Manufacturing device of bus bar and manufacturing method thereof

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...

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
