Embodiment Construction
[0019] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0020] Such as figure 1 As shown, a cold-pressing method for a battery pole, first prepares a positioning device 6 , an ejector 14 , a bottom plate part 19 , and an upper plate part 18 with sizes corresponding to each other, and forms a device for cold-pressing a battery pole after assembly. Install the device for cold-pressed battery poles on the press, turn on the power of the press, adjust the pressure, start the press, and cold-press the positive and negative poles on the battery. The manufacturing process of the cold-pressed battery pole device is as follows:
[0021] Such as image 3 with Figure 4 As shown, first prepare the positioning device and the ejector device:
[0022] attached image 3 The preparation process of the positi...

The invention relates to a cold press method of electrode posts of a cell. The method comprises the following processes: 1, manufacturing a positioning device; 2, manufacturing an injection device; 3, manufacturing a bottom plate part; 4, manufacturing an upper plate part; and 5, carrying out cold press on an anode and cathode post of the cell. According to the invention, the upper plate part and the lower plate part on a press need the guide of a guide pillar and a guide sleeve; when the upper board part is pressed a tapered iron head plate drives a side head of a cathode post to move left to a head of the anode and cathode post, an upper side head of an anode post to move downward to the head of the anode and cathode post to make the upper head of the anode post, the head of the anode and cathode post and a lower head of the cathode post to be sealed; and the electrode posts are formed through cold press when spacing planes merge. The consistency of the cell with cold pressed anode and cathode posts through the method of the present invention is good, the electrode posts of the cell are firm and reliable, and the work efficiency is high.
Description
technical field [0001] The invention belongs to the technical field of mechanically crimping battery poles, in particular to a cold pressing method for battery poles. Background technique [0002] With the rapid development of electronic technology, the application range of batteries is becoming wider and wider, and the varieties and specifications of batteries are also increasing. At present, when assembling the pole of the battery, most of the poles are manually placed on the clamp, one person fixes it manually, and one person operates the clamp to crimp, measure the size after pressing, and perform a second cold press if it does not meet the requirements . Such a method of cold-pressing the battery pole has low working efficiency, poor battery pole firmness and battery consistency, and it is difficult to meet the market's increasingly higher requirements for battery quality. Contents of the invention [0003] In order to solve the technical problems existing in the kn...
