Manufacturing method of hardware structure part

Abstract

The invention discloses a manufacturing method of a hardware structure part. The manufacturing method of the hardware structure part includes: tightly pressing the hardware structure part which needs a support on a fixing support to be casted through a Z-shaped positioning piece; respectively connecting the hardware structure part and the fixing support with two ends of the Z-shaped positioning piece; placing the hardware structure part, the Z-shaped positioning piece and the fixing support into a preinstalled mold as a whole, and pouring melting metal liquid prepared in advance into the preinstalled mold so as to cast the melting metal liquid together with the hardware structure part, the Z-shaped positioning piece and the fixing support through a casting machine by using a mold casting method; enabling a fusion point of the Z-shaped positioning piece to exceed a fusion point of the melting metal liquid prepared in advance; performing mechanical steel releasing when no bubble emerges in a steel bottle used to contain the melting metal liquid prepared in advance after casting is completed, and then recycling residues in the steel bottle; performing polishing and antirust coat spraying treatment on the hardware structure part cooled to room temperature after the hardware structure part completely casted is cooled to the room temperature. The manufacturing method of the hardware structure part is high in production efficiency, good in product quality and low in manufacturing cost.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a method for manufacturing a hardware structural part. Background technique [0002] Hardware structural parts are rubber rollers used in combination with cooling rollers and calendering rollers in extrusion coating and calender coating. [0003] The function of the hardware 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 hardware structure bracket used in conjunction with the hardware structure can be made of aluminum die-casting parts to make the fixing frame, and fixed on the Z-shaped positioning piece by riveting. The joining process of riveting has la...
