Problems solved by technology

[0003] Existing floating oil seals for excavators need to be quenched during production and processing, and the quenching process is mainly performed manually. In operation, the floating oil seal is heated to a certain temperature and then thrown into cold water. To achieve the purpose of rapid cooling, however, due to the precision of the floating oil seal in the industry
[0004] The tightness requirements are high, and it is difficult to ensure the uniformity of the heating of each part of the floating oil seal by manually heating the floating oil seal, and the method of manually quenching the floating oil seal still has the problems of cumbersome operation and low efficiency. For this reason, we propose high sealing Production technology and processing equipment of floating oil seal for excavator

Abstract

The invention discloses a process of floating oil seal production for a high-sealing excavator and processing equipment of the floating oil seal production for the high-sealing excavator. The processcomprises the following steps of conducting film coating through a rubber mold, sand-forming a mold, assembling a pouring mold, manufacturing molten iron, and pouring the molten iron into the mold, 3,carrying out floating seal curing for 15-20 minutes, 4, carrying out shot blasting treatment on a product subjected to the floating seal curing, and carrying out performances detection, and 5, conducting quenching treatment, specifically, in a quenching process, adopting quenching equipment for batch quenching, then conducting cooling treatment in an aqueous solution, and then conducting coolingtreatment, so that enabling the mold to be formed. Through arrangement of an automatic adjustment moving and quenching mechanism, traditional manual operation quenching can be replaced, batch quenching processing can be achieved, and the processing efficiency and the processing safety are improved.

Description

technical field [0001] The invention relates to the technical field of oil seal processing, in particular to a production process and processing equipment for a floating oil seal for a high-tightness excavator. Background technique [0002] Floating oil seal is a common name of floating seal, which belongs to a kind of mechanical seal in dynamic seal. The seal is mainly used in low-speed and heavy-duty occasions. It has the advantages of automatic compensation after wear and end face wear, reliable operation, and simple structure. It is widely used in coal mining machinery. [0003] Existing floating oil seals for excavators need to be quenched during production and processing. Manual quenching is mainly used. In operation, the floating oil seal is heated to a certain temperature and then thrown into cold water to To achieve the purpose of rapid cooling, however, due to the precision of the floating oil seal in the industry [0004] The tightness requirements are high, and...
