Embodiment 1

[0010] Example 1: The mixed rubber is subjected to rough refining and refining successively. After thermal refining, the temperature of the rubber material is controlled at 80±5°C, and it enters the three-roll calender through the automatic continuous rubber supply conveyor belt for calendering. The upper part of the three-roll calender calender The temperature of the roll is controlled at 85°C, the temperature of the middle roll is controlled at 75°C, and the temperature of the bottom roll is controlled at 40°C. The extruded film is cut by a hob and then air-cooled. After cooling, the temperature of the film can reach 32°C, and then passes through the four-column hydraulic pressure The slicer slices, and finally the film is weighed and stacked on the shutter car according to the rubber quality of each vibration-isolation rubber bearing. Compared with the prior art, the surface of the film is smooth, free from oil stains, and has less air bubbles, which can shorten the film mak...

Embodiment 2

[0011] Example 2: The mixed rubber is subjected to rough refining and refining successively. After thermal refining, the temperature of the rubber material is controlled at 90±5°C, and it enters the three-roll calender through the automatic continuous rubber supply conveyor belt for calendering. The upper part of the three-roll calender calender The temperature of the roll is controlled at 80°C, the temperature of the middle roll is controlled at 70°C, and the temperature of the bottom roll is controlled at 30°C. The extruded film is cut by a hob and then air-cooled. After cooling, the temperature of the film is controlled at 31°C, and then passed through the four-column hydraulic The slicer slices, and finally the film is weighed and stacked on the shutter car according to the rubber quality of each vibration-isolation rubber bearing. Compared with the prior art, the surface of the film is smooth, free from oil stains, and has less air bubbles, which can shorten the film makin...

[0012] Example 3: The mixed rubber is subjected to rough refining and refining successively. After thermal refining, the temperature of the rubber material is controlled at 90±5°C, and it enters the three-roll calender through the automatic continuous rubber supply conveyor belt for calendering. The upper part of the three-roll calender calender The temperature of the roll is controlled at 75°C, the temperature of the middle roll is controlled at 72°C, and the temperature of the bottom roll is controlled at 22°C. The extruded film is cut by a hob and then air-cooled. After cooling, the temperature of the film is controlled at 30°C, and then passed through the four-column hydraulic The slicer slices, and finally the film is weighed and stacked on the shutter car according to the rubber quality of each vibration-isolation rubber bearing.

Abstract

The invention discloses a manufacture process for the inner layer rubber calendaring sheet of a shock-insulation rubber supporting base, and belongs to the technical field of rubber products. The process comprises the steps of: coarse smelting and refining rubber compound successively, wherein the temperature of a rubber material after heat refining is controlled to be 90+ / -5 degrees centigrade; sending the treated rubber compound into a three-roller calendar through an automatic successive rubber-feeding conveyor belt for calendaring, wherein the temperature of an upper roller of the three-roller calendar is controlled to be 70-85 degrees centigrade, the temperature of a middle roller is controlled to be 60-75 degrees centigrade, and the temperature of a lower roller is controlled to be 20-40 degrees centigrade; cropping calendared rubber films by a rolling cutter and then forcibly cooling by a fan, wherein the temperature of the cooled rubber film is controlled to be 30+ / -2 degrees centigrade; then cutting the cooled rubber film into slices by a four-column hydraulic slicer; and finally weighing the rubber films and collecting according to the rubber weight of each shock-insulation rubber supporting base. According to the process provided by the invention, inner layer rubber with different thicknesses and weights can be manufactured; the surface of the inner layer rubber is smooth, and has no oil stain and small in bubble number; and the rubber film manufacture time for the shock-insulation rubber supporting base can be shortened, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a manufacturing process of calendering sheets of inner layer rubber of shock-isolation rubber bearings, belonging to the technical field of rubber products. Background technique [0002] The shock-isolation rubber bearing is a thick product building material composed of rubber and steel plate. The inner film is rubber sheets of different diameters, different thicknesses, and different qualities. The uniformity of the film is very high. Due to the different models and specifications of the shock-isolation rubber bearings, the quality of each batch of steel plates is different, and the quality of the steel plates is different. Therefore, each isolation There are differences in the rubber filling amount of the vibration rubber bearing. In order to increase the qualification rate of the isolation bearing to over 99.5%, it is necessary to control the thickness and quality of the rubber sheet according to the quality of the steel pl...
