Production process for oil seal

A production process and oil seal technology, which is applied in the direction of manufacturing tools, metal processing, grinding workpiece supports, etc., can solve the problems of reducing the processing efficiency of rubber rings, the inability to achieve grinding, and the deformation of rubber rings, so as to improve the grinding effect and reduce scratches. Injury, increase the effect of friction

Problems solved by technology

However, this grinding method can only polish the inner wall, and for the rubber ring with low hardness, if the grinding rod just contacts the inner wall, the rubber ring may be deformed and cannot be polished; if the grinding rod is pressed against the inner wall of the rubber ring, there will be It may cause the rubber ring and the grinding rod to rotate synchronously. The grinding rod is always in contact with a point on the inner wall of the rubber ring, and grinding cannot be achieved; in addition, in order to improve the adhesion effect between the rubber ring and the skeleton, it is necessary to punch a hole on the inner wall of the rubber ring after grinding. Holes, when installing the rubber ring, cooperate with the protrusion on the skeleton to improve its stability, which undoubtedly increases the process and reduces the processing efficiency of the rubber ring

Abstract

The invention relates to the field of oil seals, in particular to a production process of an oil seal. The production process of the oil seal comprises the following steps: step 1, preparing a grinding agent for subsequent use; step 2, preparing grinding and piercing equipment; step 3, coating the inner wall and the outer wall of a rubber ring with the grinding agent; step 4, grinding; and step 5,piercing. By the technical scheme, the inner wall and the outer wall of the rubber ring can be ground, and meanwhile, the inner wall of the rubber ring is pierced.

Description

technical field [0001] The invention relates to the field of oil seals, in particular to a production process of the oil seals. Background technique [0002] The oil seal of a crane is generally composed of a skeleton, a spring and a rubber ring. The function of the rubber ring is to isolate the parts that need to be lubricated in the transmission parts from the external environment, so as not to allow the lubricating oil to leak. In the production process of the rubber ring, in order to ensure that the amount of raw pulp is sufficient, it is necessary to add excess slurry to the mold. When the slurry is full of the mold, the excess slurry will overflow from the buckle of the mold. Burrs will form. After the rubber ring is formed, the burrs need to be polished to improve the fit between the rubber ring and the skeleton to ensure that the lubricating oil will not leak during use. [0003] Traditional rubber ring grinding is usually done manually, that is, the operator holds...
