Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to an extrusion device for processing a battery shell. Background Art

[0002] A battery refers to a cup, trough or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate an electric current. It is a device that can convert chemical energy into electrical energy. It has a positive electrode and a negative electrode. With the advancement of science and technology, batteries generally refer to small devices that can generate electrical energy, such as solar cells. The performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. Using batteries as an energy source can obtain stable voltage, stable current, and long-term stable power supply. Battery shell aluminum profile extrusion refers to the extrusion of the shell to obtain a battery shell of corresponding size during battery processing.

[0003] The existing patent number is CN 212734104 U. A battery shell aluminum profile extrusion device, the battery shell formed inside the forming frame 10 moves downward to the front end of the fan 18. The setting of the fan 18 accelerates the cooling of the battery shell, shortens the cooling time, and increases work efficiency.

[0008] By adopting the above technical scheme, when in use, the metal solution is added to the extrusion groove on the battery extrusion box on the forming frame through the metal solution adding device, and the hydraulic telescopic rod is contracted at this time to drive the battery extrusion box to move to the bottom of the extrusion die. The extrusion frame slides under the drive of the telescopic motor until the extrusion die is aligned with the extrusion groove, and the hydraulic telescopic rod is extended to drive the battery extrusion box to approach the extrusion die, and the extrusion die extrude the metal solution in the extrusion groove to form. After the battery shell is formed, the hydraulic telescopic rod is contracted to make the battery extrusion box probe into the temperature regulating pool for cooling. The temperature regulating pool setting can wrap the battery extrusion box and evenly cool it, which can effectively improve the cooling rate and cooling effect of the battery shell. The temperature regulating pool can control the water temperature according to actual needs by adjusting the filling amount of cold water and hot water and cooperating with the temperature sensor to avoid cracking and damage caused by rapid cooling of the battery shell. It can not only improve the cooling effect but also increase the water temperature to heat the battery shell to eliminate the residual stress inside the battery shell, which can effectively improve the product quality of the battery shell.

[0009] Furthermore, the metal solution adding device includes a mounting plate, which is fixedly arranged on the top wall of the support frame, and a plurality of pipes are arranged through the mounting plate. A liquid adding funnel is arranged at the top end of the pipe, and a liquid adding nozzle is arranged at the bottom end of the pipe, and the liquid adding nozzle is arranged to align with the battery extrusion box.

[0010] By adopting the above technical solution, the metal solution is poured into the liquid adding funnel during use, and the metal solution flows from the pipeline into the liquid adding nozzle. Since the liquid adding nozzle is aligned with the battery extrusion box, the metal solution can be safely added into the extrusion groove for subsequent processing.

[0011] Furthermore, a heat-insulating shell that wraps the pipeline is fixedly provided on the outer wall of the mounting plate, and the heat-insulating shell is a heat-insulating material filled with a sufficient amount of foam asbestos.

Combined with the heat dissipation fan, the air flow rate near the heat dissipation fins is increased, so the liquid circulating between the cold water pool and the temperature control pool can be well cooled, ensuring that a steady stream of cold water can wrap around the battery extrusion box for cooling. The heater can heat the liquid in the hot water pool, ensuring that a steady stream of hot water can participate in controlling the temperature of the temperature control pool. Combined with the temperature sensor, the temperature control pool can be stably controlled to reach a suitable working temperature.

[0017] Furthermore, the outer wall of the battery extrusion box is fixedly provided with a plurality of heat exchange ridges which are spaced apart and arranged in parallel with each other.

[0018] By adopting the above technical solution, the setting of the heat exchange ridges can effectively increase the contact area between the battery extrusion box and the liquid in the temperature regulating pool, effectively increase the heat exchange rate between the two, increase the speed of cooling or heating, and greatly improve production efficiency.

[0019] Furthermore, the hydraulic telescopic rod is externally connected to an oil system, and the oil system, telescopic motor, liquid pump, temperature sensor, drive motor and heater are externally connected to a control system, thereby achieving an effect of organically controlling each component to operate in close automated coordination.

[0020] In summary, the beneficial technical effects of the utility model are:

[0021] 1. An external cold water pool and hot water pool temperature regulating pool are used to evenly cool the battery extrusion box in a wrapped manner, which can effectively improve the cooling rate and cooling effect of the battery shell;
