Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to an automatic feeding device for a seamless steel pipe raw material heating furnace. Background Art

[0002] Seamless steel pipe is made by perforating a whole round steel bar. There is no weld on the surface of the seamless steel pipe. According to the production method, seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, extruded seamless steel pipe, jacking pipe, etc. When producing hot-rolled seamless steel pipe, the main production processes are: tube blank preparation and inspection, tube blank heating, perforation, tube rolling, steel pipe reheating, sizing, heat treatment, finished tube straightening, finishing, inspection and other steps. When heating the tube blank, it is necessary to place the tube blank in the raw material heating furnace for heating. The existing raw material heating furnace usually adopts a step-by-step heating method for heating, that is, the raw material is placed in the raw material heating furnace, and the stepping mechanism in the heating furnace drives the raw material to move in the raw material heating furnace to heat the raw material in sections.

[0003] At present, the movable block on the existing screw realizes back and forth movement under the limitation of the limit rod during the rotation process. The movable block adjusts the movable plate on the rotating seat to a certain angle through the hinge and the hinge rod during the back and forth movement between the screw and the limit rod, so that the raw materials on the conveyor belt enter the entrance of the heating furnace, are automatically put in, and are adjusted to different heights to meet various needs, with high practical value.

[0004] For example, a raw material conveying device for a seamless steel pipe raw material heating furnace disclosed in the authorization number CN219913981U includes a base plate, a base box, a movable block, a movable plate and a side plate, the base box is fixedly installed at the top center of the base plate by bolts, a motor is fixedly installed at the center of one end of the inner side of the base box by bolts, a screw is fixedly installed at the output end of the motor, the screw is threadedly connected with the movable block in the base box, a rotating seat is fixedly installed at the top end of the outer side of the base box by bolts, the movable plate is movably connected between the rotating seats by a rotating shaft, hinges are fixedly installed at both sides of one side of the bottom of the movable plate and at both ends of the top of the movable block by bolts, a hinge rod is movably connected between the movable plate and the movable block by the hinge, the side plates are installed at both sides of the top of the movable plate by bolt fixing rods, a conveyor belt is fixedly installed between the middle parts of the two ends of the side plate by bolts, and a plurality of push plates are evenly installed on one side of the top of the conveyor belt by bolts. However, the raw material conveying device of such a seamless steel pipe raw material heating furnace is not convenient for moving the loading device, and part of the raw materials are easy to fall to the outside of the heating furnace.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that it is inconvenient to move the loading device, and part of the raw materials are easy to fall to the outside of the heating furnace. Therefore, it is necessary to improve the existing technology. Utility Model Content
