Problems solved by technology

However, since the wire rod is subjected to bending processing and then extruded into a plate shape, an operation for this extrusion and a metal mold for this operation are also required, and thus there is a problem that the obtained weight cannot be sufficiently reduced. Unresolved issues such as the unit price of bus bars

Embodiment Construction

[0029] Next, the best mode for carrying out the present invention will be described with reference to the drawings.

[0030] figure 1 as well as figure 2 The manufacturing apparatus 20 of the bus bar of this invention is shown. Such as Figure 9 As shown, the manufacturing device 20 automatically manufactures the elongated and elongated main body portion 12a, and the main body portion 12a extending from the predetermined position of the main body portion 12a to the main body by bending the metal elongated square wire 14. The bus bar 12 is the fins 12b, 12c protruding in a folded or cantilever shape in the direction where the portion 12a intersects.

[0031] For the square wire 14, a relatively thick wire material that can maintain its shape when bent is used. In this embodiment, a case is shown in which a so-called square wire 14 is used, and the cross section of the square wire 14 on which an insulating film is formed on the surface is formed in a rectangular shape. If ...

Abstract

The present invention provides a manufacturing device of a bus bar and a manufacturing method thereof. No metal mold is used for manufacturing. The manufacturing process can be simplified and a plurality of kinds of bus bars can be manufactured more easily. The manufacturing device of the bus bar is provided with the following components: a conveying device which guides square lines out in a long-edge direction; a first holding device which holds the guided-out square lines; a first holding movement actuator which causes the first holding device to move along a long-edge direction of the square line; a second holding device which holds the square lines which is closer to the downstream side than the first holding device; a second holding movement actuator which causes the second holding device to move along the long edge direction of the square line; and a machining actuator which causes a contact component that contacts with the square lines between the first holding device and the second holding device to reciprocate in a direction that is orthogonal with the square lines for causing projection of the square lines to side part. The manufacturing method comprises the following steps: a guiding-out step for forming a plate-shaped body part composed of square lines through guiding-out the square lines, and a fin forming process for forming the fin which is projected from the side margin of the body part, wherein the two steps are carried out repeatedly.

Description

technical field [0001] The present invention relates to a bus bar manufacturing device and method for manufacturing bus bars used in centralized power distribution parts of brushless motors. Background technique [0002] In recent years, there has been a large demand for lower fuel consumption of vehicles, and as one example, the development of ultra-high fuel-efficient hybrid vehicles is progressing. In particular, recently, a hybrid vehicle including an auxiliary power mechanism (motor auxiliary mechanism) that uses an engine as the main power and uses a DC brushless motor to assist the engine during acceleration or the like has been proposed. However, since the brushless motor constituting the motor auxiliary mechanism is arranged in a limited space in the engine room, specifically, in a narrow space between the engine and the transmission, there are great restrictions on installation. Therefore, such a brushless motor is required to be thin. [0003] Among them, a thin...
