Problems solved by technology

[0003] In actual production, in order to facilitate the stable connection with the external circuit, threaded holes are generally provided on the surface of the interface part, and the external circuit is directly connected to the pole through bolts, which requires a large torque between the interface part and the sealing plate. It will not slide or fall off. For the composite pole welded by friction welding, due to the difference in thermal expansion coefficient between the interface part and the sealing plate part, it is easy to cause thermal stress during welding, so that there will be a large welding deformation after welding, and the welding interface is easy to produce Cracks, or even fractures, the connection strength is not high, and it is difficult to withstand large torsional forces

Abstract

The invention relates to the technical field of battery pole processing, in particular to a new energy power battery pole forging processing technology and a forging device thereof.The new energy power battery pole forging processing technology comprises a bottom plate, a stamping assembly is fixedly installed on the top face of the bottom plate, supporting legs are fixedly connected to the four top corners of the top face of the bottom plate, and a top plate is fixedly connected between the top ends of the four supporting legs; a fixing seat is fixedly connected to the middle of the bottom face of the top plate, a felt table is fixedly connected to the bottom face of the fixing seat, and a linear motor is fixedly connected to one end of the top face of the top plate. According to the invention, through the arrangement of the fixing module and the pushing mechanism, the composite pole blank is placed on the fixing module, and the interface piece and the sealing plate piece are stamped through the forging head, so that the connection between the interface piece and the sealing plate piece is tighter, and gaps and bubbles between the connection positions of the interface piece and the sealing plate piece are removed or reduced; and meanwhile, an impurity layer on the surface of the sealing plate is peeled off through stamping, and follow-up treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of battery pole processing, in particular to a new energy power battery pole forging process and a forging device thereof. Background technique [0002] The pole is a necessary part of the battery that connects the inside and outside of the battery. One end of the pole is used to connect to the external circuit, and the other end is directly connected to the battery electrode material. In order to meet the needs of different functions at both ends of the pole, composite poles are generally used at present. , the interface piece outside the battery and the sealing plate inside the battery are made of different materials, and the interface piece and the sealing plate are generally connected by friction welding to form an integral composite pole. [0003] In actual production, in order to facilitate the stable connection with the external circuit, threaded holes are generally provided on the surface of the inte...
