A glass lubricant coating device for high-temperature blanks in hot extrusion process

Abstract

The invention discloses a glass lubricant coating device of a high-temperature blank in a hot extrusion process. The coating device comprises a frame, a frame vertical plate, a water circulating mechanism and a washing mechanism, wherein the washing mechanism is fixed on the frame vertical plate through a shaft sleeve; the water circulating mechanism is communicated with the washing mechanism; the washing mechanism comprises an inner wall washing roller, an outer wall washing roller and rotation hand shanks; the inner wall washing roller and the outer wall washing roller are of the same sleeve structures; a charge cavity, a buffer cavity and a cooling cavity are orderly arranged between pipe barrels inside the sleeve from inside to outside; a discharge hole is formed between the pipe barrels; the rotation hand shanks are respectively arranged at one ends of the inner wall washing roller and the outer wall washing roller. The glass lubricant coating device is simple in structure, and simple and convenient to operate, and the problem that the glass lubricant is molten due to over-high temperature of the high-temperature blank, resulting in uneven coating and the like of the glass lubricant is effectively solved.

Description

technical field [0001] The invention relates to a glass lubricant spraying device, in particular to a glass lubricant coating device suitable for seamless steel pipe blanks in a hot extrusion process, and belongs to the technical field of metal processing. Background technique [0002] The hot extrusion process is a common method for metal thermoforming. In order to reduce the resistance of the extrusion tool to the metal surface during the extrusion process, reduce the unevenness of the metal flow, and improve the performance parameters of the extruded product, most of them need to be coated with glass. Powder is used as a lubricant. The use of glass lubricant in the hot extrusion process will make it have better ductility and pressure resistance during the metal deformation process. The glass lubricant has a small thermal conductivity, good lubricating performance, and has good wettability to deformed metals. And binding force, it is conducive to the peeling off of the gl...

AI Technical Summary

Problems solved by technology

At present, the roller brush type glass lubricant coating device is mostly used in the coating equipment. The roller brush is fixed and cannot be adjusted. The structure is complex and the heat dissipation is poor. It is easy to cause local overheating of the roller brush and uneven spraying of the glass lubricant. , time-consuming and inconvenient to use
