Abstract

The invention relates to the technical field of batteries, discloses a forming technology of a side-welding connecting piece, and provides a stamping die. The stamping die comprises a pier press die,a blanking die and an edge bending die. The forming technology comprises the following steps that (1) a metal blank material is cut into a plurality of connecting raw pieces; (2) the upper end of eachconnecting raw piece is processed by the pier press die in a pier press mode to be in a sheet shape, and the two sides of the lower end of each connecting raw piece are processed in a forging and pressing mode to form welding lugs; (3) fusing holes are formed in the bending positions between the welding lugs on the two sides and each connecting raw piece in a blanking mode by the use of the blanking die; and (4) the upper end of each connecting raw piece is bent by the edge bending die to form a conducting strip, a welding piece is formed at the lower end of each connecting raw piece, and thecorresponding welding lugs on the two sides are bent in the positive direction. Due to the fact that the two sides of the lower end of each connecting raw piece are processed in a pier press mode, the portions of connection between the welding lugs and the connecting raw pieces can be thinned, the welding lugs can be conveniently bent, the bending forming technology of the welding lugs is simpler, the material waste is reduced, and the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to the forming process of side welding connecting pieces. Background technique [0002] At present, with the increasing miniaturization, portability and portability of electronic products, such as cameras, notebooks and mobile phones, the driving power of these electronic products is also developing in the direction of high capacity, high safety and portability. Its excellent characteristics such as high capacity are widely used in electronic products. [0003] The lithium battery includes a casing, a battery top cover, and a battery cell, etc., wherein the battery cell is placed inside the casing, the upper end of the casing has an upper end opening, and the battery top cover is closed in the upper opening of the casing, and the battery top cover is set There is a conductive block, the lower part of the conductive block is connected to the battery cell through the connecting pie...
