Aluminum bending machine of Electric Car Battery Case

摘要

The present invention relates to an AL battery bending forming machine, and more specifically, in order to bend the aluminum sheet at a right angle, it is compressed by a press to form a compression groove in the aluminum sheet or to form a bending line in the electric vehicle AL It relates to a battery case bending molding machine. The present invention provides a bending machine for bending an aluminum plate of an electric vehicle AL battery case at a certain angle, the frame 10 supporting the press 20; When the press (20) is fastened and moved up and down, and the cylinder (31) in a cylindrical state is connected to the cylinder, and the press (20) descends, the aluminum plate (60) has compression grooves (35) at both ends. A punch 30 having a curved surface portion 33 to be formed, an end portion of the curved surface portion 33 and an extended guide shaft 32; Including the upper and lower guides (12, 14) for guiding the movement direction of the punch, characterized in that the compression grooves 35 are formed at both ends of the bent portion of the aluminum plate (60). The present invention is a method of vertically bending the battery case for an electric vehicle, so that a bending line and a compression groove can be formed in an aluminum plate by a press process, so that the bending portion of the aluminum plate is easily vertically bent, and the manufacturing time is longer than that of the prior art. It has the effect of being reduced to 1/10.
