Description
Technical Field
The invention relates to the technical field of oil seal production, in particular to a large oil seal production process and oil seal bonding equipment.
Background
Rotary shaft lip seals (often referred to as oil seals) are most commonly vulcanized from rubber. Along with the gradual upsizing of equipment such as wind power generation, shield propulsion construction and the like, the size of the matched rubber oil seal is larger and larger, and the specification of a vulcanizing machine required by the rubber oil seal forming is larger and larger.
The conventional oil seal production mode is that a vulcanizer is adopted to mold and vulcanize to form. The structure of the vulcanizer is shown in fig. 1, in which the reference numbers are: 101-upper beam, 102-heat insulating layer, 103-hot plate, 104-column shoulder, 105-mould 106-hot plate, 107-heat insulating layer, 108-plunger platform, 109-plunger, 110-sealing sleeve and 111-hydraulic cylinder. Vulcanization is a process in which raw rubber is kept under a certain pressure and temperature for a certain time to become vulcanized rubber (i.e., a cured rubber), thereby having a certain shape, strength and hardness. And (4) after vulcanization, trimming to obtain a finished product which can leave a factory. The working principle of the vulcanizing machine is as follows: referring to fig. 1, the mold 105 is a cavity for curing raw rubber, and the cavity is closed by upward pressing of a plunger of a hydraulic cylinder 111. At the same time, the power supply conducts heat to the mold to raise the temperature through the upper and lower hot plates 103 and 106. The green rubber is cured in the cavity to a cured rubber at a set pressure and temperature for a set time, and the mold 105 is opened and removed. And after cooling the boiled rubber, trimming to obtain the oil seal product.
The existing oil seal production mode has certain defects: when the size of the oil sealed product is larger, the size of the mold 105 is correspondingly increased, the sizes of the two hot plates 103 and 106 are larger, and the pressurizing and heating are more time-consuming and labor-consuming, so that the whole vulcanizing machine is too large to operate and too high in cost to bear. For example, to produce an oil-sealed product with a diameter of 2 meters, the die is at least 2.5 meters, the hot plate and plunger platform are at least 3 meters, the pressure of the hydraulic cylinder and the electricity for heating are huge, and the price of the oil-sealed product is high enough to be difficult to bear by the market.
On one hand, the gradually-enlarged equipment needs an oil seal with the diameter of more than 4 meters, and on the other hand, the current largest vulcanizing machine does not exceed 4 meters, so that the production is difficult. In view of the current situation, a new technology for producing a large oil seal is urgently needed to solve the above problems.
