses a safety hazard at the press when manually handling the mold cavity.

[0009] (4) For the release agent spraying, manual spraying is used. Every time the forging press is pressed down, the manual person has to spray the release agent. The manual work intensity is high and the frequency is high. In addition, the release agent atomization is inhaled by the manual person, which has an impact on the manual person's health. Summary of the Invention

[0010] The purpose of this invention is to provide a mold processing system for high-temperature alloy forging. With the cooperation of a pressurizing device, a mold release agent station, and a grinding platform, a mechanical arm drives a mold release agent spraying device, an air blowing device, and a grinding device to automatically and quickly process the glass coating and residual mold release agent on the mold cavity, thereby improving the quality and production capacity of forgings, reducing the intensity of manual labor, and improving the safety of manual production.

Several mold release agent spray nozzles 232 are distributed on the front and opposite sides of the valve plate 231, their positions and numbers determined according to the shape and size of the mold, and are used to evenly spray the mold release agent into the mold cavity of the mold 10. Several short air nozzles 233 are distributed on the front and opposite sides of the valve plate 231, their positions and numbers determined according to the shape and size of the mold, and are used to blow away any residual mold release agent from the mold cavity of the mold 10. Several long air blowers 234 are distributed on the front and opposite sides of the valve plate 231. Their positions and numbers are determined according to the shape and size of the mold. They are used to blow away the release agent remaining in the recessed part 11 of the mold 10.

[0041] The grinding device 24 includes a grinding spindle 241, a floating tool holder 242, a quick-change tool holder 243, and a grinding head 244. The floating tool holder 242 is a hollow cylinder mounted on a bracket, which is fixedly connected to a valve plate 231. The grinding spindle 241, quick-change tool holder 243, and grinding head 244 are sequentially connected along an axis, forming a single unit that passes through the floating tool holder 242 and the valve plate 231. The grinding spindle 241 is energized, providing power to the grinding head 244 to rotate, thus cleaning the glass lubricant residue 12. The floating tool holder 242 allows for fine-tuning of the angle and position of the grinding head 244, enabling it to better adapt to changes in the mold cavity surface. The end of the quick-change tool holder 243 is connected to grinding heads 244 of different shapes.

[0042] Combination Figure 3The quick-change platform 40 is equipped with several quick-change brackets 41, which are connected and fixed to the quick-change platform 40 through mounting holes 42.

The necessary grinding heads and quick-change tool holders are pre-installed and placed on the quick-change bracket of the quick-change platform. When the press and mold are forging high-temperature alloy forgings, the guiding robot arm moves its gripper to the quick-change platform, automatically installing the required type of quick-change tool holder. After the high-temperature alloy forging is removed from the mold, the robot arm moves its gripper into the mold cavity. First, the grinding device grinds away any remaining glass coating in the mold cavity. Then, the air blower on the mold release agent spraying device blows away any remaining oxide scale and glass coating debris from the mold cavity. Next, the mold release agent spraying device evenly sprays mold release agent into the mold cavity. Finally, the long and short air blowers on the mold release agent spraying device blow away any remaining mold release agent from all parts of the mold cavity, especially the deep cavities. Then, the robot arm moves its gripper out of the mold cavity, allowing the press and mold to continue feeding the next blank for forging. If the grinding head wears out or the mold type is changed, the guide robot moves the gripper to the quick change platform, automatically removes the old grinding head's quick change handle and places it on the empty quick change bracket, and automatically installs the new type of quick change handle containing the grinding head.
