Description

Technical Field

[0001] This utility model relates to the field of industrial parts processing, specifically a ferrite core forming and slitting device. Background Technology

[0002] With the rapid innovation in new energy, automotive electronics, and high-end manufacturing, the market demand for ferrite cores, as core components of high-frequency magnetic materials, continues to grow. Ferrite cores, with their high resistivity, excellent dielectric properties, and high-frequency permeability, are widely used in transformers, inductors, and communication equipment. To meet the demands of intelligent manufacturing, the industry has placed higher requirements on the precision, efficiency, and automation level of core slitting equipment. Traditional slitting processes suffer from high core breakage rates and low yields due to issues such as stress concentration and positioning deviations, making them unsuitable for large-scale production. Against this backdrop, developing new slitting equipment to optimize the cutting process and improve product quality has become a key direction for technological upgrading in the industry.

[0003] Currently, ferrite core slitting mainly relies on traditional mechanical cutting or manual separation. Traditional equipment typically uses single-blade direct cutting or stamping methods to segment the core through a fixed blade position. While these methods achieve basic cutting functionality, they have significant drawbacks: firstly, the blade directly contacts the core during cutting, easily leading to stress concentration and breakage at the cutting point; secondly, the equipment lacks a pre-positioning mechanism, requiring manual calibration of the cutting position, resulting in low efficiency and large errors; and thirdly, adjusting the cutting length is complex and difficult to meet the diverse product requirements. Furthermore, some companies still manually separate sintered and bonded cores, which is labor-intensive and has a breakage rate exceeding 80%, making it unsuitable for modern production pace.

[0004] The typical process of traditional slitting equipment includes: placing the sintered magnetic core blank on a support platform and fixing it with a clamping device; driving the shearing cylinder to move the cutting blade vertically downward to complete the segmented cutting; and the cut magnetic core sliding down the discharge plate to the collection box. Some equipment uses a vibration motor to assist in magnetic core separation, but the core cutting action still relies on the direct action of the blade. To control the cutting length, the limit baffle needs to be manually adjusted or the cutter head needs to be replaced, which is cumbersome and time-consuming. Although this process can achieve basic slitting, it is difficult to overcome the bottlenecks in cutting stress control, positioning accuracy, and automation.

[0005] There are several issues with the cutting technology, including problems with "cutting stress control" and "pre-positioning accuracy." For example, the instantaneous impact force caused by direct cutting can easily cause the magnetic core to break, especially in the field of precision electronic components, where the breakage rate can be as high as 30%, seriously affecting product yield. Secondly, there is a lack of a pre-cutting marking mechanism, and the cutting position relies on manual experience for calibration, with an error of up to ±0.5mm, which cannot meet the high precision requirements. Thirdly, the equipment has a low degree of automation, requiring manual intervention in feeding, positioning, and unloading, and the production efficiency is only 1 / 3 of that of new equipment. SUMMARY

[0006] Therefore, the ferrite core forming and slitting device is provided to solve the technical problem that the instantaneous impact force caused by direct cutting easily leads to the fragmentation of the magnetic core.
