AI Technical Summary

Technical Problem

Traditional rare earth wire feeders suffer from problems such as high rare earth wire oxidation rate, non-adjustable wire feeding speed, uneven rare earth distribution, and difficulty in degassing the furnace, resulting in low rare earth utilization and short equipment life.

Method used

Using a combination of protective rollers and support rollers, ceramic blades are rotated by inert gas for stirring. Combined with a lifting component to control the insertion depth of the graphite shaft, the uniform distribution of rare earth elements is achieved. The wire feeding speed and orderly wire feeding are controlled by a motor.

Benefits of technology

It reduces the rare earth oxidation loss rate, improves the uniformity of rare earth distribution and the orderliness of wire feeding, and extends the service life of the equipment.

Abstract

The utility model discloses a rare earth wire feeding device which comprises a shell, a wire feeding assembly, a protection roller, a supporting roller and a graphite shaft. A supporting roller is horizontally and longitudinally arranged on the left side of the middle inside the shell, a graphite shaft is horizontally and transversely arranged on the left end face of the supporting roller, and the left end of the graphite shaft vertically extends out of the shell and then obliquely extends downwards towards the left side. A protection roller is vertically arranged on the upper end face of the supporting roller, and the upper end of the protection roller is connected with the inner top face of the shell. A through hole I vertically penetrates through the upper surface of the shell relative to the position of the protective roller, and a wire feeding assembly is arranged on the side, relative to the through hole I, of the upper surface of the shell; a channel I is coaxially formed in the position, opposite to the through hole I, of the upper end face of the protection roller in a penetrating mode, the lower end of the channel I penetrates in from the joint of the protection roller and the supporting roller, then penetrates out from the joint of the supporting roller and the graphite shaft in an arc shape and extends out of the left end face of the graphite shaft in the length direction of the graphite shaft, and then wire feeding operation is conducted. According to the utility model, the oxidation loss rate is reduced.
