Machining method for press roller support

Abstract

The invention discloses a machining method for a press roller support. The machining method includes the steps that a pouring die is arranged on the basis of a fixed support to be poured, and the needed fixed support is obtained through pouring of the pouring die; the fixed support obtained through pouring is calcined, cooled with water, grinded and polished, and grinding dust on the surface of the fixed support is blown away through a blower; a press roller needing to be provided with the support is pressed on the fixed support to be poured through a U-shaped positioning piece and a pressing block; the press roller and the fixed support are connected to the two ends of the U-shaped positioning piece and the two ends of the pressing block respectively; the pressing block is a metal pressing block arranged to be in magnetic attraction with the U-shaped positioning piece; the press roller, the U-shaped positioning piece and the pressing block are pressed and put into a preset die together with the fixed support as a whole, and molten metal liquid prepared in advance is poured into the preset die to be poured together through a pouring machine by adopting a die pouring method. The machining method for the press roller support has the advantages of being high in production efficiency, good in product quality and low in machining cost.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a processing method of a pressure roller bracket. Background technique [0002] Press rolls are rubber rolls used in combination with cooling rolls and calender rolls in extrusion coating and calender coating, respectively. [0003] The function of the pressure roller is to press the extruded or calendered film evenly with the substrate. In the adhesive tape manufacturing process, the adhesive-coated substrate and the release material can also be pressed together. Sometimes it also refers to the rubber roller on the embossing machine, which can cooperate with the engraved roller to emboss evenly on the sheet. [0004] The pressure roller support used in conjunction with the pressure roller can be made of aluminum die-casting parts to manufacture the fixed frame, and fixed on the U-shaped positioning piece and the pressure block by riveting. The joining process of riveting ...
