Problems solved by technology

[0003] The purpose of the present invention is to provide a heavy-duty high-efficiency cutting turn-milling compound broken-line blade to solve the problem of easy fracture and failure when the single-edged welded turning tool is subjected to strong mechanical impact in the rough machining of super-large cylindrical forgings. During the cutting process, the high temperature causes the blade to lose the hardness required for cutting and is reversely cut by the workpiece

Abstract

The invention relates to a heavy type high-efficient composite broken line edge blade for cutting and turn milling, belongs to the technical field of tools for turn milling machining, and solves the problems that a single blade welded type lathe tool is easy to fracture and becomes invalid when bearing a heavy mechanical shock in the rough machining process of an ultra-large barrel forged piece blank, and a blade is cut by a workpiece due to the loss of the hardness required by cutting at the high temperature in the cutting process. Flank surfaces of the cutting tool are formed by alternately connecting long inclined planes with short inclined planes in sequence; long cutting edges and short cutting edges are combined to form the broken line-shaped cutting edges; long edges and short edges are formed at the periphery of the external surface of a raised platform; the long cutting edges are provided with long inclined planes which incline to the bottom of the raised platform; inverted trapezoid chip breaker grooves are formed in the areas between the long inclined planes and sides of the long edges; the short cutting edges are provided with short inclined planes which incline to the bottom of the raised platform; V-shaped chip breaker grooves are formed in the areas between the short inclined planes and the sides of the short edges of the raised platform; and a bottom surface of the blade is provided with bottom heat radiating grooves. The heavy type high-efficient composite broken line edge blade for cutting and turn milling is used for cutting, turning and milling the large hydrogenation barrel blank.

Description

technical field [0001] The invention belongs to the technical field of cutting tools for turning and milling, and in particular relates to a heavy-duty high-efficiency cutting turning and milling compound broken line blade. Background technique [0002] The large-scale hydrogenation cylinder blank is directly forged, and the weight can reach more than 400 tons. There are many forging defects on the surface to be processed that ordinary forgings do not have, such as: forging shovel grooves, oxide scales, forging cracks and metal coverings, etc.; The materials used in the hydrogen cylinder section are quite special and have strong high temperature toughness. At present, turning and milling are required for the processing of hydrogenation cylinders. For example, the cutting tool used in turning processing is a single-edged welded turning tool. The cutting amount caused by forging defects during the processing changes greatly, and the mechanical impact on the cutting tool is alw...
