Problems solved by technology

[0005] In order to overcome the shortcoming that when the charging and discharging current is too large, gas will be generated in the battery case. Under high temperature conditions, too much gas will cause the lithium battery to explode and affect the use of the lithium battery. Technical problem: provide a working speed Faster extrusion molding machine with clamping function for the production of caps for lithium batteries

Abstract

The invention relates to forming equipment, in particular to extrusion forming equipment for lithium battery cap production. The extrusion forming equipment for lithium battery cap production is high in working speed and has a clamping function. The extrusion forming equipment for lithium battery cap production comprises a base and an extrusion mechanism, wherein the extrusion mechanism is arranged on one side of the top of the base; a cylinder arranged at the upper part of the extrusion mechanism; an extrusion block arranged on a piston rod of the air cylinder; and a placing mechanism arranged on one side of the top of the base, and matched with the extrusion mechanism. Through the action of the piston rod of the air cylinder, the extrusion block is driven to move downwards, meanwhile, the extrusion mechanism moves a lithium battery on the placement mechanism to the extrusion block, the lithium battery cap is subjected to extrusion forming under the action of the extrusion block, the extrusion forming speed is high, and the working efficiency of people is effectively improved.

Description

technical field [0001] The invention relates to a molding device, in particular to an extrusion molding device for lithium battery cap production. Background technique [0002] Lithium batteries use lithium metal or lithium alloy as the negative electrode material and use non-aqueous electrolyte solution. Unlike other batteries, lithium batteries have the characteristics of high charging density, long life and unit cost. [0003] The lithium battery shell is equipped with a battery winding core and electrolyte. If there is a short circuit or too much water inside, or when the charging and discharging current is too large, gas will be generated in the battery shell. The explosion of the lithium battery will affect the use of the lithium battery. In view of this, the open end of the lithium battery casing needs to be sealed by a battery cap, which can ensure the safety of the high-power lithium battery and improve the working efficiency of the lithium battery. [0004] To sum...
