The forging method is used, but the shortest distance is secured through the shift-return method (one-step feed-return) to supply the material to be processed and to transfer it to each molding and processing step. The present invention relates to a manufacturing apparatus and a manufacturing method of a battery terminal plate which is pre-processed (primary processing) and finish processing (secondary processing) to meet specifications before processing the external shape of the processing material by punching.

As environmental regulations become stricter, the future competitiveness of the automotive market depends on the development of environmental vehicles. The interest in environmental vehicles, which began to heat up in the 1990s, was first developed and commercialized under the name of hybrid cars.

Moreover, due to the recent high oil prices and environmental issues, interest in eco-friendly vehicles has been amplified, and the hybrid electric vehicle (HEV) market has achieved high growth of more than 60% every year, and the market purchasing power of eco-friendly vehicles further increases. It is expected to do.

Hybrid cars are hybrid vehicles equipped with an internal combustion engine and electric motors, which means hybrid, which means that low-speed driving until a certain speed is reached after starting with an electric motor. The engine is operated and the electric motor is operated with auxiliary power to increase the acceleration. When the motor decelerates, the generator rotates with the force of the car and the kinetic energy of the vehicle is converted into electric energy and stored in the battery.

In addition, an electric vehicle (dedicated) that is driven by driving a motor with electric power charged in a battery has also been developed.

The battery mounted on the hybrid vehicle and the electric vehicle as described above is a battery that obtains and charges electricity through electrolysis generated at the positive electrode and the negative electrode. That is, a lithium ion secondary battery which is a device in which two electrodes of a positive electrode (copper) and a negative electrode (aluminum) are immersed apart from each other in a solution containing a cation and an anion.

In this case, the material in which deformation occurs may be an electrode (active material), a component of a solution, or may be dissolved into the solution. The current (ie electrons) enters the cathode, and the positively charged material in solution moves to this electrode and combines with the electrons to form a neutral element or molecule. The negatively charged components in the solution move to the anode, losing electrons and converting them into neutral elements or molecules. If the material to be changed is an electrode, a reaction usually occurs in which the electrode loses electrons and dissolves into solution.

Here, the positive electrode and the negative electrode are laser-welded to a terminal screwed to a cap plate that blocks the can (housing) opening of the battery and is received inside the can.
