Film rolling forming machine for small-particle-size yttrium oxide substrate and preparation process of film rolling forming machine

Abstract

The invention discloses a roll forming machine for a small-particle-size yttrium oxide substrate, which comprises a machine base, a control console and a feeding box are fixedly mounted on the machine base, a base is fixedly mounted on the machine base, a guide seat is fixedly mounted in the base, rollers are rotatably mounted on the guide seat, the rollers comprise an upper roller and a lower roller, and the upper roller and the lower roller are fixedly mounted on the machine base. A roller is arranged on the base and is driven by a driving shaft, a limiting rod is fixedly arranged on the base, a movable seat is arranged on the limiting rod in a sliding manner, the movable seat is driven by a driving structure with a blank edge aligning function, and a main blowing seat is fixedly arranged on the guide seat; the solvent limiting structure is arranged, the effect of eliminating solvent tension influence is achieved, a solvent extruded by the roller can flow in the blank moving direction, and the situation that internal stress exists after a substrate is formed, and the strength is damaged is avoided. Through the preparation process for the small-particle-size yttrium oxide substrate, the finished product quality of the small-particle-size yttrium oxide substrate is improved.

Description

technical field [0001] The invention relates to the technical field of ceramic substrates, in particular to a rolling-film forming machine for yttrium oxide substrates with small particle size and a preparation process thereof. Background technique [0002] Yttrium oxide is an important high temperature resistant ceramic material that is often used in superconducting materials and many cutting-edge applications in the electronics industry. The yttrium oxide substrate usually adopts the yttrium oxide raw material with small particle size, and is formed by a film rolling machine. The rolling process of the existing yttrium oxide substrate film rolling machine is: the gap between the upper roll and the lower roll is the base In the film rolling station of the sheet, the blanks equipped with yttrium oxide raw materials and binders are sent to the film rolling station, and the blanks are gradually formed by the extrusion action of the upper and lower rollers, and the solvent in t...

Problems solved by technology

[0003]Now in the process of processing, the billet passes between two rollers, the thickness decreases, the width increases, the solvent in the billet is squeezed out by pressure, and at the same time There are two behaviors of volatilization and flow, and the tension between the solvent and the roller is easy to pull the solvent to both sides of the substrate blank, so that the surface of the processed substrate is uneven and has defects, and due to the internal stress The mechanical strength of the substrate is not up to standard

At present, in order to alleviate this problem, some rolling machines use large-diameter rolls and reduce tension through material selection, but with little effect
