Machining method of roller structural part

Abstract

The invention discloses a machining method of a roller structural part. The machining method comprises the following steps: the roller structural part required to be provided with a bracket is tightly pressed on a fixed bracket to be cast through an S-shaped elastic piece; the roller structural part and the fixed bracket are respectively connected to the two ends of the S-shaped elastic piece; after a preset mold is qualified, the roller structural part, the S-shaped elastic piece and the fixed bracket are put into the preset mold as a whole, and prepared molten metal is poured into the preset mold for casting together through a casting machine by a continuous steel casting method; the melting point of the S-shaped elastic piece is higher than the melting point of the prepared molten metal; and when the casting is finished, and a steel bottle to accommodate the prepared molten metal has no bubbles, the mechanical steel lifting is performed, and residues in the steel bottle are recovered. The machining method of the roller structural part has high production efficiency, good product quality and low machining cost.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a processing method for a roll-shaped structural member. Background technique [0002] The roll-shaped structural member is a rubber roll used in combination with a cooling roll and a calender roll in extrusion coating and calender coating, respectively. [0003] The function of the roll structure 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 roller-shaped structural member bracket used in conjunction with the roller-shaped structural member can be made of aluminum die-casting parts to make the fixing frame, and fixed on the S-shaped elastic piece by riveting.
