Embodiment 1

[0033] A method for manufacturing a leather cup for high-speed rotating shaft seals (as attached Figure 1~5 shown).

[0034] A method for manufacturing a leather cup for high-speed rotating shaft seals. The material of the cup is FX-4 fluororubber; The lip is machined;

[0035] Before using the direct molding method to manufacture leather cups, it is necessary to apply glue to the metal inner frame; the relevant process requirements for the glue treatment are: apply 2# adhesive on the metal inner frame, and dry it at room temperature for 30 to 40 minutes; Then apply 1# adhesive; then carry out room temperature drying and high temperature drying in sequence; the thickness of each coating is 0.1~0.2mm;

[0036] The 2# adhesive is specifically FXY-4, and the 1# adhesive is specifically FXY-7; the room temperature drying requires 23-30°C, and the drying time is 20-30 minutes; the high-temperature drying specifically requires 120-143°C , The drying time is 30-60 minutes.

Abstract

The invention relates to a manufacture method for a leather cup for sealing a high-speed rotation shaft. The leather cup is made of FX-4 fluorous rubber. The method comprises the following steps that the direct molding pressing forming is adopted, and then, the subsequent treatment of primary vulcanization, secondary vulcanization and mechanical processing treatment on lips are carried out. The manufacture method is characterized in that before the leather cup manufacture through the direct molding pressing forming, a metal inner framework firstly needs the glue coating treatment, the process has the technical requirements that 2# binding agents are coated on the metal inner framework, the drying is carried out for 30 to 40 minutes at the room temperate, then, 1# binding agents are coated, then, the room-temperature drying and the high-temperature drying are carried out, the glue coating thickness in each time is 0.1 to 0.2mm, the 2# binding agents are FXY-4, the 1# binding agents are FXY-7, the room-temperature drying requires the temperature being 23 to 30 DEG C and the drying time being 20 to 30 minutes, and the high-temperature drying has the concrete requirements of the temperature being 120 to 143 DEG C and the drying time being 30 to 60 minutes. In the manufacture method, the aspects such as metal inner framework binding and the like are greatly improved, and a good technical effect is correspondingly realized.

Description

Technical field: [0001] The invention relates to the technical field of manufacturing a leather cup for sealing a high-speed rotating shaft, and in particular provides a method for manufacturing a leather cup for sealing a high-speed rotating shaft.
