AI Technical Summary

Technical Problem

Traditional cylindrical battery steel shell flanging forming equipment suffers from low flanging efficiency and poor versatility of positioning and stamping fixtures, resulting in low processing efficiency and cumbersome operation.

Method used

The system employs a double hollow sliding table for alternating positioning operations, combined with multiple pre-set steel shell placement cylinders and stamping and flanging mechanisms. Through horizontal and vertical switching mechanisms, it achieves synchronous stamping and flanging, workpiece loading, and finished product unloading, enabling rapid replacement of positioning fixtures. Precise control and automation enhance processing efficiency and accuracy.

Benefits of technology

It significantly improves the overall processing efficiency of flanged steel shell ends of cylindrical batteries, adapts to the needs of large-scale mass production, reduces downtime, ensures flanged forming accuracy and product consistency, reduces labor costs, and is suitable for flexible processing of multiple steel shell models.

Abstract

This invention provides a cylindrical battery steel shell end flanging forming mechanism. It relates to the technical field of battery steel shell processing equipment. The cylindrical battery steel shell end flanging forming mechanism includes a support base and a U-shaped bracket fixedly installed on the top of the support base. A horizontal shifting mechanism is provided above the support base, and two U-shaped frames are provided on the horizontal shifting mechanism. A transverse shifting shaft is rotatably mounted on each of the two U-shaped frames. A bearing beam is fixedly mounted at the far ends of the two transverse shifting shafts. A support frame is fixedly mounted on each of the two bearing beams. A hollow sliding stage is slidably mounted above each of the two support stages. Multiple steel shell placement cylinders can be detachably mounted on each of the two hollow sliding stages. This invention can significantly improve continuous flanging efficiency and can quickly switch between corresponding positioning fixtures and stamping flanging fixtures according to the steel shell model.
