Embodiment Construction

[0016] The embodiment of the present invention provides a method for finishing the three-dimensional impeller made of FV520B with a solid carbide tool, including the following steps:

[0017] After the rough machining of the three-dimensional impeller blank by milling the shaft disk, it is required to reserve a machining allowance of 0.7-1mm on one side of the blade.

[0018] Cleaning of the rounded corner of the blade, finishing of the round head of the leading edge of the blade, and finishing of the impeller hub. Among them, the clearance value between the tool ball head and the hub during blade fillet cleaning process is set to 0.5mm.

[0019] The blade is semi-finished with a long-blade tapered ball-end integral carbide wave-edge milling cutter, and a finishing allowance of 0.2-0.5mm is reserved on one side of the blade. Among them, the gap between the tool ball and the hub during the semi-finishing process of the blade is set to 0.7 mm, and the gap between the tool ball ...

Abstract

The invention provides a method for finish machining of a three-dimensional impeller made of an FV520B material through integral hard alloy cutters. The method comprises the steps that after rough machining is carried out on a three-dimensional impeller blank milled by a shaft disc, it is required that the machining allowance of 0.7-1 mm is reserved on the single side of each blade; root cleaningis carried out on rounded corners of the blades, front round heads of the blades are subjected to finish machining, and a hub of the impeller is subjected to finish machining; semi-finish machining iscarried out on the blades by using the long-bladed taper ball integral hard alloy corrugated milling cutter, and the finish machining allowance of 0.2-0.5 mm is reserved on the single side of each blade; and finish machining is carried out on the blades by using the long-bladed taper ball integral hard alloy milling cutter, and the thickness of the blades is machined to a designed sizes. The method for finish machining of the three-dimensional impeller made of the FV520B material through the integral hard alloy cutters is high in machining efficiency and good in economic benefit.

Description

technical field [0001] The invention relates to the technical field of ternary impeller processing, in particular to a method for finishing a ternary impeller made of FV520B with an integral carbide tool. Background technique [0002] At present, in the method of milling the three-dimensional impeller of the shaft disk, the tapered long-edged high-speed steel cutter is used to process the blades. The feed speed of the cutter is slow. The feed rate of the semi-finishing blades is generally 50-80mm / min. The feed rate of the blade is generally 100-150mm / min. The method has slow processing speed, low processing efficiency and long product processing and manufacturing cycle, resulting in high production cost and low economic benefit. Therefore, there is an urgent need for a method for finishing the ternary impeller made of FV520B material with high processing efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provi...
