Abstract

The invention discloses a manufacturing method of an explosion-proof head cover plate. Manufacturing is carried out by an integrated processing and molding method of an explosion-proof plate and the explosion-proof head cover plate. Firstly, an explosion-proof head cover plate blank is machined by a stamping method; secondly, an explosion-proof plate blank which is locally thinned is directly machined on the explosion-proof head cover plate blank through CNC machining; and finally, a burst score of the explosion-proof plate is machined on the explosion-proof plate blank obtained through CNC machining by a press compacting method. By the manufacturing method of the explosion-proof head cover plate, stamping, thermal treatment and detection procedures of the individual explosion-proof plate, a welding procedure of the explosion-proof plate and the head cover plate, a seal testing procedure of a welding line and the like are omitted; and the material and processing cost are reduced.

Description

technical field [0001] The invention relates to the technical field of making an explosion-proof roof sheet, in particular to a method for manufacturing an explosion-proof roof sheet. Background technique [0002] During the use of the power battery, due to short circuit, overcharge, overdischarge and other reasons, high temperature and high pressure gas may be generated inside the battery. If these gases cannot be discharged to the outside of the battery in time, the battery may explode and disintegrate, catch fire, and serious accident. Therefore, the power battery is generally equipped with an explosion-proof device for releasing the high-temperature and high-pressure gas inside the battery in time. [0003] The current power battery explosion-proof top cover sheet adopts a split type explosion-proof sheet, and its production method and process are as follows: 1. Pre-process the explosion-proof through hole on the metal top cover sheet of the power battery, and at the sa...
