Description

Technical Field

[0001] The utility model relates to the technical field of steel rod grinding devices, in particular to a novel wear-resistant steel rod grinding device. Background Art

[0002] The surface of the wear-resistant steel rod has been heat-treated and has good wear resistance and thermal stability. It is mainly used in rod mills. The surface of the wear-resistant steel rod needs to be polished after leaving the factory and after long-term use.

[0003] The existing grinding device uses centerless grinding to grind the wear-resistant steel rod, but centerless grinding mainly relies on the deadweight of the metal rod for grinding. The surface of the wear-resistant steel rod has good wear resistance and strength, resulting in low grinding efficiency. The existing technology also uses manual grinding, placing the wear-resistant steel rod on one side of the grinding wheel for grinding, which is time-consuming, labor-intensive, and has low grinding efficiency, and is prone to uneven grinding.

[0006] A novel wear-resistant steel rod grinding device comprises a structural frame, wherein a plurality of grinding mechanisms are arranged inside the structural frame, wherein the grinding mechanisms are symmetrically arranged on both sides of the wear-resistant steel rod along the axis of the wear-resistant steel rod, and the wear-resistant steel rod passes through the gap between the grinding mechanisms located on both sides; the grinding mechanism comprises a mounting frame, wherein two grinding wheels are arranged at intervals inside the mounting frame, and one end of the grinding wheel is externally connected to a motor, and the contact surface between the grinding wheel and the wear-resistant steel rod is inclined, and the mounting frame is connected to the output end of an electric telescopic cylinder on the side away from the grinding wheel, and the tail end of the electric telescopic cylinder is fixed on the structural frame.

[0007] Preferably, the grinding wheel is recessed from both ends toward the middle and matches the outer shape of the wear-resistant steel rod, so that the wear-resistant steel rod is in more complete contact with the grinding wheel.

[0008] Preferably, the surface grain sizes of the multiple grinding wheels of the multiple grinding mechanisms decrease successively from front to back along the feeding direction of the wear-resistant steel rod.

[0009] Preferably, a circulating water tank is installed on one side of the structural frame, and the circulating water tank outputs cooling water through pipelines and nozzles and sprays the cooling water to the contact position between the wear-resistant steel rod and the grinding mechanism.

[0010] Preferably, water baffles are provided on both sides of the grinding mechanism located below or obliquely below the wear-resistant steel rod, and the edges of the water baffles are inclined to collect cooling water output by the nozzle.

[0011] To sum up, the utility model has the following beneficial technical effects: the utility model sets up multiple groups of grinding mechanisms, each group of grinding mechanisms includes two grinding wheels arranged at intervals, which are used to grind wear-resistant steel rods. The wear-resistant steel rods are in contact with the grinding wheels and rotate and feed along the inclination direction of the grinding wheels. The surface of the wear-resistant steel rods can be grinded without dead angles, effectively ensuring that the contact surface between the wear-resistant steel rods and the grinding wheels is uniform and sufficient; the wear-resistant steel rods to be grinded enter and pass through the gap between the grinding mechanisms on both sides, and the particle size of the grinding wheel surface decreases successively, thereby realizing one-time grinding and forming of the wear-resistant steel rods and improving processing efficiency.
