Embodiment Construction

[0033] The present invention will be described below based on the illustrated embodiments. When explaining, the exhaust duct assembly A in the VGS type turbocharger using the turbine frame 2 of the present invention will be described, and the turbine frame 2 will be mentioned together, and then, the manufacturing method of the turbine frame will be described. .

[0034] Exhaust duct assembly A, especially when the engine is running at low speed to properly concentrate the exhaust gas G to regulate the exhaust flow, as an example such as figure 1 As shown in , there are a plurality of variable vanes 1 provided on the outer periphery of the exhaust turbine T and substantially setting the flow rate of exhaust gas, a turbine frame 2 that rotatably holds the variable vanes 1 , and makes the exhaust gas G to be appropriately set The variable blade 1 of the flow rate is formed by rotating the variable mechanism 3 at a certain angle. Each component will be described below.

Abstract

A novel method of manufacturing a turbine frame for rotatably holding adjustable blades in a VGS turbocharger is provided, which method is capable of manufacturing the turbine frame while almost eliminating a time-consuming cutting operation, whereby mass production of the turbine frame and the like can be realized. The invention is characterized in that: a blank which is punched out from a metalmaterial having a substantially constant thickness in such a manner as to integrally include a boss forming portion (24a) and a flange forming portion (23a) is used as a shaped material (W) serving asan original member for the turbine frame; when the shaped material (W) is processed, the boss forming portion (24a) is formed into a projecting state by a press forging tool; receiving holes for rotatably holding the respective adjustable blades are formed in the flange forming portion (23a) by punching; and when the shaped material (W) is processed, some or all of the manufacturing processes arecarried out in a warm condition.

Description

technical field [0001] The present invention relates to a novel manufacturing method that eliminates labor-intensive cutting work as much as possible when manufacturing a VGS type turbocharger used in an automobile engine, etc., especially when manufacturing a turbine frame incorporated therein to rotatably hold variable blades. Background technique [0002] As a supercharger used in a mechanism for increasing the power and performance of an automobile engine, the turbocharger is well known. This mechanism drives the turbine by the exhaust energy of the engine, and the output of the turbine makes the compression A device that rotates the engine to bring the engine to a supercharged state above that of natural aspiration. However, when the engine rotates at a low speed, the exhaust turbine hardly moves due to the low exhaust flow rate of this turbocharger. Therefore, when the engine rotates until the high-speed region, there is a sense of sluggishness until the turbine rotate...
