Introduction to Forging Presses for New Energy Battery Terminals

The forging press for new energy battery terminals, manufactured by Dongguan Jianlong Hydraulic Technology in China, is specialized equipment designed for the precision forging of battery terminals (positive terminals, negative terminals, and battery connectors) used in products such as power batteries for new energy vehicles and energy storage batteries. Its primary function is to induce plastic deformation in metal materials through applied pressure, resulting in terminal products characterized by high strength, high electrical conductivity, and high dimensional accuracy. The following information is provided by the team at Jianlong Hydraulic Technology to assist you in your procurement process.

1. Core Components and Functions of the Forging Press

A complete forging press for battery terminals typically consists of the following core components working in unison:

1.1 Main Forging Unit: Provides the core pressure required for forming. The equipment covers a wide tonnage range—from 110 to 500 tons—with models reaching up to 3,000 tons available for specialized components (such as IGBT heat sinks).

1.2 Precision Die System: A critical component determining the final shape and dimensional accuracy of the terminal. By using die cavities to constrain metal flow, the system can form complex structures where the terminal body and the connecting tab are integrated into a single piece.

1.3 Automatic Feeding Device: Designed to facilitate continuous, high-efficiency production. For example, a rotary feeding tray combined with magnetic clamping and positioning enables automatic raw material loading, precise positioning, and finished product discharge, significantly boosting overall efficiency.

2. Core Processes and Technological Innovations

Forging technology for battery terminals continues to evolve, characterized primarily by:

2.1 Integrated Forming Process: Uses forging to form the terminal and connecting tab as a single, integrated unit. Compared to traditional machining methods, this approach significantly improves material utilization and reduces costs.

2.2 High-Precision Positioning and Clamping: To ensure forging accuracy, the equipment employs specialized fixing and clamping mechanisms. For instance, linkage assemblies enable the simultaneous clamping of raw materials and the die body, ensuring concentricity and uniform force distribution. Additionally, designs utilizing magnetic components allow for the automatic clamping and release of raw materials during the forging process without interfering with the operation. 2.3 Automation and Continuous Production: A continuous forging/pressing feeding system is key to enhancing efficiency. By automating the processes of loading, positioning, clamping, and unloading, it minimizes manual intervention and ensures the reliability of large-scale production.
