Description

Technical Field

[0001] This invention relates to the field of special material heat treatment technology, specifically to a horizontal hard-pack end-face sleeve packaging device for cylindrical bars in the high-temperature alloy forging process, and more particularly to a horizontal bar hard-pack end-face sleeve packaging device. Background Technology

[0002] High-temperature alloys are metallic materials based on Fe, Ni, and Co that can resist oxidation and corrosion at temperatures above 600℃ and can operate for extended periods under certain stress. High-temperature alloys are key materials for hot-end components of aero-engines and various high-temperature components of rocket engines, as well as essential materials for high-temperature corrosion-resistant components required by energy, chemical, and other industrial sectors. Therefore, the quality and performance of high-temperature alloys are crucial for the development and safety of these fields.

[0003] In the production of high-temperature alloys, temperature control during the forging process is crucial to obtaining the desired microstructure and properties, such as fine-grained or ultrafine-grained microstructures, or to producing highly alloyed, difficult-to-deform high-temperature alloys. However, the temperature control window for critical forging processes is very small, meaning the forging temperature range is limited, and the billet transfer time after exiting the furnace typically needs to be accurate to the second. Therefore, temperature control is one of the key process parameters during hot working.

[0004] In actual production, to control the forging temperature, the heating temperature of forgings is usually set at the upper limit of the deformable temperature range, and methods such as sheathing are used to slow down heat loss during the transfer and hot working processes. The higher the insulation efficiency of the insulation material and the shorter the transfer and deformation time of the billet, the better the deformed microstructure properties. Sheathing refers to covering the surface of the steel billet with insulation materials such as aluminum silicate fiber blankets to slow down heat loss caused by thermal radiation and convection, and to prevent heat transfer between the mold and the billet, as well as to block heat transfer between the billet and the air. Methods for fixing the insulation material to the surface of the billet are divided into hard sheathing and soft sheathing. Hard sheathing is fixed by welding a stainless steel outer sleeve, while soft sheathing is fixed by adhesive bonding.

[0005] Currently, the main method is to directly wrap the blanks manually. This method has problems such as high labor intensity, harsh working environment, and large fluctuations in wrapping time and wrapping quality. An automated hard-sleeve packaging device is needed to improve production efficiency and ensure product quality.

[0006] Patent 201922422514.7, "A Heat Insulation Device for Steel Ingots or Billets in High-Temperature Alloy Forging Process," employs multiple symmetrically arranged robotic arms. Each robotic arm consists of several joints, and each joint is individually driven by a pneumatic or hydraulic cylinder. The robotic arms wrap self-adhesive heat insulation blankets around the surface of the bar stock. However, it does not involve the insulation layer packaging on the end face of the bar stock.

[0007] This invention proposes a horizontal hard-end sleeve packaging device for high-temperature alloy bars. This device can achieve automated end sleeve packaging, reduce labor intensity, and improve packaging efficiency and product quality. Part of the packaging structure uses springs for automatic return, reducing the number of drives and control complexity. Summary of the Invention

The packaged steel plate has the shape shown in the image. Figure 9 As shown in b.
