Description

Technical Field

[0001] The present invention belongs to the technical field of metallurgy, and in particular relates to a feeding avoidance device and method for ultra-large, heavy-loaded, high-temperature arc-shaped feeding equipment. Background Art

[0002] Feeding devices are commonly used in the metallurgical industry for conveying materials. They are mostly used for feeding small, light-loaded products. They typically utilize a linear feed method, which uses rollers, belts, and other components, driven by a complex transmission system, to deliver the blank to the designated location. Some use a circular feed method, which often utilizes a grinding disc, feeding the entire forging synchronously with the pallet. Neither linear nor circular feed methods can overcome uneven bottom surfaces of the material.

[0003] Ultra-large, heavy-duty, high-temperature curved forgings are ultra-heavy, irregular, thin forgings with an outer diameter exceeding 10 meters, an inner diameter exceeding 6 meters, a maximum spread of 180°, and a blank thickness of approximately 0.3 meters. Symmetrical bosses are provided on the upper and lower surfaces. These forgings are made of specialized materials and operate in harsh environments, requiring superior mechanical properties and placing new and higher demands on the processing technology.

[0004] The processing technology for ultra-large, heavy-load, high-temperature curved forgings has been in the research and demonstration phase, initially exploring segmented forging and directional casting, and now focusing on the finalized one-piece forging technology. This one-piece forging requires dedicated ultra-large, heavy-load, high-temperature curved forging equipment. There is an urgent need to develop a feed avoidance device and method for ultra-large, heavy-load, high-temperature curved feeding equipment. Summary of the Invention

[0006] The present invention provides a feeding avoidance device for ultra-large heavy-load high-temperature arc feeding equipment, comprising a feeding avoidance component, an upper platform, a lower platform and a hydraulic cylinder; Both the upper and lower platforms are circular platforms, with the upper platform higher than the lower platform. The lower platform is fixed to the ground foundation, and the upper platform is fixed to the lower platform via hydraulic cylinders symmetrically distributed around the center. At the 12 o'clock and 6 o'clock positions, the upper and lower platforms are provided with arc-shaped notches running through them from top to bottom. The arc-shaped notch at 12 o'clock is equipped with a lower anvil fixed to the ground foundation. The upper surface of the upper platform is provided with centrally symmetrical through slots. According to the feeding direction, a front travel switch is provided in front of each through slot, and a rear travel switch is provided in the rear. A feeding avoidance assembly is installed in each through slot. The upper surface of the upper platform is also provided with a centering assembly staggered with the feeding avoidance assembly. On the bottom surface of each through groove, a group of two vertical guide slides are set near the outer edge and inner edge of the upper platform. In the middle of the two groups of guide slides, two pistons are arranged radially along the upper platform, and a proportional valve is connected between the two pistons; the slide of the feed avoidance component is U-shaped, and the horizontal section of the slide is fixed on the piston rods of the two pistons, and the vertical sections on the left and right sides of the slide are respectively mounted on the corresponding group of guide slides; a motor is fixed on the upper surface of the horizontal section of the slide, and the output end of the motor is connected to the transmission shaft through a reducer and a coupling.

The outer diameter of the tapered roller near the outer edge of the upper platform is larger than the outer diameter near the inner edge of the upper platform. The rotating shaft extends from the vertical section of the slide near the outer edge of the upper platform and is fixedly connected to the large gear; the large gear and the small gear are engaged; the ratio of the inner arc length to the outer arc length of the unfolded fan-shaped surface of the tapered roller is equal to the ratio of the inner circumference to the outer circumference of the upper platform; the intersection point of the extended line of the projection of the tapered roller on the upper surface of the upper platform coincides with the center of the circle of the upper surface of the upper platform; the top surface generatrix of the tapered roller is higher than the upper surface of the upper platform, and the top surface generatrix of all tapered rollers is located on the same horizontal plane; The hydraulic cylinder, the piston, the front stroke switch, the rear stroke switch and the proportional valve are respectively connected with the main machine of the super-large heavy-load high-temperature arc feeding equipment through cables.

[0007] Furthermore, the tapered roller is made of heat-resistant steel.

[0008] The feeding avoidance method for ultra-large heavy-load high-temperature arc feeding equipment of the present invention comprises the following steps: S10. Place the arc-shaped piece; Heat the semicircular arc-shaped piece to 1200°C and drag it from the side away from the lower anvil to the upper surface of the upper platform; S20.

Send the avoidance component to avoid; When the arc-shaped boss on the lower surface of the arc-shaped part runs to the rear stroke switch corresponding to a feed avoidance component, the rear stroke switch transmits the arrival signal to the main machine of the ultra-large heavy-load high-temperature arc forging equipment, the main machine shuts down the motor, the tapered roller stops rotating, and the main machine controls the two pistons of the feed avoidance component to descend synchronously through the proportional valve, driving the slide to descend horizontally under the limit of the two sets of guide slides, and at the same time driving the tapered roller to descend while the top surface generatrix remains horizontal, until the top surface generatrix of the tapered roller is lower than the upper surface of the upper platform; At the same time, the remaining tapered rollers of the feed avoidance assembly continue to rotate, pushing the arc-shaped part to continue to move in the clockwise direction toward the lower anvil until the boss of the arc-shaped part leaves the front travel switch. The front travel switch transmits the departure signal to the host of the ultra-large heavy-load high-temperature arc forging equipment. The host controls the two pistons of the feed avoidance assembly to rise synchronously through the proportional valve, driving the slide to rise horizontally under the limit of the two sets of guide slides, and at the same time driving the tapered roller to rise while the top surface busbar remains horizontal, until the tapered roller rises to its original position, the host starts the motor, and the tapered roller starts to rotate; By feeding the avoidance assembly and avoiding in sequence, the arc-shaped boss on the lower surface of the arc-shaped part passes through in sequence until the arc-shaped part is moved to the pre-set centering position; S40.
