Benefits of technology

[0010]According to the present invention, the manufacturing thereof in a progressive press system becomes possible, productivity thereof can be enhanced, and the cost reduction thereof can be achieved.

Problems solved by technology

However, when the drawing depth is about 20 mm or more, the drawing becomes “deep drawing”; thus, the working by the progressive press system becomes difficult, and a single press system or scheme has to be employed.
However, the production efficiency of the single press system is low, resulting in increasing the production cost.
However, since the publicly known technology is related to the single press system, the above-mentioned advantage in the progressive press system cannot be obtained.

first embodiment

[0021]In advance of explaining the method of producing a heat shield, an explanation will be given by reference to FIG. 1 of the schematic structure of a vehicle-mounted actuator including a motor unit that is the object to be shielded from heat from an engine using the heat shield according to the embodiment. A vehicle-mounted actuator 1 is basically composed of an actuator unit 2 and a motor unit 3 for driving the actuator unit 2, and further, the motor unit 3 consists of a motor main body 4 and a circuit main body 5 for driving the motor.

[0022]The circuit main body 5 has an external input-and-output connector 6, a terminal 7, a board 18 connected with the terminal 7, and other components. The motor main body 4 includes a stator 8 polarized into a plurality of poles, a coil 9 wound on the stator 8, a rotor 10, a magnet 11 rotating integrally with the rotor 10, bearings 12, 13 supporting the rotor 10, a base 25, a cylindrical supporting unit 26 slidably supporting an output shaft 1...

Abstract

A method of producing a heat shield includes the step of producing a plate-shaped material provided by developing a funnel shape having a plurality of face sections (20, 21, 22) which are adjacent to each other and one (20) of which is a mounting surface and the bending step of bending the plate-shaped material such that the face sections (21, 22) other than the face section (20) corresponding to the mounting surface are orthogonal to the mounting surface section.

Description

TECHNICAL FIELD[0001]The present invention relates to a method of producing a heat shield that three-dimensionally surrounds an object to be shielded from heat.BACKGROUND ART[0002]In the opening-adjusting system of a turbocharger vane and an EGR system which are accessorily provided on an engine of an automobile or the like, a motor is used for a vehicle-mounted actuator for driving the above systems. The vehicle-mounted actuator is disposed in an environment to which heat from the engine is conducted. For this reason, in order to protect particularly a motor unit having a motor main body, a circuit main body therefor, and so on from the heat of the engine, a structure in which the motor unit is covered with a heat shield has been adopted.[0003]The motor unit as an object to be shielded from heat has a three-dimensional shape such as a cylinder, and the heat shield is arranged to have, at its corner area, a funnel shape composed of a plurality of face sections adjacent to each other...
