Rubber sealing ring press-cutting forming processing method

Abstract

The invention belongs to the technical field of rubber sealing elements, and particularly relates to a rubber sealing ring press-cutting forming processing method which is completed by adopting a rubber sealing ring press-cutting forming processing machine in a matched mode. The method comprises the following steps that 1, a rubber sheet is fixed, specifically, the rubber sheet is horizontally placed on the upper surface of a base; 2, vertical cutting is conducted, specifically, a first annular blade and a second annular blade are driven to cut the rubber sheet in the vertical direction; 3, rotary cutting is conducted, specifically, a first annular blade and a second annular blade are driven to rotate in opposite directions, and therefore the rubber sheet is rotationally cut; and 4, returning and stripping are conducted, specifically, the first annular blade and the second annular blade are driven to vertically move upwards. The rubber sealing ring and a rubber wafer automatically fall off under the action of air pressure. The smooth cutting surface is ensured, rotation of the rubber sheet is avoided, and the cutting efficiency is improved; and the rubber sealing ring does not need to be manually taken out by an operator, the efficiency is improved, and injury to the operator is avoided.

Description

technical field [0001] The invention belongs to the technical field of rubber seals, and in particular relates to a press-cutting molding processing method for a rubber seal ring. Background technique [0002] The rubber sealing ring is an annular cover composed of one or several parts, which is fixed on a ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and the intrusion of foreign objects. Rubber sealing rings can be divided into mouth-shaped sealing rings, O-shaped sealing rings, C-shaped sealing rings, V-shaped sealing rings and Y-shaped sealing rings according to the cross-sectional shape. lock up. When the mouth seal is processed, the rubber needs to be pressed into a rubber sheet with uniform thickness, and then the rubber sheet is pressed and cut with two coaxial annular blades. At present, there are the following problems in the processing of the mouth-shaped sealing ri...

Problems solved by technology

[0004] The invention provides a rubber sealing ring press-cutting molding processing method, the purpose of which is to solve the following problems in the current process of matching the mouth-shaped sealing ring: (1) when the rubber sheet is pressed and cut, the ring blade is directly perpendicular to the rubber It is difficult to ensure the smoothness of the cutting surface when the sheet is press-cut; the circular blade is perpendicular to the rubber sheet and rotates the press-cut at the same time to improve the smoothness of the cutting surface, but the rubber sheet is easy to rotate synchronously with the ring blade under the action of friction during the cutting process. Reduced cutting efficiency; (2) After the rubber sheet is pressed and cut, the cut rubber sealing ring will remain between the two annular blades, and the circular rubber sheet will also remain in the inner blade, which needs to be taken out manually , the efficiency is low and the ring blade is easy to cause injury to the operator
